Problems solved by technology

However, the height of the gap in this type of panel is uneven, so it will affect the quality of the panel display
There is also a liquid crystal display panel that uses photo spacers and scattered spacers at the same time. The problem of color unevenness is overcome by the characteristics of the scattering spacers, but the scattering spacers are easy to cause light leakage. , which not only reduces the contrast, but also tends to cause the accumulation of spacers or scratches on the alignment film
In addition, each pixel in the panel is directly divided independently, so that the liquid crystal molecules cannot be penetrated as a whole, so as to reduce the pressure difference between the upper and lower parts of the panel, but it leads to poor liquid crystal diffusivity and subsequent processing technology problems.

Abstract

The invention discloses a liquid crystal panel and the manufacture method that includes the following steps: forming plural clearance material between the upper base board and the down base board, and some clearance material containing a flute, adding adhering agent into the flute and concreting to combine the up and down base board. the invention could not only keep the homogeneity of the clearance of display area in liquid crystal panel and avoid pollute liquid crystal molecule, but also improve the color odds phenomenon influenced by gravitation and prolong useful life.

Description

technical field [0001] The invention relates to a liquid crystal display panel, especially a method for manufacturing a liquid crystal display panel. Background technique [0002] Most of the current liquid crystal displays are vertically placed on desktops or platforms. However, the liquid crystal molecules filled in the panel are exposed to external heat sources, such as: backlight. Due to the influence of thermal expansion and gravity, the liquid crystal molecules are likely to flow towards the bottom of the panel, resulting in the increase of the gap under the liquid crystal display panel and resulting in uneven colors. The phenomenon. Furthermore, the current manufacturing technology still cannot make the height of the gaps in the panel uniform, and the amount of liquid crystal dripped is not easy to control, so the bottom of the panel is more prone to color unevenness. In addition, the demand for displays in the future is still developing toward large-area displays, ...
