Abstract
The liquid crystal display panel comprising a twisted nematic liquid crystal inserted between a pair of substrates having alignment films, respectively. The liquid crystal twists from one substrate to the other substrate at a predetermined twist angle which is greater than zero degrees but smaller than 90 degrees. A polarizer and an analyzer are arranged crosswise. The alignment films are divided into minute regions so that the liquid crystal molecules in one of the regions align in one direction and the liquid crystal molecules in the other region align in another direction. The product (.DELTA.nd) of the anisotropy of the refractive index (.DELTA.n) and the layer thickness (d) of the liquid crystal is smaller than approximately 0.5 .mu.m and ensures a linearly polarized light incident onto the liquid crystal rotates approximately 90 degrees before the light emerges from the liquid crystal.
