Abstract
A display apparatus including a display and a waveguide plate is provided. The display panel includes multiple rows of display units and multiple rows of solar cell units. The display units and the solar cell units are substantially parallel to a first direction and alternately arranged along a second direction perpendicular to the first direction. The waveguide plate is disposed at one side of the display panel. A first side of the waveguide plate adjacent to the display panel includes multiple microstructures. First and second structure surfaces of each microstructure respectively correspond to one row of the display units and one row of the solar cell units. When the display apparatus is disposed such that the second direction is perpendicular to a ground surface, an inclination of the first structure surface makes a thickness of the waveguide plate gradually decrease along an upward direction from the ground surface.
