Abstract: A foldable display apparatus includes a display panel; a first plate under the display panel; and a support structure under the first plate and having a foldable area and two non-foldable areas respectively on both opposing sides of the foldable area. The support structure includes a first support plate having a plurality of opening patterns defined in the foldable area; a second support plate above the first support plate and including a material different from a material of the first support plate; and a first adhesive layer between the first support plate and the second support plate. The first adhesive layer has: first portions respectively in each of the non-foldable areas of the support structure; and a second portion in the foldable area of the support structure. The second portion has a higher degree of cure than a degree of cure of each of the first portions.
