交又または平行になるように配設する。Therefore, the picture electrode substrate 1.2 is placed opposite to the picture electrode 3.4 so that their arrangement directions cross each other, the periphery is sealed with a sealing material 5, and a liquid crystal 6 is placed inside, usually with a positive dielectric constant difference. A nematic liquid crystal having anisotropy is encapsulated in the encapsulation lower, and the encapsulation lower is sealed with a sealing material 8. Then, the picture electrode substrates 1 and 2
Polarizing plates 9 and IO are respectively disposed on the outer sides of the optical discs so that their polarization axes cross or are parallel to each other.

色むら、閾値むらが発生し、またシール材５の接着力が
不安定であるという問題があった。In the above conventional technology, the terminal side 1 which supplies a signal to the common electrode 4
The common electrode 4 is formed under the sealing material 5 of 1, and the sealing material 50 of the side 12 of the lower enclosure in which the liquid crystal 6 is enclosed.
The common electrode 4 is not formed below. For this reason, there was a gap difference between the terminal side 11 and the sealing port side 12, which caused problems such as uneven display color and threshold value, and unstable adhesive force of the sealing material 5.
本発明の目的は、色むら、閾値むら及びシール材の接着
力の不安定をなくシ、均一な表示が得られる液晶表示素
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 that eliminates color unevenness, threshold value unevenness, and instability of adhesive force of a sealing material, and provides a uniform display.
上記目的は、封入口側のシール材に対応した部分にダミ
ー用電極を形成することにより達成される。The above object is achieved by forming a dummy electrode in a portion corresponding to the sealing material on the side of the filling port.
封入口側にも端子側と同様に電極を形成することＫより
、端子側と封入口側とのギャップ差がなくなる。このた
め、端子側と封入口側での色むら、閾値むらがなくな抄
、均一な表示が可能となる。By forming electrodes on the filling port side in the same manner as on the terminal side, the gap difference between the terminal side and the filling port side is eliminated. Therefore, color unevenness and threshold value unevenness on the terminal side and the filling port side are eliminated, and uniform display can be achieved.
またギャップ差がないので、画電極基板をシールしてい
るシール材の接着力も安定する。Furthermore, since there is no gap difference, the adhesive strength of the sealing material that seals the picture electrode substrate is also stable.
以下、本発明の一実施例を第１図により説明する。なお

ダミー用電極１３が前記コモン電極４に接続しないで形
成されている。An embodiment of the present invention will be described below with reference to FIG. Note that the same or equivalent members as in FIG. 2 are given the same reference numerals, and their explanations will be omitted. A common electrode 4 is provided on the lower electrode substrate 2.
In addition, a dummy electrode 13 is also formed at a portion corresponding to the sealing material 5 on the filling port side 12 without being connected to the common electrode 4.
そこで、前記のようにコモン電極４とダミー用電極１３
とが形成された下側電極２と従来と同様に形成された上
電極基板１とを従来と同様の手法によって液晶表示素子
を組立る。Therefore, as mentioned above, the common electrode 4 and the dummy electrode 13
A liquid crystal display element is assembled by the same method as in the conventional method using the lower electrode 2 formed with the above and the upper electrode substrate 1 formed in the same manner as in the conventional method.
このように、端子側１１のシール材５の下にはコモン電

でギャップを均一に保つことができる。In this way, the common electrode 4 is formed under the sealing material 5 on the terminal side 11, and the dummy electrode 1 is also formed under the sealing port side 12.
3, it is possible to maintain a uniform gap between the terminal side 11 and the sealing port side 12.
また本実施例に示すように１ダミー用電極１３をコモン
電極４と接続しないととＫより、コモン電極４に与えら
れる信号に悪影響を与えることがない。Furthermore, as shown in this embodiment, unless the first dummy electrode 13 is connected to the common electrode 4, the signal given to the common electrode 4 will not be adversely affected.
本発明によれば、封入口側のシール材の下にダミー用電
