Abstract: A foldable electronic device is provided. The foldable electronic device includes a foldable housing including multiple housings and at least one hinge configured to rotatably couple the multiple housings, the folding housing being folded around the hinge, and a flexible display disposed on the foldable housing so as to be folded according to a folding operation of the foldable housing, wherein the flexible display includes a panel layer configured to display image information, a glass layer positioned above the panel layer with reference to a direction in which the image information is displayed, the glass layer being folded when the flexible display is folded, a folding region positioned on a folding part of the glass layer, the folding region including multiple through-holes formed to penetrate the glass layer in the thickness direction and arranged regularly on a surface of the glass layer, and a rib, which is a region between the multiple through-holes adjacent to each other, a flexible polymer region including a transparent and elastic flexible polymer material positioned in the through-holes, and a hard coating layer positioned on upper surfaces of the glass layer and the flexible polymer region, the hard coating layer having a higher elastic modulus than the transparent and elastic flexible polymer material.
