PURPOSE: A PCB having a direct interface structure and an LCD using the same are provided to reduce a height which a part is mounted to a printed circuit board. CONSTITUTION: A PCB(10) having a direct interface structure is that an internal specific insulating layer is extended in the horizontal direction and disclosed to form a pa rent body among insulating layers consisting of a multi-layer structure and that each face of the disclosed part is patterned and interfaced with the internal pattern of the insulating layer to form a main connecting part(14). In an LCD including the PCB, a connector to which a concave connecting part(16) is formed is connected to the main connecting part of the printed circuit board. the concave connector is consisted of connecting pins up and down in space between the insulating layers. A convex connector is provided between the connecting pins and, electrically, connected.
