Description
Technical field
The invention belongs to liquid crystal display device field more particularly to a kind of liquid crystal display spacer and its manufacturers
Method.
Background technology
Currently, liquid crystal display panel is widely used, liquid crystal display by be oppositely arranged color membrane substrates, array substrate
And the liquid crystal being clipped between two substrates is constituted.In order to keep gap uniformity between color membrane substrates and array substrate and constant,
Spacer (spacer) is equipped with usually between two substrates.Fig. 1 is prior art color membrane substrates side spacer distribution schematic diagram,
Middle R, G, B respectively represent RGB color blocking, and RGB color blocking can be known as open region 20 with transmitted light.Spacer 10 is away from open region
20 distance is d, when spacer 10 is closer apart from open region 20, can lead to liquid crystal molecular orientation near spacer 10 not
It is good, light leakage can occur around spacer 10, lead to the reduction of liquid crystal display contrast, influence the display product of liquid crystal display
Matter.In order to avoid such case, distance d of the spacer 10 away from open region 20 can only be increased, i.e., in the case where aperture opening ratio is constant,
The bottom area that spacer need to be reduced, since existing spacer is all trapezoidal, spacer can be made by reducing spacer bottom area
Attenuate, support and recovery capacity reduce, to ensure box thickness.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of liquid crystal display spacer, and liquid crystal display includes opposite
The array substrate and color membrane substrates of setting, and the spacer between array substrate and color membrane substrates, the spacer
It is made of inorganic material layer and the organic resin layer above inorganic material layer, and the cross-sectional area at spacer both ends is less than it
The section shape of intermediate cross-sectional area, spacer is in mushroom broad in the middle small in ends.Inorganic material layer be silica or
Silicon nitride.
The present invention also provides a kind of manufacturing methods of liquid crystal display spacer, include the following steps：The first step, in glass
Black matrix" is formed on glass substrate；Second step forms color blocking layer on the glass substrate for formed black matrix"；Third walks,
Transparent electrode layer is formed on the glass substrate for formed color blocking layer；4th step, in the glass for having formed transparent electrode layer
Substrate is respectively formed inorganic material layer and organic resin layer；5th step is exposed development solidification to organic resin layer；6th
Step carries out dry etching to inorganic material layer, and dry etching to transparent electrode layer forms spacer.The transparent electrode layer be ITO,
IGZO or ZnO.
Advantageous effect：The present invention forms two by the way that inorganic material layer is arranged below organic resin layer, using dry carving technology
Small spacer broad in the middle is held, to enhance the enabling capabilities of spacer, ensures that box thickness is stablized.

Specific implementation mode
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate
It the present invention rather than limits the scope of the invention, after having read the present invention, those skilled in the art are to of the invention various
The modification of equivalent form falls within the application range as defined in the appended claims.
Liquid crystal display is made of color membrane substrates, array substrate and the liquid crystal that is clipped between two substrates being oppositely arranged.
In order to keep gap uniformity between color membrane substrates and array substrate and constant, spacer is equipped with usually between two substrates
(spacer), the manufacture of spacer carries out usually on color membrane substrates.The present invention provide a kind of liquid crystal display spacer and
Its manufacturing method, specifically comprises the following steps：First, black matrix" (BM) 40, black are formed on transparent glass substrate 30
Matrix 40 is to shading, as shown in Figure 2；Secondly, color blocking layer 50 is formed on the glass substrate for having formed black matrix" 40, such as
Shown in Fig. 3, color blocking layer 50 can be that R (red), G (green), B (indigo plant) or other colors, the number of color blocking layer 50 are also not limited to 3
Kind, color blocking layer 50 is separated from each other by black matrix" 40；Again, transparent electricity is formed on the glass substrate for having formed color blocking layer 50
Pole layer 60, as shown in figure 4, the material of transparent electrode layer 60 is ITO, IGZO or ZnO；Then, transparent electrode is being formed
The glass substrate of layer 60 is respectively formed inorganic material layer 70 and organic resin layer 80, has as shown in figure 5, inorganic material layer 70 is located at
The lower section of machine resin layer 80, the wherein material of inorganic material layer 70 can be silica or silicon nitride；Then, have to upper layer
Machine resin layer 80 is exposed development solidification, obtains similar trapezoidal spacer 90 as shown in FIG. 6；Finally, to the nothing of lower layer
Machine material layer 70 carries out dry etching, dry etching to transparent electrode layer 60, since the transparent electrode dry etching as ITO can not carry out it
Etching, in this way, inorganic material layer 70 can etch inwardly, the plasma of reflection can bang 80 lower section of organic resin layer
It hits, so that the cross-sectional area at 100 both ends of finally formed spacer is less than in-between cross-sectional area, the section of spacer 100 is in
The lower layer of mushroom shaped broad in the middle small in ends, spacer as shown in Figure 7 is inorganic material layer, and upper layer is organic resin layer, is led to
The shape of spacer can be optimized by overregulating the dry carving technology of inorganic material layer.
The present invention is formed small in ends broad in the middle by the way that inorganic material layer is arranged below organic resin layer using dry carving technology
Spacer ensure that box thickness is stablized to enhance the enabling capabilities of spacer.
