FIG. 3 is a circuit diagram illustrating an example of a circuit configuration of a driving circuit 22a and a charging circuit 23a that form No. 3; In this example, the optical sensor 5
As the photodiode 51. The transistor Tr is used as a charge control switch, and the resistors R1 and R2 connected in series are a voltage dividing circuit for supplying a base current to the transistor Tr. Photodiode 51
Is connected between the connection point of the resistors R1 and R2 to which the base of the transistor Tr is connected and the cathode of the secondary battery 1. During the daytime, the light of the sun makes the photodiode 51 conductive, the base current does not flow through the transistor Tr, and the transistor Tr is shut off. As a result, the light emitting elements 32a... And 32b. During this period, the secondary battery 1 is charged through the resistor R3. When the photodiode 51 is cut off at night, a base current flows to the transistor Tr through the resistor R1 and the light emitting element 32a
And 32b are lit. The electric display panel of the present embodiment is
Since the thickness of the secondary battery 1 is thin and has a certain degree of flexibility, and the display portion 3 also has flexibility, the light-emitting display panel of the present embodiment can be applied to an automobile having a curved body. Can be easily installed.

You can get a board. According to the present invention, since the current collector is covered with the flexible circuit board, the flexible circuit board functions as a protective case for the current collector. In addition, since no separate protective case is provided, the overall thickness does not increase.
