The display light of the second display 2 is arranged between the first and second displays 1 and 2 so as to face the surface, and transmits the analog light emission image to the viewer side so as to be viewed as a real image. Are reflected on the viewer side to make the virtual images V1, V2 visible. The inclination angle of the half mirror 3 with respect to the line-of-sight direction E is set to 45 degrees, for example. In this case, the second display 2 is arranged above the half mirror 3 and at a position that cannot be directly seen by the observer.

第二の表示器２は、虚像Ｖ１，Ｖ２が指針１２の回転中心領域に対応し、また、表示板１３の傾斜面１３ｅの途中に位置するよう前記表示光のハーフミラー３への投影位置を調整して配置される。これにより指針１２の回転中心部１２ｂと重なるように形成される情報表示像Ｖ１と回転中心部１２ｂの周囲を円環形状に取り巻く装飾背景像Ｖ２とは、傾斜面１３ｅの前端部である指標部１３ａよりも後方であって、傾斜面１３ｅの後端部よりも前方に位置するように視認され、傾斜面１３ｅと虚像Ｖ１，Ｖ２との距離差により奥行き感、立体感を有する表示を行うことができる。なお、第一の表示器１の非発光部は観察者からほとんど見えないか、僅かに確認される程度であるが、傾斜面１３ｅに形成される指標部１３ａの発光像が視認されることによって観察者は傾斜面１３ｅの存在を認識することができる。   The second display 2 is configured to project the display light onto the half mirror 3 so that the virtual images V1 and V2 correspond to the rotation center region of the pointer 12 and are positioned in the middle of the inclined surface 13e of the display plate 13. Adjust and arrange. Thus, the information display image V1 formed so as to overlap the rotation center portion 12b of the pointer 12 and the decorative background image V2 surrounding the rotation center portion 12b in an annular shape are an index portion which is a front end portion of the inclined surface 13e. It is visible behind 13a and ahead of the rear end of the inclined surface 13e, and a display having a sense of depth and stereoscopic effect is performed by the difference in distance between the inclined surface 13e and the virtual images V1 and V2. Can do. In addition, although the non-light-emitting part of the 1st indicator 1 is hardly visible to an observer, it is a grade which can be confirmed slightly, but when the light emission image of the indicator | index part 13a formed in the inclined surface 13e is visually recognized. The observer can recognize the presence of the inclined surface 13e.

特に、傾斜面１３ｅの後方側から前方側に向けて輝度あるいは色が変化するグラデーションを伴った装飾背景像Ｖ２を傾斜面１３ｅの途中に位置するように形成することによって、従来平面的であったグラデーション表示を立体造形部である表示板１３の傾斜面１３ｅに調和させ、実像である傾斜面１３ｅの奥行きと虚像のグラデーション表示による輝度あるいは色変化とを組み合わせた新規な立体感のある表示をなすことができ、表示装置としての商品性，デザイン性を向上させることができる。   In particular, the decorative background image V2 with gradation that changes in luminance or color from the rear side to the front side of the inclined surface 13e is formed so as to be located in the middle of the inclined surface 13e, which is conventionally flat. The gradation display is harmonized with the inclined surface 13e of the display plate 13 which is a three-dimensional modeling part, and a novel three-dimensional display is formed by combining the depth of the inclined surface 13e which is a real image and the luminance or color change by gradation display of a virtual image. Therefore, merchantability and designability as a display device can be improved.

なお、本実施形態では、立体造形部である表示板１３が、略すり鉢状の傾斜面１３ｅを有する構成について説明したが、本発明の立体造形部の形状はこれに限定されるものではなく、例えば傾斜面１３ｅを略椀形状の曲面からなる傾斜面に設定してもよい。また、第一の表示器１において、指針は表示板１３の中央に配置される必要はなく、表示板１３の外周に沿って回動するものであってもよい。   In addition, in this embodiment, although the display board 13 which is a three-dimensional model | molding part demonstrated the structure which has the substantially mortar-shaped inclined surface 13e, the shape of the three-dimensional model | molded part of this invention is not limited to this, For example, the inclined surface 13e may be set to an inclined surface made of a substantially bowl-shaped curved surface. Further, in the first display 1, the pointer does not need to be arranged at the center of the display plate 13 and may be rotated along the outer periphery of the display plate 13.
