PROBLEM TO BE SOLVED: To prevent unnecessary light emission when powered-ON with simple constitution. SOLUTION: When a power-OFF signal is input, an OSD circuit 14 is commanded to output OSD data for displaying a black picture continuously for, for example, one second in step S110. The image data for displaying the black picture are output and unnecessary light emission when powered-ON can be prevented. It is only required for a driver 12 to perform the same display cycles as usual. COPYRIGHT: (C)2008,JPO&INPIT
