METHOD FOR PRODUCTION OF POLARIZING FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT |
摘要 |
<p>A method for producing a polarizing film of the present invention comprises a step (1) of preparing a lyotropic liquid crystalline solution having electric conductivity of not more than 50 µS/cm (expressed in terms of 0.05% by weight) and containing a dichroic dye and a solvent, a step (2) of preparing a base material having at least one surface subjected to a hydrophilization treatment, and a step (3) of coating the solution prepared in the step (1) on the hydrophilized surface of the base material prepared in the step (2) at a coating rate of not less than 100 mm/second, and drying the solution. The method of the present invention can easily produce a polarizing film having a high dichroic ratio.</p> |
