Reference voltage generating section, display device including same, and method for driving same

The invention provides a reference voltage generating section, a display device including the same, and a driving method of the display device. The display device may include: a display panel including a plurality of pixels displaying an image based on a driving voltage; the reference voltage generation unit converts a sensing drive voltage generated by measuring the drive voltage into a sensing drive current, converts a preset reference drive voltage into a reference drive current, and compares the sensing drive current with the reference drive current. Generating a first reference voltage and a second reference voltage based on a difference between the sensing driving current and the reference driving current; a gamma voltage generation unit that generates a plurality of gamma voltages by dividing the first reference voltage and the second reference voltage; and a data driving section that converts the image data into a data voltage based on the gamma voltage, and supplies the data voltage to each pixel. 提供
