1. A lighting device, comprising:
a light source that is disposed on one surface;
a first reflective portion that reflects light from the light source toward a first direction that is one direction along the one surface and a second direction that is along the one surface and orthogonal to the first direction; and
a second reflective portion that is disposed on a side of the first reflective portion in the second direction and reflects light from the first reflective portion toward the first direction,
wherein the second reflective portion comprises a reflective surface facing the first direction, and a first end portion facing a direction opposite to the second direction in the reflective surface is disposed more toward the opposite direction compared to a second end portion of the first reflective portion, the second end portion facing the second direction,
wherein the first reflective portion comprises a reflective surface inclined toward the second direction while extending away from the one surface in a separation direction that crosses the one surface, as viewed in a direction opposite to the first direction, and
wherein the first end portion is disposed further toward the second direction compared to an end portion of the reflective surface of the first reflective portion, the end portion facing the one surface.
