Abstract
A display device includes a base substrate and a partition wall structure disposed on the base substrate, the partition wall structure including light control particles, and having an accommodation opening, and a color conversion layer disposed within the accommodation opening, and including color conversion particles, where a density of the light control particles located at an outer portion of the partition wall structure is greater than a density of the light control particles located at a center portion of the partition wall structure.
Claims20
A display device comprising:
- a base substrate;
- a partition wall structure disposed on the base substrate, wherein the partition wall structure includes an accommodation opening and light control particles;
- and
- a color conversion layer disposed within the accommodation opening, and including color conversion particles,
- wherein a density of the light control particles disposed at an outer portion of the partition wall structure is greater than a density of the light control particles disposed at a center portion of the partition wall structure.
A method of manufacturing a display device, the method comprising:
- forming a preliminary partition wall layer on a base substrate to cover the base substrate;
- disposing a mask having an opening on the preliminary partition wall layer;
- exposing the preliminary partition wall layer exposed by the opening;
- developing the preliminary partition wall layer with a developer containing light control particles to leave a first portion of the preliminary partition wall layer and to remove a second portion of the preliminary partition wall layer;
- curing the first portion of the preliminary partition wall layer to form a partition wall structure having an accommodation opening;
- and
- forming a color conversion layer having color conversion particles in the accommodation opening.
