Abstract:
A reflection liquid crystal display including two liquid crystal layers having selected reflection wavelengths differing from each other, and two pairs of liquid crystal display panels each provided with a pair of transparent electrodes between which said respective liquid crystal layers are placed, and being obtained by stacking said two pairs of liquid crystal display panels;wherein said pairs of electrodes are electrically connected, and a voltage supply between the pair of electrodes of one liquid crystal display panel and a voltage supply between the pair of electrodes of the other liquid crystal display panel are provided by a common voltage drive circuit; a fixed or variable resistor for adjusting fluctuation characteristics of a reflection ratio with respect to drive voltages supplied between said pairs of electrodes of said two liquid crystal layers so as to be substantially identical to each other or almost the same, is provided in a voltage drive circuit of a liquid crystal layer having a smaller rise voltage in the fluctuation characteristics of said reflection ratio with respect to said liquid crystal layers.
