Abstract: An optical waveguide plate has a front surface and a back surface, and includes an in-coupling element and an out-coupling element. The in-coupling element and the out-coupling element are disposed on at least one of the front surface and the back surface. An in-coupling area is an area of the at least one of the front surface and the back surface on which the in-coupling element is disposed, and an out-coupling area is an area of the at least one of the front surface and the back surface on which the out-coupling element is disposed. A thickness of the optical waveguide plate is gradually increased from the in-coupling area towards the out-coupling area.
