1. A light-emitting device comprising:
a substrate comprising a first surface;
a light-emitting unit located over the first surface of the substrate;
a terminal located over the first surface of the substrate, and electrically connected to the light-emitting unit;
a sealing layer sealing the light-emitting unit and not covering the terminal, the sealing layer comprising a first end portion located between the light-emitting unit and the terminal as viewed in a first direction perpendicular to the substrate; and
