Abstract
A liquid crystal display according to an exemplary embodiment of the inventive concept includes a substrate; a thin film transistor positioned on the substrate; a pixel electrode connected to the thin film transistor; a roof layer positioned to face the pixel electrode; a liquid crystal layer positioned between the pixel electrode and the roof layer within a plurality of microcavities; a capping layer positioned adjacent to the microcavities; and a color conversion panel including a plurality of color conversion media layers on the roof layer and the capping layer, wherein the capping layer is positioned along a trench formed between the plurality of microcavities.
Claims19
A liquid crystal display, comprising:
- a substrate;
- a thin film transistor positioned on the substrate;
- a pixel electrode connected to the thin film transistor;
- a roof layer overlapping the pixel electrode;
- a liquid crystal layer positioned between the pixel electrode and the roof layer within a plurality of microcavities;
- a capping layer positioned adjacent to the microcavities;
- and
- a color conversion panel including a plurality of color conversion media layers on the roof layer and the capping layer, wherein the capping layer is positioned along a trench formed between the microcavities and includes a photosensitive material.
A method of manufacturing a liquid crystal display, the method comprising:
- forming a thin film transistor on a substrate;
- forming a pixel electrode on the thin film transistor;
- forming a sacrificial layer on the pixel electrode;
- forming a roof layer on the sacrificial layer;
