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 4, the present embodiment provides a kind of display panel, it comprises mutually to first substrate 1 and the second substrate 2 of box, liquid crystal molecule 3 is filled with at first substrate 1 and second substrate 2, sealed by sealed plastic box 5 in the neighboring area of first substrate 1 and second substrate 2, in the one side of described second substrate 2, be disposed with chock insulator matter 4, first alignment films 11 at described first substrate 1; In the one side of first substrate 1, be provided with the second alignment films 21 at described second substrate 2, described first alignment films 11 is at least provided with the first opening 111 with the position corresponding to described chock insulator matter 4; And/or at least corresponding with described chock insulator matter 4 position is provided with the second opening 211 in described second alignment films 21.
That is, at least one in the first alignment films 11 in an embodiment and the second alignment films 21, the position corresponding with chock insulator matter 3 is provided with " opening " (first opening 111 or second opening 211).And just because of the setting of " opening ", avoid the first orientation 11 film and the position of the second alignment films 21 corresponding to chock insulator matter 3 contacts, thus prevent when carrying out sanding and polishing to display panel, the first alignment films 11 is caused to produce friction with the second alignment films 21 because both contact, easy generation chip, and the chip produced inevitably enters the viewing area of display panel, and then display panel is caused to produce the bad phenomenon such as broken bright spot.
Wherein, first substrate 1 is color membrane substrates, and second substrate 2 is array base palte; Or first substrate 1 is array base palte, second substrate 2 is color membrane substrates.Certainly, first substrate 1 can also be to box substrate, and second substrate 2 is array base palte; Or first substrate 1 is array base palte, second substrate 2 is to box substrate.Following first substrate 1 is color membrane substrates, and second substrate 2 is described the present embodiment for array base palte.
As a kind of optimal way of the present embodiment, the first alignment films 11 on color membrane substrates 1 is at least provided with the first opening 111, the second alignment films 21 on array base palte is at least provided with the second opening 211.
That is, the first alignment films 11 and the second alignment films 21 there will not be the position contacted, thus avoid because both the first alignment films 11 and the second alignment films 21 produce friction and occur chip, cause display panel to show bad phenomenon.
Preferably, the display panel of the present embodiment, comprise the viewing area 6 of setting in column of embarking on journey, and be arranged on the non-display area between any two adjacent display areas 6, the position of the first opening 111 in described first alignment films 11 is corresponding with the position of at least part of described non-display area.Now, the arrangement of liquid crystal molecule can not be affected, also can not affect the display effect of display panel simultaneously.
Wherein, described chock insulator matter 4 is arranged on the non-display area of described display panel, and the position of the first opening 111 of described first alignment films 11 is corresponding with the position of the non-display area that described chock insulator matter 4 is expert at.Why so arrange and be, because the non-display area on color membrane substrates 1 is provided with black matrix usually, and chock insulator matter 4 is also just arranged on black matrix position place, the now then black matrix position of corresponding a line, the position of the first opening 111, also namely in chock insulator matter 4 first alignment films 11 that is not provided with in the row direction, as shown in Figure 5.
Wherein, the first opening 111 marginal position to the minimum distance of chock insulator matter 4 between 1 μm ~ 50 μm.This span specifically can set according to the size of display panel.Because the edge of the first opening 111 and chock insulator matter 4 there is certain distance, therefore can prevent when color membrane substrates 1 and array base palte 2 pairs of boxes, owing to there is inevitable error, and cause the first alignment films 11 and the second alignment films 21 to contact and produce friction and occur chip, cause display panel to show bad phenomenon.
Wherein, the position of the second opening 211 in the second alignment films 21 is corresponding with the position of the first opening 111 in the first alignment films 11.Thus avoid the first alignment films 11 and the second alignment films 21 contacting with the position corresponding to chock insulator matter 4 completely.
As shown in Figures 6 and 7, as the another kind of optimal way of the present embodiment, the first opening 111 in the first alignment films 11 is all corresponding with chock insulator matter 4 position with the second opening 211 in the second alignment films 21.
Wherein, described first opening 111 is identical with the shape of described second opening 211, can be all any one in circle, rectangle, rhombus.The shape of the first opening 111 and the second opening 211 can certainly be set according to the shape of chock insulator matter 4.
Wherein, described first opening 111 and the second opening 211 edge are 1 μm ~ 50 μm to the scope of the minimum distance of described chock insulator matter 4.This span specifically can set according to the size of display panel.Because the edge of the first opening 111 and chock insulator matter 4 there is certain distance, therefore can prevent when color membrane substrates 1 and array base palte 2 pairs of boxes, owing to there is inevitable error, and cause the first alignment films 11 and the second alignment films 21 to contact and produce friction and occur chip, cause display panel to show bad phenomenon.
Above-described embodiment is all for color membrane substrates with first substrate 1, second substrate 2 for array base palte be that example is described, even if in like manner first substrate 1 is array base palte, second substrate 2 is that color membrane substrates also can arrange the first alignment films 11 and the second alignment films 21 according to above-mentioned embodiment.
Embodiment 2:
The present embodiment provides a kind of preparation method of display panel, and wherein, display panel can be the display panel shown in embodiment 1.Described preparation method comprises: form the first alignment films 11 on first substrate 1, and forms the step of the second alignment films 21 on second substrate 2.
Concrete, this preparation method comprises: by letterpress or ink-jetting process, forms the first oriented film on first substrate 1, forms the second oriented film on second substrate 2.
Wherein, form oriented film for ink-jetting process to be described.As shown in Figure 8, the jet board of ink of ink-jet apparatus has multiple little pin hole, little pin hole each little pin hole of closely arranging can spray the orientation liquid of fixed amount.Little pin hole 71 on jet board of ink 7 is not the arrangement of full plate, little pin hole 71 (namely the first opening 111 or the second opening 211) is not had at permanent opening 72, the position of the corresponding above-mentioned chock insulator matter 4 in this position 72, rounded shape, this position 1 ~ 20um larger than chock insulator matter 4.
By friction process, evaporation process or light orientation, respectively orientation is carried out to the first oriented film and the second oriented film, to form the first alignment films 11 and the second alignment films 21.
Be understandable that, the illustrative embodiments that above embodiment is only used to principle of the present invention is described and adopts, but the present invention is not limited thereto.For those skilled in the art, without departing from the spirit and substance in the present invention, can make various modification and improvement, these modification and improvement are also considered as protection scope of the present invention.
