It is an object of the present invention to provide a back-light device and a liquid crystal display whose manufacturing costs are low and wherein the light from light sources is guided to a light-guiding plate efficiently and the heat of the light sources is dissipated efficiently. The back-light device ( 12 ) of the liquid crystal panel ( 10 ) has a front frame ( 14 ) and a rear frame ( 26 ). There are provided four optical sheets ( 16 ), a light-guiding plate ( 18 ), a flexible PCB ( 20 ), two light sources ( 22 ), and a reflecting sheet ( 24 ) between the front frame ( 14 ) and the rear frame ( 26 ). The flexible PCB ( 20 ) has a PCB part ( 2002 ) and two erected parts ( 2003 ). A resistor ( 2008 ) and a thermistor ( 2010 ) as electronic parts, and two light sources ( 22 ) are installed on the PCB part ( 2002 ) in the vicinity of the erected parts ( 2003 ). A light-radiating surface ( 2202 ) of the light source ( 22 ) is pressed to an incident surface ( 1802 ) of the light-guiding plate ( 18 ) by the erected part ( 2003 ).
