    Abstract: A display device includes a display panel and an infrared sensing module. The display panel includes an active region in which a pixel that emits light based on a data signal is disposed. The infrared sensing module transmits a first infrared light that passes through the active region and receives a second infrared light that passes through the active region to recognize an object. The wavelength of the first infrared light may have a wavelength greater than a predetermined value so that a luminance of light emitted by the pixel is not affected by operation of the infrared sensing module.
