Abstract
A method of manufacturing a display screen provided with a filter pattern comprising a first pigment pattern and a second pigment pattern, which comprises the steps of, forming a first pigment layer by coating a solution containing a first pigment on a surface of a substrate and drying the resultant coated layer, forming a first pigment pattern by subjecting the first pigment layer to a patterned light exposure and developing the resultant exposed pattern, forming a second pigment layer by coating a solution containing a second pigment on the surface of the substrate including a surface of the first pigment pattern, and forming a second pigment pattern by selectively removing, through rinsing, a portion of the second pigment layer which is disposed on the first pigment pattern. At least either one of the solution containing a first pigment and the solution containing a second pigment contains an adhesion regulating agent so as to cause the adhesion strength between the first pigment pattern and the second pigment layer to become lower than the adhesion strength between the substrate and the second pigment layer, thus allowing a portion of the second pigment layer formed on the firs…
