Document Type and Number:
Japanese Patent JPH11508708
Kind Code:
A
Abstract:
A liquid crystal display (LCD) having an active area for display of information and an inactive area adjacent the active area. The inactive area includes a pressure relief region for relieving pressure generated within the cell, thereby minimizing the effects of pressure variation in the active area. The display is comprised of two substrates, at least one of which is flexible, which are joined at their peripheries. A plurality of spacer members placed between the substrates insures a uniform gap between the substrates in the active area. The spacer members are preferably attached to both of the substrates in the active area, but to at most one of the substrates in the inactive area. The pressure relief region serves to relieve pressure within the display (usually caused by temperature changes) by flexure of the flexible substrate, thereby eliminating distortions within the active area. The flexure of the flexible substrate is enhanced by thinning the substrate in the pressure relief region, or by the incorporation of an edge spacer member which serves to prevent attachment of the spacer members to both of the substrates in the pressure relief region.
