Abstract: The present disclosure provides a display substrate and a display device. Auxiliary signal lines crossed with initialization signal lines are arranged, and first via holes are formed in the intersections of the initialization signal lines and the auxiliary signal lines, so that the initialization signal lines and the auxiliary signal lines are correspondingly electrically connected by means of the first via holes, and the initialization signal lines and the auxiliary signal lines which are electrically connected are connected in parallel, which is equivalent to the initialization signal lines being connected to a resistor in parallel; thus, the equivalent resistance of the initialization signal lines can be reduced. Since the longer initialization signal lines have a larger number of first via holes, the longer initialization signal lines can be connected to more resistors in parallel, thereby reducing delay of signal transmission. Further, the display substrate in the present disclosure can be applied to a large-size display device, and the display uniformity is improved.
