Keywords:Pixel per Inch, Pixel Boundary, LC Efficiency, Voltage-Transmittance Curve

Impacts of pixel size on liquid crystal efficiency and voltage-transmittance curve at pixel boundary area are fully investigated by 3D simulation and observation. It is found that smaller pixel or domain size will suffer from efficiency or Tr% loss slightly (e.g. about 7% from 75UD to 55UD).
