Abstract
A light reflector and a planar light source achieving high average luminance and little luminance unevenness are provided. In a light reflector including a reflector and a reflective chevronwise partition plate projecting in a shape of a chevron from the reflector, a reflective planar partition plate is provided, connected to a peak section of the chevronwise partition plate such as to project upwards from the peak section. The chevronwise partition plate and the planar partition plate are disposed between adjacent linear light sources.
