<p>PROBLEM TO BE SOLVED: To provide an image display device capable of making the display of a rear side unwanted window into non-display or easily switching the display/ non-display of a front side temporarily wanted window on a picture overlapping plural windows. SOLUTION: When a front clip face 1008 is set at a position 1008a as an image visible through a grid 1010, one part of a window 1005 behind it can be watched but since the window 1005 is located in front of the front clip face 1008 when the front clip face 1008 is set at a position 1008b, the window is too close to watch so that one part of the next window 1006 can be watched. As a result, only when reference is required for an operator, the window 1005 is displayed by operating a display range change button 50 and in the other case, the window 1005 can be made into non-display.</p> |
