産業上の利用分野
本発明は２枚以との基板を相互接続して得られる大型の
表示バネＮに関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a large display spring N obtained by interconnecting two or more substrates.
従来の技術
近年、液晶やＫＬを用いた表示パネルの進展は目ざまし

れている。しかしながら、液晶パネルにおいてもその構
造と大きさには制限があり。BACKGROUND OF THE INVENTION In recent years, display panels using liquid crystals and KL have made remarkable progress, and in particular, full-color displays using liquid crystals have been developed. However, there are limitations to the structure and size of liquid crystal panels as well.
現在でもせいぜい（２０Ｘ３０ｍ）のものが得られてい

ながら、この方法ではパネル間の継ぎ目が狭くならない
ため継ぎ目補正に特殊な方法を用いているのが現状であ
る。Even now, at most (20 x 30 m) can only be obtained. On the other hand, the demand for larger size is severe, and in order to meet this demand, we are trying to increase the size by combining (20 x 30 cm) liquid crystal panels. Currently, one panel is attached to a box containing a drive circuit, and this is used as a unit to form a large screen, for example, 8x8 panels. However, since this method does not narrow the seams between panels, a special method is currently used for seam correction.

発明が解決しようとする問題点
このような従来の構成では、第３図に示すごとくパネル
間の間隔が狭くできないと言う問題があった。Problems to be Solved by the Invention In such a conventional structure, as shown in FIG. 3, there was a problem in that the distance between the panels could not be narrowed.
本発明はこのような問題点を解決するもので。The present invention is intended to solve these problems.
基板間の接続を強固にし、かつ間隔を狭くすることを目
的としたものである。The purpose is to strengthen the connection between boards and narrow the gap between them.
問題点を解決するための手段
この問題点を解決するために本発明は、基板の電極端子
を含んで基板側面に溝を形成し、その溝に表面が導電性
である接続体を挿入して基板間を接続したものである。Means for Solving the Problem In order to solve this problem, the present invention forms a groove on the side surface of the substrate including the electrode terminal of the substrate, and inserts a connecting body whose surface is conductive into the groove. This is a connection between boards.
作用
この溝成により、電気的には接続体を介しているため、
確実かつ低抵抗接続が実現でき、基板間は溝と接続体で
決められる最低の間隔とすることが出来る。Due to this groove formation, electrical connection is made through the connection body, so
A reliable and low-resistance connection can be realized, and the distance between the boards can be the minimum determined by the groove and the connecting body.

半田を使用しても良い。In the figure, s1~1F is a liquid crystal panel, 2 is an electrode terminal, 3 is a groove formed on the side of the panel, 4 is a cylinder whose surface is a conductive connector, 6 is a seam, 6 is a reinforcing plate, 8
is a line indicating the boundary of the panel, and 9 is a conductive adhesive. As can be seen from FIG. 1, grooves 3 are formed on the sides of the liquid crystal panel. This groove 3 can be easily formed using a rotating grindstone. The diameter of the cylinder 4 should be twice the depth of the groove 3, that is, when the cylinder 4 is inserted into the groove 3, about the radius thereof should protrude. The size of the electrode terminal 2 is preferably larger than the groove 3. A cylinder 4 is inserted between the butted liquid crystal panels, and the cylinder 4 and the electrode terminal 2 are connected and fixed with a conductive adhesive 9. Solder may be used instead of the conductive adhesive 9.
このようにして接続された状態を第２図ム、Ｂに示す。The thus connected state is shown in FIGS.

６を使用するのが良い。According to the present invention, the seam 6 can be made as small as the cylinder 4 used. The width of the groove 3 can be reduced to about 60 μm by machining with a rotary grindstone. Further, it is preferable to use a reinforcing plate 6 such as a glass plate to increase the strength of the combined panel.
