A method of manufacturing displays, includes at least forming a metal pattern on a surface of an insulating substrate, forming an insulating film on the metal pattern, forming a pattern of a photosensitive resin on the insulating film, and forming a contact hole in the insulating film with the film of a photosensitive resin used as a mask. The forming a contact hole is a dry etching method in which an electric field is generated between a pair of opposed electrodes after an insulating substrate has been mounted on one electrode that includes aluminum in at least a surface thereof. The dry etching method includes forming a contact hole in the insulating film with an outer circumferential portion, which surrounds a region on which the insulating substrate is mounted, of the one electrode covered with an insulating material.
