PROBLEM TO BE SOLVED: To provide a vapor deposition mask capable of forming a light-emitting layer having a uniform height with high accuracy and good reproducibility, and a method for manufacturing the same.SOLUTION: A vapor deposition pattern 6 consisting of many independent vapor deposition through-holes 5 is provided in a mask body 2. The vapor deposition through-hole 5 is formed by communicating a small hole part 5a positioned on the side of an evaporation source with a large hole part 5b positioned on the side of a substrate 30 to be vapor-deposited and formed in a shape larger than the opening shape of the small hole part 5a. Accordingly, since the vapor deposition through-hole 5 having an outwardly expanding shape toward the evaporation source can be received an organic material from the evaporation source at a wide angle, a light-emitting layer having a uniform height can be formed with high accuracy.SELECTED DRAWING: Figure 1 |
