    • Disclosed is a liquid crystal display capable of high quality image and bright display. Gate signal lines are curved at near switching elements of the liquid crystal display. A pixel area is defined by the gate signal lines and their intersecting data signal lines. Pixel electrodes and common electrodes are disposed along a longitudinal direction of a pixel. A pixel signal and a common signal line is connected to the pixel electrode and the common electrode respectively. A storage capacitor may be formed in the middle of a longitudinal direction of the pixel, or where generally a texture may arise during display. One half of the pixel may be symmetrical with the other half with respect to the storage capacitor. A common signal line may be parallel with the data signal line and be disposed nearer to the data signal line than a pixel signal line. The pixel may be disposed symmetrically with respect to the data signal line therebetween. The pixel shape may also be repeated in the direction of the gate signal line.
