摘要 |
An object of the present invention is to configure a lighting device to discriminate the front and back sides of a substrate at low costs. In the lighting device of the present invention, a diffuser plate 30 as an optical member 15 includes: a light-transmissive substrate 32; an optical pattern 33 formed on the substrate 32 and applying an optical action to light; and a discrimination pattern 34 configured to discriminate between a first position (normal position) of the substrate 32 and a second position (non-normal position) of the substrate 32 reversed from the first position, formed on a first plane 30a that is a surface of the substrate 32on which the optical pattern 33 is formed , and made of the same material as that of the optical pattern 33. |
