BACKLIGHT UNIT, ELECTRO-OPTICAL DEVICE, AND ELECTRONIC APPARATUS |
摘要 |
A direct-type backlight unit includes: an arrangement surface on which a plurality of light sources are arranged; and a plurality of reflecting surfaces that are formed at a plurality of ends of the arrangement surface and reflect light emitted from the plurality of light source. Light emitted from the light sources and light reflected from the plurality of reflecting surfaces irradiate to a radiation area surrounded by the plurality of reflecting surfaces. The plurality of reflecting surfaces are inclined at an angle that is smaller than 90 degrees with respect to an extension surface of the arrangement surface that extends toward the outside of the reflecting surface. The plurality of reflecting surfaces include reflecting surfaces having a large inclination angle and reflecting surfaces having an inclination angle that is smaller than the large inclination angle. The light sources that are arranged along the reflecting surfaces having the large inclination angle are closer to the edge of the radiation area than the other light sources that are arranged along the reflecting surfaces having the small inclination angle, in a plan view of the radiation area.
