1. A display panel, comprising:
a substrate comprising a display region and a non-display region adjacent to the display region; a thin film transistor disposed on the non-display region of the substrate, wherein the thin film transistor comprises:
a semiconductor layer disposed over the substrate;a first insulating layer disposed over the semiconductor layer;a first metal layer disposed over the first insulating layer;a second insulating layer disposed over the first insulating layer;a first via hole series and a second via hole series disposed adjacent to respective opposite sides of the first metal layer, wherein the first via hole series comprises a plurality of first via holes, and the second via hole series comprises a plurality of second via holes, wherein the plurality of first via holes and the plurality of second via holes are defined by a sidewall of the first insulating layer, a sidewall of the second insulating layer, and a surface of the semiconductor layer;a second metal layer disposed over the second insulating layer, wherein the second metal layer comprises a first portion and a second portion, wherein the first portion electrically connects the semiconductor layer through the plurality of first via holes, and the second portion electrically connects the semiconductor layer through the plurality of second via holes,wherein a minimum distance between an edge of the first portion and an edge of the first metal layer is a first distance, and a minimum distance between an edge of the second portion and another edge of the first metal layer is a second distance, and the second distance is greater than the first distance. |
