Abstract: A display apparatus including a display panel. The display panel includes a pixel generating an image, and a driver chip disposed on the display panel to drive the display panel. The driver chip includes a driving IC, signal bumps, an input bump, and an output bump electrically connected to the input bump. The display panel further includes a printed circuit board including a timing controller, a flexible printed circuit board electrically connecting the display panel and the printed circuit board, signal lines each having one end electrically connected to one of the signal bumps and the other end electrically connected to the timing controller, an input line applying a test signal to the input bump, an output line of which one end thereof is electrically connected to the output bump, and a test resistor connected to the output line.
