Abstract
A method of patterning a color conversion layer for an organic EL device is provided together with a method of manufacturing a multiple color emitting organic EL display using the patterning method. The patterning method includes forming the color conversion layer on a base having an organic layer and patterning the color conversion layer by carrying out a thermal cycle nano imprint technique.
Claims22
A method of patterning a color conversion layer comprising:
- forming the color conversion layer on top of a base;
- and
- patterning the color conversion layer by carrying out a thermal cycle nano imprint technique.
A method of manufacturing an organic EL display comprising:
- providing at least two kinds of color filter layers, each transmitting light in a different wavelength region, on a base;
- forming a planarization layer over the color filter layers;
- forming a color conversion layer over the planarization layer, wherein the color conversion layer absorbs light of a first wavelength and emits light including a second wavelength that differs from the first wavelength;
- and
- patterning the color conversion layer by carrying out a thermal cycle nano imprint technique forming a barrier layer over the patterned color conversion layer.

A method of manufacturing an organic EL display comprising:
- providing a color filter structure by providing at least two kinds of color filter layers, each transmitting light in a different wavelength region, on a base, forming a planarization layer over the color filter layers, and forming a first barrier layer over the planarization layer;
- providing an organic EL device by forming an organic EL layer on a device substrate, forming a color conversion layer over the organic EL layer, wherein the color conversion layer absorbs light of a first wavelength and emits light including a second wavelength that differs from the first wavelength, patterning the color conversion layer by carrying out a thermal cycle nano imprint technique, and forming a second barrier layer over the color conversion layer;
- and
- bonding the color filter structure to the organic EL device so that the first barrier layer and the second barrier layer are opposite to each other.
