A high quality liquid crystal display device has an alignment film with a photoconductive characteristic. Since a region having gate lines situated therebelow does not undergo irradiation of a backlight, no photoconductive effect can be obtained. A photoresist is disposed below the alignment film situated over the gate lines in order to transfer the charges in the region to an opening portion of the alignment film in an early stage. Since the photoresist has a thickness of about 1.5 μm, which is 20 times or more the 70 nm thickness of the alignment film, the resistance in the lateral direction is low in a portion where the photoresist is present. Accordingly, since the charges on the alignment film present over the gate line transfer to the opening portion of the alignment film and are eliminated in an early stage, the residual image is eliminated in the early stage.
