PRINTED CIRCUIT BOARD AND DISPLAY DEVICE HAVING THE SAME

摘要

A circuit board is provided. An objective of the present invention is to provide a printed circuit board which suppresses electrostatic discharge (ESD) and electromagnetic interference (EMI) to prevent malfunction. The circuit board comprises: a plurality of lines which extend along a first direction and are arranged to be parallel with one another along a second direction which is perpendicular to the first direction; a plurality of pads which have a predetermined length extending along the first direction and are arranged on the lines; and a ground pad which is arranged outside the pads. The lines include first lines for delivering a positive polarity signal and second lines for delivering a negative polarity signal. The pads include first pads arranged on the first lines and second pads arranged on the second lines. A cross-sectional area of each of the lines is substantially identical to a cross-sectional area of each of the pads.
