Embodiment
Fig. 1 looks synoptic diagram on the display panel according to an embodiment of the invention.Fig. 2 is the diagrammatic cross-section along the profile line I-I ' of Fig. 1.Please refer to Fig. 1 and Fig. 2, the display panel of present embodiment has viewing area A, surrounding zone B and the frame glue district C between viewing area A and surrounding zone B.At this, surrounding zone B is looped around around the A of viewing area, and frame glue district C is between viewing area A and surrounding zone B.
In addition, display panel comprises first substrate 100, pel array layer 102, at least one connection pad electrode B P, second substrate 200, fluid sealant 400, at least one curtain wall structure W and display medium 300.
In addition, on second substrate 200, electrode film 202 can be set further.The electric field that produces between electrode film 202 and the pel array layer 102 can be controlled display medium 300 so that display panel demonstrates specific image.Above-mentioned electrode film 202 comprises transparent conductive material.It for example is indium tin oxide, indium-zinc oxide, aluminium tin-oxide, aluminium zinc oxide, indium germanium zinc oxide or other suitable oxide or the above-mentioned stack of layers of the two at least.In addition, second substrate 200 also can be provided with colour filter array (not illustrating) or other elements and rete in addition.
Among the frame glue district C of fluid sealant 400 between first substrate 100 and second substrate 200, so that first substrate 100 and second substrate stand/follow together for 200 groups, and fluid sealant 400 defines spatial accommodation between first substrate 100 and second substrate 200, and fluid sealant 400 can be the thermosetting cement material, irradiation solidifies glue material or other suitable materials.
In addition, be provided with connection pad electrode B P at first substrate 100, as shown in Figure 1.Because connection pad electrode B P at least partly is arranged among the frame glue district C, so connection pad electrode B P at least partly can cover by sealed glue 400.What deserves to be mentioned is that though present embodiment is that to show two connection pad electrode B P be that example illustrates, the present invention does not limit the number of connection pad electrode B P.In addition, present embodiment does not limit the position of connection pad electrode B P yet, all can so long as at least partly be arranged in arbitrary position of frame glue district C.
Fig. 3 is the enlarged diagram of the region R of Fig. 1, and Fig. 4 is the diagrammatic cross-section along the profile line II-II ' of Fig. 3.Please be simultaneously with reference to Fig. 1, Fig. 3 and Fig. 4, the connection pad electrode B P of present embodiment comprises electrode layer 110, overlayer 112 and contact electrode layer 114.Electrode layer 110 is to be positioned on first substrate 100, and the pel array layer 102 among itself and the viewing area A electrically connects.For instance, the electrode layer 110 of connection pad electrode B P and the common electrode line (not illustrating) in the pel array layer 102 electrically connect.Based on considering of electric conductivity and processing procedure convenience, electrode layer 110 is to adopt metal material, but the invention is not restricted to this.According to other embodiment, electrode layer 110 also can use other conductive materials.For example: the oxides of nitrogen of the nitride of alloy, metal material, the oxide of metal material, metal material or other suitable material, or the stack of layers of various suitable materials.
What deserves to be mentioned is, because the contact electrode layer 114 of connection pad electrode B P has the second channel patterns 114a, therefore when fluid sealant 400 is coated on frame glue district C, fluid sealant 400 might fill up the second channel patterns 114a of connection pad electrode B P fully, and makes to have at least one passage T between fluid sealant 400 and the connection pad electrode B P.At this, because the above-mentioned first channel patterns 112a and the second channel patterns 114a are net-like pattern or strip pattern, thereby the passage T between fluid sealant 400 and the connection pad electrode B P is netted passage (as shown in Figure 3) or strip passage (not illustrating), but the present invention this does not exceed.
