Abstract: A display panel includes a driving backplane, an optical device layer, an adhesive layer and an optical conversion layer. The optical device layer includes optical devices each including a buffer layer and at least one light emitting unit. The buffer layer includes a first surface and a second surface. The first surface is farther away from the driving backplane than the second surface. The light-emitting unit is located on a side of the second surface away from the first surface. A buffer layer of at least one optical device further includes a side surface for connecting a first surface and a second surface. The side surface intersects with the first surface to form a first acute angle, and the side surface intersects with the second surface to form a first obtuse angle. A refractive index of the adhesive layer is less than a refractive index of the buffer layer.
