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 substrate 10; a second step of patterning a first rib 42 along a boundary of a pixel region on or above the composite layer and a second rib 44 arranged in the pixel area, the second rib having a height that is smaller than that of the first rib 42 in accordance with a photolithography technique; a third step of dropping a light transmission material in a reflection region Pr defined by the first rib 42 and the second rib 44 and forming a stepped layer 7 in accordance with an ink jet technique; and a fourth step of, after the stepped layer 7 has been formed, dropping a light coloring material 9 in a region defined by the first rib 42 and forming a color layer in accordance with an ink jet technique.
