PROBLEM TO BE SOLVED: To allow a visual line to be guided in a desired direction by making use of saliency.SOLUTION: An outer edge of front window glass 1 for example as a visual field region is regulated by a pair of left and right front pillars 2, a roof 3 and an instrument panel 4. At a peripheral edge part of the front window glass 1 is provided a change region S11 in which saliency (visual saliency) can be partially enhanced by liquid crystals or the like for instance. For instance, during straight travelling a site HU whose saliency is enhanced can be set with respect to an upper edge part of the front window glass 1 (Figure 4), and during turning a site HR whose saliency is enhanced can be set with respect to a side edge part close to a turning direction of left and right side edge parts of the front window glass 1 (Figure 3). When a driver is looking aside, saliency can be enhanced with respect to the peripheral edge part in a direction of an object to be visually recognized which should be gazed at.SELECTED DRAWING: Figure 4 【課題】サリエンシーを利用して、所望方向に視線誘導できるようにする。【解決手段】視界領域となる例えばフロントウインドガラス１の外縁が、左右一対のフロントピラー２、ルーフ３、インストルメントパネル４によって規定されている。フロントウインドガラス１の周縁部には、例えば液晶等によって、部分的にサリエンシー（視覚的顕著性）を高くすることが可能な変更領域Ｓ１１が設定される。例えば、直進走行時にはフロントウインドガラス１の上縁部についてサリエンシーを高くした部位ＨＵを設定することができ（図４）、旋回時にはフロントウインドガラス１の左右側縁部のうち旋回方向側の側縁部についてサリエンシーを高くした部位ＨＲを設定することができる（図３）。わき見をしているときは、注視すべき視認対象物方向にある周縁部についてのサリエンシーを高くすることができる。【選択図】 図４
