FIG. 1A is a schematic top view of a display panel according to at least one embodiment of the present invention, and FIG. 1B is a schematic cross-sectional view along the line 1B-1B in FIG. 1A. Referring to FIGS. 1A and 1B, the display panel 100 includes a first substrate 110, a second substrate 120 and a filling material 150. The second substrate 120 is opposite to the first substrate 110. That is, the second substrate 120 is disposed on the opposite side of the first substrate 110, and the first substrate 110 and the second substrate 120 may face each other, wherein the filling material 150 is disposed between the first substrate 110 and the second substrate 120 , As shown in Figure 1B.

In this embodiment, the display panel 100 may be a liquid crystal display panel, wherein the first substrate 110 may be an element array substrate and has a plurality of control elements (not shown), such as thin film transistors (TFT). The second substrate 120 may be a color filter substrate, and has a black matrix (not shown) and a plurality of filter layers (not shown), where the filter layers are, for example, a red filter layer and a green filter layer. With blue light filter layer.

The second substrate 120 may also be an opposite substrate without any filter layer, so the second substrate 120 is not limited to only a color filter substrate. In addition, in other embodiments, the first substrate 110 may also be the above-mentioned color filter substrate or the counter substrate, and the second substrate 120 may also be the above-mentioned element array substrate. Therefore, the first substrate 110 is not limited to an element array substrate, and the second substrate 120 is not limited to a color filter substrate or a counter substrate.

The display panel 100 may include a sealant 160, where the sealant 160 is disposed between the first substrate 110 and the second substrate 120. The sealant 160 may have adhesiveness, so the sealant 160 can connect the first substrate 110 and the second substrate 120, so that the first substrate 110 and the second substrate 120 can be combined together. The filling material 150 may be a liquid crystal material, which is a fluid material, so the filling material 150 has fluidity. The sealant 160 surrounds the filling material 150 to limit the filling material 150 and prevent the filling material 150 from leaking.

The display panel 100 further includes a plurality of support members 130 and a plurality of partition members 141 and 142. The support members 130 and the partition members 141 and 142 are located between the first substrate 110 and the second substrate 120. The support members 130 and the partition members 141, 142 are arranged together in a mesh structure N10 between the first substrate 110 and the second substrate 120, wherein the mesh structure N10 is mainly distributed in the display area of the display panel 100 (not shown) , And the image displayed on the display panel 100 will appear in the display area. The sealant 160 surrounds the mesh structure N10, so that the sealant 160, the first substrate 110 and the second substrate 120 can seal the mesh structure N10 and the filling material 150.

The mesh structure N10 has a plurality of meshes N1a and a plurality of connected gaps N1b, wherein the meshes N1a are openings of the mesh structure N10 and are regularly distributed in the mesh structure N10. Taking FIG. 1A as an example, the grids N1a can be arranged in an array, and one of the partitions 141 and 142 and each support 130 can be located around one of the grids N1a.

In the embodiment shown in FIG. 1A, the shapes of each partition 141 and each partition 142 are both strips. The partition 141 extends along the first direction D1, and the partition 142 extends along the second direction D2, where the first direction D1 is different from the second direction D2. Taking FIG. 1A as an example, the first direction D1 and the second direction D2 are substantially perpendicular, where the first direction D1 may be a horizontal direction, and the second direction D2 may be a vertical direction. However, in other embodiments, the first direction D1 may be a vertical direction, and the second direction D2 may be a horizontal direction.

Therefore, some of these partitions (ie, the partition 141) extend along the first direction D1, and the other these partitions (ie, the partition 142) extend along the second direction D2. In addition, in the display panel 100 shown in FIG. 1A, the partitions 141 are further arranged in multiple rows along the first direction D1, and the partitions 142 are further arranged in multiple rows along the second direction D2.

From FIG. 1A, two of the partitions 141 extending along the first direction D1 and two of the partitions 142 extending along the second direction D2 will surround a grid N1a, and each support 130 is located on the grid. At the corners of N1a, one of the partitions 141 and 142 and each support 130 are located around one of the grids N1a.

The partitions 141 and 142 can be made of the same material. For example, the spacers 141 and 142 can be formed by the same layer of photoresist layer after exposure and development, that is, the spacers 141 and 142 can be a layer of photoresist pattern after development, and the thickness of the spacers 141 and 142 can be substantially Are equal to each other. However, in other embodiments, the thickness of at least two of the partitions 141 and 142 may not be equal.

Each communication gap N1b is formed between the adjacent support member 130 and the partition member 141, or between the adjacent support member 130 and the partition member 142. Each communication slit N1b communicates with at least one mesh N1a so that the meshes N1a can communicate with each other via these communication slits N1b. Therefore, a filling material 150 with fluidity (for example, a liquid crystal material) can flow between the meshes N1a through the communication gaps N1b. In this way, by using these communicating gaps N1b, the filling material 150 can fill the grids N1a and at least one communicating gap N1b, so that the filling material 150 can be evenly distributed in the display panel 100, reducing or avoiding the occurrence of grid N1a defects. When it is filled with the filling material 150, the image quality is maintained.

The partitions 141 and 142 do not contact the support 130 to ensure that a communication gap N1b is formed between the adjacent support 130 and one of the partitions 141 and 142. However, it should be noted that in other embodiments, even if the support 130 is in contact with the partition 141 (or 142), the communication gap N1b can still be formed between the adjacent support 130 and the partition 141 (or 142). .

Taking FIG. 1A as an example, a plurality of partitions 141 and 142 adjacent to each other can surround one of the supporting members 130, wherein the supporting member 130 can be surrounded by two adjacent partitions 141 and two adjacent partitions 142. The two adjacent partitions 141 and the adjacent two partitions 142 can be arranged in a cross shape, and the support 130 can be located in the center of the cross, so at least one support 130 can be divided by four adjacent partitions 141. Surrounded with 142.

When the support 130 is in contact with one of the partitions 141 or 142, a communication gap N1b can still be formed between the support 130 and the other adjacent partitions 141 or 142. For example, when the support 130 is in contact with the partition 141 on the right side, a communication gap N1b may still be formed between the support 130 and the partition 141 adjacent to the left. It can be seen that even if the support 130 is in contact with the partition (the partition 141 or 142), a communication gap N1b can still be formed around the support 130.

FIG. 1C is a schematic top view of the display panel in FIG. 1A after the second substrate, spacers and filling materials are removed. Please refer to FIG. 1B and FIG. 1C. The support members 130 may be disposed on the first substrate 110, and the support members 130 may be formed of the same film layer. For example, the support members 130 may be formed by the same layer of photoresist layer after exposure and development, that is, the support members 130 may be a layer of photoresist pattern after development. The support members 130 may be arranged in an array without contacting each other, and the thickness of the support members 130 may be substantially equal to each other, as shown in FIGS. 1B and 1C.

The support 130 may contact the first substrate 110 and the second substrate 120, and may serve as a spacer in the liquid crystal display panel. Therefore, the support members 130 can support the first substrate 110 and the second substrate 120 to maintain the distance between the first substrate 110 and the second substrate 120. In this way, the support 130 helps to generate a suitable electric field between the first substrate 110 and the second substrate 120 to drive the liquid crystal molecules of the liquid crystal material (ie, the filling material 150) to deflect, so as to maintain or improve the image quality of the display panel 100.

In this embodiment, the sealant 160 may be formed on the first substrate 110 first. Afterwards, a filling material 150 (for example, a liquid crystal material) is formed in the area surrounded by the sealant 160 on the first substrate 110, wherein the filling material 150 can be formed on the first substrate by using the liquid crystal drop method (One Drop Fill, ODF) 110 on. Then, the second substrate 120 is pressed to the first substrate 110, and the sealant 160 is connected to the first substrate 110 and the second substrate 120, so that the first substrate 110 and the second substrate 120 are combined together, and the filling material 150 and the mesh structure N10 are sealed between the first substrate 110 and the second substrate 120. So far, the display panel 100 is basically completed.

FIG. 1D is a schematic top view of the display panel in FIG. 1A after the first substrate, the supporting member, the filling material, and the sealant are removed. 1B and 1D, the spacers 141 and 142 can be disposed on the second substrate 120, and can be formed by the same photoresist layer after exposure and development, wherein the spacers 141 and 142 are not in contact with each other. At least one of the spacers 141 and 142 may not contact the first substrate 110. For example, none of these spacers 142 contact the first substrate 110.

However, it should be noted that in other embodiments, all the partitions 141 and 142 can contact the first substrate 110. Therefore, FIG. 1B is for illustration only, and it is not a limitation that the spacers 141 and 142 cannot contact the first substrate 110. In addition, the partitions 141 and 142 may be arranged in a net shape to arrange the basic outline of the net structure N10. For example, the partitions 141 and 142 may form a plurality of grids N1a, as shown in FIG. 1D.

2A is a schematic top view of a display panel according to another embodiment of the invention. Referring to FIG. 2A, the display panel 200 of this embodiment is similar to the display panel 100 of the previous embodiment, and the cross-sectional structure of the two is substantially the same. Therefore, the same features of the display panels 100 and 200 will not be repeated in principle, and the cross-sectional structure of the display panel 200 will not be shown. The main difference between the display panels 100 and 200 is that the arrangement of the support 130 of the display panel 200 is different from the arrangement of the support 130 of the display panel 100, and the plurality of partitions of the display panel 200 includes a plurality of cross-shaped partitions 241 , Its shape is different from that of the partitions 141 and 142.

2B is a schematic top view of the display panel in FIG. 2A after removing the second substrate, the spacer, the filling material, and the sealant. Please refer to FIGS. 2A and 2B. Different from the aforementioned display panel 100, in the display panel 200, the support members 130 are arranged alternately with each other. Taking FIGS. 2A and 2B as an example, the connection line between two adjacent support members 130 is not parallel to the first direction D1 and the second direction D2, and the connection line is basically parallel to the first direction D1 and the second direction D2. The angle bisector direction D3 between the two directions D2.

FIG. 2C is a schematic top view of the display panel in FIG. 2A after the first substrate, the supporting member, and the filling material are removed.

These cross-shaped partitions 241 are arranged alternately with each other, and a grid N2a is formed between two adjacent cross-shaped partitions 241. Taking FIG. 2A and FIG. 2C as an example, these cross-shaped partitions 241 can be arranged along the direction D3 of the bisector of the angle. Among the cross-shaped partitions 241 arranged in the direction D3 of the angle bisector, a grid N2a can be formed between two adjacent cross-shaped partitions 241, that is, a grid N2a can be located between two adjacent cross-shaped partitions. Between pieces 241.

The display panel 200 may further include a plurality of T-shaped partitions 242. The T-shaped partitions 242 may be adjacent to the sealant 160 and located around the cross-shaped partitions 241, wherein the T-shaped partitions 242, the cross-shaped partitions 241, and the support members 130 may be arranged together to form a net structure N20 , And the mesh structure N20 not only has a plurality of meshes N2a, but also a plurality of connected gaps N1b. In addition, different from the foregoing embodiment, the sealant 160 in this embodiment may be formed on the second substrate 120 first, as shown in FIG. 2C.

Since the shape of the T-shaped partition 242 is T-shaped, each T-shaped partition 242 has a middle convex portion 242 a, and the middle convex portions 242 a of the T-shaped divider 242 can all extend toward the cross-shaped divider 241. Therefore, the middle convex portion 242 a of each T-shaped partition 242 basically extends toward the display area and the cross-shaped partition 241. In addition, although the display panel 200 in the embodiment of FIG. 2A includes these T-shaped partitions 242, in other embodiments, the display panel 200 may not include the T-shaped partitions 242. Therefore, as shown in FIGS. 2A and 2C The T-shaped partition 242 is for illustration only, and does not limit the present invention.

3A is a schematic top view of a display panel according to another embodiment of the invention. Referring to FIG. 3A, the display panel 300 of this embodiment is similar to the display panels 100 and 200 of the previous embodiment. However, different from the display panels 100 and 200 of the foregoing embodiments, the support members 330 and the partitions 340 included in the display panel 300 are different from the support members 130 and the partitions of the foregoing embodiment in shape and arrangement. 141, 142, a cross-shaped partition 241, and a T-shaped partition 242.

Specifically, the partitions 340 and the support members 330 are both strip-shaped in shape, wherein the partitions 340 all extend along the first direction D1, and the support members 330 all extend along the second direction D2. Therefore, the directions of the partitions 340 are the same as each other, and the directions of the support members 330 are also the same with each other, but the direction of the partitions 340 is different from the direction of the support 330. Since the first direction D1 and the second direction D2 are substantially perpendicular, the support members 330 may be substantially perpendicular to the partition members 340, as shown in FIG. 3A.

3B is a schematic cross-sectional view taken along the line 3B-3B in FIG. 3A. Please refer to FIGS. 3A and 3B. In this embodiment, the thickness of two of the support members 330 is not the same, and the thickness of two of the partitions 340 is not the same. Taking FIG. 3B as an example, FIG. 3B shows two partitions 340 and three support members 330 with significantly different thicknesses, wherein the thickness of the two support members 330 is substantially equal, and the thickness is significantly greater than the thickness of the other support member 330, and The two support members 330 with substantially the same thickness both contact the first substrate 110 and the second substrate 120.

However, it should be noted that in other embodiments, the thickness of the support members 330 may be substantially equal to each other, and the thickness of the partition members 340 may also be substantially the same, and even the support members 330 and the partition members 340 may be both. The first substrate 110 and the second substrate 120 are contacted. Therefore, the support 330 and the partition 340 shown in FIG. 3B are for illustration only, and the thickness of the support 330 and the partition 340 are not limited.

Among the support members 330 arranged in a row along the second direction D2, a gap G33 is formed between two adjacent support members 330. Since the supporting members 330 are arranged staggered with each other, the gaps G33 are also staggered with each other, as shown in FIG. 3C.

Please refer to FIG. 3D. Similarly, the spacers 340 are disposed on the second substrate 120 and are also arranged in a staggered manner. Among the partitions 340 arranged in a row along the first direction D1, a gap G34 is formed between two adjacent partitions 340. Since the spacers 340 are arranged staggered with each other, the gaps G34 are also staggered with each other, as shown in FIG. 3D.

3A, 3C, and 3D, after the first substrate 110 and the second substrate 120 are connected to each other by the sealant 160, one of the support members 330 is located in the gap G34 between the two adjacent partitions 340, and A partition 340 is located in the gap G33 between two adjacent support members 330. Therefore, one of the support members 330 is located between two adjacent partitions 340, and one of the partitions 340 is located between two adjacent support members 330. In addition, the partitions 340 and the support 330 may be alternately arranged along the first direction D1 or the second direction D2, as shown in FIG. 3A.

Since the direction of the partitions 340 is different from the direction of the support members 330, one of the support members 330 is located between two adjacent partitions 340, and one of the partitions 340 is located between two adjacent support members 330. Therefore, the partitions 340 and the support members 330 can also be arranged together to form a network structure N30, which has a plurality of grids N3a and a plurality of communicating gaps N3b, wherein each of the communicating gaps N3b is also formed in the adjacent supporting member Between 330 and the partition 340, these meshes N3a can also communicate with each other through these communication gaps N3b. In this way, the filling material 150 can also fill the grids N3a through at least one communicating gap N3b.

4A is a schematic top view of a display panel according to another embodiment of the present invention, and FIG. 4B is a schematic cross-sectional view along the line 4B-4B in FIG. 4A. Please refer to FIGS. 4A and 4B. The display panel 400 of this embodiment is similar to the display panel 100 of the previous embodiment, and only the differences between the display panels 100 and 400 are described below.

Specifically, the display panel 400 includes a plurality of connection layers 470, wherein the connection layers 470 are disposed on the second substrate 120 and connect the spacers 141 and 142. The constituent material of the connection layer 470 may be the same as that of the spacers 141 and 142, and the connection layer 470 and the spacers 141, 142 can be formed by photoresist. For example, both the connection layer 470 and the spacers 141 and 142 can be formed by two layers of photoresist through exposure and development twice. Alternatively, the connection layer 470 and the spacers 141, 142 can also be formed by the same photoresist layer after exposure and development, wherein the aforementioned exposure can be a half-tone mask or a gray-scale mask. mask), so the connecting layer 470 and the spacers 141 and 142 can be integrally formed.

The connection layers 470 are respectively located in the grids N1a and may not contact the support members 130. The thickness of at least one partition 141 or 142 may be greater than the thickness of each connection layer 470. Taking FIG. 4B as an example, the respective thicknesses of each partition 141 and each partition 142 are greater than the thickness of each connection layer 470, wherein the thickness of the connection layers 470 may be substantially equal to each other, as shown in FIG. 4B. However, in other embodiments, the thicknesses of two adjacent connecting layers 470 may not be equal to each other, so the thicknesses of these connecting layers 470 are not limited to be substantially equal to each other.

In addition, in this embodiment, the partitions 141 and 142 may contact the first substrate 110 and the second substrate 120, as shown in FIG. 4B. However, in other embodiments, at least one of the partitions 141 and 142 may not contact the first substrate 110, so FIG. 4B is for illustration only, and it is not limited that the partitions 141 and 142 must contact the first substrate 110.

Referring to FIG. 5, in the embodiment shown in FIG. 4B, the respective thicknesses of each partition 141 and each partition 142 are greater than the thickness of each connection layer 470, but in the display panel 500 shown in FIG. 5, The thickness of the at least one spacer 540 may be less than the thickness of each connection layer 570, wherein the thickness of the connection layers 570 may be substantially equal to each other, as shown in FIG. 5.

However, in other embodiments, the thickness of two adjacent connecting layers 570 may not be equal to each other, so the thickness of these connecting layers 570 is not limited to be substantially equal to each other. In addition, in the embodiment shown in FIG. 5, the connection layer 570 does not contact the first substrate 110, but in other embodiments, the connection layer 570 can contact the first substrate 110 and the second substrate 120, so the connection layer 570 does not It is restricted that the first substrate 110 cannot be contacted.

The arrangement of the plurality of partitions 540 (only one is shown in FIG. 5) included in the display panel 500 may be the same as the partitions 141 and 142 shown in FIG. 4A. The only difference between the partitions 141 and 142 in FIG. 4A is that the partition 540 in FIG. 5 has a thinner thickness, so the partition 540 does not contact the first substrate 110, as shown in FIG.

In particular, the connection layers 470 and 570 disclosed in FIGS. 4A, 4B, and 5 above can also be disposed on the mesh N2a in FIG. 2A and the mesh N3a in FIG. 3A. Therefore, the connection layers 470 and 570 are not limited to be applied to the display panel 400 in FIGS. 4A and 4B and the display panel 500 in FIG. 5.

6A is a schematic top view of a display panel according to another embodiment of the present invention, and FIG. 6B is a schematic cross-sectional view along the line 6B-6B in FIG. 6A. 6A and 6B, different from the display panels 100 to 500 of the foregoing embodiments, the display panel 600 of this embodiment is a self-luminous display panel instead of a liquid crystal display panel, and the display panel 600 may be a light-emitting diode Display panel. The display panel 600 not only includes a first substrate 610, a second substrate 620, and a filling material 650, but also includes a plurality of light emitting elements 690. However, the display panel 600 may not include the sealant 160.

The light-emitting elements 690 are disposed between the first substrate 610 and the second substrate 620. The light-emitting elements 690 can be mounted on the first substrate 610 and electrically connected to the first substrate 610. The first substrate 610 may be an element array substrate and has a plurality of control elements (not shown), such as thin film transistors (TFT). The display panel 600 further includes a plurality of filter layers 680r, 680g, and 680b, and the filter layers 680r, 680g, and 680b are disposed on the second substrate 620. The second substrate 620 is a transparent substrate, such as a glass plate or a transparent substrate. Plastic board. In addition, the light-emitting elements 690 and the filter layers 680r, 680g, and 680b are located between the first substrate 610 and the second substrate 620, as shown in FIG. 6B.

Each light-emitting element 690 is suitable for emitting light L6, and the filling material 650 is a wavelength conversion layer, and can convert the wavelength of the light L6 emitted by these light-emitting elements 690. For example, each light-emitting element 690 may be a blue light-emitting diode and can emit blue light L6. The filling material 650 can convert the wavelength of the light L6, for example, convert the light L6 into yellow light.

The filling material 650 is actually difficult to convert all the light L6 into yellow light, so part of the light L6 can penetrate the filling material 650 without substantially changing the wavelength, so that the blue light L6 can be converted into the filling material 650 The yellow light combines to form white light. Therefore, when the light-emitting elements 690 emit blue light L6, the light L6 can be converted into white light after passing through the filling material 650.

The white light mentioned above will be incident on the filter layers 680r, 680g, and 680b, and various colors of light have been generated. For example, the filter layers 680r, 680g, and 680b can be a red filter layer, a green filter layer, and a blue filter layer, respectively, and can filter the white light from the filling material 650 into red light, green light, and Blu-ray. Therefore, the light L6 emitted by each light-emitting element 690 will sequentially pass through the wavelength conversion layer (that is, the filling material 650) and one of the filter layers 680r, 680g, and 680b, and be filtered out by the filter layers 680r, 680g, and 680b. In the red, green and blue light, the display panel 600 can display images.

The display panel 600 further includes a plurality of partitions 640 and a plurality of support members 130. The partitions 640 may be disposed on the second substrate 620, and the support members 130 may be disposed on the first substrate 610, wherein the support members 130 and the partitions 640 may be located between the first substrate 610 and the second substrate 620. The shape and arrangement of the partitions 640 can be substantially the same as the shape and arrangement of the partitions 141 and 142 in FIG. A grid N6a and a plurality of communication slits N6b, and each communication slit N6b is also formed between the adjacent support member 130 and the partition member 640.

The filter layers 680r, 680g, and 680b can be located in the grids N6a, respectively. Therefore, each of the filter layers 680r, 680g, and 680b located in the grids N6a can be used as a sub-pixel of the display panel 600. ). In addition, the color of these partitions 640 may be dark, such as black. In this way, these partitions 640 can act as a black matrix and have a light-shielding function.

The filling material 650 may be formed by curing a fluid wavelength conversion material, where the wavelength conversion material is, for example, a fluorescent material or a quantum dot material. These grids N6a can also communicate with each other through these communicating gaps N6b. Therefore, in the process of forming the filling material 650, the wavelength conversion material can flow to the grids N6a through these communicating gaps N6b, and fill the grids N6a and at least A connecting gap N6b allows the filling material 650 to be evenly distributed in the display panel 600 to maintain or improve the image quality.

After the wavelength conversion material fills the grids N6a and at least one communication gap N6b, the wavelength conversion material is cured to form a solid filling material 650, where the wavelength conversion material may be a thermal curing or light curing material. In addition, these partitions 640 may not contact the first substrate 610, as shown in FIG. 6B. Or, in other embodiments, at least one of these partitions 640 may contact the first substrate 610.

In particular, in the display panel 600 shown in FIG. 6A, the partition 640 can be replaced with the cross-shaped partition 241 and the T-shaped partition 242 in FIG. 2A, or the partition 340 in FIG. 3A. When the partition 640 in FIG. 6A is replaced with the partition 340 in FIG. 3A, the support 130 in FIG. 6A can be replaced with the support 330 in FIG. 3A. Therefore, the display panel 600 is not limited to the use of the partition 640 and the support 130 as shown in FIGS. 6A and 6B. The partition and support 130 disclosed in the foregoing embodiment can also be applied to the display panel 600 of this embodiment. .

In summary, since multiple grids in the network structure can be connected to each other through one or more communication gaps, filling materials (such as liquid crystal materials or uncured wavelength conversion materials) can be connected to these grids through the communication gaps. Flow between the grids so that the filling material can fill the grids and at least one communicating gap. It can be seen that the above-mentioned connecting gap helps to reduce or avoid the occurrence of grids not being filled with the filling material, thereby helping the filling material to be evenly distributed in the display panel to maintain or improve the image quality.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Those with ordinary knowledge in the technical field of the present invention can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the present invention The scope of invention protection shall be subject to the scope of the attached patent application.
