本発明は液晶表示素子に係り、特に液晶表示素子を組立
るときのプリント基板との位置合せを容易にすることが
できる液晶表示素子に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a liquid crystal display element, and more particularly to a liquid crystal display element that can be easily aligned with a printed circuit board when assembling the liquid crystal display element.
近年、液晶表示素子は大型化、高時分割化が進んでおり
、犀。デユーティなどが実用化されつつある。このよう
な液晶表示素子は画素が２００×６４０以上になってい
るので、端子数が１２８０本以上１こなり、端子ピッチ
は０．３ ｍ程度となっている。このように、端子数が
多く、かつ端子ピッチの小さい液晶表示素子をプリント
基板に実装することは、プリント基板との位置合せが非
常に困難である。In recent years, liquid crystal display elements have become larger and more time-divided. Duty etc. are being put into practical use. Since such a liquid crystal display element has pixels of 200×640 or more, the number of terminals is 1,280 or more, and the terminal pitch is about 0.3 m. As described above, when mounting a liquid crystal display element having a large number of terminals and a small terminal pitch on a printed circuit board, it is very difficult to align the liquid crystal display element with the printed circuit board.
従来、液晶表示素子とプリント基板との位置合せは、一
般的に端面部を使って行なっているが、前記のように端
子ピッチが小さくなると、この方法での位置合せは困難
である。Conventionally, alignment between a liquid crystal display element and a printed circuit board has generally been performed using an end face portion, but as the terminal pitch becomes smaller as described above, alignment using this method becomes difficult.
そこで、電極パターンと同時にフォトエツチングなどに
より位置合せマークを液晶表示素子とプリント基板の両

位置合せする方法が行なわれている。従来、前記位置合

。しかしながら、位置合せマークを端子部に付けると、
組立時に使用するコ木りタの影となり、組立がむづかし
くなる。また位置合せマークを液晶表示素子の内部に付
けた場合は、配向膜と位置合せマークのネナパターンの
屈折率が同様なため、位置合せマークが見えにくく位置
合せが容易でない。Therefore, a method is used in which an alignment mark is attached at the same location on both the liquid crystal display element and the printed circuit board by photoetching or the like at the same time as the electrode pattern, and alignment is performed using this alignment mark as a reference. Conventionally, the alignment mark is attached to a terminal portion or inside a liquid crystal display element. However, if you add alignment marks to the terminals,
It will shadow the Koki Rita used during assembly, making assembly difficult. Further, when the alignment mark is attached inside the liquid crystal display element, the alignment film and the alignment mark have similar refractive indexes, so the alignment mark is difficult to see and alignment is not easy.
本発明の目的は、位置合せマークが見易く、プリント基
板との位置合せが容易に行なえる液晶表示素子を提供す
ることにある。An object of the present invention is to provide a liquid crystal display element with easy-to-see alignment marks and easy alignment with a printed circuit board.
本発明は上記目的を達成するために、対向面に透明電極

けたことを特徴とする。In order to achieve the above object, the present invention provides a liquid crystal display element in which the peripheries of two electrode substrates having transparent electrodes formed on opposing surfaces are sealed with a sealing material, in which a part of the pattern of the sealing material is placed on the inner side. It is characterized by having terminal alignment marks for the liquid crystal display element and the printed circuit board on the outside of this part.
以下、本発明の一実施例を図により説明する。 Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
第１図には２つの実施例を同一＠匣内に図示した。In FIG. 1, two embodiments are shown in the same box.

ことにより、電極パターンとの位置精度を向上させるこ
とができる。In this way, the cord of the sealing material 3 is formed so that the part is on the inside, and the terminal alignment mark 5 is attached to the outside of this part, so that the terminal alignment mark 5 can be attached to a part other than the terminal part 4. It is possible to avoid the shadow of the connector used during assembly, and the alignment film inside the liquid crystal display element can be
There's no one in charge. Therefore, the terminal alignment mark 5 can be easily seen and alignment with the printed circuit board can be easily performed. Further, by forming the terminal alignment mark 5 at the same time as forming the electrode pattern, the positional accuracy with respect to the electrode pattern can be improved.
