The invention discloses a display panel, comprising: a first substrate including a display region and a peripheral region adjacent to each other; a plurality of pixel units disposed on the first substrate and located in the display region; a planarization layer disposed on the first substrate and located in the display region and the peripheral region; and an organic passivation layer disposed on the first substrate, covering the planarization layer and located in the display region and the peripheral region; wherein the planarization layer further comprises a first region planarization layer located in the display region, and a second region planarization layer located in the peripheral region, the first region planarization layer is formed with a first sidewall in a boundary region between the display region and the peripheral region, and a height of the first sidewall is greater than a height of the first region planarization layer. The invention can effectively reduce probability of the organic passivation layer on sidewalls of the passivation layers, and can better avoid moisture from penetrating the organic material into the display panel.
