  • Liquid crystal display device including a spacer with adhesive between frame and a periphery of a principal surface of a substrate
    Patent number: 6515721
    Abstract: In a liquid crystal display device including a pair of substrates between which a liquid crystal layer is interposed, a semiconductor integrated circuit device provided at a periphery of a liquid crystal layer side surface of one substrate of the pair of substrates, a frame member having a display window and covering the substrates, and a spacer provided between the frame member and the periphery of the liquid crystal side surface of the one substrate, the present invention prevents the substrate from being cracked during assembly processes thereof and improves product quality thereof by protruding one side of the spacer toward another substrate of the pair of substrates partly, disposing the semiconductor integrated circuit device along a concave part of the spacer with respect to the another substrate, and providing an adhesive at a surface of the protruded part of the spacer opposite to the liquid crystal layer side surface.
