FIELD: physics.
SUBSTANCE: in a case where each of R, G and B pixels continuously display identical gray scales (1023 gray scale) in a liquid crystal display device in which thickness of liquid crystal layers for R pixel > G pixel > B pixel, the R pixel is alternately supplied with a positive signal potential (SHR1023) and a negative signal potential (SLR1023), the G pixel is alternately supplied with a positive signal potential (SHG1023) and a negative signal potential (SLG1023), and the B pixel is alternately supplied with a positive signal potential (SHB1023) and a negative signal potential (SLB1023). A first middle value (SMR1023) that is a middle value of SHR1023 and SLR1023 is set higher than a second middle value (SMG1023) that is a middle value of SHG1023 and SLG1023, which second middle value (SMG1023) is set higher than a third middle value (SMB1023) that is a middle value of SHB1023 and SLB1023.
EFFECT: compensating difference in feed-through voltage between the R, G and B pixels, thereby eliminating the problem of image sticking.
