Abstract

A coating film is formed on the surface of a member during a coating process wherein a coating head and the member are moved relatively. Mixing plural kinds of coating liquid and supplying the resultant mixed liquid to the coating head are carried out substantially simultaneously. The method is used, for example, in producing a color filter of a liquid crystal display device.
