Abstract: A display device includes a first base substrate including a light-emitting area and a non-light-emitting area around the light-emitting area, a wavelength conversion pattern on the first base substrate in the light-emitting area, and a light-emitting element layer on the wavelength conversion pattern. The light-emitting element layer includes a pixel electrode including a first conductive pattern between the wavelength conversion pattern and the first base substrate, and a second conductive pattern on the wavelength conversion pattern and spaced apart from the first conductive pattern, an organic light-emitting layer on the second conductive pattern, and a common electrode on the organic light-emitting layer.
