Abstract: A display panel (10) and an electronic device are provided. The display panel (10) includes a base substrate, a low-display-density region (200), a transition region (300) and a high-display-density region (400), the low-display-density region (200), the transition region (300) and the high-display-density region (400) being located on the base substrate. The transition region (300) is located between the low-display-density region (200) and the high-display-density region (400). The low-display-density region (200), the transition region (300) and the high-display-density region (400) are provided with pixel units (101) for emitting light, respectively. A display density of the low-display-density region (200) is less than a display density of the transition region (300), and the display density of the transition region (300) is less than a display density of the high-display-density region (400). Therefore, a clear border between the high-display-density region (400) and the low-display-density region (200) is avoided, and a display effect of the display panel (10) and the electronic device is ensured.
