a display panel;

a first polarizer, located on a light-emitting side of the display panel;

a dimming layer, disposed on a side of the first polarizer away from the display panel, wherein the dimming layer comprises at least one first area and at least one second area alternately arranged along a first direction, the first direction is perpendicular to a thickness direction of the dimming layer, the thickness direction of the dimming layer is a direction of the dimming layer pointed to the first polarizer, and the dimming layer comprises:

a first polymer network liquid crystal, located in the first area of the dimming layer and comprising a first polymer network arranged along a second direction and liquid crystal molecules distributed in the first polymer network, wherein the second direction is inclined with respect to the normal line of the first polarizer; and

a second polymer network liquid crystal, located in the second area of the dimming layer and comprising a second polymer network arranged along a third direction and liquid crystal molecules distributed in the second polymer network, wherein the third direction is inclined with respect to the normal line of the first polarizer, and the third direction and the second direction point to opposite sides of the normal line of the first polarizer, the third direction and the second direction are parallel to a plane defined by the first direction and the thickness direction of the dimming layer; and

a second polarizer is located on a side of the dimming layer away from the first polarizer, and a light transmission axis of the second polarizer is parallel to a light transmission axis of the first polarizer;

wherein in a case that the display device is in a first display mode, long axes of the liquid crystal molecules distributed in the first polymer network are arranged along the second direction and long axes of the liquid crystal molecule distributed in the second polymer network are arranged along the third direction.
