A liquid crystal display device comprising a liquid crystal layer including liquid crystal molecules provided between a first substrate and a second substrate; pixels forming a display area; electrodes for applying a voltage across the liquid crystal layer within each of the pixels; a plurality of domain regulating structures for dividing orientations of the liquid crystal molecules and forming multiple domains within each of the pixels, when a predetermined voltage is applied across the liquid crystal layer within each of the pixels. The device also includes a structure which is formed in an outer area located next to the display area, but that does not overlap the display area, and is substantially the same as at least one of the plurality of domain regulating structures.

Liquid crystal display device

A liquid crystal display device includes a panel having pixel electrodes arranged at intersections of a plurality of signal lines via switching elements for transmitting display data and a plurality of scanning lines for transmitting control signals, and a control circuit for controlling the panel. The liquid crystal panel is divided into first pixel regions and second pixel regions adjacent to the first pixel regions. The control circuit carries out impulse driving in which the control signals transmitted to each of the scanning lines are activated two times in one frame period for displaying an image. The control circuit writes the display data in either one of the pixel regions and writes reset data in the other pixel regions when the control signals are activated once of the two times. By writing the reset data in the pixel regions, the display data written in an immediately preceding frame are reset. In consecutive frames, the display data written in the pixel regions are always reset in one frame period. Therefore, blurring in a moving image can be alleviated. Since writing the display data and the reset data is carried out separately in the first pixel regions and in the second pixel regions, flicker is prevented from occurring in a display screen.

Additionally, each of the first and second linear portions and the alignment control structures of the second substrate are arranged in parallel.
