A touch panel includes a first substrate, a cover that is formed from glass and that is overlaid on the first substrate, and a first adhesive layer that adheres the first substrate to the cover. The first substrate includes a base that is formed from glass and that includes a detection region and a surrounding region surrounding the detection region, a plurality of first electrodes that is disposed in the detection region of a first main surface of the base, and that extends in a first direction, and an organic thin film that is formed on the first main surface of the base, and that covers the plurality of first electrodes. The first adhesive layer directly adheres the organic thin film to the cover, and the surrounding region of the first main surface of the base to the cover.

Touch panel and display device

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.

Display device

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.
