Abstract: A display device is provided. The display device includes a display component and a dimming component. The dimming component is disposed on a non-display side of the display component, and provides backlight for the display component. The dimming component includes a plurality of dimming regions, and light emitted from different dimming regions of the plurality of dimming regions is adjusted independently. One of the display component and the dimming component includes a first liquid crystal panel. The first liquid crystal panel includes a first polarizer and a second polarizer that are oppositely disposed, and first liquid crystal molecules located between the first polarizer and the second polarizer. A polarization direction of the first polarizer is perpendicular to a polarization direction of the second polarizer, and when the display device is not powered on, the first liquid crystal molecules are aligned at 45°.
