Method of fabricating a liquid crystal display device having column spacers and overcoat layer formed by double exposure
摘要：
A method for fabrication a substrate for a liquid crystal display device includes: forming a color filter layer on a substrate; coating an organic layer on the color filter layer; irradiating a first light onto 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; and forming an overcoat layer and a column spacer by developing the organic layer.
