Abstract:
1. An OCB liquid crystal display device, comprising: first and second substrates provided to face each other; a liquid crystal layer provided between the first and second substrates; polarizing plates provided on first surfaces of the respective first and second substrates which first surfaces are opposite to respective second surfaces of the first and second substrates which second surfaces face the liquid crystal layer; at least one optical compensation film provided between (i) at least one of the first and second substrates and (ii) a corresponding one of the polarizing plates, the liquid crystal layer including liquid crystal molecules having a spray orientation in a state where no voltage is applied to the liquid crystal layer, a transition occurring to a bend orientation from the spray orientation in response to application of a voltage to the liquid crystal layer, a retardation of the liquid crystal layer obtained while no voltage is applied to the liquid crystal layer falling within ±(a value which is one-tenth of a main wavelength) of a value obtained by adding natural number times the main wavelength to a total retardation of the at least one optical compensation film, and wherein the total retardation of the at least one optical compensation film is within ±10% of a retardation of the liquid crystal layer obtained while an ON voltage is being applied to the liquid crystal layer during display.
