LIQUID CRYSTAL DISPLAY DEVICE AND LIQUID CRYSTAL DISPLAY PANEL THEREOF

摘要

The present invention provides a liquid crystal display device and a liquid crystal display panel thereof. Each pixel unit comprises staggered reflecting regions and transmitting regions. The reflecting region is corresponded with a reflective layer and a common electrode. The transmitting region is corresponded with a pixel electrode and a common electrode. By applying voltages to the pixel electrode and the common electrode, the transflective display of the liquid crystal display panel can be achieved. With the aforesaid arrangement, the electrode structure employed by the present invention is capable of reducing the drive voltage, raising the luminous transmittance and enlarging the view angle. With the vertical orientation, the dark-state light leakage can be diminished to promote the display contrast. The difficulty of the manufacture process can be reduced with the single cell thickness structure.
