1. A display device comprising:
a first liquid crystal panel;
a second liquid crystal panel disposed on a back face side of the first liquid crystal panel;
a position compensation unit configured to compensate for a display position of an image on the second liquid crystal panel based on position compensation information indicating a relative positional relationship between the first liquid crystal panel and the second liquid crystal panel;
an area expansion unit configured to expand a first displayable area of the image before the display position is compensated for, or a second displayable area of the image after the display position is compensated for, by the position compensation unit; and
a cutting unit configured to cut an area not displayed on the second liquid crystal panel from the image expanded by the area expansion unit,
wherein the area expansion unit expands the first displayable area of the image based on a result of performing a filtering on each of a plurality of pixels composing a perimeter of the image as a pixel of interest.
