  • Patent number: 7188989
    Abstract: The light guide plate 32 has a light receiving portion 36 on one side thereof to receive light emitted by the LED 24 and a flexible light guide body 35 for transforming the light received by the light receiving portion 36 into planar light. The light guide body 35 is arranged along the liquid crystal panel 23 and has a plurality of light scattering portions 30 arranged on an outer surface thereof in a propagation direction of light emitted by the LED 24. Since the light guide plate 32 comprises a flexible member and thus can be arranged in a curved shape conforming to the liquid crystal panel 23 having a curved surface portion, the curved surface portion of the liquid crystal panel 23 can be illuminated uniformly. Further, the provision of the light scattering portions 30 can enhance a light reception efficiency and light emission efficiency even if the light guide plate 32 is thin.
