Display panel, preparation method thereof, and display apparatus

A display panel, comprising:

• a first substrate and a second substrate disposed oppositely, and a liquid crystal layer sandwiched between the first substrate and the second substrate, wherein
• the second substrate comprises a second base substrate and a shielding layer, an array structure layer, an insulating layer and a reflective layer which are sequentially disposed on the second base substrate, wherein the array structure layer comprises a gate electrode layer, and the gate electrode layer comprises a plurality of gate lines;
• the shielding layer comprises a plurality of groups of light shielding units sequentially arranged along a first direction, each group of the light shielding units comprises a plurality of independent sub-light shielding units sequentially arranged along a second direction, wherein
• the first direction intersects with the second direction;
• the reflective layer comprises a plurality of reflective units arranged in an array along the first direction and the second direction, the plurality of reflective units form a plurality of reflective rows and a plurality of reflective columns, a space area between adjacent reflective columns forms a first space area, and a space area between adjacent reflective rows forms a second space area;
• and
• the first space area comprises a first sub-region and a second sub-region, an orthographic projection of the first sub-region on the second base substrate is overlapped with an orthographic projection of a spacing area between two adjacent sub-light shielding units in each group on the second base substrate, and an orthographic projection of the second sub-region on the second base substrate is not overlapped with an orthographic projection of a space area between two adjacent sub-light shielding unit in each group on the second base substrate.
