Embodiment 1

[0197]

[0198] (1) Formation of mesh metal conductive layer

[0199] Polyethylene terephthalate film (width: 600mm, length 100m) with a 100μm-thick long polyethylene terephthalate film (width: 600mm, length 100m) having an easy-adhesive layer (polyester polyurethane; thickness 20nm) on the surface is printed with dots of polyester 20% aqueous solution of vinyl alcohol. The size of one dot is a square shape with a side length of 234 μm, the interval between dots is 20 μm, and the dots are arranged in a square lattice. The printing thickness was about 5 μm after drying.

[0200] Copper with an average film thickness of 4 μm was vacuum-deposited thereon. Then immerse it in water at normal temperature, wipe it with a sponge, dissolve and remove some of the dots, then wash it with water, and form a mesh conductive layer on the entire surface of the polyethylene film after drying (refer to figure 1 (1)).

[0201] The conductive layer on the surface of the film is a square gr...

Abstract

Provided is an optical filter with a good earth electrode portion exhibiting excellent productivity, and a method for manufacturing the same. An optical filter for display comprising a transparent substrate, a metal conductive layer formed on the surface thereof, and a functional layer formed on the surface of the metal conductive layer is characterized in that a large number of insular metal conductive layers are exposed at or near the side end portion of the functional layer, and that the number of the insular metal conductive layers is 25-250 / cm2 and the area rate of the insular metal conductive layer is 2-50% in the area of an intermittent strip region defined by a strip region having a vertical width between the innermost and outermost points among the insular metal conductive layers. The optical filter for display has a conductive layer as an electrode portion.

Description

technical field [0001] The present invention relates to a field emission type display including a surface conduction electron emission type display (SED) for a plasma display panel (PDP), a cathode ray tube (CRT) display, a liquid crystal display, an organic EL (electroluminescence) display Various displays such as (FED) have an optical filter with various functions such as anti-reflection, shielding of near-infrared rays, and shielding of electromagnetic waves, its manufacturing method, and a display equipped with the optical filter, especially a PDP. Background technique [0002] It has been known for a long time that in flat panel displays such as liquid crystal displays, plasma displays (PDP), EL displays, and CRT displays, there is a problem that light from the outside is reflected on the surface and it is difficult to see internal visual information, and it has been proposed to set up a device containing Various countermeasures for optical films such as anti-reflection...
