Abstract:
A light-emitting device includes a substrate; at least one light-emitting element on or above the substrate; a plate-shaped light-transmissive member having a lower surface that faces an upper surface of the at least one light-emitting element; a covering member that covers a lateral surface of the at least one light-emitting element and a lateral surface of the light-transmissive member; and a light-guiding member that is disposed between the light-emitting element and the light-transmissive member. In a plan view, a first lateral side of an upper surface of the light-transmissive member is outside a first lateral side of the upper surface of the at least one light-emitting element, and a second lateral side of the upper surface of the light-transmissive member is inside a second lateral side of the upper surface of the at least one light-emitting element.
