Organic EL display device
View Patent ↗An organic EL display device includes a substrate on which a plurality of driver transistors are formed, a first wiring that supplies an electric voltage in accordance with a display image via one of the driver transistors, an organic EL film that emits light, an anode electrode, and an auxiliary electrode film including a first low resistance part, a second low resistance part separated from the first low resistance part, and a high resistance part disposed between the first low resistance part and the second low resistance part. The first low resistance part is electrically connected to the first wiring and the anode electrode. The second low resistance part forms an electrostatic capacitance between the anode electrode and itself. The high resistance part has an electric resistance higher than those of the first low resistance part and the second low resistance part.
