Abstract
A flexible display device and an electronic device including the same are disclosed. The flexible display device includes a magnetic body group, which is adhered to a lower plate provided under a display panel by the force of magnetic attraction. Therefore, the flexible display device has improved reliability in spite of frequent folding and unfolding operations and is capable of facilitating a rework process.
Claims18
A flexible display device, comprising:
- a display panel;
- a lower plate formed of stainless steel, a first surface of the lower plate facing a bottom surface of the display panel, the lower plate including a folding region and a non-folding region adjacent to the folding region, the folding region having a density lower than a density of the non-folding region;
- a group of magnetic bodies including a first magnetic body attached to the folding region and a second magnetic body attached to the non-folding region, the magnetic body group contacting with a second surface of the lower plate that is opposite to the first surface;
- and
- a metal film provided on the second surface of the lower plate that faces the magnetic body group, the metal film being brought into direct contact with a magnetic body of the magnetic body group.
