Abstract:
1. An LED backlight device comprising: a first substrate; an LED thin-film layered structure fixed to a surface of said first substrate, said LED thin-film layered structure being formed of epitaxially grown inorganic material layers as a P-N junction device; an anode electrode and a cathode electrode formed on said LED thin-film layered structure; an anode driver IC and a cathode driver IC for driving said LED thin-film layered structure; a wiring structure that electrically connects said anode driver IC and said anode electrode of said LED thin-film layered structure, and electrically connects said cathode driver IC and said cathode electrode of said LED thin-film layered structure; a second substrate having an optical transparency and disposed to face said surface of said first substrate on which said LED thin-film layered structure is formed, and a phosphor formed on a surface of said second substrate facing said first substrate and disposed on a position corresponding to said LED thin-film layered structure.
