A light-emitting structure includes a package substrate and a light emitter disposed on the package substrate. The package substrate includes a carrier substrate and a plurality of metal units disposed on the carrier substrate. A distance between two arbitrary points on a periphery of the metal unit is defined as a peripheral endpoint distance. The light emitter includes a first electrical metal and a second electrical metal that have different electrical polarities and are separate from each other. A shortest distance between the first electrical metal and the second electrical metal is defined as an electrical metal interval. The electrical metal interval between the first electrical metal and the second electrical metal is greater than the longest peripheral endpoint distance of the metal unit.
