Abstract

In a liquid crystal display device according to a FFS method, a line inversion drive with suppressed crosstalk due to a signal distortion is made available. Pixels A are disposed in sequence in a left to right direction in a first row, while pixels B are disposed in sequence in the left to right direction in a second row that is below the first row. In the pixel A, a pixel electrode is formed of the first layer transparent electrode and connected with a thin film transistor through a contact hole. In the pixel B, a common electrode is formed of the first layer transparent electrode and connected with a common electric potential line through a contact hole. Also in the pixel A, a common electrode having a plurality of slits is formed of the second layer transparent electrode and connected with the common electric potential line through a contact hole. In the pixel B, a pixel electrode having a plurality of slits is formed of the second layer transparent electrode and connected with a thin film transistor through a contact hole.
