Abstract: A pixel structure including a substrate, an active device, a planarization layer, a pixel electrode, and a patterned protection layer is provided. The active device is disposed on the substrate. The planarization layer is disposed on the substrate and covers the active device. The pixel electrode is disposed on the planarization layer and electrically connected to the active device. The patterned protection layer is disposed on the planarization layer and laterally surrounds the pixel electrode, and both the patterned protection layer and the pixel electrode are in contact with the planarization layer.
