The present invention is to provide a digital radio receiver using a carrier offset compensating circuit capable of compensating for carrier offsets even in a TDD communication system, and extending the range that can cope with offset frequencies to secure stable operation. The method includes applying a solution comprising an organosilane quaternary compound to the surface such that the surface is wet. The light guide plate is disposed on a side of the second substrate that is not in contact with the liquid crystal layer, and includes a light incident surface.
