A display device may include a first polarizer, a second polarizer, a liquid crystal layer, a light unit, a color filter layer, and a particle set. The second polarizer may overlap the first polarizer. The liquid crystal layer may be positioned between the first polarizer and the second polarizer. The light unit may overlap the liquid crystal layer and may provide first light. The first polarizer may be positioned between the light unit and the liquid crystal layer. The color filter layer may overlap the liquid crystal layer. The second polarizer may be positioned between the color filter layer and the liquid crystal layer. The particle set may include a plurality of particles, may overlap the liquid crystal layer, and may scatter the first light. The second polarizer may be positioned between the particle set and the liquid crystal layer.
