The following conditions: 0.1≤Q/P≤100 can be met with the numerical value of the second width Q.
In embodiment, need that first both alignment layers fluent material is coated on first substrate 100 when making the first both alignment layers 400
Afterwards, it then is toasted and the first both alignment layers 400 is made, and the stereochemical structure (e.g. spacer) on first substrate 100 may
It will cause coating liquid to be stranded on the surface of stereochemical structure and generate surface tension phenomena, and then may cause coating liquid
The thickness extension of film layer is uneven.The embodiment of content according to the present invention, when the first width P and the second width Q of spacer 800 are full
The condition of above-mentioned 0.1≤Q/P≤100 of foot and the spacing of spacer 800 meet be greater than or equal to 25 microns (μm) and be less than or
When equal to 500 microns (μm), indicate that the ratio limitations of two width of the shape of spacer 800 within the above range, then can be with
It reduces surface tension and improves the stereochemical structure of spacer 800 for being coated with the thickness extension uneven phenomenon of liquid, thus can be with
The thickness uniformity of first both alignment layers 400 made of improving, and display quality is improved in turn.Spacer 800 as shown in Figure 2 A
Shape be by perpendicular to substrate overlook direction observation, the plan view shape for the spacer 800 seen.
In one embodiment, as shown in Figure 1A and Fig. 2A, peripheral region 120 can have a first area 121, first area 121
It is defined as extending from the boundary 100A of viewing area 110 and peripheral region 120 to the direction of frame glue 700 100 microns of range.Such as figure
Shown in 1A and Fig. 2A, first area 121 is covered from 110 outside of viewing area (namely boundary 100A) extends 100 microns outward
Range, and around viewing area 110.
In embodiment, the spacer 800 in first area 121 is, for example, electrically conductive barrier (conductive
Stopper), to prevent the conductive structure of about 800 two sides of spacer from short circuit occurs, while and support effect is provided.However,
The above are an embodiment, the spacer 800 in the first area 121 of the content of present invention is not limited to electrically conductive barrier.
In embodiment, as shown in Figure 2 A, the unit of the first width P and the second width Q are micron (μm), are located at first area
The numerical value of the first width P and the second width Q of spacer 800 in 121 meet the following conditions: 0≤P/Q≤1.Some embodiments
In, the unit of the first width P and the second width Q are micron (μm), and first of the spacer 800 in first area 121 is wide
The numerical value for spending P and the second width Q can further satisfaction the following conditions: 0.01≤P/Q≤1.
As previously mentioned, need for both alignment layers fluent material to be coated on first substrate 100 when the first both alignment layers 400 of production,
And being coated with the surface tension phenomena that liquid is stranded on the surface of stereochemical structure (e.g. spacer) and generates may lead
Cause the thickness extension of coating liquid film layer uneven, as shown in Figure 2 A, since first area 121 is closest in viewing area 110
Region, when the applied amount for being coated with liquid is fixed, if the capillary phenomenon that the stereochemical structure in first area 121 generates causes this
Coating liquid levels in region unpredictably increase and more coating liquid are caused to be trapped in first area 121, will necessarily
It causes the amount of the coating liquid in the viewing area 110 of neighbouring first area 121 to reduce, in turn results in the coating in viewing area 110
Liquid film layer unpredictably declines；In this way, which then the first both alignment layers 400 not only in peripheral region 120 have uneven thickness
The problem of problem, the first both alignment layers 400 in viewing area 110 also have uneven thickness.
In contrast, the embodiment of content according to the present invention, as the first width P of the spacer 800 in first area 121
When meeting the condition of 0≤P/Q≤1 with the numerical value of the second width Q, even the condition of further satisfaction 0.01≤P/Q≤1 when,
Then the shape of the spacer 800 in first area 121 is close to round (as shown in Figure 2 A), due to surface tension of liquid size with
Liquid level and the contact length of stereochemical structure are inversely proportional, thus the spacer 800 for meeting above-mentioned condition can be with relatively large
Bearing area (the namely sectional area 800a at the top of spacer 800, as referring to figure 1E) when simultaneously have it is relatively small
Liquid level contact length (the perimeter 800b of the sectional area 800a of spacer 800 namely as referring to figure 1E), and this lesser liquid
Face contact length can reduce the capillary phenomenon that coating liquid generates and improve the thickness extension unevenness of coating liquid film layer, and
The coating liquid being trapped in first area 121 is reduced, the reduction of the coating liquid in viewing area 110 can also be further decreased
It measures and maintains to preset the uniform coating liquid thickness having in viewing area 110.In this way, between in first area 121
The the first width P and the second width Q of gap 800 meet above-mentioned condition, then can achieve while improving viewing area 110 and the firstth area
The thickness uniformity of the first both alignment layers 400 in domain 121, reduces the generation of picture color spot (mura), and improves display device
Display quality.
In embodiment, the space D 1 between the spacer 800 in first area 121 is, for example, to be greater than or equal to 5
Micron and be less than or equal to 90 microns.Since the intensity of the distance between stereochemical structure size and capillary phenomenon is inversely proportional, according to
The embodiment of the content of present invention, the space D 1 between spacer 800 in first area 121 is relatively small, the shape of spacer 800
Shape is approximate circle, can achieve the capillary phenomenon and improve the thickness extension of coating liquid film layer not for reducing that coating liquid generates
, the effect of the thickness uniformity of the first both alignment layers 400 is improved.
In one embodiment, as shown in Figure 1A and Fig. 2A, peripheral region 120 can more have a second area 123, second area
123 systems are defined as rising from the 100A of boundary 100 microns to the direction of frame glue 700 and extend to 800 at the 100A of boundary
The range of micron.In other words, second area 123, which is covered from the outside of first area 121, extends 700 toward the direction of frame glue 700
The range of micron, and around viewing area 110 and first area 121.
In embodiment, the spacer 800 in second area 123 is, for example, spacing supporting layer (gapsupport), is used
To provide support effect.However, the spacer 800 in the second area 123 of the content of present invention not limits the above are an embodiment
In spacing supporting layer.
In embodiment, as shown in Figure 2 A, a distance B of the spacer 800 and boundary 100A in second area 123 is micro-
Rice (it is typical example that one of spacer 800 is only indicated in attached drawing with B microns of boundary 100A distance), the first width P, second
The unit of width Q and distance B be micron (μm), and the first width P, the second width Q and distance B numerical value (no unit) meet with
Lower condition: P/Q≤(B-70)/30,100 < B≤800.
For example, when the first width P of spacer 800 and the second width Q are respectively 100 microns and 6 microns, P/Q
=16.67.If this gap 800 is placed in second area 123 with boundary 100A at for 161 microns, (B-70)/30
=(161-70)/30=3,3 not greater than or equal to 16.67, then according to an embodiment of the invention, this gap 800 is placed in
When distance B is at 161 microns, it is unable to reach the effect of this case, is likely to result in the bad shadow of 400 uneven thickness of the first both alignment layers
It rings.For example, if when above-mentioned spacer 800 is placed in second area 123 with boundary 100A at for 600 microns,
(B-70)/30=(600-70)/30=17.7,17.7 are greater than 16.67, then according to an embodiment of the invention, this gap 800 is put
Be placed in distance B be 600 microns at when, then can reach the support effect of spacer 800 simultaneously, and the first orientation can also be maintained
The thickness uniformity of layer 400.In other words, it can be seen that P/Q≤(B-70)/30 condition for adjusting from two above-mentioned examples
Relativeness between the shape (P/Q) and its setting position (distance B) of whole spacer 800 provides the principle of design, and makes
Above-mentioned condition must be met can reach the support effect of offer spacer 800 simultaneously, and maintain the thickness of the first both alignment layers 400 equal
Even property.
In embodiment, the space D 2 between the spacer 800 in second area 123 is, for example, to be greater than or equal to 5
Micron and be less than or equal to 600 microns.
In one embodiment, as shown in Figure 1A, peripheral region 120 can more have a third region 125, and 125 system of third region is fixed
Justice is that the range of frame glue 700 is extended to from the outside of second area 123.In other words, third region 125 is covered from second area
123 outside extends to the range of frame glue 700, and around viewing area 110, first area 121 and second area 123.
In embodiment, the spacer 800 in third region 125 is, for example, liquid barrier layer (liquidsupport),
To stop both alignment layers to be coated with the region except liquid flooding to frame glue 700.However, the above are an embodiment, the content of present invention
Third region 125 in spacer 800 be not limited to liquid barrier layer.Of spacer 800 in third region 125
Spacing between one width P and the second width Q and spacer 800 can need not then meet aforementioned first area 121 and/or
Condition described in two regions 123.
