PRINTED CIRCUIT BOARD, DISPLAY APPARATUS HAVING A PRINTED CIRCUIT BOARD AND METHOD OF MANUFACTURING THE PRINTED CIRCUIT BOARD

摘要

A printed circuit board (“PCB”) includes a first pattern structure, a second pattern structure, a third pattern structure, and a fourth pattern structure. The first pattern structure includes a first ground pattern. The second pattern structure includes a first line pattern overlapping the first ground pattern and a second ground pattern electrically insulated from the first line pattern. The third pattern structure includes a third ground pattern overlapping the first line pattern and a second line pattern overlapping the second ground pattern. The fourth pattern structure includes a fourth ground pattern overlapping the second line pattern. Therefore, the PCB may decrease noise.
