Liquid crystal display device
Abstract
A liquid crystal display device which comprises a pair of translucent subtrates (2,3) which are each provided on their surfaces with a plurality of parallel linear transparent electrodes (5,6), the surfaces being covered with orientation films, the pair of translucent substrates being so arranged as opposing to each other that the extending directions of the linear transparent electrodes on the two substrates intersect, a liquid crystal composition (4) being placed between the substrates, wherein each of regions between the linear transparent electrodes on at least one of the translucent substrates is shielded and cut off of light by a non-translucent low resistive conductive film (9,10) which is electrically connected with one of the adjacent linear transparent electrodes defining the regions but is disconnected from the other of the adjacent electrodes by an insulating film (7,8).
