Abstract

A display panel is provided, which includes a light-emitting structure. The light-emitting structure includes an anode positioned on a thin film transistor layer, a luminescent material layer positioned on the anode, and a cathode covering the luminescent material layer. The light-emitting structure further includes a cathode reflective layer and a quantum dot film. The cathode reflective layer is positioned above the cathode and is electrically insulated from the cathode by a reflective isolation layer. The quantum dot film is positioned in the reflective isolation layer that is between the cathode and the cathode reflective layer.
