PURPOSE:To flatten the picture element patterns of color filters by constituting the surface protective material of a specific org. high polymer contg. styrene and photodimerization type functional group. CONSTITUTION:This surface protective material consists of the org. high polymer which has the unit of the styrene and the unit contg. the functional group of the photodimerization type, is expressed by formula I and has 500 to 10,000 weight average mol. wt. In the formula, R1 and R2 denote a hydrogen atom, methyl group; R3 denotes a monovalent org. group contg. the functional group of the photodimerization type; Ar denotes a phenyl group or naphthyl group; (m) denotes 0, 1 integer; (n) denotes >=1 integer. Thus, the ideally flat surface protective layer is applied on the color filters and further heat resistance, chemical resistance and transparency are obtd. |
