Abstract

Provided is a lighting inspection device which enables easy execution of an operation for transforming an inspection stage. Specifically disclosed is a lighting inspection device (100) provided with an inspection stage (30) on which a display panel is set, and a plurality of lighting jigs (33) which are in contact with the display panel set on the inspection stage (30). The inspection stage (30) includes a support post unit (35) and an upper unit (32). The upper unit (32) is movably coupled to the support post unit (35) so as to change the size of the inspection stage (30). An upper lighting jig (33a) and a lower lighting jig (33b) are provided on the inner wall (35a) of the support post unit (35) below the upper unit (32), and a plate (40) that acts as a bridge to the lower lighting jig (33b) is attached to the upper lighting jig (33a).

Description

technical field [0001] The present invention relates to a lighting inspection device. In particular, it relates to an apparatus for inspecting lighting of a liquid crystal panel. [0002] In addition, this application claims the priority based on the JP Patent application 2010-138593 for which it applied on June 17, 2010, The content of this application is incorporated in this specification as a reference. Background technique [0003] A liquid crystal panel, which is a component of a liquid crystal display device (LCD), has a structure in which a pair of glass substrates face each other with a predetermined gap ensured. The liquid crystal panel is a component that does not emit light by itself, and is used in combination with a backlight unit as an external light source. In addition, the liquid crystal panel has a liquid crystal layer between a pair of glass substrates, and a switching element and a pixel electrode are respectively provided on opposing surfaces of the two...
