Abstract: A display device and a driving method therefor are provided in the present disclosure. The display device of the present disclosure comprises: a display panel for displaying an image; a backlight for providing light to the display panel; a liquid crystal panel which is arranged between the display panel and the backlight and which includes a first transparent electrode sheet, a second transparent electrode sheet, and a liquid crystal layer formed between the first and second transparent electrode sheets and arranged according to the difference in voltages applied to the first and second transparent electrode sheets; and a control unit for applying a driving voltage to a block, which corresponds to a region of the display panel on which the image is displayed, from among a plurality of blocks of the first transparent electrode sheet in order to apply a voltage to a specific point inside the block, wherein the voltage applied to the specific point is determined on the basis of the distance between a point of the first transparent electrode sheet at which the driving voltage is applied and the specific point.
