Abstract
The present invention discloses a full-color organic electroluminescent device using an organic electroluminescent element capable of emitting of ultra-violet light with wave length 380.about.400 nm as a basic element, coated with a layer of different fluorescent media (wave length converting layer) on its surface. By way of this ultra-violet light organic electroluminescent element, ultra-violet light is produced, which in turn excites the fluorescent layer to emit fluorescent lights with different colors according to the fluorescent media used, i.e. the red fluorescent medium emits red light, and the green fluorescent medium emits green light. R, G, B three color fluorescent media emit white light. By applying this principle, a high brilliance, low current and low energy consuming full-color display device may be fabricated.
