Abstract:
An illumination apparatus includes a light guide plate having a plurality of first and second diffusion net points formed on a surface of a light transmissive substrate, and at least one light emitting element disposed to emit light into a light incident surface of the light guide plate. A portion of the first diffusion net points at least partially overlaps the second diffusion net points, and the size of the first diffusion net points is smaller than the size of the second diffusion net points.
