1. A display device comprising:
a first metal layer disposed on a substrate;
a first insulating layer disposed on the first metal layer;
a first transistor disposed on the first insulating layer, the first transistor including a semiconductor layer; and
a light-emitting device electrically connected to the first transistor,
wherein the first metal layer includes:
a first portion overlapped with the semiconductor layer in a plan view and having a first thickness, and
a second portion not overlapped with the semiconductor layer in the plan view and having a first region having the first thickness and a second region having a second thickness thicker than the first thickness, the first region protruding from an edge of the second region in a direction away from the second region, and
wherein the semiconductor layer is electrically connected to the first metal layer and the first region and the second region comprise a same material.
