[0018] FIGS. 1A and FIGS. 1B illustrate examples of a stacked structure of a display panel.

[0019] FIGS. 1A and FIGS. 1B illustrate an example of a stacked structure of a display panel (100). For example, the display panel (100) may include at least a portion of the display module (860) of FIG. 8. For example, the display panel (100) may be an example of the display panel (910) of FIG. 9. The display panel (100) may be referred to as a display or a display device.

[0020] For example, a display panel (100) may include pixels. Each of the pixels may include subpixels. The subpixels may include a first subpixel configured to emit light in a first color (e.g., red), a second subpixel configured to emit light in a second color (e.g., green), and a third subpixel configured to emit light in a third color (e.g., blue). As an example without limitation, the subpixels may further include a fourth subpixel configured to emit light in a fourth color (e.g., white).

[0021] FIGS. 1A and FIGS. 1B illustrate an example of a stacked structure of a display panel (100). A pixel (or subpixel) of the display panel (100) may be included within the stacked structure of the display panel (100).

[0022] Referring to FIG. 1a, a display panel (100) may include a glass substrate (110), a thin film transistor (TFT) layer (120), a first electrode layer (130), a light-emitting layer (140), a second electrode layer (150), and an encapsulation layer (160). The glass substrate (110), the TFT layer (120), the first electrode layer (130), the light-emitting layer (140), the second electrode layer (150), and the encapsulation layer (160) included within the stacked structure of the display panel (100) as illustrated in FIG. 1a may be examples of light-emitting elements (e.g., organic light-emitting diodes (OLEDs)) that constitute pixels (or subpixels) of the display panel (100).

[0023] For example, the glass substrate (110) may be a layer on which a plurality of layers are disposed. The glass substrate (110) may be referred to as a basis layer. For example, a TFT layer (120) may be disposed on the glass substrate (110).

[0024] For example, the TFT layer (120) may include a plurality of TFTs. For example, the TFTs may include LTPS (low temperature polycrystalline silicon), LTPO (low temperature polycrystalline oxide), or oxide TFTs. For example, each of the TFTs in the TFT layer (120) may be electrically connected to a subpixel (or pixel) and used as a switch to control the subpixel (or pixel). For example, controlling the subpixel may include controlling the light emission of the subpixel.

[0025] For example, the first electrode layer (130) may be disposed on the TFT layer (120). For example, the first electrode layer (130) may be disposed on one side (or top side) of the TFT layer (120). For example, the first electrode layer (130) may include an anode (or positive electrode). For example, the anode may be electrically connected to the TFT of the TFT layer (120).

[0026] For example, a light-emitting layer (140) may be disposed on a first electrode layer (130). For example, the light-emitting layer (140) may be disposed on one side (or top side) of the first electrode layer (130). For example, the light-emitting layer (140) may include light-emitting portions. For example, the light-emitting portions may include an organic material that emits light of a color according to a subpixel. Although not shown in FIG. 1a, the light-emitting layer (140) may include an insulating portion. For example, the insulating portion may be a portion for defining the light-emitting portion. However, the present disclosure is not limited thereto. For example, the insulating portion may be disposed on the first electrode layer (130) as a layer (or insulating layer) distinct from the light-emitting layer (140). For example, the insulating portion or the insulating layer may be referred to as a pixel define layer (PDL).

[0027] Although not illustrated in FIG. 1a, the display panel (100) may include layers related to holes and layers related to electrons. For example, the layers related to holes may include a hole injection layer (HIL) and a hole transfer layer (HTL). For example, the layers related to electrons may include an electron transfer layer (ETL) and an electron injection layer (EIL). For example, the HIL may be placed on a first electrode layer (130), and the HTL may be placed on the HIL. For example, the ETL may be placed on a light-emitting layer (140), and the EIL may be placed on the ETL. In the above example, the HIL, the HTL, the ETL, and the EIL are described as being included in the display panel (100) as separate layers, but the present disclosure is not limited thereto. For example, layers related to holes may be included within the first electrode layer (130) or the light-emitting layer (140). For example, layers related to electrons may be included within the light-emitting layer (140) or the second electrode layer (150).

[0028] For example, the second electrode layer (150) may be disposed on the light-emitting layer (140). For example, the second electrode layer (150) may be disposed on one side (or top side) of the light-emitting layer (140). For example, the second electrode layer (150) may include a cathode (or negative electrode).

[0029] For example, the encapsulation layer (160) may be disposed above the second electrode layer (150). For example, an air layer (155) may be formed between the encapsulation layer (160) and the second electrode layer (150). For example, the encapsulation layer (160) may be supported by a support member (165). For example, the support member (165) may be disposed on a glass substrate (110) and used to support the encapsulation layer (160). In the example of FIG. 1a, the encapsulation layer (160) is described as being distinct from the support member (165), but the present disclosure is not limited thereto. For example, the support member (165) may be included in the encapsulation layer (160) (or part of the encapsulation layer (160)).

[0030] In the case of the display panel (100) illustrated in FIG. 1a, while the display panel (100) is not displaying an image (or while the pixels (or subpixels) of the display panel (100) are not driving, or while the OLED is not emitting light), the visibility of the black color may be poor. This may be because the reflectivity of light is increased by the air layer (155) of the display panel (100). Additionally, in the case of the display panel (100) illustrated in FIG. 1a, while the display panel (100) is displaying an image (or while the pixels (or subpixels) of the display panel (100) are driving, or while the OLED is emitting light), unintended visual effects may occur in the image displayed through the display area of ​​the display panel (100). For example, the visual effects may include the display of a pattern of shape such as Newton's rings, or a change in color tone. To solve problems that may arise in a display panel (100) including an air layer (155) of FIG. 1a, a filling material may be used. An example of a display panel (100) including a filling material may be referenced in FIG. 1b.

[0031] FIG. 1b illustrates an example of a stacked structure of a display panel (100) that includes a filling material (170) instead of an air layer (155) in the display panel (100) of FIG. 1a. The layers included in the stacked structure of the display panel (100) of FIG. 1b may correspond to the layers included in the stacked structure of the display panel (100) of FIG. 1a. In other words, the specific details regarding the layers of the stacked structure of the display panel (100) of FIG. 1b may be substantially the same as the details regarding the layers of the stacked structure of the display panel (100) of FIG. 1a.

[0032] Referring to FIG. 1b, the display panel (100) may include a filling material (170) between the second electrode layer (150) and the encapsulation layer (160). The filling material (170) may be referred to as a resin. For example, the filling material (170) may be filled within the display panel (100) before the second electrode layer (150) is covered by the encapsulation layer (160). For example, the filling material (170) may be composed of an organic material or an organic compound. As an example, but not limited to, the filling material (170) may be composed of a polymer. As an example, but not limited to, the polymer may include polymethyl methacrylate (PMMA). For example, the filling material (170) may be hardened after being filled (or applied) within the air layer (155) of FIG. 1a.

[0033] In the case of the display panel (100) illustrated in FIG. 1b, the problem caused by the display panel (100) of FIG. 1a can be resolved by using a filler material (170). However, in the case of the display panel (100) of FIG. 1b, when the filler material (170) is cured, a chemical change may occur at the point where the filler material (170) and the support member (165) come into contact. For example, the support member (165) may be composed of frit (or glass pieces). After placing the support member (165) on the glass substrate (110), the filler material (170) may begin to fill the display panel (100) while the support member (165) is curing. At this time, since no pattern is formed on one side (e.g., the top side) of the second electrode layer (150), there may be no elements that hinder the movement (or flow) of the filling material (170) applied to the second electrode layer (150). Accordingly, the filling material (170) in an uncured state may come into contact with the support member (165) before the curing of the support member (165) is completed. Subsequently, while the filling material (170) and the support member (165) are each cured, the chemical change may occur. As the chemical change occurs, a crack (or void) may form within the support member (165). Accordingly, peeling of the display panel (100) may occur due to the crack formed within the support member (165).

[0034] Figure 2 illustrates an example of peeling caused in a display panel of an electronic device.

[0035] For example, the electronic device (200) may be implemented in various form factors. For example, the electronic device (200) may include not only an electronic device including a bar-type display panel (100), as shown in FIG. 2, but also an electronic device including a display panel (100) that is a flexible display. For example, the flexible display may include an electronic device including a foldable display, an electronic device including a multi-foldable display, or an electronic device including a rollable display. Additionally, for example, the electronic device (200) may include a tablet PC. Additionally, for example, the electronic device (200) may be implemented as a wearable device. For example, the wearable device may include a head-mounted display (HMD) or a watch-shaped device. However, the present disclosure is not limited thereto. The electronic device (200) of FIG. 2 may be an example of the electronic device (801) of FIG. 8. For example, the electronic device (200) of FIG. 2 may include at least a part of the electronic device (801) of FIG. 8.

[0036] For example, the display panel (100) of the electronic device (200) may be a display panel (100) having a stacked structure as illustrated in FIG. 1b. As described above, delamination may occur in the display panel (100) depending on a chemical change between the filler material (170) and the support member (165). For example, the delamination may occur in the side portion (205) of the display panel (100). For example, the side portion (205) may include a certain range from the edge of the display panel (100). For example, a dark point may occur in the side portion (205) as a crack occurs in the support member (165) located in the display panel (100) within the side portion (205). For example, the dark point may be caused by unintended light emission due to the crack in the light-emitting portions of the light-emitting layer (140) corresponding to the side portion (205).

[0037] Referring to FIGS. 1a, 1b, and 2, as described above, when a display panel (100) includes an air layer (155) or fills a filling material (170) within the display panel (100), the quality of the display panel (100) may be reduced. Hereinafter, the present disclosure proposes a structure of a display panel (100) to improve the said quality reduction. For example, the display panel (100) may include a protruding structure for controlling the movement (or flow) of the filling material (170) so that the filling material (170) comes into contact with the support member (165) after the hardening of the support member (165) is completed, even if the filling material (170) is filled before the support member (165) is hardened. For example, the protruding structure may be formed on one side of a second electrode layer (150) to which the filling material (170) is applied. For example, the protruding structure may include a protruding pattern (or control pattern) and a dam. For example, the protruding pattern may be formed along the extension of the protrusion. The present disclosure can prevent delamination of the side portion (205) (or edge region) of the display panel (100) and improve the quality of the display panel (100) by controlling the movement of the filler material (170) using the protruding structure. For example, the display panel (100) according to the present disclosure may have low breathability to moisture or oxygen into the display panel (100) (or the side portion (205) of the display panel (100)) using the protruding structure. Accordingly, the present disclosure can prevent dark spots and oxidation that may occur in the display panel (100).

[0038] FIG. 3 illustrates examples of a method for manufacturing a display panel using an electrode layer having a protruding pattern formed thereon.

[0039] FIG. 3 illustrates examples (301, 302) of a method for manufacturing a display panel (100) using an electrode layer having a protruding pattern formed thereon. For example, the electrode layer having a protruding pattern formed thereon may be a second electrode layer (150). The layers included in the stacked structure of the display panel (100) of FIG. 3 may correspond to the layers included in the stacked structure of the display panel (100) of FIG. 1a and FIG. 1b. In other words, the specific details regarding the layers of the stacked structure of the display panel (100) of FIG. 3 may be substantially the same as the details regarding the layers of the stacked structure of the display panel (100) of FIG. 1a and FIG. 1b. Examples (301, 302) illustrate an example of the stacked structure of the display panel (100) when the display panel (100), cut parallel to the xy plane, is viewed from the z-axis direction.

[0040] Example (303) of FIG. 3 illustrates an example of the second electrode layer (150) in the xz plane when the second electrode layer (150) is viewed from the y-axis direction. Referring to Example (303), protruding patterns (310, 320) can be formed on the second electrode layer (150) of the display panel (100). For example, after sequentially stacking the glass substrate (110), TFT layer (120), first electrode layer (130), light-emitting layer (140), second electrode layer (150), and encapsulation layer (160) of the display panel (100), protruding patterns (310, 320) can be formed on the second electrode layer (150).

[0041] For example, a protruding pattern (310) may be formed on the second electrode layer (150) centered at a location (315). For example, a protruding pattern (320) may be formed on the second electrode layer (150) centered at a location (325). For example, the location (315) may represent the center of the protruding pattern (310). As an example without limitation, the location (315) may be a location of the light-emitting portion of the light-emitting layer (140) or an insulating layer (or insulating portion). For example, the location (325) may represent the center of the protruding pattern (320). As an example without limitation, the location (325) may be a location of the light-emitting portion of the light-emitting layer (140) or an insulating layer (or insulating portion). For example, the protrusion pattern (310) (or, protrusion pattern (320)) may have a concentric object shape with respect to a position (315) (or,, position (325)). In the example of FIG. 3, the concentric object shape of the protrusion pattern (310) may be a concentric rectangle. However, the present disclosure is not limited thereto. For an example of a protrusion pattern having a different concentric object shape, FIG. 6 may be referenced below.

[0042] Referring to Example (301), after forming the protruding patterns (310, 320), a filling material may be applied. For example, the filling material may begin to be applied to a specific area of ​​the second electrode layer (150). In one example, the filling material (370-1) may be applied to a first area (350-1) of the second electrode layer (150), the filling material (370-2) may be applied to a second area (350-2) of the second electrode layer (150), and the filling material (370-3) may be applied to a third area (350-3) of the second electrode layer (150). In other words, the filling material may not be applied to all areas of the second electrode layer (150), but may be applied to only a portion of the second electrode layer (150). For example, the first region (350-1), the second region (350-2), and the third region (350-3) may correspond to a portion of the second electrode layer (150) on which a protruding pattern (e.g., protruding pattern (310), or protruding pattern (320)) is formed. In example (301), the encapsulation layer (160) may be spaced apart from (or not coupled to) the support member (165).

[0043] Referring to example (302), after the filling material (170) is filled into the display panel (100), the encapsulation layer (160) can be combined with the support member (165). For example, the filling material (170) may include filling materials (370-1, 370-2, 370-3). As the encapsulation layer (160) is combined (or compressed) with the support member (165), the movement (or flow) of the filling material (170) may be controlled (or reduced) by the protruding patterns (310, 320) of the second electrode layer (150). In other words, the filling material (170) may spread relatively slowly by the protruding patterns (310, 320) compared to the second electrode layer (150) which does not include the protruding patterns (310, 320).

[0044] Referring to Example (302), after the curing of the support member (165) and the filler material (170) is completed, the sealing of the display panel (100) can be completed. For example, the curing may include curing by ultraviolet light and / or curing by a laser.

[0045] As described above, the protrusion patterns (310, 320) formed on the second electrode layer (150) can be used to control the movement (or flow) of the filling material (170). In this case, each of the protrusion patterns (310, 320) may include a protrusion (352) to obstruct the movement (or flow) of the filling material (170). For example, each of the protrusion patterns (310, 320) may include lines (or belts) of the protrusion (352) formed as the protrusion (352) included in the second electrode layer (150) extends along the insulating layer (or PDL). For example, the protrusion (352) included in the second electrode layer (150) may protrude (or extend) from the base (351) of the second electrode layer (150). A specific example of the protrusion (352) included in the second electrode layer (150) is illustrated and described with reference to FIG. 4.

[0046] FIG. 4 illustrates an example of a stacked structure of a display panel including an electrode layer including a protrusion.

[0047] FIG. 4 illustrates an example of a stacked structure of a display panel (100) including a second electrode layer (150) including a protrusion (352) of FIG. 3. The layers included in the stacked structure of the display panel (100) of FIG. 4 may correspond to the layers included in the stacked structure of the display panel (100) of FIG. 3. In other words, the specific details regarding the layers of the stacked structure of the display panel (100) of FIG. 4 may be substantially the same as the details regarding the layers of the stacked structure of the display panel (100) of FIG. 3. For example, the second electrode layer (150) may include a protrusion pattern (e.g., the protrusion patterns (310, 320) of FIG. 3, or the protrusion (352) of FIG. 3).

[0048] Referring to FIG. 4, the display panel (100) may include a first electrode layer (130), a light-emitting layer (140), a second electrode layer (150), an encapsulation layer (470), and a filter layer (480). In FIG. 4, for convenience of explanation, the display panel (100) is depicted as not including a glass substrate (110) and a TFT layer (120), but the present disclosure is not limited thereto. For example, the TFT layer (120) may be disposed below the first electrode layer (130) of FIG. 4. For example, the glass substrate (110) may be disposed below the TFT layer (120). Additionally, the encapsulation layer (470) of FIG. 4 may include the encapsulation layer (160) of FIG. 3, a support member (165), and a filling material (170). For example, after the curing of the support member (165) and the filling material (170) is completed, the bag layer (470) may include (or be referred to as) one or more layers comprising the bag layer (160), the support member (165), and the filling material (170) of FIG. 3.

[0049] Referring to FIG. 4, a light-emitting layer (140) may be disposed on a first electrode layer (130). For example, the light-emitting layer (140) may include a first light-emitting portion (441) and a second light-emitting portion (442). For example, the light-emitting portions (441, 442) may include an organic material that emits light of a color according to a subpixel. The first light-emitting portion (441) may be spaced apart from the second light-emitting portion (442). For example, an insulating layer (446) may be disposed between the first light-emitting portion (441) and the second light-emitting portion (442). In the above example, the light-emitting layer (140) is described as a layer distinct from the insulating layer (446), but the present disclosure is not limited thereto. For example, the light-emitting layer (140) may be a layer comprising the insulating layer (446) (or an insulating portion). For convenience of explanation, the light-emitting layer (140) is described below as a layer distinct from the insulating layer (446).

[0050] An insulating layer (446) may be disposed between the first light-emitting portion (441) of the light-emitting layer (140) and the second light-emitting portion (442) of the light-emitting layer (140). For example, the insulating layer (446) may be disposed below the second electrode layer (150) and between the first light-emitting portion (441) and the second light-emitting portion (442). Additionally, for example, the insulating layer (446) may be disposed on the first electrode layer (130). The insulating layer (446) may be used as a layer (or PDL) for defining the light-emitting portion. For example, the insulating layer (446) may define the first light-emitting portion (441) and the second light-emitting portion (442). Alternatively, for example, the insulating layer (446) may define the edge of the first light-emitting portion (441) (or the outside of the first light-emitting portion (441) including the edge) and the edge of the second light-emitting portion (442) (or the outside of the second light-emitting portion (442) including the edge).

[0051] An insulating layer (447) may be disposed between a first light-emitting portion (441) and a third light-emitting portion (not shown) of a light-emitting layer (140). For example, the insulating layer (447) may be disposed below a second electrode layer (150) and between the first light-emitting portion (441) and the third light-emitting portion. Additionally, for example, the insulating layer (447) may be disposed on the first electrode layer (130). The insulating layer (447) may be used as a layer (or PDL) for defining the light-emitting portions. For example, the insulating layer (447) may define the first light-emitting portion (441) and the third light-emitting portion. Alternatively, for example, the insulating layer (447) may define the edge of the first light-emitting portion (441) (or the outer edge of the first light-emitting portion (441) including the edge) and the edge of the third light-emitting portion (or the outer edge of the third light-emitting portion including the edge).

[0052] In the above example, the insulating layer (446) and the insulating layer (447) are described as being disposed between the light-emitting portions, but the present disclosure is not limited thereto. For example, the insulating layer may be disposed between the light-emitting portion and the edge of the display panel (100) (or the support member (165) of FIG. 3). The insulating layer may define the edge of the light-emitting portion and the edge of the display panel (100) (or the support member (165) of FIG. 3).

[0053] A second electrode layer (150) may be disposed on the light-emitting portions (441, 442) and insulating layers (446, 447) of the light-emitting layer (140). For example, the second electrode layer (150) may include a first portion (451) disposed on the first light-emitting portion (441), a second portion (452) disposed on the second light-emitting portion (442), and a third portion (453) between the first portion (451) and the second portion (452). For example, the third portion (453) may be disposed on an insulating layer (446) disposed between the first light-emitting portion (441) and the second light-emitting portion (442). In the above example, the second electrode layer (150) is described as including the first portion (451), the second portion (452), and the third portion (453), but the present disclosure is not limited thereto. For example, the second electrode layer (150) may include a portion disposed on the insulating layer (447).

[0054] The second electrode layer (150) may include a protrusion (457). The protrusion (457) may be an example of the protrusion (352) of FIG. 3. For example, the protrusion (457) may form a protruding pattern. As an example without limitation, lines (or bands) extending from the protrusion (457) may form a protruding pattern. For example, a third portion (453) of the second electrode layer (150) may include a protrusion (457). For example, the third portion (453) may include a base (455) and a protrusion (457) protruding (or extending) from the base (455). For example, since the protrusion (457) is formed on a third part (453) disposed on an insulating layer (446) between the light-emitting parts (441, 442), it can minimize the effect on the light emitted by the light-emitting parts (441, 442) (or not affect the light emitted from the light-emitting parts (441, 442).

[0055] For example, as the protrusion (457) protrudes from the base (455), the thickness (459-2) between the distal end (457a) of the protrusion (457) and one side (453a) of the third part (453) may be longer (or thicker) than the thickness (459-1) of the base (455). For example, the thickness (459-1) of the base (455) may represent the thickness from one side (453a) of the third part (453) (or base (455)) to the other side of the base (455). For example, the other side may be a side opposite to the one side (453a). As a non-limiting example, the distal end (457a) may include the top surface of the protrusion (457). However, the present disclosure is not limited thereto. For example, the end (457a) may represent an area including the upper surface of the protrusion (457).

[0056] For example, the protrusion (457) may be inclined (or diagonal) with respect to the base (455). For example, the angle (456) between the protrusion (457) and the base (455) may be lower than a reference angle (e.g., right angle). In other words, the angle (456) may be an acute angle. Referring to FIG. 4, the protrusion (457) may be inclined with respect to the base (455) toward the first light-emitting part (441). However, the present disclosure is not limited thereto. For example, the protrusion (457) may be inclined (or diagonal) toward the center position (e.g., position (315)) of the protrusion pattern (e.g., the protrusion pattern (310) of FIG. 3) in which the protrusion (457) is included. Alternatively, for example, the protrusion (457) may be inclined (or diagonal) in a direction opposite to the direction toward the edge of the display panel (100) (e.g., the side portion (205) of FIG. 2). In other words, the protrusion (457) may be inclined (or diagonal) in a direction to hinder the movement (or flow) of the filling material before the filling material to be formed into the encapsulation layer (470) is cured.

[0057] In the example of FIG. 4, the protrusion (457) is illustrated as having a quadrilateral shape (e.g., square or rectangle) (or, in the case of a three-dimensional structure, a rectangular prism) when viewed from the side of the stacked structure, but the present disclosure is not limited thereto. For example, the protrusion (457) may have a shape having curvature at the end (457a) (or the end (457a) may be formed as a curve). Or, for example, the protrusion (457) may have a polygonal shape (e.g., triangle, pentagon).

[0058] Referring to the above description, the thickness (or size, length) of the protrusion (457), the direction in which the protrusion (457) is inclined, the size of the angle (456) in which the protrusion (457) is inclined, the shape of the protrusion (457), or the location of the protrusion (457) (e.g., location within the third part (453)) may be modified (or formed) to hinder the movement (or flow) of the filling material. Additionally, the number of protrusion patterns (e.g., the protrusion pattern (310) of FIG. 3) formed by the protrusion (457), the number of lines included within the protrusion pattern, the spacing between lines within the protrusion pattern, the spacing between protrusion patterns, the shape of the protrusion pattern, and the location of the protrusion pattern may also be modified (or formed) to hinder the movement (or flow) of the filling material. In one example, the location of the protrusion pattern (or the location of the protrusion (457)) may be related to the location where the filling material is to be applied. As a non-limiting example, if the location of the protrusion pattern (or the location of the protrusion (457)) is the center location of the protrusion pattern (e.g., the location (315) in FIG. 3), the center location of the protrusion pattern may be adjacent to (or coincide with) the location where the filling material is to be applied.

[0059] Although not illustrated in FIG. 4, the thickness of each of the first part (451) and the second part (452) of the second electrode layer (150) may correspond (or be the same as) the thickness (459-1) of the base (455) of the third part (453) of the second electrode layer (150). In other words, the thickness of a part of the second electrode layer (150) may correspond to the thickness (459-1), and the thickness of the remaining part of the second electrode layer (150) (or the area where the protrusion (457) is formed) may correspond to the thickness (459-2).

[0060] Referring to FIG. 4, the encapsulation layer (470) can cover the second electrode layer (150). For example, the filling material forming the encapsulation layer (470) can be filled along the exterior of the second electrode layer (150). For example, the exterior may include the top surface of the second electrode layer (150). For example, the top surface may partially protrude along the protrusion (457).

[0061] The display panel (100) may include a filter layer (480) disposed on an encapsulation layer (470). For example, the filter layer (480) may include filter portions (481, 482) and BM (black matrix) portions (486, 487). For example, the filter portions (481, 482) may be referred to as light-transmitting portions. For example, the filter portions (481, 482) may include a filter structure that passes light of a color corresponding to the color of light emitted from light-emitting portions (441, 442) corresponding to the filter portions (481, 482). At this time, the filter portions (481, 482) may block light having a color other than the corresponding color light. For example, the first filter portion (481) may be disposed on the first light-emitting portion (441). For example, a second filter portion (482) may be disposed on a second light-emitting portion (442). In the present disclosure, the filter portion may be referred to as a light-transmitting portion. For example, BM portions (486, 487) may define the filter portions (481, 482). For example, the BM portions (486, 487) may correspond to insulating layers (446, 447). For example, the first BM portion (486) may be disposed on an insulating layer (446). For example, the second BM portion (487) may be disposed on an insulating layer (447). In the present disclosure, the BM portion may be referred to as light-blocking portions. In FIG. 4, the area (or length) of the filter portion is shown to correspond (or be the same as) the area (or length) of the light-emitting portion, and the area (or length) of the BM portion corresponds (or is the same as) the area (or length) of the insulating layer, but the present disclosure is not limited thereto. As a non-limiting example, the area of ​​the filter portion may be larger than the area of ​​the light-emitting portion, and the area of ​​the BM portion may be smaller than the area of ​​the insulating layer.

[0062] The first light-emitting portion (441) and the second light-emitting portion (442) may correspond to pixels (or subpixels) included in the display panel (100). Referring to example (491), the first light-emitting portion (441) may be included in a first pixel (491a) comprising a first subpixel for a first color (e.g., red color), a second subpixel for a second color (e.g., green color), and a third subpixel for a third color (e.g., blue color), and the second light-emitting portion (442) may be included in a second pixel (491b) comprising a fourth subpixel for the first color, a fifth subpixel for the second color, and a sixth subpixel for the third color. Accordingly, the protrusion (457) and the base (455) may be formed on an insulating layer (491c) between the pixels (491a, 491b). In other words, a third portion (453) of the second electrode layer (150), including a protrusion (457) and a base (455), may be disposed on an insulating layer (491c). Alternatively, referring to example (492), a first light-emitting portion (441) may be included in a first subpixel (492a) for a first color (e.g., red color) (or a third subpixel for a third color (e.g., blue color), and a second light-emitting portion (442) may be included in a second subpixel (492b) for the second color (e.g., green color). Accordingly, the protrusion (457) and the base (455) may be formed on an insulating layer (492c) between the subpixels (492a, 492b) (or the third subpixel and the second subpixel (492b)). In other words, the third portion (453) of the second electrode layer (150), including the protrusion (457) and the base (455), may be disposed on the insulating layer (492c). In the example of FIG. 4, for convenience of explanation, a case in which one pixel includes three subpixels is illustrated, but the present disclosure is not limited thereto.For example, a single pixel may contain two subpixels (e.g., RG / BG), four subpixels (e.g., RGBG), or five or more subpixels.

[0063] Referring to FIG. 4, the display panel (100) can control the movement (or flow) of a filling material by utilizing a second electrode layer (150) that includes a protrusion (457). Accordingly, by delaying contact between the filling material and a support member of the display panel (100) (e.g., the support member (165) of FIG. 3), cracks caused by the support member can be reduced (or prevented). In other words, delamination of the display panel (100) can be prevented. As a structure for controlling the movement (or flow) of the filling material as described above, the second electrode layer (150) may include a dam as well as a protrusion (457). Specific details regarding the second electrode layer (150) including the dam are illustrated and explained below with reference to FIG. 5.

[0064] FIG. 5 illustrates an example of a stacked structure of a display panel including an electrode layer including a protrusion and a dam.

[0065] FIG. 5 illustrates an example of a stacked structure of a display panel (100) including a second electrode layer (150) comprising a protrusion (352) of FIG. 3 (or a protrusion (457) of FIG. 4) and a dam (557). The layers included in the stacked structure of the display panel (100) of FIG. 5 may correspond to the layers included in the stacked structure of the display panel (100) of FIG. 3 or FIG. 4. In other words, the specific details regarding the layers of the stacked structure of the display panel (100) of FIG. 5 may substantially apply to the details regarding the layers of the stacked structure of the display panel (100) of FIG. 3 or FIG. 4. For example, the second electrode layer (150) may include protrusion patterns (310, 320). Example (501) illustrates an example of the second electrode layer (150) in the xz plane when the second electrode layer (150) is viewed from the y-axis direction. Example (502) illustrates an example of a stacked structure of a display panel (100) when the display panel (100) is cut along AA' parallel to the xy plane and viewed in the z-axis direction.

[0066] Referring to the example (501) of FIG. 5, the second electrode layer (150) may include a dam (557) between the protrusion pattern (310) and the protrusion pattern (320). In the present disclosure, the dam may be referred to as another protrusion. For example, the dam (557) may be used to obstruct the movement (or flow) of the charge material. The dam (557) may be a structure that additionally (or secondarily) obstructs the movement (or flow) of the charge material. For example, the dam (557) may be included in the second electrode layer (150) between a specific protrusion pattern and a protrusion pattern adjacent to said specific protrusion pattern. The structure of the second electrode layer (150) including the dam (557) is illustrated through an example (502) of a stacked structure of a display panel (100) cut along AA'.

[0067] Referring to Example (502), the display panel (100) may include a first electrode layer (130), a light-emitting layer (140), a second electrode layer (150), an encapsulation layer (470), and a filter layer (480). In FIG. 5, for convenience of explanation, the display panel (100) is shown not to include a glass substrate (110) and a TFT layer (120), but the present disclosure is not limited thereto. For example, the TFT layer (120) may be placed below the first electrode layer (130) of FIG. 5. For example, the glass substrate (110) may be placed below the TFT layer (120). Additionally, the encapsulation layer (470) of FIG. 5 may include the encapsulation layer (160) of FIG. 3, a support member (165), and a filling material (170). For example, after the curing of the support member (165) and the filling material (170) is completed, the bag layer (470) may include (or be referred to as) one or more layers comprising the bag layer (160), the support member (165), and the filling material (170) of FIG. 3.

[0068] A light-emitting layer (140) may be disposed on a first electrode layer (130). For example, the light-emitting layer (140) may include a first light-emitting portion (541) and a second light-emitting portion (542). For example, the light-emitting portions (541, 442) may include an organic material that emits light of a color according to a subpixel. The first light-emitting portion (541) may be spaced apart from the second light-emitting portion (542). For example, an insulating layer (546) may be disposed between the first light-emitting portion (541) and the second light-emitting portion (542). In the above example, the light-emitting layer (140) is described as a layer distinct from the insulating layer (546), but the present disclosure is not limited thereto. For example, the light-emitting layer (140) may be a layer comprising the insulating layer (546) (or an insulating portion).

[0069] An insulating layer (546) may be disposed between the first light-emitting portion (541) of the light-emitting layer (140) and the second light-emitting portion (542) of the light-emitting layer (140). For example, the insulating layer (546) may be disposed below the second electrode layer (150) and between the first light-emitting portion (541) and the second light-emitting portion (542). Additionally, for example, the insulating layer (546) may be disposed on the first electrode layer (130). The insulating layer (546) may be used as a layer (or PDL) for defining the light-emitting portion. For example, the insulating layer (546) may define the first light-emitting portion (541) and the second light-emitting portion (542). Alternatively, for example, the insulating layer (546) may define the edge of the first light-emitting portion (541) (or the outer edge of the first light-emitting portion (541) including the edge) and the edge of the second light-emitting portion (542) (or the outer edge of the second light-emitting portion (542) including the edge).

[0070] An insulating layer (547) may be disposed between a first light-emitting portion (541) and a third light-emitting portion (not shown) of a light-emitting layer (140). For example, the insulating layer (547) may be disposed below a second electrode layer (150) and between the first light-emitting portion (541) and the third light-emitting portion. Additionally, for example, the insulating layer (547) may be disposed on the first electrode layer (130). The insulating layer (547) may be used as a layer (or PDL) for defining the light-emitting portions. For example, the insulating layer (547) may define the first light-emitting portion (541) and the third light-emitting portion. Alternatively, for example, the insulating layer (547) may define the edge of the first light-emitting portion (541) (or the outer edge of the first light-emitting portion (541) including the edge) and the edge of the third light-emitting portion (or the outer edge of the third light-emitting portion including the edge).

[0071] An insulating layer (548) may be disposed between the second light-emitting portion (542) and the fourth light-emitting portion (not shown) of the light-emitting layer (140). For example, the insulating layer (548) may be disposed below the second electrode layer (150) and between the second light-emitting portion (542) and the fourth light-emitting portion. Additionally, for example, the insulating layer (548) may be disposed on the first electrode layer (130). The insulating layer (548) may be used as a layer (or PDL) for defining the light-emitting portions. For example, the insulating layer (548) may define the second light-emitting portion (542) and the fourth light-emitting portion. Alternatively, for example, the insulating layer (548) may define the edge of the second light-emitting portion (542) (or the outer edge of the second light-emitting portion (542) including the edge) and the edge of the fourth light-emitting portion (or the outer edge of the fourth light-emitting portion including the edge).

[0072] In the example of FIG. 5, the insulating layer (546) may be an insulating layer located between the area of ​​the second electrode layer (150) where the protruding pattern (310) is formed and another area of ​​the second electrode layer (150) where the protruding pattern (320) is formed. For example, the first light-emitting portion (541) may be included in the light-emitting portions within the light-emitting layer (140) defined by the area of ​​the second electrode layer (150) where the protruding pattern (310) is formed. The light-emitting portions within the light-emitting layer (140) defined by the area of ​​the second electrode layer (150) where the protruding pattern (310) is formed may be included in the first set of pixels. Additionally, for example, the second light-emitting portion (542) may be included in the light-emitting portions within the light-emitting layer (140) defined by the other area of ​​the second electrode layer (150) where the protruding pattern (320) is formed. The light-emitting portions within the light-emitting layer (140), defined by the other region of the second electrode layer (150) where the protruding pattern (320) is formed, may be included in a second set of pixels. For example, the second set of pixels may be pixels adjacent to the first set of pixels among the pixels included in the display panel (100). In other words, the insulating layer (546) may be an insulating layer defining one pixel of the first set of pixels (or a pixel including the first light-emitting portion (541)) and one pixel of the second set of pixels (or a pixel including the second light-emitting portion (542)).

[0073] A second electrode layer (150) may be disposed on the light-emitting portions (541, 542) and insulating layers (546, 547) of the light-emitting layer (140). For example, the second electrode layer (150) may include a first portion (551) disposed on the first light-emitting portion (541), a second portion (552) disposed on the second light-emitting portion (542), and a third portion (553) between the first portion (551) and the second portion (552). For example, the third portion (553) may be disposed on an insulating layer (546) disposed between the first light-emitting portion (541) and the second light-emitting portion (542). In the above example, the second electrode layer (150) is described as including the first portion (551), the second portion (552), and the third portion (553), but the present disclosure is not limited thereto. For example, the second electrode layer (150) may include a portion disposed on the insulating layer (547). Additionally, for example, the second electrode layer (150) may include a portion disposed on the insulating layer (548).

[0074] The second electrode layer (150) may include protrusions (457-1, 457-2). Each of the protrusions (457-1, 457-2) may be an example of the protrusion (457) of FIG. 4. The specific details for each of the protrusions (457-1, 457-2) may be substantially the same as those for the protrusion (457) of FIG. 4.

[0075] The second electrode layer (150) may include a dam (557). For example, a third portion (553) of the second electrode layer (150) may include a dam (557). For example, the third portion (553) may include a base (555) and a dam (557) protruding (or extended) from the base (555).

[0076] For example, as the dam (557) protrudes from the base (555), the thickness (559-2) between the distal end (557a) of the dam (557) and one side (553a) of the third part (553) may be longer (or thicker) than the thickness (559-1) of the base (555). For example, the thickness (559-1) of the base (555) may represent the thickness from one side (553a) of the third part (553) (or base (555)) to the other side of the base (555). For example, the other side may be a side opposite to the one side (553a). As a non-limiting example, the distal end (557a) may include the top surface of the dam (557). However, the present disclosure is not limited thereto. For example, the end (557a) may represent an area including the upper surface of the dam (557).

[0077] For example, the dam (557) may be perpendicular to the base (555). For example, the angle (556) between the dam (557) and the base (555) may correspond to a reference angle (e.g., a right angle). In other words, the angle (556) may be a right angle. Referring to FIG. 5, the dam (557) may be perpendicular to the base (555), unlike the protrusions (457-1, 457-2). In FIG. 5, for convenience of explanation, the thickness (or height) between the base (555) and the end (557a) of the dam (557) is depicted as being longer (or thicker) than the thickness (or height) between the base where the protrusion (457-1) (or protrusion (457-2)) extends and the end of the protrusion (457-1), but the present disclosure is not limited thereto. For example, the thickness (or height) between the base (555) and the end (557a) of the dam (557) may be equal to or lower than the thickness (or height) between the base and the end of the protrusion (457-1) (or protrusion (457-2)) where the protrusion extends.

[0078] In the example of FIG. 5, the dam (557) is illustrated as having a quadrilateral shape (e.g., square or rectangle) (or, in the case of a three-dimensional structure, a rectangular prism) when viewed from the side of the stacked structure, but the present disclosure is not limited thereto. For example, the dam (557) may have a shape having curvature at the end (557a) (or the end (557a) is formed as a curve). Or, for example, the dam (557) may have a polygonal shape (e.g., triangle, pentagon).

[0079] Referring to the above, the thickness (or size, length) of the dam (557), the shape of the dam (557), the location of the dam (557) (e.g., location within the third part (553) or distance from the protruding pattern), and the number of dams (557) may be changed (or formed) to hinder the movement (or flow) of the filling material. In one example, the location of the dam (557) may be related to the location where the filling material is to be applied.

[0080] Figure 6 illustrates an example of a protruding pattern formed on an electrode layer.

[0081] FIG. 6 illustrates an example of a second electrode layer (150) including protruding patterns (610, 620). For example, FIG. 6 illustrates an example of the second electrode layer (150) in the xz plane when viewed from the y-axis direction.

[0082] For example, the second electrode layer (150) may include protruding patterns (610, 620). For example, a protruding pattern (610) may be formed on the second electrode layer (150) centered at a location (615). For example, a protruding pattern (620) may be formed on the second electrode layer (150) centered at a location (625). For example, the location (615) may represent the center of the protruding pattern (610). As an example without limitation, the location (615) may be a location of the light-emitting portion of the light-emitting layer (140) or an insulating layer (or insulating portion). For example, the location (625) may represent the center of the protruding pattern (620). As an example without limitation, the location (625) may be a location of the light-emitting portion of the light-emitting layer (140) or an insulating layer (or insulating portion). For example, the protrusion pattern (610) (or, protrusion pattern (620)) may have a concentric object shape with respect to a position (615) (or,, position (625)). Unlike the protrusion patterns (310, 320) of FIG. 3, the concentric object shape of the protrusion pattern (610) may be a concentric circle. In the example of FIG. 6, the concentric circle is exemplified as the concentric object shape, but the present disclosure is not limited thereto.

For example, the dam (757) may be placed on an insulating layer positioned below the side portion of the display panel (100). The insulating layer may be positioned below the second electrode layer (150) and may be positioned to define the side portion of the display panel (100).
