摘要： A printed circuit board is provided to reduce an error rate and satisfy an impedance range of a TMDS(Transition Minimized Differential Signaling) transmission line as an HDMI(High Definition Multimedia Interface) standard. A printed circuit board(100) includes a plurality of signal layers(140), a ground layer(120), a power layer(130), and an element. The plurality of signal layers include transmission lines(110). The ground layer and the power layer are interposed between the plurality of signals. The element increases capacitance on the transmission lines. A region of the ground layer on a lower part of the element is removed. The removed region of the ground layer is in proportion to a size of the element. The element includes an ESD(ElectroStatic Discharge) preventing element(160) and is connected to the ground layer through a via(170).
