Abstract
Provided are an electronic paper display panel and a display device. The electronic paper display panel includes a first substrate and a second substrate opposite to each other and a plasma layer between the first substrate and the second substrate. The plasma layer includes an electrophoretic fluid and first-type charged particles. The first-type charged particles have charges with a first electrical property. The first-type charged particles include first charged subparticles and second charged subparticles. The particle size of a first charged subparticle is D1. The particle size of a second charged subparticle is D2. The charge quantity carried by the first charged subparticle is q1. The charge quantity carried by the second charged subparticle is q2. (D1-D2)×(q1-q2)>0.
