LIQUID CRYSTAL DISPLAY UNIT

摘要

A vertical alignment (VA)-mode liquid crystal display unit comprising, arranged in layers in the order mentioned, a low-refractive-index layer, an output-side polarizer, at least one sheet of biaxial optical anisotropy, a liquid crystal cell and an input-side polarizer, wherein (1) n<SUB>x</SUB>>n<SUB>y</SUB>>n<SUB>z</SUB> is satisfied (n<SUB>x</SUB>, n<SUB>y</SUB>: in-plane main refractive index of the whole optical anisotropy, n<SUB>z</SUB>: thickness-direction main refractive index), (2) the low-refractive-index layer consists of aero-gel with a refractive index of up to 1.37, and (3), when no voltage is applied with the biaxial optical anisotropy and the liquid crystal cell stacked by excluding the output-side polarizer and the input-side polarizer, retardation R<SUB>0</SUB> when a light with a wavelength of 550nm is incident from a normal direction and retardation R<SUB>40</SUB> when a light with a wavelength of 550nm is incident from a direction of a polar angle of 40 degrees satisfy the relation | R<SUB>40</SUB> - R<SUB>0 </SUB>| = 35 nm.
