また表示装置は、平面視において、表示部１１と基板１の端１ｔとの間に表示に寄与しない額縁部１ｇがあり、この額縁部１ｇに発光制御信号線駆動回路、走査信号線駆動回路等が配置される場合がある。この額縁部１ｇの幅はできるだけ小さくすることが要望されている。さらに、一般に、一枚の母基板を切断して複数枚の基板１を切り出すことが行われているが、発光制御部２２に対する切断線の影響を抑えるために、図７のブロック回路図に示すように、最外周部の画素部１５において発光制御部２２を発光素子１４よりも平面視で基板１の内側に配置する構成が提案されている（例えば、特許文献１を参照）。 Further, in the display device, in a plan view, there is a frame portion 1g that does not contribute to the display between the display unit 11 and the end 1t of the substrate 1, and the frame portion 1g includes a light emission control signal line drive circuit, a scanning signal line drive circuit, and the like. May be placed. It is requested that the width of the frame portion 1 g be as small as possible. Further, generally, one mother substrate is cut to cut out a plurality of substrates 1, but in order to suppress the influence of the cutting line on the light emission control unit 22, the block circuit diagram of FIG. 7 is shown. As described above, a configuration has been proposed in which the light emission control unit 22 is arranged inside the substrate 1 in a plan view of the light emitting element 14 in the pixel unit 15 on the outermost periphery (see, for example, Patent Document 1).

なお、画素部１５は、それぞれが赤色発光用の副画素部、緑色発光用の副画素部、青色発光用の副画素部から成る場合がある。赤色発光用の副画素部は赤色ＬＥＤ等から成る赤色発光素子を有し、緑色発光用の副画素部は緑色ＬＥＤ等から成る緑色発光素子を有し、青色発光用の副画素部は青色ＬＥＤ等から成る青色発光素子を有している。例えば、これらの副画素部は、行方向あるいは列方向に並んでいる。 The pixel unit 15 may be composed of a sub-pixel unit for red light emission, a sub-pixel unit for green light emission, and a sub-pixel unit for blue light emission, respectively.

図８は、図７の表示装置における最外周部にある画素部１５（Ｐ１１）を拡大して示す部分拡大平面図であり、図９は、図８のＢ１−Ｂ２線における断面図である。これらの図に示すように、表示装置において、表示部１１の周囲にある表示に寄与しない額縁部１ｇを目立たなくするために、額縁部１ｇにブラックマトリクス等から成る遮光部２５を配置している。 FIG. 8 is a partially enlarged plan view showing an enlarged pixel portion 15 (P11) on the outermost peripheral portion of the display device of FIG. 7, and FIG. 9 is a cross-sectional view taken along the line B1-B2 of FIG. As shown in these figures, in the display device, in order to make the frame portion 1g that does not contribute to the display around the display unit 11 inconspicuous, a light-shielding portion 25 made of a black matrix or the like is arranged on the frame portion 1g. ..

図９に示すように、ガラス基板等から成る基板１上にアクリル樹脂等から成る樹脂絶縁層５１が配置され、樹脂絶縁層５１上に発光素子１４が搭載されている。発光素子１４は基板１の端１ｔから５５μｍ〜１３０μｍ程度離れた位置にある。すなわち、図８における発光素子１４の基板１の端１ｔからの離隔幅Ｌ１は５５μｍ程度であり、離隔幅Ｌ２は１３０μｍ程度である。 As shown in FIG. 9, a resin insulating layer 51 made of acrylic resin or the like is arranged on a substrate 1 made of a glass substrate or the like, and a light emitting element 14 is mounted on the resin insulating layer 51. The light emitting element 14 is located at a position about 55 μm to 130 μm away from the edge 1t of the substrate 1. That is, the separation width L1 from the end 1t of the substrate 1 of the light emitting element 14 in FIG. 8 is about 55 μm, and the separation width L2 is about 130 μm.

発光素子１４は、樹脂絶縁層５１上に配置された正電極５４ａと負電極５４ｂにハンダ等の導電性接続部材を介して電気的に接続されて、樹脂絶縁層５１上に搭載される。正電極５４ａは、Ｍｏ層／Ａｌ層／Ｍｏ層（Ｍｏ層上にＡｌ層、Ｍｏ層が順次積層された積層構造を示す）等から成る電極層５２ａと、それを覆う酸化インジウム錫（Indium Tin Oxide：ＩＴＯ）等から成る透明電極５３ａと、から成る。負電極５４ｂも同様の構成であり、Ｍｏ層／Ａｌ層／Ｍｏ層等から成る電極層５２ｂと、それを覆うＩＴＯ等から成る透明電極５３ｂと、から成る。また、樹脂絶縁層層５１上の正電極５４ａ及び負電極５４ｂよりも基板１の端１ｔ寄りの部位に、電極パッド２ｐが配置されており、電極パッド２ｐは電極層５２ｃとそれを覆うＩＴＯ等から成る透明電極５３ｃとから成る。電極パッド２ｐは、正電極５４ａに電気的に接続されるとともに、側面配線１ｓを介して裏面配線９に電気的に接続される中継電極として機能する。 The light emitting element 14 is electrically connected to the positive electrode 54a and the negative electrode 54b arranged on the resin insulating layer 51 via a conductive connecting member such as solder, and is mounted on the resin insulating layer 51. The positive electrode 54a is an electrode layer 52a composed of a Mo layer / Al layer / Mo layer (indicating a laminated structure in which an Al layer and a Mo layer are sequentially laminated on the Mo layer) and the like, and indium tin oxide (Indium Tin) covering the electrode layer 52a. It is composed of a transparent electrode 53a made of Oxide: ITO) and the like. The negative electrode 54b has the same configuration, and is composed of an electrode layer 52b made of a Mo layer / Al layer / Mo layer or the like, and a transparent electrode 53b made of ITO or the like covering the electrode layer 52b. Further, the electrode pad 2p is arranged on the resin insulating layer 51 at a portion closer to the end 1t of the substrate 1 than the positive electrode 54a and the negative electrode 54b, and the electrode pad 2p is the electrode layer 52c and ITO or the like covering it. It is composed of a transparent electrode 53c and is composed of. The electrode pad 2p functions as a relay electrode that is electrically connected to the positive electrode 54a and electrically connected to the back surface wiring 9 via the side wiring 1s.

樹脂絶縁層５１と、透明電極５３ａ，５３ｂのそれぞれの一部（発光素子１４が重ならない部位）と、透明電極５３ｃの周縁部と、を覆って、酸化珪素（ＳｉＯ2），窒化珪素（ＳｉＮx）等から成る絶縁層５５が配置されている。絶縁層５５上において、発光素子１４の搭載部と、遮光部材２５の配置部と、を除く部位に、ブラックマトリクス等から成る遮光層５６が配置されている。遮光層５６は、表示装置を平面視したときに発光素子１４の部位以外の部位が黒色等の暗色の背景色となるようにする目的で設けられる。 Silicon oxide (SiO 2 ) and silicon nitride (SiN) cover the resin insulating layer 51, a part of each of the transparent electrodes 53a and 53b (the portion where the light emitting element 14 does not overlap), and the peripheral edge of the transparent electrode 53c. An insulating layer 55 made of x) or the like is arranged. On the insulating layer 55, a light-shielding layer 56 made of a black matrix or the like is arranged at a portion other than the mounting portion of the light emitting element 14 and the arranging portion of the light-shielding member 25. The light-shielding layer 56 is provided for the purpose of allowing a portion other than the portion of the light emitting element 14 to have a dark background color such as black when the display device is viewed in a plan view.

しかしながら、図３〜図９に示す上記従来の表示装置においては、以下の問題点があった。基板１を平面視したときに、表示部１１の周囲に表示に寄与しない額縁部１ｇがあるために、図８、図９に示すように、額縁部１ｇにブラックマトリクス等から成る遮光部材２５を配置することによって額縁部１ｇを目立たなくしていた。しかしながら、基板１の厚み方向（基板１の主面に直交する方向）における基板１の主面からの遮光部材２５の高さが、最外周部にある発光素子１４の基板１の主面からの高さ位置よりも高いと、発光素子１４から放射された光の一部および外光が遮光部材２５で反射するために、コントラスト低下、画面の額縁が目立つことによる表示品位の低下の問題点があった。すなわち、遮光部材２５は黒色等の暗色系の色合いであったとしも、遮光部材２５の表面はある程度の艶があるために、遮光部材２５に入射した光は完全には吸収されず、光の一部が反射されるからである。 However, the conventional display devices shown in FIGS. 3 to 9 have the following problems. When the substrate 1 is viewed in a plan view, there is a frame portion 1g that does not contribute to the display around the display unit 11. Therefore, as shown in FIGS. 8 and 9, a light-shielding member 25 made of a black matrix or the like is attached to the frame portion 1g. By arranging it, 1 g of the frame portion was made inconspicuous. However, the height of the light-shielding member 25 from the main surface of the substrate 1 in the thickness direction of the substrate 1 (the direction orthogonal to the main surface of the substrate 1) is from the main surface of the substrate 1 of the light emitting element 14 on the outermost periphery. If it is higher than the height position, a part of the light radiated from the light emitting element 14 and the outside light are reflected by the light-shielding member 25, so that there are problems that the contrast is lowered and the display quality is lowered because the frame of the screen is conspicuous. there were. That is, even if the light-shielding member 25 has a dark color such as black, the light incident on the light-shielding member 25 is not completely absorbed because the surface of the light-shielding member 25 has a certain degree of luster. This is because part of it is reflected.

また、表示装置を製造する際に、多数の発光素子１４をそれぞれ凹部、貫通孔等に収容して配列させた治具を用い、その治具を基板１上で裏返して発光素子１４を基板１上の各搭載部にそれぞれ配置させる搭載方法、あるいは多数の発光素子１４を粘着シート上に配列させ、その粘着シートを基板１上で裏返して発光素子１４を基板１上の各搭載部にそれぞれ配置させる搭載方法、所謂転写法を採用することが多いが、遮光部材２５が障害となって最外周部の発光素子１４が搭載部に配置され難くなるという問題点があった。 Further, when manufacturing a display device, a jig in which a large number of light emitting elements 14 are housed and arranged in recesses, through holes, etc., respectively, is used, and the jig is turned over on the substrate 1 to place the light emitting element 14 on the substrate 1. A mounting method in which each of the above mounting portions is arranged, or a large number of light emitting elements 14 are arranged on an adhesive sheet, the adhesive sheet is turned over on the substrate 1, and the light emitting elements 14 are arranged in each mounting portion on the substrate 1. In many cases, a so-called transfer method is adopted, but there is a problem that the light-shielding member 25 becomes an obstacle and it becomes difficult for the light emitting element 14 at the outermost periphery to be arranged in the mounting portion.

例えば、図８に示す離隔幅Ｌ１（５５μｍ程度）である基板１の周縁部における額縁部１ｇの幅は２０μｍ〜５０μｍ程度であり、額縁部１ｇに遮光部材２５を配置すると、最外周部の発光素子１４と遮光部材２５との距離Ｌ１１は３５μｍ〜５μｍ程度となり、最外周部の発光素子１４から放射された光の一部が遮光部材２５によって容易に吸収される。また、転写法で製造する際に遮光部材２５が障害となりやすい。また、離隔幅Ｌ２（１３０μｍ程度）である基板１の周縁部における額縁部１ｇの幅は１１０μｍ程度であり、額縁部１ｇに遮光部材２５を配置すると、最外周部の発光素子１４と遮光部材２５との距離Ｌ２１は２０μｍ程度となり、最外周部の発光素子１４から放射された光の一部が遮光部材２５によって反射されやすい。また、転写法で製造する際に遮光部材２５が障害となりやすい。 For example, the width of the frame portion 1g at the peripheral edge portion of the substrate 1 having the separation width L1 (about 55 μm) shown in FIG. 8 is about 20 μm to 50 μm. The distance L11 between the element 14 and the light-shielding member 25 is about 35 μm to 5 μm, and a part of the light radiated from the light-emitting element 14 at the outermost periphery is easily absorbed by the light-shielding member 25. In addition, the light-shielding member 25 tends to be an obstacle during manufacturing by the transfer method. Further, the width of the frame portion 1g at the peripheral edge portion of the substrate 1 having a separation width L2 (about 130 μm) is about 110 μm, and when the light-shielding member 25 is arranged on the frame portion 1g, the light emitting element 14 and the light-shielding member 25 at the outermost peripheral portion are arranged. The distance L21 to and from the light emitting element L21 is about 20 μm, and a part of the light radiated from the light emitting element 14 at the outermost periphery is easily reflected by the light shielding member 25. In addition, the light-shielding member 25 tends to be an obstacle during manufacturing by the transfer method.

そこで、図１０に示すように、樹脂絶縁層５１の側面５１ｓが基板１の端１ｔに達しない構成とし、側面５１ｓと端１ｔの間の基板１上の部位に遮光部材２５を配置することによって、上記の問題点を解消することが考えられる。しかしながら、電極パッド２ｐおよび側面配線１ｓが遮光部材２５から露出しているために、表示装置を視認したときに電極パッド２ｐｃおよび側面配線１ｓが銀色、白色等の明るい色合いで視認されて目立つこととなる。その結果、表示部１１のコントラストが低下して表示品質が劣化するという問題点があった。 Therefore, as shown in FIG. 10, the side surface 51s of the resin insulating layer 51 does not reach the end 1t of the substrate 1, and the light-shielding member 25 is arranged at a portion on the substrate 1 between the side surface 51s and the end 1t. , It is conceivable to solve the above problems. However, since the electrode pad 2p and the side wiring 1s are exposed from the light-shielding member 25, the electrode pad 2pc and the side wiring 1s are visually recognized in bright colors such as silver and white and are conspicuous when the display device is visually recognized. Become. As a result, there is a problem that the contrast of the display unit 11 is lowered and the display quality is deteriorated.

本発明は、上記の問題点に鑑みて完成されたものであり、その目的は、表示部のコントラストが低下して表示品質が劣化することを抑えることであり、また転写法によって表示装置を製造する際に遮光部材が障害となって最外周部の発光素子が搭載部に配置され難くなることを抑えることである。 The present invention has been completed in view of the above problems, and an object of the present invention is to prevent the contrast of the display unit from being lowered and the display quality from being deteriorated, and to manufacture a display device by a transfer method. This is to prevent the light-shielding member from becoming an obstacle and making it difficult for the light emitting element on the outermost periphery to be arranged on the mounting portion.

The electrode pad, the side surface wiring, and the light-shielding member are arranged on the substrate between the end surface of the resin insulating layer and the end of the substrate.

また本発明の表示装置は、好ましくは、前記樹脂絶縁層は、複数のものが積層された積層構造とされている。 Further, the display device of the present invention preferably has a laminated structure in which a plurality of resin insulating layers are laminated.

本発明の発光装置は、基板と、前記基板上に搭載される発光素子と、前記基板上に配置され、前記発光素子に接続されて信号を入力する入力電極と、前記基板上の前記入力電極の外側に配置され、前記入力電極に電気的に接続される電極パッドと、前記電極パッドから前記基板の側面へ引き出されている側面配線と、前記基板上の前記入力電極の外側に配置された遮光部材と、を有する表示装置であって、前記入力電極と前記電極パッドと前記側面配線の前記基板からの高さを比較したときに、前記入力電極は前記電極パッド及び前記側面配線よりも高い位置にあり、前記電極パッド及び前記側面配線は、前記遮光部材によって覆われている構成であることから、以下の効果を奏する。表示装置を視認したときに電極パッド及び側面配線が銀色、白色等の明るい色合いで視認されて目立つことがなくなる。その結果、表示部のコントラストの低下を防いで表示品質を高品質のものとすることができる。また、遮光部材は、入力電極よりも低い位置にある、電極パッド及び側面配線を覆っているので、遮光部材の頂上の高さが入力電極の位置よりも高くなることを抑えることができる。その結果、発光素子から放射された光の一部が遮光部材によって反射されにくくなる。また、転写法によって表示装置を製造する際に遮光部材が障害となりにくくなるので、最外周部の発光素子を基板上に配置することが容易になる。 The light emitting device of the present invention includes a substrate, a light emitting element mounted on the substrate, an input electrode arranged on the substrate and connected to the light emitting element to input a signal, and the input electrode on the substrate. An electrode pad arranged outside the input electrode and electrically connected to the input electrode, side wiring drawn from the electrode pad to the side surface of the substrate, and arranged outside the input electrode on the substrate. In a display device having a light-shielding member, the input electrode is higher than the electrode pad and the side wiring when the heights of the input electrode, the electrode pad, and the side wiring from the substrate are compared. Since the electrode pad and the side surface wiring are located at the position and are covered with the light-shielding member, the following effects are obtained. When the display device is visually recognized, the electrode pads and the side wiring are visually recognized in bright colors such as silver and white, and are not noticeable. As a result, it is possible to prevent a decrease in the contrast of the display unit and improve the display quality. Further, since the light-shielding member covers the electrode pad and the side wiring located at a position lower than the input electrode, it is possible to prevent the height of the top of the light-shielding member from becoming higher than the position of the input electrode. As a result, a part of the light emitted from the light emitting element is less likely to be reflected by the light-shielding member. Further, since the light-shielding member is less likely to be an obstacle when the display device is manufactured by the transfer method, it becomes easy to arrange the light emitting element at the outermost periphery on the substrate.

本発明の表示装置は、前記基板上に複数の層状部材が積層されており、前記遮光部材と、前記複数の層状部材のうち最上層の層状部材と、の前記基板からの高さを比較したときに、前記遮光部材の頂上は前記最上層の層状部材の頂上以下の高さである場合、発光素子から放射された光の一部が遮光部材によって反射されることをより確実に抑えることができる。また、転写法によって表示装置を製造する際に遮光部材がより障害となりにくくなるので、最外周部の発光素子を基板上に配置することがより容易になる。 In the display device of the present invention, a plurality of layered members are laminated on the substrate, and the heights of the light-shielding member and the uppermost layered member of the plurality of layered members from the substrate are compared. Sometimes, when the top of the light-shielding member is at a height equal to or lower than the top of the uppermost layered member, it is possible to more reliably suppress that a part of the light emitted from the light emitting element is reflected by the light-shielding member. it can. Further, since the light-shielding member is less likely to be an obstacle when the display device is manufactured by the transfer method, it becomes easier to arrange the light emitting element at the outermost periphery on the substrate.

また本発明の表示装置は、前記最上層の層状部材は、前記発光素子の周囲に配置された遮光層である場合、発光素子から放射された光の大部分を遮光層で吸収することができ、表示部を視認したときに発光素子以外のものが目立たないようにすることができるとともにコントラストを向上させることができ、表示品質を良好なものとし得る。 Further, in the display device of the present invention, when the uppermost layered member is a light-shielding layer arranged around the light-emitting element, most of the light radiated from the light-emitting element can be absorbed by the light-shielding layer. It is possible to make things other than the light emitting element inconspicuous when the display unit is visually recognized, and to improve the contrast, so that the display quality can be improved.

また本発明の表示装置は、前記発光素子は、光放射部を有しており、前記光放射部と前記遮光層との前記基板からの高さを比較したときに、前記光放射部は前記遮光層の頂上よりも高い位置にある場合、発光素子から放射された光の一部が遮光層で反射されることを抑えて、コントラスト低下を抑えることができる。 Further, in the display device of the present invention, the light emitting element has a light emitting unit, and when the heights of the light emitting unit and the light shielding layer from the substrate are compared, the light emitting unit is said to be said. When it is located higher than the top of the light-shielding layer, it is possible to suppress a part of the light radiated from the light emitting element from being reflected by the light-shielding layer and suppress a decrease in contrast.

また本発明の表示装置は、前記基板と前記入力電極との間に樹脂絶縁層が配置されており、前記樹脂絶縁層は、その端面が前記基板の端に達しておらず、前記電極パッドと前記側面配線と前記遮光部材は、前記基板上において前記樹脂絶縁層の端面と前記基板の端との間に配置されている場合、樹脂絶縁層が入力電極の位置を高くする嵩上げ部材として機能し、また樹脂絶縁層の端面が遮光部材の配置位置を規定する堤防、仕切り壁等として機能するので、遮光部材が樹脂絶縁層上に乗り上げて遮光部材の頂上が入力電極よりも高い位置に誤配置されることを効果的に抑えることができる。 Further, in the display device of the present invention, a resin insulating layer is arranged between the substrate and the input electrode, and the end face of the resin insulating layer does not reach the end of the substrate, and the resin insulating layer and the electrode pad When the side surface wiring and the light-shielding member are arranged between the end face of the resin insulating layer and the edge of the substrate on the substrate, the resin insulating layer functions as a raising member for raising the position of the input electrode. In addition, since the end face of the resin insulating layer functions as a bank, a partition wall, etc. that defines the placement position of the light-shielding member, the light-shielding member rides on the resin insulating layer and the top of the light-shielding member is misplaced at a position higher than the input electrode. It can be effectively suppressed.

また本発明の表示装置は、前記樹脂絶縁層は、複数のものが積層された積層構造とされている場合、樹脂絶縁層が入力電極の位置を高くする嵩上げ部材として機能し、また樹脂絶縁層の端面が遮光部材の配置位置を規定する堤防、仕切り壁等として機能するという効果が向上する。 Further, in the display device of the present invention, when the resin insulating layer has a laminated structure in which a plurality of the resin insulating layers are laminated, the resin insulating layer functions as a raising member for raising the position of the input electrode, and the resin insulating layer also functions as a raising member. The effect that the end face of the light-shielding member functions as a dike, a partition wall, etc. that defines the arrangement position of the light-shielding member is improved.

以下、本発明の表示装置の実施の形態について、図面を参照しながら説明する。但し、以下で参照する各図は、本発明の表示装置の実施の形態における構成部材のうち、本発明の表示装置を説明するための主要部を示している。従って、本発明に係る表示装置は、図に示されていない回路基板、配線導体、制御ＩＣ，ＬＳＩ等の周知の構成部材を備えていてもよい。なお、本発明の表示装置の実施の形態を示す図１、図２において、図３〜図１０と同じ部位には同じ符号を付しており、それらの詳細な説明は省く。 Hereinafter, embodiments of the display device of the present invention will be described with reference to the drawings. However, each figure referred to below shows a main part for explaining the display device of the present invention among the constituent members in the embodiment of the display device of the present invention. Therefore, the display device according to the present invention may include well-known components such as a circuit board, a wiring conductor, a control IC, and an LSI (not shown in the figure). In FIGS. 1 and 2 showing the embodiment of the display device of the present invention, the same parts as those in FIGS. 3 to 10 are designated by the same reference numerals, and detailed description thereof will be omitted.

図１、図２は、本発明の表示装置について実施の形態の各種例を示す図である。これらの図に示すように、本発明の表示装置は、ガラス基板等から成る基板１と、基板１上に搭載される発光素子１４と、基板１上に配置され、発光素子１４に接続された信号を入力する入力電極としての正電極５４ａおよび負電極５４ｂと、基板１上の正電極５４ａおよび負電極５４ｂの外側に配置され、正電極５４ａに電気的に接続される電極パッド２ｐと、電極パッド２ｐから基板１の側面へ引き出されている側面配線１ｓと、基板１上の正電極５４ａおよび負電極５４ｂの外側に配置された遮光部材２５と、を有する表示装置であって、正電極５４ａおよび負電極５４ｂと電極パッド２ｐと側面配線１ｓの基板１からの高さを比較したときに、正電極５４ａおよび負電極５４ｂは電極パッド２ｐ及び側面配線１ｓよりも高い位置にあり、電極パッド２ｐ及び側面配線１ｓは、遮光部材２５によって覆われている構成である。 1 and 2 are diagrams showing various examples of embodiments of the display device of the present invention. As shown in these figures, the display device of the present invention is arranged on a substrate 1 made of a glass substrate or the like, a light emitting element 14 mounted on the substrate 1, and connected to the light emitting element 14. Positive electrodes 54a and negative electrodes 54b as input electrodes for inputting signals, electrode pads 2p arranged outside the positive electrodes 54a and negative electrodes 54b on the substrate 1 and electrically connected to the positive electrodes 54a, and electrodes. A display device having a side surface wiring 1s drawn from the pad 2p to the side surface of the substrate 1 and a light-shielding member 25 arranged outside the positive electrode 54a and the negative electrode 54b on the substrate 1, wherein the positive electrode 54a is provided. When the heights of the negative electrode 54b, the electrode pad 2p, and the side wiring 1s from the substrate 1 are compared, the positive electrode 54a and the negative electrode 54b are located higher than the electrode pad 2p and the side wiring 1s, and the electrode pad 2p The side wiring 1s and the side wiring 1s are covered with a light-shielding member 25.

上記の構成により、以下の効果を奏する。表示装置を視認したときに電極パッド２ｐ及び側面配線１ｓが銀色、白色等の明るい色合いで視認されて目立つことがなくなる。その結果、表示部１１のコントラストの低下を防いで表示品質を高品質のものとすることができる。また、遮光部材２５は、正電極５４ａおよび負電極５４ｂよりも低い位置にある、電極パッド２ｐ及び側面配線１ｓを覆っているので、遮光部材２５の頂上の高さが正電極５４ａおよび負電極５４ｂの位置よりも高くなることを抑えることができる。その結果、発光素子１４から放射された光の一部が遮光部材２５によって反射されにくくなり、また転写法によって表示装置を製造する際に遮光部材２５が障害となりにくくなるので、最外周部の発光素子１４を基板１上に配置することが容易になる。 The above configuration produces the following effects. When the display device is visually recognized, the electrode pad 2p and the side wiring 1s are visually recognized in bright colors such as silver and white, and are not noticeable. As a result, it is possible to prevent a decrease in the contrast of the display unit 11 and improve the display quality. Further, since the light-shielding member 25 covers the electrode pad 2p and the side wiring 1s located lower than the positive electrode 54a and the negative electrode 54b, the height of the top of the light-shielding member 25 is the positive electrode 54a and the negative electrode 54b. It can be suppressed that it becomes higher than the position of. As a result, a part of the light radiated from the light emitting element 14 is less likely to be reflected by the light-shielding member 25, and the light-shielding member 25 is less likely to be an obstacle when manufacturing the display device by the transfer method. It becomes easy to arrange the element 14 on the substrate 1.

本発明の表示装置において、発光素子１４としては、マイクロチップ型の発光ダイオード（ＬＥＤ）、モノリシック型の発光ダイオード、有機ＥＬ、無機ＥＬ、半導体レーザ素子等の自発光型のものであれば採用し得る。 In the display device of the present invention, as the light emitting element 14, any self-luminous element such as a microchip type light emitting diode (LED), a monolithic type light emitting diode, an organic EL, an inorganic EL, or a semiconductor laser element is adopted. obtain.

遮光部材２５は、額縁部１ｇが目立たないようにする目的、また基板１の側面に配置される側面配線１ｓを保護する目的で配置される。従って、遮光部材２５は基板１の側面に延出させて配置することが好ましい。また、複数の発光素子１４を搭載した基板１の複数を、同じ面上において縦横に配置するとともにそれらの側面同士を接着材等によって結合（タイリング）させることによって、複合型かつ大型の表示装置、所謂マルチディスプレイを製造する場合に、遮光部材２５が存在することによってタイリングの継ぎ目が目立ちにくくなる。 The light-shielding member 25 is arranged for the purpose of making the frame portion 1g inconspicuous and for the purpose of protecting the side wiring 1s arranged on the side surface of the substrate 1. Therefore, it is preferable that the light-shielding member 25 is arranged so as to extend to the side surface of the substrate 1. Further, by arranging a plurality of substrates 1 on which a plurality of light emitting elements 14 are mounted vertically and horizontally on the same surface and connecting (tiling) the side surfaces thereof with an adhesive or the like, a composite type and large-sized display device. In the case of manufacturing a so-called multi-display, the presence of the light-shielding member 25 makes the tiling seams less noticeable.

遮光部材２５は、黒色、黒褐色、濃褐色、濃青色、濃紫色等の暗色系のもので可視光を効率良く吸収し遮光する色合いのものであり、例えば透明な樹脂層中に暗色系の顔料、染料等を混入させて構成された遮光膜、または接着、粘着等によって設置されるシール状のもの、または接着、粘着等によって設置されるプラスチック等から成る枠状体などから構成される。この遮光部材２５によって、可視光の大部分を吸収して遮光することができる。 The light-shielding member 25 is a dark-colored material such as black, black-brown, dark brown, dark blue, or dark purple, and has a color that efficiently absorbs visible light and blocks light. For example, a dark-colored pigment in a transparent resin layer. , A light-shielding film formed by mixing dyes, etc., a seal-like material installed by adhesion, adhesion, etc., or a frame-like body made of plastic, etc., installed by adhesion, adhesion, etc. The light-shielding member 25 can absorb most of the visible light to block light.

遮光部材２５は、上記の遮光膜である場合、暗色系の顔料、染料等を混入させた未硬化の樹脂ペーストを、基板１上の額縁部１ｇに、塗布法、マスクを用いた印刷法、ローラー印刷法等によって塗布、印刷して配置し、熱硬化法、紫外線等の照射による光硬化法、光熱硬化法等によって硬化させることにより形成される。 When the light-shielding member 25 is the above-mentioned light-shielding film, an uncured resin paste mixed with a dark-colored pigment, a dye, or the like is applied to 1 g of a frame portion on the substrate 1 by a coating method or a printing method using a mask. It is formed by applying, printing, and arranging by a roller printing method or the like, and curing by a thermosetting method, a photocuring method by irradiating ultraviolet rays, a photocuring method, or the like.

遮光部材２５の幅は、額縁部１ｇの幅とほぼ同じである。例えば、幅の小さい方の額縁部１ｇ、例えば図８において基板１の上側の辺部にある額縁部１ｇ、の幅が２０μｍ〜５０μｍ程度であることから、幅の小さい方の額縁部１ｇに配置される遮光部材２５の幅は２０μｍ〜５０μｍ程度である。幅の大きい方の額縁部１ｇ、例えば図８において基板１の左側の辺部にある額縁部１ｇ、の幅が１１０μｍ程度であることから、幅の大きい方の額縁部１ｇに配置される遮光部材２５の幅は１１０μｍ程度である。 The width of the light-shielding member 25 is substantially the same as the width of the frame portion 1 g. For example, since the width of the smaller frame portion 1 g, for example, the frame portion 1 g on the upper side portion of the substrate 1 in FIG. 8 is about 20 μm to 50 μm, it is arranged in the smaller width frame portion 1 g. The width of the light-shielding member 25 to be formed is about 20 μm to 50 μm. Since the width of the wider frame portion 1 g, for example, the frame portion 1 g on the left side side of the substrate 1 in FIG. 8 is about 110 μm, the light-shielding member arranged on the wider frame portion 1 g. The width of 25 is about 110 μm.

また本発明の表示装置は、基板１上に複数の層状部材が積層されており、遮光部材２５と、複数の層状部材のうち最上層の層状部材と、の基板１からの高さを比較したときに、遮光部材２５の頂上は最上層の層状部材の頂上以下の高さであることが好ましい。図１の構成の場合、遮光部材２５の頂上の高さｈ１が、最上層の層状部材である遮光層５６の頂上の高さｈ３以下の高さであることが好ましい。この場合、発光素子１４から放射された光の一部が遮光部材２５によって反射されることをより確実に抑えることができる。また、転写法によって表示装置を製造する際に遮光部材がより障害となりにくくなるので、最外周部の発光素子を基板上に配置することがより容易になる。なお、複数の層状部材は、図１の構成の場合、樹脂絶縁層５１、絶縁層５５、遮光層５６であり、図２の構成の場合、樹脂絶縁層５１ａ，５１ｂ、絶縁層５５、遮光層５６である。 Further, in the display device of the present invention, a plurality of layered members are laminated on the substrate 1, and the heights of the light-shielding member 25 and the uppermost layered member among the plurality of layered members are compared with respect to the substrate 1. Occasionally, the top of the light-shielding member 25 is preferably at a height equal to or lower than the top of the uppermost layered member. In the case of the configuration of FIG. 1, the height h1 of the top of the light-shielding member 25 is preferably a height h3 or less of the height of the top of the light-shielding layer 56, which is the uppermost layered member. In this case, it is possible to more reliably suppress that a part of the light emitted from the light emitting element 14 is reflected by the light shielding member 25. Further, since the light-shielding member is less likely to be an obstacle when the display device is manufactured by the transfer method, it becomes easier to arrange the light emitting element at the outermost periphery on the substrate. In the case of the configuration of FIG. 1, the plurality of layered members are the resin insulating layer 51, the insulating layer 55, and the light-shielding layer 56, and in the case of the configuration of FIG. 2, the resin insulating layers 51a and 51b, the insulating layer 55, and the light-shielding layer 56. 56.

また本発明の表示装置は、最上層の層状部材は、発光素子１４の周囲に配置された遮光層５６であることが好ましい。この場合、発光素子１４から放射された光の大部分を遮光層５６で吸収することができ、表示部を視認したときに発光素子１４以外のものが目立たないようにすることができるとともにコントラストを向上させることができ、表示品質を良好なものとし得る。遮光層５６は、必ずしも最上層でなくてもよく、基板１の発光素子搭載面上に配置されていてもよい。 Further, in the display device of the present invention, the layered member of the uppermost layer is preferably a light-shielding layer 56 arranged around the light emitting element 14. In this case, most of the light radiated from the light emitting element 14 can be absorbed by the light shielding layer 56, so that when the display unit is visually recognized, anything other than the light emitting element 14 can be made inconspicuous and the contrast can be improved. It can be improved and the display quality can be improved. The light-shielding layer 56 does not necessarily have to be the uppermost layer, and may be arranged on the light emitting element mounting surface of the substrate 1.

また本発明の表示装置は、発光素子１４は、その上面等に光放射部１４ａを有しており、光放射部１４ａと遮光層２５との基板１からの高さを比較したときに、光放射部１４ａは遮光層２５の頂上よりも高い位置にあることが好ましい。この場合、発光素子１４から放射された光の一部が遮光層２５で反射されることを抑えて、コントラスト低下を抑えることができる。 Further, in the display device of the present invention, the light emitting element 14 has a light emitting portion 14a on its upper surface or the like, and when the heights of the light emitting portion 14a and the light shielding layer 25 from the substrate 1 are compared, the light is emitted. The radiation portion 14a is preferably located higher than the top of the light shielding layer 25. In this case, it is possible to suppress a part of the light radiated from the light emitting element 14 from being reflected by the light-shielding layer 25, and to suppress a decrease in contrast.

また、光放射部１４ａは発光素子１４の上面にあることが多いが、横断面でみたときに発光素子１４の内部にあってもよく、その場合光放射部１４ａの高さが遮光部材２５の頂上よりも高い位置にあってもよい。この場合、発光素子１４から放射された光の一部は、遮光部材２５で反射されにくくなるので、コントラスト低下、画面の額縁部が目立つことによる表示品位の低下を抑えることができる。 Further, although the light emitting portion 14a is often located on the upper surface of the light emitting element 14, it may be inside the light emitting element 14 when viewed in cross section. In that case, the height of the light emitting portion 14a is the light shielding member 25. It may be higher than the top. In this case, a part of the light radiated from the light emitting element 14 is less likely to be reflected by the light-shielding member 25, so that it is possible to suppress a decrease in contrast and a decrease in display quality due to the conspicuous frame portion of the screen.

正電極５４ａおよび負電極５４ｂが遮光部材２５の頂上以上の高さの位置にある（ｈ２≧ｈ１である）ことがより好ましく、この場合、発光素子１４から放射された光の一部が遮光部材２５によって反射されることをより確実に抑えることができ、また転写法によって表示装置を製造する際に遮光部材２５がより障害となりにくくなるので、最外周部の発光素子１４を基板１上に配置することがより容易になる。 It is more preferable that the positive electrode 54a and the negative electrode 54b are located at a height higher than the top of the light-shielding member 25 (h2 ≧ h1). In this case, a part of the light emitted from the light emitting element 14 is the light-shielding member. Since it is possible to more reliably suppress the reflection by the 25 and the light-shielding member 25 is less likely to be an obstacle when manufacturing the display device by the transfer method, the light emitting element 14 at the outermost periphery is arranged on the substrate 1. It will be easier to do.

また遮光部材２５は、基板１からの高さについて、基板１の発光素子１４が搭載される側の面（発光素子搭載面）からの頂上の高さｈ１が２μｍ〜１０μｍ程度である。また正電極５４ａおよび負電極５４ｂは、上記の通り基板１からの高さを比較したときに遮光部材２５の頂上以上の高さ位置にあることがより好ましく、正電極５４ａおよび負電極５４ｂの発光素子搭載面からの高さｈ２はｈ１と同程度であるか３μｍ程度高い。 The height h1 of the top of the light-shielding member 25 from the surface of the substrate 1 on which the light-emitting element 14 is mounted (the surface on which the light-emitting element is mounted) is about 2 μm to 10 μm. Further, the positive electrode 54a and the negative electrode 54b are more preferably located at a height above the top of the light-shielding member 25 when the heights from the substrate 1 are compared as described above, and the positive electrode 54a and the negative electrode 54b emit light. The height h2 from the element mounting surface is about the same as h1 or about 3 μm higher.

本発明の表示装置は、複数の発光素子１４がある場合に、それらのすべてについて正電極５４ａおよび負電極５４ｂが遮光部材２５の頂上以上の高さの位置にある（ｈ２≧ｈ１である）ことが好ましい。この場合、複数の発光素子１４から放射された光の一部が遮光部材２５によって反射することを抑えることができ、コントラスト低下を抑えることができる。さらには、複数の発光素子１４のすべてについて正電極５４ａおよび負電極５４ｂが同じ高さであることが良い。この場合、転写法によって表示装置を製造する際に、遮光部材２５が障害となることがなく、複数の発光素子１４のすべてをそれらの搭載部（正電極５４ａおよび負電極５４ｂ）上にほぼ同時に設置することができる。その結果、複数の発光素子１４のどれかが設置タイミングがずれることによって設置位置がずれやすくなることを抑えることができる。 In the display device of the present invention, when there are a plurality of light emitting elements 14, the positive electrode 54a and the negative electrode 54b are located at a height higher than the top of the light-shielding member 25 (h2 ≧ h1) for all of them. Is preferable. In this case, it is possible to suppress that a part of the light radiated from the plurality of light emitting elements 14 is reflected by the light-shielding member 25, and it is possible to suppress a decrease in contrast. Further, it is preferable that the positive electrode 54a and the negative electrode 54b have the same height for all of the plurality of light emitting elements 14. In this case, when the display device is manufactured by the transfer method, the light-shielding member 25 does not become an obstacle, and all of the plurality of light emitting elements 14 are placed on their mounting portions (positive electrode 54a and negative electrode 54b) substantially at the same time. Can be installed. As a result, it is possible to prevent the installation position of any of the plurality of light emitting elements 14 from being easily displaced due to the deviation of the installation timing.

また本発明の表示装置は、複数の発光素子１４がある場合に、それらのうち遮光部材２５に最も近い発光素子１４は、基板１からの高さを比較したときに基板１上のすべての部材のなかで最も高い位置にあることが好ましい。この場合、遮光部材２５に最も近い発光素子１４から放射された光の一部は、基板１上の他の部材によって反射されにくくなるので、コントラスト低下をより抑えることができる。また転写法によって表示装置を製造する際に基板１上の部材が障害となりにくくなるので、最外周部の発光素子１４をその搭載部に配置することがより容易になる。例えば、図１、図２に示すように、基板１上の最上部には遮光層５６があるが、遮光部材２５に最も近い発光素子１４が遮光層５６の頂上よりも高い位置にあることがよい。 Further, in the display device of the present invention, when there are a plurality of light emitting elements 14, the light emitting element 14 closest to the light shielding member 25 is all the members on the substrate 1 when the heights from the substrate 1 are compared. It is preferably in the highest position among them. In this case, a part of the light radiated from the light emitting element 14 closest to the light-shielding member 25 is less likely to be reflected by other members on the substrate 1, so that the decrease in contrast can be further suppressed. Further, since the member on the substrate 1 is less likely to be an obstacle when the display device is manufactured by the transfer method, it becomes easier to arrange the light emitting element 14 on the outermost peripheral portion on the mounting portion thereof. For example, as shown in FIGS. 1 and 2, there is a light-shielding layer 56 at the uppermost portion on the substrate 1, but the light emitting element 14 closest to the light-shielding member 25 may be located higher than the top of the light-shielding layer 56. Good.

また、複数の発光素子１４がある場合に、それらのすべてが基板１上のすべての部材のなかで最も高い位置にあることが好ましい。この場合、複数の発光素子１４から放射された光は、基板１上の他の部材によって反射されにくくなるので、コントラスト低下をさらに抑えることができる。さらには、複数の発光素子１４のすべてについて正電極５４ａおよび負電極５４ｂが同じ高さであることが良く、転写法によって表示装置を製造する際に、基板１上の他の部材が障害となることがなく、複数の発光素子１４のすべてをそれらの搭載部（正電極５４ａおよび負電極５４ｂ）上にほぼ同時に設置することができる。その結果、複数の発光素子１４のどれかが設置タイミングがずれることによって設置位置がずれやすくなることを抑えることができる。 Further, when there are a plurality of light emitting elements 14, it is preferable that all of them are at the highest position among all the members on the substrate 1. In this case, the light radiated from the plurality of light emitting elements 14 is less likely to be reflected by other members on the substrate 1, so that the decrease in contrast can be further suppressed. Further, it is preferable that the positive electrode 54a and the negative electrode 54b have the same height for all of the plurality of light emitting elements 14, and other members on the substrate 1 become obstacles when the display device is manufactured by the transfer method. All of the plurality of light emitting elements 14 can be installed on their mounting portions (positive electrode 54a and negative electrode 54b) at substantially the same time. As a result, it is possible to prevent the installation position of any of the plurality of light emitting elements 14 from being easily displaced due to the deviation of the installation timing.

また本発明の表示装置は、図１に示すように、基板１と正電極５４ａおよび負電極５４ｂとの間に樹脂絶縁層５１が配置されており、樹脂絶縁層５１は、その端面５１ｔが基板１の端１ｔに達しておらず、電極パッド２ｐと側面配線１ｓと遮光部材２５は、基板１上において樹脂絶縁層５１の端面５１ｔと基板１の端１ｔとの間に配置されていることが好ましい。この場合、樹脂絶縁層５１が正電極５４ａおよび負電極５４ｂの位置を高くする嵩上げ部材と機能し、また樹脂絶縁層５１の端面５１ｔが遮光部材２５の配置位置を規定する堤防、仕切り壁等として機能するので、遮光部材２５が樹脂絶縁層５１上に乗り上げて遮光部材２５の頂上が正電極５４ａおよび負電極５４ｂよりも高い位置に誤配置されることを効果的に抑えることができる。また、電極パッド２ｐが側面配線１ｓに近接しているので、それらの接続性が向上し、断線等の接続不良の発生を抑えることができる。 Further, in the display device of the present invention, as shown in FIG. 1, a resin insulating layer 51 is arranged between the substrate 1 and the positive electrode 54a and the negative electrode 54b, and the resin insulating layer 51 has an end face 51t of the substrate. The electrode pad 2p, the side wiring 1s, and the light-shielding member 25 are arranged on the substrate 1 between the end surface 51t of the resin insulating layer 51 and the end 1t of the substrate 1, not reaching the end 1t of 1. preferable. In this case, the resin insulating layer 51 functions as a raising member for raising the positions of the positive electrode 54a and the negative electrode 54b, and the end surface 51t of the resin insulating layer 51 serves as an embankment, a partition wall, or the like that defines the arrangement position of the light-shielding member 25. Since it functions, it is possible to effectively prevent the light-shielding member 25 from riding on the resin insulating layer 51 and erroneously arranging the top of the light-shielding member 25 at a position higher than the positive electrode 54a and the negative electrode 54b. Further, since the electrode pads 2p are close to the side wiring 1s, their connectivity is improved, and the occurrence of poor connection such as disconnection can be suppressed.

また本発明の表示装置は、樹脂絶縁層５１の端面５１ｔは、基板１の端１ｔ側に向かうに伴って厚みが薄くなる傾斜面とされており、遮光部材２５は、樹脂絶縁層５１の端面５１ｔに重なっていることが好ましい。この場合、樹脂絶縁層５１の端面５１ｔの長さが長くなる。その結果、遮光部材２５が樹脂絶縁層５１上に乗り上げて遮光部材２５の頂上が正電極５４ａおよび負電極５４ｂよりも高い位置に誤配置されることをより効果的に抑えることができる。すなわち、遮光部材２５を塗布法、印刷法等によって形成する際に、端面５１ｔが垂直面よりも長さが長い斜面であることから、遮光部材２５の発光素子１４側への侵入を効果的に阻止することができる。斜面とされた端面５１ｔの基板１の発光素子搭載面に対する傾斜角度は２０°〜７０°程度が良い。２０°未満では、樹脂絶縁層５１の端面５１ｔの長さ（幅）が長くなり額縁部１ｇが大きくなる傾向がある。７０°を超えると、端面５１ｔの長さが垂直面の長さに近くなるために、遮光部材２５の発光素子１４側への侵入を阻止する効果が低下しやすくなる傾向がある。 Further, in the display device of the present invention, the end surface 51t of the resin insulating layer 51 is an inclined surface whose thickness becomes thinner toward the end 1t side of the substrate 1, and the light-shielding member 25 is the end surface of the resin insulating layer 51. It is preferable that it overlaps with 51t. In this case, the length of the end face 51t of the resin insulating layer 51 becomes long. As a result, it is possible to more effectively prevent the light-shielding member 25 from riding on the resin insulating layer 51 and erroneously arranging the top of the light-shielding member 25 at a position higher than the positive electrode 54a and the negative electrode 54b. That is, when the light-shielding member 25 is formed by a coating method, a printing method, or the like, since the end surface 51t is a slope having a length longer than the vertical surface, the light-shielding member 25 effectively penetrates into the light emitting element 14 side. It can be stopped. The inclination angle of the end surface 51t, which is a slope, with respect to the light emitting element mounting surface of the substrate 1 is preferably about 20 ° to 70 °. If it is less than 20 °, the length (width) of the end face 51t of the resin insulating layer 51 tends to be long, and the frame portion 1g tends to be large. If it exceeds 70 °, the length of the end surface 51t becomes close to the length of the vertical surface, so that the effect of preventing the light-shielding member 25 from entering the light emitting element 14 side tends to be reduced.

また、樹脂絶縁層５１が複数の樹脂絶縁層を積層させた積層構造とされていてもよい。この場合、樹脂絶縁層５１が正電極５４ａおよび負電極５４ｂの位置を高くする嵩上げ部材として機能し、また樹脂絶縁層５１の端面５１ｔが遮光部材２５の配置位置を規定する堤防、仕切り壁等として機能するという効果が向上する。さらに、樹脂絶縁層５１が複数の樹脂絶縁層を積層させた積層構造とされており、図２の構成を採ることもできる。図２の場合、樹脂絶縁層５１ａ，５１ｂの２層であるが、３層以上であってもよい。下層である樹脂絶縁層５１ａの端面５１ａｔは基板１の端１ｔにほぼ達しているが、上層である樹脂絶縁層５１ｂの端面５１ｂｔは基板１の端１ｔに達していない。樹脂絶縁層５１ａ上において、樹脂絶縁層５１ｂの端面５１ｂｔと基板１の端１ｔとの間の部位に、電極パッド２ｐと側面配線１ｓと遮光部材２５が配置される。この場合、樹脂絶縁層５１の厚みをより厚くすることが容易になる。また、樹脂絶縁層５１ｂの厚みを樹脂絶縁層５１ａの厚みより厚くすることによって、遮光部材２５の高さが正電極５４ａおよび負電極５４ｂの高さよりも低くなるように調整することが容易になる。 Further, the resin insulating layer 51 may have a laminated structure in which a plurality of resin insulating layers are laminated. In this case, the resin insulating layer 51 functions as a raising member for raising the positions of the positive electrode 54a and the negative electrode 54b, and the end surface 51t of the resin insulating layer 51 serves as a dike, a partition wall, or the like that defines the arrangement position of the light-shielding member 25. The effect of functioning is improved. Further, the resin insulating layer 51 has a laminated structure in which a plurality of resin insulating layers are laminated, and the configuration shown in FIG. 2 can be adopted. In the case of FIG. 2, the resin insulating layers 51a and 51b are two layers, but may be three or more layers. The end surface 51at of the resin insulating layer 51a, which is the lower layer, substantially reaches the end 1t of the substrate 1, but the end surface 51bt of the resin insulating layer 51b, which is the upper layer, does not reach the end 1t of the substrate 1. On the resin insulating layer 51a, the electrode pad 2p, the side wiring 1s, and the light-shielding member 25 are arranged at a portion between the end surface 51bt of the resin insulating layer 51b and the end 1t of the substrate 1. In this case, it becomes easy to increase the thickness of the resin insulating layer 51. Further, by making the thickness of the resin insulating layer 51b thicker than the thickness of the resin insulating layer 51a, it becomes easy to adjust the height of the light-shielding member 25 to be lower than the heights of the positive electrode 54a and the negative electrode 54b. ..

なお、図２の構成において、樹脂絶縁層５１が１層であって、段差を有しており、段差から低い方の部位に電極パッド２ｐと側面配線１ｓと遮光部材２５が配置され、段差から高い方の部位に正電極５４ａおよび負電極５４ｂが配置されていてもよい。 In the configuration of FIG. 2, the resin insulating layer 51 is one layer and has a step, and the electrode pad 2p, the side wiring 1s, and the light-shielding member 25 are arranged at a portion lower than the step, and from the step. The positive electrode 54a and the negative electrode 54b may be arranged at the higher portion.

As shown in FIG. 8, for example, the light emission control unit 22 has a TFT 12 as a switch element for inputting a light emission signal to each of the light emission elements 14, and a level of the light emission control signal (a signal transmitted through the light emission control signal line 3). As a driving element for driving the light emitting element 14 with a current from a potential difference (light emitting signal) between a positive voltage (anode voltage: about 3 to 5V) and a negative voltage (cathode voltage: about -3V to 0V) according to (voltage). Includes TFT 13 and. A capacitive element is arranged on the connection line connecting the gate electrode and the source electrode of the TFT 13, and the capacitive element changes the voltage of the light emission control signal input to the gate electrode of the TFT 13 until the next rewriting (one frame). Period) Functions as a holding capacity to hold.
