PROBLEM TO BE SOLVED: To provide a high-quality image display which has wider viewing angle characteristics and which shows little asymmetry in the lateral viewing angle for the display of a medium tone by controlling the absolute value of the twist angle of an optical compensation film to be smaller than the absolute value of the twist angle of a driving liquid crystal cell. SOLUTION: The normally black mode TN liquid crystal display device is equipped with a driving liquid crystal cell, two polarizing plates and optical compensation film. The driving liquid crystal consists of a pair of transparent substrates basically having electrodes and a nematic liquid crystal layer formed between the substrates, and the liquid crystal layer forms twisted alignment when a voltage is applied. The twisting direction of the twist angle of the optical compensation film is preferably opposite to that of the twist angle of the driving liquid crystal cell. The absolute value of the twist angle of the optical compensation film is preferably smaller than the absolute value of the twist angle of the driving liquid crystal cell. The optical compensation film is obtained by forming a liquid crystal material into a thin film state, heat treating the film to generate desired twisted nematic alignment, and fixing the aligned state.
