Abstract: A liquid crystal display device includes a pixel electrode having a stem electrode in a first direction and a plurality of branch electrode extending from the stem electrode. An angle between the stem electrode and each of the branch electrode increases as the branch electrodes approach a center of the stem electrode and the angle decreases as the branch electrodes approach an end of the stem electrode.
