Abstract:
1. A display device, comprising: a plurality of pixel formation portions for forming an image to be displayed; a plurality of video signal lines for transmitting a plurality of video signals representing the image to the plurality of pixel formation portions; a video signal line driving circuit that has a plurality of output terminals respectively corresponding to a plurality of video signal line groups made by grouping the plurality of video signal lines into groups of two or more video signal lines, for outputting, by time division, from each of the output terminals the video signals to be transmitted by the video signal line group corresponding to that output terminal; a plurality of scanning signal lines intersecting with the plurality of video signal lines; and a scanning signal line driving circuit for respectively applying to the plurality of scanning signal lines a plurality of scanning signals for selectively driving the plurality of scanning signal lines; a connection switching circuit for connecting each of the output terminals of the video signal line driving circuit to one of the video signal lines in the corresponding video signal line group, and switching the video signal line to which each of the output terminals is connected within the corresponding video signal line group in accordance with said time division; wherein the plurality of pixel formation portions are arranged in a matrix, in correspondence to the intersections between the plurality of video signal lines and the plurality of scanning signal lines; wherein each of the pixel formation portions comprises: wherein the connection switching circuit connects, by time division, each of the output terminals of the video signal line driving circuit to the video signal lines within the corresponding video signal line group from the time when one scanning signal line is selected by the scanning signal line driving circuit and until another scanning signal line is selected; wherein each of the plurality of video signal line groups is made of a plurality of video signal lines that are spaced apart by an odd number of video signal lines so that first and second video signal lines of a given group are spaced apart from one another by at least one video signal line of a different group; wherein the video signal line driving circuit outputs the plurality of the video signals such that voltages of different polarities are applied to neighboring video signal lines of the plurality of video signal lines; and wherein the connection switching circuit changes a switching order of the video signal lines to be connected to each of the output terminals of the video signal line driving circuit in accordance with a switching of the scanning signal line selected by the scanning signal line driving circuit.
