Abstract
An optoelectronic device includes a substrate, a light emitting/receiving unit, a mask, a light shielding layer, and a first light-transmissive component. The light emitting/receiving unit is disposed on the substrate and includes an emitting/receiving side and a metal pattern disposed on the emitting/receiving side. The emitting/receiving side has an active area, and the metal pattern surrounds the active area. The mask covers the metal pattern. The light shielding layer is disposed on the substrate and surrounds the light emitting/receiving unit. The first light-transmissive component covers the light emitting/receiving unit, the mask, and the light shielding layer.
