Abstract:
An LCD(Liquid Crystal Display) and a fabrication method thereof are provided to form a black matrix and a spacer in a process by using a combined black matrix and old black spacer in a COT(Color Filter On Transistor) structure, thereby simplifying the process, reducing the necessary time, and improving yield. An LCD includes a first substrate, a second substrate, and an old black spacer(212). The second substrate is opposite to the first substrate. The old black spacer includes a black matrix formed between the first substrate and the second substrate. The old black spacer is formed in an inkjet type. A jet solution is black ink composed of a solvent and the old black spacer. The solvent of the black ink is a volatile substance.
Abstract:
PROBLEM TO BE SOLVED: To omit a complicated photolithography step for forming an overcoat layer in a method of manufacturing color filter substrate of an LCD device by forming the overcoat layer between a photothermal conversion layer and a color filter printing layer since thermal energy converted by the photothermal conversion layer when a color filter layer is formed is transmitted to the color filter printing layer through the overcoat layer to form first, second and third overcoat layers. SOLUTION: The method includes steps for: defining a plurality of pixel regions on a substrate and forming black matrix layers on the substrate except in the plurality of pixel regions; positioning a printing film including a color filter printing layer, the overcoat layer, and the photothermal conversion layer above the substrate; and patterning a corresponding color filter layer and a corresponding overcoat layer in each of the pixel regions by irradiating the printing film in a region corresponding to any one of the plurality of pixel regions with light.
