摘要： A display substrate and a display apparatus. The display substrate comprises a display area (100) and a binding area (200) connected to the display area (100). The display area (100) comprises a plurality of data signal lines (71) and K rows and L columns of sub-pixels (P), K and L being both positive integers greater than 1. A plurality of first spaces (R1) are present between K sub-pixel rows; a plurality of second spaces (R2) are present between L sub-pixel columns; each first space (R1) is located between adjacent two sub-pixel rows; and each second space (R2) is located between adjacent two sub-pixel columns. At least one first space (R1) is provided with a first data connection line (68); at least one second space (R2) is provided with at least one second data connection line (74); one end of the first data connection line (68) is electrically connected to one of the data signal lines (71), and the other end is electrically connected to one second data connection line (74); and one end of the second data connection line (74) is electrically connected to the first data connection line (68), and the other end is electrically connected to the binding area (200).
