Abstract: An inspection apparatus includes: a plurality of support members that support a display panel at a predetermined height; a bending-pressing member that presses a pressing surface of the display panel; a sound wave sensor that senses a sound wave generated from the display panel during a bending inspection process, wherein during the bending inspection process, the bending-pressing member presses the pressing surface of the display panel; and an inspection controller that detects a crack in the display panel using the sound wave sensed by the sound wave sensor.
