  • Patent number: 5307189
    Abstract: An active-matrix-addressed liquid crystal display includes an active-matrix substrate and an opposing electrode substrate on which opposing electrodes are formed. The opposing electrodes are formed into a combination of stripe electrodes each for collecting an electric field originating from the associated data line conductor, and display electrodes each corresponding to the associated pixel electrode. The stripe electrodes are connected with the associated display electrodes outside display areas. There are provided on the opposing electrode substrate a black mask formed of a photosensitive resin in which pigment of black is dispersed. The opposing electrodes may also be formed in an assembly of stripe electrodes each correspondingly to the associated pixel electrodes, no opposing electrode being disposed above the data line conductor.
