Abstract
The purpose of the invention is to realize the flexible display device of high reliability; specifically in a structure that a bending area is in a terminal area, and in that disconnection of the wiring does not occur in the bending area. The concrete structure is that: a display device having a display area, a driving circuit area and a bending area comprising: a first thin film transistor and a first interlayer insulating film are formed in the display area, a second thin film transistor and a second interlayer insulating film are formed in the driving circuit area, terminal wirings to connects the display area and the driving circuit area are formed in the bending area.
