Display device and method for manufacturing display device

A method for manufacturing a display device, the method comprising:

• forming a first light-emitting layer, configured to emit light in a first color, in at least a first region on a substrate by using a first solution including a first light-emitting material and a first solvent;
• forming a second light-emitting layer, configured to emit light in a second color different from the first color, in at least a second region different from the first region on the substrate by using a second solution including a second light-emitting material and a second solvent in which a solubility of the first light-emitting material is less than a solubility of the first light-emitting material in the first solvent, forming the second light-emitting layer being performed after forming the first light-emitting layer;
• and
• forming a third light-emitting layer, configured to emit light in a third color different from the first color and the second color, in at least a third region different from the first region and the second region on the substrate by using a third solution including a third light-emitting material and a third solvent in which a solubility of the second light-emitting material is less than a solubility of the second light-emitting material in the second solvent, forming the third light-emitting layer being performed after forming the second light-emitting layer,
• wherein the first light-emitting layer and the second light-emitting layer emit light in different regions, and
• the third light-emitting layer emits light in a region different from regions of the first light-emitting layer and the second light-emitting layer.
