Abstract
A display panel and a display device are provided. The display panel includes a first substrate; a light-emitting layer; and a light modulation layer. The light-emitting layer is located between the first substrate and the light modulation layer; the light modulation layer includes a first light modulation layer and a second light modulation layer; the light-emitting layer includes at least one light-emitting element; the first light modulation layer includes at least one first opening; an orthographic projection of the first opening on the first substrate overlaps an orthographic projection of the light-emitting element on the first substrate; the second light modulation layer covers the first opening; and a refractive index of the second light modulation layer is greater than a refractive index of the first light modulation layer.
