Fig. 1 is a schematic top view of a display device according to an embodiment of the disclosure. Several elements are omitted from fig. 1 for clarity and ease of illustration. Fig. 2 isbase:Sub>A schematic cross-sectional view of the display device of fig. 1 along the sectional linebase:Sub>A-base:Sub>A'. Several elements are omitted from fig. 2 for clarity of the drawing and ease of illustration. Referring to fig. 1 and 2, a display device 10 of the present disclosure includes a first assembly 100 and a plurality of second assemblies 200. A plurality of second assemblies 200 are disposed on the first assembly 100. In the present embodiment, the first component 100 includes a cover plate or a color filter substrate, for example. Each second component 200 for example comprises a display panel. Under the above configuration, the first assembly 100 and the second assembly 200 can be separately fabricated, and then the plurality of second assemblies 200 can be directly assembled on the first assembly 100, so that the fabrication process of the display device 10 can be simplified, or the fabrication cost can be reduced. In addition, since a plurality of display panels (e.g., the second assembly 200) can be directly disposed on a cover plate and/or a color substrate (e.g., the first assembly 100), the bezel size of the display panel can be reduced. Therefore, the display device 10 can achieve a seamless splicing visual effect or have good display quality.

The splicing method of the present embodiment will be briefly described below with reference to fig. 1 and 2. First, a first assembly 100 is provided. As shown in fig. 2, the first assembly 100 includes a first substrate 110 and a first light shielding structure 120 disposed on the first substrate 110. The first light shielding structure 120 has a plurality of first openings 122. In the present embodiment, the first substrate 110 includes a rigid substrate or a flexible substrate, for example. For example, the material of the first substrate 110 may include glass, quartz, sapphire (sapphire), ceramic, polycarbonate (PC), polyimide (PI), polyethylene terephthalate (PET), other suitable substrate materials, or a combination thereof, but is not limited thereto. The first light shielding structure 120 is, for example, a black matrix (black matrix) having a light shielding effect and a low reflection characteristic. For example, the material of the first light shielding structure 120 may include metal or opaque resin doped with pigment, or other suitable materials or combinations thereof, but is not limited thereto. The metal may be, for example, chromium (Cr), but is not limited thereto. The resin may be, for example, epoxy resin (epoxy resin) or acrylic resin (acrylic resin), or other suitable materials or combinations of the above materials, but is not limited thereto.

Next, a plurality of second components 200 are provided. Each of the second elements 200 includes a second substrate 210 and a plurality of leds 260 disposed on the second substrate 210. The second substrate 210 includes a rigid substrate or a flexible substrate, for example. For example, the material of the second substrate 210 may include glass, quartz, sapphire (sapphire), ceramic, polycarbonate (PC), polyimide (PI), polyethylene terephthalate (PET), other suitable substrate materials, or a combination thereof, but is not limited thereto. The light emitting diodes 260 include, for example, a red light emitting diode 261, a green light emitting diode 262, and a blue light emitting diode 263, but not limited thereto. That is, the second element 200 of the present embodiment includes, for example, a display panel (display panel) having a function of displaying images, but the disclosure is not limited thereto.

Then, the optical adhesive layer 300 is disposed on the first assembly 100 and between the second assembly 200, for example, the optical adhesive layer 300 may be disposed on the first assembly 100, or in another implementation, the optical adhesive layer 300 may be disposed on the second assembly 200. The second assembly 200 can be attached or fixed to the first assembly 100 by disposing the optical adhesive layer 300 between the first assembly 100 and the second assembly 200. The material of the optical adhesive layer 300 may be Optical Clear Adhesive (OCA) with viscosity, optical Clear Resin (OCR), or other suitable material or combination of the above materials, but is not limited thereto. When the optical adhesive layer 300 is an optically transparent resin, the viscosity thereof is, for example, 10mPa · s to 100mPa · s, but the disclosure is not limited thereto.

In some embodiments, the display device 10 further comprises a barrier material (dam). A blocking material (not shown) may be disposed on the first component 100 or the second component 200. The barrier may be surrounded along the edges of the first component 100. Alternatively, the barrier may be surrounded along the edges of the second member 200. Under the above arrangement, the optical adhesive layer 300 can be fixed between the first assembly 100 and the second assembly 200 by the surrounding of the blocking material, and is not easy to overflow. The material of the barrier material includes, but is not limited to, a high-viscosity glue material or other suitable materials. When the blocking material is disposed on the second assembly 200, the blocking material may also be a transparent adhesive material with high transmittance (transparency), but not limited thereto. In this way, the display device 10 can have good display quality.

Next, as shown in fig. 1, a plurality of second assemblies 200 may be arranged in the directions of the X-axis and the Y-axis to be spliced on the first assembly 100. For example, in the X-axis, the second assembly 201 and the second assembly 202 may be adjacently spliced on the first assembly 100. In the present disclosure, the X-axis may extend from left to right in a top view direction of the display device 10. The Y axis is perpendicular to the X axis and extends from top to bottom in the top view of the display device 10.

As shown in fig. 1, the display device 10 is, for example, a display device 10 with 4 × 4 display panels formed by splicing four second components 200 spliced on an X axis and four second components 200 spliced on a Y axis, but the disclosure is not limited thereto. In some embodiments, the display device may also be a 3x3,5x5 or other combination tiled display device.

In the present disclosure, a gap GP may be generated between the second component 201 and the second component 202 according to the design and requirement of the user. There may be a gap GP between any two adjacent second assemblies 200. This gap GP may also be referred to as a splice line.

It should be noted that the display device 10 of the present embodiment includes, for example, performing alignment (alignment) between the first component 100 and the second component 200 by way of through alignment or image recognition alignment. In a penetrating alignment manner, alignment marks AM may be formed on two opposite surfaces of the first component 100 and two opposite surfaces of the second component 200 by, for example, laser, and then the alignment marks AM on the first component 100 and the alignment marks AM on the second component 200 are aligned correspondingly, so that the corresponding alignment marks AM are overlapped to achieve alignment. As shown in fig. 1, the alignment marks AM may be disposed at four corners of an edge of the first module 100 (not shown, the first module 100 overlaps the plurality of spliced second modules 200) or at any position in the first module 100. In addition, the alignment marks AM may be disposed at four corners of an edge of each of the second elements 200, or at any position in the second elements 200, but the disclosure is not limited thereto. It should be noted that a part of the alignment mark AM overlaps the display area of the display device 10. However, the alignment mark AM on the first assembly 100 observed by the user may be formed on the first light shielding structure 120. In this way, the influence of the alignment mark AM on the display quality can be reduced.

In the manner of image recognition alignment, the image recognition system can recognize the surface features on the first component 100 by a camera (camera), and then dispose the second component 200 at the corresponding position on the first component 100 according to the recognized surface features to achieve alignment. Therefore, the penetrating alignment or the image recognition alignment can achieve excellent alignment effect of the first component 100 and the second component 200. In this way, the second assembly 200 can be assembled on the first assembly 100 to obtain a good quality display device 10.

The structure of the display device 10 of the present embodiment will be briefly described below with reference to fig. 1 and 2.

Referring to fig. 2, fig. 2 shows a cross-sectional view of two second assemblies 200 spliced to the first assembly 100. In the present embodiment, the first assembly 100 includes a first substrate 110 and a first light shielding structure 120 disposed on the first substrate 110. The first light shielding structure 120 has a plurality of first openings 122. That is, the first element 100 may include a plurality of black matrixes, but the disclosure is not limited thereto.

The second assembly 200 includes a second assembly 201 and a second assembly 202. The second module 201 and the second module 202 are aligned and then disposed on the first module 100. The second component 201 and the second component 202 have a gap GP therebetween. In the present embodiment, the width of the gap GP in the X-axis direction can be determined according to the design and requirement of the user, such as 0 μm to 200 μm, but not limited thereto.

In the present embodiment, each of the second elements 200 further has a second spacer 240. The second spacer 240 is disposed on the second substrate 210. For example, the material of the second spacer layer 240 may include acrylic resin (acryl resin), siloxane (siloxane), a photoresist material, or other suitable materials or combinations thereof, but is not limited thereto. The second spacer 240 has a plurality of fourth openings 242.

The plurality of light emitting diodes 260 are disposed in the plurality of fourth openings 242, respectively. For example, the red led 261, the green led 262 and the blue led 263 may be disposed in the corresponding fourth openings 242, respectively. The plurality of fourth openings 242 correspond to the plurality of first openings 122, respectively. Thereby, the light emitting diode 260 positioned in the fourth opening 242 may correspond to a portion of the first opening 122. That is, the plurality of light emitting diodes 260 are disposed corresponding to portions of the plurality of first openings 122.

For example, the light emitting diode 260 may overlap the first opening 122 by 20% to 100% with a tolerance of ± 10%, such as 20% ± 10%, 40% ± 10%, 60% ± 10%, 80% ± 10% or 100%, but not limited thereto, in a Z-axis direction perpendicular to the first component 110. In this way, the light emitted by the light emitting diode 260 can pass through the first opening 122 and pass out of the first component 100.

In the present embodiment, the width W1 of the first opening 122 and the width W4 of the fourth opening 242 may be the same or different. For example, the width W1 may be greater than or equal to the width W4, but not limited thereto. In some embodiments, the width W1 may also be less than the width W4. In the present disclosure, the width W1 may be defined as the maximum width of the first opening 122 on the X axis, wherein the width W1 is measured in the cross-sectional direction of the first opening 122 of the first light shielding structure 120, and the distance between two sides of the first opening 122 on the X axis is measured. The width W4 may be defined as the maximum width of the fourth opening 242 on the X axis, wherein the width W2 is measured in the cross-sectional direction as illustrated in the present embodiment, and the distance between two sides of the fourth opening 242 on the X axis in the second spacer layer 240 is measured. In the present disclosure, the X axis is parallel to the extending direction of the first component 100 and perpendicular to the Z axis. Under the above arrangement, the portion of the led 260 corresponding to the first opening 122 can be lifted to have good display quality.

In this embodiment, the optical adhesive layer 300 of the display device 10 is disposed between the first component 100 and the second component 201. The optical adhesive layer 300 is also disposed between the first assembly 100 and the second assembly 202. The optical adhesive layer 300 may also be partially located in the gap GP between the second assembly 201 and the second assembly 202, but the disclosure is not limited thereto. In addition, the optical adhesive layer 300 may be disposed in the first opening 122 to further increase the contact area or enhance the bonding force. Thus, the display device 10 has good reliability.

It is noted that in the present embodiment, the portion of the first light shielding structure 120 corresponds to the gap GP between any two second elements 200. For example, in the Z-axis, the portion of the first light shielding structure 120 corresponding to the gap GP may overlap the gap GP between the second component 201 and the second component 202. That is, in the X axis, the width of the portion of the first light shielding structure 120 corresponding to the gap GP may be greater than or equal to the width of the gap GP, but the embodiment is not limited thereto. Thus, when the user views the first component 100, the portion of the first shading structure 120 can shade the gap GP (also referred to as a splicing line) between two adjacent second components 200. Therefore, the splicing line between two adjacent second assemblies 200 is not easy to be observed by a user, and the seamless splicing visual effect can be achieved. Therefore, the display device 10 can have good display quality or visual effect.

Other examples will be listed below for illustration. It should be noted that the following embodiments follow the reference numerals and parts of the contents of the foregoing embodiments, wherein the same reference numerals are used to indicate the same or similar elements, and the description of the same technical contents is omitted. For the description of the omitted parts, reference may be made to the foregoing embodiments, and the following embodiments will not be repeated.

Fig. 3 is a schematic cross-sectional view of a display device according to another embodiment of the disclosure. The display device 10A of the present embodiment is substantially similar to the display device 10 of fig. 2, and therefore the same and similar components in the two embodiments are not repeated here. The present embodiment is different from the display device 10 in that the first assembly 100A of the display device 10A further includes a first spacer layer 140 disposed on the first light shielding structure 120. In addition, the optical adhesive layer 300 is located between the first spacer layer 140 and the second spacer layer 240. In the present embodiment, the first spacer layer 140 may include a material with a reflective effect, such as mixed titanium dioxide (TiO) ₂ ) Or an acrylic resin of titanium dioxide and carbon black (carbon black), siloxane, photoresist material, or other suitable materials or combinations thereof, but the disclosure is not limited thereto.

The first spacer layer 140 has a plurality of second openings 142. The second openings 142 respectively correspond to the portions of the first openings 122 overlapping the first light shielding structure 120. Thereby, a portion of the second opening 142 corresponds to the light emitting diode 260 in the fourth opening 242. In the embodiment, the width W2 of the second opening 142 may be the same as or different from the width W1 of the first opening 122, and the embodiment is not limited thereto. In this embodiment, the width W2 may be greater than or equal to the width W4, but not limited thereto. In the present disclosure, the width W2 can be defined as the maximum width of the second opening 142 in the X-axis, wherein the width W2 is measured in the cross-sectional direction of the embodiment, and the distance between two sides of the second opening 142 of the first spacer layer 140 in the X-axis is measured.

The scattering layer 150 is disposed in at least one of the plurality of second openings 142. In addition, the scattering layer 150 is disposed in the first opening 122 corresponding to the second opening 142. Thus, one of the light emitting diodes 260 (e.g., the red light emitting diode 261, the green light emitting diode 262, or the blue light emitting diode 263) can be disposed corresponding to the scattering layer 150. In this embodiment, the material of the scattering layer 150 may include a resin layer containing a light scattering agent such as fine particles for scattering light, or other suitable materials or combinations of the above materials, but is not limited thereto. Thus, the light emitted from the light emitting diode 260 can be scattered or diffused by the scattering layer 150, thereby increasing the amount of visible light. Thus, the display device 10A can have good display quality or display effect.

In addition, since the scattering layer 150 is disposed in the second opening 142 of the first spacer layer 140, light emitted from the light emitting diode 260 can be reflected, so as to improve the utilization rate of the light. Alternatively, the first spacer layer 140 can limit the light traveling direction and reduce the probability of light mixing. In addition, since the scattering layer 150 is disposed in the first opening 122 of the first light shielding structure 120, the light emitting direction of the light emitting diode 260 can be increased, or the viewing angle of the display device 10 can be increased. In this way, the display device 10A can have good display quality or display effect. In addition, the display device 10A can also achieve excellent technical effects similar to those of the above-described embodiments.

Fig. 4 is a schematic cross-sectional view of a display device according to another embodiment of the disclosure. The display device 10B of the present embodiment is substantially similar to the display device 10A of fig. 3, and therefore, the same and similar components in the two embodiments are not repeated herein. The present embodiment is different from the display device 10A in that the first assembly 100B of the display device 10B further includes a second light shielding structure 160 disposed on the first spacer layer 140. The first spacer layer 140 is disposed between the first light shielding structure 120 and the second light shielding structure 160. The material of the second light shielding structure 160 is similar to that of the first light shielding structure 120, and includes, for example, a black matrix (black matrix) having a light shielding effect and a low reflection characteristic, or other suitable materials or combinations thereof, but is not limited thereto, and thus will not be described again.

In the present embodiment, the second light shielding structure 160 further has a plurality of fifth openings 162. The fifth opening 162 is disposed corresponding to a portion of the second opening 142. In addition, the fifth opening 162 is disposed corresponding to a portion of the first opening 122.

In the second assembly 200B (including the second assembly 201B and the second assembly 202B) in this embodiment, the plurality of light emitting diodes 260 are disposed on the second substrate 210 and correspond to the fifth opening 162, the second opening 142 and the portion of the first opening 122, so that the light emitting diodes 260 can be correspondingly located in the fifth opening 162 or in the fifth opening 162 and the second opening 142, but not limited thereto. In some embodiments, the top surface of the light emitting diode 260 away from the second substrate 210 may be located in the second opening 142. In other embodiments, the top surface of the light emitting diode 260 away from the second substrate 210 may be aligned with the interface of the first spacer layer 140 and the first light shielding structure 120, but is not limited thereto. Therefore, the utilization rate of light can be improved, or the probability of light mixing can be reduced. The display device 10B can have good display quality or display effect.

In the embodiment, the optical adhesive layer 300 may be further disposed in the fifth opening 162, the second opening 142 and the first opening 122 to further increase the contact area or enhance the bonding force. Thus, the display device 10B has good reliability.

In addition, since the provision of the second spacer can be omitted, the display device 10B can be further thinned. In addition, the display device 10B can also achieve excellent technical effects similar to those of the above-described embodiment.

Fig. 5 is a schematic cross-sectional view of a display device according to another embodiment of the disclosure. The display device 10C of the present embodiment is substantially similar to the display device 10A of fig. 3, and therefore the same and similar components in the two embodiments are not repeated here. The present embodiment is different from the display device 10A mainly in that the display device 10C further includes a color filter layer 130 and a light conversion unit 170. In addition, the plurality of light emitting diodes 260 of the second module 200C (including the second module 201C and the second module 202C) are blue light emitting diodes 263.

In detail, in the first assembly 100C, the color filter layer 130 is disposed in one of the plurality of first openings 122 of the first light shielding structure 120. For example, the color filter layer 130 includes a red filter layer 132, a green filter layer 134, and a blue filter layer 136. In the embodiment, the color filter layer 130 includes, for example, a color photoresist (photoresist), but not limited thereto.

The light conversion unit 170 includes a first light conversion unit 172 and a second light conversion unit 174. The first light conversion unit 172 is disposed in one of the plurality of second openings 142. The second light conversion unit 174 is disposed in another one of the plurality of second openings 142. In this way, the first light conversion unit 172 and the second light conversion unit 174 can be disposed corresponding to the plurality of blue light emitting diodes 263.

In the present embodiment, the first light conversion unit 172 includes, for example, a red light emitting Quantum Dot (QD) material. The second light conversion unit 174 for example comprises a green emitting quantum dot material. Under the above arrangement, the blue light emitted from the blue led 263 can be converted into red light by the first light conversion unit 172. The red light can be reflected by the first spacer layer 140 to improve the light utilization efficiency. In addition, the red light may penetrate the red filter layer 132 to provide red light of good display quality. Similarly, blue light emitted from the blue light emitting diode 263 may be converted into green light by the second light conversion unit 174. The green light can be reflected by the first spacer layer 140 to improve the light utilization efficiency. In addition, green light may penetrate the green filter layer 134 to provide green light of good display quality.

In the embodiment, the first assembly 100C further includes a scattering layer 150 disposed in one of the second openings 142 and corresponding to the blue filter layer 136. Under the above configuration, the blue light emitted from the blue led 263 can be scattered or diffused by the scattering layer 150, so as to increase the amount of the visible light. The blue light can be reflected by the first spacer layer 140 to improve the light utilization efficiency. In addition, blue light may penetrate the blue filter layer 136 to provide blue light of good display quality. Therefore, the display device 10C can have good display quality or display effect. In addition, the display device 10C can also achieve excellent technical effects similar to those of the above-described embodiment.

Fig. 6 is a schematic cross-sectional view of a display device according to another embodiment of the disclosure. The display device 10D of the present embodiment is substantially similar to the display device 10C of fig. 5, and therefore the same and similar components in the two embodiments are not repeated here. The present embodiment is different from the display device 10C mainly in that the plurality of light emitting diodes of the display device 10D are blue and green. For example, the plurality of leds 260 of the second component 200D (including the second component 201D and the second component 202D) include a green led 262 and a blue led 263.

In the present embodiment, the first assembly 100D includes the first light conversion unit 172 disposed corresponding to the red filter layer 132. The scattering layers 150 are disposed corresponding to the green filter layer 134 and the blue filter layer 136, respectively. One of the plurality of blue leds 263 corresponds to the first light conversion unit 172 and the red filter layer 132. Another of the plurality of blue leds 263 corresponds to the scattering layer 150 and the blue filter layer 136. The green led 262 corresponds to the scattering layer 150 and the green filter layer 134. Under the above configuration, the blue light emitted from the blue led 263 can be converted into red light by the first light conversion unit 172, and then the red light passes through the red filter layer 132 to exit the first device 100D. The filtered light emitted from the green led 262 can be scattered or diffused by the scattering layer 150, and then pass through the green filter layer 134 to exit the first component 100D. The blue light emitted from the blue led 263 can be scattered or diffused by the scattering layer 150, and then passes through the blue filter layer 136 to exit the first component 100D. In this way, the display device 10D can have good display quality or display effect. In addition, the display device 10D can also achieve excellent technical effects similar to those of the above-described embodiment.

Fig. 7 is a schematic cross-sectional view of a display device according to another embodiment of the disclosure. The display device 10E of the present embodiment is substantially similar to the display device 10D of fig. 6, and therefore the same and similar components in the two embodiments are not repeated here. The present embodiment is different from the display device 10D mainly in that the first light shielding structure 120 of the first assembly 100E further has a first see-through opening O1. The second spacer layer 240 of the second assembly 200E (including the second assembly 201E and the second assembly 202E) is gathered with a second see-through opening O2. The second see-through opening O2 corresponds to a portion of the first see-through opening O1. The first perspective opening O1 and the second perspective opening O2 in this embodiment can be used to increase the perspective effect of the transparent display area.

In detail, the first perspective opening O1 of the first component 100E may correspond to a portion of the second opening 142 of the first spacer layer 140. Accordingly, the first assembly 100E may be applied as a cover plate and/or a color substrate of a transparent display device.

The second see-through opening O2 of the second assembly 200E corresponds to a portion of the second opening 142, or corresponds to a portion of the first see-through opening O1. For example, the second perspective opening O2 may correspond to overlap of 20% to 100% of the first perspective opening O1 with a tolerance of ± 10%, such as 20% ± 10%, 40% ± 10%, 60% ± 10%, 80% ± 10% or 100%, but not limited thereto. It should be noted that, according to the design and requirement of the user, the number of the first perspective opening O1 and the second perspective opening O2 can be correspondingly plural, so as to balance the perspective effect, the aperture ratio or the resolution.

Thus, when the user views the first assembly 100E, the user can view the environment behind the second substrate 210 (e.g., glass) through the first perspective opening O1, the second opening 142 and the second perspective opening O2. That is, the display device 10E has a technique applied as a transparent display device. In addition, the display device 10E can also achieve excellent technical effects similar to those of the above-described embodiments.

Fig. 8 is a schematic cross-sectional view of a display device according to another embodiment of the disclosure. The display device 10F of the present embodiment is substantially similar to the display device 10E of fig. 7, and therefore the same and similar components in the two embodiments are not repeated here. The present embodiment is different from the display device 10E mainly in that the first light shielding structure 120 of the first assembly 100F further includes a third opening 124. The third opening 124 corresponds to a gap GP between any two second components 200E (e.g., the second component 201E and the second component 202E).

In detail, the third opening 124 corresponds to a portion of the second opening 142 of the first spacer layer 140. That is, the present embodiment can also be used as one of the plurality of perspective openings of the first assembly 100E for realizing the perspective effect through the third opening 124 in addition to the first perspective opening O1. Thus, when the third opening 124 corresponds to the gap GP, a user can observe the environment behind the second substrate 210 through the third opening 124 and the gap GP. Therefore, the display device 10F has a technique applied as a transparent display device.

In the present embodiment, the width W3 of the third opening 124 and the width of the second opening 142 corresponding to the third opening 124 may be the same or different, and the present embodiment is not limited thereto. In the present embodiment, the width W3 of the third opening 124 is different from the width W5 of the gap GP. For example, the width W3 of the third opening 124 may be smaller than the width W5 of the gap GP. In the present disclosure, the width W3 may be defined as the maximum width of the third opening 124 on the X axis, wherein the exemplary measurement of the width W3 is as the cross-sectional direction in the embodiment, and the distance between two sides of the third opening 124 of the first light shielding structure 120 on the X axis is measured. The width W5 can be defined as the maximum width of the gap GP on the X axis, wherein the exemplary measurement of the width W5 is the distance between two adjacent sides of the second module 201E and the second module 202E on the X axis, as the exemplary cross-sectional direction in this embodiment.

As such, portions of the first light shielding structure 120 may shield portions of the gap GP (also may be referred to as a splice line). Therefore, the splicing line between two adjacent second assemblies 200 is not easy to be observed by the user, and the seamless splicing visual effect can be achieved. In addition, the gap GP and the third opening 124 may also be applied to the technology of a transparent display device. Therefore, the display device 10F can have good display quality or visual effect. In addition, the display device 10F can also achieve excellent technical effects similar to those of the above-described embodiment.

In other embodiments, the width W3 of the third opening 124 may also be greater than or equal to the width W5 of the gap GP. Therefore, the area of the third opening 124 corresponding to the overlapping gap GP can be increased according to the design and requirement of the user. Thus, the display device 10F can have a good see-through effect or aperture ratio.

Fig. 9 is a schematic cross-sectional view of a display device according to another embodiment of the disclosure. The display device 10G of the present embodiment is substantially similar to the display device 10C of fig. 5, and therefore the same and similar components in the two embodiments are not repeated here. The present embodiment is different from the display device 10C in that the first component 100G uses a plurality of stacked color filter layers 130 as the first light shielding structure. For example, the multi-layered color filter layer 130 may include a red filter layer 132, a green filter layer 134, and a blue filter layer 136 partially stacked on one another on the first substrate 110. The first spacer layer 140 has a plurality of second openings 142. Three of the second openings 142 may be disposed corresponding to the red filter layer 132, the green filter layer 134, and the blue filter layer 136, respectively. That is, the three second openings 142 may correspond to three colors, respectively, but the embodiment is not limited thereto.

In the present embodiment, the first light conversion unit 172 is disposed in the plurality of second openings 142 and corresponds to the red filter layer 132. The second light conversion unit 174 is disposed in the plurality of second openings 142 and corresponds to the green color filter layer 134. The scattering layer 150 is disposed in the plurality of second openings 142 and corresponds to the blue filter layer 136. In the present embodiment, the first light conversion unit 172 is, for example, a red light emitting quantum dot material. The second light conversion unit 174 is, for example, a green light emitting quantum dot material. Thus, the display device 10G has good display quality or display effect.

It is noted that the red filter layer 132, the green filter layer 134, and the blue filter layer 136 are partially stacked on the first substrate 110 at a portion of the second opening 142 other than the orthographic projection of the first substrate 110. For example, the stack of the red filter layer 132, the green filter layer 134, and the blue filter layer 136 may correspond to the overlap gap GP. Therefore, since the color filter layers 130 stacked in pairs can correspondingly filter and remove red light, green light, and blue light, the light is absorbed by the color filter layers 130 stacked in pairs and is not easily penetrated. As such, the multi-layered color filter layer 130 can be applied as the first light shielding structure. Therefore, the multi-layer color filter layer 130 can shield the gap GP (also referred to as a stitching line). Therefore, the splicing line between two adjacent second assemblies 200C is not easy to be observed by the user, and the seamless splicing visual effect can be achieved. Therefore, the display device 10G can have good display quality or visual effect. In addition, the display device 10G can also achieve excellent technical effects similar to those of the above-described embodiments.

In summary, the display device of the embodiment of the disclosure includes a first assembly and a plurality of second assemblies, and the plurality of light emitting diodes on the second assemblies are disposed corresponding to the first openings of the first assembly. Since the plurality of second assemblies can be directly spliced on the first assembly, the manufacturing process of the display device can be simplified. The bezel size of the second component can also be reduced. Therefore, the display device can achieve the visual effect of seamless splicing or has good display quality. In addition, the gap between two adjacent second assemblies can be shielded by the first shading structure of the first assembly. As such, the gap and/or the stitching line between two adjacent second components is not easily observable by the user. Therefore, the display device has good display quality or visual effect. In addition, the display device of the present disclosure can further improve the light utilization rate or reduce the light mixing probability through the first spacing layer or the first light shielding structure.

In addition, the display device disclosed by the invention can further comprise a scattering layer and a light conversion unit, so that light with good display quality is provided, and the display device has good display quality or display effect. In addition, the display device of the present disclosure may further include a first perspective opening corresponding to the second perspective opening. Alternatively, a third opening is provided on the first light shielding structure corresponding to the gap. Therefore, the display device has good perspective effect or aperture opening ratio. The display device may also be applied as a transparent display device.

In addition, the display device disclosed by the invention can also apply a plurality of oppositely-overlapped color filter layers as the first shading structure, so that the display device has good display quality or visual effect.
