Abstract
A first layer of first dye receiving resin is deposited to a even thickness on a substrate or on an imaging area of a solid-state imager. A first color region is patterned on the surface of the first layer and dyed in a first color. A second layer is patterned on the first layer and the dyeing property of the second layer differs from that of the first dye receiving layer. A second color region, overlapping with the first color region over at least one pixel, is formed by the second layer, or the first and second color regions are formed in the first layer and a third color region is formed by the second layer between the first and second color regions in the first layer. The first dye receiving resin is hydrophobic and the second is hydrophilic when the filter is formed on the surface of a solid-state imager, and vice versa when the filter is formed on a substrate. A light intercepting layer intervenes between the first and second layers.
