Manufacturing method of display panel

The invention discloses a manufacturing method of a display panel, and a light resistance layer is cut by adopting a laser cutting method, so that a through groove is formed in the light resistance layer. The through groove continuously extends from the first surface to the second surface through the side surface, and exposes the first conductive pad and the second conductive pad. And a connecting wire is formed in the through groove, so that the first conductive pad and the second conductive pad are electrically connected. The efficiency of patterning the photoresist layer can be improved by cutting the photoresist layer by adopting a laser cutting method. Compared with the complicated process of first exposing and then developing, the method has the advantages that the process is simpler, the forming efficiency of the side conductive wire can be improved, and the problem of complicated manufacturing process of the display panel is solved. 本申请公开一种显示面板的制作方法，通过采用激光切割的方法切割光阻层，使得光阻层形成通槽。该通槽从所述第一面连续延伸经过所述侧面至所述第二面
