Abstract
Disclosed herein is a process for producing a color filter, which comprises the steps of forming a resin layer on a substrate, pre-curing the resin layer, exposing the resin layer, developing the resin layer to form black matrices between which space areas are defined, heating the black matrices under reduced pressure and separately applying inks to the space areas.
