Referring toFIG. 1andFIG. 2, a display device according to an exemplary embodiment of the present invention will be described.FIG. 1illustrates a plan view of a display device according to an exemplary embodiment of the present invention, andFIG. 2illustrates a cross-sectional view taken along a line II-II ofFIG. 1.

Referring toFIG. 1, the display device10includes a display area DA and a non-display area NDA. The display area DA displays an image, and the non-display area NDA is positioned around the display area DA. For example, the display device10includes a substrate100, and the substrate100may include the display area DA and the non-display area NDA.

The display area DA may include a plurality of pixels. For example, each of the pixels may include an organic light: emitting element or a liquid, crystal layer. For example, each pixel includes a first electrode, a second electrode, an organic light emitting element, and thin film transistors and signal lines electrically connected to the organic light emitting element. Further, the organic light emitting element may include an organic emission layer positioned between the first electrode and the second electrode. However, the present invention is not limited thereto. For example, each pixel nu it the first electrode, the second electrode, a liquid crystal layer, and thin film transistors and signal lines connected to the first electrode or the second electrode.

The non-display area NDA may be positioned to at least partially surround the display area DA. The non-display area NDA may include a sealing member400for sealing the display area DA, and a first blocking member500aand a second blocking member500bis disposed at opposite sides of the sealing member400.

The display device10may include two first edges E1, two second edges E2, and four corner portions C. The two first edges E1extend in a direction parallel to a first direction D1and face each other with the display area DA therebetween, and the two second edges E2extend in a direction parallel to a second direction D2different from the first direction D1and face each other with the display area DA therebetween. Further, the four corner portions C are positioned between the first edges E1and the second edges E2. Each of the corner portions C may be formed to have a curvature, but a shape of each corner portion C is not limited thereto. For example, the corner portions C may form right angles. A driving circuit210may be disposed adjacent to one of the two first edges E1, and a length of first edges E1and a length of the second edges E2may be different.

Referring toFIG. 2together withFIG. 1, the display device10includes a first substrate100a,a second substrate100b,a display element200, and the sealing member400disposed between the first substrate100aand the second substrate100b.The first substrate100amay face the second substrate100b.In addition, the display device10may include a touch unit300, the first blocking member500a,and the second blocking member500b.

The second substrate100bis disposed to be spaced apart from the first substrate100aalong a third direction D3that is substantially perpendicular to the first direction D1and the second direction D2and that is substantially perpendicular to surfaces of the first substrate100aand the second substrate100b.For example, the second substrate100bmay be an encapsulation substrate for encapsulating the display element200.

The display element200may include a plurality of pixels.

The touch unit300is disposed at a position overlapping the display element200along the third direction D3, and may sense a touch input from the outside. Herein, the touch input includes when an external object such as a user's hand directly touches a touch surface of the display device10and when the external object approaches the touch surface of the display device10or hovers in a state in which the external object approaches the touch surface of the display device10.

The touch unit300may be disposed in the display area DA, but the present invention is not limited thereto. For example, a portion of the touch unit300may be disposed in the non-display area NDA.

The sealing member400may be cured after being heated through light energy such as a laser beam, and the display element200disposed in the display area DA may be sealed by bonding the first substrate100aand the second substrate100bto each other.

The first blocking member500aand the second blocking member500bmay be spaced apart from each other, and may be disposed at opposite sides of the sealing member400, from a plan view, to not overlap the sealing member400along the third direction D3. However, the present invention is not limited thereto. For example, so edges of the first blocking member500aand the second blocking member500bmay overlap the sealing member400along the third direction D3, and in this case, most of the first blocking member500aand the second blocking member500bmay not overlap the sealing member400along the third direction D3.

When light such as a laser beam is irradiated to the sealing member400, the first blocking member500aand the second blocking member500bmay prevent light from being irradiated to sides of a position where the sealing member400is to be formed, thereby preventing the sealing member400from being widened. When the first blocking member500aand the second blocking member500bare not disposed around a region where the sealing member400is to be formed, light such as a laser beam may be irradiated to a peripheral region around a region where the sealing member400is to be formed so that the sealing member400is disposed not only in the region where the sealing member400is to be formed, but also in the peripheral region of the region where the sealing member400is to be formed, thereby increasing a width of the sealing member400. The first blocking member500aand the second blocking member500bmay not allow light to pass through the peripheral region of the region where the sealing member400is to be formed, thereby preventing the width of the sealing member400from being widened beyond a predetermined point.

The non-display area NDA positioned at a first edge E1of the display device10will be described in more detail with reference toFIG. 3together withFIG. 1andFIG. 2.FIG. 3illustrates an enlarged view showing an enlarged portion A ofFIG. 1.

Referring toFIG. 3, the non-display area NDA includes the first blocking member500aand the second block member500b.The first blocking member500amay be disposed between the first edge E1and the sealing member400, and the second blocking member500bmay be disposed between the sealing member400and the touch unit300, on a plane formed by intersection of the first direction D1and the second direction D2.

The first blocking member500aincludes a first group blocking patterns50including a plurality of first blocking patterns50a,a plurality of second blocking patterns50b,and a plurality of third blocking patterns50cpositioned sequentially from the sealing member400toward the first edge E1. The first blocking patterns50aare arranged in the first direction D1parallel to the first edge E1, and the second blocking patterns50bare arranged along the first direction D1. The third blocking patterns50care arranged along the first direction D1. For example, the first blocking patterns50a,the second blocking patterns50b,and the third blocking patterns50cmay be disposed in lines along the first direction D1.

In each of the first blocking patterns50a,the second blocking patterns50b,and the third blocking patterns50c,a length of an edge thereof parallel to the first direction D1is longer than that of an edge thereof parallel to the second direction D2. For example, each of the first blocking patterns50a,the second blocking patterns50b,and the third blocking patterns50cmay have a rectangular shape. However, the present invention is not limited thereto.

Edges parallel to the second direction D2among edges of the first blocking patterns50ado not overlap edges parallel to the second direction D2among edges of the second blocking patterns50b,along the second direction D2. Similarly, edges parallel to the second direction D2among edges of the second blocking patterns50bdo not overlap edges parallel to the second direction D2among edges of the third blocking patterns50c,along the second direction D2. For example, the first blocking patterns50amay be misaligned with the second blocking patterns50b,and the second blocking patterns50bmay be misaligned with the third blocking patterns50c.

The second blocking member500bincludes a second group of blocking patterns51including a plurality of fourth blocking patterns51a,a plurality of fifth blocking patterns51b,and a plurality of sixth blocking patterns51csequentially positioned from the sealing member400toward the touch unit300. The fourth blocking patterns51aare arranged along the first direction D1parallel to the first edge E1, and the fifth blocking patterns51bare arranged along the first direction D1. The sixth blocking patterns51care arranged in the first direction D1. For example, the fourth blocking patterns51a,the fifth blocking patterns51b,and the sixth blocking patterns51cmay be disposed in lines along the first direction D1.

In each of the fourth blocking patterns51a,the fifth blocking patterns51b,and the sixth blocking patterns51c,a length of an edge thereof parallel to the first direction D1is longer than that of an edge thereof parallel to the second direction D2. For example, each of the fourth blocking patterns51a,the fifth blocking patterns51b,and the sixth blocking patterns51cmay have a rectangular shape. However, the present invention is not limited thereto.

Edges parallel to the second direction D2among edges of the fourth blocking patterns51ado not overlap edges parallel to the second direction D2among edges of the fifth blocking patterns51b,along the second direction D2. Similarly, edges parallel to the second direction D2among edges of the fifth blocking patterns51bdo not overlap edges parallel to the second direction D2among edges of the sixth blocking patterns51c,along the second direction D2. For example, the fourth blocking patterns51amay be misaligned with the fifth blocking patterns51b,and the fifth blocking patterns51bmay be misaligned with the six blocking patterns51c.

As such, edges of the third blocking patterns50c,the second blocking patterns50b,and the first blocking patterns50aof the first blocking member500amay be not disposed in a line, but may be disposed in a zigzag form along the second direction D2. In addition, edges of the fourth blocking patterns51a,the fifth blocking patterns51b,and the sixth blocking patterns51cof the second blocking member500bmay be disposed in a zigzag form along the second direction D2without being disposed in a line.

As described above, static electricity, etc, may be prevented from flowing into the touch unit300and the display element200along the edges of the blocking patterns50c,50b,and50abecause the edges of the blocking patterns50c,50b,and50amay be disposed closer to the first edge E1of the display device10than to the touch unit300and the display element200. In addition, static electricity, etc. may be prevented from flowing into the touch unit300and the display element200along the edges of the blocking patterns51a,51b,and51cbecause edges of the blocking patterns51a,51b,and51cmay be disposed in a line along a direction between the touch unit300and the first blocking member500a.For example, the blocking patterns51a,51b,and51cmay be closer to the first edge of the display device10than to the touch unit300and the display element200.

This will be described in more detail later.

The non-display area NDA positioned at a corner portion C of the display device10will be described in more detail with reference toFIG. 4together withFIG. 1andFIG. 2.FIG. 4illustrates an enlarged view showing a portion B ofFIG. 1.

Referring toFIG. 4, the non-display area NDA of the corner portion C includes the first blocking member500aand a second blocking member500b.The first blocking member500ais disposed between an edge of the display device10and the sealing member400, and the second blocking member500bis disposed between the sealing, member400and the touch unit300, on a plane formed by intersection of the first direction D1and the second direction D2.

The first blocking member500aincludes a plurality of seventh blocking patterns52a,and the second blocking member500bincludes a plurality of eighth blocking patterns52b.The seventh blocking patterns52aand the eighth blocking patterns52bmay be disposed to be spaced apart from each other along the edge of the display device10and the edge of the sealing member400.

Each of the blocking patterns52aand52bof the non-display area NDA adjacent to the corner portion C described with reference toFIG. 4have a polygonal shape such as a rectangular shape, and the blocking patterns52aand52bmay be arranged alongside the edges of the corner portion C, unlike the non-display area NDA positioned on an edge extending in a direction without forming a curved surface among the edges of the display device10illustrated inFIG. 3.

In addition, the blocking patterns of the display device according to an exemplary embodiment of the present invention will be described in more detail with reference toFIG. 5.FIG. 5illustrates an enlarged view showing a blocking pattern of a display device according to an exemplary embodiment of the present invention.

The first blocking member500aof the non-display area NDA positioned on an edge extending in a direction without forming a curved surface among the edges of the display device illustrated inFIG. 3will be described as an example with reference toFIG. 5.

Referring toFIG. 5, a first length L1of a third edge E11parallel to the first direction D1is longer than a second length L2of a fourth edge E22parallel to the second direction D2in each of the first blocking patterns50a,the second blocking patterns50band the third blocking patterns50c.

The fourth edge E22of each of the first blocking patterns50adoes not overlap the fourth edge E22of each of the second blocking patterns50balong the second direction D2. Similarly, the fourth edge E22of each of the second blocking patterns50bdoes not overlap the fourth edge E22of each of the third blocking patterns50calong the second direction D2.

A virtual first center line CC1extending through central portions of the first blocking patterns50aand extending along the second direction D2may be positioned between the fourth edges E22of the adjacent two second blocking patterns50b.A virtual second center line CC2extending through central portions of the second blocking patterns50band extending along the second direction D2may be positioned between the fourth edges E22of the two adjacent third blocking patterns50c.

In addition, a shape or disposal of the blocking patterns51a,51b,and51cof the second blocking member500bis similar to that of the blocking patterns50a,50b,and50cof the first blocking member500aillustrated inFIG. 5.

A movement of electrostatic particles that can be introduced from the outside will be conceptually described with reference toFIG. 6andFIG. 7.FIG. 6illustrates a schematic view showing a movement of electrostatic particles (e.g., charged particles) in a display device according to an exemplary embodiment of the present invention, andFIG. 7illustrates a schematic view showing a movement of electrostatic particles in a general display device according to a comparative example.

Referring toFIG. 6, when electrostatic particles P are introduced into any one of the third blocking patterns50cfrom the outside, the introduced electrostatic particles P may move toward an edge of a third blocking patterns50c,that is adjacent to the electrostatic particles P, along a first path P1, and then may move toward another third blocking pattern50calong a second path P2or may move toward an edge of a second blocking pattern50b,that is adjacent to the electrostatic particles P, along a third path P3.

The electrostatic particles moved along the second path P2may move toward another third blocking pattern50cthat is adjacent thereto or may move toward another adjacent second blocking pattern50bthat is adjacent thereto.

The electrostatic particles moved along the third path P3may move again toward the edge of the second blocking pattern50balong a fourth path P4, and may move again toward an edge of a first blocking pattern50athat is adjacent thereto along a fifth path P5. The electrostatic particles moved through the fifth path P5may move toward another edge or corner in the first blocking pattern50aalong a sixth path P6, and then may move toward the blocking patterns51a,51b,and51cof the second blocking member500balong a seventh path P7. The electrostatic particles P may move in the blocking patterns51a,51b,and51cof the second blocking member500bsimilar to the movement in the first blocking member500a.

As described above, when the electrostatic particles introduced into the first blocking member500afrom the outside move toward the touch unit300and the display element200from the first edge E1of the display device, they do not linearly move along the second direction D2, but move in a direction that is a combination of the first direction D1and the second direction D2(e.g., a direction that crosses the first direction D1and the second direction D2). As described above, the length of the third edge E11parallel to the first direction D1is relatively longer than the length of the fourth edge E22parallel to the second direction D2among the edges of the blocking patterns50c,50b,and50aof the first blocking member500a,and thus a movement distance of the electrostatic particles becomes longer than when linearly moving toward the second direction D2. In addition, the fourth edge E22of each of the third blocking patterns50cdo not overlap to the fourth edge E22of each of the second blocking patterns50b,and the fourth edge E22of each of the third blocking patterns50coverlaps a central portion of an adjacent second blocking pattern50balong the second direction D2. As such, it may difficult for the electrostatic particles to linearly move toward the second direction. D2by disposing the fourth edges E22of the blocking patterns50c,50b,and50ato not overlap each other in the second direction D2. For example, the blocking patterns50c,50b,and50amay be adjacent to each other along the second direction D2.

As such, since the movement path of the electrostatic particles that can be introduced from the outside becomes long, it may be difficult for the electrostatic particles to move to the touch unit300and the display element200, and they may decrease in size or disappear before reaching to the touch unit300and the display element200. Accordingly, it is possible to prevent static electricity from flowing into the touch unit300and the display element200through the first blocking member500aand the second blocking member500bwhile preventing the width of the sealing member400from being widened, by forming the first blocking member500aand the second blocking member500b.

A comparative example in which two blocking members5000aand5000bare formed to have a plate shape at opposite sides of the sealing member400will now be described with reference toFIG. 7. Referring toFIG. 7, the electrostatic particles P introduced from the outside may move in a linear direction through the two blocking members5000aand5000bto the touch unit300along three paths P11P12, and P13. As such, the electrostatic particles introduced from the outside may move to the touch unit300and the display element200through a short path as compared with the first blocking member500aand the second blocking member500bof the display device according to the exemplary embodiment of the present invention.

Now, one experimental example be described with reference toFIG. 8.FIG. 8illustrates a schematic view showing some regions of an edge of a display device according to an experimental example.

In this experimental example, Table 1 shows a comparison of a first width W1and a second width W2. The first width W1is of a region of the sealing member400where a material layer of the sealing member400is stacked, and the second width W2is of an actually formed sealing member400according to each region when the sealing member400is formed at a portion of the first edge E1, of the display device10, connected to a driving circuit unit by irradiating light without forming the blocking members500aand500b.

FIG. 8illustrates regions of the portion of the first edge E1of the display device connected to the driving circuit unit. A first region1ofFIG. 8, which is a region where a driving signal line is positioned, may be, e.g., a region where a second power line ELVSS is positioned, and each of a second region2and a third region3, which are regions where a driving signal line is positioned, may be, e.g., a region where a first power line ELVDD is positioned. Each of a fourth region4and a fifth region5may be a region where a crack detection line surrounding the non-display area NDA is positioned. Each of the sixth region6and a seventh region7may be a region where a label for distinguishing cells in a manufacturing process is disposed. An eighth region8may be a region in which detection signal lines connected to the touch unit300are positioned, and a ninth region9may be a region in which the driving signal line, e.g., the second power line ELVSS, is disposed as in the first region1.

Referring to Table 1, when a blocking member is not formed around the sealing member400, it was found that a difference between a first width W1, of a region where a material layer constituting sealing member400was actually stacked, and a second width W2, of the sealing member400actually formed, was about 100 μm or more. As described above, it has been found that, when a blocking member is not formed around the sealing ember400, a width of the sealing member400becomes larger than a desired value, thereby making it difficult to reduce a width of the non-display area NDA.

Now, another experimental example will be described with reference to Tables 2 and 3 together withFIG. 9toFIG. 11.FIG. 9toFIG. 11illustrate examples of a blocking pattern of a display device according to an experimental example.

In this experimental example, a display device was formed five times for a first case (case1) where the first blocking member500aand the second blocking member500bare formed around the sealing member400as in the display device according to an exemplary embodiment of the present invention, and for a second case (case2), a third case (case3), and a fourth case (case4) where blocking members are formed as illustrated inFIG. 9toFIG. 11For each case, all other conditions were the same, and only the position and shape of the blocking members were different, and then a voltage of a constant magnitude was applied from the outside to measure whether or not a problem occurs in the touch portion (or, e.g., touch unit) of the display device due to static electricity. Table 2 shows a result of applying a voltage of 10 kV from the outside, and Table 3 shows a result of applying a voltage of 8 kV from the outside.

Referring toFIG. 9, in the second case (case2), a blocking member5000abaying a plate shape was formed between the first edge E1of the display device and the sealing member400, and a blocking member5000bincluding a plurality of blocking patterns5a,5b,5c,and5dextending along the first direction D1was formed between the sealing member400and the touch unit300.

Referring toFIG. 10, in the third case (case3), a plurality of blocking members5000c,having edges disposed in a line along the first direction D1and the second direction D2, were formed between the first edge E1and the sealing member400of the display device, and blocking member was formed between the sealing member400and the touch, unit300.

Referring toFIG. 11, in the fourth case (case4), a plate-shaped blocking member5000dwas formed in the seventh region7ofFIG. 8, in which the actual width of the sealing member is the widest, in the result of the previous experimental example, and no blocking member was formed between the sealing member400and the touch unit300.

Referring to Table 3 andFIG. 4, it was found that one case caused a problem in the touch unit due to static electricity, and the rest did not cause a problem in the touch unit due to static electricity among cases in which a voltage of 10 kV was applied from the outside, in the first case (case1) where the first blocking member500aand the second blocking member500bwere formed around the sealing member400as in the display device according to an exemplary embodiment of the present invention. It was found that a problem occurred in the touch unit due to static electricity when a voltage of 10 kV was applied from the outside (See Table 2) and a voltage of 8 kV was applied from the outside (See Table 3) in the second case (case2) where the blocking member was formed as illustrated inFIG. 9.

It was found that a problem occurred one time among 5 times in the touch unit due to static electricity when a voltage of 10 kV was applied and a voltage of 8 kV was applied from the outside in the third case (case3) where the blocking member was formed as illustrated inFIG. 10.

It was found that no problem occurred in the touch unit due to static electricity when a voltage of 10 kV was applied from the outside, but a problem occurred 3 times among 5 times in the touch unit due to static electricity when a voltage of 8 kV was applied from the outside in the fourth case (case4) where the blocking member was formed as illustrated inFIG. 11.

As such, according to an exemplary embodiment of the present invention, it is possible to prevent a sealing member disposed in a non-display area of a display device from widening to prevent widening of the non-display area and to prevent static electricity from entering the display device from the outside to prevent damage to the display area by static electricity, by forming a blocking member having a rectangular shape around a region where the sealing member is disposed. Further, the blocking member has a longer edge in a direction parallel to an edge of the display device, and includes a plurality of blocking patterns in which edges are not disposed side by side along a direction from the edge of the display device toward the touch unit. For example, the edges of the plurality of blocking patterns may be misaligned with one another in the direction from the edge of the display device toward the touch unit.
