Abstract: Provided are a display device and method of driving the same. A display device includes: a display panel including: intersecting data lines and gate lines, and pixels in a matrix, a timing controller allowing the pixels to be driven at a lower refresh rate in low-speed driving mode than in normal driving mode, and controlling a horizontal blank time to be longer in the low-speed driving mode than the normal driving mode, the horizontal blank time being a period of time during which no data voltage exists, between an nth data voltage and an (n+1)th data voltage consecutively supplied through the data lines, “n” being a positive integer, and a display panel driving circuit writing one frame of image data to the pixels during one frame period in the normal driving mode, and in a distributed manner during a second to fourth frame period in the low-speed driving mode.
