Abstract
The invention provides a liquid crystal display device having a structure in which light reflection on lines can be suppressed and reduction in contrast of the liquid crystal display device can be prevented without providing a shielding film on a color filter of an opposite substrate portion. In the liquid crystal display device according to the invention, a shielding film is not provided in a color filter provided on a substrate on the opposite substrate portion side. A signal line is formed of a transparent conductive material such as ITO, amorphous ITO or the like. Consequently, light incident from the surface of the liquid crystal display device passes through the back face of the liquid crystal display device without causing surface reflection even if the light hits upon the signal line in an interval between pixel electrodes. Consequently, it is possible to prevent reduction in contrast caused by the light reflected on the signal line.
