Array substrate, display panel, display apparatus and preparation method therefor

An array substrate, comprising:

• a base substrate;
• and
• at least one pixel element on one side of the base substrate, each of the at least one of pixel element comprises:
• a thin film transistor, an electroluminescence structure and a light-shielding structure between the thin film transistor and the base substrate;
• wherein, the thin film transistor comprises a drain and an active layer;
• at least one insulation layer on one side of the base substrate near the at least one of pixel element;
• wherein a surface of the at least one insulation away from the base substrate comprises a recessed portion, and the electroluminescence structure is in the recessed portion;
• each of the at least one of pixel element comprises a light-emitting area, and a circuit area adjacent to the light-emitting area;
• wherein the thin film transistor is in the circuit area, and the electroluminescence structure is in the light-emitting area;
• the active layer is between the base substrate and the at least one insulation layer;
• the drain is on one side of the at least one insulation layer away from the base substrate, and the drain covers at least a portion of a sidewall of the recessed portion for preventing light emitted by the electroluminescence structure from being incident on the active layer;
• wherein the electroluminescence structure comprises a first electrode configured to drive the pixel element and one of the light-shielding structure and the active layer is at a same layer as the first electrode.
