Claim 9:
10. A display device comprising:
a display panel including a display region and a non-display region; and
a display panel driving circuit which drives the display panel,
wherein the display panel driving circuit divides a boundary pixel, through which a smoothing reference line corresponding to a boundary between the display region and the non-display region passes, among pixels included in the display region into a first pixel region in the display region and a second pixel region in the non-display region based on the smoothing reference line, and performs a luminance dimming on the boundary pixel, wherein each of the pixels includes sub-pixels, and the luminance dimming is performed on all of the sub-pixels of the boundary pixel based on a dimming luminance determined based on a smoothing rate corresponding to a ratio of an area of a first pixel region to a total area of the boundary pixel including the sub-pixels, and
wherein the display panel driving circuit does not perform the luminance dimming on a non-boundary pixel, through which the smoothing reference line does not pass, among the pixels.
