COLOR FILTER SUBSTRATE, LIQUID CRYSTAL DISPLAY DEVICE, LAMINATE AND METHOD FOR MANUFACTURING COLOR FILTER SUBSTRATE

To provide a color filter substrate capable of suppressing decrease in the contrast of a liquid crystal display device, a liquid crystal display device using the color filter substrate, a laminate to be used for a liquid crystal display device, and a method for manufacturing a color filter substrate.SOLUTION: A color filter substrate 10 includes: a color filter member 2 having a color layer of a plurality of colors on one surface of a transparent substrate layer 21; a first optical functional member 1A disposed on the color layer side of the color filter member and having a first retardation layer containing a liquid crystal material; and a second optical functional member 1B disposed on the transparent substrate layer side of the color filter member and having a second retardation layer containing a liquid crystal material. Among regions of a first retardation layer 11A located on the color layer of the plurality of colors, a region where the difference between the maximum film thickness and the minimum film thickness of the first retardation layer in a pixel is smallest is located on the color layer of a color having highest brightness in the color layer of the plurality of colors.SELECTED DRAWING: Figure 1 【課題】液晶表示装置のコントラストの低下を抑制することができるカラーフィルタ基板、これを用いた液晶表示装置、液晶表示装置に用いられる積層体、およびカラーフィルタ基板の製造方法を提供する。【解決手段】透明基材層２１の一方の面に複数色の着色層を有するカラーフィルタ部材２と、カラーフィルタ部材の着色層側の面に配置され、液晶材料を含有する第１の位相差層を有する第１の光学機能部材１Ａと、カラーフィルタ部材の透明基材層側の面に配置され、液晶材料を含有する第２の位相差層を有する第２の光学機能部材１Ｂと、を備えるカラーフィルタ基板１０であって、各色の着色層上に位置する第１の位相差層１１Ａの各領域のうち、画素内の第１の位相差層の最大膜厚と最小膜厚との差が最も小さい領域が、複数色の着色層のうち、輝度が最も高い色の上記着色層上に位置している。【選択図】図１
