Method for producing display device

Abstract

A method for producing display devices for forming deposited patterns conforming to pixels on a substrate by means of elongated evaporation sources and a deposition mask having regularly arranged apertures, the method including the steps of arranging the deposition mask and the substrate in such a way that the long sides of the apertures and pixels are parallel to the lengthwise direction of the evaporation sources irrespective of the direction in which the display panel regions are arranged within the substrate; and moving the substrate and the deposition mask relative to the evaporation sources, thereby forming the deposited patterns conforming to the pixels on the substrate.

1 . A method for producing display devices for forming deposited patterns conforming to pixels on a substrate by means of elongated evaporation sources and a deposition mask having regularly arranged apertures, the pixels and apertures having respective long sides and short sides, said method comprising the steps of:
 providing said substrate with parallel long sides and parallel short sides and on which are designated plural display panel regions, each display panel region used to produce a separate display panel, the display panel regions being rectangular in shape and having short sides parallel to the long sides of said substrate;   providing said deposition mask with parallel long sides and parallel short sides corresponding to those of said substrate, said deposition mask having said apertures for said pixels in relationship to each display panel region; and   providing said evaporation sources such that lengths thereof match the lengths of said short sides of said substrate and said deposition mask,   wherein,
 said deposited pattern is a pattern of organic light-emitting layer. 
   
     
     
         2 . The method for producing display devices as defined in  claim 1 , wherein more than one of said display panel region are arranged within the substrate. 
     
     
         3 . The method for producing display devices as defined in  claim 1 , wherein more than one of said display panel regions, in rectangular shape, are arranged within said substrate in such a way that short side of said more than one of said display panel regions is parallel to the direction in which said substrate moves. 
     
     
         4 . The method for producing display devices as defined in  claim 2 , wherein said display panel region is rectangular and at least one of said display panel regions is arranged within said substrate in such a way that short side of said at least one of said display panel regions is parallel to the direction in which said substrate moves.
