7 . A backlight unit comprising:
a LED-mounted board having light-emitting diodes (hereinafter, referred to as LEDs) as a backlight source;
a light guide plate to which the LEDs are disposed to face, and which has a light receiving surface to which light from the LEDs incidents and an emission surface from which the incident light is output; and
a frame which holds the LED-mounted board and the light guide plate, and which has an attaching/detaching slot of the LED-mounted board,
wherein the LED-mounted board has an engaging section that engages between the frame and the LED-mounted board each other being formed in the backlight unit held removably in the frame.
8 . The backlight unit according to claim 7 ,
wherein the engaging section includes a hole formed on the LED-mounted board and a protrusion formed in the frame.
9 . The backlight unit according to claim 8 ,
wherein the LED-mounted board comprising:
a flexible printed wiring board that is mounted by the LEDs; and
a metallic reinforcing plate that is attached with the flexible printed wiring board,
wherein the reinforcing plate forms the hole.
10 . The backlight unit according to claim 8 ,
wherein the frame forms a pressing section that elastically deforms extending from the frame, and the protrusion is formed so as to project from the pressing section.
11 . The backlight unit according to claim 10 ,
wherein the protrusion has a sloping side surface, and
the pressing section is to be elastically deformed by sliding the LED-mounted board on the sloping side surface of the protrusion when the LED-mounted board is attached or removed.
12 . The backlight unit according to claim 7 ,
wherein the LED-mounted board is mounted with a plurality of LEDs, and
the engaging section is formed between the LEDs adjacent to each other.
