Abstract:
An active-matrix liquid crystal display comprising:a plurality of pixel electrodes forming a matrix on a first substrate and a plurality of first thin film transistors formed to be connected to said corresponding pixel electrodes and their electrode wiring on the first substrate, wherein:display is performed by driving a liquid crystal layer sandwiched between the plurality of pixel electrodes formed on said first substrate and a common electrode formed on a second substrate placed opposite said first substrate,poly silicon thin film transistors using a poly silicon layer as an active layer is used as said first thin film transistors,the initial alignment of each liquid crystal molecule in said liquid crystal layer is controlled so that it will be substantially perpendicular to said pixel electrodes, andat least one material used in said liquid crystal layer has the molecular structure given by the following chemical formulas (1)-(6) is selected:Chemical formula (1) ##STR7## Chemical formula (2) ##STR8## Chemical formula (3) ##STR9## Chemical formula (4) ##STR10## Chemical formula (5) ##STR11## Chemical formula (6) ##STR12## wherein R and R' are suitable functional groups.
