Abstract

A method for manufacturing a display device includes: applying a first solution containing (a) and (b) to a substrate containing an oxide, (a) a first functional group capable of being coordinated to the oxide, (b) a second functional group that is cleaved by being irradiated with ultraviolet light to generate any one of an amino group, a carboxyl group, a thiol group, and a selenol group; irradiating at least a part of the first solution applied to the substrate with first ultraviolet light; and applying a solution containing halogenated first quantum dots to a portion irradiated with the first ultraviolet light in the irradiating at least a part of the first solution applied to the substrate to form a first quantum dot layer.
