1. A display apparatus comprising:
an integrated circuit panel; and
a display panel including a first pixel circuit,
wherein the integrated circuit panel comprises:
a first driving circuit;
a data driver configured to output a first input data signal through a first data line;
a switch driver configured to output a first switching signal through a first switch line; and
an error detection driver configured to receive a first output data signal through a first test line,
wherein the first driving circuit is configured to output a first driving signal to the first pixel circuit based on the first input data signal, and output the first output data signal to the error detection driver through the first test line in response to the first switching signal, and
wherein the error detection driver is configured to detect a fault of the first driving circuit based on the first output data signal.
