A color filter substrate comprising: a transparent substrate having an effective display region and a frame region enclosing the effective display region; a first color filter (GF, RF), a second color filter (RF, GF) and a third color filter formed of linear patterns on the transparent substrate such that individual colors are different from each other and adjacent to each other with no gap therebetween; and a second light-shielding layer formed on the first color filter, the second color filter and the third color filter, the second light-shielding layer having visible range light-shielding effect, wherein: the first color filter (GF, RF) is arranged so as to divide the second color filter (RF, GF) from the third color filter; the first color filter (GF, RF) has a line width which is substantially 1/2 of that of the second color filter (RF, GF) and the third color filter; and the first color filter (GF, RF), the second color filter (RF, GF) and the third color filter have no formation of a convex portion which is attributed to an overlap of at least two of the color filters of the different colors, characterized in that the second light-shielding layer contains organic pigments as a main material of light-shielding color materials and has infrared transmission; wherein, in the frame region, a first light shielding layer is provided on the transparent substrate and the second light shielding layer is provided on the first light shielding layer, the first light shielding layer has visible range light-shielding effect and does not have infrared transmission, alignment marks are provided in the first light shielding layer provided in the frame region. a transparent substrate having an effective display region and a frame region enclosing the effective display region; a first color filter (GF, RF), a second color filter (RF, GF) and a third color filter formed of linear patterns on the transparent substrate such that individual colors are different from each other and adjacent to each other with no gap therebetween; and a second light-shielding layer formed on the first color filter, the second color filter and the third color filter, the second light-shielding layer having visible range light-shielding effect, wherein: the first color filter (GF, RF) is arranged so as to divide the second color filter (RF, GF) from the third color filter; the first color filter (GF, RF) has a line width which is substantially 1/2 of that of the second color filter (RF, GF) and the third color filter; and the first color filter (GF, RF), the second color filter (RF, GF) and the third color filter have no formation of a convex portion which is attributed to an overlap of at least two of the color filters of the different colors, the first color filter (GF, RF) is arranged so as to divide the second color filter (RF, GF) from the third color filter; the first color filter (GF, RF) has a line width which is substantially 1/2 of that of the second color filter (RF, GF) and the third color filter; and the first color filter (GF, RF), the second color filter (RF, GF) and the third color filter have no formation of a convex portion which is attributed to an overlap of at least two of the color filters of the different colors, characterized in that the second light-shielding layer contains organic pigments as a main material of light-shielding color materials and has infrared transmission; wherein, in the frame region, a first light shielding layer is provided on the transparent substrate and the second light shielding layer is provided on the first light shielding layer, the first light shielding layer has visible range light-shielding effect and does not have infrared transmission, alignment marks are provided in the first light shielding layer provided in the frame region.
