[74]

On the other hand, as also shown in the 11b also 7 to flexible substrate (710) one aspect of (710a) (NA) services there is a drive integrated circuit connecting member (750) is connected to, cover layer (740) driver IC connecting member (750) covering one end thereof can.

[75]

The flexible substrate as aforementioned (710) the other side of (710b) is, display panel (730) disposed back plate corresponding to number 1 (760a) on, driving integrated circuit connecting member (750) displays and flexible substrate (710) the bending direction position when the number 1 is formed into a shape bent back plate (760a) to be located beneath the back plate number 2 (760b) can be a. Back plate vertically number 1 (760a) on back plate number 2 (760b) positioned between the support member (770) can be a.

[76]

7 Also shown in the flexible display device (700) is also 4a to 4c as reference number 1 and 2 also in bent back plate (760a) and back plate number 2 (760b), support member (770) but at least one of, the number one flexible substrate with various configurations not (710) the other side of (710a) can be one side support.

[77]

The aforementioned in the embodiment are, in flexible display device prevent up flexible substrate or wiring pad can be equal to or less than.

[78]

In addition to the aforementioned purpose in the embodiment, to prevent or minimize in flexible display device can be.
