Abstract
A novel liquid crystal display device is disclosed. The liquid crystal display device comprises a first polarizing film, a first retardation area with an Re of 70 to 330 nm and a value of Nz of not less than 0 to less than 0.5 and a slow axis perpendicular to a transmission axis of the first polarizing film; a second retardation region with an Re of not greater than 50 nm and an Rth of 10 to 140 nm; and a liquid crystal cell comprising a liquid crystal layer with a slow axis in a black state parallel to the transmission axis of the first polarizing film; and a second polarizing film in this order.
