[0084] FIG. 2 is a drawing illustrating an exemplary cross-section of the electronic device illustrated in FIG. 1c. FIG. 2 illustrates an exemplary cross-section of the electronic device (DD) viewed from a second direction (DR2). FIG. 2 omits some of the components of the electronic device (DD) described in FIG. 1c.

[0085] Referring to FIG. 2, the electronic device (DD) may include a display panel (DP), an input sensor (ISP), an anti-reflective layer (RPL), a window (WIN), a panel protection film (PPF), and first and second adhesive layers (AL1, AL2).

[0086] A display panel (DP) according to one embodiment of the present invention may be a light-emitting display panel. For example, the display panel (DP) may be an organic light-emitting display panel or an inorganic light-emitting display panel. The light-emitting layer of the organic light-emitting display panel may include an organic light-emitting material.

The input sensor (ISP) may be manufactured directly on the display panel (DP) during the manufacture of the electronic device (DD). Therefore, the input sensor (ISP) according to one embodiment may be placed directly on the display panel (DP). However, not limited thereto, the input sensor (ISP) may be manufactured as a separate panel from the display panel (DP) and attached to the display panel (DP) by an adhesive layer.

[0088] The anti-reflective layer (RPL) can be placed on the input sensor (ISP). The anti-reflective layer (RPL) can be manufactured directly on the input sensor (ISP) during the manufacture of the electronic device (DD). However, it is not limited thereto, and the anti-reflective layer (RPL) can be manufactured as a separate panel and attached to the input sensor (ISP) by an adhesive layer.

[0089] The anti-reflective layer (RPL) can be defined as an external light anti-reflective film. The anti-reflective layer (RPL) can reduce the reflectivity of external light incident from the electronic device (DD) toward the display panel (DP). External light may not be visible to the user due to the anti-reflective layer (RPL).

[0090] When external light traveling toward the display panel (DP) is reflected from the display panel (DP) and provided back to an external user, the user may perceive the external light as if through a mirror. To prevent this phenomenon, for example, the anti-reflection layer (RPL) may include a plurality of color filters that display the same color as the pixels of the display panel (DP).

[0091] Color filters can filter external light to the same color as the pixels. In this case, external light may not be visible to the user. However, not limited thereto, the anti-reflective layer (RPL) may include a phase retarder and / or polarizer to reduce the reflectivity of external light.

[0092] The window (WIN) can be placed on the anti-reflective layer (RPL). The window (WIN) can protect the display panel (DP), input sensor (ISP), and anti-reflective layer (RPL) from external scratches and impacts.

[0093] A panel protection film (PPF) may be placed under a display panel (DP). The panel protection film (PPF) may protect the lower part of the display panel (DP). The panel protection film (PPF) may include a flexible plastic material such as polyethyleneterephthalate (PET).

[0094] A first adhesive layer (AL1) is placed between a display panel (DP) and a panel protection film (PPF), and the display panel (DP) and the panel protection film (PPF) can be bonded together by the first adhesive layer (AL1). A second adhesive layer (AL2) is placed between a window (WIN) and an anti-reflection layer (RPL), and the window (WIN) and the anti-reflection layer (RPL) can be bonded together by the second adhesive layer (AL2).

[0194] In this embodiment, the first insulation pattern (IN1) may be configured to disconnect the P-type hole injection layer among the layers included in the common layer (CL-G1). Accordingly, the thickness of the first insulation pattern (IN1) may be thicker than the thickness of the P-type hole injection layer among the layers included in the common layer (CL-G1).

[0195] According to one embodiment, the width of the second insulating pattern (IN2) in cross-section may be greater than the width of the first insulating pattern (IN1). The difference in width may be formed due to the difference in etching rates with respect to the etching solution between the first insulating pattern (IN1) and the second insulating pattern (IN2).

[0196] According to one embodiment, a step difference may be formed between the portion of the second insulation pattern (IN2) that overlaps with the first partition pattern (W1) and the portion of the second insulation pattern (IN2) that does not overlap with the first partition pattern (W1). Accordingly, the thickness of the portion of the second insulation pattern (IN2) that overlaps with the first partition pattern (W1) may be greater than the thickness of the portion of the second insulation pattern (IN2) that does not overlap with the first partition pattern (W1).

[0197] Common layers (CL-G1, CL-B) included in different pixels (PXij, see FIG. 4B) are disconnected from each other with a partition (WL) in between by a first insulation pattern (IN1) and a second insulation pattern (IN2), and the disconnected common layers (CL-G1, CL-B) may come into contact with the sides of the first insulation pattern (IN1) and the second insulation pattern (IN2). However, this is not limited thereto, and the disconnected common layers (CL-G1, CL-B) may come into contact with the side (N1-S) of the first partition pattern (W1), and is not limited to any one embodiment.

[0198] A first barrier pattern (W1) is placed on a second insulation pattern (IN2). The first barrier pattern (W1) may include a metal. For example, the first barrier pattern (W1) may include aluminum. As the first barrier pattern (W1) includes aluminum, the side (N1-S) of the first barrier pattern (W1) may be oxidized and not conductive. Therefore, the side (N1-S) of the first barrier pattern (W1) may include an insulating region (N1-O).

[0199] A second bulkhead pattern (W2) may be placed on a first bulkhead pattern (W1). The second bulkhead pattern (W2) may include a metal different from that of the first bulkhead pattern (W1). For example, the second bulkhead pattern (W2) may include titanium.

[0200] According to the present embodiment, the thickness of the first partition pattern (W1) may be greater than the thickness of the second partition pattern (W2), and the width of the first partition pattern (W1) may be smaller than the width of the second partition pattern (W2). According to one embodiment, a portion of the second partition pattern (W2) may protrude from the first partition pattern (W1) and be exposed from the first partition pattern (W1).

[0201] Accordingly, the lower surface (N2-B) of the second barrier pattern (W2) may be exposed from the first barrier pattern (W1). This may be formed due to the difference in etching rates with respect to the etching solution between the first barrier pattern (W1) and the second barrier pattern (W2). The first barrier pattern (W1) and the second barrier pattern (W2) may be defined as having a tip structure.

[0202] According to one embodiment, the width of the second insulation pattern (IN2) may be equal to or greater than the width of the second partition pattern (W2), and is not limited to any one embodiment.

[0203] The second electrode (CE) can extend from the second light-emitting region (PXA-R) shown in FIG. 6 to the non-light-emitting region (NPXA) to cover the normal barrier (WA-N). The second electrode (CE) overlapping with the normal barrier (WA-N) can come into contact with the side (N1-S) of the first barrier pattern (W1), the lower surface (N2-B) of the second barrier pattern (W2) exposed from the first barrier pattern (W1), and the side (N2-S) of the second barrier pattern (W2).

[0204] According to one embodiment, the second electrode (CE) may include indium zinc oxide. The second electrode (CE) may be formed through a sputtering process.

[0205] As described above, since the side (N1-S) of the first bulkhead pattern (W1) includes an oxidized non-conductive region (N1-O), a portion of the second electrode (CE) covering the normal bulkhead (WA-N) can be connected to another portion of the second electrode (CE) through the lower surface (N2-B) of the second bulkhead pattern (W2) exposed from the first bulkhead pattern (W1) and the inner portion of the first bulkhead pattern (W1). The same description can be applied to the border bulkhead (WA-C).

[0206] According to one embodiment, the first thickness (TH1) of the second electrode (CE) disposed on the common layer (CL-G1, CL-B) may be greater than the second thickness (TH2) of the second electrode (CE) surrounding the normal partition (WA-N). The second thickness (TH2) may have a thickness of 20% to 25% relative to the first thickness (TH1).

[0207] A dummy pattern (CL-P) may be placed on the second partition pattern (W2). The dummy pattern (CL-P) may be covered by the second electrode (CE). For example, the dummy pattern (CL-P) may be entirely covered by the second electrode (CE). The dummy pattern (CL-P) is formed by the same process as the common layer (CL-G1, CL-B) and may contain the same material as the common layer (CL-G1, CL-B). The common layer (CL-G1, CL-B) may be disconnected on the second partition pattern (W2) by the tip structure of the partition (WL), and the disconnected portion of the common layer (CL-G1, CL-B) may be defined as the common layer (CL-G1, CL-B).

[0208] According to the present invention, by bringing a normal partition (WA-N) comprising different metal layers within a display area (DA) into contact with a second electrode (CE), the resistance of the second electrode (CE) can be reduced.

[0209] FIG. 8 is a cross-sectional view of a display panel according to an embodiment of the present invention. FIG. 8 is a cross-sectional view of a portion of the display panel (DP) that overlaps with a non-display area (NDA). Among the configurations described in FIG. 6, the barrier layer (BRL) disposed on the base substrate (SUB) to the fifth insulating layer (INS5) is briefly illustrated as an "insulating layer (INS)." At least one of the barrier layer (BRL) to the fifth insulating layer (INS5) may be omitted from the insulating layer (INS), and the embodiment is not limited to any one of the embodiments.

[0210] The display panel (DP) may include first and second dam sections (DMP-1, DMP-2) positioned at the outer edge of the non-display area (NDA). The first dam section (DMP-1) may be positioned adjacent to the display area (DA, see FIG. 6) relative to the second dam section (DMP-2). The first dam section (DMP-1) and the second dam section (DMP-2) may be positioned in the non-display area (NDA) to surround at least a portion of the contact area (CA).

[0211] Each of the first dam section (DMP-1) and the second dam section (DMP-2) may include dam patterns in which organic layers are stacked. Each of the dam patterns may include the same material as the layer containing organic material among the insulating layers described in FIG. 6.

[0212] The first dam portion (DMP-1) may include first to third dam patterns (D-1, D-2, D-3) sequentially stacked on an insulating layer (INS). The second dam portion (DMP-2) may include first to fourth dam patterns (D-1, D-2, D-3, D-4) sequentially stacked on an insulating layer (INS). The first to third dam patterns (D-1, D-2, D-3) may include the same material as the sixth insulating layer (INS6), the seventh insulating layer (INS7), and the pixel defining film (PDL). The fourth dam pattern (D-4) may include a material corresponding to a spacer that is placed on the pixel defining film (PDL) and serves as a support during the deposition process.

[0213] At least one of the first dam portion (DMP-1) and the second dam portion (DMP-2) can define the boundary of the organic layer (OL) in the non-display area (NDA). During the process of forming the organic layer (OL) through a solution process such as spin coating, slit coating, or inkjet process, the height of the first dam portion (DMP-1) can prevent the solution from overflowing.

[0214] According to the present invention, a non-display area (NDA) of a display panel (DP) may include a contact area (CA). The contact area (CA) may be defined as an area where a second electrode (CE) and a first electrode (AE), which are commonly disposed on a light-emitting element (OLED), come into contact.

[0215] A barrier (WL) may be disposed in the contact area (CA). More specifically, a border barrier (WA-C) included in the barrier (WL) may be disposed. The barrier (WL) may be disposed on the pixel defining film (PDL). In the contact area (CA), the pixel defining film (PDL) may have a second opening (PDL-OP2) that exposes at least a portion of the first electrode (AE). That is, the pixel defining film (PDL) may have first openings (PDL-OP1, see FIG. 6) that overlap with the first electrode (AE) included in each light-emitting element (OLED), and second openings (PDL-OP2) that expose portions of the first electrode (AE) disposed in a pattern in the non-display area (NDA).

[0216] FIG. 9a is a cross-sectional view of a contact area of ​​a display panel according to an embodiment of the present invention. FIG. 9b is a cross-sectional view of a contact area of ​​a display panel according to an embodiment of the present invention. FIG. 9a and FIG. 9b illustrate a shape in which border partitions (WA-C, WA-Ca) are arranged in a planar configuration.

[0217] Referring to FIG. 9a, the border partition (WA-C) may include first portions (WU) and second portions (WS). The first portions (WU) and second portions (WS) may be placed on the pixel definition film (PDL) and spaced apart from the second opening (PDL-OP2). The first portions (WU) and second portions (WS) are substantially one pattern, but for convenience of explanation, they will be described separately.

[0218] Each of the first parts (WU) may extend along the second direction (DR2) and be spaced apart along the first direction (DR1). Second parts (WS) may be placed between the first parts (WU). The first part (WU) closest to the display area (DA, see FIG. 6) among the first parts (WU) may be connected to a normal bulkhead (WA-N, see FIG. 7) extending from the display area (DA, see FIG. 6). Thus, the normal bulkhead (WA-N, see FIG. 7) may be in a pattern that is integral with the border bulkhead (WA-C).

[0219] According to the present embodiment, each of the second parts (WS) may have a stepped shape. The second parts (WS) may be spaced apart along the second direction (DR2) between two adjacent first parts (WU) along the first direction (DR1).

[0220] Referring to FIG. 9b, the border partition (WA-Ca) may include first portions (WU) and second portions (WS). The first portions (WU) and second portions (WS) may be placed on the pixel definition film (PDL) and spaced apart from the second opening (PDL-OP2). The first portions (WU) and second portions (WS) are substantially one pattern, but for convenience of explanation, they will be described separately.

[0221] Each of the first parts (WU) may extend along the second direction (DR2) and be spaced apart along the first direction (DR1). The second parts (WS) may be positioned between the first parts (WU).

[0222] According to the present embodiment, each of the second parts (WS) extends along the first direction (DR1) and can be spaced apart along the second direction (DR2) between two adjacent first parts (WU) along the first direction (DR1).

[0223] Figure 10 is a cross-sectional view taken along III-III' of Figure 9a.

[0224] Referring to FIG. 10, a border barrier (WA-C) may be disposed on a pixel defining film (PLD) in a contact area (CA). The border barrier (WA-C) may include the same layer structure as the normal barrier (WA-N) described in FIG. 7. The border barrier (WA-C) may include a first insulation pattern (IN1), a second insulation pattern (IN2), a first barrier pattern (W1), and a second barrier pattern (W2).

[0225] A first insulating pattern (IN1) may be disposed on a pixel defining film (PDL). The first insulating pattern (IN1) may include an inorganic material. A second insulating pattern (IN2) may be disposed on the first insulating pattern (IN1). The second insulating pattern (IN2) may include an inorganic material different from that of the first insulating pattern (IN1).

[0226] For example, the first insulation pattern (IN1) may include at least one of indium zinc oxide, indium gallium zinc oxide, and indium tin oxide, and the second insulation pattern (IN2) may include at least one of silicon oxide, silicon oxynitride, and silicon nitride.

[0227] In this embodiment, the first insulation pattern (IN1) may be configured to disconnect the P-type hole injection layer among the layers included in the common layer (CL-G1). Accordingly, the thickness of the first insulation pattern (IN1) may be thicker than the thickness of the P-type hole injection layer among the layers included in the common layer (CL-G1).

[0228] According to one embodiment, the width of the second insulating pattern (IN2) in cross-section may be greater than the width of the first insulating pattern (IN1). The difference in width may be formed due to the difference in etching rates with respect to the etching solution between the first insulating pattern (IN1) and the second insulating pattern (IN2).

[0229] According to one embodiment, the thickness of the second electrode (CE) may be greater than the thickness of the first insulation pattern (IN1). Therefore, even if the second electrode (CE) covers the border partition (WA-C), it may not be disconnected by the first insulation pattern (IN1).

[0230] According to one embodiment, a step difference may be formed in the portion of the second insulation pattern (IN2) that overlaps with the first partition pattern (W1) and in the portion of the second insulation pattern (IN2) that does not overlap with the first partition pattern (W1).

[0231] A first barrier pattern (W1) is placed on a second insulation pattern (IN2). The first barrier pattern (W1) may include a metal. For example, the first barrier pattern (W1) may include aluminum. As the first barrier pattern (W1) includes aluminum, the side (C1-S) of the first barrier pattern (W1) may be oxidized and not conductive. Therefore, the side (C1-S) of the first barrier pattern (W1) may include an insulating region (C1-O).

[0232] A second bulkhead pattern (W2) may be placed on a first bulkhead pattern (W1). The second bulkhead pattern (W2) may include a metal different from that of the first bulkhead pattern (W1). For example, the second bulkhead pattern (W2) may include titanium.

[0233] According to the present embodiment, the thickness of the first partition pattern (W1) may be greater than the thickness of the second partition pattern (W2), and the width of the first partition pattern (W1) may be smaller than the width of the second partition pattern (W2). According to one embodiment, a portion of the second partition pattern (W2) may protrude from the first partition pattern (W1) and be exposed from the first partition pattern (W1).

[0234] Accordingly, the lower surface (N2-B) of the second barrier pattern (W2) may be exposed from the first barrier pattern (W1). This may be formed due to the difference in etching rates with respect to the etching solution between the first barrier pattern (W1) and the second barrier pattern (W2). The first barrier pattern (W1) and the second barrier pattern (W2) may be defined as having a tip structure.

[0235] According to one embodiment, the width of the second insulation pattern (IN2) may be equal to or greater than the width of the second partition pattern (W2), and is not limited to any one embodiment.

[0236] A dummy pattern (CL-P) may be placed on the second partition pattern (W2). The dummy pattern (CL-P) may be covered by the second electrode (CE). For example, the dummy pattern (CL-P) may be entirely covered by the second electrode (CE). The dummy pattern (CL-P) is formed by the same process as the common layer (CL-G1, CL-B, see FIG. 7) and may contain the same material as the common layer (CL-G1, CL-B, see FIG. 7).

[0237] The insulation patterns and bulkhead patterns included in the normal bulkhead (WA-N) include the same material as the insulation patterns and bulkhead patterns included in the border bulkhead (WA-C) and can be patterned and formed by the same process.

[0238] The second electrode (CE) can be connected to the first electrode (AE) in the contact area (CA) of the non-display area (NDA). The second electrode (CE) is commonly placed in the light-emitting elements (OLED) described in FIG. 6 and can extend from the display area (DA) to the non-display area (NDA).

[0239] A second opening (PDL-OP2) that exposes a portion of the first electrode (AE) may be defined in the pixel defining film (PDL) overlapping with the contact area (CA). A second electrode (CE) extending into the non-display area (NDA) may cover the pixel defining film (PDL) and be connected to the first electrode (AE). A portion of the second electrode (CE) may cover a border barrier (WA-C) disposed on the pixel defining film (PDL).

[0240] In the contact region (CA), the second electrode (CE) can reduce the resistance of the second electrode (CE) by covering the border barrier (WA-C) which includes different metal layers.

[0241] According to the present invention, within the non-display area (NDA), the second electrode (CE) can be contacted with the first electrode (AE) through the border barrier (WA-C) with reduced resistance. Thus, a separate mask process for connecting the second electrode (CE) and the second power line (PL2, see FIG. 4b) through the normal barrier (WA-N) within the display area (DA) can be omitted. Thus, an electronic device (DD) with simplified manufacturing processes and costs can be provided.

[0242] FIG. 11 is a cross-sectional view of a contact area of ​​a display panel according to an embodiment of the present invention. FIG. 12 is a cross-sectional view of a contact area of ​​a display panel according to an embodiment of the present invention. FIG. 13 is a cross-sectional view of a contact area of ​​a display panel according to an embodiment of the present invention. Identical or similar reference numerals are used for configurations identical or similar to those described in FIG. 10, and redundant descriptions are omitted.

[0243] Referring to FIG. 11, a display panel (DP-1) according to one embodiment may include a border barrier (WA-C1) disposed in a contact area (CA) of a non-display area (NDA). The border barrier (WA-C1) may be disposed on a pixel defining film (PDL). The border barrier (WA-C1) may include a first insulating pattern (IN1) disposed on the pixel defining film (PDL), a second insulating pattern (IN2) disposed on the first insulating pattern (IN1), a first barrier pattern (W1) disposed on the second insulating pattern (IN2), and a second barrier pattern (W2) disposed on the first barrier pattern (W1).

[0244] According to the present embodiment, the first width (WD1) of the second insulation pattern (IN2) may be larger than the second width (WD2) of the second barrier pattern (W2). Accordingly, the side (I2-S) of the second insulation pattern (IN2) may protrude outward from the border barrier (WA-C) more than the side (C2-S) of the second barrier pattern (W2). The shape of the normal barrier (WA-N, see FIG. 7) may be the same as the shape of the border barrier (WA-C). Accordingly, when forming the common layer (CL-G1, CL-B, see FIG. 7), the thickness of the light-emitting layer included in the common layer (CL-G1, CL-B, see FIG. 7) can be secured, and the P-type hole injection layer included in the common layer (CL-G1, CL-B, see FIG. 7) can be easily disconnected.

[0245] Referring to FIG. 12, a display panel (DP-2) according to one embodiment may include a border barrier (WA-C2) disposed in a contact area (CA) of a non-display area (NDA). The border barrier (WA-C2) may be disposed on a pixel defining film (PDL). The border barrier (WA-C2) may include a first insulating pattern (IN1) disposed on the pixel defining film (PDL), a second insulating pattern (IN2) disposed on the first insulating pattern (IN1), a first barrier pattern (W1) disposed on the second insulating pattern (IN2), and a second barrier pattern (W2) disposed on the first barrier pattern (W1).

[0246] The border bulkhead (WA-C2) according to the present embodiment may further include a protective layer (PL). The protective layer (PL) may be placed on the second bulkhead pattern (W2) and covered by a dummy pattern (CL-P). The protective layer (PL) may be placed on the upper surface of the second bulkhead pattern (W2). The protective layer (PL) may be placed on the second bulkhead pattern (W2) to prevent the second bulkhead pattern (W2) from being damaged in a subsequent process.

[0247] The protective layer (PL) may include an inorganic material. For example, the protective layer (PL) may include at least one of silicon nitride and silicon oxide.

[0248] According to the present embodiment, a border bulkhead (WL-C2) having a robust tip structure can be provided as a protective layer (PL) is disposed on the second bulkhead pattern (W2). The normal bulkhead (WA-N) described in FIG. 7 may further include a protective layer (PL) as the border bulkhead (WL-C2).

[0249] Referring to FIG. 13, a display panel (DP-3) according to one embodiment may include a border barrier (WA-C3) disposed in a contact area (CA) of a non-display area (NDA). The border barrier (WA-C3) may be disposed on a pixel defining film (PDL). The border barrier (WA-C3) may include a first insulating pattern (IN1) disposed on the pixel defining film (PDL), a second insulating pattern (IN2) disposed on the first insulating pattern (IN1), a first barrier pattern (W1) disposed on the second insulating pattern (IN2), and a second barrier pattern (W2) disposed on the first barrier pattern (W1).

[0250] In this embodiment, a portion of the second bulkhead pattern (W2) exposed from the first bulkhead pattern (W1) may include a tip portion (TIP) bent downward. The normal bulkhead (WA-N) described in FIG. 7 may include the same tip portion (TIP) as the border bulkhead (WL-C2). Accordingly, according to this embodiment, as the second bulkhead pattern (W2) includes a tip portion (TIP), the common layer (CL-G1, CL-B, see FIG. 7) can be more easily disconnected at the border bulkhead (WA-C3).

[0251] Although the present invention has been described above with reference to preferred embodiments, those skilled in the art or those with ordinary knowledge in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and technical scope of the invention as described in the claims set forth below.

[0252] Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be determined by the claims.

[0253] The electronic device according to the present invention can provide an electronic device with simplified manufacturing processes and costs as electrodes are interconnected through a partition in a non-display area, and the electrode covering the partition, which includes different metal layers, has the effect of reducing resistance, thus having high industrial applicability.
