Description

Technical Field

[0001] The present disclosure relates to a display device, and more particularly, to a display device including a shielding electrode layer configured to improve alignment of light-emitting elements. Background Art

[0002] The importance of display devices has increased with the development of multimedia. Accordingly, various types of display devices such as organic light-emitting diode (OLED) displays and liquid crystal displays (LCDs) are being used.

[0003] A display device is a device that displays an image and includes a display panel, such as an organic light-emitting display panel or a liquid crystal display panel. Among them, the display device may include a light-emitting element as a light-emitting display panel. For example, a light-emitting diode (LED) may include an OLED using an organic material as a fluorescent material, an inorganic light-emitting diode using an inorganic material as a fluorescent material, and the like.

[0004] Compared with an OLED, an inorganic light-emitting diode using an inorganic semiconductor as a fluorescent material has durability even in a high-temperature environment and has high blue light efficiency. In addition, even in a manufacturing process that is pointed out as a limitation of a conventional inorganic light-emitting diode element, a transfer method using a dielectrophoresis (DEP) method has been developed. Accordingly, research has been continuously conducted on inorganic light-emitting diodes having excellent durability and efficiency compared with OLEDs. Summary of the Invention

[0030] Advantageous Effects

[0031] A display device according to an embodiment may include a shielding electrode disposed adjacent to an alignment region of an inorganic light-emitting diode or configured to form a pattern in a non-alignment region. Since the shielding electrode forms a region where no electric field is formed when the inorganic light-emitting diodes are aligned, the inorganic light-emitting diodes may be selectively aligned only in regions where the shielding electrode is not provided.

[0032] Accordingly, in the display device, the inorganic light-emitting diodes may be aligned to have a high alignment in regions where the shielding electrode is not provided. In a display device in which the inorganic light-emitting diodes are aligned to have a high alignment, the emission uniformity of each pixel may be improved, and the loss rate of the inorganic light-emitting diodes may be reduced.

[0054] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. However, the invention may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0055] It will also be understood that when a layer is referred to as being "on" another layer or substrate, the layer can be directly on the other layer or substrate, or an intermediate layer may also be present. Throughout the specification, like reference numerals denote like components.

[0056] It will be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the teachings of the present invention, the first element discussed below may be referred to as the second element. Similarly, the second element may also be referred to as the first element.

[0057] Hereinafter, embodiments will be described with reference to the accompanying drawings.

[0058] Figure 1 is a plan view of a display device according to an embodiment.

[0059] Referring to Figure 1 , the display device 10 may include a plurality of pixels PX. Each pixel PX may include one or more light-emitting elements 300 configured to emit light having a specific wavelength, thereby displaying a specific color.

[0060] Each of the plurality of pixels PX may include a first sub-pixel PX1, a second sub-pixel PX2, and a third sub-pixel PX3. The first sub-pixel PX1 may emit light having a first color, the second sub-pixel PX2 may emit light having a second color, and the third sub-pixel PX3 may emit light having a third color. The first color may be red, the second color may be green, and the third color may be blue, but the present disclosure is not limited thereto. In some cases, the sub-pixel PXn may emit light having the same color. Additionally, although Figure 1 shows each pixel PX including three sub-pixels, the present disclosure is not limited thereto, and each pixel PX may include four or more sub-pixels.

[0061] Each sub-pixel PXn of the display device 10 may include an alignment region AA and a non-alignment region NAA, and the light-emitting element 300 is disposed in the alignment region AA. The alignment region AA may be defined as a region where the shielding electrode layer 800 described below is not provided and the light-emitting element 300 is aligned between the exposed electrodes 210 and 220. The non-alignment region NAA may be defined as a region other than the alignment region AA where the light-emitting element 300 is not aligned.

[0062] In addition, in this specification, a term such as "exposed" or a variant thereof means that the first member and the second member include a region where the first member and the second member do not partially overlap each other in the thickness direction. Even when neither member is exposed to the outside, the term can be interpreted in this way. That is, even when at least one member is disposed between the first member and the second member, there is a region where the first member and the second member do not overlap each other in the thickness direction, which can be interpreted as any one member exposing the other member or being exposed by the other member.

[0063] The display device 10 according to an embodiment may include a shielding electrode layer 800 that exposes at least a part of the electrodes 210 and 220 disposed in each pixel PX or sub-pixel PXn. The shielding electrode layer 800 may be disposed to expose at least a part of the electrodes 210 and 220 and partially overlap with the electrodes 210 and 220. The light-emitting element 300 is aligned in the region where the electrodes 210 and 220 are exposed, and thus, the alignment region AA is formed. In addition, the non-alignment region NAA is formed in a region other than the alignment region AA, and the non-alignment region NAA includes a region on the electrodes 210 and 220 covered by the shielding electrode layer 800.

[0064] In the manufacturing process of the display device 10, a process of forming an electric field between the electrodes 210 and 220 to align the light-emitting element 300 is performed. The electric field may be formed by applying an alignment signal to the electrodes 210 and 220, and the shielding electrode layer 800 may block the electric field formed by the alignment signal. That is, the electric field may not be formed in the region of the electrodes 210 and 220 covered by the shielding electrode layer 800, and the electric field may be formed only in the exposed region of the electrodes 210 and 220 other than the covered region. Therefore, in the manufacturing process of the display device 10, the light-emitting element 300 is selectively aligned in a specific region, thereby improving the alignment of the light-emitting element 300 provided in the display device 10. A more detailed description will be given below.

[0065] The sub-pixel PXn of the display device 10 may include a plurality of bank members, a plurality of electrodes 210 and 220, a plurality of light-emitting elements 300, and a shielding electrode layer 800 that does not overlap with at least a part of the regions on the electrodes 210 and 220.

[0066] A plurality of electrodes 210 and 220 may be electrically connected to the light-emitting element 300 and may receive a predetermined voltage such that the light-emitting element 300 emits light. In addition, in order to align the light-emitting element 300, at least a part of the electrodes 210 and 220 may be used to form an electric field in the sub-pixel PXn.

[0067] Referring to Figure 1 Describing the electrodes 210 and 220 in detail, the plurality of electrodes 210 and 220 may include a first electrode 210 and a second electrode 220. In an embodiment, the first electrode 210 may be a pixel electrode separated for each sub-pixel PXn, and the second electrode 220 may be a common electrode commonly connected along each sub-pixel PXn. One of the first electrode 210 and the second electrode 220 may be an anode of the light-emitting element 300, and the other thereof may be a cathode of the light-emitting element 300. However, the present disclosure is not limited thereto, and the opposite case may also be possible.

[0068] The first electrode 210 and the second electrode 220 may include: electrode main portions 210S and 220S, which are provided to extend in a first direction D1; and one or more electrode branch portions 210B and 220B, which branch from the electrode main portions 210S and 220S, respectively, to extend in a second direction D2, and the second direction D2 is a direction intersecting the first direction D1.

[0069] Specifically, the first electrode 210 may include: a first electrode main portion 210S, which is provided to extend in the first direction D1; and one or more first electrode branch portions 210B, which branch from the first electrode main portion 210S to extend in the second direction D2 (Y-axis direction).

[0070] The first electrode main portion 210S of any pixel may be disposed on substantially the same straight line as the first electrode main portion 210S of an adjacent sub-pixel belonging to the same row (e.g., adjacent thereto in the first direction D1). In other words, both ends of the first electrode main portion 210S of one pixel may be spaced apart from the sub-pixel PXn and terminate between the sub-pixels PXn, and the first electrode main portion 210S of an adjacent pixel may be aligned on the extension line of the first electrode main portion 210S of one pixel. Therefore, the first electrode main portion 210S disposed in each sub-pixel PXn may apply different electrical signals to the first electrode branch portion 210B, and each first electrode branch portion 210B may be individually driven.

[0071] The first electrode branch portion 210B may branch from at least a part of the first electrode main portion 210S, may be provided to extend in the second direction D2, and may terminate in a state of being spaced apart from the second electrode main portion 220S disposed opposite to the first electrode main portion 210S.

[0072] The second electrode 220 may include: a second electrode main body part 220S, which is arranged to extend in the first direction D1 and is spaced apart to face the first electrode main body part 210S; and a second electrode branch part 220B, which branches from the second electrode main body part 220S and is arranged to extend in the second direction D2. However, one end of the second electrode main body part 220S may extend in the first direction D1 to a plurality of adjacent sub-pixels PXn. Therefore, both ends of the second electrode main body part 220S of any pixel may be connected to other ends of the second electrode main body part 220S of adjacent pixels between the pixels PX.

[0073] The second electrode branch part 220B may be arranged to be spaced apart from and face the first electrode branch part 210B, and may terminate in a state spaced apart from the first electrode main body part 210S. That is to say, one end of the second electrode branch part 220B may be connected to the second electrode main body part 220S, while the other end thereof may be arranged in the sub-pixel PXn in a state spaced apart from the first electrode main body part 210S.

[0074] In addition, one or more first electrode branch parts 210B may be arranged in each sub-pixel PXn. Figure 1 It is shown that two first electrode branch parts 210B are arranged and the second electrode branch part 220B is arranged between the two first electrode branch parts 210B, but the present disclosure is not limited thereto. More first electrode branch parts 210B may be arranged, or one first electrode branch part 210B may be arranged and two second electrode branch parts 220B may be arranged. In some embodiments, the second electrode branch part 220B may be arranged between the first electrode branch parts 210B. Therefore, each sub-pixel PXn may have a symmetric structure based on the second electrode branch part 220B. However, the present disclosure is not limited thereto.

[0075] The plurality of dam members may include a third dam member 430 arranged at the boundary between the sub-pixels PXn and a first dam member 410 and a second dam member 420 respectively arranged below the electrodes 210 and 220. In the drawings, only the first electrode 210 and the second electrode 220 are shown, and the first dam member 410 and the second dam member 420 are not shown. However, in each sub-pixel PXn, the first dam member 410 and the second dam member 420 having substantially the same shape as the shapes of the first electrode branch part 210B and the second electrode branch part 220B may be arranged. That is to say, it can be understood that the first electrode branch part 210B and the second electrode branch part 220B are respectively arranged on the first dam member 410 and the second dam member 420.

[0076] The third bank 430 may be disposed at the boundaries between the first sub-pixel PX1 and the second sub-pixel PX2 and between the second sub-pixel PX2 and the third sub-pixel PX3. The ends of the plurality of first electrode main portions 210S may be spaced apart from each other and terminated based on the third bank 430. The third bank 430 may extend in the second direction D2 and may be disposed at the boundaries between the sub-pixels PXn arranged along the first direction D1. However, the present disclosure is not limited thereto, and the third bank 430 may extend in the first direction D1 and may be disposed at the boundaries between the sub-pixels PXn arranged along the second direction D2. That is, the plurality of sub-pixels PXn may be separated based on the third bank 430. The third bank 430 may include the same material as that of the first bank 410 and the second bank 420, and thus may be formed by substantially the same process as the first bank 410 and the second bank 420. The plurality of banks will be described in more detail with reference to other drawings below.

[0077] Although Figure 1 not shown in the figure, the first insulating layer 510 may be disposed in each sub-pixel PXn to completely cover the sub-pixel PXn including the first electrode branch portion 210B and the second electrode branch portion 220B. The first insulating layer 510 may protect each of the electrodes 210 and 220 and at the same time insulate the electrodes 210 and 220 from each other so that the electrodes 210 and 220 do not directly contact each other.

[0078] The shielding electrode layer 800 is disposed on the first insulating layer 510. The shielding electrode layer 800 and the electrodes 210 and 220 may not directly contact each other due to the first insulating layer 510 disposed therebetween. However, as will be described below, the shielding electrode layer 800 and the electrodes 210 and 220 may be electrically connected to each other through the contact electrode 260.

[0079] The shielding electrode layer 800 may include a first shielding electrode 810 disposed on the first electrode 210 and a second shielding electrode 820 disposed on the second electrode 220. The first shielding electrode 810 and the second shielding electrode 820 may be disposed on the electrode main portions 210S and 220S and the electrode branch portions 210B and 220B to cover the electrode main portions 210S and 220S and the electrode branch portions 210B and 220B. That is, the first shielding electrode 810 and the second shielding electrode 820 may also include main portions and branch portions to form a pattern substantially the same as the patterns of the first electrode 210 and the second electrode 220.

[0080] According to one embodiment, the first shielding electrode 810 may include a first shielding electrode main body portion 810S and a first shielding electrode branch portion 810B, and the second shielding electrode 820 may include a second shielding electrode main body portion 820S and a second shielding electrode branch portion 820B.

[0081] The first shielding electrode main body portion 810S and the second shielding electrode main body portion 820S may both extend in the first direction D1 and may be spaced apart from each other in the second direction D2. That is, the first shielding electrode main body portion 810S and the second shielding electrode main body portion 820S may respectively have substantially the same shape as the shapes of the first electrode main body portion 210S and the second electrode main body portion 220S. Specifically, the first shielding electrode main body portion 810S may be spaced apart from the third embankment member 430 and may terminate at the boundary of adjacent sub-pixels PXn, and the second shielding electrode main body portion 820S may extend beyond the adjacent sub-pixels PXn.

[0082] The first shielding electrode branch portion 810B and the second shielding electrode branch portion 820B may branch from the main body to extend in the second direction D2. The first shielding electrode branch portion 810B and the second shielding electrode branch portion 820B may respectively have substantially the same shape as the shapes of the first electrode branch portion 210B and the second electrode branch portion 220B. That is, the first shielding electrode branch portion 810B and the second shielding electrode branch portion 820B may extend in the second direction D2 and may be spaced apart from each other to face each other.

[0083] In addition, according to one embodiment, at least partial regions of the side surfaces of the first shielding electrode 810 and the second shielding electrode 820 may be recessed to form a pattern. The first shielding electrode 810 and the second shielding electrode 820 may include recessed pattern portions 810C and 820C formed by recessing partial regions of their side surfaces, and the electrodes 210 and 220 located in the regions overlapping the recessed pattern portions 810C and 820C may be partially exposed. That is, the recessed pattern portions 810C and 820C may be formed such that the first shielding electrode 810 and the second shielding electrode 820 do not overlap at least partially with the electrodes 210 and 220.

[0084] Specifically, the recessed pattern portions 810C and 820C may be formed in at least one side surface (e.g., the facing side surface) of the first shielding electrode branch portion 810B and the second shielding electrode branch portion 820B. The first recessed pattern portion 810C may be formed in one side surface of the first shielding electrode branch portion 810B facing the second shielding electrode branch portion 820B, so as to recess from the one side surface toward the center of the first shielding electrode branch portion 810B. The second recessed pattern portion 820C may be formed in two side surfaces of the second shielding electrode branch portion 820B facing the first shielding electrode branch portion 810B, so as to recess from the two side surfaces toward the center of the second shielding electrode branch portion 820B.

[0085] The first recessed pattern portion 810C and the second recessed pattern portion 820C are spaced apart from each other to face each other, and the first electrode branch portion 210B and the second electrode branch portion 220B respectively overlapping the first recessed pattern portion 810C and the second recessed pattern portion 820C may be partially exposed. The light-emitting element 300 is aligned in such an exposed area, and two end portions of the light-emitting element 300 may be electrically connected to the first electrode branch portion 210B and the second electrode branch portion 220B. That is, the area formed by the first recessed pattern portion 810C and the second recessed pattern portion 820C spaced apart from each other to face each other may be the alignment area AA.

[0086] On the other hand, in an area where the first recessed pattern portion 810C and the second recessed pattern portion 820C are not formed, the first shielding electrode branch portion 810B and the second shielding electrode branch portion 820B are provided to cover the first electrode branch portion 210B and the second electrode branch portion 220B respectively, and the light-emitting element 300 is not aligned in the area between the first shielding electrode branch portion 810B and the second shielding electrode branch portion 820B and the covered first electrode branch portion 210B and the second electrode branch portion 220B. Therefore, this area may be the non-alignment area NAA.

[0087] However, the structure of the shielding electrode layer 800 is not limited thereto. As will be described below, the structure of the shielding electrode layer 800 is not particularly limited as long as the structure blocks the electric field formed by the alignment signal in the manufacturing process of the display device 10. This will be described in detail below with reference to other embodiments.

[0088] In addition, in the manufacturing process of the display device 10, the shielding electrode layer 800 may be a floating electrode insulated from the electrodes 210 and 220. The alignment signals applied to the electrodes 210 and 220 to align the light-emitting elements 300 may not be transmitted to the shielding electrode layer 800, and the shielding electrode layer 800 may block the electric field formed by the alignment signals. When the electrodes 210 and 220 receiving the alignment signals generate an electric field, the region where the shielding electrode layer 800 is provided may be the region where the electric field is blocked, and outside this region, an electric field may be formed, whereby the light-emitting elements 300 may be aligned therein. That is, as described above, the region where the shielding electrode layer 800 covers the electrodes 210 and 220 may be defined as the non-alignment region NAA, and the region where the electrodes 210 and 220 are exposed may be defined as the alignment region AA.

[0089] The shielding electrode layer 800 according to an embodiment may include a material substantially the same as the materials of the electrodes 210 and 220. In an embodiment, the shielding electrode layer 800 may include at least one selected from aluminum (Al), silver (Ag), copper (Cu), indium tin oxide (ITO), indium zinc oxide (IZO), and indium tin zinc oxide (ITZO), and may be formed as at least one layer.

[0090] In the manufacturing process of the display device 10, the shielding electrode layer 800 may be a floating electrode insulated from the electrodes 210 and 220, and may perform the function of blocking an electric field. On the other hand, in the finally manufactured display device 10, the shielding electrode layer 800 may be electrically connected to the electrodes 210 and 220 through the contact electrode 260 described below. When manufacturing the display device 10, the shielding electrode layer 800 may block the electric field to control the region where the light-emitting elements 300 are aligned, and in the display device 10, the shielding electrode layer 800 may be electrically connected to the electrodes 210 and 220 to receive drive signals.

[0091] A plurality of light-emitting elements 300 may be aligned between the first electrode branch portion 210B and the second electrode branch portion 220B. In at least some of the plurality of light-emitting elements 300, one end thereof may be electrically connected to the first electrode branch portion 210B, and the other end thereof may be electrically connected to the second electrode branch portion 220B.

[0092] The plurality of light-emitting elements 300 may be spaced apart from each other in the second direction D2, and may be aligned substantially parallel to each other. The separation distance between the light-emitting elements 300 is not particularly limited. In some cases, the plurality of light-emitting elements 300 may be arranged adjacent to each other to form a group, and a plurality of other light-emitting elements 300 may form a group while being spaced apart from each other at a predetermined interval, and may be oriented and aligned in one direction and have a non-uniform density.

[0093] According to one embodiment, the light-emitting element 300 may be disposed in a region where the shielding electrode layer 800 does not overlap with the electrodes 210 and 220. Thus, both ends of the light-emitting element 300 may be electrically connected to the electrodes 210 and 220. Specifically, the first electrode 210 and the second electrode 220 may be partially exposed in regions where they respectively overlap with the first recess pattern portion 810C and the second recess pattern portion 820C. As described above, in the exposed regions, an electric field may be formed by the alignment signal, and the light-emitting element 300 may be aligned by the electric field. On the other hand, in regions where the first electrode 210 and the second electrode 220 are not exposed, an electric field may not be formed, and the light-emitting element 300 may not be aligned. Therefore, in the manufacturing process of the display device 10, selective alignment of the light-emitting element 300 may be caused only in a predetermined region, thereby improving the alignment of the display device 10.

[0094] The contact electrode 260 may be disposed on each of the first electrode branch portion 210B and the second electrode branch portion 220B. However, the contact electrode 260 may be substantially disposed on the first insulating layer 510 and may partially overlap with the first electrode branch portion 210B and the second electrode branch portion 220B.

[0095] The plurality of contact electrodes 260 may be disposed in a shape extending in the second direction D2 and may be disposed spaced apart from each other in the first direction D1. The contact electrode 260 may be disposed in a region where the first recess pattern portion 810C and the second recess pattern portion 820C are formed to be spaced apart from each other, and may be disconnected and patterned in a region where the first recess pattern portion 810C and the second recess pattern portion 820C are not provided. That is, as shown in the drawings, the contact electrodes 260 disposed between the first electrode branch portion 210B and the second electrode branch portion 220B may form a pattern arranged in the second direction D2. However, the present disclosure is not limited thereto, and in some cases, the contact electrode 260 may extend in the second direction D2 and may also be formed as one pattern.

[0096] The contact electrode 260 may have a predetermined width and may be disposed on the shielding electrode branch portions 810B and 820B and the electrode branch portions 210B and 220B to partially cover the shielding electrode branch portions 810B and 820B and the electrode branch portions 210B and 220B. The contact electrode 260 may contact at least one end of the light-emitting element 300 and may contact the first electrode 210 or the second electrode 220 to receive an electrical signal. The contact electrode 260 may also contact one side of the shielding electrodes 810 and 820. Thus, the contact electrode 260 may transmit the electrical signal transmitted from the electrodes 210 and 220 to the shielding electrodes 810 and 820 and the light-emitting element 300.

[0097] The contact electrode 260 may include a first contact electrode 261 and a second contact electrode 262, and the first contact electrode 261 and the second contact electrode 262 are in contact with one end or the other end of the light-emitting element 300. The first contact electrode 261 may be disposed on the first electrode branch portion 210B and may be in contact with one end of the light-emitting element 300 such that the one end may be electrically connected to the first electrode 210. The second contact electrode 262 may be disposed on the second electrode branch portion 220B and may be in contact with the other end of the light-emitting element 300 such that the other end may be electrically connected to the second electrode 220.

[0098] As Figure 1 shown, in each sub-pixel PXn, two first electrode branch portions 210B may be provided, and thus, two first contact electrodes 261 may be provided. In addition, one second electrode branch portion 220B may be provided, and thus, two second contact electrodes 262 may be disposed on its two side surfaces. According to an embodiment, the first contact electrode 261 and the second contact electrode 262 may be in contact with one side surface of the first electrode branch portion 210B and the second electrode branch portion 220B, respectively, and may be in contact with one side surface of the first shielding electrode 810 and the second shielding electrode 820, respectively, at the same time.

[0099] Figure 2 and Figure 3 are schematic cross-sectional views showing a display device according to an embodiment. Figure 2 shows a cross-section including both ends of the light-emitting element 300 cut in the first direction D1 Figure 1 in Figure 3 shows a cross-section including the recess pattern portion 810C of the shielding electrode layer 800 cut in the second direction D2 Figure 1 in Figure 2 and Figure 3 schematically shows a cross-section of the display device 10 according to an embodiment, and the structure of the display device 10 is not limited thereto.

[0100] First, referring to Figure 2 , the first electrode 210 and the second electrode 220 are disposed to be spaced apart from each other on the via layer 200 that supports the first electrode 210 and the second electrode 220. The via layer 200 will be described in detail below with reference to Figure 4 . The first insulating layer 510 may be disposed on the first electrode 210 and the second electrode 220 to partially cover the first electrode 210 and the second electrode 220, and the light-emitting element 300 may be disposed on the first insulating layer 510 disposed between the first electrode 210 and the second electrode 220. The first shielding electrode 810 and the second shielding electrode 820 may be disposed on the first insulating layer 510 disposed on the first electrode 210 and the second electrode 220.

[0101] The first shielding electrode 810 and the second shielding electrode 820 are respectively partially overlapped with the first electrode 210 and the second electrode 220, and the regions where the first shielding electrode 810 and the second shielding electrode 820 do not overlap with the first electrode 210 and the second electrode 220 may be the regions where the recessed pattern portions 810C and 820C are provided. The first contact electrode 261 and the second contact electrode 262 may be in contact with the first shielding electrode 810 and the second shielding electrode 820, the light-emitting element 300, the first electrode 210 and the second electrode 220, and the first insulating layer 510. The first contact electrode 261 and the second contact electrode 262 may be in contact with the first electrode 210 and the second electrode 220 in the regions where the recessed pattern portions 810C and 820C are provided.

[0102] According to one embodiment, the first contact electrode 261 may be in contact with one side portion of the first shielding electrode 810, and one second contact electrode 262 may be in contact with one side portion of the second shielding electrode 820. However, the present disclosure is not limited thereto, and in some cases, the first contact electrode 261 may have a relatively wide width and may be in contact with both side portions of the first shielding electrode 810, and one second contact electrode 262 may also be in contact with both side portions of the second shielding electrode 820.

[0103] In addition, the shielding electrode layer 800 may include the recessed pattern portions 810C and 820C, and thus, the separation distance between the first shielding electrode 810 and the second shielding electrode 820 may be different from the separation distance between the first electrode 210 and the second electrode 220. In the display device 10 according to one embodiment, the distance between the shielding electrodes 810 and 820 measured in one direction passing through both ends of the light-emitting element 300 may be greater than the distance between the electrodes 210 and 220 measured in the said one direction.

[0104] Specifically, as Figure 1 and Figure 2 shown, in the alignment region AA where the light-emitting element 300 is provided, the electrode 210 and the shielding electrode 810 may be spaced apart from the electrode 220 and the shielding electrode 820 respectively in a first direction D1 passing through both ends of the light-emitting element 300. The separation distance S1 between the electrodes 210 and 220 measured in the first direction D1 may be smaller than the separation distance S2 between the shielding electrodes 810 and 820 measured in the first direction D1.

[0105] The first shielding electrode 810 and the second shielding electrode 820 respectively form patterns substantially the same as those of the first electrode 210 and the second electrode 220, and due to the formation of the first recessed pattern portion 810C and the second recessed pattern portion 820C, one side surface of the first shielding electrode 810 and the second shielding electrode 820 can be formed to be recessed. Specifically, in the alignment region AA where the recessed pattern portions 810C and 820C are formed, the separation distance S1 between the electrodes 210 and 220 can be smaller than the separation distance S2 between the shielding electrodes 810 and 820.

[0106] Accordingly, one side surface of the electrodes 210 and 220 can be set to protrude from one side surface of the shielding electrodes 810 and 820 (e.g., one side surface facing the light-emitting element 300). The shielding electrodes 810 and 820 may not be provided on the first insulating layer 510 that overlaps with such a protruding region, and the first insulating layer 510 can be exposed in the protruding region. In the manufacturing process of the display device 10, an electric field is formed in the region where the electrodes 210 and 220 protrude and thus the first insulating layer 510 is exposed, so that the light-emitting element 300 can be aligned.

[0107] According to one embodiment, in the alignment region AA, the separation distance S1 between the electrodes 210 and 220 measured in one direction can be smaller than the distance between both ends of the light-emitting element 300 (i.e., the length h ( Figure 6 as shown in)), and the separation distance S2 between the shielding electrodes 810 and 820 can be larger than the length h of the light-emitting element 300 ( Figure 6 as shown in).

[0108] Since the light-emitting element 300 has a length h greater than the separation distance S1 between the first electrode 210 and the second electrode 220, the light-emitting element 300 can be disposed between the first electrode 210 and the second electrode 220 such that both of its ends can be connected to the first electrode 210 and the second electrode 220. Additionally, since the light-emitting element 300 has a length h ( Figure 6 as shown in) smaller than the separation distance S2 between the first shielding electrode 810 and the second shielding electrode 820, the light-emitting element 300 can be aligned to be spaced apart from the shielding electrodes 810 and 820 on the electrodes 210 and 220 and not to overlap with the shielding electrodes 810 and 820.

[0109] However, the present disclosure is not limited thereto, and in the region where the recessed pattern portions 810C and 820C of the shielding electrodes 810 and 820 are not formed, the separation distance between the shielding electrodes 810 and 820 can be smaller than or equal to the separation distance between the electrodes 210 and 220.

[0110] Refer to Figure 3, in a cross-section of a region in which a first electrode 210 and a first shielding electrode 810 are provided, in a second direction D2, the first shielding electrode 810 may form a pattern arranged in the second direction D2, and a plurality of light-emitting elements 300 may be provided between the first shielding electrodes 810 spaced apart from each other. The region in which the first shielding electrode 810 is provided may be understood as a region in which an electric field is not formed during the manufacturing process of the display device 10, and the region in which the first shielding electrodes 810 are spaced apart from each other (i.e., the region in which the first recessed pattern portion 810C is formed) may be understood as a region in which an electric field is formed. Since the first shielding electrode 810 is formed, the light-emitting elements 300 can be aligned only in the region in which the first recessed pattern portion 810C is provided, and the number of light-emitting elements 300 aligned at unnecessary positions can be reduced.

[0111] In addition, a first electrode main body portion 210S and a second electrode main body portion 220S may be electrically connected to a first transistor 120 or a power line 161 to be described below through contact holes (e.g., a first electrode contact hole CNTD and a second electrode contact hole CNTS), respectively. In the drawings, one second electrode contact hole CNTS is shown as being formed in the second electrode main body portion 220S of a plurality of sub-pixels PXn. However, the present disclosure is not limited thereto, and in some cases, a second electrode contact hole CNTS may be formed for each sub-pixel PXn.

[0112] In addition, although Figure 1 not shown, the display device 10 may include a second insulating layer 520 ( Figure 4 shown in Figure 4 ) and a passivation layer 550 ( Figure 4 shown in

[0113] ) that are provided to cover each of the electrodes 210 and 220 and at least a part of the light-emitting element 300. The arrangement and structure therebetween will be described below with reference to Figure 4 .

[0113] The display device 10 may further include a circuit element layer located under each of the electrodes 210 and 220 shown in Figure 1 . Hereinafter, this will be described in detail with reference to other drawings.

[0114] Figure 4 is a cross-sectional view taken along lines Ia-Ia', IIa-IIa', and IIIa-IIIa' of Figure 1 . Figure 5 is a cross-sectional view taken along line IIb-IIb' of Figure 1 . Figure 4 and Figure 5 only show the first sub-pixel PX1 and the second sub-pixel PX2, but this can also be applied to other pixels PX or sub-pixels PXn. Figure 4Shows a cross-section through one end and the other end of any light-emitting element 300.

[0115] Referring Figure 1 and Figure 4 FIGS. and, the display device 10 may include a substrate 110, a buffer layer 115, a first bridging pattern 181 and a second bridging pattern 182, a first transistor 120 and a second transistor 140, electrodes 210 and 220 disposed on the first transistor 120 and the second transistor 140, and a light-emitting element 300.

[0116] Specifically, the substrate 110 may be an insulating substrate. The substrate 110 may be made of an insulating material such as glass, quartz, or a polymer resin. In addition, the substrate 110 may be a rigid substrate or a flexible substrate that can be bent, folded, or rolled.

[0117] The first bridging pattern 181 and the second bridging pattern 182 may be disposed on the substrate 110. The first bridging pattern 181 may be electrically connected to a first drain electrode 123 of the first transistor 120 to be described below. The second bridging pattern 182 may be electrically connected to a second drain electrode 143 of the second transistor 140.

[0118] The first bridging pattern 181 and the second bridging pattern 182 are disposed to overlap with a first active material layer 126 of the first transistor 120 and a second active material layer 146 of the second transistor 140, respectively. The first bridging pattern 181 and the second bridging pattern 182 may include a light-blocking material to prevent light from incident on the first active material layer 126 and the second active material layer 146. As an example, the first bridging pattern 181 and the second bridging pattern 182 may be made of an opaque metal material that blocks light transmission.

[0119] The buffer layer 115 is disposed on the first bridging pattern 181 and the second bridging pattern 182 and the substrate 110. The buffer layer 115 may be disposed to completely cover the substrate 110 and surround the first bridging pattern 181 and the second bridging pattern 182. The buffer layer 115 may prevent the diffusion of impurity ions, prevent the penetration of moisture or ambient air, and perform a surface flattening function. In addition, the buffer layer 115 may insulate the first bridging pattern 181 and the second bridging pattern 182 from the first active material layer 126 and the second active material layer 146.

[0120] A semiconductor layer is disposed on the buffer layer 115. The semiconductor layer may include a first active material layer 126 of the first transistor 120, a second active material layer 146 of the second transistor 140, and an auxiliary material layer 163. The semiconductor layer may include polysilicon, single-crystalline silicon, an oxide semiconductor, etc.

[0121] The first gate insulating film 170 is disposed on the semiconductor layer. The first gate insulating film 170 may be configured to completely cover the buffer layer 115 and surround the semiconductor layer. The first gate insulating film 170 may serve as the gate insulating film for the first transistor 120 and the second transistor 140.

[0122] The first conductive layer is disposed on the first gate insulating film 170. On the first gate insulating film 170, the first conductive layer may include: a first gate electrode 121 disposed on the first active material layer 126 of the first transistor 120; a second gate electrode 141 disposed on the second active material layer 146 of the second transistor 140; and a power line 161 disposed on the auxiliary material layer 163.

[0123] The interlayer insulating film 190 is disposed on the first conductive layer. The interlayer insulating film 190 may perform the function of an interlayer insulating film. Additionally, the interlayer insulating film 190 may include an organic insulating material and may perform a surface planarization function.

[0124] The second conductive layer is disposed on the interlayer insulating film 190. The second conductive layer includes a first drain electrode 123 and a first source electrode 124 of the first transistor 120, a second drain electrode 143 and a second source electrode 144 of the second transistor 140, and a power electrode 162 disposed on the power line 161.

[0125] The first drain electrode 123 and the first source electrode 124 may be electrically connected to the first active material layer 126 through contact holes passing through the interlayer insulating film 190 and the first gate insulating film 170. The second drain electrode 143 and the second source electrode 144 may be electrically connected to the second active material layer 146 through contact holes passing through the interlayer insulating film 190 and the first gate insulating film 170. Additionally, the first drain electrode 123 and the second drain electrode 143 may be electrically connected to the first bridging pattern 181 and the second bridging pattern 182, respectively, through other contact holes.

[0126] The via layer 200 is disposed on the second conductive layer. The via layer 200 may include an organic insulating material to perform a surface planarization function.

[0127] A plurality of dikes 410, 420, and 430 are disposed on the via layer 200. The plurality of dikes 410, 420, and 430 may be disposed to be spaced apart from each other in each sub-pixel PXn. The plurality of dikes 410, 420, and 430 may include a first dike 410 and a second dike 420 disposed adjacent to the central portion of the sub-pixel PXn and a third dike 430 at the boundary between the sub-pixels PXn.

[0128] The third bank 430 may be a bank that distinguishes the boundaries of each sub-pixel PXn. When manufacturing the display device 10, when an organic material or a solvent is sprayed using an inkjet printing method, the third bank 430 may function to block the organic material or the solvent from passing through the boundaries of the sub-pixels PXn. Optionally, when the display device 10 further includes other components, the component may be disposed on the third bank 430, and the third bank 430 may also function to support the component. However, the present disclosure is not limited thereto.

[0129] The first bank 410 and the second bank 420 are disposed to be spaced apart from each other and face each other. The first electrode 210 may be disposed on the first bank 410, and the second electrode 220 may be disposed on the second bank 420. Referring to Figure 1 and Figure 4 , it can be understood that the first electrode branch 210B is disposed on the first bank 410, and the second electrode branch 220B is disposed on the second bank 420. That is, based on Figure 1 , the first bank 410 and the second bank 420 may extend in the second direction D2 and may be disposed to be spaced apart from each other in the first direction D1.

[0130] Figure 4 One first bank 410, one second bank 420, and one third bank 430 are shown, but the present disclosure is not limited thereto. When two first electrode branches 210B are disposed in one sub-pixel PXn as shown in Figure 1 , two first banks 410 and one second bank 420 may be disposed, and each sub-pixel PXn may include more banks 410, 420, and 430.

[0131] As described above, the first bank 410, the second bank 420, and the third bank 430 may be formed by substantially the same process. Therefore, the banks 410, 420, and 430 may form a grid pattern. The plurality of banks 410, 420, and 430 may include polyimide (PI).

[0132] The plurality of banks 410, 420, and 430 may have a structure in which at least a part thereof protrudes from the via layer 200. The banks 410, 420, and 430 may protrude upward from the flat surface on which the light-emitting element 300 is disposed, and at least a part of such protrusions may have an inclination. The shape of the banks 410, 420, and 430 having the protruding structure is not particularly limited. As shown in the drawings, the first bank 410 and the second bank 420 may protrude to the same height, and the third bank 430 may have a shape that protrudes to a higher position.

[0133] The reflective layers 211 and 221 may be disposed on the first dam-like member 410 and the second dam-like member 420, and the electrode layers 212 and 222 may be disposed on the reflective layers 211 and 221. The reflective layers 211 and 221 and the electrode layers 212 and 222 may constitute the electrodes 210 and 220.

[0134] The reflective layers 211 and 221 include a first reflective layer 211 and a second reflective layer 221. The first reflective layer 211 covers the first dam-like member 410, and a part of the first reflective layer 211 is electrically connected to the first drain electrode 123 through a contact hole passing through the via layer 200. The second reflective layer 221 covers the second dam-like member 420, and a part of the second reflective layer 221 is electrically connected to the power electrode 162 through a contact hole passing through the via layer 200. The contact hole through which the first reflective layer 211 is connected may be Figure 1 the first electrode contact hole CNTD, and the contact hole through which the second reflective layer 221 is connected may be Figure 1 the second electrode contact hole CNTS.

[0135] The reflective layers 211 and 221 may include a material having a high reflectivity to reflect the emitted light emitted from the light-emitting element 300. As an example, the reflective layers 211 and 221 may include materials such as silver (Ag), copper (Cu), ITO, IZO, or ITZO, but the present disclosure is not limited thereto.

[0136] The electrode layers 212 and 222 include a first electrode layer 212 and a second electrode layer 222. The electrode layers 212 and 222 may have substantially the same pattern as the reflective layers 211 and 221. The first reflective layer 211 and the first electrode layer 212 are disposed to be spaced apart from the second reflective layer 221 and the second electrode layer 222.

[0137] The electrode layers 212 and 222 may include a transparent conductive material such that the emitted light emitted from the light-emitting element 300 can be incident on the reflective layers 211 and 221. As an example, the electrode layers 212 and 222 may include materials such as ITO, IZO, or ITZO, but the present disclosure is not limited thereto.

[0138] In some embodiments, the reflective layers 211 and 221 and the electrode layers 212 and 222 may have a structure in which at least one transparent conductive layer made of ITO, IZO, or ITZO and at least one metal layer made of silver or copper are stacked. As an example, the reflective layers 211 and 221 and the electrode layers 212 and 222 may have a stacked structure of ITO / Ag / ITO / IZO.

[0139] The first reflective layer 211 and the first electrode layer 212 may form the first electrode 210, and the second reflective layer 221 and the second electrode layer 222 may form the second electrode 220. The first electrode 210 transmits the electrical signal transmitted from the first transistor 120 to the light-emitting element 300 through the first electrode layer 212, and the second electrode 220 transmits the electrical signal transmitted from the power electrode 162 to the light-emitting element 300 through the second electrode layer 222.

[0140] In addition, in some embodiments, the first electrode 210 and the second electrode 220 may be formed as one layer. That is, the reflective layers 211 and 221 and the electrode layers 212 and 222 are formed as a single layer to transmit an electrical signal to the light-emitting element 300 and simultaneously reflect the emitted light. In an embodiment, the first electrode 210 and the second electrode 220 may include a conductive material having a high reflectivity. As an example, the first electrode 210 and the second electrode 220 may be made of an alloy including aluminum (Al), nickel (Ni), lanthanum (La), etc. However, the present disclosure is not limited thereto.

[0141] The first insulating layer 510 is disposed on the first electrode 210 and the second electrode 220 to partially cover the first electrode 210 and the second electrode 220. The first insulating layer 510 may be disposed to cover most of the upper surfaces of the first electrode 210 and the second electrode 220, and may expose portions of the first electrode 210 and the second electrode 220. The first insulating layer 510 may be disposed to cover the separation space between the first electrode 210 and the second electrode 220, and also partially cover the region opposite to the separation space between the first electrode 210 and the second electrode 220.

[0142] The first insulating layer 510 is disposed such that the relatively flat upper surfaces of the first electrode 210 and the second electrode 220 are exposed, and the electrodes 210 and 220 may be disposed to overlap with the inclined side surfaces of the first dam member 410 and the second dam member 420. The first insulating layer 510 has a flat upper surface formed such that the light-emitting element 300 is disposed thereon, and the upper surface extends in one direction toward each of the first electrode 210 and the second electrode 220. This extended portion of the first insulating layer 510 terminates at the inclined side surfaces of the first electrode 210 and the second electrode 220. Therefore, the contact electrode 260 to be described below can contact the exposed first electrode 210 and second electrode 220, and can smoothly contact the light-emitting element 300 on the flat upper surface of the first insulating layer 510.

[0143] The first insulating layer 510 can protect the first electrode 210 and the second electrode 220, and at the same time insulate the first electrode 210 and the second electrode 220 from each other. The first insulating layer 510 can also prevent the light-emitting element 300 disposed on the first insulating layer 510 from being damaged due to direct contact with other components. In addition, in the manufacturing process of the display device 10, the first insulating layer 510 can perform the function of insulating the first electrode 210 and the second electrode 220 from the shielding electrode layer 800. As described above, since the shielding electrode layer 800 is insulated from the electrodes 210 and 220, an electric field may not be formed due to the alignment signal in the region where the shielding electrode layer 800 overlaps with the electrodes 210 and 220. The first insulating layer 510 can be disposed between the shielding electrode layer 800 and the electrodes 210 and 220 to insulate the shielding electrode layer 800 from the electrodes 210 and 220.

[0144] The light-emitting element 300 or the shielding electrode layer 800 is disposed on the first insulating layer 510.

[0145] One or more light-emitting elements 300 can be disposed on the first insulating layer 510 between the first electrode 210 and the second electrode 220. In the light-emitting element 300, a plurality of layers can be disposed in the horizontal direction on the via layer 200. As will be described below, the light-emitting element 300 can include a first conductive type semiconductor 310, an active layer 330, a second conductive type semiconductor 320, and an electrode material layer 370. In the light-emitting element 300 according to one embodiment, a plurality of layers can be sequentially disposed in the horizontal direction on the via layer 200. However, the present disclosure is not limited thereto, and the order of the plurality of layers of the light-emitting element 300 can be reversed. In addition, in some cases, when the light-emitting element 300 has another structure, a plurality of layers can be disposed in a direction perpendicular to the via layer 200. This will be described below with reference to other drawings.

[0146] The shielding electrode layer 800 can be disposed to partially overlap the first insulating layer 510 disposed on the first electrode 210 and the second electrode 220. As Figure 4 shown, the shielding electrode layer 800 can be disposed on the upper surfaces of the first electrode 210 and the second electrode 220, and can extend along the first insulating layer 510 in a direction opposite to the light-emitting element 300. Here, the region where the electrodes 210 and 220 are exposed between the shielding electrode layer 800 and the light-emitting element 300 can be the region where the above-described concave pattern portions 810C and 820C are provided.

[0147] The first shielding electrode 810 may be disposed on the first electrode 210, and the second shielding electrode 820 may be disposed on the second electrode 220. The space between the facing side portions of the first shielding electrode 810 and the second shielding electrode 820 (the region where the light-emitting element 300 is disposed) may be the region where the first recessed pattern portion 810C and the second recessed pattern portion 820C are disposed.

[0148] In the manufacturing process of the display device 10, in the region where the first recessed pattern portion 810C and the second recessed pattern portion 820C are disposed, the first electrode 210 and the second electrode 220 are exposed, and thus, an electric field can be formed. On the other hand, as Figure 5 shown, no electric field is formed in the region where the first electrode 210 and the second electrode 220 overlap with the shielding electrode layer 800.

[0149] Figure 4 is a cross-sectional view including the alignment region AA where the recessed pattern portions 810C and 820C are disposed, Figure 5 is a cross-sectional view including the non-alignment region NAA where the recessed pattern portions 810C and 820C are not disposed.

[0150] Referring to Figure 5 , the first insulating layer 510 may be disposed to cover the entire regions of the first electrode 210 and the second electrode 220, the first shielding electrode 810 may be disposed to cover the first electrode 210, and the second shielding electrode 820 may be disposed to cover the second electrode 220. That is, the first shielding electrode 810 and the second shielding electrode 820 may be partially disposed in the region between the first electrode 210 and the second electrode 220. Since Figure 5 the first shielding electrode 810 and the second shielding electrode 820 are disposed to completely cover the first electrode 210 and the second electrode 220, no electric field can be formed between the first electrode 210 and the second electrode 220 in the manufacturing process of the display device 10. Even when an alignment signal is applied to the first electrode 210 and the second electrode 220, the formation of the electric field can be blocked by the first shielding electrode 810 and the second shielding electrode 820 insulated by the first insulating layer 510. The shielding electrode layer 800 can guide the light-emitting element 300 to be aligned only in the region where the recessed pattern portions 810C and 820C are formed. When the light-emitting element 300 is aligned only in a specific region, the misalignment of the light-emitting element 300 occurring in the manufacturing process of the display device 10 can be minimized or the number of light-emitting elements 300 aligned in an unnecessary region can be minimized. Therefore, in the display device 10 including the shielding electrode layer 800, the alignment of the light-emitting element 300 can be improved.

[0151] In addition, the arrangement or structure of the shielding electrode layer 800 is not limited to Figure 1 ,Figure 4 and Figure 5 the structure shown in Figure 5 . In some cases, the shielding electrode layer 800 may be patterned not to be disposed in the alignment region AA of the light-emitting element 300. For a detailed description thereof, refer to other embodiments.

[0152] Referring again to Figure 4 , the second insulating layer 520 may be disposed on the light-emitting element 300. The second insulating layer 520 may perform both the functions of protecting and fixing the light-emitting element 300. The second insulating layer 520 may be disposed to surround the outer surface of the light-emitting element 300. That is, a part of the material of the second insulating layer 520 may be disposed between the lower surface of the light-emitting element 300 and the first insulating layer 510. The second insulating layer 520 may extend in the second direction D2 between the first electrode branch portion 210B and the second electrode branch portion 220B to have an island shape or a linear shape in a plan view.

[0153] The second insulating layer 520 is disposed to expose both side surfaces of the light-emitting element 300. Accordingly, the contact electrode 260 may be in smooth contact with the side surfaces of both ends of the light-emitting element 300. However, the present disclosure is not limited thereto, and the second insulating layer 520 may be aligned with both ends of the light-emitting element 300.

[0154] The contact electrode 260 is disposed on each of the electrodes 210 and 220, the second insulating layer 520, and the shielding electrode layer 800. The contact electrode 260 includes: a first contact electrode 261 disposed on the first electrode 210 and the first shielding electrode 810; and a second contact electrode 262 disposed on the second electrode 220 and the second shielding electrode 820. The first contact electrode 261 and the second contact electrode 262 are disposed to be spaced apart from each other on the second insulating layer 520. Accordingly, the second insulating layer 520 may insulate the first contact electrode 261 and the second contact electrode 262 from each other.

[0155] The first contact electrode 261 may be in contact with the first shielding electrode 810, the first electrode 210 exposed by patterning the first insulating layer 510, the first insulating layer 510, the light-emitting element 300, and the second insulating layer 520. The second contact electrode 262 may be in contact with the second shielding electrode 820, the second electrode 220 exposed by patterning the first insulating layer 510, the first insulating layer 510, the light-emitting element 300, and the second insulating layer 520. The first contact electrode 261 and the second contact electrode 262 may be in contact with the side surfaces of both ends (e.g., the first conductive type semiconductor 310 and the second conductive type semiconductor 320 or the electrode material layer 370) of the light-emitting element 300, respectively. As described above, the first insulating layer 510 may be formed to have a flat upper surface so that the contact electrode 260 may be in smooth contact with the side surface of the light-emitting element 300.

[0156] In addition, in the manufacturing process of the display device 10, the first shielding electrode 810 and the second shielding electrode 820 set in a floating state may be in contact with the first contact electrode 261 and the second contact electrode 262, respectively. Therefore, the signals applied from the first electrode 210 and the second electrode 220 can be transmitted. However, the present disclosure is not limited thereto, and the shielding electrode layer 800 may remain in a floating state in the display device 10 depending on its arrangement.

[0157] The contact electrode 260 may include a conductive material. For example, the contact electrode 260 may include ITO, IZO, ITZO, aluminum (Al), etc. However, the present disclosure is not limited thereto.

[0158] The passivation layer 550 may be formed on the shielding electrode layer 800, the second insulating layer 520, and the contact electrode 260, and may be used to protect the components provided on the via layer 200 from the external environment.

[0159] Each of the first insulating layer 510, the second insulating layer 520, and the passivation layer 550 may include an inorganic insulating material or an organic insulating material. In an embodiment, the first insulating layer 510 and the passivation layer 550 may include materials such as silicon oxide (SiO x ), silicon nitride (SiN x ), silicon oxynitride (SiO x N y ), aluminum oxide (Al2O3), or aluminum nitride (AlN). The second insulating layer 520 may include a photoresist or the like as an organic insulating material. However, the present disclosure is not limited thereto.

[0160] In addition, the light-emitting element 300 may include a semiconductor crystal doped with impurities of any conductive type (e.g., p-type or n-type). The semiconductor crystal may receive an electrical signal applied from an external power source and emit light having a specific wavelength in response to the received electrical signal.

[0161] The light-emitting element 300 may be a light-emitting diode, and specifically, the light-emitting element 300 may be an inorganic light-emitting diode having a size in the micron or nanometer unit and made of an inorganic material. When the light-emitting element 300 is an inorganic light-emitting diode, and when an electric field is formed in a specific direction between two facing electrodes, the inorganic light-emitting diode may be aligned between the two electrodes where a polarity is formed therebetween. Therefore, by forming an electric field, the light-emitting element 300 having a micro size can be aligned on the electrodes of the display device 10. The light-emitting element 300 may receive a predetermined electrical signal from the electrodes to emit light having a specific wavelength.

[0162] Figure 6 is a schematic diagram of a light-emitting element according to an embodiment.

[0163] Reference Figure 6 According to one embodiment, the light-emitting element 300 may include a plurality of conductive-type semiconductors 310 and 320, an active layer 330, an electrode material layer 370, and an insulating film 380. The plurality of conductive-type semiconductors 310 and 320 may transmit an electrical signal transmitted to the light-emitting element 300 to the active layer 330, and the active layer 330 may emit light having a specific wavelength.

[0164] Specifically, the light-emitting element 300 may include a first conductive-type semiconductor 310, a second conductive-type semiconductor 320, an active layer 330 disposed between the first conductive-type semiconductor 310 and the second conductive-type semiconductor 320, an electrode material layer 370 disposed on the second conductive-type semiconductor 320, and an insulating film 380 disposed to surround the outer surfaces of the first conductive-type semiconductor 310 and the second conductive-type semiconductor 320, the active layer 330, and the electrode material layer 370. In Figure 6 FIG., the light-emitting element 300 is shown as having a structure in which the first conductive-type semiconductor 310, the active layer 330, the second conductive-type semiconductor 320, and the electrode material layer 370 are sequentially formed in its longitudinal direction, but the present disclosure is not limited thereto. The electrode material layer 370 may be omitted, and in some embodiments, the electrode material layer 370 may also be disposed on at least one of the two side surfaces of the first conductive-type semiconductor 310 and the second conductive-type semiconductor 320. Even when the light-emitting element 300 further includes another structure, the same description may be applied to the light-emitting element 300 to be described below.

[0165] The first conductive-type semiconductor 310 may be an n-type semiconductor layer. As an example, when the light-emitting element 300 emits light having a blue wavelength, the first conductive-type semiconductor 310 may be made of a semiconductor material having the chemical formula In x Al y Ga 1-x-y N (0 ≤ x ≤ 1, 0 ≤ y ≤ 1, and 0 ≤ x + y ≤ 1). For example, the first conductive-type semiconductor 310 may be made of at least one selected from n-type doped InAlGaN, GaN, AlGaN, InGaN, AlN, and InN. The first conductive-type semiconductor 310 may be doped with a first conductive-type dopant. As an example, the first conductive-type dopant may be silicon (Si), germanium (Ge), tin (Sn), etc. The first conductive-type semiconductor 310 may have a length in the range of 1.5 μm to 5 μm, but the present disclosure is not limited thereto.

[0166] The second conductive-type semiconductor 320 may be a p-type semiconductor layer. As an example, when the light-emitting element 300 emits light having a blue wavelength, the second conductive-type semiconductor 320 may be made of a semiconductor material having the chemical formula In x Al y Ga1-x-y made of a semiconductor material of N(0≤x≤1, 0≤y≤1, and 0≤x + y≤1). For example, the second-conductivity-type semiconductor 320 can be made of at least one selected from p-type doped InAlGaN, GaN, AlGaN, InGaN, AlN, and InN. The second-conductivity-type semiconductor 320 can be doped with a second-conductivity-type dopant. As an example, the second-conductivity-type dopant can be magnesium (Mg), zinc (Zn), calcium (Ca), selenium (Se), barium (Ba), etc. The second-conductivity-type semiconductor 320 can have a length in the range of 0.08 μm to 0.25 μm, but the present disclosure is not limited thereto.

[0167] In addition, in the drawings, each of the first-conductivity-type semiconductor 310 and the second-conductivity-type semiconductor 320 is shown as being composed of one layer, but the present disclosure is not limited thereto. In some cases, depending on the material of the active layer 330 to be described below, the first-conductivity-type semiconductor 310 and the second-conductivity-type semiconductor 320 can include more layers.

[0168] The active layer 330 can be disposed between the first-conductivity-type semiconductor 310 and the second-conductivity-type semiconductor 320, and can include a material having a single quantum well structure or a multi-quantum well structure. When the active layer 330 includes a material having a multi-quantum well structure, the active layer 330 can have a structure in which a plurality of quantum layers and a plurality of well layers are alternately stacked. According to the electrical signal applied through the first-conductivity-type semiconductor 310 and the second-conductivity-type semiconductor 320, the active layer 330 can emit light due to electron-hole pair recombination. As an example, when the active layer 330 emits light having a blue wavelength, the active layer 330 can include a material such as AlGaN or AlInGaN. Specifically, when the active layer 330 has a structure in which quantum layers and well layers are alternately stacked in a multi-quantum well structure, the quantum layers can include a material such as AlGaN or AlInGaN, and the well layers can include a material such as GaN or AlGaN.

[0169] However, the present disclosure is not limited thereto, and the active layer 330 can have a structure in which a semiconductor material having a high bandgap energy and a semiconductor material having a low bandgap energy are alternately stacked, or can include other group III or V semiconductor materials according to the wavelength of the emitted light. Therefore, the light emitted by the active layer 330 is not limited to light having a blue wavelength, and in some cases, the active layer 330 can emit light having a red wavelength or a green wavelength. The active layer 330 can have a length in the range of 0.05 μm to 0.25 μm, but the present disclosure is not limited thereto.

[0170] In addition, the light emitted from the active layer 330 can be emitted not only to the outer surface of the light-emitting element 300 along its length direction, but also to the two side surfaces of the light-emitting element 300. The directivity of the light emitted from the active layer 330 is not limited to one direction.

[0171] The electrode material layer 370 can be an ohmic contact electrode. However, the present disclosure is not limited thereto, and the electrode material layer 370 can be a Schottky contact electrode. The electrode material layer 370 can include a conductive metal. For example, the electrode material layer 370 can include at least one selected from aluminum (Al), titanium (Ti), indium (In), gold (Au), silver (Ag), ITO, IZO, and ITZO. The electrode material layer 370 can include the same material or different materials, but the present disclosure is not limited thereto.

[0172] The insulating film 380 can be formed to contact and surround the outer surfaces of the first conductive type semiconductor 310, the second conductive type semiconductor 320, the active layer 330, and the electrode material layer 370. The insulating film 380 can perform the function of protecting these components. As an example, the insulating film 380 can be formed to surround the side surfaces of the components, and can be formed to expose the two ends of the light-emitting element 300 in its length direction. However, the present disclosure is not limited thereto.

[0173] The insulating film 380 can include at least one selected from materials having insulating properties (e.g., silicon oxide (SiO x ), silicon nitride (SiN x ), silicon oxynitride (SiO x N y ), aluminum nitride (AlN), and aluminum oxide (Al2O3)). Therefore, it is possible to prevent an electrical short circuit that may occur when the active layer 330 is in direct contact with the electrode through which an electrical signal is transmitted to the light-emitting element 300. In addition, since the insulating film 380 protects the outer surface of the light-emitting element 300 including the active layer 330, it is possible to prevent a reduction in luminous efficiency.

[0174] In the drawings, the insulating film 380 is shown as being formed to extend in the length direction of the light-emitting element 300 and cover the first conductive type semiconductor 310 to the electrode material layer 370, but the present disclosure is not limited thereto. The insulating film 380 can only cover the first conductive type semiconductor 310, the active layer 330, and the second conductive type semiconductor 320, or can cover a part of the outer surface of the electrode material layer 370 such that a part of the outer surface of the electrode material layer 370 can be exposed.

[0175] The insulating film 380 can have a thickness in the range of 0.5 μm to 1.5 μm, but the present disclosure is not limited thereto.

[0176] In addition, in some embodiments, the outer surface of the insulating film 380 may be surface-treated. When manufacturing the display device 10, the light-emitting elements 300 may be aligned by being sprayed on the electrodes in a state of being dispersed in a predetermined ink. Here, in order to keep the light-emitting elements 300 dispersed and not agglomerated with other adjacent light-emitting elements 300 in the ink, the surface of the insulating film 380 may be subjected to hydrophobic or hydrophilic treatment.

[0177] The light-emitting element 300 may have a shape extending in one direction. The light-emitting element 300 may have a shape such as a nanorod, a nanowire, or a nanotube. In an embodiment, the light-emitting element 300 may have a cylindrical shape or a rod shape. However, the shape of the light-emitting element 300 is not limited thereto, and the light-emitting element 300 may have various shapes such as a hexahedron, a rectangular parallelepiped, and a hexagonal prism.

[0178] Figure 7 is a schematic diagram of a light-emitting element according to another embodiment.

[0179] Referring to Figure 7 , the multiple layers of the light-emitting element 300' may not be stacked in one direction, and each layer may be formed to surround the outer surface of another layer. Except that Figure 7 the shape of each layer of the light-emitting element 300' is partially different from the shape of each layer of the light-emitting element 300, Figure 7 the light-emitting element 300' of Figure 6 is the same as the light-emitting element 300 of

[0180] According to one embodiment, the first-conductive-type semiconductor 310' may extend in one direction, and its two end portions may be formed to be inclined toward its center. Figure 7 The first-conductive-type semiconductor 310' of

[0181] The active layer 330' is disposed to surround the outer surface of the main body portion of the first-conductive-type semiconductor 310'. The active layer 330' may have an annular shape extending in one direction. The active layer 330' is not formed on the upper end portion and the lower end portion of the first-conductive-type semiconductor 310'. That is, the active layer 330' may only be in contact with the parallel side surfaces of the first-conductive-type semiconductor 310'.

[0182] The second-conductivity-type semiconductor 320' is disposed to surround the outer surface of the active layer 330' and the upper end portion of the first-conductivity-type semiconductor 310'. The second-conductivity-type semiconductor 320' may include a main body portion having an annular shape extending in one direction and an upper end portion formed to have an inclined side surface. That is, the second-conductivity-type semiconductor 320' may be in direct contact with the side surface parallel to the active layer 330' and the inclined upper end portion of the first-conductivity-type semiconductor 310'. However, the second-conductivity-type semiconductor 320' is not formed on the lower end portion of the first-conductivity-type semiconductor 310'.

[0183] The electrode material layer 370' is disposed to surround the outer surface of the second-conductivity-type semiconductor 320'. That is, the electrode material layer 370' may have a shape substantially the same as the shape of the second-conductivity-type semiconductor 320'. That is, the electrode material layer 370' may be in contact with the entire outer surface of the second-conductivity-type semiconductor 320'.

[0184] The insulating film 380' may be disposed to surround the outer surfaces of the electrode material layer 370' and the first-conductivity-type semiconductor 310'. The insulating film 380' may be in direct contact with the lower end portion of the first-conductivity-type semiconductor 310' and the exposed lower ends of the active layer 330' and the second-conductivity-type semiconductor 320' and surround the electrode material layer 370'.

[0185] In addition, Figure 7 the light-emitting element 300' may be disposed such that one direction along which the first-conductivity-type semiconductor 310' extends is parallel to the direction horizontal to the via layer 200 of the display device 10. That is, the light-emitting element 300' may have a structure in which a plurality of layers are stacked in a direction perpendicular to the via layer 200 in a cross section.

[0186] Figure 8 is a schematic cross-sectional view showing a light-emitting element disposed between electrodes according to another embodiment.

[0187] Referring to Figure 8 , Figure 7The light-emitting element 300' may be disposed in the display device 10 according to an embodiment. The light-emitting element 300' is disposed such that the main body portion of the first conductive-type semiconductor 310' extends in a direction parallel to the via layer 200. Accordingly, the light-emitting element 300' may be disposed to have a structure in which the insulating film 380', the electrode material layer 370', the second conductive-type semiconductor 320', the active layer 330', and the first conductive-type semiconductor 310' are sequentially stacked perpendicular to the via layer 200 in its cross section. In addition, each layer of the light-emitting element 300' may be disposed to surround the outer surface of another layer and may have a symmetric structure based on the center of its cross section. That is, the light-emitting element 300' may have a structure in which the active layer 330', the second conductive-type semiconductor 320', the electrode material layer 370', and the insulating film 380' may be sequentially stacked based on the first conductive-type semiconductor 310'.

[0188] In addition, the insulating film 380 in the two end regions of the light-emitting element 300 that are in contact with the contact electrode 260 may be partially patterned and removed. When the second insulating layer 520 is patterned after the light-emitting element 300' is aligned, the insulating film 380' of the light-emitting element 300' may be partially removed such that the electrode material layer 370' and the first conductive-type semiconductor 310' may be partially exposed. Such an exposed region of the light-emitting element 300' may be in direct contact with the contact electrode 260.

[0189] In addition, Figure 7 the light-emitting element 300' includes an upper end portion and a lower end portion, and the side surfaces of the upper end portion and the lower end portion are inclined with respect to the main body portion. In the light-emitting element 300' disposed on the first insulating layer 510, the side surface of the main body portion may be in contact with the first insulating layer 510, and the inclined side surfaces of the upper end portion and the lower end portion may be spaced apart from the first insulating layer 510. Referring to Figure 8 , in the display device 10 according to an embodiment, the second insulating layer 520 may also be disposed in the partition region between the light-emitting element 300' and the first insulating layer 510. As described above, since the second insulating layer 520 includes an organic material, the second insulating layer 520 may even be disposed between the light-emitting element 300' and the first insulating layer 510 when the second insulating layer 520 can be formed. Accordingly, even when the light-emitting element 300' has inclined side surfaces, the light-emitting element 300' may be fixed to the first insulating layer 510. However, the present disclosure is not limited thereto.

[0190] In addition, the length h of the light-emitting element 300 may be in the range of 1 μm to 10 μm or in the range of 2 μm to 5 μm, and may preferably be about 4 μm. In addition, the light-emitting element 300 may have a diameter in the range of 300 nm to 700 nm, and the plurality of light-emitting elements 300 included in the display device 10 may have different diameters according to differences in the composition of the active layer 330. Preferably, the light-emitting element 300 may have a diameter of about 500 nm. The description of the length h and diameter of the light-emitting element 300 may be applied to the length h' and diameter (e.g., the diameter of the main body portion) of the light-emitting element 300'.

[0191] Hereinafter, a method of manufacturing the display device 10 according to an embodiment will be described with reference to Figures 9 to 15 A method of manufacturing the display device 10 will be described. Hereinafter, parts of the method of manufacturing the display device 10 will be described with reference to schematic cross-sectional views.

[0192] Figures 9 to 15 is a schematic cross-sectional view showing a method of manufacturing a display device according to an embodiment. Hereinafter, the process sequence of the method of manufacturing the display device 10 will be described in detail, and the structure, material, and function of the components formed in the manufacturing process of the display device 10 will be omitted. Specifically, only the structure of the display device 10 shown in Figures 9 to 15 is schematically shown, and the display device 10 according to an embodiment is not limited thereto.

[0193] First, with reference to Figure 9 a first base layer is provided, the first base layer including a first electrode 210 and a second electrode 220 disposed on the via layer 200 and a first insulating material layer 511 covering the first electrode 210 and the second electrode 220.

[0194] The shape and structure of the via layer 200, the first electrode 210, and the second electrode 220 are the same as those described above with reference to Figure 2 or Figure 4 However, different from that shown in Figure 2 the first insulating material layer 511 may be disposed on the via layer 200 to completely cover the via layer 200 and surround the first electrode 210 and the second electrode 220. The first insulating material layer 511 may be patterned in an operation to be described below to form the Figure 2 first insulating layer 510. In addition, it can be understood that, compared with Figure 4 the first base layer of Figure 9 is shown by omitting the plurality of dikes 410, 420, and 430. However, the present disclosure is not limited thereto, and the display device 10 according to an embodiment may be manufactured to include dikes 410, 420, and 430 as shown in Figure 4

[0195] In addition, Figure 9 the first insulating material layer 511 of Figure 5 may have a shape substantially the same as that of the first insulating layer 510 of Figure 9 That is, Figure 2 or Figure 4 a portion of the first insulating material layer 511 of Figure 5 may be patterned to form the first insulating layer 510 of

[0196] Next, referring to Figure 10 and Figure 11 a shielding electrode layer 800 is formed on the first insulating material layer 511 of the first base layer. As described above, the shielding electrode layer 800 may include a first shielding electrode 810 and a second shielding electrode 820, and the first shielding electrode 810 and the second shielding electrode 820 may respectively include a first recessed pattern portion 810C and a second recessed pattern portion 820C. Figure 10 is a cross-sectional view showing a region where the first recessed pattern portion 810C and the second recessed pattern portion 820C are formed in the first shielding electrode 810 and the second shielding electrode 820, Figure 11 is a cross-sectional view showing a region where the first recessed pattern portion 810C and the second recessed pattern portion 820C are not formed.

[0197] Figure 10 shows that a partial region of the first electrode 210 and the second electrode 220 is exposed through the recessed pattern portions 810C and 820C via the first insulating material layer 511, Figure 11 shows that the shielding electrodes 810 and 820 are provided to cover the first electrode 210 and the second electrode 220. The first insulating material layer 511 in the region where the recessed pattern portions 810C and 820C of Figure 10 are provided may be patterned and removed in the operations to be described below.

[0198] Next, referring to Figure 12 and Figure 13 a light-emitting element 300 is formed in the region exposed through the recessed pattern portions 810C and 820C between the first electrode 210 and the second electrode 220.

[0199] The method of aligning the light-emitting element 300 can be performed as follows: spraying a solution including the light-emitting element 300 on the electrodes 210 and 220 and the shielding electrodes 810 and 820; and applying an alignment power to each of the electrodes 210 and 220 to align the light-emitting element 300. The alignment power can form an electric field between the electrodes 210 and 220 to apply a dielectrophoretic force to the light-emitting element 300. The light-emitting element 300 can fall between the electrodes 210 and 220 in the solution due to the dielectrophoretic force.

[0200] In addition, the electric field generated by the alignment power can be formed only in the region where the first electrode 210 and the second electrode 220 are exposed through the recessed pattern portions 810C and 820C. As Figure 12 shown, the electric field E generated by the alignment power can be formed in the region where the electrodes 210 and 220 are exposed through the recessed pattern portions 810C and 820C. On the contrary, as Figure 13 shown, the first shielding electrode 810 and the second shielding electrode 820 completely overlapping the electrodes 210 and 220 can block the electric field E' formed by the alignment power. The light-emitting element 300 sprayed on the first electrode 210, the second electrode 220, and the shielding electrodes 810 and 820 can be aligned only in the region where the recessed pattern portions 810C and 820C are provided and thus the electric field E is formed, and cannot be aligned in the region where the shielding electrodes 810 and 820 are formed. Therefore, the light-emitting element 300 can be selectively aligned in the region where the recessed pattern portions 810C and 820C are formed.

[0201] Next, referring to Figure 14 , a second insulating material layer 521 is formed on the light-emitting element 300 and the shielding electrodes 810 and 820. The second insulating material layer 521 can be provided to completely cover the first base layer and the shielding electrodes 810 and 820. The second insulating material layer 521 can be patterned in the operations to be described below to form the second insulating layer 520.

[0202] Next, referring to Figure 15 , the second insulating material layer 521 and the first insulating material layer 511 under the recessed pattern portions 810C and 820C can be patterned to form the first insulating layer 510 and the second insulating layer 520, and a contact electrode 260 in contact with the electrodes 210 and 220, the light-emitting element 300, and the shielding electrodes 810 and 820 is formed. The contact electrode 260 can include a first contact electrode 261 and a second contact electrode 262, and the first contact electrode 261 and the second contact electrode 262 can be provided to be spaced apart from each other on the second insulating layer 520 formed on the light-emitting element 300. Since its description is the same as that described above, its detailed description will be omitted.

[0203] In addition, in some cases, such as Figure 2 as shown in Figure 2 , the second insulating layer 520 may be omitted, and the contact electrode 260 may be formed directly on the light-emitting element 300. In addition, another insulating layer may be provided on the shielding electrodes 810 and 820, or partial regions of the shielding electrodes 810 and 820 may be patterned such that the contact area between the contact electrode 260 and the first electrode 210 and the second electrode 220 can be increased. This will be described in detail below.

[0204] Next, although not shown in the drawings, a passivation layer 550 may be formed to cover the plurality of components provided on the via layer 200, thereby manufacturing the display device 10. In the display device 10 manufactured by the above process, the light-emitting element 300 is selectively aligned only in the regions of the recessed pattern portions 810C and 820C in which the shielding electrode layer 800 is formed, thereby improving the alignment of the light-emitting element 300 while reducing the number of light-emitting elements 300 aligned in unnecessary regions.

[0205] Hereinafter, the display device 10 according to other embodiments will be described.

[0206] Figure 16 is a plan view showing a display device according to another embodiment.

[0207] In the display device 10_1 according to an embodiment, the contact electrode 260_1 may contact both side portions of the shielding electrodes 810_1 and 820_1. Referring to Figure 16 , the shielding electrodes 810_1 and 820_1 may include recessed pattern portions 810C_1 and 820C_1 formed in their two side surfaces, and the contact electrode 260_1 may contact the shielding electrodes 810_1 and 820_1 and the electrodes 210_1 and 220_1 in the regions where the recessed pattern portions 810C_1 and 820C_1 are formed.

[0208] Specifically, the first shielding electrode branch portion 810B_1 provided on the first electrode branch portion 210B may include a first recessed pattern portion 810C_1 formed in its two side surfaces, and the second shielding electrode branch portion 820B_1 provided on the second electrode branch portion 220B may include a second recessed pattern portion 820C_1 formed in its two side surfaces. However, the first recessed pattern portion 810C_1 and the second recessed pattern portion 820C_1 formed in the facing side surfaces of the first shielding electrode branch portion 810B_1 and the second shielding electrode branch portion 820B_1 may be formed before the alignment of the light-emitting element 300, and the first recessed pattern portion 810C_1 provided on the outer side surface of the first shielding electrode branch portion 810B_1 may be provided when the contact electrode 260_1 is formed after the alignment of the light-emitting element 300.

[0209] That is to say, in the manufacturing process of the display device 10_1, the operation of forming the first recess pattern portion 810C_1 and the second recess pattern portion 820C_1 that expose the facing side surfaces of the first electrode 210_1 and the second electrode 220_1 can be separated from the operation of forming the first recess pattern portion 810C_1 that exposes the side surface opposite to the said side surface. When forming the contact electrode 260_1, as Figure 15 shown, the process of patterning the first insulating material layer 511 and the second insulating material layer 521 is performed. Here, two side portions of the first shielding electrode 810_1 and the second shielding electrode 820_1 can be patterned to form Figure 16 the display device 10_1. The descriptions of the shielding electrode main portions 810S_1 and 820S_1, the alignment region AA_1, and the non-alignment region NAA_1 are the same as those of the corresponding elements in the above embodiments.

[0210] Figure 17 is a schematic diagram showing Figure 16 a cross-section of the display device.

[0211] Referring to Figure 17 , different from the content shown in Figure 2 , in the display device 10_1 according to the embodiment, two side surfaces of each of the first shielding electrode 810_1 and the second shielding electrode 820_1 can be in contact with the contact electrode 260_1. Therefore, the first electrode 210_1 and the second electrode 220_1 can also be in contact with the contact electrode 260_1 at one end of the region where the light-emitting element 300 is provided and at the other end opposite to the said one end, respectively. Therefore, compared with the display device 10 in Figure 1 , in the display device 10_1 in Figure 16 , the contact electrode 260_1 can be in contact with the electrodes 210_1 and 220_1 and the shielding electrodes 810_1 and 820_1 in a larger area. Therefore, current can flow through the electrodes 210_1 and 220_1 safely. The descriptions of the first contact electrode 261_1, the second contact electrode 262_1, and the first insulating layer 510_1 are the same as those of the corresponding elements in the above embodiments.

[0212] In addition, the display device 10 according to an embodiment may further include a third insulating layer provided between the shielding electrode layer 800 and the contact electrode 260.

[0213] Figures 18 to 20 is a schematic diagram showing a cross-section of the display device according to other embodiments.

[0214] Referring to Figure 18, the display device 10_2 according to the embodiment may further include a third insulating layer 530_2 disposed on the first shielding electrode 810_2 and the second shielding electrode 820_2. When manufacturing the display device 10_2, after forming the shielding electrodes 810_2 and 820_2, the third insulating layer 530_2 may be disposed to cover the shielding electrodes 810_2 and 820_2, and then the third insulating layer 530_2 may be patterned and formed. The region between the first electrode 210_2 and the second electrode 220_2 where the light-emitting element 300 is aligned may be patterned. Thus, the third insulating layer 530_2 may be disposed on each of the first shielding electrode 810_2 and the second shielding electrode 820_2. In the manufacturing process of the display device 10_2 according to the embodiment, the third insulating layer 530_2 is disposed to cover the shielding electrodes 810_2 and 820_2, thereby effectively blocking the electric field formed by the alignment signal. In addition, since the third insulating layer 530_2 is disposed between the contact electrode 260_2 and the first shielding electrode 810_2 and the second shielding electrode 820_2, the electrical connection between them can be stabilized.

[0215] Except that a second insulating layer 520_3 is disposed on the light-emitting element 300, Figure 19 the display device 10_3 is the same as Figure 18 the display device 10_2. Except that the contact electrode 260_4 is in contact with two side surfaces of the third insulating layer 530_4 and the first shielding electrode 810_4 and the second shielding electrode 820_4, Figure 20 the display device 10_4 is the same as Figure 19 the display device 10_3. Since the description of their structures is the same as that described above, the detailed description thereof will be omitted. The description of the first contact electrodes 261_2 and 261_3, the second contact electrodes 262_2 and 262_3, the first insulating layers 510_2 and 510_3, the second insulating layer 520_4, the third insulating layer 530_3, the first shielding electrode 810_3, the second shielding electrode 820_3, and the electrodes 210_3 and 220_3 is the same as the description of the corresponding elements in the above embodiments.

[0216] Figure 21 is a cross-sectional view of a display device including a third insulating layer according to an embodiment.

[0217] Referring to Figure 21 , and being the same as Figure 4Unlike the display device 10, the first insulating layer 510_4 may be disposed on the upper surfaces of the first electrode 210_4 and the second electrode 220_4, and the first shielding electrode 810_4, the second shielding electrode 820_4, and the third insulating layer 530_4 may be disposed on the first insulating layer 510_4. The first contact electrode 261_4 and the second contact electrode 262_4 may be in contact with the side surfaces of the first electrode 210_4 and the second electrode 220_4, respectively, and may be in contact with the first insulating layer 510_4, the first shielding electrode 810_4, the second shielding electrode 820_4, and the third insulating layer 530_4 at the same time. The descriptions of the recessed pattern portions 810C_4 and 820C_4 are the same as those of the corresponding elements in the above embodiments.

[0218] In addition, the shielding electrode layer 800 of the display device 10 may be arranged not to overlap with the electrodes 210 and 220. The display device 10 according to an embodiment may include a shielding electrode layer 800 that forms one or more shielding electrode patterns, and the shielding electrode patterns may not overlap with the electrodes 210 and 220, but may be arranged only in the separation region between the electrodes 210 and 220.

[0219] Figure 22 is a plan view of a display device according to another embodiment. Figure 23 is along Figure 22 is a schematic cross-sectional view taken along line IIc-IIc' of Figure 24 is along Figure 22 is a schematic cross-sectional view taken along line IId-IId' of

[0220] Except that the shape of the shielding electrode layer 800_5 is different from that of the shielding electrode layer 800 of Figure 1 the display device 10_5 of Figure 22 is substantially the same as the display device 10 of Figure 1 The differences will be described in detail below.

[0221] Referring to Figure 22 the shielding electrode layer 800_5 of the display device 10_5 may include a plurality of shielding electrode patterns 830_5. The shielding electrode patterns 830_5 may be arranged to be spaced apart from each other in the first direction D1 and the second direction D2 in the separation region between the first electrode 210_5 and the second electrode 220_5 (for example, between the first electrode branch portion 210B_5 and the second electrode branch portion 220B_5).

[0222] The shielding electrode pattern 830_5 may be disposed on the first insulating layer 510_5 to form a pattern in the second direction D2, and the first insulating layer 510_5 may be exposed in a region where the shielding electrode pattern 830_5 is not disposed. That is, the first insulating layer 510_5 may also form a pattern in the second direction D2 in a plan view. In the manufacturing process of the display device 10_5, the region where the shielding electrode pattern 830_5 is not disposed and the first insulating layer 510_5 is exposed may be a region where an electric field is formed, and the region where the shielding electrode pattern 830_5 is disposed may be a region where the electric field is blocked. Accordingly, a plurality of light-emitting elements 300 may be disposed on the exposed first insulating layer 510_5 to form an alignment region AA_5, and the region where the shielding electrode pattern 830_5 is disposed may form a non-alignment region NAA_5.

[0223] Figure 23 is a cross-sectional view of a region where the first insulating layer 510_5 is exposed, including Figure 22 the alignment region AA_5 in the display device 10_5 of Figure 24 is a cross-sectional view of a region where the shielding electrode pattern 830_5 is disposed, including the non-alignment region NAA_5.

[0224] Referring to Figure 23 and Figure 2 different from the display device 10, the shielding electrode layer 800_5 may not be disposed on the first electrode 210_5 and the second electrode 220_5. The first insulating layer 510_5 may cover a part of the first electrode 210_5 and a part of the second electrode 220_5, and may be disposed between the first electrode 210_5 and the second electrode 220_5. Referring to Figure 24 in the cross-section including the non-alignment region NAA_5, the light-emitting element 300 is not disposed, and the first insulating layer 510_5 is disposed to completely cover the upper surfaces of the first electrode 210_5 and the second electrode 220_5. The shielding electrode layer 800_5 (i.e., the shielding electrode pattern 830_5) may be disposed on the first insulating layer 510_5, and may be disposed so as not to overlap with the first electrode 210_5 and the second electrode 220_5. Accordingly, the width w_5 of the shielding electrode pattern 830_5 may be the same as the separation distance S1_5 between the first electrode 210_5 and the second electrode 220_5.

[0225] The shielding electrode pattern 830_5 may be disposed between the first electrode 210_5 and the second electrode 220_5 and may be spaced apart from each other in one direction (e.g., in the first direction D1) to form a predetermined pattern. Even when an alignment signal is applied to the first electrode 210_5 and the second electrode 220_5, the shielding electrode pattern 830_5 disposed between the first electrode 210_5 and the second electrode 220_5 may block the electric field formed by the alignment signal.

[0226] In addition, according to one embodiment, the contact electrode 260_5 may not be disposed in the non-alignment region NAA_5, and the shielding electrode pattern 830_5 may be electrically insulated from the electrodes 210_5 and 220_5. Different from the display device 10 of Figure 1 , in the display device 10_5 of Figure 22 , the shielding electrode layer 800_5 may be insulated from the electrodes 210_5 and 220_5 to maintain a floating state. The description of the second insulating layer 520_5, the first contact electrode 261_5, the second contact electrode 262_5, and the electrode main portions 210S_5 and 220S_5 is the same as the description of the corresponding elements in the above embodiment.

[0227] In addition, the shielding electrode pattern may be partially overlapped with the first electrode 210 and the second electrode 220. The display devices 10_6 and 10_7 according to the embodiment may include one or more shielding electrode patterns 830_6 and 830_7 that are partially overlapped with the first electrode 210 and the second electrode 220.

[0228] Figure 25 is a plan view of a display device according to still another embodiment. Figure 26 is a cross-sectional view taken along line IIe-IIe' of Figure 25 .

[0229] Except that the shape of the shielding electrode pattern 830_6 is different from the shape of the shielding electrode pattern 830_5 of Figure 22 , the display device 10_6 of Figure 25 is substantially the same as the display device 10_5 of Figure 22 . Hereinafter, the differences will be described in detail.

[0230] Referring to Figure 25 , the shielding electrode layer 800_6 of the display device 10_6 may include a shielding electrode pattern 830_6 disposed between the first electrode branch portion 210B_6 and the second electrode branch portion 220B_6 to be partially overlapped with the first electrode branch portion 210B_6 and the second electrode branch portion 220B_6. The plurality of shielding electrode patterns 830_6 are provided to have a predetermined width w_6 and may be spaced apart from each other in the first direction D1 and the second direction D2.

[0231] As described above, the region where the shielding electrode pattern 830_6 is provided is the region where the electric field is blocked during the manufacturing process of the display device 10_6, and the misalignment region NAA_6 is formed therein. In addition, the region where the shielding electrode patterns 830_6 are spaced apart from each other may be the region where the first insulating layer 510_6 is exposed and thus an electric field is formed, and the light-emitting element 300 may be provided therein such that the alignment region AA_6 can be formed therein. In the shielding electrode pattern 830_6, any pattern may be spaced apart from another pattern in the second direction D2, and the first insulating layer 510_6 is exposed therebetween such that the alignment region AA_6 can be formed.

[0232] In addition, according to one embodiment, the width w_6 of the shielding electrode pattern 830_6 measured in one direction (e.g., in the first direction D1) may be greater than the separation region between the electrodes, that is, the separation distance S1_6 between the first electrode branch portion 210B_6 and the second electrode branch portion 220B_6. Different from Figure 22 the display device 10_5, in Figure 25 the display device 10_6, since the width w_6 of the shielding electrode pattern 830_6 is greater than the separation distance S1_6 between the first electrode branch portion 210B_6 and the second electrode branch portion 220B_6, the shielding electrode pattern 830_6 may partially overlap with the first electrode branch portion 210B_6 and the second electrode branch portion 220B_6.

[0233] Referring to Figure 26 , the shielding electrode patterns 830_6 provided on the first insulating layer 510_6 may be spaced apart from each other in the first direction D1 and may partially overlap with the first electrode 210_6 and the second electrode 220_6. On the other hand, the shielding electrode patterns 830_6 may be provided to be spaced apart from each other in the first direction D1 in the region overlapping with the second electrode 220_6. Therefore, it is possible to effectively block the electric field formed by the alignment signal during Figure 25 the manufacturing process of the display device 10_6. The description of the second insulating layer 520_6, the contact electrode 260_6, and the electrode main body portions 210S_6 and 220S_6 is the same as the description of the corresponding elements in the above embodiment.

[0234] Figure 27 is a plan view of a display device according to still another embodiment. Figure 28 is a cross-sectional view taken along the line IIf-IIf' of Figure 27 .

[0235] Except that the shape of the shielding electrode pattern 830_7 is different from the shape of Figure 25 the shielding electrode pattern 830_6, Figure 27The display device 10_7 and Figure 25 the display device 10_6 are substantially the same. The differences will be described in detail below.

[0236] Referring to Figure 27 and Figure 28 , a shielding electrode pattern 830_7 can be stacked with two first electrode branches 210B_7 and a second electrode branch 220B_7 at the same time. As shown in the accompanying drawings, the width w_7 of the shielding electrode pattern 830_7 can be greater than the sum of the widths of the electrode branches 210B_7 and 220B_7 and the separation distance S1_7 between the electrode branches 210B_7 and 220B_7. In this case, a plurality of shielding electrode patterns 830_7 can all extend in the first direction D1 and can be arranged to be spaced apart from each other only in the second direction D2. The description of the alignment region AA_7, the non-alignment region NAA_7, the electrodes 210_7 and 220_7, the shielding electrode layer 800_7, the first insulating layer 510_7, the second insulating layer 520_7, the contact electrode 260_7, and the electrode main bodies 210S_7 and 220S_7 is the same as the description of the corresponding elements in the above embodiments.

[0237] In addition, as described above with reference to Figure 1 , in the shielding electrode layer 800, recessed pattern portions 810C and 820C can be formed to expose at least partial regions of the electrodes 210 and 220. In this case, the facing side surfaces of the first electrode branch 210B and the second electrode branch 220B have a shape extending in one direction, and at least one side surface of the first shielding electrode 810 and the second shielding electrode 820 provided thereon can be recessed to form a pattern. However, the present disclosure is not limited thereto, and in some cases, the electrodes 210 and 220 can be arranged such that partial regions thereof protrude and do not overlap with the shielding electrode layer 800.

[0238] The electrodes 210 and 220 of the display device 10 according to an embodiment can include protruding pattern portions formed by protruding at least partial regions through their side surfaces, and the protruding pattern portions can not overlap with the shielding electrode layer 800.

[0239] Figures 29 to 32 is a plan view of a display device according to other embodiments.

[0240] First, referring to Figure 29, in the display device 10_8 according to the embodiment, at least partial regions of one side surface of the first electrode branch portion 210B_8 facing the second electrode branch portion 220B_8 and at least partial regions of two side surfaces of the second electrode branch portion 220B_8 facing the first electrode branch portion 210B_8 may protrude to form protruding pattern portions 210C_8 and 220C_8. The first electrode branch portion 210B_8 may include a first protruding pattern portion 210C_8 which is formed to protrude in a first direction D1 from one side surface thereof facing the second electrode branch portion 220B_8, and the second electrode branch portion 220B_8 may include a second protruding pattern portion 220C_8 which is formed to protrude in the first direction D1 from two side surfaces thereof facing the first electrode branch portion 210B_8. Side surfaces of the first shielding electrode branch portion 810B_8 and the second shielding electrode branch portion 820B_8 may have a shape extending in one direction, and the recessed pattern portions 810C and 820C may not be formed therein. Even in such a case, a separation distance S1_8 between the electrode branch portions 210B_8 and 220B_8 may be smaller than a separation distance S2_8 between the shielding electrode branch portions 810B_8 and 820B_8. The first protruding pattern portion 210C_8 and the second protruding pattern portion 220C_8 may not overlap with the first shielding electrode 810_8 and the second shielding electrode 820_8, and thus, an electric field generated by an alignment signal may be formed in the manufacturing process of the display device 10_8.

[0241] On the other hand, the first shielding electrode 810_8 and the second shielding electrode 820_8 may be arranged to overlap with regions of the first electrode branch portion 210B_8 and the second electrode branch portion 220B_8 where the protruding pattern portions 210C_8 and 220C_8 are not formed. This region is a region where an electric field caused by an alignment signal is blocked in the manufacturing process of the display device 10_8. Therefore, the light-emitting element 300 may be aligned on the protruding pattern portions 210C_8 and 220C_8 of the electrodes 210_8 and 220_8, and thus, an alignment region AA_8 may be formed, and a non-alignment region NAA_8 may be formed in a region where the electrodes 210_8 and 220_8 overlap with the shielding electrode layer 800_8. Descriptions of the contact electrode 260_8, the shielding electrode main portions 810S_8 and 820S_8, and the electrode main portions 210S_8 and 220S_8 are the same as those of the corresponding elements in the above embodiment.

[0242] Except that the contact electrode 260_9 has a shape extending in one direction (for example, in a second direction D2), Figure 30 the display device 10_9 of Figure 28is the same as the display device 10_8. Hereinafter, redundant descriptions will be omitted, and the differences will be mainly described.

[0243] The contact electrode 260 of the display device 10 may extend in the second direction D2 and may be partially disconnected to form a pattern. However, referring to Figure 29 , in the display device 10_9 according to the embodiment, the contact electrode 260_9 may extend in the second direction D2 to extend into the misalignment region NAA_9.
