Abstract

　本発明による液晶表示装置は、第１、第２副画素ＳＰ－Ａ、ＳＰ－Ｂを含む画素を備えている。第１副画素ＳＰ－Ａの液晶層における液晶分子の基準配向方位は、第３、第４基準配向方位を有することなく、第１、第２基準配向方位を有しており、第２副画素ＳＰ－Ｂの液晶層における液晶分子の基準配向方位は、第１、第２基準配向方位を有することなく、第３、第４基準配向方位を有している。ある垂直走査期間において、第１副画素ＳＰ－Ａの液晶層に印加される実効電圧の絶対値は第２副画素ＳＰ－Ｂの液晶層に印加される実効電圧の絶対値よりも高く、別の垂直走査期間において、第２副画素ＳＰ－Ｂの液晶層に印加される実効電圧の絶対値は第１副画素ＳＰ－Ａの液晶層に印加される実効電圧の絶対値よりも高い。
