摘要： A display apparatus includes an array substrate; a counter substrate facing the array substrate; a liquid crystal layer between the array substrate and the counter substrate; at least one optical compensation film between the array substrate and the counter substrate, extending throughout a display area of the display apparatus; a control electrode between the array substrate and the counter substrate, extending throughout the display area of the display apparatus; and a back light configured to provide light for image display. The liquid crystal layer in a dark state has a first phase retardation. Under control of the control electrode, the at least one optical compensation film gives a second phase retardation when the liquid crystal layer is in the dark state. A sum of the first phase retardation and the second phase retardation is substantially same as an integral multiple of a wavelength of light emitted from the back light.
