Abstract:
1. A color filter comprising: a transparent substrate; a light shielding part, formed on the transparent substrate, containing at least a light shielding material and a resin; and a pixel part formed at an opening of the light shielding part on the transparent substrate, wherein when an edge side shape, in a range of 100 μm to 200 μm in length, of the light shielding part is converted into coordinate data having coordinate points in a range of 1000 points to 10000 points, and an approximate line is calculated from the coordinate points by least-square method, and a standard deviation of: wherein n is a number of the coordinate points in the coordinate data, wherein X in a graph of the coordinate data, when an apex of a peak projecting upward is referred to as an upper apex and an apex of an peak projecting downward is referred to as a lower apex, among peaks whose distance from the approximate line is 1.0 μm or more, a distant between the adjacent upper apexes and a distant between the adjacent lower apexes are 5.0 μm or more on average.
