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.
Technique et appareil de formation de couches de planarisation ou de protection profilées pour filtres colorés destinés à des écrans à cristaux liquides. On crée une couche de transfert sur un collecteur ayant une surface profilée. On trace sur la couche de transfert, à l'encre de couleur, plusieurs motifs qui forment l'image polychrome devant constituer le filtre coloré. Cette image est ensuite transférée sur le substrat de telle façon que la couche de transfert fasse office de couche supérieure de protection ou de couche de planarisation. La surface profilée du collecteur est transmise sur la couche de planarisation.
