<P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device attaining power saving, and to provide an illumination device unit and a solar cell which are used in the liquid crystal display device. <P>SOLUTION: A liquid crystal display device 10 includes: a liquid crystal panel 21 having a display surface 22; a backlight 61 that is arranged in an opposite side to a side in which the display surface 22 is formed with respect to the liquid crystal panel 21 and irradiates the liquid crystal panel 21 with illumination light; and a light-transmitting solar cell 31 which is arranged between the liquid crystal panel 21 and the backlight 61 and can transmit the illumination light that has been emitted from the backlight 61 toward the liquid crystal panel 21. The solar cell 31 has a photoelectric conversion layer 32 for performing photoelectric conversion using external light having transmitted through the liquid crystal panel 21, and a photoelectric conversion layer 42 for performing photoelectric conversion using the illumination light having been emitted from the backlight 61. <P>COPYRIGHT: (C)2013,JPO&INPIT |
