Display panel and display device with openings in the transition areas

A display device, comprising a photosensitive device and a display panel, wherein the display panel has a photosensitive area, a transition area surrounding the photosensitive area, and a display area surrounding the transition area and comprises:

• a base substrate comprising a substrate, a first inorganic layer, and a first organic layer stacked in sequence;
• a drive circuit layer disposed on one side of the base substrate, wherein the drive circuit layer comprises a second inorganic layer, the first organic layer is disposed between the first inorganic layer and the second inorganic layer, the second inorganic layer is provided with a first opening in the transition area, the first organic layer is provided with a second opening in the transition area, the first opening is connected to the second opening, a width of the first opening is less than a width of the second opening, and an orthographic projection of the first opening on the first inorganic layer is within an orthographic projection of the second opening on the first inorganic layer;
• a light-emitting layer disposed on one side of the drive circuit layer away from the base substrate, wherein the light-emitting layer covers the transition area and has a disconnected setting in the second opening;
• and
• an encapsulation layer disposed on one side of the light-emitting layer away from the base substrate;
• wherein a distance in a first direction from an edge of any side of the first opening to an edge of the second opening on a same side is greater than 0 and is less than or equal to 2 μm, and the first direction being a width direction of the display panel;
• and
• wherein a distance between one side surface of the first inorganic layer adjacent to the second inorganic layer and one side surface of the second inorganic layer adjacent to the first inorganic layer ranges from 1.5 μm to 3 μm.
