Abstract
A liquid crystal display device including a first substrate and a second substrate having a liquid crystal composition layer disposed therebetween, a black matrix formed on at least one of the first substrate and the second substrate, and a video signal line formed between a face of the first substrate and a face of the liquid crystal composition layer. At least one pixel electrode is formed at each of pixels adjoining each other through the video signal line and fed with a selected video signal through the video signal line, and at least one counter electrode is fed with a counter voltage. An optical transmissivity of the liquid crystal composition layer is controlled by an electric field component which is generated between the pixel electrode and the counter electrode. One of the counter electrodes of the individual pixels is positioned at opposite sides of the video signal line, and the black matrix is formed over the video signal line. The black matrix has a widthwise contour which extends at least as far as the counter electrodes positioned adjacent to the opposite sides of the video signal line.
