ABSTRACT:
A liquid crystal display (LCD) has a plurality of pixels, each having an aperture region. A LCD display element includes a shorting metal formed outside of the pixel aperture region for converting defective pixels into black defects. The shorting metal is formed from the same material used in, and during the same manufacturing step of, forming the TFT gate electrode. Therefore, the pixel aperture ratio is not reduced and subsequent steps to form the shorting metal are unnecessary.
