Abstract
The present disclosure relates to a rollable display panel. The rollable display panel includes a first structure layer, a second structure layer, and a first adhesive layer stacked between the first structure layer and the second structure layer. The rollable display panel is divided into a rollable area, a strain accumulation area, and a flat area distributed in sequence along a rolling direction. A thickness of a part of the first adhesive layer located in the strain accumulation area is greater than a thickness of a part of the first adhesive layer located in the rollable area or the flat area.
