A liquid crystal includes first and second substrates, the first substrate including intersecting data lines and scan lines. A liquid crystal layer is sandwiched therebetween. Also, a plurality of sub-pixels districted by data lines and gate lines, and arranged along the long-axis and the short-axis directions in a matrix. A pixel electrode in the sub-pixels includes a central portion. A common electrode including linear electrodes arranged along the data lines and disposed with gaps therebetween. Sub-pixels are bent at the center portion, such that the linear electrodes or the gaps in both sides of the sub-pixels are inclined in opposite directions with respect to the long-axis direction. At least one of the linear electrodes or at least one of the gaps has a bent portion at the central portion of the respective pixel electrode.
