Claim 0:
1. An illumination device comprising:
a substrate;
a plurality of light emitting devices disposed on the substrate;
a resin layer surrounding the plurality of light emitting devices;
a first phosphor layer disposed on an upper surface of the resin layer;
a second phosphor layer disposed on different side surfaces of the resin layer; and
a light blocking layer disposed between the first phosphor layer and the second phosphor layer,
wherein the first phosphor layer and the second phosphor layer have different colors,
wherein the first phosphor layer overlaps the plurality of light emitting devices in a vertical direction,
wherein the resin layer is disposed between the plurality of light emitting devices and the first phosphor layer, the resin layer is disposed between side surfaces of the plurality of light emitting devices, and the resin layer is disposed between an outermost light emitting device of the plurality of light emitting devices and the second phosphor layer,
wherein the light blocking layer is disposed on different side surfaces of the first phosphor layer, and
wherein the light blocking layer is disposed along an upper surface of the second phosphor layer disposed on each of the different side surfaces of the resin layer,
wherein the light blocking layer overlaps the resin layer in the vertical direction,
wherein the light blocking layer is disposed on upper corners of the different side surfaces of the resin layer,
wherein the light blocking layer overlaps the second phosphor layer in the vertical direction, and
wherein the light blocking layer is in contact with the different side surfaces of the resin layer.
