Abstract: A chip on film includes: a flexible substrate; and a multilayer wiring structure disposed on the flexible substrate. The multilayer wiring structure includes a first wiring layer, a first insulation layer and a second wiring layer, which are sequentially arranged in a direction towards the flexible substrate the flexible substrate. The first wiring layer includes a first conductive material and the second wiring layer includes a second conductive material. The chip on film further includes: pins, at least part of which are in the first wiring layer; first via holes in the first insulation layer; and a second wire and a second wire leading portion in the second wiring layer, which are electrically connected to each other. More than one pin is electrically connected to the second wire leading portion through more than one first via hole, respectively.
