This application claims priority to Korean Patent Application No. 10-2020-0177817, filed on Dec. 17, 2020, and all the benefits accruing therefrom under 35 U.S.C. § 119, the content of which in its entirety is herein incorporated by reference.
Embodiments relate to display apparatuses.
Display apparatuses visually display data. The display apparatuses are used as displays in small products such as cell phones, or may be used as displays in large products such as televisions.
A display apparatus includes a plurality of pixels that receive an electrical signal and emit light to display an image to the outside. Each of the pixels includes a light-emitting element. An organic light-emitting display apparatus includes an organic light-emitting diode (“OLED”) as a light-emitting element, for example. In general, the organic light-emitting display apparatus with a thin-film transistor and an OLED formed on a substrate, and the OLED emits light by itself.
Recently, as a use of display apparatuses is being diversified, various designs for improving quality of display apparatuses are being attempted.
Embodiments provide a display apparatus that is capable of preventing a pixel defect from occurring due to static electricity generated from the outside.
The technical feature of the invention is not limited to the technical feature described above, and other technical features not mentioned will be clearly understood by a person skilled in the art from the description of the invention.
