HIGH APERTURE RATIO TRANSFLECTIVE LIQUID CRYSTAL DISPLAY WITH PVA MODE

摘要

PURPOSE: A PVA(Patterned Vertical Alignment) mode semitransparent LCD device in which an aperture ratio is improved is provided to improve the optical efficiency by arranging a data line within a unit pixel at the center of a pixel and setting up a reflective region on the data line. CONSTITUTION: A common electrode and a pixel electrode(410) within the unit pixel of a PVA mode semitransparent LCD device are rotated at 90 degrees and arranged. A data line is moved to the center within the unit pixel. The common electrode and pixel electrode have a slit shape. A reflective plate(440) is formed on the data line in order to form a reflective region. A broadband half-wavelength plate is formed in a polarizing plate of the PVA mode semitransparent LCD device by using a quarter wavelength plate and a half-wavelength plate. The ON/OFF states of a transmission region and the reflective region coincide with each other.
