ABSTRACT:
A color filter being precisely and easily manufactured while solving an alignment problem is provided. Further, a method for manufacturing a color filter structure formed in a display panel that has front and rear substrates opposed to each other is provided. This method is provided with: a first step of forming a composite layer (11, 12, 1G,1C,1S,1D) that includes a pixel drive element in a rear substrate10; a second step of patterning a first rib42along a boundary of a pixel region on or above the composite layer and a second rib44arranged in the pixel area, the second rib having a height that is smaller than that of the first rib42in accordance with a photolithography technique; a third step of dropping a light transmission material in a reflection region Pr defined by the first rib42and the second rib44and forming a stepped layer7in accordance with an ink jet technique; and a fourth step of, after the stepped layer7has been formed, dropping a light coloring material9in a region defined by the first rib42and forming a color layer in accordance with an ink jet technique.
