AI Technical Summary
Technical Problem
The data routing of AMOLED display substrate is expensive to make, mainly due to the complex data routing structure, and it requires at least three metal film layers.
Method used
By providing a first metal layer and a second metal layer disposed insulated from each other on the substrate, the first metal layer includes a plurality of data traces, and the second metal layer includes a fan-out trace that is bent in the display area, and the data trace and fan-out trace are connected, and a fan-out trace is formed only in the second metal layer.
Benefits of technology
The film layer structure and production process of the wiring are simplified, and the production cost of the display substrate is reduced.

Abstract
The invention provides a display substrate and a display panel, and the display substrate comprises a substrate which comprises a display area; the first metal layer is arranged on the substrate, the first metal layer comprises a plurality of data wires, and the data wires are located in the display area; the second metal layer is arranged on the first metal layer, the first metal layer and the second metal layer are arranged in a mutually insulated mode, the second metal layer comprises a plurality of fan-out wires, and the fan-out wires are arranged in the display area in a bent mode. The first metal layer and the second metal layer which are insulated from each other are arranged on the substrate, the first metal layer comprises the data wires, the second metal layer comprises the fan-out wires which are bent in the display area, the data wires are connected with the fan-out wires, only the second metal layer is adopted in the display area to form the fan-out wires, and the data wires are connected with the fan-out wires. Therefore, the film layer structure of the wire can be simplified, the manufacturing process of the wire can be simplified, and the manufacturing cost of the display substrate can be reduced.
