Abstract: An active matrix liquid crystal display device which has color filters disposed on a TFT (Thin-Film Transistor) substrate, and which reduces the effect of light leakage regions over data lines for an increased viewing angle. The liquid crystal display device has the data lines disposed on the TFT substrate at respective gaps between adjacent two of pixel electrodes, for supplying data signals to TFTs to drive pixel electrodes, and a black matrix disposed on the TFT substrate in association with the data lines for blocking light passing in a predetermined viewing angle range through a light leakage region created in the liquid crystal layer depending on a potential difference between adjacent two of the pixel electrodes.
