Embodiment Construction
[0047]The inventors found that the liquid crystal display panels using the prior art have defects such as edge mura, cold bubbles, black clusters, and point-like unevenness (trace mura). After research, it is found that the cause of the defect is the height of the photo spacer formed on the surface of the color filter in the display area of the first substrate and the photo spacer formed between the periphery of the display area of the first substrate and the sealant. There is only one kind of height, which does not take into account that the height of the photo-spacer changes with the external environment, which may bring about the above defects. In the present invention, a first optical spacer with a first height and a second optical spacer with a second height are formed in the display area of the first substrate, and a third optical spacer is formed between the inner side of the sealant and the periphery of the display area.

Abstract
The invention provides a liquid crystal display panel, comprising a first substrate, a liquid crystal layer, a frame glue and a second substrate, wherein the first substrate is arranged oppositely to the second substrate; the frame glue bonds the first substrate with the second substrate to form a display area; the liquid crystal layer is positioned in the display area; the frame glue is positioned at a periphery of the display area and is provided with an inner side and an outer side; the inner side is one side facing to the display area; the outer side is one side far away from the display area; the display area is provided with a first optical spacer and a second optical spacer; the first optical spacer has a first height; the second optical spacer has a second height; the first height is greater than the second height; a third optical is arranged between the periphery of the display area and the inner side of the frame glue, and has a third height which is less than the first height. The invention also provides a method for manufacturing the liquid crystal display panel. The invention solves the defects of edge unevenness, cold bubble, block groups, trace unevenness and the like of the liquid crystal display panel, prevents the liquid crystal on the edge from being polluted by the frame glue, and saves the use quantity of the liquid crystal.
Description
technical field [0001] The invention relates to a liquid crystal display panel, in particular to a structure of a liquid crystal display panel with optical spacers of different heights and a manufacturing method of the liquid crystal display panel. Background technique [0002] With the development of optoelectronic and semiconductor technologies, flat panel displays have also matured. Among many flat-panel displays, thin film transistor liquid crystal display (TFT-LCD) has become the mainstream of the market due to its superior characteristics such as high image quality, thinness, low power consumption, and no radiation, and is widely used in TV, computer, mobile phone, notebook and other monitors. [0003] Generally, a liquid crystal display panel includes a first substrate (color filter upper substrate, CF) and a second substrate (array lower substrate). The display area between the first substrate and the second substrate is separated by a photo spacer to form a cell g...
