  • Patent number: 7636137
    Abstract: A metallic back case (40) arranged on the back side of a main liquid crystal panel (20) included in a double-sided display liquid crystal module has an opening (42) that corresponds to a sub liquid crystal panel (60). A resin frame (50) is removably fitted in the opening (42), and the sub liquid crystal panel (60) is fitted to the resin frame (50). Thus, the sub liquid crystal panel (60) is kept out of direct contact with the back case (40).

  • Patent number: 7554626
    Abstract: A liquid crystal display device characterized in that an illumination unit includes a substantially wedge-shaped light-guiding plate 5 being tilted such that plate thickness becomes thinner from one side edge toward the other side edge, a light source 41 disposed along the thicker plate surface of the light-guiding plate, lead wires 43, 44 of the light source, and a housing 7 that houses these parts, in which the light-guiding plate is installed such that a gap L2 between the backside 52 of the light-guiding plate and the bottom wall of the housing becomes larger as the plate thickness becomes thinner, and a portion of the lead wires resides in the gap L2 and the wires are arranged along the other side edge 54 of the light-guiding plate.

  • Publication number: 20060164860
    Abstract: A liquid crystal display device includes a light source and a light guide plate, and further includes, laid successively on top of the light guide plate, a diffusive sheet, a first and a second prism sheet having prism ridges thereof aligned in mutually perpendicular directions, a lower polarizing plate, a liquid crystal cell, and an upper polarizing plate. The first and second prism sheet has the prism ridges thereof aligned in a direction parallel or perpendicular to the row direction of the pixels. The lower polarizing plate has, laid successively downward below the liquid crystal cell, a first adhesive layer, a first transparent film, a polarizing film, and a second transparent film. The first adhesive layer contains a light-diffusing material.
