A PCB structure related to an LCD connection part of a mobile terminal is provided to provide enhance the reliability and quality of a mobile terminal by performing a stable operation against an external abrupt situation, effectively use a PCB region, and reduce a unit cost by reducing the size of an ESD(Electrostatic Discharge) protection unit. A ground region(24) is additionally allocated in place of the certain number of ESD protection units connected with an LCD connection unit(21) in order to protect against ESD power. A plurality of ground holes(23) additionally connect the ground region(24) to a ground region of a different PCB layer. A PCB inner layer is formed such that an LCD signal line connected to an LCD connection unit is positioned at one region and a side region of the LCD signal line is allocated as a ground region. A PCB upper layer or a PCB lower layer is formed such that an upper or a lower portion of the PCB inner layer is additionally allocated as the ground region in place of the certain number of ESD protection units connected to the LCD connection unit, and a plurality of ground holes additionally connect the ground region to the ground region of the PCB inner layer.
