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.

Abstract: A display panel and a display device are provided. The display panel includes a first substrate, a second substrate, and a liquid crystal layer between the first substrate and the second substrate. The liquid crystal layer comprises a plurality of liquid crystal molecules. When the display panel is in a first display mode, the plurality of liquid crystal molecules rotate in a slanted plane parallel to a first direction and a second direction. The first direction is slanted with respect to a thickness direction of the display panel, and the second direction is perpendicular to the thickness direction of the display panel and the first direction.

Abstract: A display panel and a display device are disclosed. The display panel includes a display liquid crystal cell, a first polarizer, a switchable liquid crystal cell, and a second polarizer. A first substrate and a second substrate of the switchable liquid crystal cell are formed of transparent flexible substrates which are substituted for glass substrates, and a first phase compensation film group including at least a first C-type compensation film group is provided, which is used to compensate the phase difference caused by the phase retardation when the polarized light passes through the transparent flexible substrates, thereby reducing the thickness and weight of the display panel.
