Description

Substrate, display panel including the same, and electronic device including the same Cross Reference to Related Applications The present application claims priority and rights of korean patent application No. 10-2024-0047216 filed on the korean intellectual property agency at 4/8 of 2024, the entire disclosure of which is incorporated herein by reference. Technical Field Aspects of embodiments of the present disclosure relate to a substrate, a display panel including the substrate, and an electronic device including the display device. Background As technology advances, display devices may include electronic components for performing various functions therein. When the electronic component is driven, at least a portion of electromagnetic waves (e.g., static electricity) may be generated, and the corresponding electromagnetic waves may be introduced into the display device. The above information disclosed in this background section is for enhancement of understanding of the background of the present disclosure and, therefore, it may contain information that does not form the prior art. Disclosure of utility model When the substrate of the display device is formed of plastic, the substrate may be susceptible to static electricity (e.g., may be greatly affected by static electricity). For example, the introduced electromagnetic waves may charge at least a portion of the substrate. Therefore, the operation of the electronic component may be affected, and there may occur a risk that the reliability of the driving of the display device will be lowered.
