OPTICAL FILTER

摘要

PROBLEM TO BE SOLVED: To provide an optical filter for improving contrast of images by reducing reflection caused by external light on a display face such as a PDP and preventing the images from blurring even when exposed to external light.

SOLUTION: The film-like optical filter 11 includes: an electromagnetic wave shielding laminate layer 12 having an electromagnetic wave shielding layer 22 comprising metal meshes formed on the surface of a transparent base material 21 having flexibility, and a transparent adhesion layer 23 to be bonded on a display face 17a of a PDP module 17 on a rear face; an external light shielding layer 13 integrated through a transparent adhesion layer 33 with the electromagnetic wave shielding laminate layer 12; and a release film 16 bonded on the transparent adhesion layer 23 of the electromagnetic wave shielding laminate layer 12. The optical filter is directly bonded on the display face 17a of the PDP module 17 by peeling the release film 16.
