Abstract

A substrate, a display panel and a display apparatus are provided. The substrate is provided with a fan-out area. The fan-out area includes a middle region and side regions. The middle region has first metal wires arranged therein. The side regions have second metal wires arranged thereon. Lengths of the second metal wires in the side regions are greater than lengths of the first metal wires in the middle region, and impedances of the first metal wires in the middle region are higher than impedances of the second metal wires in the side regions.
