A light-emitting element comprises a substrate, a light shielding layer, a capping layer and a plurality of protrusions. The light shielding layer is above the substrate. The capping layer is above the light shielding layers. The plurality of protrusions is arranged over the substrate, an organic light-emitting unit comprising an organic material being disposed between two adjacent protrusions of the plurality of protrusions. An edge of the light shielding layer is misaligned with an edge of one of the plurality of protrusions. The organic light-emitting unit includes a first light-emitting unit and a second light-emitting unit. The first light-emitting unit and the second light-emitting unit respectively have an organic light-emitting stack layer comprising an organic material.
