Abstract

The present disclosure provides a method of manufacturing a display device. The method includes: providing a substrate; forming an electroluminescence element on the substrate; forming a partition structure on the electroluminescence element, the partition structure including an opening; forming a light conversion element in the opening; and forming an optical element on the light conversion element.

Claims (21)

1. A method of manufacturing a display device, comprising:

providing a substrate;

forming an electroluminescence element on the substrate;

forming a partition structure on the electroluminescence element, the partition structure comprising an opening;

forming a light conversion element in the opening;

forming an intermediate layer on the light conversion element; and

forming an optical element on the light conversion element,

wherein the intermediate layer is disposed between the light conversion element and the optical element, the intermediate layer has a protrusion and a recess, the protrusion overlaps the light conversion element in a top-view direction, the recess overlaps the partition structure in the top-view direction, and a thickness of the protrusion is greater than a thickness of the recess.

2. The method of claim 1 , wherein the optical element is formed by ink-jet printing.

3. The method of claim 1 , wherein the optical element is formed by screen printing.

4. The method of claim 1 , wherein the optical element is formed by photolithography.

5. The method of claim 1 , wherein the optical element is formed by a transferring process.

6. A method of manufacturing a display device, comprising:

providing a substrate;

forming an electroluminescence element on the substrate;

forming a partition structure on the electroluminescence element, the partition structure comprising an opening;

forming a light conversion element in the opening;

forming an intermediate layer on the light conversion element; and

forming an optical element on the light conversion element,

wherein the intermediate layer is disposed between the light conversion element and the optical element, and the intermediate layer has a first part and a second part;

wherein in a top-view direction, the first part overlaps the light conversion element, the second part overlaps the partition structure, and a thickness of the first part is greater than a thickness of the second part.
