1. A flexible display substrate comprises a flexible substrate and is characterized in that insulating layers and metal layers are alternately arranged on the flexible substrate, the metal layers comprise metal line segments which are arranged in the same or similar extension direction in a separated mode, the metal line segments are provided with large end faces close to the flexible substrate and small end faces far away from the flexible substrate, inclined planes are formed at the head and the tail of each metal line segment, contact holes are formed in the insulating layers between adjacent metal layers, the metal line segments of the adjacent metal layers are alternately connected through metal in the contact holes to form continuous metal leads, and the sections of the metal line segments in the extension direction of the metal leads are trapezoidal;

  • the adjacent metal layers include a first metal layer and a second metal layer, the first metal layer being proximate to the flexible substrate relative to the second metal layer, wherein a number of metal line segments of the first metal layer is greater than a number of metal line segments of the second metal layer.
