Abstract
A display panel, a display device, and a manufacturing method of the display panel are disclosed. The display panel includes: a light emitting element including a microcavity structure and a light emitting layer disposed in the microcavity structure; and an external microcavity structure disposed on a light emitting side of the light emitting element and including a first transflective layer, a second transflective layer and a dielectric layer disposed between the first transflective layer and the second transflective layer. The microcavity structure can modulate a spectrum of light emitted by the light emitting layer in the first viewing angle range; the external microcavity structure can modulate a spectrum of light emitted by the light emitting element in the second viewing angle range; and the second viewing angle range is greater than the first viewing angle range.
