Abstract
A backlight system includes: a light-emitting section () having a plurality of light sources that emit beams of light at different dominant wavelengths from one another; and an imaging optical system () including a plurality of microlenses () that focus beams of light emitted from the light-emitting section (), the backlight system irradiating a liquid crystal panel with beams of light having passed through the imaging optical system (), the liquid crystal panel including a plurality of pixels arrayed at a predetermined pitch from each other, on the assumption that the pitch at which the pixels are arrayed is denoted as P and the imaging optical system () has an imaging magnification of (1/n), the light sources () being arrayed at a pitch (P) given as P=n×P, the microlenses () being arrayed at a pitch (P) given as P=(n/(n+1))×P.
