Claim:
1. A method of manufacturing a thin film transistor substrate, comprising: forming a signal line section on a base substrate to define a plurality of pixel areas; etching the base substrate using the signal line section as a mask to form a plurality of trenches in the base substrate, the plurality of trenches corresponding to the pixel areas, respectively; disposing a color filter material in each trench by using an inkjet printing method to form a color filter layer; forming an organic layer on the color filter layer and the signal line section; forming a thin film transistor on the organic layer; and forming a pixel electrode electrically connected to the thin film transistor, wherein a first distance from a lower surface of the base substrate to an upper surface of the color filter layer is identical to a second distance from the lower surface of the base substrate to a lower surface of the signal line section.
