Abstract
The present invention provides an inexpensive stacked type reflection liquid crystal display, which can be obtained by stacking two liquid crystal display panels, and a method for producing the same, wherein a two-layered type reflection liquid crystal display is produced, having a blue display panel and a yellow display panel stacked therein, which is provided with segment electrodes and ′, common electrodes and ′, and glass substrates ′ and ′ in a state where two liquid crystal layers and ′, the selected and reflection wavelengths of which are mutually different from each other, are placed therebetween. The fluctuation characteristics of the reflectivity with respect to drive voltages of two liquid crystal layers and ′ are adjusted so that these characteristics are made coincident with each other. Segment electrodes and ′ of the display panels and are made electrical connecting to each other by using an FPC having flexibility while the common electrodes and ′ are made electrical connecting by an FPC. Voltage drive circuits each consisting of a single system is provided, which supply a voltage to respective electrodes and ′ via the FPCs and
