We develop a new characterization technique for rubbed polymide film for liquid crystal display. This technique enables to observe the optical anisotropy of the rubbed polymide film on one pixel with a high numerical aperture microscope objective, optical polarized devces, and an area CCD camera. We selected the circular polarization as the polarization of the incident light beam to the microscope objective. In the case of the circular polarizedlight beam, the polarization of the incident light to the sample is all incident orientation to the sample. Then the circular polarized incident light beam to the microscope objective enables to measure on one time from all incident orientation without the rotation of TFT panel. This brings a short time of the measurement and an accuracy of the measurement point. We demonstrated a performance of our new technique with a dismantled TFT panel.
