This display device is provided with a display unit (2) which displays an image, a recording unit (3) which records three-dimensional data of an object displayed on the display unit (2), and a calculation unit (4) which, on the basis of a first illumination direction, a first light intensity, and a second light intensity, calculates the shape of a shadow of the object using the three dimensional data and the first illumination direction, also calculates the intensity of the shadow using the first light intensity, and also calculates a correction coefficient for the calculated intensity of the shadow using the second light intensity, wherein: the first illumination direction is the direction from which the light of the highest intensity received by the display unit (2) illuminates the display unit (2); the first light intensity is the intensity of the light illuminating the display unit (2) from the first illumination direction; and the second light intensity is the intensity of light illuminating the display unit (2) from a direction different from the first illumination direction, and is lower than the first light intensity. The display unit (2) displays an image in which the object casts a shadow created on the basis of the results of the calculation by the calculation unit (4).
