摘要： Disclosed is a direct lighting type liquid crystal display device. A plurality of slide slots slightly larger than lamp holders are alternatively formed at both end portions of bottom chassis in the longitudinal direction concerning the bottom chassis, and lamp units are inserted into the bottom chassis. Flexible printed circuit (FPC) connecters are positioned at portions of the bottom chassis where the slide slots do not exist in order to connect the FPC connecters to control board when the FPC connecters are bent in the longitudinal direction concerning the bottom chassis. Therefore, the time for replacing a troubled lamp can be shortened and the workability for replacing the troubled lamp can be improved because the lamp unit can be drawn without separating the FPC connecters from the control board when the lamp unit including the troubled lamp is separated from the liquid crystal display device so as to replace the troubled lamp. Also, signal lines of the FPC connecters are not broken so that the reliability of the liquid crystal display device can be enhanced because the FPC connecters are not separated form the control board when the lamp unit is replaced.
