Abstract:
A liquid crystal display device according to the present invention includes: a vertical alignment liquid crystal layer; first and second electrodes arranged on one surface of first and second substrates to face the liquid crystal layer; and first and second alignment films arranged on the first and second electrodes, respectively, in contact with the liquid crystal layer. The first alignment film has been subjected to an optical alignment treatment by obliquely irradiating a first alignment film material, having a photosensitive wavelength within the wavelength range of 250 nm to 380 nm, with light including the photosensitive wavelength. The device further includes: a metal layer arranged between the first alignment film and the first substrate; and a first resin layer arranged between the metal layer and the first alignment film. The first resin layer has an optical property that attenuates the intensity of light, which has been incident on the first resin layer and then reflected from the metal layer, to 60% or less at the photosensitive wavelength.
