Abstract: The present disclosure provides a display panel and a display device including the display panel. The display panel has a display region including a first display region and a second display region, and the first display region has a smaller sub-pixel density than the second display region. Light-shielding structures are arranged in the first display region, and one light-shielding structure overlaps a light-emitting region of at least one first sub-pixel. The light-shielding structure group constituted by the light-shielding structures includes main and auxiliary light-shielding structures having the same shape. When viewed from the top at the same viewing angle, the auxiliary light-shielding structure is equivalent to a structure obtained by rotating the main light-shielding structure by a certain angle in a plane where the main light-shielding structure is located. With this design, a light diffraction phenomenon is alleviated and the imaging quality of the under-screen optical device is improved
