Abstract:
There are provided a substrate which has solved an unsatisfactory adhesion problem of a seal part in a liquid crystal cell comprising a retardation layer provided on the inner side of the cell, and a liquid crystal cell using the substrate. A color filter substrate includes a substrate 11, and at least a black matrix layer 12, a color filter layer 13, and a retardation layer 14 stacked on the substrate 11. The black matrix layer 12 and the color filter layer 13 are stacked on the substrate it while providing a margin around the periphery of the substrate 11. The retardation layer 14 is stacked on the black matrix layer 12 and the color filter layer 13 in a larger area than the area where the black matrix layer 12 and the color filter layer 13 are stacked. The substrate 11 in its margin, where neither the black matrix layer 12 nor the color filter layer 13 is stacked, is a predetermined seal area.
