ABSTRACT:
A liquid crystal display device having a matrix of pixels includes first and second light-transmissive substrates layered so as to face each other, a plurality of belt-like row electrodes spaced in parallel to each other on the first substrate, a plurality of belt-like column electrodes spaced in parallel to each other on the second substrate, a first shading layer divided into a plurality of segments partially overlying the row electrodes, a second shading layer divided into a plurality of segments partially overlying the column electrodes, and liquid crystals interposed and sealed between the first and second substrates. Each of the segments of the first shading layer are shaped and positioned so as to be opposed to each space between the column electrodes, while each of the segments of the second shading layer are shaped and positioned so as to be opposed to each space between the row electrodes.
