Abstract:
1. A stereoscopic display device having a function of displaying an image in a stereoscopic manner in a display screen having a horizontal direction and a vertical direction, the stereoscopic display device comprising: a plurality of scanning signal lines that extend along the vertical direction of the display screen; a plurality of video signal lines that extend along the horizontal direction of the display screen, and are classified, according to an arrangement order, into groups each including a first number of video signal lines; a pixel array that includes a plurality of pixel circuits arranged corresponding to intersections between the scanning signal lines and the video signal lines; a scanning signal line drive circuit configured to select the scanning signal lines; a video signal line drive circuit configured to divide one horizontal period into a second number of periods, the second number being equal to the first number, and output, to each group of the video signal lines, a voltage to be applied to the video signal lines in the group in a time-division manner within one horizontal period; and a video signal line selection circuit including a plurality of analog switches positioned away from the pixel array, each corresponding to the video signal line, and configured to, by controlling the switches, select one of the video signal lines, based on switch control signals, in each group, and supply the voltage outputted from the video signal line drive circuit to the selected video signal line, wherein the pixel array is configured such that columns each having pixel circuits for left eye arranged along the vertical direction of the display screen and columns each having pixel circuits for right eye arranged along the vertical direction of the display screen are alternately arranged along the horizontal direction of the display screen, and an order of writing to the pixel circuits corresponding to the same scanning signal line within one horizontal period, the order being determined by controlling the switches, is changed every two scanning lines.
