Abstract: A backplate having a folding region and an unfolding region adjacent to the folding region includes: first and second material layers corresponding to the folding and unfolding regions; and a third material layer between the first and second material layers, the third material layer is more rigid than the first and second materials layers, wherein the first and second material layers extend from the folding region to the unfolding regions such that a thickness of the first and second material layers is gradually reduced from the folding region to the unfolding region.
