Display device

A display device comprising:

• a light guide plate including first and second transparent plates, each of the first and second transparent plates including first and second opposed end faces, a light transmission portion at the first end face, an antireflection portion at the second end face, and a light extraction surface transverse to the first and second end faces, the first and second transparent plates being placed one over the other so that the light extraction surfaces are oriented in the same direction and so that the light transmission portions at the first end faces are at opposite sides of the light guide plate;
• first and second light sources respectively located opposite the light transmission portions at the first end faces of the first and second transparent plates;
• a transmission liquid crystal panel located adjacent to the light extraction surface of one of the first and second transparent plates;
• and
• a synchronous drive unit that alternately turns on and off the first and second light sources so that an image is displayed on the liquid crystal display panel and is synchronous with alternating turn turning on and turning off of the transmission liquid crystal panel.
