[0082] Each of the first signal lines (SL1) and the second signal lines (SL2) may include a line of the first layer and a line of the second layer disposed on different layers. The line of the first layer may be formed from the first conductive pattern layer (IS-CL1) of FIG. 4, and the line of the second layer may be formed from the second conductive pattern layer (IS-CL2). FIG. 5a illustrates, by way of example, a contact hole (TH-O) connecting the line of the first layer and the line of the second layer. The contact hole (TH-O) may penetrate the second insulating layer (IS-IL2, see FIG. 4).

[0083] Each of the first electrodes (E1-1 to E1-5) and the second electrodes (E2-1 to E2-4) may have a mesh shape in which a plurality of openings are defined. Each of the first electrodes (E1-1 to E1-5) and the second electrodes (E2-1 to E2-4) may include conductive lines defining a plurality of openings. The plurality of openings are defined to correspond to the light-emitting region (PXA, see FIG. 3) of the display panel (DP). The second electrodes (E2-1 to E2-4) intersect insulatedly with the first electrodes (E1-1 to E1-5). Either of the first electrodes (E1-1 to E1-5) and the second electrodes (E2-1 to E2-4) may have a single shape. In this embodiment, the first electrodes (E1-1 to E1-5) having a single shape are exemplified. The first electrodes (E1-1 to E1-5) may include sensing portions (SP1) and intermediate portions (CP1).

[0084] Each of the second electrodes (E2-1 to E2-4) may include sensing patterns (SP2) and bridge patterns (CP2, or connection patterns). Two adjacent sensing patterns (SP2) may be connected by two bridge patterns (CP2), but the number of bridge patterns is not limited. The bridge patterns (CP2) may be formed by patterning the first conductive pattern layer (IS-CL1) shown in FIG. 4, and a plurality of first electrodes (E1-1 to E1-5) and sensing patterns (SP2) may be formed by patterning the second conductive pattern layer (IS-CL2).

[0085] In order to show the relative positions of the line patterns (DMP1, DMP2) and the crack detection pattern (CRD) with respect to the input sensor (ISL), the line patterns (DMP1, DMP2) and the crack detection pattern (CRD) are shown in FIG. 5a.

[0087] Referring to FIG. 5b, a cross-section corresponding to II-II' in FIG. 5a is shown. The cross-section of the display panel (DP) corresponding to the display area (DP-DA) is described with reference to FIG. 4, so a detailed description is omitted. The light-emitting element (OLED) in FIG. 4 is shown briefly compared to the light-emitting element (OLED) in FIG. 3. A sensing portion (SP1) is disposed on a thin film encapsulation layer (TFE) within the display area (DP-DA). The sensing portion (SP1) is disposed between the second insulating layer (IS-IL2) and the third insulating layer (IS-IL3).

[0088] A voltage line (VL) is placed on the peripheral area (DP-NDA). The voltage line (VL) may be placed on the second insulating layer (20) of the display panel (DP). The voltage line (VL) may receive a low power supply voltage. The low power supply voltage is applied to the second electrode (CE). A connecting electrode (VL-E) is placed on the voltage line (VL), and the connecting electrode (VL-E) is connected to the second electrode (CE). The connecting electrode (VL-E) may be placed on the third insulating layer (30) of the display panel (DP).

[0089] A first line pattern (DMP1) is positioned to overlap with a voltage line (VL). The first line pattern (DMP1) can come into contact with a connecting electrode (VL-E). The first line pattern (DMP1) has a dam function in an inkjet process for forming an encapsulated organic layer (OL). A second line pattern (DMP2) is positioned outside the first line pattern (DMP1), and the second line pattern (DMP2) has the same function as the first line pattern (DMP1) and assists the first line pattern (DMP1).

[0090] The first line pattern (DMP1) includes a first layer (I1), a second layer (I2), and a third layer (I3). The first layer (I1) may be formed of the same material as the fourth insulating layer (40), the second layer (I2) may be formed of the same material as the fifth insulating layer (50), and the third layer (I3) may be formed of the same material as the pixel defining film (PDL). The second line pattern (DMP2) may further include a layer containing the same material as the third insulating layer (30) relative to the second line pattern (DMP2).

[0091] The first encapsulating inorganic layer (IOL1) and the second encapsulating inorganic layer (IOL2) overlap with the first line pattern (DMP1) and the second line pattern (DMP2), and are in contact on the outside of the first line pattern (DMP1). The first encapsulating inorganic layer (IOL1) and the second encapsulating inorganic layer (IOL2) can seal the encapsulating organic layer (OL). Additionally, the first encapsulating inorganic layer (IOL1) is in contact with the second insulating layer (20), which is an inorganic layer, and the second line pattern (DMP2) on the outside. The first encapsulating inorganic layer (IOL1) and the second insulating layer (20) can seal the organic layer between them.

[0092] A crack detection pattern (CRD) is disposed on the outside of the first insulating layer (10) and the second insulating layer (20). The crack detection pattern (CRD) may include a first layer containing the same material as the first insulating layer (10) and a second layer containing the same material as the second insulating layer (20). A crack detection pattern (CRD) containing inorganic material can detect cracks that occur and then expand at the edge of the display panel (DP).

[0093] A scan driving circuit (GDC) is placed between the voltage line (VL) and the display area (DP-DA). A transistor (TR-D) and a signal line (VL-int), which are components of the scan driving circuit (GDC), are illustrated as examples. The scan driving circuit (GDC) includes a plurality of stage circuits, each of which generates a scan signal, and the stage circuit includes a plurality of transistors. Figure 5b illustrates a single transistor (TR-D) as an example.

[0094] The transistor (TR-D) of the scan driving circuit (GDC) can be formed through the same process as the transistor (TR-P) of the pixel circuit. The transistor (TR-D) of the scan driving circuit (GDC) can have the same stacked structure as the transistor (TR-P) of the pixel circuit. The signal line (VL-int) can receive a clock signal or a bias voltage.

[0095] According to the present embodiment, an organic pattern (ORP) overlapping the surrounding area (DP-NDA) is disposed on a thin film encapsulation layer (TFE). Since the liquid organic material forming the encapsulation organic layer (OL) is provided uniformly within the display area (DP-DA), the encapsulation organic layer (OL) can provide a relatively flat upper surface within the display area (DP-DA). As the liquid organic material spreads outward, an inclined surface is naturally formed in the area adjacent to the first line pattern (DMP1). The liquid organic material hardens to form an encapsulation organic layer (OL) having an inclined surface. In other words, the thickness of the area of ​​the encapsulation organic layer (OL) adjacent to the display area (DP-DA) within the surrounding area (DP-NDA) is greater than the thickness of the area placed far from the display area (DP-DA).

[0096] Since the encapsulating organic layer (OL) is not placed on the outer side of the first line pattern (DMP1), a step (or curvature) is formed between the peripheral area (DP-NDA) and the display area (DP-DA). The organic pattern (ORP) eliminates the step formed between the peripheral area (DP-NDA) and the display area (DP-DA).

[0097] Referring to FIGS. 5a and 5b, the first signal line (SL1) can be superimposed on the line patterns (DMP1, DMP2). The organic pattern (ORP) provides a flat upper surface and can support the first signal line (SL1) in the area where the line patterns (DMP1, DMP2) are formed. FIG. 5b exemplarily illustrates a first signal line (SL1) comprising a first layer line (SL1-1) and a second layer line (SL1-2) connected by a contact hole (TH-O).

[0098] FIG. 5c is illustrated in a simplified manner compared to FIG. 5b, and the second encapsulation inorganic layer (IOL2) and the insulating layers (IS-IL1, IS-IL2, IS-IL3) of the input sensor (ISL) are not illustrated. Additionally, the first signal line (SL1) is illustrated as a single layer. The circuit element layer (DP-CL) and the display element layer (DP-OLED) are illustrated in a simplified manner.

[0099] Referring to FIGS. 5b and 5c, the organic pattern (ORP) may include a first part (ORP1) positioned outside the first line pattern (DMP1) and a second part (ORP2) positioned inside the first line pattern (DMP1) and overlapping with the encapsulated organic layer (OL). The part of the organic pattern (ORP) overlapping with the first line pattern (DMP1) may be defined as part of the first part (ORP1) or part of the second part (ORP2), and may be ignored as it has a relatively small area.

[0100] In this embodiment, the organic pattern (ORP) can come into contact with the second inorganic layer (IOL2). The organic pattern (ORP) can be formed immediately after the second inorganic layer (IOL2) is formed.

[0101] In a planar view, the first part (ORP1) has a larger area than the second part (ORP2). This is because the first part (ORP1) is placed in the area where the first signal line (SL1) is placed and the area where it is not, whereas the second part (ORP2) is placed centered on the area where the first signal line (SL1) is placed. Since the second part (ORP2) corresponds to a bridge supporting the first signal line (SL1), it is sufficient to secure the area supporting the first signal line (SL1).

[0102] By patterning the second part (ORP2) and making it discontinuous within the first direction (DR1), the tensile force exerted on the organic pattern (ORP) can be reduced even when tensile force is generated in the rolled state of the display module (DM), as illustrated in FIGS. 1a and 1b. Such an organic pattern (ORP) can be applied not only to a rollable display device but also to a foldable display device in which tensile force is generated.

[0103] Since the first part (ORP1) is placed in an area where the encapsulating organic layer (OL) is relatively thick compared to the first encapsulating inorganic layer (IOL1) and the second encapsulating inorganic layer (IOL2), the first part (ORP1) has a relatively larger thickness than the second part (ORP2). The thicknesses of the first part (ORP1) and the second part (ORP2) can be compared as average values.

[0104] An organic pattern (ORP) is placed between the surrounding area (DP-NDA) and the display area (DP-DA) to prevent a height difference from occurring in the layer where the first signal line (SL1) is placed. Due to the organic pattern (ORP), the first signal line (SL1) can be extended parallel to the sensing electrode from the sensing electrode (the sensing portion (SP1) in FIG. 5c). As a result, the gap between the second electrode (CE) and the first signal line (SL1) does not narrow even in the sloped area of ​​the encapsulated organic layer (OL). The coupling between the second electrode (CE) and the first signal line (SL1) can be maintained constant regardless of the shape of the encapsulated organic layer (OL).

[0105] The organic pattern (ORP) includes a negative-type photosensitive organic material, and its shape and thickness can be controlled according to the result of masking. A portion of the sufficiently exposed organic layer exists as a first portion (ORP1), and a portion of the organic layer whose exposure amount is controlled by the slit area of ​​the halftone mask exists as a second portion (ORP2). A portion of the unexposed organic layer is removed. A positive-type photosensitive organic material can be exposed in a manner opposite to that of a negative-type photosensitive organic material to form an organic pattern.

[0106] The first signal line (SL1) may include a first line portion (SL10) extended in a first direction (DR1) and a second line portion (SL20) extended from the first line portion (SL10) in a second direction (DR2). The first line portion (SL10) may be supported by a first portion (ORP1), and the second line portion (SL20) may be supported by a second portion (ORP2). Since the second portion (ORP2) has a smaller thickness compared to the first line portion (SL10), it can provide a substantially flat support surface with the first portion (ORP1) even when overlapping with the encapsulated organic layer (OL).

[0107] The first line portion (SL10) is positioned on the outside of the encapsulated organic layer (OL). The first signal line (SL1) shown in FIG. 5b corresponds to the position of the first line portion (SL10). The first line portion (SL10) may not overlap with the second electrode (CE). The coupling between the second electrode (CE) and the first signal line (SL1) may be reduced.

[0108] Referring to FIG. 5d, the first insulating layer (IS-IL1) of the input sensor (ISL) may have a multilayer structure. The first insulating layer (IS-IL1) may include a first inorganic layer (IS-IL11) and a second inorganic layer (IS-IL12) on the first inorganic layer (IS-IL11). Each of the first inorganic layer (IS-IL11) and the second inorganic layer (IS-IL12) may include at least one of silicon oxide, silicon oxynitride, silicon nitride, zirconium oxide, aluminum oxide, titanium oxide, and hafnium oxide. An organic pattern (ORP) may be disposed between the first inorganic layer (IS-IL11) and the second inorganic layer (IS-IL12).

[0109] Although not separately illustrated, in one embodiment of the present invention, an organic pattern (ORP) is positioned below the line (SL1-1) of the first layer in FIG. 5b, and the organic pattern (ORP) may contact the line (SL1-1) of the first layer and support the line (SL1-1) of the first layer. At this time, the stacked structure of the first insulating layer (IS-IL1) may be single layer or multi-layer.

[0111] FIGS. 6a to 6c are partial perspective views of an organic pattern (ORP) according to an embodiment of the present invention. Hereinafter, a detailed description of the same configuration as described with reference to FIGS. 5a to 5d is omitted.

[0112] Referring to FIGS. 6a through 6c, the first portion (ORP1) may include curved surface patterns (CSP) arranged along the first direction (DR1). Each of the curved surface patterns may provide a convex curve. The curved surface patterns can reduce the tensile force exerted on the organic pattern (ORP) even when tensile force is applied while the display module (DM) is rolled, as illustrated in FIGS. 1a and 1b. These curved surface patterns (CSP) can be applied not only to rollable displays but also to foldable displays where tensile force is applied.

[0113] As illustrated in FIG. 6a, the curved surface pattern (CSP) can provide a curved surface of a semi-cylindrical shape. The organic pattern (ORP) illustrated in FIG. 6a may be described as having defined valley regions (VA). Although one valley region (VA) is illustrated exemplarily in FIG. 6a, multiple valley regions (VA) may be arranged along a first direction (DR1). The valley region (VA) extends into a second direction (DR2) that intersects the first direction (DR1).

[0114] As illustrated in FIG. 6b, the curved surface pattern (CSP) can provide a curved surface in the shape of a half sphere. As illustrated in FIG. 6c, the second part (ORP2) can provide a convex curved surface instead of a flat surface. The second part (ORP2) can have a half cone shape.

[0115] As illustrated in FIGS. 6a to 6c, the organic pattern (ORP) may include a dye or a pigment. An organic pattern (ORP) having a predetermined color can prevent a structure placed below the organic pattern (ORP) from being visible to the outside.

[0117] FIG. 7a is a plan view of a display panel (DP) according to an embodiment of the present invention. FIG. 7b is an enlarged plan view of a part (AA) of FIG. 7a. FIG. 7c is a cross-sectional view corresponding to III-III' of FIG. 7b. FIG. 7d is a partial perspective view showing an organic pattern (ORP) and a signal line (SL1). FIG. 7e to 7g are plan views showing a part of an input sensor (ISL) superimposed on a part (AA) of the display panel (DP) shown in FIG. 7b.

[0118] Referring to FIG. 7a, the scan driving circuit (GDC) is placed overlapping the display area (DP-DA). Accordingly, the area for the scan driving circuit (GDC) in the peripheral area (DP-NDA) is unnecessary, and the area of ​​the peripheral area (DP-NDA) can be reduced.

[0119] Referring to FIG. 7b, the display area (DP-DA) includes a first display area (AA1), a second display area (AA2) outside the first display area (AA1), and a third display area (AA3) outside the second display area (AA2). A peripheral area (DP-NDA) is positioned outside the third display area (AA3).

[0120] A first pixel (PX1) is placed in a first display area (AA1), and a second pixel (PX2) is placed in a second display area (AA2). A third pixel (PX3) is placed in the second display area (AA2) and the third display area (AA3). Each of the first pixel (PX1), the second pixel (PX2), and the third pixel (PX3) may be provided in multiple numbers. Each of the first pixel (PX1), the second pixel (PX2), and the third pixel (PX3) may include a red pixel, a green pixel, and a blue pixel, and may further include a white pixel.

[0121] The first pixel (PX1) includes a first light-emitting element (OLED1) placed in the first display area (AA1) and a first pixel circuit (PC1) electrically connected to the first light-emitting element (OLED1) and placed in the first display area (AA1). The second pixel (PX2) includes a second light-emitting element (OLED2) placed in the second display area (AA2) and a second pixel circuit (PC2) electrically connected to the second light-emitting element (OLED2) and placed in the second display area (AA2). The third pixel (PX3) includes a third light-emitting element (OLED3) placed in the third display area (AA3) and a third pixel circuit (PC3) electrically connected to the third light-emitting element (OLED3) and placed in the second display area (AA2).

[0122] Each of the first light-emitting element (OLED1), the second light-emitting element (OLED2), and the third light-emitting element (OLED3) may be identical to the light-emitting element (OLED) shown in FIG. 3, and each of the first pixel circuit (PC1), the second pixel circuit (PC2), and the third pixel circuit (PC3) may include the transistor (TR-P) shown in FIG. 3. In FIG. 7b, a first electrode (AE) having a substantially rhombus shape is exemplarily illustrated to represent the first light-emitting element (OLED1), the second light-emitting element (OLED2), and the third light-emitting element (OLED3).

[0123] A scan driving circuit (GDC) formed through the same process as the first pixel circuit (PC1), the second pixel circuit (PC2), and the third pixel circuit (PC3) is disposed in the third display area (AA3). Accordingly, the third pixel circuit (PC3) cannot be disposed in the third display area (AA3), and the third pixel circuit (PC3) is disposed in the second display area (AA2).

[0124] Since the second pixel circuit (PC2) and the third pixel circuit (PC3) must be placed in the second display area (AA2), the second display area (AA2) has a lower resolution compared to the first display area (AA1). In other words, the second display area (AA2) has fewer pixels placed within a reference area than the first display area (AA1). The third display area (AA3) also has a lower resolution than the first display area (AA1). The resolutions of the second display area (AA2) and the third display area (AA3) can be substantially the same.

[0125] In order to prevent a decrease in brightness due to low resolution in the second display area (AA2) and the third display area (AA3), the second light-emitting element (OLED2) and the third light-emitting element (OLED3) have a relatively large light-emitting area. When the first color light-emitting area of ​​the second light-emitting element (OLED2) and the third light-emitting element (OLED3), e.g., a red light-emitting area, a green light-emitting area, or a blue light-emitting area, has a first area, the first color light-emitting area of ​​the first light-emitting element (OLED1) may have a second area that is smaller than the first area.

[0126] Since the first electrode (AE) of the third light-emitting element (OLED3) is positioned at a location spaced apart from the third pixel circuit (PC3), that is, at a location overlapping the scan driving circuit (GDC), the third pixel (PX3) may further include a connecting wire (TWL) for connecting the third light-emitting element (OLED3) and the third pixel circuit (PC3). The connecting wire (TWL) electrically connects the third light-emitting element (OLED3) placed in the third display area (AA3) and the third pixel circuit (PC3) placed in the second display area (AA2). The connecting wire (TWL) may include various materials such as metal, transparent conductive oxide, and conductive polymer, and is not limited to any one of them.

[0127] Referring to FIG. 7c, a first light-emitting element (OLED1), a second light-emitting element (OLED2), and a third light-emitting element (OLED3) are illustrated as examples. The connection relationship between the third light-emitting element (OLED3) and the transistor (TR-P3) of the third circuit (PC3) is illustrated as examples. A first connection electrode (CNE10) may be connected to the source or drain of the transistor (TR-P3) of the third circuit (PC3), a second connection electrode (CNE20) may be connected to the first connection electrode (CNE10), and a connection wire (TWL) may be connected to the second connection electrode (CNE20). The first electrode of the first light-emitting element (OLED1) may be connected to the connection wire (TWL). The third light-emitting element (OLED3) may be superimposed on the transistor (TR-D) of the scan driving circuit (GDC).

[0128] Referring to FIGS. 7c and 7d, a portion of the encapsulation organic layer (OL) overlapping the third display area (AA3) may provide an inclined surface. A second portion (ORP2) of the organic pattern (ORP) may overlap the surrounding area (DP-NDA) and the third display area (AA3). Referring to FIG. 7d, the second portion (ORP2) of the organic pattern (ORP) may be placed in the area between the third light-emitting elements (OLED3) spaced apart within the first direction (DR1). By not overlapping the third light-emitting elements (OLED3), the second portion (ORP2) of the organic pattern (ORP) may reduce interference with the source light generated from the third light-emitting elements (OLED3).

[0129] Referring to FIG. 7e, the second line portion (SL20) may be placed in the area between the third light-emitting elements (OLED3) spaced apart within the first direction (DR1). Additionally, the second line portion (SL20) may be placed in the area between the second light-emitting elements (OLED2) spaced apart within the first direction (DR1). By not overlapping the third light-emitting elements (OLED3) and the second light-emitting elements (OLED2), the second line portion (SL20) can reduce interference with the source light generated from the third light-emitting elements (OLED3) and the second light-emitting elements (OLED2).

[0130] Referring to FIG. 7e, the sensing portion (SP1) may overlap with the first display area (AA1). In the sensing portion (SP1), a plurality of first openings (MH1) corresponding to the first light-emitting elements (OLED1) are defined. Each of the plurality of first openings (MH1) may have an area larger than the opening (OP, see FIG. 3) corresponding to the first light-emitting element (OLED1). The sensing portion (SP1) may include conductive lines extending in a first diagonal direction (CDR1) and a second diagonal direction (CDR2) that intersect the first direction (DR1) and the second direction (DR2).

[0131] Referring to FIG. 7f, the sensing portion (SP1) may further overlap with the second display area (AA1). In the sensing portion (SP1), a plurality of second openings (MH2) corresponding to the second light-emitting elements (OLED2) are defined. Each of the plurality of second openings (MH2) may have a larger area than the opening (OP, see FIG. 3) corresponding to the second light-emitting element (OLED2). The second opening (MH2) may have a larger area than the first opening (MH1).

[0132] Referring to FIG. 7g, the sensing portion (SP1) may further overlap with the third display area (AA3). In the sensing portion (SP1), a plurality of third openings (MH3) corresponding to the third light-emitting elements (OLED3) are defined. Each of the plurality of third openings (MH3) may have an area larger than the opening (OP, see FIG. 3) corresponding to the third light-emitting element (OLED3). The third opening (MH3) may have substantially the same area as the third opening (MH3).
