PRODUCTION OF OPTICAL ELEMENT AND MICROREGION OF LIQUID CRYSTAL POLYMER LAYER USED THEREFOR

摘要

PURPOSE: To provide an optical element which producing method capable of making a liquid crystal high contrast and colored, and improving transmittance and visual angle. CONSTITUTION: A liquid crystal polymer layer formed on an oriented substrate has microregions of liquid crystal polymers formed in such a manner that the min. distance (Lmin ) is controlled to <=10mm and Lmin /d (wherein, d is the thickness of the liquid crystal polymer layer) is controlled to >=10. These microregions are adhered with an adhesive to another substrate. Then the oriented substrate is peeled from the other substrate so as to transfer the microregions of liquid crystal polymer layers to the other substrate.
