However, in such a conventional liquid crystal display module, in order to mount the circuit board 9 on the rear surface of the holder 1, the two engaging recessed portions 10 of the circuit board 9 are attached to the holder 1. Since only the two substantially L-shaped engaging projections 3 are engaged with each other, the circuit board 9 can be prevented from moving rearward, upward, and leftward and rightward, but it cannot prevent downward movement. Therefore, there is a problem that the circuit board 9 may move downward and the engaging recess 10 may be disengaged from the substantially L-shaped engaging projection 3 of the holder 1. It is conceivable to use a fixing screw or the like, but in this case, there is another problem that the number of parts is increased and the disassembling work at the time of assembly work and repair is troublesome. An object of the present invention is to provide a liquid crystal display module that can mount a circuit board on the rear surface of a holder while preventing movement in all directions without using fixing screws or the like.
