PURPOSE:To avert the adverse influence on the display grade of an effective picture element part and sensor by simultaneously forming a dye layer pattern within the effective picture element part which is the required part as a color filter and the outside contiguous to the effective picture element part. CONSTITUTION:The photoresist 2 is laminated on a substrate 1 and not only the photoresist 2 in the effective picture element part 7 but also the photoresist 2 on the outside thereof are subjected to pattern exposure through a mask 8. The photoresist 2 is dissolved away by a dissolving liquid and the unnecessary dye layer 3 is simultaneously removed to form the 1st dye layer pattern 4 to the prescribed point in the effective picture element part 7 and the outside thereof. Since the photoresist is patterned even to the outside of the effective picture element part 7, the pattern of the photoresist in the outermost shell part of the effective picture element part 7 is not said to be larger in area than the pattern of the other parts and therefore, the remaining of the intrinsically unnecessary residue of the dye layer in the effective picture element part 7 is obviated. The brightness, color purity and S/N ratio are thereby improved without the adverse influence on the sensor, etc. |
