Resin black matrix substrate and touch panel

Abstract

The purpose of the present invention is to provide a resin black matrix substrate which exhibits a low reflectivity though the resin black matrix has a small thickness and high light-shielding properties and which can thereby ensure easy color matching between the resin black matrix and a black-display area of a display. The present invention provides a resin black matrix substrate which is equipped with a transparent substrate (2), a first resin black matrix (3) formed on the transparent substrate (2), and a second resin black matrix (4) formed on the first resin black matrix (3), wherein: the first resin black matrix has a film thickness of 0.7μm or more and exhibits chromaticity coordinates of transmitted light that satisfy 0.001≤x≤0.300 and 0.001≤y≤0.250; and the two-layer black matrix composed of the first and second resin black matrixes exhibits an optical density of 3.5 or more.

Description

technical field

[0001] The invention relates to a resin black matrix substrate and a touch panel. Background technique

[0002] As a black matrix for displays, instead of metal thin films using chromium-based materials, resin black matrices that can reduce costs and environmental pollution have been developed in recent years. The resin black matrix is ​​formed by applying a photosensitive black resin composition containing a light-shielding material such as resin and carbon black on a transparent substrate such as glass and drying it to form a black film, which is finely patterned and formed by photolithography. Grid shape, thus forming a resin black matrix. Also, for example, in a recently proposed cover glass-integrated touch panel, a transparent electrode such as an ITO electrode is formed on a black matrix formed on a cover glass.

[0003] In order to see the display area of ​​the display widely, it is necessary to make the black display part of the display match the c...
