<p>A dichroic liquid crystal display of the parallel-nematic type is caused to have a bright background, indicative of the light-transmissive state, and dark characters, in the unactivated condition, by treatment of the display electrodes to cause boundaries of the dichroic liquid crystal material to be normally homeotropic except in those areas defining a character, in which areas a pattern of silicon oxide or other parallel alignment surfactant is deposited by masking techniques.</p> |
