The present invention relates to a positive resist composition for forming an organic insulating film of a high-aperture liquid crystal display device containing a binder resin, a photosensitive agent, and a solvent, and a resin represented by the following general formula (1) is used as the binder resin. According to the present invention, the positive resist composition including the binder resin represented by the general formula (1) exhibits a low dielectric constant when forming an organic insulating film of a high opening liquid crystal display device, as well as adhesion to metals and inorganic materials, UV transmittance, residual film rate, and pattern. Formability, chemical resistance, etc. are favorable.n n n <Formula 1>n n n n n n n n n Organic insulating film, positive resist composition, binder resin, high opening ratio, liquid crystal display device |
