1. A flexible display device substrate comprising:
first flexible substrate;
a second flexible substrate disposed on the first flexible substrate; and
an interweaved structure layer disposed between the first flexible substrate and the second flexible substrate, wherein the interweaved structure layer is formed by a part of the first flexible substrate and a part of the second flexible substrate weaving and penetrating with each other,
a toughening layer, disposed at intervals between the first flexible substrate and the second flexible substrate, wherein the toughening layer is a layered structure,
wherein a portion of the toughening layer is embedded/sink into the first flexible substrate, the first flexible substrate surrounds a lower half of the toughening layer, and the second flexible substrate covers an upper half of the toughening layer,
a bonding strength between the first flexible substrate and the second flexible substrate in the interweaved structure layer is greater than 8.74N/cm, and
an optical transmissions of the first flexible substrate and the second flexible substrate are greater than 90%, a yellow indexes are less than 2, and a hazes are less than 1.
