Flexible display device
View Patent ↗The present disclosure provides a flexible display device comprising a display area and a first sector area. The display area is provided with data signal lines therein. The first sector area adopts a wiring structure with double metal layers comprising a first metal layer and a second metal layer layered up and down. The data signal lines transmit a data signal through the first metal layer and the second metal layer in the first sector area. A first insulating layer and a second insulating layer are sequentially disposed between the first metal layer and the second metal layer, and the first metal layer and the second metal layer are partially longitudinally overlapped. The present disclosure provides a flexible display device capable of further reducing a width of its lower frame by reducing an effective width of its first sector area, thereby achieving a design of an ultra-narrow frame display device.
