WIPO Patent Application WO/2020/258897

A1

Disclosed in the present application are a display panel, a display device, and a manufacturing method for the display panel. The display panel comprises: a driving backplane; and a light-emitting component layer, provided on the driving backplane, and comprising a plurality of light-emitting units distributed in an array and barriers. Two adjacent light-emitting units are separated from each other by one barrier, and the light-emitting units at least comprise a first primary color light-emitting unit, a second primary color light-emitting unit, and a third primary color light-emitting unit; at least the first primary color light-emitting unit and the second primary color light-emitting unit are provided with a light conversion unit, and the light conversion unit comprises more than two layers of light conversion layers stacked in a thickness direction of the display panel; a first transparent thermally conductive layer is provided between two layers of adjacent light conversion layers. The display panel provided in embodiments of the present application can improve the heat dissipation performance of a light conversion material, avoid a short service life of the light conversion material caused by high temperature, and further avoid affecting the display effect of the display panel.
