Abstract

A chip-on-film package includes a base substrate on which a first pad region, a second pad region, and a third region located between the first pad region and the second pad region are defined, a dummy pad disposed on the first pad region, input pads disposed on the first pad region, output pads disposed on the second region, a first detection line disposed on the base substrate, and a second detection line disposed on the base substrate. The first detection line is connected to a first input pad and a second input pad via the second pad region to form a first loop between the first input pad and the second input pad, and the second detection line is connected to the dummy pad and the first detection line via the third region to form a second loop between the dummy pad and the first input pad.
