FIG. 11 is a cross-sectional view of the display apparatus of FIG. 1 taken along line A-A′ of FIG. 1 and line B-B′ of FIG. 2, according to an exemplary embodiment. In the above, a case in which the second end EP2 of the second insulating layer 150 on the electrode power supply line VSS contacts the electrode power supply line VSS has been described, however, the present disclosure is not limited thereto. For example, as illustrated in FIG. 11, in an exemplary embodiment, the second end EP2 of the second insulating layer 150 disposed over the electrode power supply line VSS may be disposed on the first insulating layer 140. Since both the second insulating layer 150 and the first insulating layer 140 include organic materials, adhesion between the first insulating layer 140 and the second insulating layer 150 is high. Thus, even when air is applied thereto by using an air gun, the second end EP2 of the second insulating layer 150 may be efficiently prevented from being chipped off.

FIG. 11 illustrates a modified exemplary embodiment of FIG. 3, but as illustrated in FIG. 12, which is a modified exemplary embodiment of FIG. 9, the second end EP2 of the second insulating layer 150 disposed over the electrode power supply line VSS may be modified to be on the first insulating layer 140.
