Abstract
A flexible display device may include a display module including a first non-bending area and a first bending area adjacent to the first non-bending area, and a cushion layer disposed on a rear surface of the display module, wherein the cushion layer has a first density in the first non-bending area and a second density in the first bending area, and the first density is lower than the second density.
Claims20
A flexible display device, comprising:
- a display module including a first non-bending area and a first bending area adjacent to the first non-bending area;
- and
- a cushion layer disposed on a rear surface of the display module,
- wherein the cushion layer has a first cushion layer having a first density in the first non-bending area and a second cushion layer having a second density in the first bending area, and the first density is lower than the second density in an unfolded state prior to bending the first bending area, and
- wherein the first cushion layer and the second cushion layer are disposed in a same layer and have a uniform thickness.
