To shorten the length of a light emitting device in the longitudinal direction compared to a case where an electrode portion is arranged in the longitudinal direction of the light emitting device.SOLUTION: A light emitting device includes a substrate, a light-emitting portion composed of a plurality of light-emitting elements, a transfer unit that outputs a signal for controlling the light emitting state of the light emitting element, and an electrode unit for inputting/outputting the signal to drive the transfer unit, the substrate has a rectangular shape with long sides and short sides, and the transfer unit and the electrode unit are arranged along the short sides of the substrate, respectively. The electrode unit includes a transfer signal electrode to which a transfer signal for controlling a state in which the light-emitting element can shift to a light-emitting state is applied, and a transfer power supply electrode for applying power supply potential and reference potential to the transfer unit, and the transfer signal electrode and the transfer power supply electrode are arranged side by side along the short side of the substrate.SELECTED DRAWING: Figure 1 【課題】電極部を発光装置の長手方向に配置する場合と比較して、発光装置の長手方向の長さを短くする。【解決手段】基板と、複数の発光素子からなる発光部と、発光素子の発光状態を制御する信号を出力する転送部と、転送部を駆動する信号を入出力するための電極部と、を備え、基板は、長辺と短辺とを有する長方形状であり、転送部及び前記電極部は、それぞれが基板の短辺に沿って配置されている。電極部は、発光素子の発光状態に移行可能な状態を制御させる転送信号が与えられる転送信号電極 、転送部に電源電位及び基準電位を与える転送電源電極を有し、転送信号電極及び転送電源電極は、基板の短辺に沿って並んで配置されている。【選択図】図１
