Defeated pad PAD2 is electrically connected to each other.In addition, in the present embodiment, metal switching is further included in the Zhou Bianqu 112 of first substrate 110
Pad 120, metal switching pad 120 is electrically connected by the contact hole 132 in insulating barrier 130 with the first electrical PAD1 of transmission pad：Metal
Switching pad 120 can for example be electrically connected with the common line in pixel cell in the present embodiment, thereby, common electrode CE and second
Transmission pad PAD2 may be electrically connected to the first electrical PAD1 of transmission pad, metal switching pad 120 and common line, to provide certain electricity
Position.
Additionally, in the present embodiment, a conducting element 400 is configured between array base palte 100 and opposite substrate 200, and
And around display dielectric layer 300.The first electrical PAD1 of transmission pad passes through conductive frame glue 400 and is electrically connected with the second transmission pad PAD2.
In the present embodiment, conducting element 400 is, for example, by insulation glue material 410 and the conducting particles 420 being doped in insulation glue material 410
Constituted, conducting particles 420 is randomly dispersed in insulation glue material 410, wherein the material of insulation glue material 410 is, for example, tree
Fat, and conducting particles 420 is, for example, gold goal (Au balls).Because conducting particles 420 is to be doped in insulation glue material 420 in advance
In, therefore after the coating of conductive frame glue 420, the first electrical PAD1 of transmission pad is electrically connected with the second transmission pad PAD2.
In the present embodiment, the first alignment film 240 and the second alignment film 140 can be with an ink jet printing (inkjet) technique skills
Art is made.The preparation method of the second alignment film 140 is, for example, to be formed with the transmission of pixel cell PU and first pad electrically
An alignment materials solution is sprayed on the first substrate 110 of the elements such as PAD1, a curing process is then carried out, so that alignment materials are molten
Liquid is solidified into the second alignment film 140.Similarly, the preparation method of the first alignment film 240 be, for example, be formed with light shield layer 220 with
An alignment materials solution is sprayed on the second substrates 210 of element such as the second electrical PAD2 of transmission pad, a solidification work is then carried out
Skill, so that alignment materials solution is solidified into the first alignment film 240.Foregoing curing process is, for example, heat curing process, ultraviolet
Curing process or other appropriate curing process.What deserves to be explained is, the opposite substrate of the display panel in the present embodiment, its
The unit light shielding part 222 of light shield layer 220 has multiple slits 224, therefore using ink-jet printing process the second of opposite substrate
When an alignment materials solution is sprayed on substrate, the second transmission pad PAD2 of adjacent unit light shielding part 222 can be avoided by orientation material
Material solution is covered, and can simultaneously meet the full alignment materials of viewing area covering of opposite substrate.The present invention implements the of profit
One alignment film 240 is not limited to an ink jet printing (inkjet) technology and is made with the second alignment film 140, first orientation of the present embodiment
Film 240 can also coating technique make and be formed on common electrode CE and the second alignment film 140 can also coating technique system
It is formed on pixel cell PU.
In the present embodiment, the kenel of display panel 10 is not limited, wherein with the difference of display dielectric layer 300, showing
Show that panel 10 has different mechanism of action.For example, display dielectric layer 300 can be liquid crystal material or other equally have
The material of orientation demand.When display dielectric layer 300 is liquid crystal material, then display panel 100 is referred to as liquid crystal display panel.Citing
For, liquid crystal display panel can be vertical electric field type liquid crystal display panel, for example, vertical orientation (VA) type LCD
Plate, liquid crystal display panel can also be horizontal electric field type liquid crystal display panel, for example, plane switch type (IPS) LCD
Plate or fringe field switch type (FFS) liquid crystal display panel.Certainly, those skilled in the art will be understood that the design of the present embodiment
Concept still can be reasonably applied in other kinds of display panel.
Additionally, in the present embodiment, array base palte 100 is, for example, thin-film transistor array base-plate.In other embodiments,
Array base palte 100 can also further include chromatic filter layer (not illustrating) between flatness layer PL and pixel electrode PE, also
It is COA (the Color Filter on Array) substrate of integral color filter layer in array base palte 100.
From the above, in the display panel of the present embodiment, because the unit light shielding part of light shield layer has the design of slit,
An accommodation space for communicating with each other can be formed inside unit light shielding part, when alignment materials solution spraying is adjacent to the second transmission pad
During unit light shielding part, alignment materials solution just can circulate in the space inside unit light shielding part by slit, and equably
It is distributed in the space inside unit light shielding part, there is larger permission with the precision controlling for ink-jet printing process.By
This, can be avoided the first alignment film from covering the second transmission pad so that the first transmission pad and the of opposite substrate of array base palte
Two transmission pads can keep good electrical connection.
Furthermore, because the unit light shielding part of light shield layer has the design of slit, the viewing area in second substrate adjacent perimeter area
May insure that alignment film is completely covered so that the viewing area in second substrate adjacent perimeter area can provide effective orientation, it is to avoid aobvious
Show dielectric layer molecule (for example：Liquid crystal molecule) arrangement is abnormal causes the doubt of light leak, can lift display quality
Display panel 10 according to a first embodiment of the present invention, its second transmission pad PAD2 and unit light shielding part 222 are
It is configured at a border 212S1.However, the second transmission pad PAD2 can be different with design requirement, for example, such as scheme
Shown in 7, in an alternate embodiment, the second transmission pad PAD2 of opposite substrate 200A can be configured at border 212S1, border
The Zhou Bianqu 214 of 212S2, border 212S3 and border 212S4, and unit light shielding part 222 is relative to the second PAD2 pairs, transmission pad
The viewing area 212 of border 212S1, border 212S2, border 212S3 and border 212S4 should be disposed adjacent to.Opposite substrate
The four second transmission pad PAD2 of 200A are electrically connected with four first transmission pad PAD1 of array base palte 100.
Fig. 8 is the upper schematic diagram of the opposite substrate of the display panel of second embodiment of the invention.Fig. 9 A are cuing open along Fig. 8
