Display device

The display device includes: a plurality of sub-pixels including first and second electrodes extending in a first direction and spaced apart in a second direction, and a plurality of light emitting elements on and electrically connected to the first and second electrodes; a bank layer extending around a region in which the light emitting elements are arranged; and a plurality of wavelength conversion layers and a plurality of light transmission layers in a region defined by the bank layer. The plurality of sub-pixels includes: a first sub-pixel including a first wavelength conversion layer overlapping the light emitting element in a region defined by the bank layer; and a second sub-pixel including a second wavelength conversion layer, a third wavelength conversion layer including wavelength conversion particles different from the wavelength conversion particles of the second wavelength conversion layer, and a first light transmission layer, each of the second wavelength conversion layer, the third wavelength
