Abstract
With a liquid crystal device of a type wherein light-shielding films are provided below TFTs, in order to enable high-quality image display with a relatively simple configuration using the light-shielding film and capacitance lines, the liquid crystal device may consist of a liquid crystal layer held between a pair of substrates, and pixel electrodes provided in a matrix on a TFT array substrate. A plurality of light-shielding films formed of metal with a high melting point and divided into strips are formed below the pixel TFTs, scanning lines, capacitance lines, and so forth, and the capacitance lines and light-shielding films are electrically connected via contact holes. The resistance of the capacitance lines is lowered by the light-shielding films.
