Flexible display panel, preparation method thereof and display device

The invention relates to the technical field of display, in particular to a flexible display panel, a preparation method of the flexible display panel and a display device. The flexible display panelis provided with a first bending area and/or a second bending area; neutral layer adjusting layers are arranged at the positions, corresponding to the first bending area and the second bending area, on the flexible display panel, and the neutral layer adjusting layers are used for adjusting the position of a neutral layer in the first bending area to a thin film transistor layer and adjusting theposition of a neutral layer in the second bending area to a packaging layer. According to the flexible display panel, the problem that the thin film transistor layer and the packaging layer of an existing flexible display panel cannot meet the requirements of pulling and pressure stress simultaneously can be solved through the neutral layer adjusting layers. 本发明涉及显示技术领域，特别涉及种柔性显示面板及其制备方法和显示装置。该柔性显示面板具有第弯曲区域和/或第二弯曲区域；在所述柔性显
