Abstract

PURPOSE: To flatten the color filter and BS formation at the same time by performing solid black printing on three colors R, G, and B after their printing, and grinding and polishing the surface.
CONSTITUTION: After the printing of the three colors on a glass substrate 5, the set-solid printing 4 is carried out thereupon by screen printing or offset printing, and rotary polishing is carried out by a polishing machine by using abrasive cloth and abrasive grains after drying to grind and polish excessive black ink other than ink in recesses between the colors and the surfaces of the R, G, and B ink layers. Even if the respective colors R, G, and B are irregular in width to have a gap, BS fill the gap, so a light leak is prevented and a color difference at the BS part, specially, a BS color tone defect at a mixed color part of R and G is eliminated; and the top surface is ground and polished to obtain a flat picture element surface, thereby improving the picture quality.
