Abstract
In an FFS liquid crystal display device, viewing angle characteristics are further improved. In an FFS liquid crystal display device, the alignment axis of a first alignment film of a first substrate and the alignment axis of a second alignment film of a second substrate are directed in the same direction. At least two of an upper polarizer, a lower polarizer, or a retardation platesatisfy conditions below. (1) The absorption axis of the upper polarizer forms an angle of one to 45 degrees inclusive with the alignment axis. (2) The absorption axis of the lower polarizer forms an angle of 91 to 135 degrees inclusive or forms an angle of 45 to 89 degrees inclusive with the alignment axis. (3) The extension axis of the retardation plateforms an angle of one to 45 degrees inclusive with the alignment axis.
