The distortion of electric field and abnormal light transmission characteristics due to foreign particles were studied in IPS and TN mode TFT LCD. The dielectric and ionic particles with varying sizes were considered for the simulation according to their electric characteristics. The simulation shows that the foreign particle introduced into a pixel changes the electric fields within a pixel and affects the light transmission characteristics of the pixel. In both TN and IPS mode TFT LCD, the presence of the ionic particle affects the light transmittance a great deal.
