Abstract:
A display panel inspection device comprising: an imaging device polarizing plate (4) that is positioned between a display panel (1) and an imaging device (3); and a light source device polarizing plate (6) that is positioned between a light source device (2) and the display panel (1). The display panel (1) comprises a display panel body (100), a front side polarizing plate (124) that is positioned in front of the display panel body (100), and a rear side polarizing plate (114) that is positioned behind the display panel body (100) and has an absorption axis perpendicular to the absorption axis of the front side polarizing plate (124). The absorption axis of the imaging device polarizing plate (4) is parallel to the absorption axis of the front side polarizing plate (124), and the absorption axis of the light source device polarizing plate (6) is parallel to the absorption axis of the rear side polarizing plate (114).
