Light condensing light guide plate and display apparatus

A light guide plate including a light emitting surface, a bottom surface, a light incident surface, a plurality of protruding structures and a plurality of grooves is provided. The light emitting surface is opposite to the bottom surface. The light incident surface is connected between the light emitting surface and the bottom surface. The protruding structures are disposed on the bottom surface. The protruding structures are arranged along a first direction and extend toward a second direction. The first direction is perpendicular to the second direction. The second direction is perpendicular to the light incident surface. The grooves are disposed in the protruding structures of the light guide plate. The grooves are arranged along the second direction and extend toward the first direction. The protruding structures have a light receiving surface that defines each groove and is closer to the light incident surface. An angle included between the light receiving surface and the bottom surface is between 35 deg
