Abstract: A display apparatus can include a display panel in which pixels, first to gth gate lines, and data lines are provided (where g is a natural number), and link lines provided on a rear surface of the display panel and connected to the data lines provided on a front surface of the display panel. In a display area including the pixels in the front surface, a first stage to an mth stage generating gate signals to be supplied to the first gate line to the gth gate line are provided (where m is a natural number less than or equal to g). A first monitoring line through which a first monitoring signal is output is further connected to the first stage, and the first monitoring line extends to the rear surface through a lateral surface of the display panel.
