The support column 14 of post 13 and second is typically also formed in viewing area, for, into after box, being maintained in first substrate 10 and second substrate 20
The thickness of display panel.And planarization layer 12 may be generally formed on whole first substrate 10, to cover color film layer 11 and
One substrate 10.Now, can corresponding to the opening position of the first support column 13 as shown in figure 1, on the planarization layer positioned at viewing area
With formed with the first hole slot 121, so that the upper surface of the first support column 13 is less than second to the first distance H1 of first substrate 10
The upper surface of support column 14 to first substrate 10 second distance H2.It is understood that due on planarization layer 12 formed with
First hole slot 121, so when making the film layer for forming the first support column 13 and the second support column 14 on planarization layer, should
Film layer can form depression in the opening position of corresponding first hole slot 121, so as to form difference in height.Now, first is formed in film layer
, can be different to form relative altitude after being patterned processing using common mask plate when support column and the second support column

The present embodiment some alternatively in implementation, the first support column can have identical with the second support column
Highly (i.e. the distance of the upper surface of support column to lower surface).As shown in Figure 2 a, due to the height h1 of the first support column 13 and
The height h2 of two support columns 14 is identical, so the depth h3 by controlling the first hole slot 121, it is possible to realize relative between the two
In the difference in height h4 of first substrate 10.Herein, identical highly refer generally to height theoretical value it is identical.In actual manufacturing process
In, there may be certain error between the actual value and theoretical value of height.In application scenes, due to for forming the
The solution of one support column and the second support column has mobility, is easily flowed to the first hole slot on planarization layer, so as to cause
The height h1 of the first support column eventually formed may be more than the height h2 of the second support column, while difference in height between the two
H4 can also have certain error.
Alternatively, in order to realize the first support column and the second support column on the first substrate it is shown go out overall size it is equal
It is even, so as to optimize display effect, improve Consumer's Experience.Orthographic projection of first support column to first substrate and the second support column are to the
The orthographic projection of one substrate can have identical area.Further, orthographic projection of first support column to first substrate and second
Orthographic projection of the support column to first substrate can also be of similar shape.Fig. 2 b are may refer to, it illustrates aobvious shown in Fig. 1

The closing raceway groove of setting.Further, since the second hole slot 122 is located at non-display area, shadow will not be caused to the viewing area of display panel
Ring, so in order to reduce manufacturing technique requirent and difficulty, improve production efficiency, the aperture of the second hole slot 122 can be more than first
The aperture of hole slot 121.And the depth of the second hole slot 122 can be more than the depth of the first hole slot 121.As shown in figure 3, it can incite somebody to action
Second hole slot 122 is made as through-hole groove.Now, the making precision of the second hole slot 122 can often be less than the system of the first hole slot 121
Make precision, be advantageous to improve production efficiency.
It should be noted that because the first hole slot 121 and the second hole slot 122 are along parallel to cutting on first substrate direction
Face shape can be variously-shaped, therefore for different cross sectional shapes, the definition in its aperture is also different.As described in Figure 4,
When the second hole slot 122 is raceway groove, its aperture can be the width L of raceway groove.As an example, as shown in Figure 5 a, work as cross sectional shape
For ellipse when, its aperture can be major axis size L.As shown in Figure 5 b, when cross sectional shape is pentagon, its aperture can be with
For the distance between summit and opposite side L.Again as shown in Figure 5 c, when cross sectional shape is octagon, its aperture can be two phases
The distance between opposite side L.
