1. A light-emitting device comprising:
a plurality of light-emitting elements arranged in an array on a base member; and
a lens that comprises at least one lens part disposed above the base member and comprising a first surface that faces the plurality of light-emitting elements, the first surface comprising a plurality of protrusions; wherein:
the plurality of light-emitting elements include:
a first light-emitting element having a center that faces a lens center of the lens in a top view, the first light-emitting element comprising:
a first light-emitting diode,
a first wavelength conversion member having an upper surface, a lower surface, and lateral surfaces that extend between the upper surface and the lower surface, wherein the lower surface of the first wavelength conversion member is bonded to an upper surface of the first light-emitting diode, and
a first protective member having inner surfaces that cover outer lateral surfaces of the first light-emitting diode, and
a second light-emitting element having a center offset from the lens center of the lens in the top view, the second light-emitting element comprising:
a second light-emitting diode,
a second wavelength conversion member having an upper surface, a lower surface, and lateral surfaces that extend between the upper surface and the lower surface, wherein the lower surface of the second wavelength conversion member is bonded to an upper surface of the second light-emitting diode, and
a second protective member having inner surfaces that cover outer lateral surfaces of the second light-emitting diode, wherein:
the second protective member is separated from the first protective member, and
a red component of light emitted from the second light-emitting element is greater than a red component of light emitted from the first light-emitting element.
