Abstract
A light guide plate including a light emitting surface, a bottom surface, a light incident surface, multiple protrusion structures, and multiple grooves is provided. The light incident surface is connected between the light emitting surface and the bottom surface. The protrusion structures are disposed along a first direction and extend toward a second direction. The protrusion structures have a light condensing angle along the first direction, and the light condensing angle ranges from 10 degrees to 40 degrees. The grooves are disposed in the protrusion structures of the light guide plate. The grooves extend toward the first direction. The protrusion structures have a light receiving surface that defines each groove and is closer to the light incident surface. An angle between the light receiving surface and the bottom surface ranges from 35 degrees to 65 degrees. A display apparatus adopting the light guide plate is also provided.
