Abstract
Provided is a display device that can be realized with a simple configuration and functions as a transparent display allowing background to be clearly seen therethrough. When a liquid crystal panel is in an ON state, polarized backlight that is incident from a polarized backlight unit reaches a front surface. At this point, ambient light that is incident from a rear side also reaches the front surface. Accordingly, an observer who is on a front side of a transparent display can visually recognize an image that is displayed in an overlaid manner on the background seen through the transparent display. In a case where the liquid crystal panel is placed into an OFF state, the polarized backlight cannot reach the front surface of the transparent display, and the ambient light reaches the front surface.
