摘要： An interferential optical filter is provided comprising multiple layers each having real and/or imaginary refraction indexes. The values of the real and imaginary indexes depend on the strength of an external electric field.

At least one layer is made of an electro-optical material, which is anisotropic and made from at least one aromatic organic material. The molecules or fragments of molecules of the aromatic organic material have a flat structure. At least part of the layer of the electro-optical material has a crystalline structure with an intermolecular spacing of 3.4±0.3Å along one of optical axes.

This display comprises a reflector (12), a layer of chiral nematic liquid crystal (7) having a front aligning surface (6) facing a light source (1) and a rear aligning surface (8) facing the reflector, and a front polarizer (5, 19). The nematic liquid crystal has an optical retardation (Δnd) of the layer and a distribution of directors, wherein the chiral nematic liquid crystal has a twist angle (Φ) between an alignment direction (15) of the director (13) at the front aligning surface and an alignment direction (16) of the director at the rear aligning surface. The front polarizer is disposed between the layer of chiral nematic liquid crystal and the light source. The front polarizer has a transmission axis forming an angle (α) with the alignment direction of the director at the front aligning surface of the chiral nematic liquid crystal layer. The optical retardation (Δnd) and the angle (α) are defined by the following formulas: α(Φ) = sign(Φ )×(47.0 - 0.4936 |Φ| + 2.6786x10- 3 •Φ 2 ) ± 5, deg, and Δnd(Φ) = -11.674 + 0.1915×|Φ| - 9.8393x10 -4 •Φ 2 + 1.6667x10 -6 •|Φ| 3 ± 0.05, µm, for a value of the twist angle Φ in the range from 180° to 260°.
