Abstract:
1. A liquid crystal display device, comprising: a pair of substrates; a polarizing plate arranged on at least one of the pair of substrates; a liquid crystal layer arranged between the pair of substrates; and a group of electrodes formed on at least one of the pair of substrates, for applying an electric field to the liquid crystal layer, wherein at least one of the pair of substrates has a uniaxial absorption an isotropy; wherein the polarizing plate includes a polarizing plate protective film and an adhesive layer for bonding at least one of the pair of substrates and the polarizing plate; wherein at least one of the pair of substrates, the polarizing plate protective film, and the adhesive layer includes a pigment added thereto; wherein the at least one of the pair of substrates, the polarizing plate protective film, and the adhesive layer which includes the pigment added thereto has a dichroic ratio of at least 2; wherein the at least one of the pair of substrates, the polarizing plate protective film, and the adhesive layer which includes the pigment added thereto has a region where an absorbance of an absorption axis is at least 0.2; and wherein a difference of absorbances between an absorption axis and a transmission axis is at least 0.1, which is shown by the at least one of the pair of substrates having the uniaxial absorption anisotropy.
