ABSTRACT:
A display device is provided which offers double-sided display and achieves a thin structure and also which prevents deterioration in display quality of each of front and back display units when an illumination unit such as a backlight is shared by these display units. The display device includes a first display unit having a display surface on the front surface thereof; a second display unit having a display surface on the rear surface thereof; and a common illumination unit interposed between the first display unit and the second display unit, for illuminating both the first display unit and the second display unit with light. A transflector is interposed between the second light-emitting surface of the light-guiding member and the second display unit.
