Display device and electronic apparatus

Abstract

According to one feature of the invention, a display device comprises a pixel including a first sub-pixel having a first light-emitting element and a second sub-pixel having a second light-emitting element, a first source driver connected to a first source line included in the first sub-pixel, and a second source driver connected to a second source line included in the second sub-pixel. The first sub-pixel and the second sub-pixel are provided over one surface of a light-transmitting substrate, and a first display region using the first sub-pixel over one surface of the substrate and a second display region using the second sub-pixel over the opposite surface the substrate are provided. Accordingly, it is possible to provide a display device that realizes sophistication and a high added value, which includes a display region in each of one and the opposite sides.
