More specifically, comprise on first substrate 102 be provided with pel array 150, the lead-in wire L, organic layer 122 and conductive pattern 124.
Particularly, in the present embodiment, in the beneath shielding pattern layer 124 that more includes of organic layer 122, shielding pattern layer 124 is arranged in viewing area 110 and non-display area 120.Shielding pattern layer 124 in viewing area 110 is a reticulate texture, the promptly corresponding dot structure (or be called pixel region or be called effective viewing area) in each space in this reticulate texture, so shielding pattern layer 124 can be described as black matrix" again.Shielding pattern layer 124 in non-display area 120 is ring texture or shaped as frame structure, its be centered around viewing area 110 around.Particularly, the shielding pattern layer 124 that is arranged in non-display area 120 covers the top of lead-in wire L, and is more covered the preferably blue filter pattern of this organic layer 122b by organic layer 122b on the shielding pattern layer 124 of lead-in wire L top.In the present embodiment, the material of shielding pattern layer 124 comprises black resin.
In addition, in a preferred embodiment, on organic layer 122, more comprise being coated with another layer protective seam 116.Protective seam 116 can be the single or multiple lift structure, and its material (for example: silicon nitride can be inorganic insulating material; monox; silicon oxynitride; persilicic nitride; silicon rich oxide; the Silicon-rich oxides of nitrogen; rich nitrogen silicide; the oxygen enrichment silicide; rich nitrogen-oxygen-silicon thing; or other suitable material; or above-mentioned combination arbitrarily); organic insulation (for example: polyester film (PET film); the polyalkenes film; poly-propionyl class film; polycarbonate-based film; polyalkylene oxide class film; polyphenyl alkene class film; the polyethers film; polyketone class film; the polyalcohols film; polyacetals class film; or other suitable material; or above-mentioned combination); or other suitable material; or above-mentioned combination arbitrarily.At this moment, another layer protective seam 116 can be described as flatness layer (flatnesslayer) or overlayer (overcoat layer), and its material also can use material described above.But, in other embodiment, can omit protective seam 116.
In addition, on the protective seam 116 of non-display area 120, then be provided with conductive pattern 156 in addition, and this conductive pattern 156 is to be positioned on the organic layer 122 of lead-in wire L top.In the present embodiment, preferably, conductive pattern 156 is to form simultaneously with pixel electrode 152, therefore the material of conductive pattern 156 is identical with the material of pixel electrode 12, and it for example is transparent metal oxide (as: indium tin oxide, indium-zinc oxide, indium germanium zinc oxide, aluminium zinc oxide, indium germanium oxide, indium aluminum oxide or other suitable material or above-mentioned combination arbitrarily).In other embodiment, also be not limited thereto.In the present embodiment, conductive pattern 156 is to separate mutually with pixel electrode 152, preferably, conductive pattern 156 be with pixel electrode 152 be to be electrically insulated mutually.In the present embodiment, the shape of conductive pattern 156 is that example illustrates with the rectangle, but the invention is not restricted to this, and it also can be other shape, for example is finger-like structure, polygonized structure or the like, so long as can get final product above lead-in wire L.
In addition, more can comprise in the viewing area 110 on first substrate 102 being provided with both alignment layers 158, use so that display medium 106 can have specific tilt angle.In the present embodiment, preferably, both alignment layers 158 only is arranged in the viewing area 110, and promptly both alignment layers 158 is arranged on the pixel electrode.
In addition, second substrate 104 is positioned at the subtend of first substrate 102, and comprises on second substrate 104 and be provided with transparent electrode layer 162, and transparent electrode layer 162 is arranged in viewing area 110 and non-display area 120.In other words, transparent electrode layer 162 extends in the non-display area 120 from viewing area 110.In addition, more can comprise in the viewing area 110 on second substrate 104 being provided with both alignment layers 164, use so that display medium 106 can have specific tilt angle.In the present embodiment, preferably, both alignment layers 158 set positions correspond to the position of both alignment layers 164.In other words, the edge of both alignment layers 158 is the edges that trim both alignment layers 164.Particularly, the conductive pattern 156 on the transparent electrode layer 162 and first substrate 102 is electrically connected to a common voltage.Wherein, transparent electrode layer 162 materials can be selected the material of pixel electrode 12 for use, but the material of said two devices can be identical or different.In addition, must it should be noted that the material of transparent electrode layer 162 can't be used light tight material (as: gold, silver, copper, aluminium, titanium, tantalum, alloy or other suitable material or above-mentioned combination arbitrarily) instead.Because the observer is the light that back light BL was observed and found to the outside surface that is positioned at second substrate 104.That is to say that the observer is positioned at outside the surface that second substrate 104 do not exist alignment film 164 and transparent electrode layer 162.If the material of transparent electrode layer 162 can't be used light tight material instead and just can't be reached the effect that allows the observer observe.
Because transparent electrode layer 162 is electrically connected to a common voltage with conductive pattern 156, therefore voltage difference is does not die the display medium (liquid crystal molecule) between transparent electrode layer 162 and the conductive pattern 156 106 because have, so the liquid crystal molecule 106 of this part can not produce any behavior of reversing.In other words, because the bridging effect of conductive pattern 156, the liquid crystal molecule 106 that the voltage of lead-in wire L can't influence its top produces the behavior of reversing, thereby the liquid crystal molecule 106 above lead-in wire L will continue to keep the state of homeotropic alignment.So, because event of the homeotropic alignment of the liquid crystal molecule 106 of lead-in wire L top just can not penetrated second substrate 104, and then can avoid the situation of this place's generation light leak from the back light BL that the back side provided of first substrate 102.
