1. A lighting device comprising:
a substrate;
a light emitting device disposed on the substrate;
a first reflective member disposed on the substrate;
a resin layer disposed on the first reflective member; and
a wavelength conversion layer disposed on the resin layer,
wherein the resin layer comprises;
a first resin layer;
a second resin layer spaced apart from the first resin layer; and
a third resin layer disposed between the first and second resin layers,
wherein the wavelength conversion layer comprises;
a first wavelength conversion layer disposed on the first resin layer; and
a second wavelength conversion layer disposed on the second resin layer,
wherein a height of the second resin layer is lower than a height of the first resin layer,
wherein the light emitting device is disposed in a region that does not overlap the second and third resin layers in a vertical direction but overlaps the first resin layer in the vertical direction,
wherein the light emitting device is embedded in a lower portion of the resin layer,
wherein the first wavelength conversion layer absorbs light emitted from the light emitting device and converts it into first light of a first wavelength band,
wherein the second wavelength conversion layer absorbs light incident through the second resin layer and the third resin layer and converts it into second light,
wherein the second light has a different color from the first light, and
wherein a portion of the light emitted from the light emitting device is emitted as third light through a side surface of the first resin layer facing an upper surface of the third resin layer.
