The ratio of a second resistance value to a first resistance value is less than the ratio of the average line width of the second voltage signal lines (GNvgh) to the average line width of the first voltage signal lines (Evgh). By means of the display substrate, a difference in a signal delay time brought about by different resistances of different connecting wirings can be reduced.
