containing at least one compound selected from a group of compounds
represented by formula (1) as a first component, at least one compound
selected from a group of compounds represented by formula (2) as a second
component, at least one compound selected from a group of compounds
represented by formula (3) as a third component, and at least one
compound selected from a group of compounds represented by formula (4) as
a fourth component: ##STR00001## wherein the liquid crystal composition
consists essentially of the first component, the second component, the
third component and the fourth component and wherein R.sup.1 is alkyl or
