Method for manufacturing liquid crystal display device using a diffraction mask
View Patent ↗A method for manufacturing a liquid crystal display device is disclosed, in which a plurality of protrusions are formed on an organic insulating layer of a single layer, thereby obtaining a wide viewing angle. The method includes (a) forming an insulating layer on a substrate; (b) forming photoresist patterns having various shapes and heights on the insulating layer; (c) etching the insulating layer by using the photoresist patterns as masks so as to form protrusions on the surface of the insulating layer; and (d) forming a reflective layer on the insulating layer including the protrusions.
1. A method for manufacturing a liquid crystal display device comprising:
(a) forming an insulating layer on a substrate;
(a′) depositing a photoresist layer on the insulating layer, and
(b′) irradiating the photoresist layer with UV radiation through a diffraction mask to form the photoresist patterns having various shapes and heights on the insulating layer;
(c) etching the insulating layer by using the photoresist patterns as masks to form protrusions on a surface of the insulating layer; and
(d) forming a reflective layer on the insulating layer including the protrusions.
2. The method of claim 1 , wherein the insulating layer is an organic insulating layer.
3. The method of claim 2 , wherein the insulating layer is etched by a dry etching process.
4. The method of claim 1 , wherein the reflective layer is a metal layer.
