Claim 1:
2. The manufacturing method of the display device according to claim 1, further comprising:
after removing the first patterned resist,
forming a second organic layer above the first lower electrode, on the second lower electrode and on the upper portion of the partition, the second organic layer including a second light-emitting layer and being in contact with the second lower electrode at the second aperture;
forming a second upper electrode on the second organic layer;
forming a third transparent layer on the second upper electrode, the third transparent layer being formed of a third organic material;
forming a fourth transparent layer on the third transparent layer, the fourth transparent layer being formed of a fourth organic material different from the third organic material;
forming a second sealing layer on the fourth transparent layer, the second sealing layer being formed of a third inorganic insulating material;
forming a second patterned resist on the second sealing layer, the second patterned resist covering a first portion of the second sealing layer above the second lower electrode and a second portion of the second sealing layer above a third part of the upper portion of the partition, and the second patterned resist exposing a third portion of the second sealing layer above the first lower electrode and a fourth portion of the second sealing layer above a fourth part of the upper portion of the partition;
removing the third portion of the second sealing layer to expose a portion of the fourth transparent layer by a fourth dry etching;
removing the portion of the fourth transparent layer to expose a portion of the third transparent layer by a fifth dry etching using the oxygen plasma;
removing the portion of the third transparent layer to expose a portion of the second upper electrode by the fifth dry etching;
removing the portion of the second upper electrode to expose a portion of the second organic layer by a second wet etching;
removing the portion of the second organic layer by a sixth dry etching using the oxygen plasma, and
removing the second patterned resist, wherein

the first light-emitting layer emits a light of a first color, and
the second light-emitting layer emits a light of a second color different from the first color.
