Abstract
A liquid crystal display (LCD) whose red, green and blue filters are formed on different substrates is disclosed. The LCD thus controls the width of the black matrix, enlarges the width of the filters and easily forms a color filter, having lower colorimetric purity and transmissivity than the other color filters. In an embodiment, both the blue filter and the black matrix are formed on the top glass substrate, while the red and green filters are formed on the bottom glass substrate opposite from the top substrate such that the red and green filters of the bottom substrate are aligned with the blue filter of the top substrate.
