Figure, dotted line frame shows the amplification position of partial enlarged drawing wherein in top view.Clearly to show the position of the contraposition mark 120
And shape, in Fig. 3 partial enlarged drawing, the transparence of covering layer 130 is shown.
In the present embodiment, the contraposition mark 120 is multiple, also, the multiple contraposition mark 120 is with each two one
The mode of group is arranged in the edge of the submounts 110.The covering layer 130 is also multiple, in the multiple covering layer 130
Each correspondence cover that one group (i.e. two) are described to align mark 120.It should be noted that the number of the contraposition mark 120
Amount, packet mode, the quantity of the covering layer 130 can be determined according to the actual requirements, be not limited to provide in the present embodiment
Mode, for example, the multiple contraposition mark 120 is arranged in submounts using quantity such as each or three or four as one group
110 edge.For another example the covering layer 130 can cover the multiple contraposition mark 120 in one-to-one mode
In each, or cover using the covering layer 130 the contraposition mark 120 of the other quantity such as three or four.
Contraposition mark 120 can be provided in the vacancy section on the edge of submounts 110, such as Fig. 2, the vacancy section
It is shaped as rectangle.The covering layer 130 for covering the rectangle vacancy section is shaped as rectangle, and the covering layer 130 is in submounts
It is non-transparent state on 110 so that the board unit is assembled into after LCM, was passed through originally at the contraposition mark 120
LCM backlights are blocked by the covering layer 130, so as to prevent light leakage phenomena.It is understood that the contraposition mark 120 can be with
It is other forms, such as clear area, it is used for the contraposition of ccd image sensor on cutting machine, even if the contraposition mark 120 is used
Vacancy section, its shape is also not necessarily limited to the other shapes such as rectangle or circle, annular, cross, hollow out cross, and
The shape of covering layer 130 is not limited, as long as the contraposition mark 120 can be covered.In the present embodiment, the covering layer 130
On a surface of the glass substrate 100, in alternate embodiments, the covering layer 130 is located at the glass base
On two apparent surfaces of plate 100.
Further, the contraposition mark 120 that the non-transparent material is made is, for example, red quinoid structure phenolphthalein, or
Vulcanized lead, silver sulfide of black etc..Certainly, the contraposition mark 120 can be made of other non-transparent materials, but in view of institute
The preparation process of board unit is stated, the quinoid structure phenolphthalein, vulcanized lead and silver sulfide are currently preferred material.
The cutting process of the board unit of the present embodiment is illustrated below in conjunction with Fig. 4 to Fig. 7, for convenience of description, with
It is lower will by taking the cutting between two submounts 110 adjacent on glass substrate 100 as an example illustrate, other adjacent submounts 110 it
Between cutting mode it is similar.
Such as Fig. 4, glass substrate is provided first, and it at least obtains two submounts 110 after cutting, and adjacent what is obtained
Multiple contraposition marks 120 are formed at the line of demarcation of the submounts 110, the contraposition mark 120 is the vacancy section of rectangle,
The multiple contraposition mark 120 is come on the line of demarcation by every predetermined quantity in the way of one group.
Such as Fig. 5, hyaline layer 140 is formed.The hyaline layer 140 is each right in the multiple hyaline layer 140 to be multiple
Contraposition mark 120 described in one group should be covered.The hyaline layer 140 is made of clear material, the step of forming hyaline layer 140
E.g.：Correspond to the position wire mark colourless solution of the contraposition mark 120, the colourless solution example on the glass substrate
Colourless phenolphthalein in this way.The material of the hyaline layer 140 is not limited to above-mentioned material, but in view of the preparation of the follow-up board unit
Process, preferably can be with obtaining the transparent material of non-transparent material after other substance reactions.
Such as Fig. 6, adjacent submounts 110 are separated.The step can be cut using cutting machine along the line of demarcation, cut
When cutting, the ccd image sensor that the cutting machine includes needs to carry out by the contraposition mark 120 on the glass substrate
Contraposition, the hyaline layer 140 being covered on the contraposition mark 120 is made up of transparent material, thus does not influence the ccd image to pass
The contraposition process of sensor.After cutting, the glass substrate as motherboard is divided into multiple submounts 110, the contraposition note
Numbers 120 are located at the edge of the submounts 110, and its shape remains as rectangle.
Such as Fig. 7, covering layer 130 is formed.Reacted using reactant with the hyaline layer 140, form non-transparent material
Covering layer 130, the covering layer 130 cover it is described contraposition mark 120, so as to prevent light leak.Form the covering layer 130
Step is, for example,：The submounts 110 that above-mentioned cutting is completed to obtain are cleaned using the solution for including the first reactant so that
The hyaline layer 140 is changed into nontransparent covering layer 130.Wherein, it is phenolphthalein corresponding to the colourless solution, the present embodiment is adopted
First reactant is that hydrogen ionexponent (Hydrogen ion concentration, PH) is 8.2-10.0
Alkaline solution, after cleaning, former colourless interior ester type structure phenolphthalein is changed into red quinoid knot after meeting first reactant
Structure phenolphthalein, and then form the red covering layer 130.
In the above-described embodiments, the colourless solution used in the step of formation covering layer 130 is colourless phenolphthalein, correspondence
The material of the covering layer 130 that the step of ground, formation covering layer 130 is formed is red quinoid structure phenolphthalein.It can manage
Different colourless solutions and the combination of corresponding first reactant can be used in solution, above-mentioned steps, is finally given
The material of the covering layer 130 can be corresponding different.In alternate embodiments：In the formation step of covering layer 130,
Colourless phenolphthalein is replaced using colourless lead nitrate solution (or silver nitrate solution)；Correspondingly, in the formation step of covering layer 130
In, use ammonium sulfide solution replace PH for 8.2-10.0 alkaline solution, then in cleaning process, the colourless solution with it is described
Chemical reaction shown in following ion equation can occur for the first reactant：
Pb2++S2-=PbS ↓
(or 2Ag++S2-=Ag2S↓)
That is vulcanized lead (or silver sulfide) precipitation of generation black, namely the vulcanization that the obtained covering layer 130 is black
Lead (or silver sulfide).So that the submounts 110 are assembled into after LCM, the backlight that passed through originally at the contraposition mark 120
Blocked by the covering layer 130, it is to avoid the side light leakage in the effective display area domain of the LCM (Active Area, AA) area,
Improve the quality of the LCM.
According to glass substrate of the present utility model, the covering layer 130 is pellucidity when the glass substrate is cut,
It is changed into non-transparent state after glass substrate cutting.So that easily being aligned during the glass substrate cutting, and cut
After can prevent light leak.
The utility model also provides a kind of liquid crystal display device, including：First substrate, second substrate and positioned at described
Liquid crystal molecule between one substrate and the second substrate.Wherein described second substrate includes the board unit in above-described embodiment
And electrode, the liquid crystal molecule rotates under the electric field action that electrode is produced.The covering layer 130 can stop backlight, make
The generation of light leakage phenomena can be prevented by obtaining the liquid crystal display device.
