Yes. Therefore, the pointer 3040 is easily visually recognized through the transparent pixel region.
- an object (diffusion plate 3033) existing on the back side of the liquid crystal panel 3020 is hardly visible. Therefore, the pointer 3040 visually recognized through the light-transmitting pixel region becomes conspicuous, and it is promoted that a line of sight is attracted to the pointer 3040. That is, the attractiveness to the pointer 3040 can be improved.
- the transmittance of the translucent pixel region is increased to such an extent that the entity (pointer 3040) is visible, and the entity display mode (see FIG. 43) is not visible.

Therefore, when the viewer looks at the object in focus, the virtual image V displayed superimposed on the object is also clearly visible. Therefore, it is possible to promote the illusion that the color or pattern of the virtual image V superimposed on the entity is the color or pattern of the entity itself.
- the distance L1 from the virtual image liquid crystal panel 3074 to the reflecting surface 3020a and the distance L2 from the reflecting surface 3020a to the virtual image V coincide with each other.

(第2実施形態)
本実施形態では、図8および図9に示すように、実体物には、表示面1020aの視認可能領域の外縁に沿って延びる壁部材1400、および指針1040が含まれている。視認可能領域の外縁は、見返し板1011の開口部1011aの壁面により特定される。壁部材1400は、上記外縁に沿って環状に延びる筒形状であり、液晶パネル1020に近づくほど開口面積が拡大する形状である。壁部材1400の筒形状内部に指針1040は位置する。壁部材1400は透光性を有する樹脂製である。
(第3実施形態)
図10に示すように、本実施形態では、バックライト1030(第1バックライト)と液晶パネル1020との間に加飾板1440が配置されている。加飾板1440は透光性を有する樹脂製の板であり、加飾板1440の所定領域には、光の透過を遮断する遮光領域P1050が設けられている。図中の網点は遮光領域P1050を示す。例えば、加飾板1440のうち、黒色等の不透光性を有する塗料を所定領域に塗布することで遮光領域P1050が形成され、塗布されていない部分が透光領域P1050a、P1050b、P1051、P1052に相当する。
(第4実施形態)
上記第3実施形態では、第2バックライト1300の点灯時には、バックライト1030を消灯させている。これに対し本実施形態では、第2バックライト1300の点灯時にも、バックライト1030を点灯させている。但し、バックライト1030の色を第2バックライト1300とは異ならせている。
(第5実施形態)
図17に示す表示装置Dは、車両のインストルメントパネルに組み付けられた車両用の表示装置である。表示装置Dは、車両の走行速度や車載バッテリの電力残量等、車両の状態を表した各種物理量の変化を表示したり、各種の異常が生じた場合にその旨を表示したり、演出画像を表示したりする。
(第6実施形態)
本実施形態では、図23に示すように、特定画素領域G2010に数字画像G2013が表示されている。数字画像G2013は、目盛り画像G2011に対応する数値を表した画像である。そして、数字画像G2013が部分的に指針部2041と重なっている時、数字画像G2013のうち指針部2041と重なっている部分を表示させないようにしている。例えば、図23に示されている複数の数字画像G2013のうち、「0」「40」「60」「80」「100」「120」「140」を示す数字画像は指針部2041と重なっていないため、数字の全体が数字画像として表示されている。これに対し「20」を示す数字画像は、部分的に指針部2041と重なっており、その重なった部分は数字画像を表示させていない。
(第7実施形態)
本実施形態では、図24および図25に示すように、実体物には、表示面2020aの視認可能領域の外縁に沿って延びる壁部材2400が含まれている。視認可能領域の外縁は、見返し板2011の開口部2011aの壁面により特定される。壁部材2400は、上記外縁に沿って環状に延びる筒形状であり、液晶パネル2020に近づくほど開口面積が拡大する形状である。壁部材2400の筒形状内部に指針部2041は位置する。壁部材2400は透光性を有する樹脂製である。

(第15実施形態)
上記第14実施形態では、図44に示すように、実体物と液晶パネル3020の間の位置に虚像Vの焦点距離が設定されている。そのため、視認者が実体物に焦点を合わせて見た場合に、実体物と重ねて表示されている虚像Vがぼやけて見えることとなり、ぼんやりとした浮遊感のある見栄えにすることができる。これに対し第15実施形態では、図51に示すように、虚像Vの焦点距離を、実体物である指針3040および表示物3050の焦点距離と一致させている。そのため、視認者が実体物に焦点を合わせて見た場合に、実体物と重ねて表示されている虚像Vも鮮明に見えることとなる。そのため、実体物に重ねる虚像Vの色や模様が、実体物そのものの色や模様であるかのように錯視されることを促進できる。
(第16実施形態)
図52に示す表示装置Dは、車両のインストルメントパネルに組み付けられた車両用の表示装置である。表示装置Dは、車両の走行速度や車載バッテリの電力残量等、車両の状態を表した各種物理量の変化を表示したり、各種の異常が生じた場合にその旨を表示したり、演出画像を表示したりする。
