Original Abstract Submitted

a light-emitting device includes a first semiconductor layer, a light-emitting functional layer and a second semiconductor layer that are stacked. the first semiconductor layer includes a first semiconductor pattern and a second semiconductor pattern. the light-emitting functional layer includes a first light-emitting pattern and a second light-emitting pattern spaced apart. the second semiconductor layer includes a third semiconductor pattern and a fourth semiconductor pattern spaced apart. orthographic projections of the first semiconductor pattern, the first light-emitting pattern and the third semiconductor pattern on a reference plane at least partially overlap to form a first light-emitting portion. orthographic projections of the second semiconductor pattern, the second light-emitting pattern and the fourth semiconductor pattern on the reference plane at least partially overlap to form a second light-emitting portion. the reference plane is parallel to a plane where the first semiconductor layer is located.
