Abstract: A display panel and a display device are disclosed. The display panel includes a first sub-panel (1), a second sub-panel (2), a drive unit (4) and an image acquisition unit (3). The first sub-panel (1) has a transparent area (S1) and a display area (S2) surrounding the transparent area (S1). The second sub-panel (2) is on a side of the first sub-panel (1) away from a display surface. The drive unit (4) is connected to the second sub-panel (2) and can drive the second sub-panel (2) to move back and forth between positions corresponding to the transparent area (S1) and the display area (S2) of the first sub-panel (1). The image acquisition unit (3) is on a side of the second sub-panel (2) away from the first sub-panel (1), and an orthographic projection thereof on the first sub-panel (1) is within the transparent area (S1). When image acquisition is required, the drive unit (4) drives the second sub-panel (2) to move away from the position corresponding to the transparent area (S1), so that the image acquisition unit (3) can acquire an image. During display, the drive unit (4) drives the second sub-panel (2) to move to the position corresponding to the transparent area (S1) to block the image acquisition unit (3), so that full-screen display of the display panel is achieved.
