A display device includes a first base substrate, a second base substrate, pixels, a first polarizer, and a second polarizer. The first base substrate includes light transmitting areas and a light blocking area surrounding each of the light transmitting areas. The pixels respectively overlap the light transmitting areas. The first and second polarizers are spaced apart from each other such that the pixels are disposed therebetween. At least one of the first and second polarizers includes a plurality of optical conversion layers, each of which comprises a plurality of lattice wires.
