Abstract

PURPOSE:To enhance durability against temp. and humidity, by sealing a whole circumference contg. the junctions of cells consisting of plastic bases with a flexible plastic sheet. CONSTITUTION:Embodiments of plastics usable as a plastic base are polystyrene, polycarbonate, polyester, acrylic resin, epoxy resin, polysulfone, polyethersulfone, etc., and those of a flexible plastic sheet for covering and sealing the whole circumference contg. the junctions of cells are polymethyl methacrylate, polycarbonate, polyethylene terephthalate, etc., preferably having 50-500mum thickness. The sheet is covered by lamination, or dipping the cells in a soln. of this plastics and drying it, or the like method, thus permitting the cells using plastic bases intended for a thin type to be brought into practical use.

Description

【発明の詳細な説明】 本発明はプラスチ、り基板からなる液晶セルを更Ｋｆラ
スチ、クシート材で被覆してなる液晶表示装置に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid crystal display device in which a liquid crystal cell made of a plastic substrate is further covered with a Kf plastic or sheet material.

従来液晶表示装置において基板としてプラスチ、り基板
を用いた液晶表示セルは温度、湿度勢の耐久性が弱く、
例えば４！ｓ℃、湿度９０鳴で２０Ｏｈｒ−でセルの表
示劣化が認められ難点となっていた。In conventional liquid crystal display devices, liquid crystal display cells that use plastic or plastic substrates have poor durability against temperature and humidity changes.
For example, 4! Deterioration of the display of the cell was observed at s°C, humidity of 90°C, and 20 Ohr, which was a problem.

である。The present invention advantageously solves the disadvantages of liquid crystal display cells using such glass substrates, that is,! This is a sixth display device characterized in that a liquid crystal display cell made of a durable substrate is further covered and sealed around the entire circumference including at least the joint portion with a flexible glass sheet material.

このようにすることによシ、液晶表示装置として耐久性
