FLEXIBLE DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME
First Claim
1. A flexible display device comprising:
- a substrate defined by a display area and a non-display area being an outer region of the display area and including a link area and a pad area, the substrate being formed of a flexible material;
a plurality of gate lines and a plurality of data lines formed in the display area on the substrate, such that the gate lines and the data lines cross each other to define a plurality of pixel areas in the display area;
a plurality of pads formed in the pad area, each pad being connected to an exterior circuit to supply a driving signal to a signal line selected from signal lines including the gate line or/and the data line;
a plurality of links formed in the link area, the links connecting the respective pads and the signal lines;
a plurality of insulation films formed over the surface of the substrate, the insulation films insulating conductive layers from one another; and
a first bending hole formed in a bending area of the non-display area, the first bending hole passing through at least one of the insulation films formed between the link and the substrate, wherein the bending area is bent such that the pads are disposed on the back side of the surface of the substrate.

12. A method for manufacturing a flexible display device, comprising:
-
forming a substrate defined by a display area and a non-display area being an outer region of the display area and including a link area and a pad area, using a flexible material; forming a buffer film over the surface of the substrate; forming a gate insulation film over the surface of the buffer film; forming gate lines in the display area on the gate insulation film; forming an interlayer insulation film over the entire surface of the gate insulation film such that the interlayer insulation film covers the gate lines; forming a first bending hole passing through at least the gate insulation film and the interlayer insulation film in a bending area, wherein the bending area bends such that the pad area of the non-display area is disposed on the lower surface of the substrate; forming data lines and a plurality of links, wherein the data lines are formed in the display area on the interlayer insulation film such that the data lines cross the gate lines, and wherein the plurality of links are connected to signal lines selected from the gate lines and the data lines in the linking area on the interlayer insulation film; forming a protective film over the surface of the interlayer insulation film such that the protective film covers the data lines and the links; forming a plurality of pads connected to the links and connected to an exterior circuit to supply a driving signal to the signal line on the protective film; and bending the bending area such that the pads are disposed on the back side of the surface of the substrate. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
