The invention relates to a liquid crystal display device comprising a black mask (17) formed on one of two substrates (1, 1') at least one of which is transparent, a group of electrodes (2, 11) formed on at least one of the substrates (1, 1'), a liquid crystal layer comprising a liquid crystal composition (21) having a dielectric anisotropy and held between the substrates (1, 1'), an orientation control film (20, 20') formed between the liquid crystal layer and one or both of the substrates (1, 1') for orienting the liquid crystal molecules of the liquid crystal composition in a predetermined direction, polarizing means (13, 13') laminated on at least one of the two substrates (1, 1') and driving means for applying a drive voltage to the group of electrodes (2, 11) wherein the group of electrodes (2, 11) has such a structure that an electric field having a component predominantly in parallel with the interface between the orientation control film (20, 20') and the liquid crystal layer is generated, the liquid crystal composition has a resistivity of not smaller than 10<N> OMEGA .cm, and the black mask (17) has a resistivity of not smaller than 10<M> OMEGA .cm, wherein N and M are integers satisfying the conditions N > 9 and M > 6. Thereby, the light-shielding ability of the black mask (17) is practically satisfactory, a disturbance of the electric field pattern is eliminated, and color displays of high quality without color nonuniformity can be achieved. <IMAGE> |
