PLANAR LIGHT EMITTING DEVICE

摘要

In the present invention a plurality of electric-power-supply units (electricity-supplying auxiliary electrodes (27a-27e)) are formed along one side of a transparent substrate (11) that describes a rectangular shape in planar view, and an electric-power-supply unit (electricity-supplying auxiliary electrode) is formed along a side parallel to the one side. A connecting substrate (40) is connected to the electric-power-supply unit by a connecting member. On the connecting substrate (40) are formed five connecting electrodes (43a-43e) on a main surface opposing the plurality of electric-power-supply units, and five connecting terminals (42a-42e) on a main surface of the side opposite the main surface of the connecting substrate (40) opposing the plurality of electric-power-supply units. The five connecting terminals (42a-42e) and the five connecting electrodes (43a-43e) are electrically connected by an anode bus line (44) or a cathode bus line (45). The plurality of electric-power-supply units (auxiliary electrodes 27a, 27c, 27e) are electrically connected to each other via the anode bus line (44) of the connecting substrate (40), and the electric-power-supply units (electricity-supplying auxiliary electrodes (27b, 27d)) are electrically connected to each other via the cathode bus (45) line of the connecting substrate (40).
