The first light guide part includes a first A-major surface, a first B-major surface, a first side surface positioned between the first A-major surface and the first B-major surface, and a first hole portion in which the first light source is disposed. The second light guide part includes a second A-major surface, a second B-major surface, a second side surface positioned between the second A-major surface and the second B-major surface, the second side surface facing the first side surface, and a second hole portion in which the second light source is disposed. The first light-modulating member is positioned at an upper side of the first A-major surface.
