Light-emitting device and exposure device and flat display device using the same
First Claim
1. A light-emitting device comprising:
- a display light-emitting part made of a laminate of a first electrode, an organic EL layer, a photoconductive layer and a second electrode in sequence; and
an external light-emitting part laminated on said second electrode side of said display light-emitting part, said photoconductive layer of said display light-emitting part receiving light emitted from said external light-emitting part, said photoconductive layer being made of a photoconductor having a current amplification mechanism so that carriers generated in a photoelectric conversion process are multiplied by said current amplification mechanism.

Abstract
A light-emitting device comprising a display light-emitting part 43 made of a laminate of a first electrode 47, an organic EL layer 49, a photoconductive layer 51 and a second electrode 53 in sequence; and an external light-emitting part 45 laminated on the second electrode 53 side of the display light-emitting part 43, the photoconductive layer 51 receiving light emitted from the external light-emitting part 45, the photoconductive layer 51 being made of a photoconductor having a current amplification mechanism for multiplying carriers generated in a photoelectric conversion process. For example, a photoconductor having a current amplification mechanism using an avalanche effect can be preferably adapted to the photoconductive layer 51.
