Patent ID: 8917369

Claim:
A liquid crystal display device comprising a liquid crystal display panel including a color filter substrate, a liquid crystal layer, and an array substrate, wherein, the color filter substrate and the array substrate each include a linearly polarizing plate, and an internal reflectance of the liquid crystal display device is less than 1.0%, wherein, the internal reflectance of the liquid crystal display device is measured by, preparing a sample including a glass substrate, and linearly polarizing plates with refractive indexes of substantially 1.5, the linearly polarizing plates being attached to both surfaces of the glass substrate, being identical to those included in the liquid crystal display panel, and satisfying cross Nicol condition; measuring a reflectance of the sample by using a spectrocolorimeter, the reflectance of the sample being a value combining a normal reflectance and a diffusion reflectance; measuring a reflectance of the liquid crystal display panel in a display region by using the spectrocolorimeter, the reflectance of the liquid crystal display panel being a value combining a normal reflectance and a diffusion reflectance; and subtracting the reflectance of the sample from the reflectance of the liquid crystal display panel.
