Illumination device and liquid crystal display apparatus
First Claim
1. An illumination device for illuminating a liquid crystal panel having a frame area and an effective display area surrounded by the frame area, the illumination device comprising:
- a light source for emitting light;
an optical conductor including a light incident surface on which light emitted by the light source is allowed to be incident, a light output surface from which the light is allowed to be output, and a projection projecting from the light incident surface; and
a light scattering section for scattering light, the light scattering section including an engaging portion which is engageable with the projection;
wherein the optical conductor and the light scattering section are located such that an end of the projection of the optical conductor is located outside the effective display area of the liquid crystal panel.

Abstract
An illumination device for illuminating a liquid crystal panel having a frame area and an effective display area surrounded by the frame area includes a light source for emitting light; an optical conductor including a light incident surface on which light emitted by the light source in allowed to be incident, a light output surface from which the light is allowed to be output, and a projection projecting from the light incident surface; and a light scattering section for scattering light, the light scattering section including an engaging portion which is engageable with the projection. The optical conductor and the light scattering section are located such that is an end of the projection of the optical conductors located outside the effective display area of the liquid crystal panel.
