Abstract

A liquid crystal display including a liquid crystal panel and an organic EL device, which functions as a backlight. The organic EL device includes a Peltier element, which functions as a substrate, and an organic EL element formed on the Peltier element. The organic EL element includes an organic EL layer and first and second electrodes, which sandwich the organic EL layer. The first electrode is shared with a metal layer, which is a heat absorbing electrode of the Peltier element. The second electrode is formed from ITO, which transmits visible light. Light emitted from the organic EL element exits from the second electrode. As a result, the organic EL device is thin and has a superior cooling effect.
