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: According to an aspect of the present disclosure, a display device includes a display panel which includes sub pixels configured by an upper sub pixel and a lower sub pixel which share a data line and are adjacent to each other; and a data driver which converts only image data corresponding to any one of even-numbered grayscale levels and odd-numbered grayscale levels among 10-bit image data into a data voltage to supply the converted data voltage to the sub pixel, in which when the data driver converts only the even-numbered grayscale levels of image data into the data voltage and the sub pixel displays an X (X is an odd number) grayscale level, the data driver supplies an X−grayscale level of data voltage to the upper sub pixel and supplies an X+1 grayscale level of data voltage to the lower sub pixel.
