摘要： A backlight system (30) includes a light emitting section (31) and an imaging optical system. The imaging optical system includes a first microlens array (MLA1) and a second microlens array (MLA2). The lenses (1A) separates the beams of light emitted from the light emitting section (31) by RGB, and causes them to be converged at a pitch same as a pitch at which the picture elements are arrayed. The lenses (2A) are provided in one-to-one correspondence to the picture elements such that the lenses (2A) have their respective focal points at positions onto which beams of light having passed through the lenses (1A) are converged. The lenses (2A) thus deflect the beams of light which have passed through the lenses (1A) in a substantially vertical direction with respect to the display surface of the liquid crystal panel.
