The see-through window 3 can be brought into a see-through state by covering it to put it in a light-shielding state or by sliding it downward. Note that the same effect can be obtained even if the mask 4 is pulled out in the horizontal direction.
一第２実施例−
第２図に示す通り、２１は冷凍冷蔵庫であり、冷凍冷蔵
庫２１には、冷凍庫を蓋する冷凍庫用ドア２２と冷蔵庫
を蓋する冷蔵庫用ドア２３とが設けられている。冷凍庫
用ドア及び冷蔵庫用ドア２２．２３には、夫々全面に亘
って、液晶窓２４２５が嵌め込まれている。Second Embodiment - As shown in FIG. 2, 21 is a refrigerator-freezer, and the refrigerator-freezer 21 is provided with a freezer door 22 that covers the freezer and a refrigerator door 23 that covers the refrigerator. A liquid crystal window 2425 is fitted over the entire surface of each of the freezer door and refrigerator door 22,23.

である。In this embodiment, the liquid crystal window 24 of the freezer door 22 is controlled to have no voltage and is in a see-through state, and the refrigerator door 23
A predetermined voltage is applied to the liquid crystal window 25 to put it in a light-shielding state.
次に、第３図（ａ）、（ｂ）を参照して、液晶窓２４．
２５の動作原理を説明する。Next, referring to FIGS. 3(a) and 3(b), the liquid crystal window 24.
The operating principle of No. 25 will be explained.
液晶３１はネマチック液晶であり、２枚の透明電極板３
２．３３間に封入されている。透明電極板３３．３４は
２枚の偏向板３５．３６間に封入されている。The liquid crystal 31 is a nematic liquid crystal, and has two transparent electrode plates 3.
It is enclosed between 2.33 and 33. Transparent electrode plates 33, 34 are enclosed between two deflection plates 35, 36.
第２図（ａ）に示すように、無電圧時においては、透明

通した光を当ると、電極間で分子の方向が変わるのにと
もなって、偏向面が９０度回転して反対側の電極板３４
に出てくるため、偏向板３５と直角方向に置かれた偏向
板１１を通り抜けることができ、庫内に入射される。こ
のため、庫内に反射した光は、入ってきた経路を逆に辿
って偏向板３５を通り抜けるので、庫内を透視すること
ができる。As shown in FIG. 2(a), when no voltage is applied, the liquid crystal molecules in the portion that is in contact with the transparent electrode plates 33 and 34 are aligned parallel to the electrode plates, and the direction in which the molecules are aligned is perpendicular between the electrodes. It is twisted into a twisted state. When the light passes through the deflection plate 35, the direction of the molecules changes between the electrodes, and the deflection plane rotates 90 degrees so that the light passes through the electrode plate 34 on the opposite side.
Therefore, it can pass through the deflection plate 11 placed perpendicularly to the deflection plate 35 and enter the refrigerator. Therefore, the light reflected into the refrigerator passes through the deflection plate 35 by retracing its path of entry, so that the interior of the refrigerator can be seen through.
一方、第２図（ｂ）に示すように、電圧印加時において
は、透明電極板３２．３３間に電圧を印加すると、液晶
分子が電極板に垂直に立つように並び、偏向板３５を通
った光は、電場の方向が変わらずに偏向板３６に、到達
するため、これを通り抜けることできず、遮光状態にな
る。On the other hand, as shown in FIG. 2(b), when a voltage is applied between the transparent electrode plates 32 and 33, the liquid crystal molecules align perpendicularly to the electrode plates and pass through the deflection plate 35. Since the light reaches the deflection plate 36 without changing the direction of the electric field, it cannot pass through the deflection plate 36 and is in a light-shielded state.
−第３実施例−
なお、第１実施例における透視窓３において、その透視
窓３を構成する透明な樹脂材又はガラス材の屈折率を、
変えることにより、上述の実施例と同様の効果を得るこ

ができる。逆に直交する角度に近い場合は、入射するこ
とができるから、透視状態とすることができる。-Third Example- In addition, in the see-through window 3 in the first example, the refractive index of the transparent resin material or glass material that constitutes the see-through window 3 is as follows:
By changing, the same effect as in the above embodiment can be obtained.1 For example, if a material with a high refractive index is used,
If the viewing angle is shallow, the incident light will be reflected and a light-shielded state will occur, making it impossible for others to look into the viewing angle. On the other hand, if the angle is close to orthogonal, the light can be incident, and a see-through state can be achieved.
［発明の効果］
以上の説明の通り、本発明によれば、他人に干渉される
ことなく、箱体内に収納された物品等を透視するドア部
材を提供することができる。[Effects of the Invention] As described above, according to the present invention, it is possible to provide a door member through which articles etc. stored in a box can be seen through without being interfered with by others.
すなわち、本発明によれば、ドアを開閉することなく、
ワンタッチで、箱体内を透視することができ、しかも、
遮光状態とすることもできるから、他人に箱体内を覗か
