Abstract:
1. An apparatus for manufacturing displays, comprising: a pair of opposed electrodes; and an insulating substrate mounted on one of the two electrodes, the insulating substrate having an insulating film formed on a surface thereof; a voltage applicator configured to apply a voltage between the two electrodes so as to generate an electric field therebetween that causes a contact hole to be formed in the insulating film formed on the surface of the insulating substrate, wherein one of the two electrodes is provided with a protection thereon that is formed of an insulating material, the protection being configured to cover, from an upper side of the insulating substrate, an outer circumferential portion of a region of the one electrode on which the insulating substrate is mounted, and being configured to have a position thereof vertically regulatable.
