Liquid crystal display device
摘要:
A VA-mode liquid crystal display device having a high display quality is provided. A liquid crystal display device according to the present invention includes a vertical alignment type liquid crystal layer; a first substrate and a second substrate facing each other with the liquid crystal layer interposed therebetween; a first electrode provided in the first substrate on the liquid crystal layer side and a second electrode provided in the second substrate on the liquid crystal layer side; and a first alignment film provided between the first electrode and the liquid crystal layer and a second alignment film provided between the second electrode and the liquid crystal layer. The liquid crystal display device includes a plurality of pixel areas located in a matrix. Each of the plurality of pixel areas includes a first liquid crystal domain in which a tilt direction of liquid crystal molecules at the center and in the vicinity thereof in a layer plane and in a thickness direction of the liquid crystal layer when a voltage is applied between the first electrode and the second electrode is a predetermined first direction, a second liquid crystal domain in which such a tilt direction is a predetermined second direction, a third liquid crystal domain in which such a tilt direction is predetermined third direction and a fourth liquid crystal domain in which such a tilt direction is a predetermined fourth direction; a difference between any two among the first direction, the second direction, the third direction and the fourth direction is approximately equal to an integral multiple of 90 degrees.
