この発明は太陽電池付きカラー表示素子に関す

た。 Conventionally, solar cells have been put into practical use by being incorporated into watches and calculators. However, since the black or similar color of the solar cells was visible as is, it was not aesthetically pleasing and was not desirable in terms of design.
この発明は、太陽電池の前面をカラー表示に使
うようにすることによつて上記従来の欠点を解決
するものである。 The present invention solves the above-mentioned conventional drawbacks by using the front side of the solar cell for color display.
つぎにこの発明の実施例について説明する。 Next, embodiments of the invention will be described.

る。 In FIG. 1, a selective scattering layer 2 is provided in front of a solar cell 1, and a transmission type display element 3 is further provided in front of the selective scattering layer 2.
will be provided. The solar cells 1 currently in practical use include amorphous silicon and single crystal silicon, and when these are used, the wavelengths that contribute to the power generation of the solar cell are as shown in the second diagram. As the selective scattering layer 2, a layer in which microencapsulated cholesteric liquid crystal is dispersed in a binder and coated, a cholesteric polymer sheet, or the like is used. This selective scattering layer 2
scatters light of a specific wavelength in the visible range and transmits residual light. Therefore, it is better to shift the scattered light from the wavelength that contributes to power generation by the solar cell 1.
The light of the wavelength selectively scattered by the selective scattering layer 2 is not completely blocked by the cholesteric liquid crystal, and nearly half of it is transmitted, so power can be generated even if the selective scattering layer of any color in the visible range is used. It will never go away. However, it is better to shift it to improve power generation efficiency. For example, when a blue selective scattering layer 2 is used, its light transmittance is shown by curve A in FIG.

字等が表示されることになる。 Therefore, in this case, whether amorphous silicon or single-crystal silicon is used as the solar cell 1, there is almost no drop in power generation efficiency. As the transmission type display element 3, a twisted nematic type liquid crystal display element, a guest-host type liquid crystal display element, a transmission type electrochromic display element, etc. can be used. This transmissive display element 3 has display segment patterns such as characters and figures formed thereon. Now, as the transmissive display element 3, a positive display type guest screen containing black dichroic dye is used.
When a host-type liquid crystal display element is used and a blue cholesteric polymer sheet is used as the selective scattering layer 2, when a display effect is performed, the incident light is transmitted through the part of the liquid crystal display element to which no driving voltage is applied. The blue light is scattered and reflected by the selective scattering layer 2 and comes out through the liquid crystal again. Therefore, that part appears blue. The remaining light that passes through the selective scattering layer 2 contributes to power generation by the solar cell 1. On the other hand, the portion of the display segment to which the driving voltage of the liquid crystal display element is applied is blocked from light and appears black. As a whole, characters, etc. will be displayed in black on a blue background.

散乱層2の作用は上述の実施例と同様である。 In the above-mentioned embodiment, a cholesteric liquid crystal is used as the selective scattering layer 2, but the selective scattering layer 2 is not limited to this, and may be any layer as long as it has transmission and color scattering functions that enable power generation by a solar cell. As shown in the figure, the selective scattering layer 2 may be formed by stacking a dichroic mirror 4 and a diffuse transmission layer 5. The dichroic mirror 4 reflects light of a specific wavelength in the visible range and transmits the remaining light. The diffuse transmission layer 5 may be made of glass or plastic whose surface has been subjected to a blast treatment, or may be made of a transparent plate sprayed with a matte lacquer. The action of the selective scattering layer 2 in this case is the same as in the above embodiment.

つてもよい。 The above example describes a case where one transparent display element 3 is provided corresponding to one solar cell 1, but in addition, a plurality of solar cells 1 may be connected and the gaps are painted in the same color as the solar cells. The selective scattering layer 2 and the transmission type display element 3 may be provided thereon.

い。 According to the color display element with a solar cell according to the present invention having the above-described configuration, the solar cell is hidden behind the display element, so the aesthetic appearance is maintained and there is a large degree of freedom in design when used in various display devices. .
