The present disclosure provides a display panel and a manufacturing method thereof. The display panel includes a special-shaped display region. The display panel further includes a base substrate and a plurality of pixels on a side of the base substrate, and the plurality of pixels includes an edge pixel with an orthographic projection on the base substrate overlapped with that of an edge of the special-shaped display region on the base substrate. The edge pixel is provided with a light-shielding pattern that divides the edge pixel into a light-shielding region and a light-transmitting region. The edge pixel has a predetermined gray scale and a brightness ratio, the brightness ratio is a ratio of a brightness of the light-transmitting region to a brightness of the edge pixel when an entire region thereof is light-transmitting, and the predetermined gray scale has an exponential function relationship with the brightness ratio.
