Abstract:
1. A display device comprising: a substrate which transmits light; a first display surface above a top surface of the substrate; a second display surface below a bottom surface of the substrate; a counter substrate opposite to the substrate; two polarizers of different polarizations sandwiching the substrate and the counter substrate and between the first display surface and the second display surface; and a transistor and a light-emitting element between the top surface of the substrate and the first display surface, the transistor being electrically connected to the light-emitting element, wherein the light-emitting element emits light to the first display surface and to the second display surface, wherein light emitted by the light-emitting element reaches the first display surface and the second display surface by passing through one polarizer only, wherein light obtained from the light-emitting element is white, and wherein each of the first display surface and the second display surface performs monochrome display.
