Abstract:
The present disclosure provides a printed circuit board including a plurality of conductive layers separated by insulating medium and a plurality of connection structures. Each connection structure penetrates each of the conductive layers. The plurality of conductive layers comprises a first conductive layer in which first signal lines are located and a second conductive layer in which second signal lines are located, and the first and second signal lines are connected via the connection structures. Anti-pads surrounding the connection structures are provided on others of the plurality of conductive layers except the first and the second conductive layers. For a same connection structure, the anti-pads surrounding the connection structure include adjacent anti-pads and nonadjacent anti-pads. Size of the adjacent anti-pads in any direction parallel to the conductive layers is smaller than that of the nonadjacent anti-pads. The present disclosure also provides a display apparatus.
