Provided is a liquid crystal display device in which color reproducibility and brightness are improved. The liquid crystal display device includes a backlight that emits unpolarized blue light, a quantum rod layer which is provided on an emission side of the backlight and converts some of blue light to red linearly polarized light and green linearly polarized light using multiple quantum rods, a reflective polarizing layer which is provided on a side from which the red linearly polarized light and the green linearly polarized light of the quantum rod layer are emitted, and a liquid crystal panel disposed on a blue linearly polarized light emission side of the reflective polarizing layer, and a long axis direction of the quantum rods in the quantum rod layer and a polarization direction of the blue linearly polarized light emitted from the reflective polarizing layer are parallel to each other. |
