The structure of second accommodation space 314 is similar to above-mentioned first accommodation space 304, difference is, first accommodation space 304 is arranged on the corner portion 302a～302d of border structure 300, and second accommodation space 314 be arranged on border structure 300 edge strip structure 300a～300d at least one of them.In addition, fence gate structure (fence gate structure 500 as shown in Figure 1) or the fence gate structure is not set also can be set between second accommodation space 314 and cavity CH.Similarly, second catch gas material 410 and comprise that eruption type is caught the gas material, non-eruption type is caught gas material or both combinations.If second to catch gas material 410 be to adopt eruption type to catch the gas material, between second accommodation space 314 and cavity CH, preferably be provided with fence gate structure (fence gate structure 500 as shown in Figure 1) so.
In the present embodiment, preferably, be positioned at border structure 300 corner portion 302a～302d first to catch the gas material be to adopt eruption type to catch the gas material, and the edge strip structure 300a～300d that is positioned at border structure 300 at least one of them second to catch gas material 410 be to adopt non-eruption type to catch the gas material.And eruption type is caught corner portion 302a～302d that the gas material is arranged on border structure 300, and it is as follows that non-eruption type is caught one of them the Consideration at least of edge strip structure 300a～300d that the gas material is arranged on border structure 300.
In general it is preferable that eruption type is caught the inspiratory effects of gas material, mainly be because eruption type to catch the activation temperature of gas material higher, therefore act on when the temperature of display floater in encapsulating the technology of bleeding just may allow non-eruption type catch the gas material in advance, thereby expend the gettering ability of part.Eruption type catch the gas material then after display floater encapsulation is finished again with high-temperature activation, therefore can keep its gettering ability and after the display floater encapsulation, just act on.In addition, eruption type is caught the gas material because the effect of eruption can enlarge the area that it contacts with residual gas, so gettering efficiency is preferable.Moreover, eruption type is caught gas material and non-eruption type, and to catch both absorbable gaseous species of gas material roughly the same, but for the absorption of hydrogen, it is irreversible reaction that eruption type is caught the gas material, but not eruption type to catch the gas material be reversible reaction (normal temperature absorbs, and the back hydrogen of heating takes off to be paid).And usually display floater is easier to corner residual gas at display floater in carrying out exhaust air technique after, and the eruption type that therefore will have strong inspiratory effects is caught the front of help corner portion 302a～302d that the gas material is arranged on border structure 300 has to(for) the gettering efficiency of display floater.
In addition, eruption type is caught the gas material and is formed metal film because can react ejection, has near the of lead winding displacement in order to avoid cause short circuit so be unsuitable for being placed on.In other words, the edge strip structure 300a～300d part at border structure 300 is fit to adopt non-eruption type to catch the gas material.In addition, after completing, display floater when normally showing operation, may produce the gas of small part.Therefore, non-eruption type is caught edge strip structure 300a～300d that the gas material is arranged on border structure 300 one of them can carry out getter action to the gas that comes from active region A at least.Because set second catches gas material 410 and makes and adopt non-eruption type to catch the gas material in second accommodation space 314 of the edge strip structure 300a～300d of border structure 300, so the setting that can omit the fence gate structure between second accommodation space 314 and the cavity CH.
Figure 10 looks schematic diagram on the display floater according to another embodiment of the present invention.The embodiment of Figure 10 is similar to the embodiment of Fig. 9, so components identical is with identical symbolic representation, and no longer repeat specification.In the embodiment of Figure 10, between second accommodation space 314 and cavity CH, be provided with fence gate structure 510, and fence gate structure 510 is integrally formed structures with border structure 300.In other words, in the embodiment of Figure 10, second accommodation space 314 is arranged on the inside of border structure 300, and sees through the design of similar L shaped passage between second accommodation space 314 and the cavity CH, makes that the part of border structure 300 can be directly as fence gate structure 510.In this embodiment, because of being provided with fence gate structure 510 between second accommodation space 314 and the cavity CH, therefore being arranged on second in second accommodation space 314 and catching gas material 410 and can make and adopt eruption type to catch the gas material, but the invention is not restricted to this.
