Element array substrate

The invention discloses an element array substrate. The element array substrate comprises a flexible substrate, a plurality of wiring units and a plurality of sub-pixel units, the flexible substrate comprises an island part and a plurality of connecting parts. The island portion has a central structure and a plurality of peripheral structures, the peripheral structures are connected to side surfaces of the central structure, and the central structure is rectangular. The connecting parts are respectively connected with the central structure through the surrounding structures, and at least one side of each connecting part is arc-shaped. The wiring units are arranged on the connecting parts. The sub-pixel units are arranged on the island part and are electrically connected with one of the wiring units. The sub-pixel units comprise first sub-pixel units, the first sub-pixel units are located on the central structure and closest to the side face of the central structure, and the maximum distance between the first
