Embodiment
As shown in Figure 2, the display panels 2 of the preferred embodiment of the present invention has colored filter substrate 21, array base palte 23 and is folded between the two liquid crystal layer 27.Colored filter substrate 21 is a layer structure, is for 20 times transparency conducting layer 21a, colored filter 21b and transparency carrier 21c in regular turn in arranging lug.Array base palte 23 is a layer structure, is transparency conducting layer 23a, protective seam 23b, dielectric layer 23c and the transparency carrier 23d with slit 25 of corresponding arranging lug 20 in regular turn.When dark attitude, near the liquid crystal molecule 27a the arranging lug 20 is different with other regional liquid crystal molecule 27b, can't vertical substrate.Transparency conducting layer 21a and 23a can be identical or different material, as indium tin oxide (ITO), aluminium zinc oxide (AZO), indium-zinc oxide (IZO) or gallium zinc oxide (GZO).Protective seam 23b is generally monox, silicon nitride or silicon oxynitride.Dielectric layer 23c is preferably monox, silicon nitride or silicon oxynitride.Transparency carrier 21c and 23d can be identical or different transparent material, as glass, plastics, quartz or other pliability material.
The difference of liquid crystal panel 2 and liquid crystal panel 1 is the optical density (OD) of arranging lug 20, and (opticaldensity is OD) between 0.3/ μ m to 3/ μ m, preferably between 0.8/ μ m to 1.3/ μ m.Optical density (OD) is defined as log (1/T), and T is penetrance (0 to 100%).If arranging lug is a penetrance when being 100% transparent material, optical density (OD) is 0.When arranging lug is a penetrance when leveling off to 0 black material, optical density (OD) then levels off to infinity.Because thick more arranging lug, its optical density (OD) is big more, is clear definition, and optical density (OD) of the present invention is a unit with μ m.Because the optical density (OD) of arranging lug 20 in above-mentioned scope, therefore can reduce the dark attitude light leak that transparent arranging lug 10 causes.
The light leak curve 29 of Fig. 2 obviously improves many than the light leak curve 19 of Fig. 1.Will be appreciated that the optical density (OD) of arranging lug 20 is high more, then the light leak curve is mild more, up to forming horizontal line.But be limited to 3 on the optical density (OD) of arranging lug 20 of the present invention, because too high optical density (OD) will make the alignment mark (not shown) on colored filter substrate and the array base palte aim at.Be understandable that, cover, then during the stage, possibly can't detect the alignment mark on the colored filter substrate in exposure technology if the alignment mark on the colored filter substrate is arranged projection.Even adopt alignment mark to avoid the design of arranging lug, the black arranging lug also can cause aperture opening ratio to descend.The problem that the optical density (OD) that the arranging lug 20 of present embodiment adopts then can avoid above-mentioned black arranging lug to cause, and need not redesign the arrangement plan of alignment mark and arranging lug, escapable cost.
The material of above-mentioned arranging lug 20 can be organic material, inorganic material or both composite material mixed.The optical density (OD) of arranging lug 20 is to regulate and control with metal oxide, carbon black, dyestuff, pigment or combinations thereof, and above-mentioned substance is high more in the concentration of arranging lug 20, and then optical density (OD) is big more.So its addition will be looked its required optical density (OD) and do suitably to adjust.Will be appreciated that, can select for use metal oxide, carbon black, dyestuff or the pigment of different colours to make arranging lug 20 have different colors, as redness, blueness, green, cyan, aubergine, grey, brown or yellow.In the present embodiment, the common electrode 24 of array base palte 23 can be overlapped to improve aperture opening ratio at least with arranging lug 20.
Though the section of the arranging lug 20 in Fig. 2 is a triangle, the arranging lug that one of ordinary skill in the art should understand herein can adopt other section shape as circle, ellipse, triangle, trapezoidal, square or rectangle.For simplified manufacturing technique and saving mask cost, the arranging lug in the same liquid crystal panel preferably has identical section shape.
Though in Fig. 2, arranging lug 20 is positioned on the colored filter substrate 21, and the substrate that is oppositely arranged is array base palte 23, and arranging lug 20 of the present invention is not limited to be formed on the colored filter substrate.For instance, arranging lug 20 can be formed on the array base palte 23, and its corresponding slit 25 is formed on the colored filter substrate 21.In other preferred embodiment of the present invention, as the liquid crystal panel 3 of Fig. 3, even can adopt another arranging lug 30 to replace the effect of slits, and the optical density (OD) of another arranging lug 30 preferably the optical density (OD) with arranging lug 20 is identical.In other preferred embodiment of the present invention, liquid crystal panel can adopt colored filter at (COA) or array base palte on the array base palte on colored filter (AOC), and arranging lug can be arranged on COA or the AOC, or is arranged on its relative substrate.No matter which kind of substrate liquid crystal panel adopts,, can effectively solve known transparent or problem that the black arranging lug is caused as long as adopt the arranging lug that has the optical density (OD) of particular range among the present invention.Arranging lug 20 and 30 material, shape, size or optical density (OD) can be similar and different.
Though the present invention with a plurality of preferred embodiments openly as above; right its is not in order to restriction the present invention; any one of ordinary skill in the art; without departing from the spirit and scope of the present invention; when can changing arbitrarily and modify, so protection scope of the present invention is as the criterion when looking the scope that accompanying Claim defines.
