Abstract
PURPOSE: To provide a display device, which is easy in assembly, by forming a tooth-shaped transparent electrode in one of substrates, which are subjected to directing treatment, and by arranging a reflecting plate to drive a preset liquid crystal.
CONSTITUTION: There is interposed between tow transparent substrates 1 and 4, which are subjected to directing treatment, a liquid crystal, in which n-type dichroic nematic liquid crystal molecules 10 and n-type nematic liquid crystal molecules 9 are arranged vertically. A reflecting plate 14 is arranged to face the substrate 4. If a voltage is impressed upon the tooth-shaped transparent electrodes 5 of the substrate 4, the molecules 9 and 10 are directed horizontally by the electric field, which is generated between the electrodes 5, to accomplish the dichroic display with the light of the incidence, which is reflected by the reflecting plate 14. As compared to the case, in which opposed electrodes are arranged on the substrates 1 and 4, the liquid crystal display device according to the construction requires no positioning of the electrodes so that it can be assembled with ease. Incidentally, if a polarizing plate is interposed between the substrate and the reflecting plate, the display brightness can be controlled.
