Flexible Organic Light Emitting Diode Display Device

摘要

Embodiments relate to a flexible organic light emitting diode (OLED) display device and a method for manufacturing the flexible OLED display device. The display device includes a multi-layered encapsulation film coving pixel regions of the display device, and a metal layer on or within at least a portion of the encapsulation film, the portion in a bending region of the flexible substrate. The multi-layered encapsulation film includes at least a first inorganic layer, an organic layer, and a second inorganic layer. The metal layer is formed in the bending region such that the stress generated in the encapsulation film by folding, bending, or rolling operations in the bending region is reduced by the metal layer. The metal layer prevents generation of cracks in the encapsulation film and thus, prevents moisture penetration into the display area of the display device.
