Beschreibung
Zusammenfassung:	PURPOSE: A fabrication method of an optical lamination, an oval polarizer consisting of the optical lamination, a circular polarizer, and an LCD device are provided and to laminate an optical element consisting of a liquid crystal material layer which does not have a supportive substrate film. CONSTITUTION: A liquid crystal material layer where a liquid orientation is fixed is adhered to a re-exfoliative substrate via an adhesive layer, and an orientation substrate is exfoliated to transfer the liquid crystal material layer to the re-exfoliative substrate. A lamination(A) consisting of the re-exfoliative substrate, the adhesive layer, and the liquid crystal material layer is obtained through the first process. A liquid crystal material layer is unified with the liquid crystal material layer via an adhesive and an adhesive layer, and a lamination consisting of the re-exfoliative substrate, the adhesive layer, the liquid crystal material layer, the adhesive layer(adhesive), the liquid crystal material layer, and an orientation substrate is obtained through the second process. The re-exfoliative substrate and the orientation substrate are exfoliated, and a polarizer is unified with the adhesive layer or the liquid crystal material layer through the third process.
