Abstract: According to one embodiment, an illumination device emits light toward a display panel and includes a transparent substrate having a first main surface opposed to the display panel, a second main surface on a side opposite to the first main surface, and a first side surface connecting the first main surface with the second main surface, and a light source emitting light toward the first side surface. The first side surface has a first intersection surface intersecting a thickness direction from the first main surface to the second main surface.
