Abstract:
The purpose of the present invention is to suppress irradiation of light toward an undesired region. An antistatic device (10) of the present invention is provided with a light source (11), a light guide plate (20), and a light shielding member (30). The light shielding member (30) is provided between the light source (11) and an incident surface (20a) of the light guide plate (20).
