Color filter substrate, liquid crystal display device, and method for manufacturing color filter substrate

A color filter substrate, comprising:

• a transparent substrate having an effective display region and a frame region enclosing the effective display region;
• a plurality of color filters including a first color filter, a second color filter and a third color filter having different colors, the color filters being formed in linear patterns on the transparent substrate such that adjacent two of the first, second, and third color filters are formed without a gap therebetween;
• a light-shielding layer formed on the first color filter, the second color filter and the third color filter, the light-shielding layer including an organic pigment as a main material of a light-shielding color material and being capable of shielding a visible light and transmitting an infrared light;
• a second light-shielding layer formed including carbon as the main material of the light-shielding color material;
• and
• a third light-shielding layer formed including the organic pigment as the main material of the light-shielding color material,
• wherein the second light-shielding layer including carbon and the third light shielding color layer including the organic pigment are formed in the frame region,
• wherein the first color filter is positioned such that the second color filter is separated from the third color filter,
• the first color filter has a line width which is substantially ½ of a line width of the second color filter and a line width of the third color filter, and
• the first color filter, the second color filter and the third color filter have no projection formed by an overlap of at least two color filters of different colors.
