Claim 0:
1. A light-emitting device comprising:
a substrate;
at least one light-emitting element on or above the substrate, the at least one light-emitting element having a rectangular shape in a plan view from above the light-emitting device and having an upper surface serving as a light-emitting surface of the at least one light-emitting element;
a plate-shaped light-transmissive member having a rectangular shape in a plan view from above the light-emitting device and having a lower surface that faces the 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,
wherein the upper surface of the at least one light-emitting element with the rectangular shape has a first lateral side and a second lateral side opposite to each other, and a third lateral side and a fourth lateral side opposite to each other,
wherein an upper surface of the light-transmissive member with the rectangular shape has a first lateral side and a second lateral side opposite to each other, and a third lateral side and a fourth lateral side opposite to each other,
wherein the light-transmissive member is disposed on or above the at least one light-emitting element such that, in a plan view from above the light-emitting device:
the first lateral side of the upper surface of the light-transmissive member is outside the first lateral side of the upper surface of the at least one light-emitting element, and no light-emitting element in the light emitting device overlaps the first lateral side of the upper surface of the light-transmissive member, and
the second lateral side of the upper surface of the light-transmissive member is inside the second lateral side of the upper surface of the at least one light-emitting element, and

wherein the light-guiding member is disposed at the lateral surface of the at least one light-emitting element on the first lateral side of the upper surface of the at least one light-emitting element, and the covering member is disposed at the lateral surface of the at least one light-emitting element on the second lateral side of the upper surface of the at least one light-emitting element.
