Abstract
One aspect of the present disclosure provides a display panel and a display device. The display panel includes an array substrate, an opposite substrate disposed opposite to the array substrate, and a sieve plate between the array substrate and opposite substrate. The sieve plate includes sieve holes penetrating the sieve plate along the thickness direction of the display panel. The display panel further includes electrophoretic particles that include first-color electrophoretic particles. The particle size of at least one of the first-color electrophoretic particles is smaller than the size of the sieve hole. The first-color electrophoretic particle may freely pass through the sieve hole toward the output surface of the display panel.
Claims19
