Abstract:
A liquid crystal display comprising:a first substrate comprising a first surface; a second substrate comprising a second surface, the second surface being in parallel with and opposite to the first surface of the first substrate, and a pixel area being defined on the second surface; a first electrode positioned on the first surface of the first substrate; a pixel electrode positioned on the pixel area of the second substrate, the pixel electrode having a first slit positioned along a first direction; and a plurality of anisotropic liquid crystal molecules with negative dielectric constant positioned between the first electrode and the pixel electrode, the longitudinal axis of the liquid crystal molecules being positioned along a second direction horizontally, and paralleled to the first electrode and the pixel electrode, a first angle being formed between the second direction and the first direction; wherein when a voltage is applied between the first electrode and the pixel electrode, a biased electrical field is formed between the first electrode and the pixel electrode, such that (a) a first horizontal biased electric field is formed in the neighborhood of the first slit, and the first horizontal biased electric field is perpendicular to the first direction to rotate the liquid crystal molecules and make the longitudinal axis of the liquid crystal molecules in the neighborhood of the first slit rotate in parallel to the first direction, (b) the longitudinal axis of the liquid crystal molecules in the neighborhood of the first electrode maintain along the second direction because no horizontal biased electrical field is formed near the first electrode, and (c) the liquid crystal molecules between the first electrode and the first slit gradually rotate from the second direction to the first direction.
