Abstract:
1. A liquid crystal display device, comprising: upper and lower panels facing each other; a first field generating electrode formed on the lower panel; a second field generating electrode formed on the lower panel and disposed alternately with the first field generating electrode to generate a horizontal electric field; a liquid crystal layer interposed between the upper and the lower panels and comprising liquid crystals; upper and lower polarizer assemblies disposed on outer surfaces of the upper and lower panels; and a retardation film interposed between either the upper panel and the upper polarizer assembly or between the lower panel and the lower polarizer assembly, wherein the retardation film ranges from about 20 nm to about 100 nm in retardation value, wherein the retardation film is a quasi A-plate compensation film, and the quasi A-plate compensation film has refractive anisotropy of nx−ny>ny−nz, where nx, ny and nz are refractive indices along x, y and z axes, respectively.
