Liquid crystal color screen, equipped with an electro-optical medium (1), two parallel transparent substrates that flank the electro-optical medium, means (4 and 5) for influencing the transmission state of the electro-optical medium, a phosphor layer (6), the at least contains two phosphors, on the first substrate, a radiation source (7) for radiation with a maximum emission at a wavelength λ 1 <360nm on the side of the second substrate and means for transforming the radiation with a maximum emission at a wavelength λ 1 <360nm in radiation with a maximum emission at a wavelength λ 2 > 360nm. |
