PROBLEM TO BE SOLVED: To make a display usable for a long time using the internal power source by providing a photoelectric converter that converts surrounding light to electric energy. SOLUTION: An oppositely facing substrate 2 is constituted of a glass substrate 14, a solar cell 10 provided on this glass substrate 14, a plastic-made antireflection film 15 installed on this solar cell 10 for the purpose of preventing the reflection of visible radiation, a reflected light absorbing film 16 that is provided on the antireflection film 15 and that is composed of a color filter for absorbing the visible radiation unpreventable by the antireflection film 15 and unabsorbable by the solar cell 10, and a counter electrode 17 consisting of ITO and transparent against the visible light. At the time of a display state with a high light transmittance of a liquid crystal layer 3, the layer 3 transmits light, which impinges on the solar cell 10, generating an electro motive force. Consequently, by utilizing it as a power source, the reduction of electro motive force of the internal cell can be supplemented, enabling the device to be used for a long time. |
