Abstract

A flexible display panel, a flexible display device and a method of forming the flexible display panel are provided. The flexible display panel includes: a substrate; thin film transistors arranged in an array on the substrate; an electroluminescent device arranged on the thin film transistors and driven by the thin film transistors, including a pixel defining layer and an electroluminescent material defined by the pixel defining layer; a thin film encapsulation layer on the electroluminescent device; a quantum dot photoconversion layer on the thin film encapsulation layer, including an isolation portion and a quantum dot luminescent material surrounded by the isolation portion, where an orthographic projection of the isolation portion onto the substrate covers an orthographic projection of the pixel defining layer onto the substrate; and a cover plate arranged on the quantum dot photoconversion layer.
