PRODUCTION METHOD FOR ACTIVE ELEMENT SUBSTRATE, ACTIVE ELEMENT SUBSTRATE, AND DISPLAY DEVICE

摘要

A production method for an active element substrate (20), having as the purpose therefor the reduction of production costs of an interlayer insulating film comprising, e.g., an SOG material, said active element substrate (20) forming the interlayer insulating film (23) using a printing method using a plate (50A). The plate (50A) comprises: a main pattern (52) at a position overlapping signal wiring (24) arranged around an opening (6); and a minute linewidth pattern (53) that softens the gradient of an edge section in a printing pattern corresponding to the main pattern (52).
