Abstract

PURPOSE:To keep the constant color output level, by providing the light shield layer on or under the filter element every color filter element and adjusting the output level with the light shield layer. CONSTITUTION:In forming the color separation filter, the color separation filter layer 12 is provided on the transparent substrate 11 in the order or R, G and B, and it is located at the boundary of the filter layer 12 on the substrate 11 to form the light shield layer 13 increasing the effective area in the order of B, G and R.
