Display panel and display device

A display device comprising a display panel, wherein the display panel comprising pixel driving circuits provided respectively corresponding to pixel regions and a photosensitive device provided corresponding to a photosensitive region between the pixel regions, and

• wherein the display panel further comprises:
• a substrate;
• a first metal layer provided on a side of the substrate, wherein the first metal layer comprises a shield portion provided corresponding to the pixel region and a reflection portion provided corresponding to the photosensitive region;
• a first semiconductor layer disposed on a side of the first metal layer away from the substrate, wherein the first semiconductor layer comprises a first driving semiconductor portion disposed corresponding to the pixel region and a first light-transmitting semiconductor portion disposed corresponding to the photosensitive region, and the pixel driving circuit comprises the first driving semiconductor portion;
• a second semiconductor layer disposed on a side of the first semiconductor layer away from the substrate, wherein the second semiconductor layer comprises a photosensitive semiconductor portion disposed corresponding to the photosensitive region;
• and
• a third semiconductor layer disposed on a side of the second semiconductor layer away from the substrate, wherein the third semiconductor layer comprises a second light-transmitting semiconductor portion disposed corresponding to the photosensitive region, and the photosensitive device comprises the first light-transmitting semiconductor portion, the photosensitive semiconductor portion, and the second light-transmitting semiconductor portion stacked in sequence.
