Abstract: A display device according to an example includes a first power sharing line disposed to be parallel with a first direction, first and second pixels disposed along a second direction crossing the first direction with the first power sharing line interposed therebetween, and a second power sharing line disposed to be parallel with the first power sharing line with any one of the first and second pixels interposed therebetween.

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.
