1. In order to produce a polariser and a LCD element comprising such a polariser, this invention uses at least one birefringent layer with anisotropic absorption, wherein said layer exhibits at least one refraction index which increases together with the wavelength of the light to be polarised, said layer having more precisely an abnormal dispersion.
2. A longitudinal acoustic mode for which normal dispersion is adjusted in the first resonator and abnormal dispersion is adjusted for the second resonator by selecting the material and the relative layer thicknesses, is able to propagate in the resonators, thus making it possible to improve especially the power compatibility of the filter at the higher frequency edge of the passband thereof.
