Abstract: According to one embodiment, a liquid crystal display device includes an array substrate, a counter substrate, a liquid crystal layer, and a sealing material. The array substrate includes signal lines, scanning lines, pixel electrodes, and elongated protrusions. The counter substrate includes counter protuberances and a planarization film. Each of the elongated protrusions of the array substrate extends in such a way as to cover a corresponding one of the signal lines and in a rib-like manner along the corresponding signal line. Each of the counter protuberances of the counter substrate is formed integrally with the planarization film and is formed to extend along a direction intersecting a corresponding one of the elongated protrusions. An outer edge of the planarization film is located nearer to a central portion of the liquid crystal display device than an inner edge of the sealing material.

Abstract: A first substrate includes a first switching element arranged in a first color pixel and a second switching element arranged in a second color pixel of which color is different from the color of the first color pixel in an active area. A driving unit superimposes DC bias voltages on voltages corresponding to gradations to be displayed in the first color pixel and the second color pixel, and to supply the superimposed voltages to the first pixel electrode and the second pixel electrode, respectively. A first halftone gradation voltage obtained by superimposing a first DC bias voltage on a voltage corresponding to a halftone gradation is supplied to the first pixel electrode. A second halftone gradation voltage obtained by superimposing a second DC bias voltage different from the first DC bias voltage on a voltage corresponding to the halftone gradation is supplied to the second pixel electrode.
