Disclosed is a double-sided display device which comprises a display panel that has a plurality of pixels arranged in a matrix form and displays an image; a blank means that blanks out some pixels on one surface of the display panel with an arbitrary pattern to prevent an image which the pixels display from being shown and blanks out other pixels, except for the pixels blanked out with the arbitrary pattern, on the other surface of the display panel; and a conversion unit that makes a conversion such that the left and right sides of the image displayed through the pixels blanked out by the blank means and the image displayed through the pixels which are not blanked out are reversed with respect to the one surface of the display panel, and provides the converted images to the display panel.
