Abstract
The present invention discloses color pattern manufacturing method comprising the steps of forming a conductive film having an arbitrary pattern on a substrate, forming a colored layer on the conductive film by electrodeposition, and forming a method film having an arbitrary pattern on the colored layer to shield undesirable light transmittance through between the arbitrary patterns of the colored layer, so that the color filter having high quality is made by remarkably simple process.
Claims11
A method of manufacturing a color filter, comprising the steps of:
- forming a conductive film having stripe patterns on an insulative surface of a substrate such that gaps exist between the stripe patterns;
- forming a colored layer on the stripe patterns of the conductive film by electrodeposition such that gaps exist between the stripe patterns of the colored layer;
- forming a transparent conductive film over the stripe patterns of the colored layer and in the gaps;
- and
- forming a metal film having a lattice pattern directly on the transparent conductive film so as to shield light transmittance passing through the gaps between the stripe patterns of the colored layer on the conductive film.
A method of manufacturing a color filter, comprising the steps of:
- forming a conductive film in the form of stripe patterns on an insulative surface of a substrate such that gaps exist between the stripe patterns;
- forming by electrodeposition colored layers on the respective stripe patterns of the conductive film such that gaps exist between the colored layers;
- forming a transparent conductive film over the colored layers and in the gaps between the colored layers;
- and
- forming a metal shield film directly on the transparent conductive film, the metal shield film being in the form of a lattice pattern which covers the gaps between the colored layers to shield against light leakage through the gaps.
