Beschreibung
Zusammenfassung:	A method for manufacturing a pressure-sensitive adhesive layer for use on an optical film, the method includes a filtration step including filtering a pressure-sensitive adhesive coating liquid under a differential pressure of more than 0 kPa and not more than 150 kPa using a depth type filter having a filtration accuracy of 1 to 20 mum. The pressure-sensitive adhesive coating liquid contains an aqueous dispersion-type pressure-sensitive adhesive; and an application and drying step including applying the filtered pressure-sensitive adhesive coating liquid and then drying the coating liquid.
