Claim:
1. A three-dimensional display device which is a three-dimensional display device of a parallax barrier system including a liquid crystal display device of an IPS system having a TFT substrate and an opposed substrate as well as a liquid crystal barrier panel of a TN system having a first substrate and a second substrate; wherein the opposed substrate of the liquid crystal display device and the second substrate of the liquid crystal barrier panel are opposedly arranged by interposing a polarizer; wherein the liquid crystal display device is a liquid crystal display device interposing a liquid crystal between the TFT substrate having a pixel configured by a common electrode having a slit above a pixel electrode configured in a planar shape and the opposed substrate having a black matrix; wherein the pixel is configured by a rectangular shape or a square shape, and configured between a scanning line extended in a first direction and aligned in a second direction and an image signal line extended in the second direction and aligned in the first direction; wherein the TFT substrate includes a first pixel in which an angle made by an alignment axis of the TFT substrate and a direction of a long axis of a slit of the first pixel is θ1 and a second pixel in which an angle made by the alignment axis of the TFT substrate and a direction of a long axis of a slit of the second pixel is θ2; wherein the θ1 and the θ2 are in a relationship of θ1=−θ2; wherein the first pixel and the second pixel are arranged to switch in the first direction, and arranged to switch in the second direction; and wherein the alignment axis of the TFT substrate and an alignment axis of the second substrate of the liquid crystal barrier panel coincide with each other or are orthogonal to each other.
