ABSTRACT:
Disclosed is a liquid crystal display device free from display reversal on the screen and capable of being reduced in thickness. A liquid crystal display device of the type in which a transparent electrode and an orientation layer are sequentially formed on the inner side of each of a pair of transparent substrates opposed to each other through the intermediation of a liquid crystal layer and in which a pair of polarizing plates are opposed to each other through the intermediation of the transparent substrates and the liquid crystal layer, wherein a semi-transmissive scattering layer 25 is provided on the outer side of at least one of the pair of polarizing plates, wherein the angle .theta..sub.2 made by the orientation layer 14 of the transparent substrate 4 arranged on the semi-transmissive scattering layer 25 side and the absorption axis of the polarizing plate 7 adjacent to the transparent substrate 4 is set to be 70 to 90 degrees, and wherein the angle .theta..sub.3 made by the absorption axis of the polarizing plate 7 and the optical axis of the semi-transmissive scattering layer 25 is set to be -40 to -70 degrees.
