ABSTRACT:
A method for producing a color filter substrate is provided. The color filter substrate includes a base plate having a first side and a second side opposed to the first side, and a color filter layer provided on the base plate and including at least a first color layer having a plurality of first color portions and a second color layer having a plurality of second color portions. The at least the first color layer and the second color layer including a final color layer. The plurality of first color portions and the plurality of second color portions are respectively adjacent to each other. The method includes the step of forming a color filter layer. The step of forming the color filter layer includes a repetition of the steps of applying a dry film on the base plate from the first side to the second side of the base plate while pressing the dry film by a laminate method; and patterning the dry film applied on the base plate, thereby forming a color layer including a plurality of color portions. The final color layer is formed on at least a part of exposed surface areas extending from the first side to the second side. The dry film for forming the final color layer is applied while expelling from between the dry film and the base plate through the exposed surface areas.
