Aluminum alloy foil that, when used for battery packaging material, unlikely to develop pinholes or cracks even during molding of battery packaging material, and can exhibit excellent moldability. Aluminum alloy foil, which is for use in battery packaging material, wherein, with respect to cross section obtained by cutting aluminum alloy foil in vertical direction to rolling direction of aluminum alloy foil, which is a vertical direction to surface of aluminum alloy foil, proportion of total area of a {111} plane in total area of crystal planes of face-centered cubic structure, obtained by performing crystal analysis using EBSD method, is 10% or more; and with respect to cross section, a number average grain diameter R (&#x3bc;m) of crystals in face-centered cubic structure, obtained by performing crystal analysis using EBSD method, satisfies following equation: number average grain diameter R&#x2264;0.056X+2.0, where X=thickness (&#x3bc;m) of aluminum alloy foil.

There is provided a color filter which can be manufactured by a simplified process and which will not short-circuit an electrode of a TFT substrate. The color filter includes a substrate, and a red layer, a green layer and a blue layer, formed on the substrate. When forming the green layer and the blue layer, these layers are not only formed on the substrate, but also laminated on the red layer to form a spacer comprised of the green layer and the blue layer, laminated on the red layer. The color filter further includes a transparent electrode layer which covers the substrate, the red layer, the green layer, the blue layer and the spacer, and an insulating black matrix layer formed on predetermined areas of the transparent electrode layer.
