Description

この発明は、液晶表示装置、有機ＥＬ表示装置、プラズマ表示装置等の表示装置に関し、特に小型パネル設計における狭額縁化に関するものである。   The present invention relates to a display device such as a liquid crystal display device, an organic EL display device, and a plasma display device, and more particularly to a narrow frame in a small panel design.

従来、シール材の塗布または印刷工程において、表示パネルごとに個別に画素領域を囲むようにシールを配置し、その後、スクライブ工程でシールとシールとの間を切って基板を切り出すようにした表示装置がある（例えば、特許文献１参照）。   2. Description of the Related Art Conventionally, in a sealing material application or printing process, a seal is arranged so as to individually surround a pixel region for each display panel, and then a substrate is cut out between the seal and the seal in a scribing process. (For example, refer to Patent Document 1).

特開平１１−２３７６２１号公報JP-A-11-237621

しかしながら、上述した先行技術では、表示パネル毎に個別に画素領域を囲むようにシールを２重に配置し、２重のシール間に表示パネルのスクライブ位置を設けて、基板を切り出すようにしているので、マザーガラス内のパネル数が少なくならざるを得なかった。   However, in the above-described prior art, a double seal is provided so as to individually surround a pixel region for each display panel, and a scribe position of the display panel is provided between the double seals to cut out the substrate. Therefore, the number of panels in the mother glass had to be reduced.

この発明は上述した点に鑑みてなされたもので、パネル設計時の狭額縁化を図ることができる表示装置を得ることを目的とする。   The present invention has been made in view of the above-described points, and an object thereof is to obtain a display device capable of narrowing the frame when designing a panel.

この発明に係る表示装置は、マザーガラス内に、各表示パネル毎に個別に画素領域を囲み、液晶層を閉じ込めるように第１シールと、前記第１シールと離隔するようにその外郭に第２シールとを備える表示装置であって、前記第１及び第２シールは、閉ループであり、前記第２シールの縦方向の辺は、隣接する表示パネル同士で共有させ、かつ共有される第２シールは、共有されない両側のシール幅の倍の幅を有し、前記第２シールの横方向の辺は、隣接する表示パネルと離隔して備えることを特徴とする。

The display device according to the present invention includes a first seal so as to enclose a pixel region individually for each display panel in the mother glass and confine the liquid crystal layer, and a second outer portion so as to be separated from the first seal. The first and second seals are closed loops, and the vertical sides of the second seals are shared between adjacent display panels and are shared. Has a double width of the seal width on both sides that are not shared, and the lateral side of the second seal is provided apart from an adjacent display panel.

この発明によれば、隣接する表示パネル同士のシールを共有化することで、パネル設計時の狭額縁化を図ることができ、マザーガラスから取り出せる表示パネルを多くすることも可能となる。   According to the present invention, by sharing the seal between adjacent display panels, it is possible to narrow the frame when designing the panel, and it is also possible to increase the number of display panels that can be removed from the mother glass.

図１は、この発明の実施の形態に係る表示装置を説明するためのもので、マザーパネルの一部を切り出した平面図である。図１に示すように、マザーガラス１内の各表示パネル２毎に個別に画素領域を囲むようにシール３が設けられるが、隣接する表示パネル２同士のシール３ａは共有化させて印刷または塗布されている。なお、マザーガラス１の横方向にはタブ（引出電極）が存在するので、シール３ｂは共有化されてない。   FIG. 1 is a plan view of a mother panel cut out for explaining a display device according to an embodiment of the present invention. As shown in FIG. 1, a seal 3 is provided so as to individually surround a pixel region for each display panel 2 in the mother glass 1, but the seal 3 a between adjacent display panels 2 is shared and printed or applied. Has been. In addition, since the tab (extraction electrode) exists in the horizontal direction of the mother glass 1, the seal | sticker 3b is not shared.

図２は、マザーガラス１から各表示パネル２をスクライブする工程を説明する図である。また、図３は、図２のＡ−Ａ’断面図である。図２及び図３に示すように、スクライブ工程で共有したシール３ａをスクライブ位置としてシール３ａに沿ってシール３ａの半分を切ることにより表示パネルを取り出すことができる。なお、図３において、４は、上部基板と下部基板との間に介在される画素領域の液晶層を示す。また、両側のシール３ａの幅が中央部のシール３ａの半分になっているのは、スクライブ工程によりシール３ａの本来の幅が半分を切られているためである。   FIG. 2 is a diagram illustrating a process of scribing each display panel 2 from the mother glass 1. FIG. 3 is a cross-sectional view taken along the line A-A ′ of FIG. 2. As shown in FIGS. 2 and 3, the display panel can be taken out by cutting half of the seal 3 a along the seal 3 a with the seal 3 a shared in the scribing process as a scribe position. In FIG. 3, reference numeral 4 denotes a liquid crystal layer in a pixel region interposed between the upper substrate and the lower substrate. The width of the seal 3a on both sides is half that of the center seal 3a because the original width of the seal 3a is cut by half by the scribing process.

従って、上述した実施の形態によれば、隣接する表示パネル２のシール３ａを共有化することで、表示パネル設計時の狭額縁化が容易になり、パネル配置を工夫すればマザーガラス１から取り出せる表示パネル２を多くすることができ、マザーガラス１の有効利用を図ることができる。また、シール３ａを共有化した分、スクライブ工程における切り出し数も少なくすることができる。   Therefore, according to the above-described embodiment, by sharing the seal 3a of the adjacent display panel 2, it becomes easy to narrow the frame when designing the display panel, and it can be taken out from the mother glass 1 if the panel arrangement is devised. The number of display panels 2 can be increased, and the mother glass 1 can be effectively used. In addition, since the seal 3a is shared, the number of cutouts in the scribe process can be reduced.

なお、上述した実施の形態は、液晶表示装置の適用例を示したものであるが、この発明は、有機ＥＬ表示装置やプラズマ表示装置等にも適用でき、表示パネル設計時の狭額縁化を図る表示装置が得られる。   Although the above-described embodiment shows an application example of a liquid crystal display device, the present invention can also be applied to an organic EL display device, a plasma display device, and the like, and narrows the frame when designing a display panel. A display device is obtained.
