PURPOSE:To make work such as layout pattern check, addition and delete or the like efficient by providing the device with means generating a 3-dimensional structure image of the entire multilayer printed circuit board and displaying a stereoscopic picture. CONSTITUTION:This device is provided with a 3-dimensional picture generating section 24 used to express a wiring structure comprising several layers in a 3-dimensional way, a right eye picture memory 23 and a left eye picture memory 22 setting visual point and visual line direction for the right eye and the left eye respectively and storing a right eye picture and a left eye picture generated by the 3-dimension picture generating section 24, a stereoscopic picture control section 25 transferring the stored content in the right and left eye memories alternately to a frame memory 13 and outputting a switching signal 27 showing that the right eye and the left eye are switched, and a stereoscopic visual eyeglass 26. The stereoscopic visual eyeglass 26 covers the left or the right eye alternately by the switching signal outputted from the stereoscopic picture control section 25. In this case, a liquid crystal shutter is used to cover the left/right eyes. |
