Zusammenfassung:	A xenon lamp or a fluorescent lamp has been used for a backlight of a lighting inspection apparatus. A first object of the present invention is to realize an inspection apparatus using a small backlight constituted of a dimmer plate as well as a fluorescent lamp, thus to miniaturize the inspection apparatus for a display panel. A second object of the present invention is to propose an inspection method for a display panel, which uses a dimmer plate autonomously adjusting light. An apparatus for inspecting a display panel includes: a support structure disposing thereon a display panel to be inspected; a light source; and a dimmer plate with a characteristic modulating a light transmission characteristic in accordance with an intensity of light incident thereonto, the dimmer plate being disposed between the support structure and the light source, wherein light emitted from the light source is made to transmit through the dimmer plate, then made incident onto the display panel disposed on the support structure.
