A backlight device 24 includes an LED unit 32, a light guide plate 20 having a light entrance surface 20a on its side surface, and a backlight chassis 22 including a bottom plate 22a and housing the LED unit 32 and the light guide plate 20 on a front surface of the bottom plate. The LED unit 32 is arranged to face the light entrance surface 20a of the light guide plate 20. The backlight chassis 22 includes a positioning pin 40 on its front surface of the bottom plate 22a. The positioning pin 40 is projected from the front surface. The light guide plate 20 has a recessed fitting portion 38 corresponding to the positioning pin 40, and the positioning pin 40 is fitted to the fitting portion 38. A through hole 40a is formed in peripheral surface of the positioning pin 40 so as to be through the positioning pin 40.</p> |
