摘要

A method of manufacturing a display apparatus includes providing a substrate, forming a display unit defining an opening portion in a display region over the substrate, forming a thin film encapsulation layer to seal the display unit, forming a touch electrode over the thin film encapsulation layer, forming a touch insulating film covering the touch electrode such that the thin film encapsulation layer and the touch insulating film are sequentially stacked and formed over the substrate in the opening portion, forming a touch contact hole by removing a portion of the touch insulating film to expose a portion of the touch electrode, and removing a portion of the touch insulating film and a portion of the thin film encapsulation layer formed in the opening portion to expose a portion of the substrate during the forming of the touch contact hole.

The number of upper dams 600 is not limited, and the upper dam 600 may be formed to have a certain height to function as a dam as described later.

FIG. 6A illustrates that the upper dam 600 is formed at a position corresponding to an edge of the opening portion OP (e.g., to be at least partially within the opening portion OP). However, the formation position of the upper dam 600 is not limited thereto, and the upper dam 600 may be formed at any position over the thin film encapsulation layer 300 as long as it functions as a dam.

Next, referring to FIG. 6B, a buffer layer 350 may be formed over the thin film encapsulation layer 300. In this case, the upper dam 600 may reduce or prevent the buffer layer 350 from spreading or leaking to the opening portion OP.

As described above, the display unit 200 may include a light-emitting device, such as an organic light-emitting device (OLED), and the light-emitting device may include an electrode.
