To provide an animation image evaluation set for a liquid crystal display device, the set which is made easily lightweight.
A power source circuit 29 is mounted on a data transform circuit board 27 of a PC card 26 connected to a signal source 24. The electric power necessary for lighting each of light emitting diodes of a liquid crystal module 22 is supplied by the power source circuit 29 from the signal source 24 through the PC card 26 to an LED lighting circuit board 51. The need for an external power source having a relatively heavy weight, such as an AD/DC converter circuit for supplying the electric power for lighting each of the light emitting diodes of the liquid crystal module 22 to the LED lighting circuit board 51 from the outside is eliminated. The animation image evaluation set 21, therefore, is made lighter in weight, and the portability is greatly improved.
