1. A display device comprising:
a display panel in which a plurality of pixels are disposed;
a data driver supplying a data voltage to the plurality of pixels; and
a demultiplexer unit is disposed between the data driver and a display area of the display panel,
wherein each of the plurality of pixels includes:
a light-emitting element; and
a pixel circuit configured to control the light-emitting element,
wherein the pixel circuit includes:
a capacitor connected to and disposed between a first node and a second node; and
a driving transistor including a gate electrode connected to the second node, a first electrode receiving a driving voltage, and a second electrode connected to a third node,
wherein the pixel circuit is configured such that a reference voltage is supplied to the first node and the second node during a portion of an operation period of the pixel circuit,
wherein the demultiplexer unit distribute a data voltage output from one channel of the data driver in a time division manner and supplies to the plurality of pixels.
