| description | A polarizable compact is provided with high productivity, which makes a polarizing sheet resistant to the occurrence of color unevenness and voids and also resistant to the occurrence of variations in polarization degree accompanying thermal shrinkage and the like of a protective layer (protective film). A polarizable compact is used for glasses. An injection-molded portion made of a transparent plastic material is thermally bonded to the concave surface side of a polarizing sheet having a predetermined curvature radius. The polarizing sheet has a polarizer layer held between first and second protective layers respectively serving as a convex surface side and a concave surface side. Both the first and second protective layers are formed from transparent films by a casting method with retardation (Re)≤50 nm. The transparent films for the first and second protective layers are respectively formed from an acylcellulose-based film and a polyamide-based film. |
