Power generating liquid crystal displays using a reflective polariser and a solar cell

摘要

An object of the present invention is to integrate a solar cell into a liquid crystal display device so as to integrate the same, but not to lower the image quality such as the contrast ratio without reducing the size of the screen. Accordingly, the present invention provides a liquid crystal display device in which a reflective polarizer is disposed between a liquid crystal cell and a solar cell, and the incident light is reflected or transmitted by the reflective polarizer and functions as a liquid crystal display device in which the liquid crystal cell controls the polarization state of light , And some light is absorbed by the solar cell to produce electric power.
