PHOTOMASK FOR COLOR FILTER AND METHOD FOR PRODUCING COLOR FILTER, USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a photomask for a color filter capable of forming colored pixels whose four corners are right-angled and a black matrix whose four corners are right-angled even if a close exposure is carried out when colored pixels and a black matrix are formed on a substrate and to provide a method for producing a color filter having colored pixels whose four corners are right- angled and a black matrix whose four corners are right-angled. SOLUTION: Nearly triangular light transmissive parts 5 are extendedly disposed on the four corners of each rectangular light transmissive part 1 or nearly triangular light shielding parts 35 are extendedly disposed on the four corners of each rectangular light shielding part 32. Rectangular colored pixels 3 and a resin black matrix 33 are formed using the resulting photomask for a color filter.
