Abstract

PURPOSE: To achieve the higher contrast of liquid crystal display by applying the voltage at which the opening angle of optical fiber aggregate and maximum visual angle producing contrast in non-selected display regions nearly coincide and time- dividedly driving the device.
CONSTITUTION: The device is constituted by a front face polarizer 13, optical fiber aggregate 14, patterned front face transparent electrode 15, front face liquid crystal molecular orientation layer 16, liquid crystal layer 17, sealing member 18, back face liquid crystal molecular orientation layer 19, back face transparent electrode 20, back face glass substrate 21, back face polarizer 22 and reflecting plate 23, when viewed from the viewer 12 side. Here, by applying such a voltage at which the opening angle ϕ of the optical fiber aggregate 14 and the maximum visual angle θ producing contrast in non-selected region nearly coincide, it becomes possible to pass all of the rays of the visual range where contrast is obtainable through the optical fibers in the optical fiber aggregate 14 and let the same arrive at the viewer, thus the high contrast may be obtained.
