POLARIZING PLATE, PRODUCTION THEREOF AND LIQUID CRYSTAL DISPLAY ELEMENT

Japanese Patent JPH03252606

A

PURPOSE:To produce a polarizing plate which includes the plural blocks varying in polarizability or polarization direction from each other within the same plane with a simplified stage by forming an org. thin film on a substrate, polymerizing a polymerizable molecule layer to a desired pattern and removing unpolymerized parts. CONSTITUTION:The org. thin film 11 oriented with the molecules in the prescribed direction within the film plane is formed on the substrate 10 and the polymerizable molecules are oriented and provided on the org. thin film 11 in correspondence to the orientation direction of the molecules of the org. thin film, by which the polymerizable molecule layer 14 is formed. The polymerizable molecule layer is polymerized to the desired pattern and the unpolymerized parts 16 of the polymerizable molecule layer 14 are removed. The polarizing plate having the plural blocks varying in the polarizability or polarization direction from each other within the same plane is obtd. The polarizing plate including the plural blocks varying in the polarizability or polarization direction from each other within the same plane is created by the simplified production process.
