Display device and an electronic apparatus using the same

摘要

In a conventional display device comprising a sub-display, the display device is increased in thickness and in the number of components as the number of displays is increased. In the present invention, a dual emission display device is used so that either surface of a display is used as a main display or a sub-display. Accordingly, the display device can be reduced in thickness and in the number of components. Further, mechanical reliability can be enhanced when the invention is applied to a tablet PC, a video camera and the like.

主权项

1. A display device comprising:
a light transmissive substrate which comprises a first surface and a second surface; a transistor over the first surface; a light emitting element over the first surface, the light emitting element comprising:
a first light transmissive electrode electrically connected to the transistor;a light emitting layer over the first light transmissive electrode; anda second light transmissive electrode over the light emitting layer, and a color filter over the first surface, wherein the first surface and the second surface are opposed to each other, wherein a first display surface is a side of the first surface, wherein a second display surface is a side of the second surface, wherein the light-emitting element emits a light, wherein the light passes through the second light transmissive electrode to the first display surface, wherein the light passes through the first light transmissive electrode to the second display surface, wherein the light is white light, wherein the first display surface is capable of emitting a different color light from the white light, and wherein the second display surface is capable of emitting the white light.
