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 mask 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, wherein the mask has a plurality of openings 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.

2. A mask for manufacturing a light emission panel having a substrate, a plurality of first electrodes on the substrate, a light emission layer on the first electrodes, and plurality of second electrodes, wherein the mask has a plurality of openings each of which has an entire length of the second electrodes are parallely formed, interposing a space having a width corresponding to a width of at least one electrode.
