Abstract: A display device is provided. The display device includes a display panel, a sensor, and a polarizer. A polarization direction of light emitted from the display device to the sensor includes, at least, a first polarization direction. The first polarization direction is parallel to an absorption axis of the polarizer. By absorbing stray light parallel to the absorption axis of the polarizer, a luminous flux of the stray light emitted to the sensor is reduced, and a light receiving quality of the sensor is improved.
