Light emission display panel having electrodes with partially overlapped portions

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.

What is claimed is:  
     
         1 . A light emission display panel having at least two portions comprising a substrate, and 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.    
     
     
         7 . 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.  
     
     
         8 . 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 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.
