Array substrate, manufacturing method thereof, and display

A display, comprising:

• an array substrate;
• a color filter substrate disposed oppositely to the array substrate;
• and
• a liquid crystal layer located between the array substrate and the color filter substrate,
• wherein the array substrate comprises a substrate body, the substrate body comprising a display area and a fan-out area, wherein
• signal lines are provided in the display area, at least two fan-out layers spaced apart in a thickness direction of the substrate body are provided in the fan-out area, and an insulating layer is positioned between two adjacent fan-out layers,
• a first fan-out line connected to the signal lines is provided in a fan-out layer away from the substrate body, and a second fan-out line connected to the signal lines is provided in a fan-out layer close to the substrate body,
• a first notch is provided on at least one of two sides in a width direction of the second fan-out line, wherein a portion of the insulation layer fills into the first notch in a direction towards the second fan-out line to form a recess part corresponding to the first notch, the recess part defining a groove, and
• a protruding part is provided on at least one of two sides in a width direction of the first fan-out line, wherein a portion of the protruding part fills into the groove in a direction towards the insulation layer to form a protrusion corresponding to the groove.
