Abstract
The disclosure provides an electronic device having an electromagnetic shielding structure for preventing an antenna performance degradation. The disclosed electronic device may include: an antenna disposed in some areas of the electronic device; a printed circuit board; and a display module including a display panel, one or more signal lines coupled to the display panel, and a flexible substrate on which the one or more signal lines are disposed. The flexible substrate may include: a conductive layer coupled to the printed circuit board in a curved state and configured to shield an electromagnetic wave radiated from the one or more signal lines to the antenna; and a stress neutralization layer of which a material can be deformed over time in response to a shape of the flexible substrate coupled in a curved state. The stress neutralization layer may be disposed between the flexible substrate and the conductive layer.
