Vertically-aligned (VA) liquid crystal display device

TL;DR: In this article, a vertically alignment mode liquid crystal display device having an improved viewing angle characteristic is disclosed, which uses a liquid crystal having a negative anisotropic dielectric constant, and orientations of the liquid crystal are vertical to substrates when no voltage being applied, almost horizontal when a predetermined voltage was applied, and oblique when an intermediate voltage is applied.
Patent

Domain divided liquid crystal display device with particular pretilt angles and directions in each domain

TL;DR: In this paper, a liquid crystal display device comprising different liquid crystal aligning domains in each of a plurality of unit regions for improving a characteristic of a viewing angle is presented, where molecules of the liquid crystal located intermediately between the first and second plates rise in accordance with the first pretilt angle when voltage is applied.
Patent

Liquid crystal display device and thin film transistor substrate

TL;DR: In this paper, a vertically aligned liquid crystal display device for controlling liquid crystal molecules alignment in voltage application by providing linear structures or linear slits consisting of a plurality of constituent units to at least one of a pair of substrates having an electrode thereon is presented.
Patent

Liquid crystal display apparatus having wide transparent electrode and stripe electrodes

TL;DR: In this paper, a liquid crystal is arranged between a pair of substrates, and an oblique electric field is formed between the stripe electrodes and the transparent electrode, so that the liquid crystal molecules are aligned along the oblique field.
Patent

Liquid crystal display device and method of preventing image sticking thereon

TL;DR: In this article, a sub picture element electrode directly connected to a thin film transistor is disposed between a floating sub-picture element electrode capacitively coupled to a control electrode and a gate bus line in order to prevent injection of electric charges from the gate bus lines to the floating sub pictures element electrode.
