（イ）産業上の利用分野
本発明は、液晶表示器（ＬＣＤ）やエレクトロクロミン
ク表示器（ＥＣＤ）等の受光型表示器を用いた表示装置
に関する。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a display device using a light-receiving display such as a liquid crystal display (LCD) or an electrochromic display (ECD).
（ロ）従来技術

光型であるが故に暗いところでは表示内容を読み取る事
が出来ない。(b) Prior Art Light-receiving displays, such as LCDs and ECDs, are increasingly being used in electronic calculators, wristwatches, etc. because they can be driven at low voltages and with low power consumption. However, since such a display is a light-receiving type, the display contents cannot be read in a dark place.

トラストが悪くなる、と云う新たな問題を含んでいる。In order to deal with this problem, as shown in FIG.
Alternatively, as shown in Fig. 2, a light diffusion plate (3) is provided on the back side of the display (1), and the light from the illumination lamp (4) is guided to the light diffusion plate (3) to illuminate the display (1). A configuration has been proposed in which the display is illuminated from the back side. However, with the configuration shown in Figure 1, it is difficult to uniformly illuminate the entire surface of the display (1), and with the configuration shown in Figure 2, it is difficult to uniformly illuminate the entire surface of the display (1). This includes a new problem of poor display contrast.

, ECD, and other light-receiving type display devices, which have a structure in which two transparent glass substrates are placed facing each other and the gap between them is filled with a liquid crystal substance or the like. (11) is a surface light emitter such as electroluminescence (EL) provided on the back of this display (10), and (12) is this surface light emitter (11) and the display (
10) is a transflective reflector placed between the two. The semi-transmissive reflector (12) referred to here acts as a reflector for external light and as a transparent plate for transmitted light, an example of which is shown in Figure 4. . That is, in the same figure, (20) is a transparent support plate made of polyester film or the like, one surface of which has been roughened to scatter light, and the roughened surface is coated with aluminum. A metal layer (21) with a high reflectivity such as 100% is deposited to a thickness of several 100 layers by vapor deposition or sputtering, and a surface protective film (22) made of a transparent resin is further applied to the surface of this metal layer (21). ) is provided.
斯る半透過型反射板（１２）に外光（Ａ）が照射される
と、金属層（２１〉にてその外光は反射きれ、この半透
過型反射板〈１２）は反射板として作用する事となる。When the semi-transmissive reflector (12) is irradiated with external light (A), the external light is completely reflected by the metal layer (21), and this semi-transmissive reflector (12) acts as a reflector. I will do it.

示器（１０〉を透過型の表示器として作用させる。Therefore, as shown in Fig. 3, such a transflective reflector (12)
is placed between the display device (10) and the surface light emitter (11), so that when the surroundings are bright and external light arrives, the external light is transferred to the semi-transmissive reflector (12). The display (10>) acts as a reflective display, and when the surroundings become dark and the surface light emitter <11) is allowed to emit light, the illumination light from the surface light emitter (11) becomes semi-transparent. The display device (10) is illuminated from the back side through the reflective plate (12), causing the display device (10> to function as a transmission type display device).
