Abstract
Disclosed is a method for fabricating a color filter for a transflective liquid crystal display device inexpensively in which desired color purities, brightnesses, and color tones are obtained for reflective display and transmissive display. A color filter for a liquid crystal display device includes pixels of a plurality of colors, each pixel of at least one color including a transmissive area and a reflective area. The pixel of at least one color includes a plurality of laminated color layers. The uppermost color layer in the pixel including the plurality of laminated color layers is composed of a photosensitive color resist. In the reflective area of the pixel including the plurality of laminated color layers, a transparent resin layer is disposed between a substrate and the color layer portion.
