US 2021/0263345 A1 · DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME

Abstract

A display device including a first substrate, a pixel disposed on the first substrate and including first, second and third sub-pixel electrodes adjacent to each other, a second substrate spaced from the first substrate, a color conversion layer disposed on the second substrate and with a first wavelength conversion layer overlapping with the first sub pixel electrode and a second wavelength conversion layer overlapping with the second sub pixel electrode, a transmissive layer including a first sub-transmissive layer overlapping with the third sub-pixel electrode and a second sub-transmissive layer disposed between the first wavelength conversion layer and the second wavelength conversion layer, and a planarization layer disposed on the color conversion layer and the transmissive layer. A method of manufacturing a display device having a flatter planarization layer with reduced variations in thickness is also disclosed.

Dependent claims

A display device comprising:

a substrate;
a color conversion layer disposed on the substrate and comprising a first wavelength conversion layer configured to receive a light of a first wavelength range and to convert the light of the first wavelength range into a light of a second wavelength range, and a second wavelength conversion layer configured to receive the light of the first wavelength range and to convert the light of the first wavelength range into a light of a third wavelength range;
a filter disposed on the color conversion layer and configured to transmit the light of the first wavelength range and to reflect the light of the second wavelength range and the light of the third wavelength range;
a transmissive layer disposed on the filter and configured to transmit the light of the first wavelength range;
and
a planarization layer disposed on the transmissive layer.
