PROBLEM TO BE SOLVED: To provide a ROM inspection system or the like, capable of shortening inspection time of image ROM in a mounted stage. SOLUTION: A display device 300 comprises a CPU 301, a CGROM 306, and a VDP 304 which has an accessible area 308 accessible by the CPU 301 and is accessible to the CGROM 306. The CPU 301 is configured to output data read control information for each address corresponding to each address signal line of the CGROM 406 to the VDP 304, and to perform inspection based on data of each address written to the accessible area 308 by the VDP 304.
