Abstract
An electroluminescence display device including a substrate, a corrugated structure formed on the substrate, wherein the corrugated structure disperses light through diffraction and reflection; and a first electrode layer, a first insulation layer, a fluorescent layer, a second insulation layer, and a second electrode layer sequentially formed on the substrate to follow the shape of the corrugated structure.
Claims23
An electroluminescence display device comprising:
- a substrate;
- a corrugated structure formed on the substrate, wherein the corrugated structure disperses light through diffraction and reflection;
- and
- a first electrode layer, a first insulation layer, a fluorescent layer, a second insulation layer, and a second electrode layer sequentially formed on the substrate to follow the shape of the corrugated structure.
An electroluminescence display device comprising:
- a transparent substrate;
- a corrugated structure dispersing light through diffraction and reflection;
- and
- a first electrode layer, a first insulation layer, a fluorescent layer, a second insulation layer, and a second electrode layer sequentially formed on the substrate,
- wherein the corrugated structure is formed on the substrate or on at least one of the sequentially formed layers, and at least one of the sequentially formed layers is formed on the corrugated structure to follow a shape of the corrugated structure.
A method of manufacturing an electroluminescence display device, the method comprising:
- preparing a transparent substrate;
- forming an insulation thin-film layer on the transparent substrate;
- forming a photoresist layer on the insulation thin-film layer;
- patterning the photoresist layer using a laser hologram;
- etching the patterned photoresist layer;
- and
- etching the insulation thin-film layer using the etched photoresist layer, thereby forming a corrugated structure which disperses light through diffraction and reflection.
