ABSTRACT:
A color liquid crystal display device includes a first substrate having thereon a layer of plural color filter segments and a layer of first transparent electrodes disposed in superposition with the layer of color filter segments, a second substrate disposed opposite to and spaced apart from the first substrate and having thereon a layer of second transparent electrodes intersecting with the first transparent electrodes, and a liquid crystal disposed between the first and second substrates so as to form plural color pixels each at a region of intersection of the first and second transparent electrodes superposed with one of the color filter segments while leaving a pixel spacing between the plural color pixels. The first substrate is provided with a first light-interrupting layer comprising a material identical to that of at least one of the plural color filter segments and disposed at a portion of the pixel spacing so as to mask the portion, and at least one of the first and second substrates is provided with a second light-interrupting layer masking a remaining portion of the pixel spacing. The first and second light-interrupting layers as a whole are effective in preventing leakage of light between color pixels, thus providing images with a high contrast and an excellent display quality.
