Abstract
The invention provides a spacer for a liquid crystal display and a manufacturing method of the spacer. The liquid crystal display comprises an array substrate, a color film substrate and the spacer located between the array substrate and the color film substrate, the array substrate and the color film substrate are oppositely arranged, and the spacer is composed of an inorganic material layer and an organic resin layer located on the inorganic material layer. The cross sectional area of the two ends of the spacer is smaller than that of the middle of the spacer. The cross section of the spacer is in the shape of a mushroom with the two ends small and the middle large. According to the spacer, due to the fact that the inorganic material layer is located below the organic resin layer, the spacer with the two ends small and the middle large is formed through the dry etching technology, and therefore the supporting capacity of the spacer is enhanced, and it is guaranteed that the box thickness is stable.
Description
Technical field
The invention belongs to liquid crystal display device field, particularly relate to a kind of liquid crystal display sept and manufacture method thereof.
Background technology
At present, liquid crystal panel is widely used, and liquid crystal display is made up of the color membrane substrates be oppositely arranged, array base palte and the liquid crystal be clipped between two substrates.In order to keep the gap uniformity between color membrane substrates and array base palte and constant, between two substrates, be usually provided with sept (spacer).Fig. 1 is prior art color membrane substrates side sept distribution schematic diagram, and wherein R, G, B represent RGB color blocking respectively, and RGB color blocking can be called open region 20 by transmitted light.Sept 10 is d apart from the distance of open region 20, when sept 10 is nearer apart from open region 20, the liquid crystal molecular orientation near sept 10 can be caused bad, light leak can occur around sept 10, cause liquid crystal display contrast to reduce, affect the display quality of liquid crystal display.In order to avoid this situation, the distance d of sept 10 apart from open region 20 can only be increased, namely when aperture opening ratio is constant, the area of going to the bottom of sept need be reduced, because existing sept is all trapezoidal, reducing sept area of going to the bottom can make sept attenuate, and supports and recovery capacity reduction, thus cannot ensure that box is thick.
Summary of the invention
In order to solve the problem, the invention provides a kind of liquid crystal display sept, liquid crystal display comprises the array base palte and color membrane substrates that are oppositely arranged, and the sept between array base palte and color membrane substrates, described sept is made up of inorganic material layer and the organic resin layer be positioned at above inorganic material layer, and the cross-sectional area at sept two ends is less than the cross-sectional area in the middle of it, the section shape of sept is mushroom broad in the middle small in ends.Inorganic material layer is monox or silicon nitride.
The present invention also provides a kind of manufacture method of liquid crystal display sept, comprises the steps: the first step, forms black matrix" on the glass substrate; Second step, the glass substrate forming black matrix" is formed color blocking layer; 3rd step, the glass substrate forming color blocking layer forms transparent electrode layer; 4th step, forms inorganic material layer and organic resin layer respectively at the glass substrate forming transparent electrode layer; 5th step, carries out exposure imaging solidification to organic resin layer; 6th step, carries out dry quarter to inorganic material layer, and dry quarter, to transparent electrode layer, forms sept.Described transparent electrode layer is ITO, IGZO or ZnO.
Beneficial effect: the present invention, by arranging inorganic material layer below organic resin layer, utilizes dry carving technology to form sept broad in the middle small in ends, thus enhances the supporting capacity of sept, ensures that box is thick stable.
