Patent ID: 8411233

Claim:
A method for manufacturing a color filter substrate for use in combination with a thin-film-transistor substrate that includes an array of pixels and associated thin film transistors disposed in a vicinity of intersections of gate lines and signal lines, said pixels each including an effective opening area and a shielded area encircling said effective opening area, said method comprising in a sequential order: forming a plurality of first color filter layers with a spacing formed in an extending direction of said gate lines between each of the plurality of first color filter layers, the color filter layers including a first stripe portion extending in a direction parallel to said signal lines, and a pair of extension portions extending from said first stripe portion in opposite directions parallel to said gate lines; forming a plurality of second color filter layers including a second stripe portion extending in a direction parallel to said signal lines, and a pair of second extension portions extending from said second stripe portion in opposite directions parallel to said gate lines adjacent to each said first color filter layer so that said second stripe portion is in parallel to said first stripe portion, and said second stripe portion and said first stripe portion are partially stacked on each other; and forming a plurality of third color filter layers including a third stripe portion extending in a direction parallel to said signal lines, and a pair of third extension portions extending from said stripe portion in opposite directions parallel to said gate lines adjacent said first color filter layer and said second color filter layer so that said third stripe portion is in parallel to said first and second stripe portions, and said third stripe portion is partially stacked on said first and second stripe portions, wherein said first through third color filter layers have different colors, a first color-stacked light shield section including color filter layers with two different colors stacked on each other in a portion of an area corresponding to said light shielded area on said color filter substrate is formed due to said first through third stripe portions adjacent to each other that are stacked on each other, and a second color-stacked light shield section including color filter layers with three different colors stacked on each other in a portion of an area corresponding to said light shielded area on said color filter substrate is formed due to said first through third color filter layers that are formed such that said pair of first through third extension portions are extended on a line parallel to an extending direction of said gate lines.
