Abstract:
1. A liquid crystal display device capable of displaying an image, comprising: a liquid crystal panel; an irradiation section for irradiating the liquid crystal panel with light; a control device for controlling driving of the liquid crystal panel; and a plate-like member attached to a part of the liquid crystal panel; wherein: a light guiding section for collecting natural light and propagating the light is located on a first surface of the plate-like member; the light guiding section is connected to the irradiation section; a plurality of optical sensors each for detecting an amount of light are provided on the first surface of the plate-like member; the irradiation section includes a plurality of LED elements; the control device is connected to an LED driving section for controlling an amount of light to be emitted from each of the plurality of LED elements; the control device is connected to the optical sensors; the control device is structured to control an amount of light to be emitted from each of the plurality of LED elements by use of the LED driving section based on the amounts of light detected by the optical sensors; the plate-like member is pivotable about a rotation shaft located in the vicinity of a top end of the liquid crystal panel; and a solar panel is located on a second surface of the plate-like member which is opposite to the first surface.
