PROBLEM TO BE SOLVED: To reliably eliminate an error in attachment of a light source substrate to a supporting plate by visually and tactually performing double checking, when one or a plurality of kinds of light source substrates are attached to the supporting plate, which one or the plurality of kinds of light source substrates of the plurality of kinds of light source substrates whose kinds are different according to the number of attached light emitting components are to be attached to.SOLUTION: Substrate holes 30a and 30b, substrate holes 30c and 30d and substrate holes 30e and 30f are formed in an LED substrate 30A for five on which five LEDs are provided, an LED substrate 30B for six on which six LEDs are provided, and an LED substrate 30C for eight on which eight LEDs are provided, respectively, and a plurality of chassis holes 40a to 40f for fitting the plurality of substrate holes 30a to 30f are formed in prescribed portions mating each of the plurality of substrate holes 30a to 30f in a chassis 40. |
