Title:
ORGANIC LUMINESCENT ELEMENT
Document Type and Number:
Japanese Patent JP3832088
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an organic luminescent element excellent in monochromaticity.
SOLUTION: A hole and an electron are injected into an organic luminescent layer 94 from a transparent electrode 926 and a metal electrode 95 respectively in order to produce luminescence. Emitted light is confined in a photoconductive wave path formed by the transparent electrode 926 of a high refractive index sandwiched by an organic luminescent layer 94 of a low refractive index and a glass board 91, and is transmitted as conductive light wave in a direction in parallel with the glass board 91. A periodical distribution of the refractive index is formed in the photoconductive wave path by a dielectric formed periodically, and since diffracted light to light having a specific wave length corresponding to the period of the conductive wave light is transmitted in a reverse direction, an oscillator is formed, and only light determined by this oscillator is intensively emitted.
