摘要： A liquid crystal display with multiplex capability enhanced by decreasing the hysteresis characteristic of the liquid crystal. The hysteresis characteristic of the crystal is reduced by fixing an angle of twist of the liquid crystal molecules in the range of 270 to 315 degrees, by setting a birefringence (.DELTA.N) of the host molecules at less than or equal to 0.14 and by having a crystal layer thickness (d) of less than or equal to 7 .mu.m (.DELTA.n.multidot.d

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.

摘要： A liquid crystal display having a uniform transmittance in the visible light range. The display includes a polarizer and analyzer which correct a non-uniform light transmittance of a liquid crystal layer. This is accomplished by controlling an angle between polarization axes of the polarizer and the analyzer in dependence on the product of a refractive index anisotropy and a thickness of the liquid crystal layer, so that the combined transmittance of the polarizer and the analyzer is a maximum in the wavelength range from 400 nm to 500 nm. When the product is approximately 0.5 .mu.m, the angle is selected in the range from 92 to 110 degrees and when the product is approximately 1.0 .mu.m, the angle is selected in the range from 94 to 120 degrees.
