A PCB (100) underneath the display panel (320) includes a plurality of insulation layers (111, 113, 115, 117, 119) and one or more metal layers disposed between two adjacent insulation layers out of the plurality of insulation layers (111, 113, 115, 117, 119). A lower structure (330) is disposed between the display panel (320) and the PCB (100). At least a portion of a metal layer among the one or more metal layers that is most adjacent to the lower structure (330) is exposed, and the lower structure (330) is electrically connected to the exposed portion of the metal layer (112). Such exposed portion of the metal layer (112) is electrically connected to the lower structure (330), so that the area where the PCB (100) is referenced to the ground potential is increased. As a result, residual voltage, residual current in the PCB (100) and noise caused by electromagnetic fields generated thereby can be reduced.
