색소막 형성용의 투명전극을 액정 구동용의 투명전극에 사용할 수 있는 컬러필터의 제조방법 및 이 방법에 있어서 절연성의 블랙 매트릭스를 형성하는 데에 사용되는 차광막용 레지스트가 개시되어 있다. 상기 제조방법은, 색분해된 개별의 색에 상당하는 투명전극 이외의 전극상에 블랙 매트릭스의 형성과 동시에 블랙 매트릭스재로 전극인출 창구대로서의 절연층을 형성하고, 이어서 그 위에서 부터 각각의 전극인출 창구대 단위내는 전기적으로 접속되고, 또한 다른 전극인출 창구대와는 전기적으로 접속되지 않도록 도전층을 형성하므로서 전극인출 창구대의 각각을 형성한 후, 상기 색소층을 미셸 전해법에 의하여 형성하도록 하고 있다. A method of 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 method for forming an insulating black matrix. According to the above production method, a black matrix is formed over electrodes other than those corresponding to the individual separated colors. The material of the black matrix forms insulating layers as electrode contact hole zones. Electrically conductive layers are formed on the matrix so that they connect within the same contact hole zone but do not connect between different zones. Then the coloring matter layer is formed by the micelle electrolytic method.
