いる。(Prior art) As a display device of this type, for example, one in which the display surface of a liquid crystal cell serving as the display device is reflected by a reflector plate, and the display form is read by the reflected display virtual image projected on the reflector plate is actually used. It is known from Publication No. 56-53369. As shown in Figure 5, a planar reflection plate 2, which is approximately the same size as the display surface, is installed below the liquid crystal cell 1 at an angle of approximately 45 degrees, thereby reading the reflected display virtual image at a ratio of 1:1. It is formed like this.

In general, since the reflector 2 is provided at an angle of approximately 45 degrees, it is necessary to provide a large storage space for the reflector, that is, a large depth dimension.For example, in the case of an automobile display device, the instrument housing 4 tends to be large, as shown in Fig. 5. My face was warm.

面に近い方が好ましい。(Embodiment) FIGS. 1 to 3 show a first embodiment of the present invention, which is a display device for an automobile. Reference numeral 11 designates a meter hood having a display window 12. The display device 13 is housed with its display section 14 facing downward, and a reflecting mirror 15 is arranged at an angle at a position corresponding to the display window 12 below. In that case, in this embodiment, the reflecting mirror 15
are placed at an angle of approximately 20 degrees. The size of the display unit 14 of the display unit 13 is the same as that of the reflector 15.
Compared to the size of the virtual image portion 16 reflected and displayed, the width dimension is 1:1 and the vertical width dimension is 1:2.5. Further, on the mirror surface of the reflecting mirror 15, convex portions 17 having a serrated cross-section are formed in the form of fine parallel lines in the horizontal direction, and the convex portions 17 are vertically parallel to the viewing direction as shown in FIG. The surface 18 is formed with an inclined surface 19 such that an incident light beam from the viewing direction is reflected toward the display section 14 of the display device 13. Therefore, as shown in Figure 3, the aspect ratio is 1/
The display section 14 of the 4:1 display 13 is enlarged and displayed on the reflecting mirror 15, and a virtual image with a size ratio of 1:1 both vertically and horizontally is obtained. Note that the magnification display rate of the vertical width of the reflecting mirror 15 depends on the inclination angle of the arrangement of the reflecting mirror 15 and the convex portion 1.
7 by freely selecting the inclination angle of the inclined surface 19. Further, in FIG. 4, the display 13 is housed in the meter hood 11 below the display window 12 so that the display is reflected on the reflector 15.
Further, it is preferable that the vertical surface 18 of the convex portion 17 be close to a surface parallel to the viewing direction.
上記のように反射鏡１５による拡大表示作用に
よつて表示器１３の大きさは例えば従来に比して
その奥行き寸法が小さくてすみ、これによつて小
形になり表示器１３を収納するメータフード１１
もそれだけ小さいものになる。 As described above, due to the magnifying display effect of the reflector 15, the size of the display 13 can be reduced, for example, in the depth dimension compared to the conventional one, and thereby the meter hood that houses the display 13 is made smaller. 11
becomes that much smaller.
さらに、反射鏡１５の傾斜角が急なため奥行き
が小となり全体の計器ハウジングの奥行き寸法を
小さくすることが可能となる。なお、昼間は外光
を取り入れ、夜間は内部光によつて表示器を照明
するタイプ、あるいは常時内部光によつて照明表
示するタイプ、あるいは夜間においてスイツチの
作動によつてのみ内部照明灯を点灯させて照明表
示するなどこの種の反射型の表示装置であればす
べて適用することが可能である。 Furthermore, since the angle of inclination of the reflecting mirror 15 is steep, the depth is small, making it possible to reduce the depth dimension of the entire instrument housing. In addition, there are types that take in outside light during the day and illuminate the display with internal light at night, types that constantly use internal light to illuminate the display, or types that only turn on the internal lighting at night when a switch is activated. It is possible to apply this type of reflective display device to any type of reflective display device, such as one that performs illumination display.
