Transparent laminate

Abstract

A transparent laminate useful as an optical filter having an excellent anti-reflection property, a near-infrared ray absorption property, an electromagnetic wave-shielding property, durability, visibility and reduced weight. The transparent laminate comprises a first laminate portion including a first transparent substrate, an anti-reflection layer and a near infrared ray-absorption layer respectively formed on the front and back surfaces thereof; and a second laminate portion including a second transparent substrate and an electromagnetic wave-shielding layer formed on one surface thereof. The first transparent substrate and the second transparent substrate are integrally jointed together; i.e., the near infrared ray-absorption layer and the electromagnetic wave-shielding layer or a metal mesh layer are integrally joined together via an adhesive layer.

Description

technical field [0001] The present invention relates to a transparent laminate, and more specifically, to a transparent laminate suitable for use as an optical filter on a display surface of a display device such as a plasma display. Background technique [0002] A plasma display device (hereinafter sometimes referred to as PDP) has the following composition: a front glass substrate with a display electrode, a bus electrode, a dielectric layer and a protective layer, and a front glass substrate with a data electrode, a dielectric layer and a stripe barrier A rear glass substrate having a phosphor layer on a barrier rib is bonded so that the electrodes are perpendicular to each other to form a cell, and a discharge gas such as xenon is sealed in the cell. Plasma display devices emit light by applying a voltage between the data electrode and the display electrode to generate xenon discharge, and the xenon ions in the plasma state generate ultraviolet rays when they return to t...

Problems solved by technology

However, for the above-mentioned plasma display device, for example, as described in JP-A-10-319859 (Patent Document 1), a PDP device including a light-emitting mechanism is separated from it by a certain space and installed through a glass panel. The optical filter mechanism is composed of a film laminate formed by laminating several layers of films, so it cannot be said that it has achieved sufficient weight reduction. In fact, if you want to hang it on the wall of a general household house In general, the wall needs to be very strong, and sometimes the wall itself needs to be reinforced in advance

In addition, due to the reflection of the front glass part of the PDP, the surface and the back of the optical filter, there are disadvantages such as double reflection of external light on the display surface.
