Patent ID: 7323720

Claim:
A light-emitting device, comprising: a substrate having a first surface and a second surface; a light emission region arranged over the first surface of the substrate, a plurality of light-emitting elements each having a cathode and an anode and being located in the light emission region, light being emitted in a light-emitting direction from the light emission region; at least one integrated circuit chip that generates signals to control the plurality of light-emitting elements and that have a plurality of output terminals to output signals to the plurality of light-emitting elements, a plurality of connection terminals connected to the plurality of output terminals of the integrated circuit chip; a common cathode line connected to the cathode of each of the plurality of light-emitting elements; and first wiring lines that connect the anodes of the plurality of light-emitting elements to the plurality of connection terminals, the integrated circuit chip being connected to the substrate so as to overlap at least a portion of the light emission region, as viewed from a position in the light-emitting direction, the integrated circuit chip being fixed to the first surface of the substrate by the plurality of output terminals, each of the plurality of terminals having a length such that the bottom of the integrated circuit chip does not contact the light-emitting region, and the plurality of light-emitting elements being interposed between the plurality of connection terminals and the common cathode line.
