Abstract: A method of manufacturing a color filter according to the present invention is a method of manufacturing a color filter including a plurality of translucent colored layers of different colors on a transparent substrate, including the steps of forming a black matrix layer on the transparent substrate with photolithography, forming one translucent colored layer selected from among the plurality of translucent colored layers with photolithography, and forming a remaining translucent colored layer of the plurality of translucent colored layers with ink-jetting. With this approach, a method of manufacturing a color filter that can attain excellent image quality and can be manufactured at low cost can be provided.

Abstract: An ultrasonic shower cleaning apparatus is disclosed which is capable of efficiently cleaning both surfaces of an article and configured to have a reduced size enabling an installation space thereof to be decreased. A pair of ultrasonic shower cleaning mechanisms each include a nozzle, a disc-shaped ultrasonic transducer arranged so as to face a backward end of the nozzle and an inlet port for a cleaning liquid formed opposite to a side surface of the nozzle. The ultrasonic shower cleaning mechanisms are integrally incorporated in one casing in such a manner that axes of the nozzles cross each other at a predetermined angle. The casing is provided with one inlet branch port connected to the inlet ports of the ultrasonic shower cleaning mechanisms. The casing may have a groove formed therein in which an edge of the article arranged between the two nozzles can be inserted.
