Abstract

A display device includes a light-emitting element layer and a light control layer. The light control layer may include a plurality of separated partition wall parts including a partition wall part, a color control part between the partition wall parts, the color control part including quantum dots and a first scattering particle, and a coating layer covering a side of the partition wall part adjacent to the color control part. The coating layer includes at least one selected from a substitution dispersant and a substitution scattering particle, and each of the substitution dispersant and the substitution scattering particle may include at least one substituent selected from an amine group and a carboxyl group. The amine groups and the carboxyl groups included in the coating layer may be different in number from each other.
