When the printed circuit board 8 is soldered in a solder bath and the printed circuit board 8 has a warp due to thermal deformation, and the slit 3 of the case 1 of the LED unit 9 cannot absorb the warp, the case 1 moves in the longitudinal direction of the case 1. The claw 4 on one side surface is lifted, and a gap or inclination is generated between the LED unit 9 and the printed circuit board 8. Then, when the display device is assembled as shown in FIG.
And the display sheet 6 or the inner wall of the display panel 7 come into contact with each other, stress is applied to the terminal soldering portion of the LED 2, and the copper foil used for wiring is floated. In addition, the positional relationship between the LED unit 9 and the display sheet 6 may be displaced and the LE
The visibility of the light emitting portion of D2 becomes poor. To prevent it
As shown in FIG. 8, after the LED unit 9 is inserted into the printed circuit board 8, the leads 10 of the LEDs 2 are manually bent and formed.
