LIQUID-CRYSTAL DISPLAY DEVICE WITH VIEWING ANGLE ADJUSTMENT FUNCTION

摘要

The present invention relates to a liquid-crystal display device capable of preventing the exposure of important information while also preventing a deterioration in resolution and permeability without the need for a separate electrode and a separate pixel for viewing angle adjustment. The liquid-crystal display device includes: first and second substrates; and a liquid-crystal layer interposed between the first and second substrates. When operated in a normal mode, liquid-crystal molecules of a first pixel (Pa) and a second pixel (Pb) adjacent to the first pixel are re-arranged in a horizontal direction. When operated in a privacy mode, in an Nth frame (N) the liquid-crystal molecules of the first pixel (Pa) are re-arranged in a horizontal direction, the liquid-crystal molecules located outside the second pixel (Pb) are re-arranged in a vertical direction and the liquid-crystal molecules in the center are re-arranged while forming a tilt angle in a vertical direction, in an Nth +1 frame (N+1), inversely, the liquid-crystal molecules located outside the first pixel (Pa) are re-arranged in a vertical direction and the liquid-crystal molecules located in the center are re-arranged to form a tilt angle in a vertical direction, and the liquid-crystal molecules of the second pixel (Pb) are re-arranged in a horizontal direction, thus re-arranging the liquid-crystal molecules of the first pixel (Pa) and the second pixel (Pb) in a horizontal direction in every frame, or alternately performing operations of re-arranging the liquid-crystal molecules located outside the pixels in a vertical direction and re-arranging the liquid-crystal molecules located in the center in a vertical direction to form a tilt angle.;COPYRIGHT KIPO 2020
