[0069] figure 1 It is an equivalent circuit diagram showing the electrical configuration of the organic EL device. Below, while referring to figure 1 , the configuration of the organic EL device will be described. Here, the organic EL device according to this embodiment will be described as an example with a bottom emission structure, but it can also be used with a top emission structure.
[0070] Such as figure 1 As shown, for the organic EL device 11, a plurality of scanning lines 12, a plurality of signal lines 13 extending in a direction crossing the scanning lines 12, and a plurality of power supply lines 14 extending in parallel with the signal lines 13 are respectively wired in a grid shape. Furthermore, a region divided by the scanning line 12 and the signal line 13 constitutes a pixel region. The signal line 13 is connected to a signal line drive circuit 15 . And the scanning line 12 is connected to the scanning line driving circuit 16 .
