Abstract
Color reproduction is improved by reducing color noise without changing color signal processing of a device in such a manner to match a new color filter arrangement. The film thickness of a green (G) color layer in a Bayer color arrangement is made thin to be the green (G) color layer having a steeply inclined spectral characteristic with a high range of transmissivity extended towards the short wavelength, and a yellow (Y1) color layer with a thin film thickness is newly stacked on the thinned green (G1) color layer. Thereby the y-axis value of the spectral characteristic of green (G) of the green (G) color layer becomes greater than or equal to 0.45 and less than or equal to 0.60 on a CIE chromaticity diagram.

Color filters of the three primary colors comprising a red (R) color layer, a green (G) color layer, and a blue (B) color layer in a predetermined color arrangement in a plane view, wherein a spectral characteristic of green (G) of the green (G) color layer has a y-axis value greater than or equal to 0.45 and less than or equal to 0.60 on a CIE chromaticity diagram.
