Abstract
A liquid crystal display device includes a pair of substrates opposed to each other; a plurality of pixels for realizing display; and a liquid crystal layer interposed between the substrates and including a liquid crystal region corresponding to each of the pixels, the liquid crystal regions being surrounded by a polymer wall. At least one of the substrates is transparent and includes thereon an optical element for adjusting a transmittance of light therethrough. The optical element corresponds to each of the pixels. The optical element has a transmittance of no greater than 50% with respect to light of at least one wavelength in the range of 250 to 400 nm and has a maximum transmittance of at least 20% with respect to light of a wavelength of more than 400 nm.
