Patent ID: 6921309

Claim:
A method for manufacturing a light emission display panel having a substrate, a plurality of first electrodes on the substrate, a light emission layer on the first electrodes, and a plurality of second electrodes, comprising the steps of: providing a mask in which a plurality of openings are formed along lines corresponding to the second electrodes, interposing a predetermined space between every two adjacent openings along the lines, each of the openings having a width equal to the width of the second electrodes; mounting the mask on the light emission layer so that each of the openings corresponds to at least one of the first electrodes; forming a film in each opening by a material for the second electrode; shifting the mask by a pitch smaller than said space or shorter than a length of each opening; and forming a film in each opening of the shifted mask, whereby the second electrodes are formed, wherein adjacent openings are spaced apart from each other by at least a distance equal to a length of the opening in an extending direction of the second electrode.
