〔産業上の利用分野〕
本発明は、背景照明としてエレクトロルミネッセンス（
ＥＬ）を使用する場合の液晶表示装置に関するものであ
る。[Detailed Description of the Invention] [Industrial Application Field] The present invention uses electroluminescence (
This invention relates to a liquid crystal display device when using an EL.
従来、ＥＬを仔し、かつ、液晶駆動用ドライバー等を実
装したフレキシブル基板を用いた透過型液晶表示装置に
おいては、ＥＬ自体を、液晶パネルへ両面接着テープ、
接菅剤等で固定していた。Conventionally, in a transmissive liquid crystal display device that uses an EL and a flexible substrate on which a driver for driving the liquid crystal is mounted, the EL itself is attached to the liquid crystal panel using double-sided adhesive tape,
It was fixed with glue etc.
しかし、前述の従来技術ではＥＬが固定されている為に
、寿命の短いＥＬを簡単に交換する事が出来なかった。However, in the prior art described above, since the EL is fixed, it is not possible to easily replace the EL, which has a short lifespan.
本発明は、ＥＬ単体のみを簡単に交換可能な、液晶表示
装置を提供することを目的とする。An object of the present invention is to provide a liquid crystal display device in which only the EL unit can be easily replaced.

ネルに、貼り付けることを特徴とする。The liquid crystal display device of the present invention includes an EL backlight and uses a flexible substrate on which a driver for driving the liquid crystal, etc. is mounted, and is characterized in that an EL guide plate is attached to the liquid crystal panel. .
本発明の上記の構成によれば、ＥＬを装着する場合に、
プラスチック製の案内板によって液晶表示Ｈａ内に案内
され、ＥＬが、プラスチック製の案内板により確実に固
定する事が出来る。According to the above configuration of the present invention, when mounting the EL,
The EL is guided into the liquid crystal display Ha by a plastic guide plate, and the EL can be securely fixed by the plastic guide plate.

た。A plastic EL guide plate 6 is located between the circuit board 2 that supplies signals and power to the liquid crystal panel 3 and the flexible substrate 1, and is fixed to the liquid crystal panel 3 with double-sided bone tape, adhesive, etc. ing. By inserting the EL 4 from the front direction under the liquid crystal panel 3 along the wall surface of the EL guide plate 6, the structure is easily removed.

に対して、強くなり、信頼性が向上した。FIG. 2 is a vertical cross-sectional view of a transmission type liquid crystal display device including an EL according to another embodiment of the present invention. By incorporating the function of the EL guide plate 60 into the exterior case 7, the number of parts can be eliminated and costs can be reduced. Furthermore, since double-sided adhesive tape or adhesives are not used, it is resistant to vibrations and shocks, and reliability is improved.

。[Effects of the Invention] As described above, according to the present invention, in the case of a transmission type liquid crystal display device that includes an EL, when the Ti degree of the EL decreases and it becomes necessary to replace it, it is possible to easily replace only the EL. Being replaceable has the great effect of making maintenance easier.

、衝撃に対する信頼性が大巾に向上した。In addition, when assembling a transmissive liquid crystal display device, since it can be mounted on a solid guide plate rather than a film-like EL board, positioning of each component is easy (man-hours can be considerably reduced. It is now possible to fix with screws, etc., greatly improving reliability against vibration and shock.
