Abstract
1385448 Modulating light WERK FUR FERNSEHELEKTRONIK VEB 9 April 1973 [13 Oct 1972] 16847/73 Heading H4F An electro-optic display cell comprises a layer 4 of liquid crystal material disposed between a transparent substrate 1 bearing a transparent electrode 3 and a substrate 2 bearing a reflective layer 6, e.g. of aluminium, covered by a transparent electrode layer 7. Layer 6 is thereby prevented from reacting with the liquid crystal material while simultaneously being closely adjacent thereto to reduce parallax. Electrode 3 is shaped, e.g. in a seven segment display, and layers 6 and 7 are shaped to the outer contour of the electrode 3.
