1. A display device including a display area in a non-rectangular shape, wherein a plurality of rectangular-shaped pixels are arranged in the display area and a non-display area, each pixel including a plurality of subpixels that correspond to a plurality of colors, respectively, the display device comprising:

  • a brightness value adjustment circuit that, during image display, adjusts a brightness value of a boundary pixel that extends across both the display area and the non-display area such that the brightness value of the boundary pixel is set to a value between a first brightness value of a first pixel whose subpixels are all located in the non-display area and a second brightness value of a second pixel that is adjacent to the boundary pixel and whose subpixels are all located in the display area,wherein the brightness value adjustment circuit adjusts the brightness value of the boundary pixel m such that, as a portion of the boundary pixel included in the non-display area is larger in area, all of the subpixels of the boundary pixel have briqhtness values closer to the briqhtness value of the pixel in the non-display area, andwherein the brightness value adjustment circuit further adjusts the brightness value of the boundary pixel m such that, when the brightness value of the pixel whose subpixels are all located in the non-display area and the brightness value of the pixel that is adjacent to the boundary pixel and whose subpixels are all located in the display area are equal to each other, the brightness value of the boundary pixel is equal to the brightness value of the pixel whose subpixels are all located in the non-display area.
