Abstract: A display device is described that has reduced resistance in one or more of the gate, common, data electrical lines that control the operation of the pixels of the display device. Reduced resistance is achieved by forming additional metal and/or metal-alloy layers on the gate, common, and/or data lines in such a manner so that the cross-sectional area of those lines is increased. As a consequence, each such line is formed so as to be thicker than could otherwise be achieving without causing defects in the rubbing process of an alignment layer. Additionally, no widening of these lines is needed, thus preserving the aspect ratio of the device. The gate insulating and semiconducting layers that in part make up the thin film transistors that help control the operation of the pixels of the device may also be designed to take into account the increased thickness of the lines.

Abstract: A pixel array of a liquid crystal display is discussed. The pixel array can include a first pixel including a first pixel electrode charged to a first data voltage, an upper common electrode which is positioned opposite the first pixel electrode and forms an electric field, a lower common electrode applying a common voltage to the upper common electrode, and a first storage capacitor for holding the first data voltage during a predetermined period, and a second pixel including a second pixel electrode charged to a second data voltage, the upper common electrode, the lower common electrode, and a second storage capacitor for holding the second data voltage during a predetermined period. The first and second storage capacitors are located in a storage area between the first and second pixels, which are positioned adjacent to each other in a horizontal direction.
