Manufacturing method of display panel and display panel

The invention discloses a manufacturing method of a display panel and the display panel. The manufacturing method of the display panel comprises the following steps: providing a substrate; forming an amorphous silicon layer on the substrate; and performing excimer laser annealing crystallization on the amorphous silicon region corresponding to each driving transistor in the same mode. According to the embodiment of the invention, the display uniformity of the display panel is improved. 本发明公开了一种显示面板的制作方法及显示面板。显示面板的制作方法包括：提供一基板；在所述基板上形成非晶硅层；对每一驱动晶体管对应的非晶硅区域以相同的方式进行准分子激光退火晶化。本发明实施例提高了显示面板的显示均匀性。
