  • Patent number: 5267066
    Abstract: In a liquid crystal display device having pixels arranged in a matrix form, light is allowed to pass or blocked depending upon whether or not a voltage is applied to electrodes each corresponding to the pixels, and the display operation is conducted by controlling the transmission/nontransmission of light. When a conductor or switching element connected to an electrode is broken, it is not possible to apply such a voltage to the respective electrode. Such a pixel is always at the light transmission display state, with the result that the pixel becomes a bright spot, thereby degrading the display quality. Therefore, a blocking piece for blocking light is disposed over the pixel which becomes a bright spot. This prevents the bright spot from appearing, thereby improving the display quality.

  • Patent number: 4247590
    Abstract: A semiconductor wafer is supported by a supporting plate via adhesive in some steps of fabricating a semiconductor device. The supporting plate is a porous ceramic plate impregnated with or painted with resin such as epoxy resin, silicone resin and polyimide varnish. The porous ceramic supporting plate has a low thermal conductivity to ensure stable bonding operation.
