Abstract:
1. A liquid crystal display device comprising: a first substrate from which display light is emitted; a second substrate bonded together with the first substrate via a seal material; a liquid crystal layer homogeneously aligned between the first substrate and the second substrate; a pixel electrode provided on the second substrate; a common electrode provided on the second substrate, the common electrode applying an electric field to the liquid crystal layer with the pixel electrode; a pixel including the pixel electrode and the common electrode, the pixel having a transmissive display area and a reflective display area; a first polarizer provided on the first substrate, the first polarizer having a polarization axis parallel to or perpendicular to an initial alignment direction of the liquid crystal layer; a second polarizer provided on the second substrate, the second polarizer having a polarization axis perpendicular to the polarization axis of the first polarizer; and a retardation layer formed of liquid crystal polymer and formed between the liquid crystal layer and the first polarizer only in the reflective display area, the retardation layer having a slow axis that makes an angle of not less than 20° and not more than 25° or not less than 60° and not more than 75° with respect to the polarization axis of the first polarizer, wherein a retardation value of the liquid crystal layer in the reflective display area is set to a value that exceeds a quarter wavelength, and a retardation value of the retardation layer is set to a value that exceeds a half wavelength.
