1. A display device comprising:
a lighting device including light sources and a light exit area from which light emitted by the light sources exits, the light exit area including light exit sections that are defined corresponding to the light sources;
a display panel mounted on the lighting device and including a display area and a non-display area, the display area disposed opposite the light exit area and displaying an image and the non-display area disposed around the display area, the display panel further including pixels arranged in a matrix in the display area, the display area including display sections that are defined to be respectively disposed opposite the light exit sections;
a memory storing default pixel matrix data including a plurality of position data of default pixel matrix units including the pixels that are linked to the display sections with respect to design,
the memory further storing non-opposite pixel data and deviation data when a position error is caused between the light exit area and the display area,
the non-opposite pixel data including position data of one or more of the pixels that are not disposed opposite the light exit area when the position error is caused,
the deviation data including data representing a deviation direction and a deviation amount that are related to a deviation between positions of the default pixel matrix units that are included in the default pixel matrix data and positions of opposite pixel matrix units that are disposed opposite corresponding light exit sections when the position error is caused; and
a correction circuit connected to the memory and configured to
determine whether the memory stores the non-opposite pixel data, and
if determining that the memory stores the non-opposite pixel data, respectively link the opposite pixel matrix units of the pixels that are off from the default pixel matrix units included in the default pixel matrix data by the deviation amount in the deviation direction represented by the deviation data to corresponding display sections, and create new pixel matrix data related to the opposite pixel matrix units in the corresponding display sections and store the new pixel matrix data in the memory.
