Abstract
An object of the present invention is to form spacers for defining the space between the TFT substrate and the facing substrate of color filters, and by doing so, finely control the height of the spacers. First spacersare formed of green color filters G in pillar form on top of red color filters R and blue color filters B (green color filters G) having a large area between blue pixels BP; second spacersare formed by layering blue color filters B (green color filters G) and green color filters G having a large area on top of red color filters R in pillar form between green pixels GP; and the second spacersare shorter than the first spacersdue to the leveling effects of the layered blue color filters B (green color filters G) and green color filters G.
