Abstract: A display apparatus includes a backlight component, a light adjusting component, a display panel, and a first polarizing film. The backlight component is configured to generate polarized light. The light adjusting component is disposed on one side of the backlight component, and is configured to deflect or not deflect polarized light generated by the backlight component. The first polarizing film is disposed between the light adjusting component and the display panel. In the display apparatus) provided in this application, when the polarized light obtained after passing through the light adjusting component passes through the first polarizing film, if a vibration direction of the polarized light is consistent with a transmission direction of the first polarizing film, the polarized light can be transmitted. If the vibration direction of the polarized light is perpendicular to the transmission direction of the first polarizing film, the polarized light cannot be transmitted.
