Abstract
A process for producing color filters which enable a transparent electrode for forming a coloring matter film to be used as a transparent electrode for driving liquid crystals, and a resist for a light-shielding film used in this process for forming an insulating black matrix, is disclosed. The above production method comprises forming a black matrix over electrodes other than those corresponding to the individual separated colors and, at the same time, insulating layers as electrode contact window belts by utilizing the black matrix material; forming the electrode contact window belts by forming an electrically conductive layer over the black matrix so that they connect within each electrode contact window belt unit, but do not connect with those in different electrode contact window belt units; and forming a coloring matter layer by a micellar disruption method.
