A display device includes a display including a plurality of pixels having a plurality of light-emitting elements, a pixel selector configured to select a pixel from among a plurality of pixels, a positional information generator configured to generate the positional information representing the position of the selected pixel, and a light emission processor configured to superpose the positional information on the light emitted by the selected pixel. A position detecting device is used to detect and output the positional information superposed on the light of the selected pixel on the display device, thus making it easy to accurately detect the position of the pixel subjected to calibration in luminance.

Display device equipped with position detecting device for detecting positions of pixels subjected to luminance calibration

A light source includes an invisible light emitter that emits an invisible light beam and a visible light emitter that emits a visible light beam. A light source controller causes the light source to emit at least one light beam from among the invisible light beam and the visible light beam. A propagation controller causes an emission light beam emitted from the light source to propagate along a predetermined plane.
