Abstract: PROBLEM TO BE SOLVED: To make sub-pixel elements free of the effect of subsequent treatment of sub-pixel members and to attain high pixel density. SOLUTION: Areas 10, 12, 15 of red, green and blue color sub-pixel elements are successively formed on a transparent substrate 1 in the entire pixel area 9. After the formation of the separate color sub-pixel elements and before the formation of the next sub-pixel elements, the separate sub-pixel elements and the pixel area are coated with layers 11, 14, 16 of a protective transparent material. The protective layers make the sub-pixel elements free of the effect of subsequent treatment of sub-pixel members when the condition of high temperature curing, a curing agent or curing treatment is used and the advantages of producibility, reliability, yield, cost and throughput are attained.
