Also, because the barrier B is formed by partially removing the touch insulating film 430 and the thin film encapsulation layer 300 that are arranged at an edge of the portion for formation of the hole H before the forming of the hole H, even if a crack occurs, the propagation of the crack may be reduced or prevented.

FIGS. 5A to 5C are sequential cross-sectional views illustrating a method of manufacturing a display apparatus according to another embodiment. Herein, for conciseness, differences from the display apparatus manufacturing method illustrated in FIGS. 4A to 4D will be mainly described, and like reference numerals will denote like elements, and thus redundant descriptions thereof will be omitted.

First, referring to FIG. 5A, a display unit 200 including an opening portion OP, a thin film encapsulation layer 300, a touch electrode 410, and a touch insulating film 430 may be sequentially formed over a substrate 100.

Thereafter, when a touch contact hole(s) TCH is formed, the touch insulating film 430 and the thin film encapsulation layer 300 in the opening portion OP may be partially removed to form a barrier B. As an alternative embodiment, a valley V partially exposing the substrate 100 may be additionally formed in the barrier B.

Thereafter, a touch line 450 may be formed in/over the touch contact hole(s) TCH. The touch line 450 may contact the touch electrode(s) 410 through the touch contact hole(s) TCH.

Next, referring to FIG. 5B, a passivation layer 500 may be formed to cover the barrier B.
