Display panel and display device

A display device, comprising:

• a display panel, comprising:
• a light-transmitting area, a main display area, a first transition display area, and a first wiring area, wherein the first transition display area is located on both sides of the light-transmitting area in a first direction, the first wiring area is located on a side of the first transition display area and the light-transmitting area in a second direction, the main display area is located on a side of the first wiring area away from the first transition display area and the light-transmitting area, and the first direction and the second direction intersect with each other;
• a first light-emitting unit located in the light-transmitting area;
• a first pixel driving circuit located in the first transition display area for providing a driving current to the first light-emitting unit;
• a first signal line extending in the second direction, wherein at least a part of the first signal line is located in the first transition display area for providing a potential signal to the first pixel driving circuit;
• a second signal line extending in the second direction, wherein at least a part of the second signal line is located in the main display area for providing a potential signal to the pixel driving circuit in the main display area;
• and
• a third signal line extending in the first direction, wherein at least a part of the third signal line is located in the first wiring area, and the third signal line is connected to the first signal line and the second signal line through via holes, respectively;
• a camera directly facing the light-transmitting area of the display panel.
