Embodiment Construction

[0043] The details and implementation of the present invention will be illustrated by the following preferred embodiments. It should be noted that the following preferred embodiments are only intended to illustrate the detailed content and implementation of the present invention so as to make it easier for people to understand, and are not intended to limit the present invention.

[0044] It provides a horizontal electric field liquid crystal display, also known as AS-NOOC (Advanced Super No Overcoat) liquid crystal display, which is based on the AS-IPS liquid crystal display for improvement, and through a special electrode arrangement, to Avoid the use of the overcoat layer to improve the aperture ratio, yield and manufacturing cost of the conventional AS-IPS.

[0045]First, the basic architecture of the present invention is shown in FIG. 3 . The AS-NOOC liquid crystal display of the present invention includes: a first substrate 31 and a second substrate 32 opposite to each ...

Abstract

A liquid crystal display with horizontal electric field consists of liquid crystal layer set between the first and the second base plates, a numbers of grid lines and data lines on the first base plate for forming a pixel region, pixel electrode on the first base plate in said pixel region, a face-opposite electrode on the second base plate in position corresponding to one of data lines, a pair of protection electrode on the first base plate as one data line set between this pair and a share electrode with two units being separately set near to pixel electrode and set in corresponding to one of data lines.

Description

【Technical field】 [0001] The present invention relates to an in-plane switching (In-Plane Switching, IPS) liquid crystal display (Liquid Crystal Display, LCD), in particular to a third-generation in-plane switching (Advanced Super Overcoat Layer) without a flat layer (Overcoat Layer). In-PlaneSwitching, AS-IPS) liquid crystal display. 【Background technique】 [0002] Liquid crystal displays are lighter than cathode ray tube (CRT) displays, take up less space and emit less radiation. They have various applications and are widely used in daily life. , become the mainstream of the display. Since its evolution, the picture quality of liquid crystal displays has even been comparable to that of traditional cathode ray tube displays. However, liquid crystal displays still have many disadvantages to be overcome, such as a narrow viewing angle and uneven brightness. [0003] Aiming at the problem of narrow viewing angle, several wide viewing angle technologies have been used to ove...
