<p>PROBLEM TO BE SOLVED: To provide a non-chemical amplifying positive photoresist coating liquid which enables formation of a coating film with uniform thickness all over a substrate, produces no particle and is excellent in storage stability, and to provide a base body for a display device. SOLUTION: The non-chemical amplifying positive photoresist coating liquid is prepared by dissolving an alkali-soluble resin and quinone diazide group-contg. compd. in a mixture solvent comprised of 60 to 98 wt.% propylene glycol monomethylether acetate or 3-methoxy methylpropionate and 40 to 2 wt.%γ-butylolactone. The resultant coating liquid is applied to form a coating film on a glass square substrate to obtain a base body for a display device.</p> |
