Abstract: Disclosed are a quantum dot display panel, a manufacturing method thereof and a display device. The manufacturing method includes: forming a first functional layer on a substrate; processing the first functional layer so that the first functional layer includes a processed region and the processed region includes ions having a first polarity; forming a quantum dot layer having a second polarity in the processed region. The second polarity and the first polarity are opposite electrical polarities.

Abstract: A ligand includes a molecular skeleton, a first coordinating group connected to the molecular skeleton, at least one initial group connected to the molecular skeleton, and a protecting group connected to an end of each initial group away from the molecular skeleton. Each initial group is capable of forming a second coordinating group after deprotection.
