FIG. 8 is a conceptual diagram of the portion D of FIG. 1, according to an exemplary embodiment. The display apparatus according to the exemplary embodiment of FIG. 8 is different from the display apparatus described with reference to FIG. 5 in that the display apparatus according to the exemplary embodiment of FIG. 8 has a different shape with respect to the second insulating layer 150.

The display apparatus according to the exemplary embodiment of FIG. 8 includes the first insulating layer 140 and the second insulating layer 150. As described above with reference to FIG. 5, the first insulating layer 140 covers a portion of the substrate 100. For example, the first insulating layer 140 covers a portion of the substrate 100 that is closer to the center of the substrate 100 than the electrode power supply line VSS, and also covers a portion of the electrode power supply line VSS. In this regard, the first insulating layer 140 covers the first portion P1 and a portion of the second end EP2 of the electrode power supply line VSS. The first end EP1 is disposed on the electrode power supply line VSS. The second insulating layer 150 that covers the first insulating layer 140 includes the second end EP2, which is disposed on the electrode power supply line VSS.
