Abstract: A chip-on-film package includes a base film, a test line, and an integrated circuit chip. The base film includes a bent area in which a bending occurs. The test line is disposed on the base film, and at least a portion of the test line is overlapped with the bent area. The integrated circuit chip is disposed on the base film and includes a first terminal and a second terminal. The first terminal is connected to one end of the test line to output a first signal and the second terminal is connected to the other end of the test line to receive a second signal. The integrated circuit chip detects whether a crack occurs in the bent area based on a difference value in signal characteristics.
