Abstract

A light emission display panel has a substrate, a plurality of first electrodes on the substrate, a light emission layer on the first electrodes, and a plurality of second electrodes. Each of the second electrodes has a form of a strip film in which partially overlapped portions are provided.

Claims

1. A light emission display panel having at least two portions comprising a substrate, a plurality of first electrodes on the substrate, a light emission layer on the first electrodes, and a plurality of second electrodes, wherein

each of the second electrodes has a form of a strip film in which partially overlapped portions are provided.

2. 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 a line corresponding to each of the second electrodes, interposing a predetermined space between adjacent openings, 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 the first electrode;

forming a film in each opening by a material for the second electrode;

shifting the mask by a pitch corresponding to said space; and

forming a film in each opening of the shifted mask, whereby the second electrodes are formed.

3. The method according to claim 2 wherein adjacent lines are offset by at least a distance equal to a length of the opening in an extending direction of the second electrode.

4. The method according to claim 2 wherein the space is smaller than a length of the opening in the extending direction of the second electrode so as to overlap both ends of the film with an adjacent film.

5. The method according to claim 4 wherein a distance between adjacent openings is a multiple of integer of the space.

6. 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 each of which has an entire length of the second electrode are parallely formed, interposing a space having a width corresponding to a width of at least one electrode;

mounting the mask on the light emission layer so that each of the openings corresponds to the first electrode;

forming a film in each opening by a material for the second electrode;

shifting the mask by a pitch corresponding to said space; and

forming a film in each opening of the shifted mask, whereby the second electrodes are formed.
