。(Prior Art) In recent years, with the development of LSI technology, the spread of small electronic devices has been remarkable. These portable electronic devices, such as calculators, watches, electronic notebooks, word processors, and personal computers, often have a built-in liquid crystal display device. Additionally, in order to avoid running out of power with portable lights, some models have been manufactured that have solar cells. Examples of such things are shown in FIGS. 5(A) and 5(B). In the case of these calculators, a liquid crystal panel 1.3 and a solar cell plate 5.7 are provided side by side, and drive power is provided by private power generation.

Since they share the space, in order to keep the overall size down, it is necessary to set a certain limit on the area each of them occupies. Therefore, electronic devices with integrated solar cells currently on the market are limited to calculators with low power consumption, such as small calculators or card calculators that are equipped with extra functions to save energy.

A solar cell panel 40 is integrally stacked. The liquid crystal panel 20 includes a pair of glass substrates 21.23, display electrodes 25.27 and alignment films 29.31 formed inside each glass substrate, and a liquid crystal layer 33 sandwiched between the alignment films.
It consists of polarizing plates 35 and 37 arranged on the outside of each glass substrate, and a sealing member 39 to prevent liquid crystal from leaking. On the other hand, in the solar cell panel 40, a photoelectric conversion device 43 such as an amorphous semiconductor is provided on a glass substrate 41. Here, the polarizing plate 37 also serves as a binder for bonding the liquid crystal panel 20 and the solar cell panel 40 together.

。The liquid crystal panel 20 is driven as follows. signal line 45
An electric field is selectively applied to the liquid crystal layer for each pixel based on a control signal supplied to the display electrode via the display electrode. When an electric field is applied to a liquid crystal, its optical properties change, and when combined with a polarizing plate, it no longer transmits light. On the other hand, liquid crystals without an electric field transmit light, providing visual contrast. In this case, the important point is that light is transmitted when no electric field is applied. With this configuration,
When the liquid crystal display device is not used, the solar cell is always irradiated with light from the liquid crystal panel 20 over the entire surface.
