    Abstract: A display substrate and a display apparatus are provided. The display substrate includes a base substrate; sub-pixels arranged in an array and on the base substrate; data line groups on the base substrate; each data line group includes data lines, each of which is connected to one column of sub-pixels; data selectors on the base substrate and connected to the data line groups in a one-to-one correspondence; data lines in a same data line group are connected to a same data selector; and data selection signal lines, wherein different data selection signal lines output different data selection signals; and different data lines connected to a same data selector correspond to different data selection signal lines, respectively. The display panel provided may effectively reduce the resistance on the data selection signal lines, thereby reducing the delay of the data selection signals and further improving the charging uniformity of sub-pixels.
