## Abstract

A substrate and a display device are provided. The substrate includes a base and a signal line arranged on the base. The signal line includes at least two main film layers and a first additional film layer arranged between every two adjacent main film layers, wherein an electrical conductivity of the main film layer is larger than that of the first additional film layer; and a crystallinity of the main film layer is lower than that of the first additional film layer.

## Claims
