Abstract
Disclosed is a liquid crystal display having high aperture ratio and high transmittance comprising: first and second transparent insulating substrates opposed with intervening a liquid crystal layer; gate bus lines and data bus lines arranged cross to each other on the first transparent insulating substrate so as to define pixel regions; a counter electrode disposed within each pixel region, made of a transparent conductive material, and having a plurality of first branches disposed parallel with the data bus lines with equal distance and a bar connecting one ends of the first branches; a common signal line applying a common signal to the counter electrode disposed within each pixel region, contacted with the bar of the counter electrode, disposed parallel with the gate bus line, and having a pair of second branches branched toward the data bus line and disposed between the data bus line and the first branches of both edges of the counter electrode; a pixel electrode disposed within each pixel region to generate a fringe field together with the counter electrode, made of a transparent conductive material, and having a plurality of third branches disposed parallel to the data bus li…
