Display panel, display device, and manufacturing method of display panel
View Patent ↗The present disclosure discloses a display panel, a display device and a manufacturing method of a display panel, in the field of display technology. The display panel includes a plurality of light-emitting unit groups. A light-transmitting region is between every two adjacent light-emitting unit groups. Each light-emitting unit group includes a light-shielding layer and a light-emitting unit.
