    Abstract: A display device is disclosed that includes a display panel on which one or more sub-pixels including a light emitting device and a driving transistor for driving the light emitting device are disposed in a display area, and whose shape is changed during a transforming period, a timing controller for receiving image data and a command signal defining the transforming period, and converting the image data to output converted image data, and a data driving circuit for receiving the converted image data and outputting a data voltage, wherein, in the transforming period, at least one sub-pixel emits light based on the image data input to the timing controller, and emits light with a luminance lower than a luminance corresponding to a grayscale of the image data. Accordingly, there may be provided a display device capable of changing a shape during an image display period.
