Claim 17:
18. A light-emitting diode device, comprising:
a first epitaxial layered structure which emits light of a first wavelength range, and which has an upper surface having a first region and a second region different from said first region;
a second epitaxial layered structure which emits light of a second wavelength range different from the first wavelength range, which is spaced-apart disposed on said upper surface of said first epitaxial layered structure, and which has a band gap smaller than that of said first epitaxial layered structure;
a light conversion layer that is formed on said first region of said upper surface of said first epitaxial layered structure and that is configured to be excited by light of the first wavelength range emitted from the first epitaxial layered structure to emit light of a third wavelength range different from the first wavelength range;
a bonding unit that is disposed on said light conversion layer and that is configured to allow light of the third wavelength range emitted from said light conversion layer to pass therethrough and, said bonding unit and said light conversion layer interconnecting said first and second epitaxial layered structures; and
an electrically conductive structure that is formed on said second region of said upper surface of said first epitaxial layered structure and that electrically connects said first epitaxial layered structure to said second epitaxial layered structure,
wherein said upper surface of said first epitaxial layered structure further has a third region that is different from said first and second regions and that is exposed from said light conversion layer and said electrically conductive structure, and said bonding unit is formed on a portion of said light conversion layer such that the remainder of said light conversion layer is exposed from said bonding unit.
