LIGHT EMITTING ELEMENT AND PRODUCTION METHOD THEREFOR AND DISPLAY DEVICE

Title:

LIGHT EMITTING ELEMENT AND PRODUCTION METHOD THEREFOR AND DISPLAY DEVICE

Document Type and Number:

WIPO Patent Application WO/2004/016049

Kind Code:

A1

Abstract:

A light emitting element comprising a porous luminous body including an insulation element having voids and inorganic fluorescent substance particles, and at least two electrode provided so as to contact the surface of the luminous body, wherein voltage is applied to the at least two electrodes to generate discharge that excites the luminous body to emit light. Accordingly, the light emitting element least suffers the brightness deterioration and reliability lowering of the fluorescent substance, and requires no vacuum sealing and high-voltage application, unlike in the case of glow discharge, and an advanced thin film technology. When such light emitting elements are two-dimensionally arranged in a matrix form, a simple-structure and low-cost flat display device can be provided.
