Beschreibung
Zusammenfassung:	The present invention provides an optical laminate including a polarizer in which iodine is adsorbed and oriented, and the optical laminate suppresses the rising of iodine concentration in an adhesive layer laminated thereon. The optical laminate provided by the present invention includes: a polarizing plate including a polarizer, and an optical functional layer including at least one adhesive layer, wherein the polarizing plate is a polyvinyl alcohol resin film in which iodine is adsorbed and oriented, and the adhesive layer contains a total of 1% by mass or more and 10% by mass or less of low-molecular-weight components having molecular weight of 500 or less.
