Zusammenfassung:	PROBLEM TO BE SOLVED: To provide structure of distortion reinforcement and to provide structure for suppressing projection of a rivet, etc. for fixing a backlight substrate by changing the shape of the backlight chassis.SOLUTION: On the chassis rear surface 34 of a backlight chassis 30, recesses 36 are formed at 14 stages, and over the entire chassis rear surface 34 as the horizontally extending rugged shapes. Length of the recesses 36 becomes slightly shorter than width of the backlight chassis 30. Inside the backlight chassis 30, an LED substrate unit 24 is attached to the recess bottom surface 37. A plurality of LEDs 28 are serially connected to the LED substrate unit 24.
