Korean Patent Application No. 10-2018-0108510, filed on Sep. 11, 2018, in the Korean Intellectual Property Office, and entitled: “Display Apparatus,” is incorporated by reference herein in its entirety.
Embodiments relate to a display apparatus.
Since an organic light-emitting display apparatus is a self-emissive display apparatus that does not need an additional light source, the organic light-emitting display apparatus may operate at a low voltage and may be configured as a lightweight thin apparatus. Also, since the organic light-emitting display apparatus has high quality characteristics such as a wide viewing angle, a high contrast ratio, and a fast response time, the organic light-emitting display apparatus has attracted attention as a next-generation display apparatus.
