PROBLEM TO BE SOLVED: To provide the display device which has good contrast in bright.dark conditions and is low in power consumption. SOLUTION: An organic EL light emitting element 12 is arranged at the back of a liquid crystal display section 13 as a back light and a reflection plate. Starting from the front side, the element 12 is formed by an anode electrode 19 consisting of ITO, an electroluminescence layer 18 made of an EL material and a reflection cathode electrode 15 made of MgIn having a reflectivity. Thus, external light beams are efficiently reflected by the electrode 15 and become the light beams for a display. Moreover, if the element 12 is driven, the emitted light beams are used for approximately 100% as display light beams. Thus, the display device having good contrast and low power consumption is obtained. |
