Embodiment
For making those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Embodiment 1
As shown in Figure 2-5, the present embodiment provides a kind of liquid crystal display substrate, comprise: for the viewing area 1 that shows and the neighboring area 2 being positioned at described viewing area 1 periphery, described neighboring area 2 also comprises and is positioned near the buffer area 21 of viewing area 1 periphery and the sealing region 22 away from described viewing area 1; Described buffer area 21 is provided with for stopping that liquid crystal alignment liquid diffuses to the stop dam of sealing region 22.
Owing to being provided with for stopping that liquid crystal alignment liquid diffuses to the stop dam of sealing region 22 in the buffer area 21 of substrate, the diffusion of liquid crystal alignment liquid is made to obtain effective control, can ensure that liquid crystal alignment liquid diffuses to buffer area 21 certain distance, unlikelyly again diffuse to sealing region 22, thus affect the solidification of sealed plastic box in this region.
Particularly, liquid crystal display substrate can be thin-film transistor array base-plate or color membrane substrates, is introduced below for thin-film transistor array base-plate, if the corresponding region of color membrane substrates only need arrange by color membrane substrates stop dam.
As shown in Figures 2 and 3, stop that dam comprises multiple roundabout unit 3 being located in described viewing area 1 periphery, the working direction (in Fig. 3 direction shown in arrow) of described roundabout unit and the boundary line of described viewing area 1 are non-parallel setting.In other words, be exactly angled setting.
Preferably, roundabout unit 3 is the coiling of bow font, the coiling of described bow font comprises multiple blend stop 31, make liquid crystal alignment liquid on the direction diffusing to sealing region 22, need multiple blend stops 31 of cross-domain bow font coiling like this, thus make liquid crystal alignment liquid partial liquid crystal alignment liquid when cross-domain blend stop 31 be trapped in region between each blend stop 31, thus the diffusion length of liquid crystal alignment liquid can be controlled piecemeal.
Preferably, the working direction of described bow font coiling and the boundary line of described viewing area 1 are vertical setting.Need the number of the blend stop 31 of cross-domain bow font coiling maximum like this in unit diffusion length, also with regard to the diffusion length of the more effective control liquid crystal alignment liquid of energy.
Preferably, described each bow mutually between font coiling has gap area, and this gap area can make the appropriate adjustments according to the viscosity size of liquid crystal alignment liquid, can ensure that liquid crystal alignment liquid has certain diffusion, is unlikely to again long along this gap area diffusion length.
As shown in Figure 3, preferably, the distance D1 that the coiling of described bow font is once advanced is 1-20um; Described bow font coiling length D2 is in a forward direction 3-100um.Should be understood that, above-mentioned D1 and D2 can carry out regulating according to the sight of application, if desired weakens barrier effect and then D1 can be increased, namely reduce the density of blend stop 31, shorten the length of D2 simultaneously, reduce the number of blend stop 31.If otherwise strengthen barrier effect, D1 can be reduced, namely increase the density of blend stop 31, increase the length of D2 simultaneously, increase the number of blend stop 31.
As shown in Figure 4, preferably, between the coiling of described each adjacent bow font, there is intersection region.Wherein, described intersection region refers to the state in region very close to each other between adjacent bow font coiling, and when the viscosity of liquid crystal alignment liquid is too small, the bow font coiling of the type arranges and can control liquid crystal alignment liquid diffusion length preferably.
Preferably, the coiling of described bow font is being 2000-8000 dust perpendicular to the height on orientation substrate.Highly can adjust by adjustment the volume being detained liquid crystal alignment liquid between adjacent two blend stops 31, thus control the intensity of stop.
Should be understood that, zigzag coiling as shown in Figure 5, and the roundabout coiling of other type is all applicable.Again do not do too much restriction.
The conductive layer of described roundabout unit and described thin-film transistor array base-plate is arranged with layer.That is in patterning processes, in thin-film transistor array base-plate, metal level is prepared simultaneously.Patterning processes is that this is no longer going to repeat them for prior art category.
Wherein, conductive layer can be grid layer or source, drain electrode layer.Be to be understood that, other metal level is also applicable.
