ABSTRACT:
A liquid crystal display (LCD) capable of preventing texture, light leakage, and/or formation of an instantaneous afterimage while improving an aperture ratio is presented. The LCD includes a first insulating substrate, a gate line formed on the first insulating substrate, a data line insulated from the gate line and extending substantially perpendicularly to the gate line wherein the gate line and the data line define a pixel, and a thin film transistor (TFT) connected to the gate line and the data line. A first sub-pixel electrode is connected to the TFT, and a second sub-pixel electrode is capacitively coupled to the first sub-pixel electrode through a coupling electrode, the second sub-pixel electrode being separated from the first sub-pixel electrode by a gap. The LCD also includes a second insulating substrate, a common electrode formed on the second insulating substrate and including a domain divider, and a liquid crystal layer interposed between the first insulating substrate and the second insulating substrate. A coupling electrode connecting portion connects the TFT to the coupling electrode and intersects the gap at a region along an edge of the pixel.
