A planar light unit is provided that suppresses appearance of a bright line when viewed from the side of the emission surface of the light guide plate. The planar light unit includes a light source, and a light guide plate including an incident surface for receiving light emitted from the light source, an emission surface from which the light introduced through the incident surface is emitted, an opposing surface disposed so as to oppose the emission surface, and a side surface disposed along an outer periphery of the emission surface and the opposing surface. The emission surface has a non-rectangular outer shape, and at least a part of the side surface is formed as a diffusing surface.
