Flexible circuit board and foldable electronic device comprising same

Abstract

An electronic device can include a hinge structure; a flexible display which is folded or unfolded by the hinge structure; a first portion and a second portion which are close to and facing each other when folded by the hinge structure, and spaced apart when unfolded; a first circuit board disposed on the first portion; a second circuit board disposed on the second portion; and a flexible circuit board electrically connecting the first printed circuit board and the second circuit board. The flexible printed circuit board includes a first area which bends in response to the deformation of the electronic device, and a second region positioned around the first region that does not bend. The first region may include a single main signal wiring layer. The second portion may include a plurality of signal wiring layers. The first region and the second region may be formed to have different thicknesses.
