Classification: CPC G | IPC G

Claim 8:
9. A display device comprising:
a display panel including a pixel connected to a scan line and a data line;
a scan driving circuit configured to drive the scan line;
a data driving circuit configured to receive an image signal and to output a data signal corresponding to the image signal to the data line;
a driving controller configured to control the scan driving circuit and the data driving circuit and to output the image signal; and
a power manager configured to provide a driving voltage to the display panel and the data driving circuit,
wherein the data driving circuit comprises:
a noise filter configured to receive a driving voltage and remove a noise from the driving voltage to output a filtered driving voltage;
a first voltage generator configured to output a first voltage, a second voltage, and a third voltage;
a second voltage generator configured to generate a first reference voltage based on the filtered driving voltage, the first voltage, and the second voltage;
a third voltage generator configured to generate a second reference voltage based on the filtered driving voltage, the second voltage, and the third voltage; and
an output circuit configured to output the data signal of a voltage level corresponding to the image signal based on the first reference voltage and the second reference voltage.
