  • Publication number: 20020057235
    Abstract: A display device includes a display panel and a flexible printed circuit board. The display panel includes a plurality of pixels which have an insulation substrate, a plurality of first electrodes disposed on the insulation substrate in a matrix form, a second electrode provided opposite to the first electrodes and an optical modulation layer held between the first and second electrodes, and driving circuits integrated on the insulation substrate to drive the pixels. A connecting portion of the printed circuit board is fixed on a main surface of the insulation substrate to supply electrical signals to the display panel. The flexible printed circuit board is provided on a non-display side of the display panel and a part of the other portion than the connecting portion is fixed on the display panel.

  • Patent number: 5666172
    Abstract: One side wall of a liquid crystal display device (11) having a surface iluminant light source (backlight) is formed by one side wall (521) of an outer frame (bezel cover) (500) and a vertical wall of a lamp cover (850). In this liquid crystal display device (11), the lower end of the side wall (521) of the outer frame (500) and the upper end of the cover (850) are provided with bent ends (853, 523) and these bent ends (853, 523) engage with each other. In this way it is possible to make the display than and lightweight while maintaining ample rigidity, Also, the liquid crystal panel (100) is not readily damaged by shocks from outside. Furthermore, replacement of the linear light source (811) is extremely easy.
