However, the present invention is not limited thereto, and the protruding member (DAM) and the bank (BK) may contain different materials and may have different structures.

[0078] The second non-display area (NDA2) may be located between the first non-display area (NDA1) and the third non-display area (NDA3).

The first inorganic encapsulation layer (IEL1) and the second inorganic encapsulation layer (IEL2) may form an inorganic film (IF). The inorganic film (IF) may cover the protruding member (DAM), the wiring portion (WP), and the bank (BK). That is, the above-mentioned inorganic film (IF) can be extended from the above-mentioned display area (DA) to the above-mentioned third non-display area (NDA3).

The second wiring (LN2) is placed on the first wiring (LN1), and the second wiring (LN2) may extend in a second direction (DR2) that intersects the first direction (DR1). Thus, the first wiring (LN1) and the second wiring (LN2) may intersect each other in the second non-display area (NDA2).

[0087] The first wiring (LN1) may be placed on the first insulating layer (IL1). The first wiring (LN1) may be placed on the same layer as the gate electrode (E1). The second wiring (LN2) may be placed on the second insulating layer (IL2). The second wiring (LN2) may be placed on the same layer as the upper electrode (E2).

[0088] Referring to FIGS. 4 and FIGS. 6, for example, the first direction (DR1) may mean a straight direction from the bank (BK) to the protruding member (DAM). For example, the second direction (DR2) may be a direction that intersects the first direction (DR1) diagonally (see FIG. 4). Or, the second direction (DR2) may be a direction that is orthogonal to the first direction (DR1) (see FIG. 6). However, embodiments according to the present invention are not limited thereto.

[0089] In one embodiment, in the second non-display area (NDA2), the first wires (LN1) and the second wires (LN2) intersect each other, so that no organic residue remains in the second non-display area (NDA2). Because the surface of the inorganic film (IF) is partially protruded due to the first wires (LN1) and the second wires (LN2), no organic residue remains in the second non-display area (NDA2). Therefore, moisture permeation through the organic residue in the second non-display area (NDA2) can be prevented. By having a structure in which the first wires (LN1) and the second wires (LN2) intersect each other, shrinkage of the display panel (display panel (DP) of FIG. 2) due to moisture permeation can be prevented.

[0090] FIGS. 7 and 8 are plan views showing other examples of FIG. 4. The first wiring (LN1) and the second wiring (LN2) according to FIGS. 7 and 8 may be identical to the first wiring (LN1) and the second wiring (LN2) of FIGS. 4 and 6, except for their arrangement relationship. Therefore, redundant descriptions may be omitted.

[0091] Referring to FIGS. 7 and 8, the first wiring (LN1) may extend in a second direction (DR2). The second wiring (LN2) is placed on the first wiring (LN1), and the second wiring (LN2) may extend in a first direction (DR1) that intersects the second direction (DR2). Thus, the first wiring (LN1) and the second wiring (LN2) may intersect each other in the second non-display area (NDA2).

[0092] For example, the first direction (DR1) may mean a straight direction from the bank (BK) to the protruding member (DAM). For example, the second direction (DR2) may be a direction that intersects the first direction (DR1) diagonally (see FIG. 7). Or, the second direction (DR2) may be a direction that is orthogonal to the first direction (DR1) (see FIG. 8). However, embodiments according to the present invention are not limited thereto.

[0093] FIG. 9 is a plan view showing another example of FIG. 4. FIG. 10 is a cross-sectional view taken along the line IV-IV' of FIG. 9.

[0094] Referring to FIGS. 9 and 10, the wiring section (WP) may further include third wirings (LN3). The third wirings (LN3) may be placed on a different layer from the first wirings (LN1) and the second wirings (LN2). For example, the third wirings (LN3) may be placed on the first insulating layer (IL1). Additionally, an additional sub-insulating layer (SIL) may be placed between the third wirings (LN3) and the first wirings (LN1). The sub-insulating layer (SIL) may be placed entirely over a display area, a first non-display area, a second non-display area, and a third non-display area (see FIG. 1). The sub-insulating layer (SIL) covers the third wirings (LN3) and may be placed on the first insulating layer (IL1). The first wirings (LN1) may be placed on the sub-insulating layer (SIL).

[0095] However, the present invention is not limited thereto, and in other embodiments, the third wiring (LN3) may be placed on a higher layer than the first wiring (LN1). Also, in yet another embodiment, the third wiring (LN3) may be placed on a higher layer than the second wiring (LN2).

[0096] The third wiring (LN3) may be extended in the first direction (DR1) as shown in FIG. 9. However, the present invention is not limited thereto, and in other embodiments, the third wiring (LN3) may be extended in a direction that intersects the first direction (DR1) diagonally or in a direction that is orthogonal to the first direction (DR1).

[0097] FIG. 11 is a plan view of a display device according to another embodiment of the present invention. FIG. 12 is a plan view of area B of FIG. 11 enlarged. FIG. 13 is a cross-sectional view taken along the VV' line of FIG. 12. FIG. 14 is a plan view showing another example of FIG. 12. Among the display devices (11) described with reference to FIG. 11 to FIG. 14, parts that overlap with the display device (10) described with reference to FIG. 1 may be omitted.

[0098] Referring to FIGS. 11 to 14, a second non-display area (NDA2) may be located between a first non-display area (NDA1) and a third non-display area (NDA3). In the second non-display area (NDA2), a substrate (SUB), a buffer layer (BFR) containing an inorganic material, a first insulating layer (IL1), a second insulating layer (IL2), a third insulating layer (IL3), and an inorganic film (IF) may be disposed.

[0099] In the second non-display area (NDA2), a wiring portion (WP) may be disposed on the substrate (SUB). The wiring portion (WP) may be connected to the data wiring (DL) in the first non-display area (NDA1) and may be connected to the pad (PD) in the third non-display area (NDA3).

[0100] In the second non-display area (NDA2), the inorganic film (IF) may protrude along the profile of the upper surface of another overlapping member. For example, in the second non-display area (NDA2), the inorganic film (IF) may overlap with the wiring portion (WP). The upper surface of the portion of the inorganic film (IF) that overlaps with the wiring portion (WP) may protrude along the profile of the upper surface of the wiring portion (WP).

[0101] In one embodiment, the wiring portion (WP) may include first wirings (LN1) and second wirings (LN2). The first wirings (LN1) may be placed on the same layer. The second wirings (LN2) may be placed on the same layer. The first wirings (LN1) and the second wirings (LN2) may be placed on different layers.

[0102] The first wiring (LN1) may be placed on the first insulating layer (IL1). The first wiring (LN1) may be placed on the same layer as the gate electrode (E1). The second wiring (LN2) may be placed on the second insulating layer (IL2). The second wiring (LN2) may be placed on the same layer as the upper electrode (E2).

[0103] The first wiring (LN1) may extend into a second direction (DR2) that intersects the first direction (DR1). The second wiring (LN2) may be arranged parallel to the first wiring (LN1). The second wiring (LN2) may be arranged alternately with the first wiring (LN1). The second wiring (LN2) may extend into the second direction (DR2).

[0104] For example, the first direction (DR1) may mean a straight direction from the bank (BK) to the protruding member (DAM). For example, the second direction (DR2) may be a direction that intersects the first direction (DR1) diagonally (see FIG. 12). Or, the second direction (DR2) may be a direction that is orthogonal to the first direction (DR1) (see FIG. 14). However, embodiments according to the present invention are not limited thereto.

[0105] In one embodiment, in the second non-display area (NDA2), the first wiring (LN1) and the second wiring (LN2) are extended in the second direction (DR2), which is diagonal or perpendicular to the first direction (DR1), so that no organic residue may remain in the second non-display area (NDA2). Because the surface of the inorganic film (IF) is partially protruded due to the first wiring (LN1) and the second wiring (LN2) extending in the second direction (DR2), no organic residue may remain in the second non-display area (NDA2). Therefore, moisture permeation through the organic residue in the second non-display area (NDA2) can be prevented. As a result, shrinkage of the display panel of the display device (11) (e.g., the display panel (DP) of FIG. 2) due to moisture permeation can be prevented.

[0106] FIGS. 15 and FIGS. 16 are plan views showing other examples of FIG. 12.

[0107] Referring to FIGS. 15 and 16, the first wiring (LN1) may extend in a first direction (DR1). The second wiring (LN2) is placed on the first wiring (LN1) and may extend in a second direction (DR2) that intersects the first direction (DR1). Thus, the first wiring (LN1) and the second wiring (LN2) may intersect each other in the second non-display area (NDA2).

[0108] For example, the first direction (DR1) may mean a straight direction from the bank (BK) to the protruding member (DAM). For example, the second direction (DR2) may be a direction that intersects the first direction (DR1) diagonally (see FIG. 15). Or, the second direction (DR2) may be a direction that is orthogonal to the first direction (DR1) (see FIG. 16). However, embodiments according to the present invention are not limited thereto.

[0109] FIG. 17 is an enlarged plan view of area C of FIG. 11. FIG. 18 is a cross-sectional view taken along the VI-VI' line of FIG. 17.

[0110] Referring to FIGS. 11, 17, and 18, in one embodiment, the wiring portion (WP) may be placed only in a portion of the second non-display area (NDA2). A dummy pattern portion (DMP) may be placed in the second non-display area (NDA2) on the substrate (SUB) where the wiring portion (WP) is not placed. The dummy pattern portion (DMP) may be spaced apart from the wiring portion (WP).

[0111] In one embodiment, the dummy pattern portion (DMP) may include first dummy patterns (DMP1) and second dummy patterns (DMP2). The first dummy patterns (DMP1) may be placed on the same layer. The second dummy patterns (DMP2) may be placed on the same layer. The first dummy patterns (DMP1) and the second dummy patterns (DMP2) may be placed on different layers.

[0112] Each of the first dummy patterns (DMP1) may have an island shape. That is, the first dummy patterns (DMP1) may not be connected to other electrodes or wiring. Similarly, each of the second dummy patterns (DMP2) may have an island shape. That is, the second dummy patterns (DMP2) may not be connected to other electrodes or wiring.

[0113] The first dummy patterns (DMP1) may be placed on the first insulating layer (IL1). The first dummy patterns (DMP1) may be placed on the same layer as the gate electrode (E1) and the first wiring (LN1). The second dummy patterns (DMP2) may be placed on the second insulating layer (IL2). The second dummy patterns (DMP2) may be placed on the same layer as the upper electrode (E2) and the second wiring (LN2).

[0114] In the second non-display area (NDA2), an inorganic film (IF) may be disposed. In the second non-display area (NDA2), the inorganic film (IF) may protrude along the profile of the upper surface of another overlapping member. For example, in the second non-display area (NDA2), the inorganic film (IF) may overlap with the wiring portion (WP) and the dummy pattern portion (DMP), respectively. The upper surface of the portion of the inorganic film (IF) that overlaps with the wiring portion (WP) and the dummy pattern portion (DMP) may protrude along the profile of the upper surface of the wiring portion (WP) and the dummy pattern portion (DMP).

[0115] The first dummy patterns (DMP1) may be extended in a third direction (DR3) that intersects the first direction (DR1). The second dummy patterns (DMP2) may be arranged side by side with the first dummy patterns (DMP1). The second dummy patterns (DMP2) may be arranged alternately with the first dummy patterns (DMP1). The second dummy patterns (DMP2) may be extended in the third direction (DR3).

[0116] For example, the first direction (DR1) may mean a straight direction from the bank (BK) to the protruding member (DAM). For example, the third direction (DR3) may be a direction that intersects the first direction (DR1) diagonally. Alternatively, the third direction (DR3) may be a direction that is orthogonal to the first direction (DR1). However, embodiments according to the present invention are not limited thereto.

[0117] Fig. 19 is a plan view showing another example of Fig. 17.

[0118] Referring to FIGS. 11 and 19, the first dummy patterns (DMP1) may extend in a third direction (DR3). The second dummy patterns (DMP2) are placed on the first dummy patterns (DMP1), and the second dummy patterns (DMP2) may extend in a first direction (DR1) that intersects the third direction (DR3). Thus, in a plane, the first dummy patterns (DMP1) and the second dummy patterns (DMP2) may intersect each other in the second non-display area (NDA2).

[0119] For example, the first direction (DR1) may mean a straight direction from the bank (BK) to the protruding member (DAM). For example, the third direction (DR3) may be a direction that intersects the first direction (DR1) diagonally. Alternatively, the third direction (DR3) may be a direction that is orthogonal to the first direction (DR1). However, embodiments according to the present invention are not limited thereto.

[0120] In one embodiment, the dummy pattern portion (DMP) is placed in the portion of the second non-display area (NDA2) where the wiring portion (WP) is not placed, so that no organic residue remains in the second non-display area (NDA2) as a whole. The surface of the inorganic film (IF) may be partially protruded due to the first dummy patterns (DMP1) and the second dummy patterns (DMP2) extending or intersecting in the third direction (DR3). Accordingly, no organic residue remains in the second non-display area (NDA2), and moisture permeation through the organic residue in the second non-display area (NDA2) can be prevented. As a result, shrinkage of the display panel of the display device (11) (e.g., the display panel (DP) of FIG. 2) due to moisture permeation can be prevented. Industrial applicability
