Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an optical filter for a display device, which employs a multi-layered type electromagnetic shielding layer having the improved ability to block electromagnetic waves. SOLUTION: The optical filter for a display device includes: a transparent substrate; an electromagnetic shielding layer which is formed on the transparent substrate by layering and has a high refractive metal oxide layer and a metallic layer layered; and a grounding conductive film layer which is formed on the electromagnetic shielding layer by layering and grounds electromagnetic waves from the electromagnetic shielding layer to the outside. The optical filter can improve the ability to block electromagnetic waves. COPYRIGHT: (C)2009,JPO&INPIT
