Abstract
An in-plane switching type liquid crystal display device includes (a) a first substrate on which a plurality of gate lines and a plurality of data lines are formed such that the gate lines are substantially perpendicular to the data lines, and on which at least one pixel electrode and at least one common electrode are alternately formed in each of pixels defined by the gate and data lines, (b) a second substrate facing the first substrate, and (c) a liquid crystal layer sandwiched between the first and second substrates, wherein when a voltage is applied across the pixel electrode and the common electrode, liquid crystal existing on extensions of the data lines are caused to rotate in a plane substantially in parallel with the first substrate. Both the pixel electrode and the common electrode have at least one bending point at which the pixel electrode and the common electrode bend, and are designed to bend such that both an intensity and a direction of a field generated by the voltage successively vary.
