Abstract
An emissive element layer (65) composed of an organic compound is formed on an anode (61) of an organic EL element or the like, using an evaporation mask (150) in which the width d of an opening (151) and the thickness h of the mask (150) satisfy the relationship h>n×d, where n>1, and more preferably 1<n≦2.5. Accordingly, an EL display device can be obtained in which outspread of an emissive layer material onto an adjacent pixel electrode can be prevented to thereby reduce color mixture.
Claims4
A method of producing an electroluminescence display device comprising an emissive layer for emitting a color formed between an anode and a cathode constituting a pixel electrode, in which provided on said anode is a mask to form said emissive layer, said mask having a thickness h and an opening width d determined between adjacent display pixels which satisfy the relationship h>n×d, wherein n>1.
A method of producing an electroluminescence display device according to claim 11 wherein said mask is formed from a metal or semiconductor.
