Abstract:
1. A liquid crystal display, comprising: a first substrate; a second substrate; a liquid crystal layer arranged between said first and second substrates; thin-film transistors provided at intersecting portions of a plurality of signal lines and a plurality of scanning lines; a pixel electrode formed on the second substrate and having a slit; a common electrode arranged between the second substrate and the pixel electrode and superposed with the pixel electrode; a first polarization film arranged on an opposite side of a side where the liquid crystal layer of the first substrate is arranged; and a second polarization film arranged on an opposite side of a side where the liquid crystal layer of the second substrate is arranged, wherein the liquid crystal layer is driven by applying an electric field to the pixel electrode and the common electrode, the electric field being parallel to a surface of the first substrate and a surface of the second substrate, wherein a reflective display unit and a transmissive display unit are provided in a pixel as a region surrounded by the signal line and the scanning line, wherein a retardation film is arranged between the first polarization film and the liquid crystal layer and arranged only on a position corresponding to the reflective display unit, and wherein the liquid crystal layer has a homogeneous alignment, the transmissive axis of the first polarization film is parallel to a liquid crystal alignment direction, and an angle between a slow axis azimuth of the retardation film and the transmissive axis of the first polarization film lies within a range from 20° or more to 25° or less or a range from 60° or more to 75° or less.
