Figure 1B is the diagrammatic cross-section that I-I section along the line is drawn among Figure 1A.

Embodiment

Figure 1A is the overlooking surface synoptic diagram of the substrate of the display with no periodic array distance piece of the utility model one embodiment.See also Figure 1A, substrate 100 with display of no periodic array distance piece can be applied to LCD, and comprise a flat board 110 and an a plurality of distance piece 120, wherein these distance pieces 120 all are configured on dull and stereotyped 110, and for example being a plurality of smooth distance pieces, can be photoresistance (photoresist) so constitute the material of distance piece 120.

Dull and stereotyped 110 can be colored optical filtering substrates or active assembly array substrate, and have a plate face 112, and these distance pieces 120 are configured on the plate face 112 entirely, promptly distance piece 120 all the position on the same side of dull and stereotyped 110.Plate face 112 is divided into a middle section 112a and a neighboring area 112b, and wherein neighboring area 112b surrounds middle section 112a.120 of a little distance pieces in the 112b of neighboring area, other distance piece 120 then the position in middle section 112a.

These distance pieces 120 are to be configured on the plate face 112 in the no periodic array mode.Specifically, from whole plate face 112, any order (order) or cycle are not followed in all distance piece 120 distributions on plate face 112.That is to say, these distance pieces 120 can be with chaos (chaos) or at random (random) mode of arranging be configured on the plate face 112.In addition, all distance pieces 120 might not be to be evenly distributed on the plate face 112, and for example the distribution of the distance piece shown in Figure 1A 120 on plate face 112 is obviously also inhomogeneous.

The quantity that is positioned at these distance pieces 120 of middle section 112a can be M, and that the quantity that is positioned at these distance pieces 120 of neighboring area 112b can be N is individual, so M, N are all natural number.In addition, M and N can satisfy the condition of M ≧ N, and the quantity that just is positioned at the distance piece 120 of middle section 112a can be more than or equal to the quantity of the distance piece 120 that is positioned at neighboring area 112b.With Figure 1A is example, and the quantity that is positioned at the distance piece 120 of neighboring area 112b is 28, and the quantity that is positioned at the distance piece 120 of middle section 112a is 30, thereby M and N satisfy the condition of M ≧ N.

But, what must illustrate is that in other embodiments, M and N also can satisfy the condition of N ≧ M, so be positioned at the quantity of distance piece 120 of middle section 112a and the quantity of distance piece 120 that is positioned at neighboring area 112b among Figure 1A, and non-limiting the utility model only for illustrating.

The area size of middle section 112a is X, and the area of neighboring area 112b size is Y, so X and Y are all greater than zero.X and Y can satisfy the condition of Y ≧ X, and promptly the area of neighboring area 112b can be greater than the area of middle section 112a.With Figure 1A is example, plate face 112 is essentially rectangle, and be divided into nine palace lattice, wherein middle section 112a is the grid of central authorities, remaining grid forms neighboring area 112b, therefore the ratio of neighboring area 112b and the two area of middle section 112a is essentially 8:1, and promptly the ratio of Y and X equals 8 in fact.

But, the area of neighboring area 112b also can be less than the area of middle section 112a.For instance, plate face 112 also can adopt alternate manner to come five equilibrium, for example plate face 112 is divided into four and takes advantage of four or five grid of taking advantage of five equal matrix to arrange, so the two area size and ratio of middle section 112a shown in Figure 1A and neighboring area 112b do not limit the utility model only for illustrating.

What deserves to be mentioned is that in the present embodiment, the arrangement of distance piece 120 can be applicable to contact panel, so above X, Y, M and N more can satisfy following mathematical expression (1):

………………………………………（1）

From mathematical expression (1), can learn, the quantity of the distance piece 120 in the unit area in middle section 112a (unit area) can be more than or equal to the quantity of the distance piece in the unit area in the 112b of neighboring area 120, and promptly the distribution density (distribution density) of distance piece 120 in middle section 112a can be more than or equal to the distribution density in the 112b of neighboring area.Therefore, the distance piece 120 in the middle section 112a distributes more intensive than the distance piece in the 112b of neighboring area 120, to meet the more demand of contact panel middle section touching, shown in Figure 1A.

Figure 1B is the diagrammatic cross-section that I-I section along the line is drawn among Figure 1A.See also Figure 1B, the shape of these distance pieces 120 can be in fact a column, and each distance piece 120 can have an end face 122 and a bottom surface 124, and wherein end face 122 is with respect to bottom surface 124, and bottom surface 124 can be contacted with plate face 112.In addition, each distance piece 120 can be 124 towards end face 122 convergents, shown in Figure 1B from the bottom surface.

The shape of these distance pieces 120 can be mutually the same, perhaps also can be to be not quite similar, so the shape of one of them distance piece 120 can be different from the shape of another distance piece 120.For instance, in Figure 1B, can find out that obviously one of them distance piece 120(for example comes second distance piece 120 from the right number) the area of end face 122 be positioned at rightmost distance piece 120 less than another distance piece 120() the area of end face 122.

In addition, the height of these distance pieces 120 also can be not quite similar.With Figure 1B is example, and one of them distance piece 120(is positioned at rightmost distance piece 120) height H 1 for example come second distance piece 120 less than another distance piece 120(from the right number) height H 2.

In sum, these included distance pieces of substrate with display of no periodic array distance piece of the present utility model can be as the support member between a flat board (as active assembly array substrate) and another flat board (colored optical filtering substrates), so that these two states that flat board remains apart.So, can keep between these two flat boards and have a gap (gap), be subjected to the compressing of these flat boards with the liquid crystal material of avoiding being positioned at the gap, and then prevent that liquid crystal material from spilling.

In addition, because the distance piece in the middle section distributes can be more intensive than the distance piece in the neighboring area, and the quantity that is positioned at the distance piece of middle section can be more than or equal to the quantity of the distance piece that is positioned at the neighboring area, therefore the utility model can be under a limited number of conditions of distance piece, strengthen the voltage endurance capability of display panels central part and the recovery capability behind the pressurized, also can avoid taking place simultaneously the problem that liquid crystal material contains quantity not sufficient.So, when display panels is in low temperature environment (Celsius temperature is lower than 0 ℃), the utility model can reduce to catch a cold because of liquid crystal material and shrinks probability that bubbles of vacuum occurs.

Though the utility model with previous embodiment openly as above; right its is not in order to limiting the utility model, anyly has the knack of alike skill person, in not breaking away from spirit and scope of the present utility model; the equivalence of doing to change with retouching is replaced, and still is in the scope of patent protection of the present utility model.
