1. A display panel, comprising:
a first substrate;
a second substrate, disposed opposite to the first substrate;
a liquid crystal layer, disposed between the first substrate and the second substrate, and comprising a plurality of liquid crystal molecules;
a first polarizer, disposed at a side of the first substrate away from the second substrate;
a second polarizer, disposed at a side of the second substrate away from the first substrate; the light-transmitting axis of the first polarizer being perpendicular to the light-transmitting axis of the second polarizer;
a first electrode layer, totally disposed on a surface of the first substrate close to the second substrate;
a plurality of second electrodes, disposed at intervals on the first substrate in the second direction; and
a third electrode layer, disposed on a surface of the second substrate close to the first substrate;
wherein when the display panel is in a first display mode, the plurality of liquid crystal molecules rotate in a slanted plane, the slanted plane is parallel to a first direction and a second direction, the first direction is slanted with respect to a thickness direction of the display panel, and the second direction is perpendicular to the thickness direction of the display panel and the first direction;
when the display panel is in the first display mode, voltage applied to the third electrode layer being less than or equal to predetermined threshold voltage, and the electric field formed between the first electrode layer and the plurality of the second electrodes being configured to rotate the plurality of the liquid crystal molecules within the slanted plane;
when the display device is in the second display mode, voltage applied to the third electrode layer being greater than the predetermined threshold voltage, a vertical electric field formed by the third electrode layer, the first electrode layer, and the plurality of second electrodes being configured to deflect the plurality of the liquid crystal molecules in from the slanted plane to a plane perpendicular to the thickness direction of the display panel, and a curved electric field formed by the first electrode layer and the plurality of second electrodes rotates the plurality of the liquid crystal molecules in the plane perpendicular to the thickness direction of the display panel.
