摘要:
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.

A first phase plate and a third phase plate, which constitute a polarizer structure, cooperate to impart a phase difference of a ¼ wavelength to linearly polarized light that emerges from a first polarizer plate. A second phase plate and a fourth phase plate cooperate to impart a phase difference of a ¼ wavelength to linearly polarized light that emerges from a second polarizer plate. Slow axes in planes of the first phase plate and the second phase plate are substantially parallel. A crossed-axes angle between slow axes in planes of the first phase plate and the third phase plate is 60°, a crossed-axes angle between slow axes in planes of the second phase plate and the fourth phase plate is 60°, and a crossed-axes angle between slow axes in planes of the third phase plate and fourth phase plate is 60°.

A liquid crystal display device includes an array substrate having a pixel electrode formed of a conductor, a counter substrate having a counter electrode facing the pixel electrode, and a liquid crystal layer held between the substrates and containing liquid crystal molecules set in a vertical alignment with respect to the substrates. The pixel electrode had a void space located in the conductor to provide minute domains between which different directors of the liquid crystal molecules are obtained when a potential difference is applied between the array and counter electrodes, and a bridge-wiring member interconnecting adjacent parts of the conductor in the void space, and the bride-wiring member is configured to make an electric field created in a part of the pixel area located on the bridge-wiring member weaker than that created in the minutes domains according to the potential difference.
