LED backlight device and LCD device |
摘要 |
A backlight device includes a first substrate, and an LED thin-film layered structure (epitaxially grown inorganic material layers) fixed to a surface of the first substrate. An anode electrode and a cathode electrode are formed on the LED thin-film layered structure. An anode driver IC and a cathode driver IC are provided for driving the LED thin-film layered structure. A wiring structure electrically connects the anode driver IC and the anode electrode of the LED thin-film layered structure, and electrically connects the cathode driver IC and the cathode electrode of the LED thin-film layered structure. A second substrate has an optical transparency and is disposed to face the surface of the first substrate on which the LED thin-film layered structure is formed. A phosphor is formed on a surface of the second substrate facing the first substrate and is disposed on a position corresponding to the LED thin-film layered structure.
