Abstract: Disclosed are a display panel and a display apparatus. The display panel includes: a light-emitting base substrate comprising a plurality of light-emitting elements and configured to emit a first light; a color conversion substrate comprising a plurality of color conversion patterns, the color conversion pattern comprising a matrix material and quantum dots dispersed in the matrix material, wherein the matrix material is configured to excite a second light under irradiation of the first light, and the quantum dots are configured to emit light under irradiation of the first light and the second light. By exciting the quantum dots with the light emitted by the light-emitting elements and the light emitted by the matrix material, the luminous efficiency of the quantum dots can be improved and the power consumption can be reduced.

Abstract: A display panel includes a light-emitting substrate, an opposite substrate, and an intermediate layer assembly between the light-emitting substrate and the opposite substrate. The light-emitting substrate has a light-emitting surface configured to allow light to be emitted from, and the light emitted from the light-emitting surface is directed to the opposite substrate. The intermediate layer assembly includes a thin film encapsulation layer, a filler layer, and an overcoat that are sequentially stacked in a pointing direction vertically pointing from the light-emitting substrate to the opposite substrate. The thin film encapsulation layer includes at least two encapsulation sub-layers that are stacked in the pointing direction. In the pointing direction, refractive indexes of the encapsulation sub-layers gradually increase. A refractive index of the overcoat is higher than a refractive index of the filler layer.
