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 of all, the basic structure of the present invention is as image 3 shown. The AS-NOOC liquid crystal display of the present invention includes: a first substrate 31 and a second substrate 32 opposite to...

A lateral electric field liquid crystal display, comprising: a first substrate, a second substrate, a liquid crystal layer, which is sandwiched between the first substrate and the second substrate, several gate lines and several data lines, which are arranged on the On the first substrate, and interlaced with each other to surround and form a pixel area and a pixel electrode, which are arranged on the first substrate and located in the pixel area; the lateral electric field liquid crystal display also includes: a pair of opposite electrodes configured On the second substrate, and corresponding to one of the data lines; a pair of protection electrodes, configured on the first substrate, wherein one of the data lines is located between the pair of protection electrodes; a shared electrode, with a first A part and a second part are disposed on the first substrate, wherein the first part has a first slit corresponding to one of the data lines, the second part is located in the pixel area and adjacent to the pixel electrode. The invention has the advantages of high aperture ratio and low manufacturing cost.
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...
