ABSTRACT:
A color filter is produced through the steps of: forming a layer of a color filter material including a colorant dispersed in a photosensitive resin on a substrate; and pre-baking, exposing and developing the color filter material layer to leave a color filter pattern on the substrate. In the developing step, a developer liquid is applied in the form of a curtain onto the exposed color filter material layer on the substrate, the substrate is allowed to stand in a substantially still state and then the substrate is supplied with an ultrasonic wave projected perpendicularly to the substrate while being in contact with the developer liquid. The ultrasonic wave is preferably uniformized by at least two rotating reflection or diffusion plates before it is projected onto the substrate. As a result, the color filter pattern can be developed with little development irregularity even on a large-size substrate.
