A liquid crystal display device includes a plurality of pixels disposed on an insulation substrate in a horizontal direction, and including a thin film transistor region and a display area; and a reference voltage line extended along a center of the display area in a direction perpendicular to the horizontal direction. The display area includes a plurality of domains disposed in two rows, a domain in one of the two rows includes a high-gray subpixel area including a high-gray pixel electrode, and a domain in the other of the two rows includes a low-gray subpixel area including a low-gray pixel electrode. The high-gray pixel electrode and the low-gray pixel electrode each include a plurality of unit pixel electrodes, and each unit pixel electrode includes a center electrode having a planar structure and a plurality of minute branches that extend from a side of the center electrode.
