Abstract: A light emitting device and a keyboard structure are provided. The light emitting device includes a circuit board and multiple light emitting units. The circuit board includes a substrate, a first conductive pad, multiple second conductive pads, and multiple third conductive pads. The first conductive pad and the second conductive pads are disposed on a first board surface of the substrate. The first conductive pad has a symmetrical shape and a symmetrical axis. The symmetrical axis passes through the second conductive pads. The third conductive pads are disposed on a second board surface of the substrate. Each of the third conductive pads is electrically coupled to the first conductive pad and the second conductive pads by multiple conductive columns. Each of the light emitting units is connected to the first conductive pad and one of the second conductive pads.
