Flexible display device

A flexible display device, comprising:

• a substrate including a display area and a non-display area, the display area having an optical area and a main area and the non-display area having a bending area and a non-bending area;
• a first insulating film disposed on the substrate;
• a wiring line disposed on the first insulating film of the non-bending area;
• a second insulating film disposed on the wiring line;
• a connection line disposed on the second insulating film of the non-bending area and having a first contact area connected to the wiring line;
• a first planarization layer disposed on the connection line;
• a link line disposed on the first planarization layer to extend to the bending area and having a second contact area connected to the connection line;
• a second planarization layer disposed on the link line and including an open area formed by removing a partial area to expose the second contact area of the link line;
• and
• a third insulating film disposed on the second planarization layer and filled in the open area.
