Electro-optical device, image forming apparatus, and image reader
View Patent ↗An electro-optical device includes a substrate, a plurality of self-emitting elements formed in the substrate, a sealing member attached to the substrate so as to seal the self-emitting elements in cooperation with the substrate, and a circuit that is disposed to overlap the sealing member and that drives or controls the self-emitting elements.
1. An electro-optical device comprising:
a substrate;
a plurality of emitting elements formed on the substrate;
a sealing member attached to the substrate so as to seal the emitting elements in cooperation with the substrate, the sealing member having an outer surface facing away from the emitting elements;
a circuit that is attached to the outer surface of the sealing member and that drives or controls the emitting elements, the circuit having an outer surface facing away from the sealing member;
a power line provided on the substrate;
an electrode on the outer surface of the circuit; and
a bonding wire connecting the power line to the electrode.
2. An image reader comprising:
the electro-optical device, according to claim 1 , having a plurality of the emitting elements arrayed therein; and
a light receiver that receives light emitted from the emitting elements and reflected from an object to be read, and converts the reflected light into electrical signals.
