摘要:
A metal-clad laminate according to the invention is provided with an insulating layer and a metal layer present on at least one surface side of the insulating layer. The insulating layer is formed by laminating at least two layers, which are a first resin layer and a second resin layer disposed between the first resin layer and the metal layer. The first resin layer and the second resin layer each include a cured product of a resin composition. The resin composition in the first resin layer is different from the resin composition in the second resin layer. A relative permittivity of the cured product of the resin composition included in the second resin layer is lower than a relative permittivity of the cured product of the resin composition included in the first resin layer.

A metal-clad laminate of the present invention comprises an insulating layer, and a metal layer that is present at least on one surface side of the insulating layer. The insulating layer is a laminate of at least three layers: a center layer, a first resin layer that is present on one surface side of the center layer, and a second resin layer that is present on the other surface side of the center layer. The center layer, the first resin layer and the second resin layer each contain a cured product of a respective resin composition. The elastic modulus of the cured product of the resin composition contained in the center layer is lower than the elastic moduli of both the cured product of the resin composition contained in the first resin layer and the cured product of the resin composition contained in the second resin layer.

Provided is a liquid crystal display device that makes it possible to prevent coating unevenness of a colored layer from occurring. The liquid crystal display device includes a first colored layer, a second colored layer and a third colored layer, which layers are formed in a display area. In the liquid crystal display device, the first colored layer is arranged in a grid pattern in a manner of surrounding the second colored layer and the third colored layer. In addition, when (n, m) denotes the coordinates of a pixel having a grid square formed therein in the display area, grid squares are omitted in at least pixels of (n−1, m−1), (n−1, m+1), (n+1, m−1) and (n+1, m+1).
