Claim 2:
3. A method for manufacturing a display device, the method comprising steps of:
preparing a substrate on which a display region which displays an image configured with a plurality of pixels is formed, the substrate including a first pixel electrode included in one of the plurality of pixels, the first pixel electrode being provided over a surface of the substrate, and a second pixel electrode included in another one of the plurality of pixels, the second pixel electrode being provided over the surface of the substrate, and a first convex portion provided adjacent to the first pixel electrode and a second convex portion provided adjacent to the second pixel electrode, each of the first convex portion and the second convex portion is provided in the display region;
disposing a first vapor deposition mask having an opening in a region of the substrate facing the first pixel electrode and the first convex portion and having a shielding portion in a region facing the second convex portion;
forming a first organic layer including a layer exhibiting a first emission color to cover the first pixel electrode and the first convex portion and not to cover the second convex portion by a vapor deposition process through the first vapor deposition mask;
disposing a second vapor deposition mask having an opening in a region of the substrate facing the second pixel electrode and having a shielding portion in a region facing the first convex portion and the second convex portion on the substrate; and
forming a second organic layer including a layer exhibiting a second emission color to cover the second pixel electrode and not to cover the first convex portion and the second convex portion by a vapor deposition process through the second vapor deposition mask, wherein
the apex of the first convex portion is formed to be located farther from the surface of the substrate than the apex of the second convex portion,
the first vapor deposition mask is disposed on the substrate by using the second convex portion as a spacer, and
the second vapor deposition mask is disposed on the substrate by using the first convex portion as the spacer.
