Original Abstract Submitted

The present disclosure relates to a display panel inspection device. According to an embodiment of the disclosure, an inspection device includes a loading plate on which a display device is disposed, a reflective plate disposed along a first or second direction to face a display panel of the display device, and a light characteristics inspection control unit controlling a light emitting driving of the display panel and detecting light sensing signals through the display panel to inspect light detection characteristics of the display panel. The light characteristics inspection control unit is configured to inspect the light detection characteristics of the display panel by converting the light sensing signals into light sensing data in units of at least one frame and comparing the light sensing data in units of at least one frame with reference frame data.
