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.

說明書

The touch insulating film 430 may be formed over the thin film encapsulation layer 300 to cover the touch electrode 410. The touch insulating film 430 may also be formed over the thin film encapsulation layer 300 in the opening portion OP, as illustrated in FIG. 2B. For example, the thin film encapsulation layer 300 and the touch insulating film 430 may be sequentially stacked and formed in the opening portion OP formed in the display unit 200. Because the first inorganic film 310a and the second inorganic film 310b of the thin film encapsulation layer 300 contact each other at an edge of the organic film 330 in the opening portion OP, the first inorganic film 310a, the second inorganic film 310b, and the touch insulating film 430 may be sequentially stacked in a region in the opening portion OP.

The touch insulating film 430 may be an inorganic film formed of an inorganic material, or may be an organic film formed of an organic material. As an alternative embodiment, the touch insulating film 430 may be a single film, or may be a film stack including metal oxide and/or metal nitride. For example, the touch insulating film 430 may include any one of SiNx, Al2O3, SiO2, and/or TiO2.
