Abstract

A liquid crystal display device comprises: a first liquid crystal cell being a lateral electric field driven type; a second liquid crystal cell being a lateral electric field driven type; a first polarizing plate and a second polarizing plate, which are disposed so as to sandwich the first liquid crystal cell; and a third polarizing plate and a fourth polarizing plate, which are disposed so as to sandwich the second liquid crystal cell. The liquid crystal display device is configured such that rotation of a liquid crystal molecule of the first liquid crystal cell and rotation of a liquid crystal molecule of the second liquid crystal cell cancel and compensate for a hue change of the first liquid crystal cell or the second liquid crystal cell when viewed from a predetermined direction.
