The irregular shaped display panel includes a display area and a non-display area surrounding the display area. The method for manufacturing an irregular shaped display panel includes: determining, based on an irregular shaped region on the display panel, boundary pixel units located on a boundary of the irregular shaped region; dividing each boundary pixel unit into at least two pixel division units such that each pixel division unit comprises parts of all sub-pixels of the boundary pixel unit; and determining whether a ratio of an area of each pixel division unit outside the display area to an area of the entire pixel division unit reaches a preset value; if yes, performing a shading process on the pixel division unit. ## Claims ### Claim 1 A method for manufacturing an irregular shaped display panel, the irregular shaped display panel comprising a display area and a non-display area surrounding the display area, the method comprising: determining, based on an irregular shaped region on the display panel, boundary pixel units located on a boundary of the irregular shaped region;
