Abstract: A display device includes a display panel including pixels arranged in a matrix form along first and second directions crossing each other, a backlight unit configured to generate and provide a first light to the display panel, and a color conversion layer. Each pixel includes first and sub-pixels spaced apart from each other. The color conversion layer includes a first sub-color conversion layer overlapping the first sub-pixel and configured to receive the first light and to emit the second light having a wavelength different from that of the first light, and a second sub-color conversion layer overlapping the second sub-pixel, spaced apart from the first sub-color conversion layer and configured to receive the first light and to emit the first light. In a plan view, areas of the first and second sub-color conversion layers are different from each other.
