Light source device with optical guiding member and planar light source device employing same |
摘要 |
A light source device (2) and a planar light source device (6) for a liquid crystal display device. The planar light source device includes a light source device and a light guide plate (67). The light source device includes a light-emitting element (21) and an optical guiding member (20) having a reflective surface. The reflective surface receives light rays emitted by the light-emitting element (21), and guiding the light rays out from a plurality of generally aligned through holes (23) defined in a front light-emitting surface (28) of the optical guiding member. The light guide plate has a light incident surface being adjacent to the light source device. The planar light source device can diminish greatly possible dark regions on the light-emitting surface of the light guide plate and provide uniform illumination for an LCD.
