Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、液晶表示装置の構造に係り、特に熱圧着接続
片を使用した装置に好適な高信頼性な接続に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of a liquid crystal display device, and particularly to a highly reliable connection suitable for a device using a thermocompression bonding connection piece.

〔従来の技術〕[Conventional technology]

５３−２９４４０号）。As shown in FIG. 2, the liquid crystal display element 1 is mounted on the printed circuit board 2 with a spacer 6 interposed between the liquid crystal display element 1 and the printed circuit board 2, and the electric current between the liquid crystal display element 1 and the printed circuit board 2 is The connection is made using a connecting piece 3, and the connecting piece 3 is held down by a connecting piece presser 4 (Japanese Patent Publication No. 53-29440).

レーム５によりプリント基板２に固定されている。This connecting piece 3 is made of polyester or the like as shown in FIG. A conductor portion 32 is formed on the insulating base film 31 by printing or vapor deposition, and a thermocompression bonding material 33 is further formed. The connecting piece holder 4 is fixed to the printed circuit board 2 by a frame 5 as shown in FIG.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

上記従来技術では、熱圧着接続片３を使用する装置にお
いて比較的実装空間に自由度が有り剥れ防止のための接
続片押え４が熱圧着接続片３を液晶素子１のガラス基板
の端面に直接押しつけなかったためガラス基板端面で熱
圧着接続片３の導電部を切断することはなかったが、高
密度実装となり、空間に制約が生ずると上記導電の切断
という問題が発生する。In the above-mentioned conventional technology, the device using the thermocompression bonding connection piece 3 has a relatively flexible mounting space, and the connection piece presser 4 to prevent peeling is used to attach the thermocompression bonding connection piece 3 to the end surface of the glass substrate of the liquid crystal element 1. Since the glass substrate was not pressed directly, the conductive portion of the thermocompression bonding connection piece 3 was not cut at the end face of the glass substrate, but when high-density mounting is required and space is restricted, the problem of the conductive portion being cut occurs.

本発明の目的は上記不良を排除することにある。An object of the present invention is to eliminate the above defects.

〔問題点を解決するための手段〕[Means for solving problems]

上記目的は、熱圧着接続片３を押える接続片押え４がガ
ラス基板端面に対向する部分に逃げ溝を設はガラス基板
端面に接続片押え４が当らないようにすることにより達
成される。The above object is achieved by providing an escape groove in the portion of the connection piece presser 4 that presses down the thermocompression bonded connection piece 3 facing the end surface of the glass substrate so that the connection piece presser 4 does not come into contact with the end surface of the glass substrate.

〔作用〕[Effect]

接続片押えの構造がガラス基板端面に対向する部分に逃
げ溝を作りガラス基板端面と熱圧着接続片の間に空間を
生ぜしぬ力がかからない構造とすることにより接続片の
導電体部分に力がかからず断線の発生を防止することが
出来る。The structure of the connecting piece holder has an escape groove in the part facing the end surface of the glass substrate, which does not create a space between the end surface of the glass substrate and the thermocompression bonded connection piece, so that no force is applied to the conductor part of the connection piece. This prevents wire breakage from occurring.

〔実施例〕〔Example〕

以下、本発明の一実施例を第１図により説明する。接続
片押え４が液晶素子１の基板ガラス端面部分に対向する
位置に逃げ溝１０を設はフレーム５による圧力がガラス
基板端面に直接かからない様にする。このことによりガ
ラス基板端面での接続片３の導電体部分３２の切断がな
くなり信頼性が向上する。An embodiment of the present invention will be described below with reference to FIG. An escape groove 10 is provided at a position where the connecting piece presser 4 faces the end surface of the glass substrate of the liquid crystal element 1 so that the pressure from the frame 5 is not applied directly to the end surface of the glass substrate. This eliminates cutting of the conductor portion 32 of the connecting piece 3 at the end surface of the glass substrate, improving reliability.

〔発明の効果〕〔Effect of the invention〕

本発明によればガラス基板端面と接続片との間に圧力が
かからず接続片の導電体部分に傷を付けることがなく接
続の信頼性が向上する効果が有る。According to the present invention, no pressure is applied between the end face of the glass substrate and the connection piece, and the conductor portion of the connection piece is not damaged, thereby improving the reliability of the connection.
