Referring to Fig. 2, be the structural representation of display panels among the embodiment of the utility model, the viewing area of zone, the right for marking off of arrow indication among the figure, the left area of arrow indication is the outer peripheral areas that marks off.
In the present embodiment; This display panels comprises: first substrate 11 that is oppositely arranged and second substrate 12, be arranged on the light shield layer 13 on said first substrate 11, and envelope frame glue 14; Wherein, be formed with the fluting 15 that extends to described first substrate 11 on institute's light shield layer 13;
One end of said envelope frame glue 14 penetrates fluting 15 and directly contacts with said first substrate 11, and the other end of said envelope frame glue 14 contacts with said second substrate 12.
As shown in Figure 2, this first substrate 11 comprises first electrode layer 111, and an end of said envelope frame glue 14 directly contacts with first electrode layer 111 on first substrate 11.
In the present embodiment; Through sealing first electrode layer, 111 contact areas of frame glue 14 and first substrate, 11 sides; Can guarantee to seal the adhesion of frame glue 14 and first substrate, 11 sides; Avoided contacting with light shield layer 13 because of envelope frame glue 14 in the prior art; The adhesion of influence envelope frame glue 14 and first substrate 11 causes first substrate 11 (for example CF substrate) of display panels to separate, come off with second substrate 12 (for example array base palte) and bad generation such as liquid crystal leakage, can improve the quality of liquid crystal display product through the structure in the employing present embodiment.
In the present embodiment, because the friction force and the supporting role of the sidewall of fluting 15 can increase the adhesion of sealing frame glue 14 and first substrate, 11 sides.
Further, sealing not light leak of frame glue 14 dispensing areas in order to guarantee second substrate, 12 sides, this second substrate 12 comprises: be used to prevent the barrier bed 16 of light leak, this envelope frame glue 14 contacts with barrier bed 16.
In the present embodiment, second substrate 12 also comprises the second electrode lay 121, and this barrier bed 16 is located on the second electrode lay 121.
As shown in Figure 2, barrier bed 16 is arranged on the second electrode lay 121, contacts corresponding to envelope frame glue 14 region covered and with envelope frame glue 14, and what certainly can understand is that those skilled in the art can adjust the width of barrier bed 16 as the case may be.
In the present embodiment, this first substrate 11 is the CF substrate, and this second substrate 12 is an array base palte.In other embodiments, also can be with array base palte as first substrate 11, with the CF substrate as second substrate 12.
In the present embodiment, the material of this first electrode layer 111 and the second electrode lay 121 can be selected indium tin oxide for use, and what certainly can understand is not limit the concrete material of this first electrode layer 111 and the second electrode lay 121 in the present embodiment.
In the present embodiment, this light shield layer 13 can select for use black matrix layer to realize the function of its shading, and for example the black matrix layer of light shield layer 13 and viewing area is by forming with layer of material.What certainly can understand is not limit the concrete material of this light shield layer 13 in the present embodiment.
In the present embodiment, this barrier bed 16 can select for use the metallic signal lines layer to realize the function that it blocks, and the width of this barrier bed 16 is than the big 0.1mm～0.3mm of width of envelope frame glue 14 corresponding ends, for example 0.2mm.As shown in Figure 2, two limits of this barrier bed 16 are than each wide 0.2mm of two limits of envelope frame glue 14.
In the present embodiment, barrier bed 16 can with the metallic signal lines layer of viewing area by forming with layer of material, said metallic signal lines layer is sweep trace layer (being grid line layer) or data line layer.
Below in conjunction with Fig. 2, the principle of introducing these barrier bed 16 coverings in the present embodiment is:
1. in manufacture process, the barrier bed 16 on the second electrode lay 121 can adopt with the data line layer with the viewing area and process with layer of material.Consider envelope frame glue 14 coating precision, barrier bed 16 can wide 0.1mm～0.3mm (for example 0.2mm) than the corresponding end of envelope frame glue 14, and is as shown in Figure 2;
Certainly, barrier bed 16 breaks off not conducting with other data line layer.
2. in manufacture process, the barrier bed 16 on the second electrode lay 121 also can adopt with the sweep trace layer (grid line layer) with the viewing area and process with layer of material.。Consider envelope frame glue 14 coating precision, barrier bed 16 can wide 0.1～0.3mm (for example 0.2mm) than envelope frame glue 14 corresponding ends;
Continuation is referring to Fig. 2; It is the periphery design schematic cross-section of display panels in the present embodiment; When the size design space of outer peripheral areas is less; The zone that envelope frame glue 14 contacts with first substrate 11 does not have light shield layer 13, and envelope frame glue 14 directly contacts with first electrode layer 111 of first substrate, 11 sides.First substrate, 11 side peripheries are except the dispensing area of envelope frame glue 14, and other zones part are at least covered by light shield layer 13, guarantee that like this envelope frame glue 14 of first substrate, 11 sides does not overlap with light shield layer 13;
On the other hand; Because corresponding envelope frame glue 14 dispensing areas of first substrate, 11 sides have not had light shield layer 13; It is bad that display panels may light leak take place in these positions; These corresponding envelope frame glue 14 dispensing areas of second substrate, 12 sides this moment can select for use barrier bed 16 to cover (for example barrier bed 16 directly contacts with the second electrode lay), and assurance should light leakage phenomena can not take place in the zone.
Can know that by technique scheme the embodiment of the utility model has following beneficial effect:
At first; The contact area of the envelope frame glue and first substrate-side all is set to first electrode layer; Can guarantee to seal the adhesion of the frame glue and first substrate-side, avoid envelope frame glue contact, effectively prevent to separate, come off with second substrate (for example array base palte) and bad generation such as liquid crystal leakage owing to sealing make a concerted effort first substrate (for example CF substrate) of the bad display panels that causes of frame gluing with the overlapping of light shield layer; Improve product quality, guaranteed to produce the production of line.
Secondly, in the array base palte side, also be provided with barrier bed between envelope frame glue and the second electrode lay, assurance array base palte side is being sealed not light leak of frame glue dispensing area.
At last, the friction force between the sidewall of the fluting through envelope frame glue and light shield layer can further strengthen sealing the adhesion of the frame glue and first substrate-side.
The liquid crystal indicator that the utility model embodiment is provided comprises a kind of above-mentioned display panels.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
