Abstract
A display panel and a display device are disclosed. The display panel includes a substrate, a light-emitting element, a pixel defining layer corresponding to a non-opening area, an encapsulation layer used to cover the light-emitting element and the pixel defining layer, and an electrically controlled capsule layer including an electrically controlled capsule arranged in an opening area. There are multiple positively or negatively charged black particles inside each electrically controlled capsule. When the light-emitting element emits light or doesn't emit light, the electrically controlled capsule at the corresponding position is in a first state or a second state, respectively. The first state is a light-transmitting state, in which black particles are located on both sides of a light exit surface of the electrically controlled capsule. The second state is a non-light-transmitting state, in which the black particles are located on a light exit surface of the electrically controlled capsule.
