Abstract: This invention relates to a transflective liquid crystal display device (11, 21), comprising a plurality of pixels, each comprising a liquid crystal layer (12, 22), being sandwiched between front and back electrode means (13, 23; 14, 24) as well as front and back polarizer means (17a, 27a; 17b, 27b). Said display device is characterized in that an optical ?/4 layer (16a, 26a) at least partly is arranged between said front polarizer (17a, 27a) and said liquid crystal layer (12, 22), and said liquid crystal layer (12, 22) is a liquid crystal layer having a twist angle essentially within a range ±80-100°, such as 90°. The invention further relates to methods for generating a quarterwave foil for use in a liquid crystal display as defined above.

Abstract: In a vertical aligned LCD the other substrate has further protrusion parts e.g. parallel to the gate buses or source buses, in addition to the protrusion parts parallel to slits of pixel electrodes. By the further protrusion, when a voltage is applied to the liquid crystal layer, it becomes easy to align axes of liquid crystal molecules in one direction, so that transmittivity of light which travels through liquid crystal panel becomes high.

Abstract: The effect of twisting motion of LC molecules in multi-domain pixels of vertically aligned nematic LCDs, which leads to image retention, is reduced by applying a reset pulse which reduces the LCD voltage to below threshold. Several methods of reset (multiple counter electrodes, reset from column drivers, direct block reset, reset via storage capacitor line) are possible.
