Abstract:
A liquid crystal display panel comprises a TFT substrate unit having a thin film transistor (TFT), a control electrode connected to the TFT, a flattening film covering the control electrode, and a pixel electrode having a cross slit and formed on the flattening film and insulated from the control electrode. An opposite substrate unit has an opposite electrode facing the pixel electrode at a predetermined position. A liquid crystal layer disposed between the TFT substrate unit and the opposite substrate includes liquid crystal molecules having negative dielectric aeolotropy. When voltage is supplied between the control electrode and the opposite electrode, an electric field is generated between them. The electric field divides the liquid crystal layer into four domains in each pixel according to the cross slit formed in the pixel electrode.
Abstract:
An electrically-floating light shielding film is formed on a glass substrate, and a signal line is formed above the light shielding film via a gate insulating film. The light shielding film is formed along the signal line, and has a width larger than that of the signal line. On an interlayer insulating film that covers the signal line, transparent electrodes of neighboring pixels are formed, and a reflective electrode extending from the transparent electrode has a frame portion disposed along the signal line. The reflective electrode is formed the interlayer insulating film. The light shielding film does not overlap the transparent electrode in a plan-view perspective and overlaps the reflective portion in a plan-view perspective. The signal line does not overlap the reflective electrode in a plan-view perspective. Hence, a semitransparent liquid crystal display device that suppresses vertical crosstalk and as well maintains a high aperture ratio is obtained.
