SURFACE LIGHT-EMITTING DEVICE AND ILLUMINATING APPARATUS AND DISPLAY APPARATUS INCLUDING THE SAME

摘要

There is provided a surface light-emitting device that improves the light emission efficiency and an illuminating apparatus and a display apparatus that include the surface light-emitting element. A surface light-emitting device includes transparent substrate 1 including a central thick portion 1b protruding in the direction of light emission and a periphery thin portion 1a to be held by a holder; transparent electrode 2 laminated on transparent substrate 1 and functioning as an anode; metal electrode 6 opposite transparent electrode 2 and functioning as a cathode; and light-emitting layer 4 sandwiched between transparent electrode 2 and metal electrode 6.
