  • Patent number: 8149365
    Abstract: A liquid crystal display apparatus includes a lower substrate, an upper substrate and a liquid crystal layer interposed between the lower substrate and the upper substrate. The lower substrate includes a display part for displaying image and a driving part for providing the display part with a driving signal. The upper substrate includes a common electrode and an insulating member that electrically insulates the common electrode from the driving part. The insulating member has a lower dielectric constant than the liquid crystal layer. Thus, a parasitic capacitance between the driving part and the common electrode is reduced to prevent malfunction of the driving part, and a display quality is enhanced.

  • Patent number: 8139180
    Abstract: On the side surface of an optical guide plate (104), an engaging protrusion (105) is formed for fixing the optical guide plate (104) on to a frame (101) by fitting the optical guide plate in a recessed portion formed on the frame. The light emitted from an LED (107) enters the optical guide plate (104) from a light-incident end surface and travels in the optical guide plate (104) while spreading in a fan-shape. The engaging protrusion (105) is formed outside the outgoing-angle range of the beam (109) spreading in the fan-shape, thereby preventing occurrence of bright line caused by reflection of light at the corner portion of the base of the engaging protrusion (105).
