Official abstract text for this publication.
A flexible substrate is disclosed. The flexible substrate includes an insulating substrate having a first surface and a second surface opposite to the first surface, a first connection portion having a first conductor, a first ground pattern, and a second ground pattern on the first surface, the first ground pattern and the second ground pattern being spaced apart from the first conductor and respectively located at either side of the first conductor, a conductor pattern formed on the second surface, the conductor pattern being connected to the first conductor, and a third ground pattern formed on the second surface, the third ground pattern being connected to the first ground pattern, wherein a distance between the conductor pattern and the third ground pattern is smaller than a distance between the first conductor and the first ground pattern.
