摘要：
A liquid crystal display device includes a liquid crystal panel, a polaroid for polarizing light positioned on a light incident side of the liquid crystal panel, and a polarization analyzer positioned on a light emission side of the liquid crystal panel. The polarization analyzer includes a transparent plate. The transparent plate being arranged at a set angle with a light emission surface of the liquid crystal panel, such that the transparent plate analyzes polarization of light emitted from the light emission surface of the liquid crystal panel. Because the polaroid is used only on the light incident side of the liquid crystal panel, while the transparent plate is used instead of a polaroid on the light emission side of the liquid crystal panel, a reduction in the material cost of the liquid crystal display device can be achieved.
