PROBLEM TO BE SOLVED: To make burning of a screen inconspicuous in displaying ordinary picture by discriminating the conditions of a picture to be displayed, choosing either the first or the second display means for the display depending on the result of the discrimination, and thereby dividing between a fixed picture that causes burning and other ordinary picture by means of an odd number/even number line display. SOLUTION: A discriminating means 310 discriminates the conditions of a picture to be displayed and causes a selector means 320 to select, depending on the result of the discrimination, the emission by odd number lines only (with even number lines turned off) or by even number lines only (with odd number lines turned off). To be concrete, if the picture to be displayed is a fixed picture (e.g. initial operation picture before the start of a prescribed operation), it is displayed as a picture on the odd number lines for example. If it is a picture other than the fixed picture (plural pictures specified by the initial operation picture), it is displayed as a picture on the even number lines.
