Display screen, display device and method of manufacturing display screen

A display screen, comprising:

• an array substrate, an anode layer, a light-emitting layer and a cathode layer which are stacked in sequence;
• the light-emitting layer comprises a plurality of light-emitting units and a pixel definition layer separating the light-emitting units from each other,
• wherein the pixel definition layer is a transparent layer;
• the cathode layer is provided with a hollow-out area corresponding to the pixel definition layer, the hollow-out area has a semitransparent portion and a light transmitting portion penetrating through the cathode layer, and the light transmitting portion is configured for light emitted to a photosensitive element to pass through, and the semitransparent portion is configured to prevent diffraction generated when the light emitted to the photosensitive element passes through the hollow-out area;
• wherein the light transmitting portion comprises a plurality of through holes penetrating through the cathode layer, and the plurality of through holes are irregularly arranged in the hollow-out area;
• the semitransparent portion is formed between the through holes;
• a projection area of the hollow-out area on the pixel definition layer is equal to or smaller than a projection area of the pixel definition layer;
• the hollow-out area is arranged in one row, in one column or in an array, and a pattern of each hollowed-out area is consistent.
