Abstract

PURPOSE: To make the response time of all layers equal and obtain the display free from any interference color in the background of the display and of less extraneous feel and high contrast ratio by constituting the respective liquid crystal layers of the multilayer type twisted nematic liquid crystal display device by the same material and making the layer thicknesses equal.
CONSTITUTION: With an example being taken of a two layer structure liquid crystal display device, electrodes 2aW2d are formed on the inside surfaces of the cells constituted by three glass substrates 1aW1c. Twisted nematic liquid crystal molecule layers 4 are sealed by way of liquid molecule orientation treatment layer 3 between the respective substrates 1aW1c, by using sealing materials 5. Polarizing filters 6 are provided on the front and back sides respectively of the device. For the liquid crystal layers 4, the respective layer thickness d1, d2 are constituted by 7μ± 1μ and d1/d2 are so formed as to be within the range from 0.75W1.35. Since the elliptically polarized components produced in the 1st layer are corrected, in this way, in the 2nd layer, the high contrast ratio is obtainable.
