Abstract
A display apparatus includes a light guide plate, a first light source, a second light source, multiple first optical microstructures, multiple second optical microstructures, and a display panel. The first light source and the second light source are disposed beside a first light incident surface and a second light incident surface of the light guide plate respectively. Multiple second light beams emitted from the second light source irradiate a display surface of the display panel after being reflected by multiple second light receiving surfaces of the second optical microstructures disposed on a second light emitting surface of the light guide plate. Multiple first light beams emitted from the first light source exit the display apparatus after being reflected by multiple first light receiving surfaces of the first optical microstructures disposed on a first light emitting surface of the light guide plate.
