<p>The invention covers a liquid-crystal cell having two transparent substrates 1 and 2 arranged at a distance from each other and forming between them a cell space 3 which is filled with liquid-crystal substance 8. Polarizers 5 are arranged on the sides of said substrates facing away from each other while electrodes 6 and 7 are arranged on the sides thereof facing each other. A substrate-side boundary surface of the cell space 3, along which surface the liquid-crystal surface 8 borders, is formed with a plurality of depressions 12 which substantially adjoin each other and, cover the entire boundary surface. Each depression 12 has places of different depth distributed over the extent of its surface, these depths producing light colors which correspond to the total thickness of the liquid-crystal layer 8 present at the respective places. The light colors have at least substantially the entire color spectrum in the region of the surface of a depression 12.</p> |
