A novel structure of a device forinspecting liquid crystal display panels. Aliquid crystal display panel is almostcompletely inspected using the device beforean IC chip is mounted and, further, wiringpatterns on external terminals can be inspectedsimultaneously. An air supply inlet (40a) and awide opening part (40b) are provided in theedge part of a holding plate (40), and an elasticsheet (42) is attached so as to close the wideopening part (40b). An IC chip (A) is bondedand fixed to the outer surface of the elasticsheet (42). A flexible circuit board (43) isbonded and fixed to the lower surface of theholding plate (40), and wiring patterns (43a)are provided on the flexible circuit board (43).Connection terminal parts (43b) are providedon the edge parts of the wiring patterns (43a) to which one ends of conductive wires (44) are bonded. The other ends of the conductive wires(44) are bonded to contact terminals (45). The connection terminal parts (43b) and the conductive wires (44) are encapsulated in a moldingbody (46).
