Patent ID: 7532299

Claim:
A method for fabrication of a substrate for a liquid crystal display device, comprising: forming a color filter layer on a substrate; coating an organic layer on the color filter layer, the organic layer having a single-layered structure; irradiating a first light substantially onto an entire area of the organic layer to pattern the organic layer; irradiating a second light onto the organic layer through a mask having a transmitting portion and a shielding portion, an energy density of the first light smaller than an energy density of the second light, wherein a portion of the organic layer is doubly exposed by the first and second lights; and forming an overcoat layer and a column spacer by developing the organic layer, wherein the column spacer corresponds to the portion doubly exposed, and the overcoat layer is formed by partially removing the other portion singly exposed by the first light in the developing of the organic layer.
