PROBLEM TO BE SOLVED: To provide an edge light type backlight capable of supporting a light guide plate so that the light guide plate does not come into contact with an LED and preventing deterioration of luminance and luminance uniformity. Providing equipment. A backlight device 10 includes a backlight chassis 1, a light guide plate 5, a plurality of LEDs 6, light source substrates 2a to 2f, and a regulating member 4. In the light source substrates 2a to 2f, a plurality of LEDs 6 are mounted on the surface, and a first through hole 12 penetrating in the thickness direction is formed in at least one of the gap portions between the adjacent LEDs 6. The regulating member 4 regulates the movement of the light guide plate 5 in the surface direction, and is connected to the shaft portion 7b inserted into the first through hole 12 and one end portion in the axial direction of the shaft portion 7b. And a fitting portion 8 fitted to the other axial end of the shaft portion 7b. [Selection] Figure 1 |
