The scattering property of polymer dispersed liquid crystal (PDLC) film is tested at different angles and voltages. The film is prepared via polymerition induced phase seperation method. At the 10V voltage, scattering intensity attains to the minimum when the angle is less than 26°. In contrast, the maximum appears when the angle degree exceeds 26°. In addition, the data depending on changes of applied electric field reveals a significant difference of scattering spectra in different angles. Blue light intensity increases at higher level of external voltage between 0°~5°. Ranging from 6°~25°, the intensity of scattered light increases with voltage at first and then decreases. And the magnitude of voltage in the big wave peak increases when angle degree decreases. When the scattering angle is greater than 26°, the intensity of blue light decreases with the increase of voltage. Single scattering theory is adopted to discuss and analyze the phenomenon.
