FIELD: physics.
SUBSTANCE: display has light transmitting apparatus and apparatus for providing interference during reflection of light transmitted through the light transmitting apparatus. The apparatus for providing interference during light reflection has an absorbent material and a movable reflecting layer. The absorbent material lies on part of the light transmitting apparatus. The movable reflecting layer lies on the absorbent material. The absorption coefficient (k) of the absorbent material is lower than the threshold value for light wavelength values in the operating optical range of the apparatus for providing interference during light reflection. The refraction index (n) of the absorbent material increases with increase in the light wavelength in the operating optical range of the apparatus for providing interference during light reflection. The apparatus for providing interference during light reflection are adapted to reflect wide-band white light in the operating optical range.
EFFECT: controlling spectral properties of reflected wide-band white light with high radiation intensity.
