ABSTRACT:
A backlight assembly may include a light guide unit, a light source and a reflection module. The light source provides light onto an incident face of the light guide unit. The reflection module may include a first substrate having reflection regions, a lower electrode disposed in each reflection region, a switch element applying an on or off signal to the lower electrode, and an upper electrode. The upper electrode makes contact with or is spaced apart from a reflective face of the light guide unit in accordance with the on or off signal. Thus, light selectively exits the light guide unit through an exiting face of the light guide unit corresponding to each reflection region. A display device has a display module disposed on the exiting face of the light guide unit to display an image. Therefore, the display device has a simplified structure.
