Abstract
A display device includes a plurality of data lines, a transmission gate element connected to the data lines, wherein the transmission gate supplies precharge voltages and data voltages to the data lines in response to transmission gate signals, and a plurality of pixels connected to the data lines. Each of the pixels includes: a light emitting element; a capacitor; a driving transistor having a control terminal connected to the capacitor, an input terminal, and an output terminal, wherein the driving transistor supplies a driving current to the light emitting element; a first switch, wherein the first switch diode-connects the driving transistor in response to a gate signal and connects one of the data lines to the capacitor; and a second switch, wherein the second switch supplies a reference voltage to the capacitor in response to the gate signal and connects the driving transistor to the light emitting element, wherein the precharge voltage, the data voltage, and the reference voltage are applied to the capacitor, and wherein the capacitor stores a charging voltage based on the applied data voltage and a threshold voltage of the driving transistor.
