LIGHT-EMITTING DEVICE

摘要

Disclosed is a light-emitting device (1) comprising a light-emitting layer (2) containing a phosphor and at least two electrodes (6, 7). The light-emitting device (1) also comprises at least two electrically insulating layers (2, 9) having different dielectric constants, and one of the electrically insulating layers (2, 9) is the light-emitting layer (2). Either one of the electrodes (6, 7) is formed in contact with one of the insulating layers. Consequently, a light-emitting device which is capable of emitting a light by utilizing surface discharge can be produced at low cost. The light-emitting device has a good luminous efficiency, and the power consumption can be low when a large-screen display is produced using this light-emitting device.
