Abstract (en)
A light-emitting element (1) includes a light-emitting layer (2) including a phosphor, and at least two electrodes (6, 7). The light-emitting element (1) includes at least two kinds of electrically insulating layers (2, 9) with different dielectric constants. One of the electrically insulating layers (2, 9) is the light-emitting layer (2), and one of the two electrodes (6, 7) is formed in contact with one of the insulating layers. Therefore, it is possible to provide a light-emitting element that can emit light by using surface discharge, is manufactured at low cost, exhibits favorable luminous efficiency, and is to be driven with low power consumption when being applied to a large-screen display.
