Abstract
The present application provides a chip on film and a display device, the chip on film including a plurality of first source signal lines located at a middle, and a plurality of second source signal lines located at opposite sides, wherein each of the first source signal lines has a cross-sectional area smaller than a cross-sectional area of each of the second source signal lines in a reference plane. Based on the structure, attenuation from the source driver chip to each data lines is substantially the same or even completely the same.

A chip on film, comprising:
- a substrate;
- source driving chips disposed on the substrate and comprising source driving terminals;
- source connection terminals disposed in a one-to-one correspondence with the source driving terminals;
- and
- source signal lines connecting the source connection terminals and the source driving terminals,
- wherein the source signal lines comprise a plurality of first source signal lines located at a middle, and a plurality of second source signal lines located at opposite sides, wherein each of the first source signal lines has a cross-sectional area smaller than a cross-sectional area of each of the second source signal lines in a reference plane, and the reference plane is perpendicular to the substrate and parallel to an arrangement direction of the source connection terminals.
