Abstract
The purpose is to suppress a temperature rise in the LED and the driver IC for a reliable transparent liquid crystal display device. An example of concrete structure to attain the purpose is: A display area is formed in an area where the TFT substrate and the counter substrate overlap, a terminal area is formed in an area where the TFT substrate and the counter substrate do not overlap, an LED is disposed in the terminal area opposing to a side surface of the counter substrate, the LED is connected to a printed wiring substrate, a driver IC to drive the liquid crystal display device is disposed in the terminal area, a metal plate is disposed between the driver IC and the printed wiring substrate, the metal plate contacts the printed wiring substrate via a first heat dissipation sheet, and contacts the driver IC via a second heat dissipation sheet.
