Underlay substrate 15；
Form a plurality of signal transmssion line 16 on underlay substrate 15, signal transmssion line 16 be used for by drive signal transmit to
Viewing area 11；
At least one virtual signal transmission line 17 and first floating connecting line 18 of the formation on underlay substrate 15, first
Floating connecting line 18 and signal transmssion line 16 and the insulation set of virtual signal transmission line 17, the first dd connecting lines are used to pass in signal
When defeated line 16 is broken, signal transmssion line 16 and virtual signal transmission line 17 are connected respectively.
Exemplary, in 16 normal work of signal transmssion line, the first floating connecting line 18 and signal transmssion line 16 and void
Intend signal transmssion line 17 and distinguish insulation set, drive signal can individually be transmitted to viewing area 11, ensured by signal transmssion line 16
Flexible display substrates normally show, normal work.But as shown in figure 1, signal transmssion line 16 is included positioned at the portion of bent area 13
Point, signal transmssion line 16 is easily broken in bent area 13, such as the W area shown in figure.When signal transmssion line 16 occurs
During fracture, drive signal can not be transmitted to viewing area 11 separately through signal transmssion line 16, cause flexible display substrates can not be just
Often display, normal work.In the embodiment of the present invention, by setting up 17 and first floating connecting line 18 of virtual signal transmission line, the
Upright projection of the one floating connecting line 18 on underlay substrate 15 exists with signal transmssion line 16 and virtual signal transmission line 17 respectively
Be present overlapping region in the upright projection on underlay substrate 15, in this way, when signal transmssion line 16 is broken in bent area 13, lead to
Cross the first floating connecting line 18 to electrically connect with signal transmssion line 16 and virtual signal transmission line 17 respectively, skip the letter being broken
Number transmission line 16, drive signal is transmitted to viewing area 11 by virtual signal transmission line 17 and signal transmssion line 16, ensured
Flexible display substrates normally show, normal work.It should be noted that Fig. 1 is exemplarily only depicted positioned at viewing area 11
A part for signal transmssion line 16, without drawing the signal transmssion line positioned at viewing area 11 completely.
Optionally, can be by way of laser welding by when signal transmssion line 16 is broken in bent area 13
One floating connecting line 18 electrically connects with signal transmssion line 16 and virtual signal transmission line 17.
Specifically, with continued reference to Fig. 1, signal transmssion line 16 can include the end 162 of first end 161 and second, first end 161

Intend 17 and first floating connecting line 18 of signal transmssion line, virtual signal transmission line 17 directly electrically connects with driver element 19, drives
Signal passes sequentially through virtual signal transmission line 17, the first floating connecting line 18 and signal transmssion line 16, by drive signal transmit to
Viewing area 11, the position for the signal transmssion line 16 being broken is skipped, ensure that flexible display substrates can normally be shown, normal work
Make, lift the production yield of flexible display substrates.
Optionally, flexible display substrates provided in an embodiment of the present invention, driver element 19 can include multiple first signals
Interface 191 and multiple secondary signal interfaces 192, a plurality of signal transmssion line 16 and a plurality of virtual signal transmission line 17, the first signal
The quantity of interface 191 can be identical with the quantity of signal transmssion line 16, and the quantity of secondary signal interface 192 can be with virtual signal
The quantity of transmission line 17 is identical, and each first signaling interface 191 electrically connects with being corresponded per bars transmission line 16, Mei Ge
Binary signal interface 192 is corresponded with every virtual signal transmission line 17 and electrically connected, while multiple signals to being broken pass
Defeated line 16 is repaired, and ensures that flexible display substrates are normally shown.It should be noted that Fig. 1 is only with a bars transmission line 16
It is broken, is said exemplified by only being repaired by a virtual signal transmission line 17 to the signal transmssion line 16 being broken
It is bright.
