〔発明の利用分野〕
本発明は液晶表示素子に係り、特に液晶表示素子を構成
する電極基板上に形成された金属膜配線を保護する保護
膜の形成構造に関する。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 structure for forming a protective film that protects metal film wiring formed on an electrode substrate constituting a liquid crystal display element.
液晶表示素子は、周知の如く、２枚の電極基板の周囲を
シール材でシールし、内部に液晶材料を封入してなる。As is well known, a liquid crystal display element is made up of two electrode substrates whose peripheries are sealed with a sealant and a liquid crystal material is sealed inside.
前記電極基板上には金属膜配線が形成され、前記金属膜
配線を保護膜で覆っている。A metal film wiring is formed on the electrode substrate, and the metal film wiring is covered with a protective film.
従来の液晶表示素子の外部端子部分の構造は、第１図に
示すように、電極基板１上に金属膜配線２を形成し、前
記金属膜配線２の外部端子３の部分を除いて金属膜配線
２上に８ｉ０．などの保護膜４を形成してなる。As shown in FIG. 1, the structure of the external terminal portion of a conventional liquid crystal display element is such that a metal film wiring 2 is formed on an electrode substrate 1, and a metal film is formed on the metal film wiring 2 except for the external terminal 3. 8i0. on wiring 2. A protective film 4 such as the following is formed.
このように、外部端子３の部分は導通を取るために保護
［４を付けていないので、外部端子３の金属膜配線が端
の方からはがれてくるという問題点があった。As described above, since the external terminal 3 part is not provided with the protection [4] to ensure continuity, there is a problem in that the metal film wiring of the external terminal 3 peels off from the end.
本発明の目的は、金属膜配線のはがれが生じない液晶表
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 in which peeling of metal film wiring does not occur.

発明の実施例〕
以下、本発明の一実施例を第２図により説明する。なお
、第１図と同じ部材には同一符号を付し、その説明を省
略する。保護膜４は、外部端子３の周囲に少し重なるよ
うに形成してなる。In order to achieve the above object, the present invention seals the periphery of two electrode substrates with a sealing material, seals a liquid crystal material inside,
In a liquid crystal display element in which a metal film wiring is formed on the electrode substrate and the metal film wiring except for an external terminal portion of the metal film wiring is covered with a protective film, the protective film is slightly disposed around the external terminal. Features:
Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to FIG. Note that the same members as in FIG. 1 are given the same reference numerals, and their explanations will be omitted. The protective film 4 is formed around the external terminal 3 so as to slightly overlap it.
このように、外部端子３の周囲は保護膜４によって覆わ
れているので、外部端子３のエツチング境界面が露出す

頼性が向上する。As is clear from the above description, according to the present invention, two
sealing the periphery of the electrode substrate with a sealing material, sealing a liquid crystal material inside, forming metal film wiring on the electrode substrate,
In a liquid crystal display element in which the metal film wiring except for the external terminal portion of the metal film wiring is covered with a protective film, the protective film is formed so as to slightly overlap the external terminal, so that the metal film wiring Peeling of the liquid crystal display element is prevented, and the reliability of the liquid crystal display element is improved.
