Abstract
A chip-on-film includes a flexible substrate, a plurality of negative polarity pins, and a positive polarity pin. The plurality of negative polarity pins are arranged in a row in a first direction on the flexible substrate, and two adjacent negative polarity pins of the plurality of negative polarity pins are arranged in an interval. The positive polarity pin is disposed on the flexible substrate. The positive polarity pin is at least partially located between two adjacent negative polarity pins of the plurality of negative polarity pins. The positive polarity pin includes a first extension portion and a second extension portion. The first extension portion intersects the second extension portion.
