    摘要： One picture element is divided into first and second sub-picture element regions. A sub-picture element electrode connected directly (not via capacitive coupling) to a source electrode of a TFT is placed in the first sub-picture element region and a sub-picture element electrode capacitively coupled to a control electrode connected to a source electrode is placed in the second sub-picture element region. A transparent resin film is formed in the first sub-picture element region and this makes a liquid crystal layer thickness in the second sub-picture element region thicker than that of the first sub-picture element region.
