  • Patent number: 7580103
    Abstract: An electro-optical device includes an electro-optical panel which displays an image on a display surface; a supporting member which supports the electro-optical device; and a flexible wiring substrate which is connected to the electro-optical device. The wiring substrate is bent such that at least a portion of a surface of the wiring substrate is opposite to a side surface of the supporting member, in regions other than a side of the wiring substrate connected to the electro-optical panel.
    Type: Grant

  • Patent number: 6283602
    Abstract: In a lighting device in which planar light is emitted from the planar light emitting surface of a light guide by using a point-source light, such as an LED, the emitted light having a uniform luminance level is obtained on the overall light emitting surface. The lighting device has a point-source light 18 for emitting light in a point-like form. A planar light guide 16 radiates light in a planar form from the planar light emitting surface 16a. A linear light guide 19 is disposed between the point-source light 18 and the planar light guide 16. The point-like light emitted from the point-source light 18 is converted into linear light by the linear light guide 19, and the linear light is guided into the planar light guide 16 through the light incident surface 16b. Since the linear light is incident on the planar light guide 16, the light having a uniform luminance level can be obtained on the overall light emitting surface 16a.
