Abstract
A color filter, particularly a color filter for a solid state imaging device, comprising a dyeable resin layer, a plurality of variously colored dyed-areas formed in the dyeable resin layer, a plurality of non-dyed areas separating the dyed area from each other in the dyeable resin layer, and a plurality of photo-interception areas formed on the non-dyed areas is disclosed. The dyed areas are generally separated from each other by a distance greater than the diffusion length generated during dyeing or heat treatment. The dyed areas can also be spread under the photo-interception areas by a distance substantially equal to the diffusion length generated during dyeing or heat treatment.
