Abstract

A light-emitting device is provided. The light-emitting device includes a first substrate. The light-emitting device also includes a second substrate including a light-shielding structure. The light-emitting device further includes a first light-emitting module and a second light-emitting module being adjacent to each other. The first light-emitting module and the second light-emitting module are disposed between the first substrate and the second substrate. The first light-emitting module and the second light-emitting module are spaced apart by a gap, and the light-shielding structure at least partially covers the gap in a top view direction of the light-emitting device.
