A display device including quantum rods is provided. The display device includes a light source generating light, a lightguide plate changing a path of the light generated from the light source and outputting the light to a front surface, a first polarizing plate arranged on top of the lightguide plate and generating first polarized light, a liquid crystal panel arranged on top of the first polarizing plate and displaying an image by using the first polarized light, a second polarizing plate arranged on top of the liquid crystal panel and generating second polarized light, and a quantum rod layer arranged on top of the second polarizing plate, divided into a plurality of pixels, and containing quantum rods in at least one of the pixels. A polarizing axis of the second polarized light is perpendicular to a polarizing axis of polarized light emitted by the quantum rod layer.
