The invention provides a colour filter wherein a black matrix is formed on a transparent substrate and pixels com­ prising red auxiliary pixels, green auxiliary pixels, blue auxiliary pixels and auxiliary pixels of fourth a colour are formed at the aperture of this black mat­ rix or at the aperture of this black matrix and on this black matrix. The width (LI) of the black matrix between the aforementioned auxiliary pixels of the fourth colour and the other auxiliary pixels is 0 to 4.5 |im. The auxiliary pixels contain respective col­ orant and resin. The tristimulus value (Y) according to the CIE1931 colour system of the aforemen­ tioned auxiliary pixels of the fourth colour is 70 < Y < 99.
