Flexible substrate and display device

A flexible substrate, comprising a flexible base substrate, and a wiring bonding structure disposed on the flexible substrate and comprising at least two rows of bonding wirings, wherein a filler is arranged between two adjacent rows of bonding wirings;

• wherein each row of bonding wirings comprises a plurality of bonding leads, the filler is further arranged between the plurality of bonding leads, the bonding leads are formed by a conductive layer on the flexible base substrate, and the filler is formed by a polyimide film at a same layer as the conductive layer;
• the wiring bonding structure further comprises at least two groups of dummy wirings distributed on opposite ends of the at least two rows of bonding wirings in the first direction and arranged at a same side of the flexible substrate, where the first direction is a row direction of each row of bonding wirings, the filler is further arranged between each group of dummy wirings and the at least two rows of bonding wirings, each group of dummy wirings comprises a plurality of dummy leads, the filler is further arranged between the plurality of dummy leads, an extension direction of each dummy lead is a second direction intersecting the first direction at an angle, each dummy lead is arranged in such a manner as to directly face a gap between two adjacent rows of bonding wirings in the at least two rows of bonding wirings, and a length of each dummy lead in the second direction is greater than or equal to a width of a gap between two adjacent rows of bonding wirings in the second direction.
