A plurality of second electrodes 13b are formed in a predetermined pattern, an overcoat layer 14b is formed thereon, and an alignment film 16b is further formed thereon. Further, a polarizing plate 17b as an optical element is attached to the outer surface of the substrate material 12b by, for example, sticking.

In the case of a reflective layer-incorporated transflective panel, a reflective layer can be provided on the inner surface of the substrate material 12b on the liquid crystal layer side.

基板素材12a及び12bは、例えば、ガラス等といった硬質な光透過性材料や、プラスチック等といった可撓性を有する光透過性材料等によって所定形状、例えば長方形状や正方形状に形成される。また、第1電極13a及び第2電極13bは、例えば、ITO(Indium Tin Oxide)等といった透明導電材料によって1000Å程度の厚さに形成され、オーバーコート層14a及び14bは、例えば、酸化珪素、酸化チタン又はそれらの混合物等によって800Å程度の厚さに形成され、そして配向膜16a及び16bは、例えば、ポリイミド系樹脂によって800Å程度の厚さに形成される。   The substrate materials 12a and 12b are formed in a predetermined shape, for example, a rectangular shape or a square shape, using, for example, a hard light-transmitting material such as glass, or a flexible light-transmitting material such as plastic. The first electrode 13a and the second electrode 13b are formed with a thickness of about 1000 mm by a transparent conductive material such as ITO (Indium Tin Oxide), for example, and the overcoat layers 14a and 14b are made of, for example, silicon oxide, oxide Titanium or a mixture thereof is formed to a thickness of about 800 mm, and the alignment films 16a and 16b are formed to a thickness of about 800 mm by a polyimide resin, for example.

第1電極13aは、図1に示すように、複数の直線パターンを互いに平行に配列することによって、いわゆるストライプ状に形成される。一方、第2電極13bは、上記第1電極13aに交差するように複数の直線パターンを互いに平行に配列することによって、やはりストライプ状に形成される。これらの電極13aと電極13bとがドットマトリクス状に交差する複数の点が、像を表示するための画素を形成する。そして、それらの複数の画素によって区画形成される領域が、文字等といった像を表示するための表示領域となる。   As shown in FIG. 1, the first electrode 13 a is formed in a so-called stripe shape by arranging a plurality of linear patterns in parallel with each other. On the other hand, the second electrode 13b is also formed in a stripe shape by arranging a plurality of linear patterns parallel to each other so as to intersect the first electrode 13a. A plurality of points where these electrodes 13a and 13b intersect in a dot matrix form a pixel for displaying an image. An area defined by the plurality of pixels is a display area for displaying an image such as a character.

以上のようにして形成された第1基板9a及び第2基板9bのいずれか一方の液晶側表面には、図2に示すように、複数のスペーサ18が分散され、さらにいずれか一方の基板の液晶側表面にシール材11が、例えば印刷等によって図1に示すように枠状に設けられ、さらにそのシール材11の一部に液晶注入口11aが形成される。   As shown in FIG. 2, a plurality of spacers 18 are dispersed on the liquid crystal side surface of one of the first substrate 9a and the second substrate 9b formed as described above. A sealing material 11 is provided on the liquid crystal side surface in a frame shape as shown in FIG. 1 by, for example, printing, and a liquid crystal injection port 11 a is formed in a part of the sealing material 11.

両基板9a及び9bの間には、図2に示すようにスペーサ18によって保持される均一な寸法、例えば5μm程度の間隙、いわゆるセルギャップが形成され、液晶注入口11a(図1参照)を通してそのセルギャップ内に液晶19が注入され、その注入の完了後、液晶注入口11aが樹脂等によって封止される。   As shown in FIG. 2, a uniform dimension held by the spacer 18, for example, a gap of about 5 μm, a so-called cell gap, is formed between the substrates 9a and 9b, and this is passed through the liquid crystal injection port 11a (see FIG. 1). Liquid crystal 19 is injected into the cell gap, and after the injection is completed, the liquid crystal injection port 11a is sealed with resin or the like.

図1において、第1基板9aは第2基板9bの外側へ張り出す基板張出し部9cを有し、第1基板9a上の第1電極13aはその基板張出し部9cへ直接に延び出て配線21aとなっている。また、第2基板9bは第1基板9aの外側へ張り出す基板張出し部9dを有し、第2基板9b上の第2電極13bはその基板張出し部9へ直接に延び出て配線21bとなっている。   In FIG. 1, the first substrate 9a has a substrate overhanging portion 9c that protrudes to the outside of the second substrate 9b, and the first electrode 13a on the first substrate 9a directly extends to the substrate overhanging portion 9c to form the wiring 21a. It has become. Further, the second substrate 9b has a substrate overhanging portion 9d that protrudes outside the first substrate 9a, and the second electrode 13b on the second substrate 9b extends directly to the substrate overhanging portion 9 to become a wiring 21b. ing.

各電極13a及び13b、それらから延びる各配線21a及び21bは、実際には極めて狭い間隔で多数本がそれぞれの基板9a及び9bの表面全域に形成されるが、図1では構造を分かり易く示すために実際の間隔よりも広い間隔でそれらの電極等を模式的に図示し、さらに一部の電極の図示は省略してある。また、液晶が封入される領域内に形成される電極13a及び13bは、直線状に形成されることに限られず、適宜の文字、図形等といったパターンとして形成されることもある。   In reality, a large number of electrodes 13a and 13b and wirings 21a and 21b extending from them are formed over the entire surface of each of the substrates 9a and 9b at an extremely narrow interval, but FIG. 1 shows the structure in an easy-to-understand manner. These electrodes and the like are schematically shown at intervals wider than the actual intervals, and some of the electrodes are not shown. In addition, the electrodes 13a and 13b formed in the region where the liquid crystal is sealed are not limited to being formed in a straight line, and may be formed as a pattern such as an appropriate character or figure.

図1において、基板張出し部9c及び9dには、それぞれ、導電接続部材として作用するTCP(Tape Carrier Package)22a及び22bが異方性導電接着要素、例えばACF(Anisotropic Conductive Film:異方性導電膜)23によって接続される。   In FIG. 1, TCP (Tape Carrier Package) 22a and 22b acting as conductive connecting members are respectively attached to substrate projecting portions 9c and 9d, which are anisotropic conductive adhesive elements such as ACF (Anisotropic Conductive Film). ) 23.

ACF23は、周知の通り、一対の端子間を異方性を持たせて電気的に一括接続するために用いられる導電性のある高分子フィルムであって、例えば図2に示すように、熱可塑性又は熱硬化性の樹脂フィルム24の中に多数の導電粒子26を分散状態で含ませることによって形成される。   As is well known, the ACF 23 is a conductive polymer film that is used to electrically connect a pair of terminals with anisotropy and is electrically connected. For example, as shown in FIG. Alternatively, it is formed by including a large number of conductive particles 26 in a dispersed state in the thermosetting resin film 24.

図1において、TCP22a及び22bは、TAB技術を用いて構成されたIC構造体であって、例えば、配線27が形成されたFPC(Flexible Printed Circuit)28に液晶駆動用IC29a及び29bをそれぞれボンディング、例えばギャングボンディングして形成される。符号30a及び30bは、制御基板上の内部領域端子34a,34bとの間で電気的な接続をとるための端子を示している。   In FIG. 1, TCPs 22a and 22b are IC structures configured using TAB technology. For example, liquid crystal driving ICs 29a and 29b are bonded to an FPC (Flexible Printed Circuit) 28 in which wirings 27 are formed, respectively. For example, it is formed by gang bonding. Reference numerals 30a and 30b denote terminals for electrical connection with the internal region terminals 34a and 34b on the control board.

ACF23を挟んで基板張出し部9cとTCP22aとを熱圧着、すなわち加熱下で加圧することにより、TCP22aを基板張出し部9cに接着すると共に、TCP22aの配線27と基板張出し部9c上の配線21aとの間において単一方向の導電性を持つ接続を実現する。また、基板張出し部9dとTCP22bとの間に関しても同様の接着及び導電接続を実現する。   The substrate overhanging portion 9c and the TCP 22a are sandwiched between the ACF 23 by thermocompression bonding, that is, the pressure is applied under heating, so that the TCP 22a is bonded to the substrate overhanging portion 9c, and the TCP 27a wiring 27 and the wiring over the substrate overhanging portion 9c To achieve a unidirectional conductive connection between them. Further, the same adhesion and conductive connection are realized between the substrate overhanging portion 9d and the TCP 22b.

以上のように構成された液晶パネル2に関して、液晶駆動用IC29a又は29bによって第1電極13a又は第2電極13bのいずれか一方に対して行ごとに走査電圧を印加し、さらにそれらの電極の他方に対して表示画像に基づいたデータ電圧を印加することにより、各画素位置の液晶層に両電圧の差電圧を印加する。光が液晶層を通過するとき、上記の差電圧が印加された各画素部分で光が変調され、この光が光出射側の偏光板を通過する結果、基板9a又は9bの外側、本実施形態の場合は基板9aの外側に文字、数字等といった像が表示される。   With respect to the liquid crystal panel 2 configured as described above, a scanning voltage is applied to each of the first electrode 13a or the second electrode 13b for each row by the liquid crystal driving IC 29a or 29b, and the other of the electrodes is also applied. By applying a data voltage based on the display image to the liquid crystal layer, a voltage difference between the two voltages is applied to the liquid crystal layer at each pixel position. When the light passes through the liquid crystal layer, the light is modulated in each pixel portion to which the above-described differential voltage is applied, and as a result of the light passing through the polarizing plate on the light emitting side, the outside of the substrate 9a or 9b, this embodiment In this case, an image such as letters and numbers is displayed outside the substrate 9a.

導光体3の光取込み面側に設けられるLED基板6は、高さの低い両脇の裾部6aと、それらの裾部6a間に掛け渡された高さの高い梁部6bとによって形成され、発光素子である複数のLED(Light Emitting Diode)31がその梁部6bの長手方向に亘って適宜の間隔を開けて実装される。梁部6bの底部には所定間隔をもって切欠き、すなわち凹部37が設けられ、上記複数のLED31は、それらの凹部37を挟む位置関係で設けられる。LED基板6の裾部6aには端子32が形成され、LED基板6の内部又は表面には、それらの端子32、LED31及び必要に応じて設けられるその他の電子部品(図示せず)をつなげるための配線(図示せず)が形成される。   The LED substrate 6 provided on the light receiving surface side of the light guide 3 is formed by a skirt 6a on both sides having a low height and a beam 6b having a high height spanned between the skirts 6a. Then, a plurality of LEDs (Light Emitting Diodes) 31 that are light emitting elements are mounted at appropriate intervals along the longitudinal direction of the beam portion 6b. The bottom of the beam portion 6 b is notched with a predetermined interval, that is, a recess 37 is provided, and the plurality of LEDs 31 are provided in a positional relationship with the recess 37 interposed therebetween. Terminals 32 are formed on the skirt 6a of the LED board 6, and the terminals 32, LEDs 31 and other electronic components (not shown) provided as needed are connected to the inside or the surface of the LED board 6. Wiring (not shown) is formed.

LED基板6は、図1に示すように、導光体3の非光出射面側からフレーム4又は導光体3に装着される。この装着は、ネジや接着剤等といった特別な固着手段を用いて行うこともできるし、それに代えて、例えば、導光体3とフレーム4との間に形成した開口(図示せず)にLED基板6の裾部6aを挿入してはめ込むことによって達成することもできる。   As shown in FIG. 1, the LED substrate 6 is attached to the frame 4 or the light guide 3 from the non-light emitting surface side of the light guide 3. This mounting can be performed by using a special fixing means such as a screw or an adhesive. Instead, for example, an LED (not shown) formed between the light guide 3 and the frame 4 is connected to the LED. This can also be achieved by inserting and fitting the skirt 6a of the substrate 6.

LED基板6の裾部6aがフレーム4又は導光体3に装着された状態で、LED基板6の梁部6bは導光体3の側面、すなわち光取込み面に対向する位置に配置され、これにより、その梁部6bに実装されたLED31が導光体3の光取込み面に対向して配置される。この状態は、図2の断面構造を見ることによって明らかに理解できる。   In a state where the skirt portion 6a of the LED substrate 6 is mounted on the frame 4 or the light guide 3, the beam portion 6b of the LED substrate 6 is disposed at a position facing the side surface of the light guide 3, that is, the light capturing surface. Thus, the LED 31 mounted on the beam portion 6 b is disposed to face the light capturing surface of the light guide 3. This state can be clearly understood by looking at the cross-sectional structure of FIG.

図1において、制御基板7は、例えばガラスエポキシ樹脂等といった非可撓性の材料によって形成され、その裏面側には制御回路33、内部領域端子34a及び34b、そして辺端部端子36が設けられる。これらの要素は図示しない配線パターンを介して互いに電気的に接続される。制御回路33は、液晶パネル2の液晶駆動用IC29a,29bの動作を制御したり、LED31の点灯動作を制御したり、あるいは、本液晶装置1が用いられる電子機器、例えば携帯電話機、携帯情報端末機等の動作を制御する。   In FIG. 1, the control board 7 is made of an inflexible material such as glass epoxy resin, for example, and a control circuit 33, internal region terminals 34a and 34b, and side edge terminals 36 are provided on the back side thereof. . These elements are electrically connected to each other through a wiring pattern (not shown). The control circuit 33 controls the operation of the liquid crystal driving ICs 29a and 29b of the liquid crystal panel 2, controls the lighting operation of the LED 31, or an electronic device in which the liquid crystal device 1 is used, such as a mobile phone or a portable information terminal. Control the operation of the machine.

また、内部領域端子34aは、液晶パネル2から延びる一方のTCP22aの端子30aが接続される端子である。また、内部領域端子34bは、液晶パネル2から延びるもう一方のTCP22bの端子30bが接続される端子である。また、制御基板7のうちLED基板6が接続される辺端部には、複数の凸部38が形成され、そしてこれらの凸部38の両脇に必然的に開口39が形成される。   The internal region terminal 34a is a terminal to which the terminal 30a of one TCP 22a extending from the liquid crystal panel 2 is connected. The internal region terminal 34b is a terminal to which the terminal 30b of the other TCP 22b extending from the liquid crystal panel 2 is connected. In addition, a plurality of convex portions 38 are formed on the side end portion of the control substrate 7 to which the LED substrate 6 is connected, and openings 39 are inevitably formed on both sides of the convex portions 38.

制御基板7の2つの隅部には、それぞれ、穴40a及び40bが設けられる。
一方の穴40aは円形に形成され、他方の穴40bは一部が外部へ開放する形状に形成されている。制御基板7は、LED基板6が装着された状態のフレーム4又は導光体3に対して、導光体3の非光出射面側から装着される。このとき、図3(a)に示すように、制御基板7に設けられた穴40a及び40bが導光体3に設けられた突起10,10にはめ込まれ、これにより、導光体3に対する制御基板7の相対的な位置が常に一定の位置に決められる。
Holes 40a and 40b are provided in two corners of the control board 7, respectively.
One hole 40a is formed in a circular shape, and the other hole 40b is formed in a shape that is partially open to the outside. The control board 7 is attached from the non-light emitting surface side of the light guide 3 to the frame 4 or the light guide 3 on which the LED board 6 is attached. At this time, as shown in FIG. 3A, the holes 40 a and 40 b provided in the control board 7 are fitted into the protrusions 10 and 10 provided in the light guide 3, thereby controlling the light guide 3. The relative position of the substrate 7 is always fixed.

制御基板7側の穴40a及び40bの一方、本実施形態の場合は穴40bは外部へ開放する形状となっているので、それらの穴40a及び40bを突起10へはめ込む際の作業は簡単に行うことができる。   One of the holes 40a and 40b on the control board 7 side, in the case of this embodiment, the hole 40b has a shape that opens to the outside. Therefore, the work when the holes 40a and 40b are fitted into the protrusion 10 is easily performed. be able to.

導光体3への制御基板7の装着も、導光体3へのLED基板6の装着と同様に、ネジや接着剤等といった特別の固着手段を用いて行うこともできるし、あるいは、フレーム4の適所に固定用の突起(図示せず)を設けておき、その突起を用いて制御基板7を止めることによって達成できる。また、必ずしもそのような固着手段を使用することなく、単に、制御基板7を導光体3の上に載置するだけでも良い。この場合でも、突起10,10と穴40a,40bとのはめ合わせにより、導光体3に対する制御基板7の位置は常に一定の位置に保持されてずれることはない。   The mounting of the control board 7 to the light guide 3 can be performed using a special fixing means such as a screw or an adhesive as in the case of the mounting of the LED board 6 to the light guide 3 or a frame. This can be achieved by providing a fixing protrusion (not shown) at an appropriate position 4 and stopping the control board 7 using the protrusion. Further, the control board 7 may simply be placed on the light guide 3 without necessarily using such fixing means. Even in this case, the position of the control board 7 with respect to the light guide 3 is always held at a fixed position by the fitting of the protrusions 10 and 10 and the holes 40a and 40b, and does not shift.

以上のようにして制御基板7が支持部材としての導光体3に装着されると、制御基板7の凸部38がLED基板6の凹部37に嵌合した状態で、LED基板6が制御基板7の厚さ方向Z−Zへ張り出すようにして、LED基板6と制御基板7とが互いに組み付けられる。このとき、各LED31は制御基板7の凸部38の両脇に必然的に形成される開口39の中に収容される。   When the control board 7 is attached to the light guide 3 as a support member as described above, the LED board 6 is in the state in which the convex part 38 of the control board 7 is fitted in the concave part 37 of the LED board 6. The LED board 6 and the control board 7 are assembled to each other so as to project in the thickness direction ZZ of FIG. At this time, each LED 31 is accommodated in an opening 39 inevitably formed on both sides of the convex portion 38 of the control board 7.

LED基板6と制御基板7とが互いに組み付けられたとき、LED基板6の端子32と制御基板7の辺端部端子36は互いに位置的に一致する位置関係となって互いに接触する。そして、端子32と端子36との当該接触部分を導電接続処理、例えば、半田付け処理することにより、LED基板6が電気的且つ機械的に制御基板7に接続されて1つのユニットとしての照明用光源基板が形成される。   When the LED board 6 and the control board 7 are assembled to each other, the terminals 32 of the LED board 6 and the side edge terminals 36 of the control board 7 are in contact with each other in a positional relationship that coincides with each other. The LED board 6 is electrically and mechanically connected to the control board 7 by conducting a conductive connection process, for example, a soldering process, on the contact portion between the terminal 32 and the terminal 36. A light source substrate is formed.

フレーム4又は導光体3に装着された状態のLED基板6と制御基板7との接続部分の制御基板7の表面には、図2に示すように、電気絶縁性の遮蔽テープ46を設けておくのが望ましい。この遮蔽テープ46の働きにより、フラックス等といった不要物が開口39から侵入することを防止でき、さらに端子32,36等とTCP22a等との間でショートが発生することを防止できる。   As shown in FIG. 2, an electrically insulating shielding tape 46 is provided on the surface of the control board 7 where the LED board 6 attached to the frame 4 or the light guide 3 and the control board 7 are connected. It is desirable to leave. The function of the shielding tape 46 can prevent unwanted materials such as flux from entering through the opening 39, and can further prevent a short circuit from occurring between the terminals 32, 36 and the TCP 22a.

図1において、液晶パネル2は、その像表示面が外側に来るような状態で支持部材としての導光体3に装着される。このとき、一方のTCP22bは、その先端がフレーム4と導光体3との間に形成される略長方形の空間K(すなわち、導光体の切り欠け部K)を図1の上下方向へ通るように折り曲げられる。こうして液晶パネル2が導光体3の光出射面上に支持された後、一方のTCP22aはフレーム4に設けた切り欠き部42を通して制御基板7の裏側へ折り曲げられ、そして図2に示すように、その先端端子30aが制御基板7の裏面に形成された内部領域端子34aに導電接続処理、例えば半田付け処理によって接続される。   In FIG. 1, the liquid crystal panel 2 is mounted on a light guide 3 as a support member in a state where the image display surface is on the outside. At this time, one of the TCPs 22b passes through a substantially rectangular space K formed between the frame 4 and the light guide 3 (that is, the notch K of the light guide) in the vertical direction in FIG. It is bent as follows. After the liquid crystal panel 2 is supported on the light emitting surface of the light guide 3 in this way, one TCP 22a is bent to the back side of the control board 7 through a notch 42 provided in the frame 4, and as shown in FIG. The tip terminal 30a is connected to the internal region terminal 34a formed on the back surface of the control board 7 by conductive connection processing, for example, soldering processing.

他方、図1において、もう一方のTCP22bは、同様にして、導光体3及びフレーム4を通って制御基板7の裏側へ折り曲げられ、その先端端子30bが制御基板7の裏面に形成された内部領域端子34bに、例えば半田付け処理によって接続される。   On the other hand, in FIG. 1, the other TCP 22 b is similarly bent through the light guide 3 and the frame 4 to the back side of the control board 7, and the tip terminal 30 b is formed on the back side of the control board 7. The region terminal 34b is connected by, for example, a soldering process.

この時、空間Kの幅(すなわち、長手方向の長さ)は、TCP22bの幅(すなわち、基板張り出し部9dの長辺方向と同一方向の長さ)にほぼ等しくなっているので、TCP22bが空間Kを通ることにより、TCP22bは、導光体3に対して、幅方向W(すなわち、基板張り出し部9dの長辺方向と同一方向)に位置が決められることになる。同様に、切り欠き部42の幅(すなわち、基板張り出し部9cの長辺方向と同一方向の長さ)は、TCP22aの幅(すなわち、基板張り出し部9cの長辺方向と同一方向の長さ)にほぼ等しくなっているので、TCP22aが切り欠き部42を通ることで、TCP22aは、導光体3に対して、幅方向W(すなわち、基板張り出し部9cの長辺方向と同一方向)に位置が決められることになる。   At this time, the width of the space K (that is, the length in the longitudinal direction) is substantially equal to the width of the TCP 22b (that is, the length in the same direction as the long side direction of the substrate overhanging portion 9d). By passing K, the position of the TCP 22b is determined in the width direction W (that is, the same direction as the long side direction of the substrate overhanging portion 9d) with respect to the light guide 3. Similarly, the width of the cutout portion 42 (that is, the length in the same direction as the long side direction of the substrate overhanging portion 9c) is the width of the TCP 22a (that is, the length in the same direction as the long side direction of the substrate overhanging portion 9c). Since the TCP 22a passes through the cutout portion 42, the TCP 22a is positioned in the width direction W (that is, in the same direction as the long side direction of the substrate protruding portion 9c) with respect to the light guide 3. Will be decided.

すなわち、導光体3に対して、ボス10,10と穴40a,40bにより制御基板7の装着位置が決められると、導光体3に対する端子34a、34bの位置も決まる。そして、導光体3に液晶パネル2を装着すると、TCP22a、22bも幅方向Wについてそれぞれ位置決めされる。よって、TCP22a、22bと、端子34a、34bとを半田付けなどで接続する時には、端子34a,34bは、導光体3に対しては、それぞれ幅方向Wにはほぼ位置決めがされているので、幅方向Wのアライメント作業は極めて容易となる。   That is, when the mounting position of the control board 7 is determined by the bosses 10 and 10 and the holes 40a and 40b with respect to the light guide 3, the positions of the terminals 34a and 34b with respect to the light guide 3 are also determined. When the liquid crystal panel 2 is attached to the light guide 3, the TCPs 22a and 22b are also positioned in the width direction W, respectively. Therefore, when connecting the TCPs 22a and 22b and the terminals 34a and 34b by soldering or the like, the terminals 34a and 34b are substantially positioned in the width direction W with respect to the light guide 3, respectively. The alignment operation in the width direction W is extremely easy.

以上により、図1に分解して示した液晶装置1が図2に示すように組み付けられて完成する。この液晶装置1によれば、図1に示すように、制御基板7の穴40a及び40bを支持部材としての導光体3と一体な突起10,10にはめ込むことにより、導光体3に対する制御基板7の装着位置が常に一定位置に決められる。そして、このときの作業は単に穴40a,40bを突起10,10にはめ込むという極めて単純な作業で済み、制御基板7と導光体3とを目視によって位置決めするという不正確で面倒な作業をしなくて済むので、作業性が非常に高い。   Thus, the liquid crystal device 1 disassembled and shown in FIG. 1 is assembled and completed as shown in FIG. According to the liquid crystal device 1, as shown in FIG. 1, the holes 40a and 40b of the control board 7 are fitted into the projections 10 and 10 integrated with the light guide 3 as a support member, thereby controlling the light guide 3. The mounting position of the substrate 7 is always determined to be a fixed position. The work at this time is an extremely simple work of simply fitting the holes 40a and 40b into the protrusions 10 and 10, and the inaccurate and troublesome work of positioning the control board 7 and the light guide 3 by visual observation. Since it is not necessary, workability is very high.

そして、導光体3に対する制御基板7の装着位置が常に一定位置に決められることにより、制御基板7に対してその後に行われる種々の処理、例えば、TCP22a,22bの端子30a,30bを制御基板7の端子34a,34bに半田付けする処理等を位置精度良く行うことができる。   Since the mounting position of the control board 7 with respect to the light guide 3 is always determined to be a fixed position, various processes performed on the control board 7, such as the terminals 30a and 30b of the TCPs 22a and 22b, are controlled by the control board. 7 can be performed with high positional accuracy.

図3(b)は本発明に係る電気光学装置の他の実施形態の主要断面構造を示している。この実施形態も本発明を液晶装置に適用した場合の実施形態であり、その液晶装置の全体的な構成は図1に示した液晶装置1と同じである。図3(b)に示す実施形態が図3(a)に示した先の実施形態と異なる点は、導光体3に設ける突起10に改変を加えたことである。
(Second Embodiment)
FIG. 3B shows a main cross-sectional structure of another embodiment of the electro-optical device according to the invention. This embodiment is also an embodiment when the present invention is applied to a liquid crystal device, and the overall configuration of the liquid crystal device is the same as that of the liquid crystal device 1 shown in FIG. The embodiment shown in FIG. 3B is different from the previous embodiment shown in FIG. 3A in that the protrusion 10 provided on the light guide 3 is modified.

図3(a)に示す実施形態では、制御基板7に設けた穴40a及び40bよりも小さい外径の円錐形状によって突起10を形成したが、図3(b)に示す本実施形態では、円筒部43の先端に円錐部44を形成した形状の突起20を用いている。また、図3(a)に示す先の実施形態では制御基板7に設ける一方の穴40bを外部へ開放する形状に形成したが、本実施形態では制御基板7に設ける穴40a及び40bをいずれも円形状に形成した。   In the embodiment shown in FIG. 3A, the protrusion 10 is formed by a conical shape having an outer diameter smaller than the holes 40a and 40b provided in the control board 7, but in the present embodiment shown in FIG. A protrusion 20 having a shape in which a conical portion 44 is formed at the tip of the portion 43 is used. Further, in the previous embodiment shown in FIG. 3A, one hole 40b provided in the control board 7 is formed to be open to the outside. However, in this embodiment, both the holes 40a and 40b provided in the control board 7 are provided. It was formed in a circular shape.

本実施形態では、制御基板7の穴40a及び40bを導光体3の突起20,20へはめ込み、さらに適宜の圧力で押し付ける。すると、穴40a,40bは突起20の先端円錐部44を通過して円錐部43へ入り込む。この結果、制御基板7は突起20の先端円錐部44の底面大径部によって導光体3へ向けて押さえ付けられ、位置ズレしないようにしっかりと保持される。   In the present embodiment, the holes 40a and 40b of the control board 7 are fitted into the protrusions 20 and 20 of the light guide 3 and further pressed with an appropriate pressure. Then, the holes 40 a and 40 b pass through the tip cone portion 44 of the protrusion 20 and enter the cone portion 43. As a result, the control board 7 is pressed toward the light guide 3 by the large diameter portion of the bottom surface of the tip cone portion 44 of the protrusion 20 and is firmly held so as not to be displaced.

The present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to the embodiments, and various modifications can be made within the scope of the invention described in the claims.

例えば、図1の実施形態では、導光体3を支持部材として用いたが、液晶装置の中には導光体を使用しない構造のものがあり、そのような液晶装置では導光体3以外の部材が支持部材として用いられる。また、図1の液晶装置1では、フレーム4を支持部材として用いることもできる。   For example, in the embodiment of FIG. 1, the light guide 3 is used as the support member. However, some liquid crystal devices have a structure that does not use the light guide, and in such a liquid crystal device, other than the light guide 3. These members are used as support members. In the liquid crystal device 1 of FIG. 1, the frame 4 can also be used as a support member.

また、図1に示す実施形態では、液晶パネル2から2個、すなわち複数個のTCP22a及び22b、すなわち複数個の導電接続部材が延び出る場合を例示したが、液晶装置の種類によっては1個の導電接続部材が液晶パネルから延び出る場合もある。本発明はそのような導電接続部材が1個だけである液晶装置に対しても適用できる。   In the embodiment shown in FIG. 1, the case where two liquid crystal panels 2, that is, a plurality of TCPs 22 a and 22 b, that is, a plurality of conductive connecting members extend, is illustrated. In some cases, the conductive connecting member extends from the liquid crystal panel. The present invention can also be applied to a liquid crystal device having only one such conductive connecting member.

(The invention's effect)

本発明に係る電気光学装置及びその製造方法並びに電子機器によれば、制御基板の穴を導光体等といった支持部材の突起にはめ込むことにより、支持部材に対する制御基板の装着位置が常に一定位置に決められる。そして、このときの作業は単に穴を突起にはめ込むという極めて単純な作業で済み、制御基板と支持部材とを目視によって位置決めするという不正確で面倒な作業をしなくて済むので、作業性が非常に高い。   According to the electro-optical device, the manufacturing method thereof, and the electronic apparatus according to the invention, the mounting position of the control board with respect to the support member is always fixed by inserting the hole of the control board into the protrusion of the support member such as the light guide. It is decided. And the work at this time is a very simple work of simply fitting the hole into the protrusion, and it is not necessary to perform the inaccurate and troublesome work of positioning the control board and the support member by visual observation, so that the workability is very high. Very expensive.

そして、支持部材に対する制御基板の装着位置が常に一定位置に決められることにより、制御基板に対してその後に行われる種々の処理、例えば、FPC、TCP等といった導電接続部材の端子を制御基板の端子に半田付けする処理等を位置精度良く行うことができる。   Since the mounting position of the control board with respect to the support member is always determined to be a fixed position, various processing performed on the control board, for example, terminals of conductive connection members such as FPC, TCP, etc. are connected to the terminals of the control board. It is possible to perform a process of soldering on the surface with high positional accuracy.
