Patent ID: 7088409

Claim:
A liquid crystal display constructed by a first substrate, a second substrate, and a liquid crystal layer, said liquid crystal layer being sandwiched between said first substrate and said second substrate, said second substrate having a pixel electrode and a common electrode, an electric field substantially parallel with surfaces of said substrates being applied between said pixel electrode and said common electrode to drive said liquid crystal layer, a reflective display unit and a transmissive display unit being formed in one pixel, a first polarization film and a second polarization film being arranged outside of the first substrate and the second substrate, transmissive axes of said first polarization film and said second polarization film perpendicularly crossing each other, and either one of said transmissive axes of said first polarization film and said second polarization film being parallel with a liquid crystal alignment direction, wherein said display has a retardation film in a portion corresponding only to said reflective display unit, said retardation film is arranged between said first polarization film and said liquid crystal layer, a retardation of the liquid crystal layer of said reflective display unit is equal to a quarter wave, and a retardation of said retardation film is equal to a half wave.
