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

A buffer layer 110 may be first formed over the substrate 100, and then the display unit 200 may be formed over the buffer layer 110. Although FIG. 2A illustrates that the display unit 200 is formed over the buffer layer 110, the inventive concept is not limited thereto, and the display unit 200 may be formed directly over the substrate 100 in an alternative embodiment.

The substrate 100 may include various materials. The substrate 100 may be formed of a transparent glass material having SiO2 as a main component. However, the substrate 100 is not limited thereto, and may also be formed of a transparent plastic material. The plastic material may be an organic material selected from the group consisting of polyethersulphone (PES), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyallylate, polyimide, polycarbonate (PC), cellulose triacetate (TAC), and/or cellulose acetate propionate (CAP), which are insulating organic materials.
