NOVELTY - The application claims an OLED display, the OLED display comprises: a substrate; a light shielding layer, the light shielding layer is set on one side of the base plate; a buffer layer, the buffer layer is set on one side of the base plate, and covering the light shielding layer; a thin film transistor, the thin film transistor is set on one side of the buffer layer far away from the base plate, and corresponding to the light shielding layer, the thin film transistor comprises an active layer, a first gate insulating layer, a gate layer and a source/drain layer; a second gate insulating layer, the second gate insulating layer is set on one side of the thin film transistor away from the substrate, the second gate insulating layer comprises a plurality of interval protrusions set, the first protrusion is set corresponding to the source-drain layer; the protective layer graphene set on the second grid insulating layer far away from one side of the base plate. The embodiment of the application can release the stress of the insulating protective layer on the graphene protective layer by setting the first protrusion.
