Disclosed is a liquid crystal display mainly including a plurality of pixel electrodes, scanning lines, signal lines and auxiliary capacitor lines on a thin film transistor (TFT) substrate, and a light-shielding matrix on a color filter (CF). Each signal line is bent between two adjacent scanning lines, so as to form a first portion, a second portion and two connection portions connecting the first and second portions. The first and the second portions are respectively covered with opposite side portions of two adjacent pixel electrodes. Each auxiliary capacitor line has a main body parallel to the scanning line and an extension portion extending outwardly from the main body. The extension portion of each auxiliary capacitor line is located between the two connection portions of the data line.
