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.

No. 16/572,462, filed on Sep. 16, 2019, now U.S. Pat. No. 10,680,205, which is a continuation of U.S. patent application Ser. No. 16/273,042, filed on Feb. 11, 2019, now U.S. Pat. No. 10,431,772, which is a divisional of U.S. patent application Ser. No. 15/298,082, filed Oct. 19, 2016, now U.S. Pat. No. 10,230,069, which claims priority to and the benefit of Korean Patent Application No. 10-2016-0016360, filed Feb. 12, 2016, the entire contents of all of which are incorporated herein by reference.

BACKGROUND 1. Field

One or more embodiments relate to display apparatuses, and to methods of manufacturing the same.

2. Description of the Related Art

Recently, display apparatuses have been used for various purposes. Also, display apparatuses are widely used because they have become thin and lightweight. In particular, flat-panel display apparatuses have recently been extensively researched and manufactured. Because display apparatuses may be formed in the shape of a flat panel, the shapes of display apparatuses may be designed in various ways. Also, an increasing number of functions may be incorporated into, or associated with, the display apparatuses.

SUMMARY

One or more embodiments include display apparatuses having reduced occurrence of cracking and reduced propagation of cracks, and also include methods of manufacturing the same.
