Abstract
A display apparatus includes a backlight, a first polarizer, a light controlling panel, a second polarizer, a display panel, and a third polarizer sequentially arranged along a direction. A transmission axis of the first polarizer and a transmission axis of the second polarizer are substantially parallel, and the transmission axis of the second polarizer and a transmission axis of the third polarizer are substantially perpendicular. A set of the first polarizer, the light controlling panel, and the second polarizer has a transmittance, and the transmittance has a maximum value when the light controlling panel is not enabled.
