Abstract
The invention discloses a display panel and a display device. The display panel comprises a display liquid crystal box, a first polarizer, a dimming liquid crystal box and a second polarizer, wherein the dimming liquid crystal box comprises a first substrate, a second substrate, a dimming liquid crystal layer and a first phase compensation film set, and the dimming liquid crystal layer comprises a polymer network and a plurality of dimming liquid crystal molecules distributed in the polymer network. According to the invention, the first substrate and the second substrate are both replaced by transparent flexible substrates from glass substrates in the prior art, the first phase compensation film group is additionally arranged between the display liquid crystal box and the second polarizer, and the first phase compensation film set at least comprises a first C-shaped compensation film set, and is used for compensating phase difference caused by phase delay when polarized light passes through a transparent flexible substrate, so that the thickness and the weight of the display panel can be reduced while the peep-proof effect is not affected.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Adding a dimming liquid crystal cell to control the viewing angle on one side of the conventional display liquid crystal cell can make the display panel freely switch between the private mode with a narrow viewing angle and the sharing mode with a wide viewing angle. Among them, the dimming liquid crystal cell includes upper and lower substrates, a polymer network arranged between the upper and lower substrates, and dimming liquid crystal molecules distributed in the polymer network. Since the upper and lower substrates are glass substrates, the overall thickness and weight of the anti-peeping display Both increase, which is contrary to the current trend of thinner and lighter displays. Contents of the invention [0003] Embodiments of the present invention provide a display panel and a display device...
