Active matrix reflective guest-host LCD with pixel electrodes patterned on quarter wave plate

摘要

A reflective guest-host liquid-crystal display includes: a pair of upper and lower substrates joined together with a predetermined space therebetween; and a guest-host liquid-crystal layer which is held within the space and contains a dichroic dye. The upper substrate is provided with at least a counter electrode. At least thin-film transistors (TFTs), a reflective layer, a &lgr;/4 phase shifter (quarter- wavelength plate), and pixel electrodes are formed on the lower substrate. The . lambda./4 phase shifter is formed above the TFTs and the reflective layer, and has contact holes connecting to the drain electrodes of the TFTs. The pixel electrodes are patterned on the &lgr;/4 phase shifter and connected to the corresponding drain electrodes of the TFTs through the corresponding contact holes.
