An electroluminescent device, wherein the electroluminescent device includes a first-conductivity-type semiconductor layer, a second-conductivity-type semiconductor layer, an active layer, a first electrode, a second electrode, and an optical conversion material. The active layer is disposed between the first-conductivity-type semiconductor layer and the second-conductivity-type semiconductor layer and electrically connected with these two. The first-conductivity-type semiconductor layer has a light-emitting surface disposed on a side opposite to the active layer, and includes a plurality of 3D structures arranged regularly, extending from the light-emitting surface towards the active layer to jointly define at least one cavity having a depth greater than 70% a thickness of the first-conductivity-type semiconductor layer. The optical conversion material is filled in the cavity.

A light-emitting device includes a substrate, an active device, a first light-shielding layer, a transparent electrode, a second light-shielding layer, a light-converting layer, an electroluminescent structure, and a top electrode. The active device is located on the substrate. The first light-shielding layer is disposed on the active device and has a first opening. The transparent electrode is located on the first light-shielding layer and electrically connected to the active device. The second light-shielding layer is located on the transparent electrode and has a second opening corresponding to the first opening. The light-converting layer is substantially located in the first opening. The electroluminescent structure is substantially located in the second opening. The transparent electrode is located between the first opening and the second opening. The electroluminescent structure is located between the top electrode and the transparent electrode.
