Abstract
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.
