Description of the Related Art A peep window built into a door of a conventional house or storage is composed of a lens or a plate glass, and the situation on the other side of the door can be seen through the peep window. . In the case of the viewing window using the above lens, the other side of the door can be seen through with a wide field of view, despite the smaller opening portion due to the action of the lens. But,
This conventional peep window does not have the function of arbitrarily changing the transparent part to opaque, and if you want to prevent see-through from the other side of the door, you must attach a curtain or other shield to the peep window part of the door. There was a problem.

る。FIG. 1 is a perspective view showing a usage example of the present invention. As shown in FIG. 1, the sight glass 2 of the present invention is incorporated in a door 1 and is connected to an electric circuit 4 having a switch 3. FIG. 2 schematically shows the cross section of the observation window 2. In FIG. 2, the observation window 2 is composed of a liquid crystal light control device 5 and a flat lens 6. This liquid crystal light control device 5 is configured by disposing a transparent conductive film 8 on both surfaces of a composite film 7 of a transparent resin and a liquid crystal substance, and disposing a transparent substrate 9 such as a glass or a plastic film. Has a property of becoming transparent when a voltage is applied and becoming opaque when a voltage is not applied. Further, the material of the plate-shaped lens 6 used together with the liquid crystal light control device 5 is not particularly limited, but it is preferable to use a plastic Fresnel lens.
