Abstract
Official abstract text for this publication.
There is provided an image display apparatus having high contrast and making it difficult to visually observe its conductive pattern despite including a metal nanowire or a metal mesh. An image display apparatus of the present invention includes: a circularly polarizing plate, a transparent conductive film, and a display element comprising a reflector made of a metal in the stated order from a viewer side, wherein: the transparent conductive film comprises a transparent base material and a transparent conductive layer arranged on at least one side of the transparent base material; the transparent base material has an in-plane retardation Re of from 1 nm to 100 nm; and the transparent conductive layer comprises a metal nanowire or a metal mesh.
First claim
Opening claim text (preview).
1 . An image display apparatus, comprising a circularly polarizing plate, a transparent conductive film, and a display element comprising a reflector made of a metal in the stated order from a viewer side, wherein: the transparent conductive film comprises a transparent base material and a transparent conductive layer arranged on at least one side of the transparent base material; the transparent base material has an in-plane retardation Re of from 1 nm to 100 nm; and the transparent conductive layer comprises a metal nanowire or a metal mesh. 2 . The image display apparatus according to claim 1 , wherein: the circularly polarizing plate comprises a retardation film and a polarizer; and the circularly polarizing plate is arranged so that the polarizer is on the viewer side. 3 . The image display apparatus according to claim 1 , wherein in a portion in the image display apparatus where the circularly polarizing plate and the transparent conductive film are laminated, a diffuse reflectance is reduced by 90% or more. 4 . The image display apparatus according to claim 1 , wherein the transparent conductive layer is patterned. 5 . The image display apparatus according to claim 1 , wherein the metal nanowire comprises one or more kinds of metals selected from the group consisting of gold, platinum, silver, and copper.
