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.

The pair of substrates includes two or more sets of comb-shaped electrode pairs in which comb tooth portions of each comb-shaped electrode are alternately disposed with each other with a certain space therebetween. One substrate of the pair of substrates comprises a first polarizer. The other substrate of the pair of substrates comprises a second polarizer. A long axis of a comb tooth portion of a first comb-shaped electrode pair among the two or more sets of comb-shaped electrode pairs and a transmission axis of the first polarizer form an angle of substantially 45°. A long axis of a comb tooth portion of a second comb-shaped electrode pair among the two or more sets of comb-shaped electrode pairs and a transmission axis of the second polarizer are in a parallel or orthogonal relationship with each other. The transmission axis of the first polarizer and the transmission axis of the second polarizer are orthogonal to each other. The first comb-shaped electrode pair and the second comb-shaped electrode pair overlap with each other when the surfaces of the pair of substrates are viewed from a normal line direction.
