Abstract
An electro-optical apparatus having a color filter, and in particular, such an electro-optical apparatus having a high information content, includes a metal layer which serves as both a light shielding layer and as an electrical conductor so that the escape of light between display elements is prevented to improve contrast and also so that the wiring resistance is reduced to reduce rounding of an applied waveform to thereby prevent cross-talk, the apparatus thus being constructed to readily achieve high-image quality. A color filter is disposed on at least one of a pair of transparent substrates which hold therebetween a liquid crystal layer in cooperation with a sealing member. Transparent display electrodes are disposed above the color filter, with a smoothing layer interposed between the electrodes and the color filter. A light shielding layer formed from, e.g., a metal layer formed in a stripe-shaped patter between adjacent columns of color filter elements of the color filter, serves as an electrical conductor and is electrically connected with the transparent display-electrodes via through-holes formed in the color filter and the smoothing layer.
