Thus, when the movable plate 40 is set to the translucent position, light incident from one side in the panel thickness direction is one polarizing layer 38, one pattern retardation layer 39, the other pattern retardation layer 44, and the other polarization. The layer 43 is transmitted while being linearly polarized or circularly polarized. That is, a bright state is obtained on the other side in the panel thickness direction.

  If the movable plate 40 is arranged so that the phase difference regions 39a, 39b, 44a, 44b of the movable plate 40 and the fixed plate 35 are shifted from each other as shown in FIG. A light transmission (light shielding) state is established. That is, the first retardation region 39a of the fixed plate 35 and the second retardation region 44b of the movable plate 40 overlap in the panel thickness direction, and the second retardation region 39b of the fixed plate 35 and the first position of the movable plate 40 are overlapped. The movable plate 40 is disposed at the light shielding position so that the phase difference region 44a overlaps in the panel thickness direction. When the movable plate 40 is set to the light shielding position in this way, light incident from one side in the panel thickness direction can be applied to one polarization layer 38, one pattern phase difference layer 39, and the other pattern phase difference layer 44 by linearly polarized light or circular light. Although the light is transmitted while being polarized, it cannot be transmitted through the other polarizing layer 43 and is in a light shielding state. That is, the other side in the panel thickness direction is in a dark state.

The width dimension of each phase difference region 39a, 39b, 44a, 44b may be an appropriate dimension so as to obtain a desired dimming state while reducing the moving distance of the movable plate 40. That is, if the width dimension of each phase difference region 39a, 39b, 44a, 44b is too large, it is necessary to move the movable plate 40 greatly. On the other hand, if the width dimension of each of the phase difference regions 39a, 39b, 44a, and 44b is made too small, the moving distance of the movable plate 40 can be reduced, but there is a tendency that misalignment between patterns tends to occur. From such a viewpoint, the width dimension of each of the phase difference regions 39a, 39b, 44a, 44b may be about 5 mm to 30 mm, and preferably about 10 mm to 20 mm.
In addition, the gap dimension along the thickness direction between the fixed plate 35 and the movable plate 40 is such that the movable plate 40 can be moved and the dimming function is not hindered, and the thickness direction can be made compact. It is good also as an appropriate dimension. For example, the gap dimension along the thickness direction between the fixed plate 35 and the movable plate 40 may be about 0.1 mm to 5.0 mm, and preferably about 0.5 mm to 2.0 mm. In addition, the gap dimension along the thickness direction between the translucent plate 34 and the movable plate 40 may be set to an appropriate size in the same manner.

2B and 3B show an example in which light is incident from the fixed plate 35 side, but light is incident from the movable plate 40 side, that is, the translucent plate 34 side. Even in this case, the transmitted light can be adjusted.
Further, the light control layers 37 and 42 in the fixed plate 35 and the movable plate 40 are not limited to the above-described examples, and various other modifications are possible. For example, the phase difference regions 39a, 39b, 44a, and 44b may be provided in a plurality of rows in the vertical direction, instead of being provided in a plurality of rows in the panel width direction. In this case, as will be described later, the moving dimension in the vertical direction of the movable plate 40 that is moved so as to draw an arc while being supported by the plurality of link arms 28, 28 may be an appropriate dimension. In addition, as the fixed plate 35 and the movable plate 40, other known light control plates can be employed. For example, it is good also as what was set as the structure which provided the light control layer in which the opaque part and the transparent part as a some area | region were formed in pattern shape.
