Display device

An active-matrix display device for providing gradation display of a video to be displayed, the active-matrix display device comprising:

• a display panel including a plurality of scanning signal lines, a plurality of video signal lines crossing the scanning signal lines, and a plurality of display elements disposed in a matrix corresponding to respective intersections of the scanning signal lines and the video signal lines;
• a scanning signal line driver circuit configured to selectively activate the scanning signal lines;
• a gradation reference voltage generation circuit configured to output gradation reference voltages;
• and
• a video signal line driver circuit including a gradation voltage generation portion configured to generate gradation voltages based on the gradation reference voltages outputted by the gradation reference voltage generation circuit and a selector portion configured to select one of the gradation voltages based on an externally provided video signal, thereby generating an analog video signal, and apply the analog video signal to the video signal line,
• wherein the gradation voltage generation portion includes first voltage lines extending from output terminals for outputting the generated gradation voltages, the first voltage lines being grounded outside the video signal line driver circuit via first capacitors,
• wherein the gradation voltage generation portion includes a voltage ladder including a plurality of resistive elements connected in series, and the gradation voltage is a voltage obtained by subjecting a voltage derived from the gradation reference voltage generation circuit to resistive division by the resistive elements, and
• wherein the gradation reference voltage generation circuit provides the gradation reference voltages to terminals of resistive elements situated at opposite ends of the resistive elements connected in series in the voltage ladder and also to predetermined connection nodes between all the connection nodes of the resistive elements in series in the voltage ladder.
