A color liquid crystal display depicting clear images on the screen is provided by decreasing the reflectance of external light such as solar light and room light on the black matrix. A black matrix including a laminated film is provided. The laminated film includes at least two layers each of which include at least two constituent elements. One layer is a transition layer in which the content of one of the constituent elements increases along an incident direction of external light. Also provided is a reactive sputtering apparatus suitable for preparing the laminated film for the black matrix of the present invention.
