Multi Domain Vertical Alignment Liquid Crystal Display with High Transmittance and Wide Viewing Angle

摘要

The present invention relates to a liquid crystal display device which improves transmittance by using a uniaxial film having different optical axis, phase retardation value and refractive index value according to a wavelength disposed between a vertically aligned liquid crystal layer and a top plate polarizer, A liquid crystal layer vertically aligned, and an upper plate polarizer. The optical axis of the liquid crystal in the liquid crystal layer is perpendicular to the substrate, and the liquid crystal display is vertically aligned. The transmission axis of the lower plate polarizer and the transmission axis of the upper plate polarizer are orthogonal to each other and the first positive A plate, the second positive A plate, the negative? / B plate, and the second positive A plate are arranged between the lower plate polarizer and the upper plate polarizer, 4 A-plate, a negative C-plate, a liquid crystal layer, a positive λ / 4 A-plate, a third negative A-plate and a fourth negative A- The optical axis of the gripping piece capacitive A- plate, the two adjacent sheets of the negative A- plate is perpendicular to each other.
