Color filter and method for manufacturing the same

The method for manufacturing a color filter, comprising the steps of:

• preparing a substrate produced by forming an organic semiconductor film or an inorganic semiconductor film on a transparent electroconductive film formed on a transparent substrate;
• preparing a water-based liquid in a vessel that can hold a liquid, the water-based liquid containing a coloring material and an electrodeposition material that is chemically dissolved or precipitated/sedimented based on changes in the pH;
• disposing, in said vessel, an apparatus having a counter electrode which is the other of a pair of electrodes and securing said substrate, in which means for providing a current or an electric field according to at least an image pattern is connected to said transparent electroconductive film, such that a semiconductor thin film is dipped in said water-based liquid;
• and
• applying light on the transparent substrate of said substrate to selectively precipitate an electrodeposition film which contains the electrodeposition material on a portion at which electromotive force was generated with light irradiation, thereby forming a monochromatic color filter.

• and
• applying light on the transparent substrate of said substrate while optionally applying bias voltage to said transparent electrodeposition film to selectively precipitate an electrodeposition film which contains the electrodeposition material on a portion at which electromotive force was generated with light irradiation, thereby forming a monochromatic color filter.

The method for manufacturing a color filter, comprising the steps of:

• preparing a substrate having an organic or an inorganic semiconductor film on a transparent electrode formed on a transparent substrate;
• preparing a water-based liquid containing a coloring material and an electrodeposition material that is dissolved or precipitated based on variations of pH values of the water-based liquid;
• disposing a counter electrode with the semiconductor film in the water-based liquid and providing an electric current or electric field therebetween;
• and
• exposing the substrate to light to generate a photo electromotive force to change the pH value of the water-based liquid adjacent to the semiconductor film, thereby precipitating the electrodeposition material.
