Claim 0:
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 four Fresnel lenses disposed above the base member and facing the plurality of light-emitting elements; wherein:
in a top plan view, a center of each of the plurality of light-emitting elements is offset from a lens center of the corresponding one of the Fresnel lenses of the lens in a direction toward a center of the lens;
the plurality of light-emitting elements include at least two first light-emitting elements and at least two second light-emitting elements, wherein an emission color of the first light-emitting elements is different from an emission color of the second light-emitting elements;
each of the first light emitting elements comprises:
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 outer lateral surfaces of the first wavelength conversion member; and

each of the second light emitting elements comprises:
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 and outer lateral surfaces of the second wavelength conversion member.
