To reduce the size of a light emission device in comparison to a case where an electrode unit is arranged in the longitudinal direction of the light emission device.SOLUTION: A light emission device comprises: a substrate; a light emission unit which is made of a plurality of light emission elements; a transfer unit which outputs a signal with which the light emission states of the light emission elements sequentially propagate; and electrode units for inputting/outputting signals for driving the transfer unit. The substrate is in a rectangular shape having the long sides and the short sides and the electrode units are arranged along the short sides of the substrate with the transfer unit held therebetween. The electrode units each have a transfer signal electrode applied with a transfer signal for transferring the light emission states of the light emission elements in the control order, and a power source electrode which applies a power source potential and a reference potential to the transfer unit. The transfer signal electrodes and the power source electrodes are arranged in plurality on the same straight line with respect to the transfer unit.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、発光装置のサイズを小さくする。【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が順に伝播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、電極部は、転送部を挟んで、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を制御順に転送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電源電極を有し、転送信号電極及び電源電極は、転送部に対して、同一直線状に複数配置されている。【選択図】図１
