摘要：
Disclosed is a method of producing color filters, which comprises forming a layer of an organic polymeric material having a predetermined light-sensitive characteristic on a substrate (21) exposing this layer to a predetermined pattern, developing the exposed layer to form a filter base (24) and dyeing the filter base (24), wherein after the development of the exposed layer, the layer is wetted with a dehydrating agent (25) to remove water from the filter base (24). By this dehydrating treatment, the filter base (24) can be produced without distortion to a very high precision. The dehydrating agent (25) can be an anhydrous or water-diluted alcohol, such as methanol.
