摘要： A foldable display is disclosed. In one aspect, the foldable display includes a display panel including: a plurality of flat regions and a folding region interposed between the flat regions. Each of the flat regions includes a fixed region and a semi-fixed region interposed between the fixed region and the folding region. The foldable display also includes a plurality of substrates respectively attached to the flat regions and a plurality of fixed adhesive members respectively interposed between the fixed regions and the substrates. The fixed adhesive members respectively attach the substrates to the fixed regions. The foldable display further includes a plurality of semi-fixed adhesive members respectively interposed between the semi-fixed regions and the substrates. The semi-fixed adhesive members are configured to respectively attach/detach the semi-fixed adhesive regions to/from the substrates based on the degree to which the display panel is folded.
