ABSTRACT:
A cover is introduced onto a holder, substantially perpendicular to the holder by guides which hold a liquid crystal display panel on the holder so that the liquid crystal display panel is displaceable only in a direction substantially perpendicular to the holder, then the cover is set on the holder with the liquid crystal display panel being interposed therebetween. The introducing end parts of stoppers projected from the cover are introduced into lock means provided to the holder so that convex parts formed by the introducing end parts are locked resiliently by the lock means. During assembly, the cover is moved only in a direction perpendicular to the display surface of the liquid crystal display panel with substantially no movement along the display surface thereof, thereby it is possible to prevent the display surface of the liquid crystal display panel from being damaged.
