ABSTRACT:
The present invention relates to a liquid crystal display device, in which a TFT array, color filters and a black matrix are provided on a single glass substrate. As a result, the second substrate of the LCD can be made thinner, thereby reducing the overall weight of the device. In addition, the LCD in accordance with the claimed invention has an improved aperture ratio. Further, less stress can be placed on the glass substrate, thereby improving yield.
