Abstract
A display device includes a polarizing layer having a polarizing function for reflecting or absorbing light polarized in a stretching direction of a pigment, a first display panel in which the polarizing function is disabled in a first region, a second display panel in which the polarizing function is disabled in a second region, and a light source that emits an illumination light having a polarization direction along the stretching direction or a direction perpendicular to the stretching direction. The first display panel and the second display panel are stacked together to form a display unit. Only the first region is displayed on the display unit by emitting illumination light having a polarization direction along the stretching direction of the first display panel. Only the second region is displayed on the display unit by emitting illumination light having a polarization direction along the stretching direction of the second display panel.
