ABSTRACT:
A printed circuit board comprises a plurality of board layers and a plurality of wiring layers both of which are laminated. When a wiring pattern is disposed at one side against the center line, a dummy wiring pattern is formed at the place substantially symmetrical to the position where the wiring pattern is disposed to suppress a warp of the printed circuit board caused by temperature changes and to ease connection work between the printed circuit board and units, such as TABs for driving liquid crystal.
