Abstract
A display device includes a transparent substrate, and a plurality of single-crystal thin-film semiconductor light-emitting elements disposed on one side of the transparent substrate. Each of the single-crystal thin-film semiconductor light-emitting elements is composed of single-crystal thin-film semiconductor layers separated from a base substrate, and includes a light-emitting layer and two non-light-emitting layers disposed on both sides of the light-emitting layer.
Claims17
A double-sided display device comprising:
- a transparent substrate having an upper surface and a lower surface opposite to each other;
- a first light-emitting element disposed above the upper surface of the transparent substrate and directly contacting the upper surface of the transparent substrate, the first light-emitting element being composed of single-crystal thin-film semiconductor layers including a first light-emitting layer and two non-light-emitting layers disposed on two opposite sides of the first light-emitting layer;
- a second light-emitting element disposed above the upper surface of the transparent substrate, the second light-emitting element being composed of single-crystal thin-film semiconductor layers including a second light-emitting layer and two non-light-emitting layers disposed on two opposite sides of the second light-emitting layer;
- a first non-light-transmission layer disposed above the first light-emitting element;
- and
- a second non-light-transmission layer disposed between the second light-emitting element and the upper surface of the transparent substrate.
