An included angle between first and second alignment directions of first and second alignment layers of the first electrically-controlled element is between 75 degrees and 105 degrees. An included angle between third and fourth alignment directions of third and fourth alignment layers of the second electrically-controlled element is between 165 degrees and 195 degrees. A first absorption axis of the first polarizer disposed between the backlight module and the first electrically-controlled element is perpendicular to a second absorption axis of the second polarizer disposed between the first and second electrically-controlled elements. The half-wave plate is disposed between the second polarizer and the second electrically-controlled element. The display panel is disposed on the second electrically-controlled element. A method of driving the display apparatus is provided.
