PROBLEM TO BE SOLVED: To provide a liquid crystal display apparatus of OCB type which never causes degradation of image quality even if the environmental temperature is changed. SOLUTION: In the liquid crystal display apparatus of OCB type, a frame inversion drive is carried out to invert the polarities of a white level voltage and a black level voltage in conformity with the polarity of an opposed voltage on the frame-to-frame basis, so that the amplitudes of the black level voltage and the white level voltage decrease in accordance with rise in environmental temperature.
