panel 102 and a signal driver generating a signal for driving a pixel of the liquid crystal panel a method of inspecting a liquid crystal display panel according to a first embodiment of the invention is illustrated in fig8 as illustrated in fig8 the liquid crystal panel 102 is engaged with the probe unit 70 at step 800 upon insertion pads 86 formed at the edge of the liquid crystal panel 102 are engaged with the probe block 72 at step 802 the back light 90 uniformly irradiates a rear surface of the liquid crystal panel 102 more particularly the light generated from the back light 90 passes through a diffuser sheet 94 and the diffused light then passes through a prism sheet 96 such that the light that exits the prism sheet is perpendicularly incident to a rear surface of the liquid crystal panel 102 driving signals are then supplied at step 804 to the panel through probe blocks 72 the camera 42 scans the liquid crystal panel 102 line by line and or area by area and transmits the scanning data to the data processor 50 via a cable 58 at step 806 the data processor 50 processes the scanning data received from the camera to detect defects in the panel the defect map 52.
