A display panel is disclosed, which comprises: a first substrate with plural sub-pixel units disposed thereon; a first photo-alignment layer disposed on the first substrate and having at least two different alignment directions corresponding to one sub-pixel unit; and plural metal pads respectively corresponding to the sub-pixel units. When light passes through each sub-pixel, a dark line pattern is exhibited, comprising: a first main dark line disposed at an interface between two different alignment directions of the first photo-alignment layer; and a metal pad pattern corresponding to the metal pad and the first main dark line. Herein, a distance difference between an edge of the first dark line and an edge of the metal pad pattern at the same side is not identical to that between another edge of the first dark line and another edge of the metal pad pattern at another same side.
