PRODUCTION METHOD FOR PERMANENT FILM FOR OPTICAL MATERIAL, CURED FILM PRODUCED THEREBY, AND ORGANIC EL DISPLAY DEVICE AND LIQUID-CRYSTAL DISPLAY DEVICE USING SAME

摘要

Provided is a production method for a permanent film for optical material in which a photosensitive resin composition is exposed to light in order to remove the photosensitive portion thereof, and the remainder is cured to form a permanent film. The photosensitive resin composition contains (A) a specific crosslinkable polymer, (B) a 1,2-quinone diazide compound and (C) a solvent. The resin is exposed to light by irradiating the photosensitive resin composition with active radiation selected from among g-rays, h-rays, and i-rays through a halftone phase shift mask of which the transmission rate occurring in the phase shifter section thereof is 0.1-50%.
