Backlight system

Patent Pending A backlight system includes: a light-emitting section (1) having a plurality of light sources that emit beams of light at different dominant wavelengths from one another; and an imaging optical system (3) including a plurality of microlenses (3a) that focus beams of light emitted from the light-emitting section (1), the backlight system irradiating a liquid crystal panel with beams of light having passed through the imaging optical system (3), the liquid crystal panel including a plurality of pixels arrayed at a predetermined pitch from each other, each of the pixels being configured to include a plurality of picture elements corresponding to each separate color, on the assumption that the pitch at which the pixels are arrayed is denoted as P and the imaging optical system (3) has an imaging magnification of (1/n), the light sources (1) being arrayed at a pitch (P 1 ); given as P 1 = n P, the microlenses (3a) being arrayed at a pitch (P 2 ) given as P 2 = (n/(n+1)) P.
