Abstract
A method for forming a color filter array includes a step of exposing a photosensitive color filter film, a step of forming a color filter array from the color filter film by developing the color filter film using a developer, and a step of cleaning the color filter array while rotating the color filter array and moving a nozzle for spraying fluid containing liquid and gas above the color filter array in a direction intersecting with an axis of the rotation. The method reduces variation in thickness of a color filter that is generated in the cleaning step.
