ABSTRACT:
A liquid crystal display (LCD) capable of preventing light leakage includes first and second gate lines which extend in a horizontal direction, a data line which is insulated from the first and second gate lines and crosses the first and second gate lines, first and second thin film transistors (TFTs) which are respectively connected to the first and second gate lines and are connected to the data line, and a pixel electrode which extends in zigzag fashion at an inclination to the first and second gate lines and is divided into a first area and a second area in a direction in which the pixel electrode extends. The pixel electrode includes a first sub-pixel electrode which is connected to the first TFT and has the first area and upper and lower portions of the second area, and a second sub-pixel electrode which is connected to the second TFT, has a middle portion of the second area, and has a lateral side adjoining a first portion of the first sub-pixel electrode, an upper side adjoining a lower side of an upper second portion of the first sub-pixel electrode, and a lower side adjoining an upper side of a lower second portion of the first sub-pixel electrode, the first and second areas being connected by a plurality of connection electrodes, and at least one of the connection electrodes overlapping the second gate line.
