要約
(EN)
A three-dimensional LED substrate comprising: at least one LED element; a silicon substrate on which the LED element is mounted through a microbump and which has, formed therein, a wiring line that is connected to the microbump; a heat-insulating organic substrate which is bound to a surface of the silicon substrate which is opposed to the surface having the LED element mounted thereon, and which has a through-hole through which the wiring line is passed; a chip-mounting substrate which is bound to a surface of the heat-insulating organic substrate which is opposed to the silicon substrate side surface, and which has, formed therein, a wiring line that is connected to the wiring line placed in the through-hole in the heat-insulating organic substrate; and an LED control circuit chip which is connected to the wiring line in the chip-mounting substrate through the microbump, and which is mounted on a surface of the chip-mounting substrate which is opposed to the heat-insulating organic substrate side surface through the microbump.
