Abstract:
1. A liquid crystal display device, including: a lower substrate, an upper substrate opposed to the lower substrate, a first polarizer assembly located on a surface of the lower substrate, a second polarizer assembly located on a surface of the upper substrate and a liquid crystal layer located between the upper substrate and the lower substrate; the first polarizer assembly including a first polarizing plate and a first optical retardation thin film; the second polarizer assembly including a second polarizing plate and a second optical retardation thin film; wherein, the first polarizer assembly further includes a first wave plate; the second polarizer assembly further includes a second wave plate, wherein, the thickness of liquid crystal in the liquid crystal layer is determined according to optical path differences generated by each of the first wave plate and the second wave plate and the wavelength of an incident light, and wherein the relationship between thickness of liquid crystal in the liquid crystal layer and the optical path differences generated by each of the first wave plate and the second wave plate is that wherein n e and n o are refractivities of liquid crystal to an I light and an o light, respectively, λ is the wavelength of the incident light, the wavelength range of the incident light is between 400 nm and 800 nm, and d is the thickness of liquid crystal.
