To provide a light control window for a vehicle that can project a picture clearly, and a light control window system for a vehicle.SOLUTION: A light control window 1 for a vehicle includes a transparent board 3, a first conductive film 5, a light control layer 7, a second conductive film 9, and a projection film 11 in that order. The light control window 1 for a vehicle emits a picture light L to a projection film 11 arranged before the light control layer 7 under the condition that the light control layer 7 behind the projection film 11 is made opaque. It thus becomes possible to display a clear picture. Since the light control layer 7 is opaque, a passenger who is watching a picture cannot be easily seen from the outside, which is desirable in terms of privacy.SELECTED DRAWING: Figure 1
【課題】映像を鮮明に投影可能な乗物用調光ウィンドウ、及び乗物用調光ウィンドウシステムを提供する。【解決手段】乗物用調光ウィンドウ1は、透明板3と、第1導電膜5と、調光層7と、第2導電膜9と、投影用フィルム11と、をこの順に配してなる。乗物用調光ウィンドウ1では、投影用フィルム11の背後の調光層7を不透明状態として、調光層7の手前に配された投影用フィルム11に映像光Lを出射する。これにより、映像を鮮明に表示できる。調光層7が不透明状態となるから、乗員が映像を見ている間、乗物外からその様子が見えにくく、プライバシー性の観点から好ましい。【選択図】図1
