Lighting inspection device for plasma display panel and display panel producing method

摘要

Disclosed here is a light inspection device for performing lighting inspection of a display panel. With the use of the device, a display panel can be tested under the display condition equivalent to that of a finished panel as a product, which improves accuracy of inspection. The light inspection device contains circuit board ( 27 ) having a driving circuit for lighting display panel ( 21 ); conductive chassis ( 25 ) that functions as the ground potential of the driving circuit; and conductive support member ( 26 ) fixed to chassis ( 25 ) for fixing circuit board ( 27 ). Chassis ( 25 ) and support member ( 26 ) are joined via soft metal ( 28 ).
