PURPOSE: To see through an image without recognizing the image by obtaining an opaque sheet equipped with a seeing-through function using holes as seeing- through elements and an opaque dot image equipped with a seeing-through function using holes as seeing-through elements.

CONSTITUTION: The opaque sheet 1 can display the image 2 and can be bored for the seeing-through elements 3, and the image 2 neither oozes nor is embossed on the reverse surface of the opaque sheet 1. The sheet is made of an opaque material or sheet in an opaque state which can erase the oozing and embossing to prevent the trouble of the image, and seeing-through elements 3 are fine. For example, when this is stuck on the rear windshield of a vehicle with the image out, the driver can see through an outside scene through the rear windshield without recognizing the image, and the drivers of following vehicles can recognize the image clearly. Consequently, when the outside scene on the image display side is seen through from the reverse side of the image display, the outside scene can be seen through without recognizing the image.
