Abstract
A display panel and a display device are provided. The display panel includes a substrate; a light-emitting layer disposed on the substrate; a plurality of separating plates disposed on the light-emitting layer; an encapsulation layer disposed on the plurality of separating plate; and a viewing angle switching assembly disposed in the accommodating cavity. The substrate, the plurality of separating plates, and the encapsulation layer define an accommodating cavity. The viewing angle switching assembly includes a sidewall electrode disposed on the separating plate and charged particles having a first electrical polarity disposed in the accommodating cavity. In a private protection mode, the sidewall electrode has a second electrical polarity opposite to the first electrical polarity.
