Display panel, manufacturing method thereof and display device

A display panel, comprising:

• a display region and a lens region, wherein the lens region comprises a common electrode and a deflection electrode arranged opposite each other, and a first liquid crystal layer arranged between the common electrode and the deflection electrode, the deflection electrode is configured for providing at least two different deflection voltages, and the at least two different deflection voltages are configured for deflecting the first liquid crystal layer,
• wherein the display region of the display panel comprises a second liquid crystal layer, the first liquid crystal layer and the second liquid crystal layer are arranged at a same layer, and the first liquid crystal layer and the second liquid crystal layer are separated from each other by an isolation structure,
• wherein the isolation structure comprises a barrier that is made of sealant,
• wherein the isolation structure further comprises a photo spacer that is arranged at a side of the barrier proximate to the first liquid crystal layer.
