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>nxd, 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. |
