Abstract: A display device includes a first liquid crystal display, a decorative member, an illuminator, and a controller. The decorative member is disposed on a display surface side of the first liquid crystal display, and includes a first display region in which a display of the first liquid crystal display is transparently displayed and a first non-display region adjacent to the first display region. The illuminator illuminates the first non-display region from the back surface. The controller controls, in accordance with a luminance of a first black display region, of the first display region, that corresponds to a black display portion the first liquid crystal display, an amount of illumination light emitted from the illuminator toward the first non-display region.

Abstract: A display device includes a liquid crystal display including a first liquid crystal display panel that displays a character or an image; a decorative member; and a controller that controls the display of the liquid crystal display. The decorative member is disposed on a display surface side of the liquid crystal display, and includes a display region in which the display of the liquid crystal display is transparently displayed, and a non-display region adjacent to the display region. The controller controls a luminance through the decorative member of a black display of the liquid crystal display to a luminance invisible to a user, and controls the luminance through the decorative member of a low-gradation region, except for the black display, of the liquid crystal display to a luminance visible to the user.
