本発明は液晶表示装置に係り、特に液晶素子をフｌｌン
ト基板に固定する正面パネルの爪とプリント基板のアー
ス電極との接続構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a liquid crystal display device, and more particularly to a connection structure between a claw on a front panel for fixing a liquid crystal element to a front board and a ground electrode on a printed circuit board.
従来、正面パネルの爪をプリント基板のアース電極に接
触させるものとして、例えば実公昭５８−３１１８８号
公報に示すものが知られている。Conventionally, there has been known a device for bringing the claws of the front panel into contact with the ground electrode of the printed circuit board, as shown in, for example, Japanese Utility Model Publication No. 58-31188.

アース電極５１こ接触する。なお、６はプリント基板２
の表面ｆこ形成された回路端子を示す。Due to this, the liquid crystal element 1 is fixed to the printed circuit board 2, and the claw 4a comes into contact with a ground electrode 51 formed on the back surface of the printed circuit board 2. In addition, 6 is the printed circuit board 2
A circuit terminal formed on the surface of the substrate is shown.
〔発明が解決、しようとする問題点〕 。[Problem that the invention attempts to solve].
上記従来例は、アース電極５に接触する爪４ａの部分は
、平坦状１Ｃ形成さ、れているの７ｖ１接触が不安定で
あり、長時間使扇している内曇こ爪部分が外側Ｅこ変形
してしまＣ〜、アース電極との接触が取れなくなるとい
う問題点があった。In the above conventional example, the part of the claw 4a that contacts the ground electrode 5 is formed in a flat shape 1C, and the contact with the claw 4a is unstable. This deformation caused the problem that it could no longer make contact with the ground electrode.
本発明の目的は、正面パネルの爪をアース電極に確実ｆ
こ接触させることができる液晶表示装置を提供すること
にある。The object of the present invention is to ensure that the claws on the front panel are connected to the ground electrode.
The object of the present invention is to provide a liquid crystal display device that can be brought into contact with the user.
上記目的は、正面パネルの爪のアース電極との接触面を
鋸歯状に形成することにより達成される。The above object is achieved by forming the contact surface of the claw of the front panel with the ground electrode into a sawtooth shape.
爪の鋸歯状がアース電極に食い込むので、確実ζこ接触
する。また長時間使用しても爪が外側に変形するのが防
止される。The serrations of the claws bite into the ground electrode, ensuring reliable contact. It also prevents the nails from deforming outward even after long-term use.

アース電極５との接触面は鋸歯状４ｂ番こ形成されてい
る。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Note that the same or equivalent members as in FIG. 3 are given the same numbers, and their explanations will be omitted. The contact surface of the claw 4a of the front panel 4 with the ground electrode 5 is serrated 4b.
そこで、爪４ａをプリント基板２＃こ保合させた時、鋸

４ａはアース電極５に確実ｌこ接触する。Therefore, when the claws 4a are held together with the printed circuit board 2, the peaks of the serrations 4b bite into the ground electrode 5, so that the claws 4a reliably contact the ground electrode 5.
本発明によれば、正面パネルがアース電極に確実に接続
されるので、信頼性が向上する。According to the present invention, since the front panel is reliably connected to the ground electrode, reliability is improved.
