1. A display panel, comprising a first substrate and a second substrate provided opposite each other, and a polymer-stabilized liquid crystal layer provided between the first substrate and the second substrate; wherein the first substrate comprises a plurality of sub-pixels defined by intersection of a plurality of gate lines and a plurality of data lines, and each of the plurality of sub-pixels comprises a thin film transistor and a pixel electrode; the plurality of sub-pixels comprise at least one first sub-pixel that emits light from a side of the second substrate away from the first substrate and at least one second sub-pixel that emits light from a side of the first substrate away from the second substrate; the first substrate in a first sub-pixel is provided with a first shielding pattern, and an orthographic projection of the pixel electrode in the first sub-pixel on a plane of the display panel is within a range of an orthographic projection of the first shielding pattern on the first substrate; the second substrate in a second sub-pixel is provided with a second shielding pattern, and an orthographic projection of the pixel electrode in the second sub-pixel on the plane of the display panel is within a range of an orthographic projection of the second shielding pattern on the second substrate;
wherein a shape of a pixel electrode comprises any one or more of block, strip and grid;
wherein the pixel electrode comprises at least one first electrode strip extending along a first direction and at least one second electrode strip extending along a second direction, the at least one first electrode strip and the at least one second electrode strip intersect with each other to form a grid-shaped pixel electrode, and the second direction intersects with the first direction.
