Abstract
The present disclosure provides a display device. The display device includes a display panel, an infrared camera, an infrared light source, a first imaging polarizing plate, and a second imaging polarizing plate. The infrared camera is arranged on a rear surface side that is an opposite side to a display surface of the display panel. The first imaging polarizing plate is arranged at a first position matching a main surface side of the display panel and has a first polarization characteristic for infrared light. The second imaging polarizing plate is arranged at a second position on an output side of the infrared light source and has a second polarization characteristic that is different from the first polarization characteristic for infrared light.
