Abstract

[PROBLEMS] To prevent mistake of fitting position and fitting direction of each substrate when a plurality of substrates is fitted in a base member. [MEANS FOR SOLVING PROBLEMS]

Backlight unit X in a LCD device comprises such as a plurality of LED substrates 10 respectively mounting a plurality of LED elements 11 for illuminating each division multi-divided from the entire area of a LCD panel, and Chassis 1 as a base member in which LED substrates 10 are aligned and fitted, wherein Fitting position distinguishing mark 12 indicating a designed (qualified) fitting position of a relevant LED substrate 10 in Chassis 1 is recorded on each of a plurality of LED substrates 10. Fitting position distinguishing mark 12 is the mark graphically displaying the area to be covered by a relevant LED substrate 10 in the entire Chassis 1 when the LED substrate 10 is fitted in Chassis 1 as designed. And on every LED substrate adjusted in a designed fitting direction relative to Chassis 1, Fitting position distinguishing mark 12 is recorded in an area which is nearly the same area but other than the center nor vicinity thereof in LED substrate 10.
