Abstract
Between the substrates with electrodes arranged to face each other, there is held a neamtic liquid crystal layer having a molecular arrangement capable of obtaining two or more directions of the tilt direction when an electric field is applied. The electrode structure is formed by a region having the conductive sections the width of which is 50 .mu.m or less in the widest part and the non-conductive sections the width of which is 50 .mu.m or less in the widest part per pixel. Between the substrates arranged to face each other, the conductive sections and non-conductive sections are opposed to each other at least per pixel in a part of the region in the pixel, and given the width of the narrowest part of the non-conductive sections as S, and the distance between the electrodes of the substrates arranged to face each other as D, the relationship of D.gtoreq.S/2 is satisfied. With this structure, it is possible to obtain a liquid crystal display device having a high light scattering characteristic at a low driving voltage, and also, with a high gradation having a bright contrast ratio. There is no inverted display even when a gradation display is executed, and a liquid crystal display device can be obtained with an extremely wide viewing angle. These characteristics can be sufficiently maintained in practice in a state of a voltage being applied.
