Abstract:
A light emitting device including a first light emitting element that includes a first electrode having a first polarity and a second electrode having a second polarity that is different from the first polarity. The device has a circuit element that includes a main body, and first and second terminals electrically connected with one another via the main body. The device includes a first wiring having the first polarity connecting the first electrode of the first light emitting element and the first terminal, and a second wiring having the second polarity located in a layer common with a layer of the first wiring and including a portion elongated between the first terminal and the second terminal in a bottom view. An upper surface of the main body is positioned at a distance below an interface between a lower surface of the first wiring and the first electrode.
