Abstract
Disclosed is a display device including a display panel, a reflective polarizing layer, a liquid crystal dimmer cell, and a first polarizing plate which are sequentially stacked, wherein a reflection surface of the reflective polarizing layer faces the liquid crystal dimmer cell, and a direction of a transmission axis of the reflective polarizing layer is same as a direction of a transmission axis of the first polarizing plate, so that not only a peep-proof function of the display device can be realized, but also ambient light with a large viewing angle can be reflected, which can further reduce the visibility of the display screen under the large viewing angle without affecting the display at the front viewing angle.
