Display device

A display device comprising:

• a light unit;
• a color conversion panel on the light unit;
• a display panel between the light unit and the color conversion panel, the display panel comprising transistors;
• and
• column spacers between the transistors and the color conversion panel, the column spacers overlapping the transistors,
• wherein the color conversion panel comprises:
• a substrate;
• color conversion layers between the substrate and the display panel and including semiconductor nanocrystals;
• a transmission layer between the substrate and the display panel;
• and
• polarization layers between the color conversion layers and the display panel and between the transmission layer and the display panel,
• wherein the light unit is configured to emit light having a first wavelength of about 400 nm to about 500 nm, and
• the column spacers are configured to absorb light having the first wavelength.
