Abstract

A method and apparatus for making contoured planarizing or protective layers for color filters for liquid crystal display panels. A transfer layer is formed on a collector device having a contoured surface. A plurality of colored ink patterns is formed on the transfer layer thereby forming the multicolor image that will become the color filter. This multicolored image is then transferred to the substrate so that the transfer layer in effect becomes a top protective layer or planarizing layer. The contoured surface on the collector device is imparted to the planarizing layer.
