Abstract
PURPOSE:To obtain a color filter having a high contrast and excellent smoothness by providing an active film layer consisting of a metal oxide on a transparent substrate, providing a thin metallic film pattern and ink layer thereon, coloring the active film layer and sealing said layer, then removing the ink layer. CONSTITUTION:An alumina sol is spray coated on one face of a transparent glass plate 1 and is dried and calcined, following which the active film layer 2 having about 2mum layer thickness is formed thereon. A resist having UV ray sensitivity is coated on this glass plate 1 and is exposed to a prescribed pattern 4. After the resist in the part where a black matrix is required is removed, the glass plate is immersed into a catalyst liquid. The plate is immersed in an electroless plating bath and is subjected to nickel plating. The resist film is removed upon ending of the plating. Red, green, and blue colored inks are thereafter printed in stripe patterns of 0.35mm width on the plate and are heated to migrate the coloring agents to the active film layer 2. The plate is then immersed in boiling water to seal the active film layer 2. The ink layers 3 are removed by acetone. The color filter having the high contrast and excellent smoothness is thereby obtd. with fewer stages.
