[0038] Various embodiments will be described below with reference to the accompanying drawings.

[0039] The same reference numerals denote the same parts. Furthermore, in the accompanying drawings, the thickness, scale, and dimensions of parts may be exaggerated to effectively describe the technical content. For ease of explanation, the scale of the parts shown in the drawings differs from the actual scale, and therefore, the drawings are not limited to the scales shown.

[0040] In this specification, when a component (or area, layer, section, etc.) is described as "on another component", "connected to", or "attached to" another component, it means that the component can be directly connected to / attached to the other component, or that the other component can be positioned between them.

[0041] The term "and / or" includes all or one combination that can be defined by the associated configuration.

[0042] Terms such as "first," "second," etc., may be used to describe various components, but these components are not limited by these terms. These terms are used only for the purpose of distinguishing one component from another. For example, without departing from the scope of the various embodiments, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component. The singular includes the plural unless the context clearly specifies otherwise.

[0043] Terms such as “below,” “under,” “above,” and “on top” are used to describe the relationships between the components shown in the accompanying drawings. These terms are relative concepts and are described relative to the directions marked in the drawings. For example, one or more other parts may be located between two parts, provided that “immediately following” or “directly” is not used. Spatially relative terms such as “below or below,” “lower,” “above,” “upper,” etc., can be used to readily describe the relationship between one element or component and another element or component, as shown in the accompanying drawings. Spatially relative terms should be understood to include, in addition to the directions shown in the accompanying drawings, different orientations of the elements in use or operation. For example, in the case where the elements shown in the accompanying drawings are flipped upside down, an element described as being positioned “below” or “under” another element may be positioned “above” another element. Thus, the exemplary term “below” can include both downward and upward directions.

[0044] It should be understood that terms such as “comprising” or “having” are intended to specify the presence of features, figures, steps, operations, components, parts or combinations thereof described in the specification, without precluding the possibility of the presence or addition of one or more other features, figures, steps, operations, components, parts or combinations thereof.

[0045] Features of the various embodiments in this specification can be joined or combined in part or in whole to enable various technologies to interoperate and drive, and the various embodiments can be implemented independently of each other or together in an associated relationship.

[0046] Any implementation described as an "example" in this document is not necessarily to be construed as preferred or superior to other implementations.

[0047] Furthermore, when referring to any size, relative size, etc., the numerical values ​​or corresponding information of a component or feature (e.g., level, range, etc.) should be considered to include tolerances or error ranges that may be caused by various factors (e.g., process factors, internal or external influences, noise, etc.), even if no relevant description is specified. Additionally, the term "may" fully encompasses all the meanings of the term "able to".

[0048] When describing temporal relationships, discontinuous cases may be included if the temporal order is described as such as “after,” “following,” “next,” and “before,” unless more restrictive terms such as “just,” “immediately,” or “directly” are used.

[0049] The term “at least one” should be understood to include any and all combinations of one or more of the associated listed items. For example, “at least one of the first element, the second element, and the third element” means a combination of all three listed elements, a combination of any two of the three elements, and each individual element, the first element, the second element, or the third element.

[0050] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the example embodiments pertain. It should also be understood that terms (such as those defined in common dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant field and should not be interpreted in an idealized or overly formal sense unless explicitly defined herein. For example, the terms “part” or “unit” can be applied to, for example, a single circuit or structure, an integrated circuit, a computational block of a circuit arrangement, or any structure configured to perform the functions described herein as would be understood by one of ordinary skill in the art.

[0051] As will be fully understood by those skilled in the art, the features of the various embodiments of this disclosure can be joined or combined in part or in whole, and can interoperate and be technology-driven in various ways. The embodiments of this disclosure can be performed independently of each other, or can be performed together in a cascading relationship.

[0052] The display device described herein will be described below with reference to the accompanying drawings and embodiments.

[0053] Figure 1 This is a plan view of a display device according to one embodiment.

The display panel 100 may include: a display area DA, which includes a plurality of pixels PX; and a non-display area NDA, which surrounds the display area DA. The flat surface shape of the display area DA may be rectangular. However, the various embodiments of this specification are not limited thereto, and the flat surface shape of the display area DA may be square, circular, elliptical, or other polygonal shapes. For example, the display area DA may have a rectangular shape with rounded corners, but is not limited thereto, and may also have a rectangular shape with beveled corners.

[0055] In various embodiments, the first direction DR1 and the second direction DR2 are different directions and intersect each other, for example, perpendicularly intersecting directions in a plan view. Figure 1 In this embodiment, the first direction DR1 can typically be the same as the extension direction of the short side of the display panel 100, while the second direction DR2 can be the same as the extension direction of the long side of the display panel 100. However, the directions described in the various embodiments should be understood as indicating relative directions, and the various embodiments are not limited to the described directions.

[0056] The display area DA may include a short side extending in the first direction DR1 and a long side extending in the second direction DR2. The non-display area NDA may surround the display area DA. The non-display area NDA may be disposed on one side and the other side of the display area DA along the first direction DR1 and along the second direction DR2.

In a plan view, sensor holes SH1 and SH2 may be surrounded by the display area NDA_S. Sensor holes SH1 and SH2 may be, for example... Figure 1The two sensor holes in the display area DA are not limited to this, but various embodiments of the present specification are not limited to this. For example, the sensor holes can be configured as a single sensor hole. The two sensor holes SH1 and SH2 can each include a sensor hole in which an infrared sensor is disposed and a sensor hole in which a camera sensor is disposed, but various embodiments of the present specification are not limited to this. The sensor non-display area NDA_S can be disposed between the sensor holes SH1 and SH2 and the display area DA. The sensor non-display area NDA_S can completely surround the sensor holes SH1 and SH2. Pixels PX can be not disposed in the sensor non-display area NDA_S. In some embodiments, sensor holes SH1 and SH2 are not disposed, and the infrared sensor or camera sensor can be disposed in the display area DA. In this case, the number of pixels PX per unit area of ​​the display area DA in which the infrared sensor or camera sensor is disposed can be less than the number of pixels PX per unit area of ​​the display area DA in which the infrared sensor or camera sensor is not disposed. That is, the display area DA in which the infrared sensor or camera sensor is disposed can further include a transmission area.

[0058] The gate drive unit (GIP) can be disposed in the non-display area NDA, located on one side and the other side of the display area DA along the first direction DR1.

[0059] The non-display area NDA located on the other side of the display area DA in the second direction DR2 can further extend from the center portion of the other side toward the other side of the display area DA in the second direction DR2. The width of the non-display area NDA extending further from the center portion of the display area DA on the other side of the second direction DR2 toward the other side of the second direction DR2 in the first direction can be smaller than the width of the non-display area NDA adjacent to the other side of the display area DA in the second direction DR2 in the first direction DR1.

[0060] Display device 1 may include a main region MR, a sub-region SR, and a curved region BR between the main region MR and the sub-region SR. A display region DA and a non-display region NDA surrounding the four surfaces of the display region DA may form the main region MR, and a portion extending from the center of the display region DA on the other side of the second direction DR2 may form the curved region BR and the sub-region SR. The curved region BR may be disposed between the sub-region SR and the main region MR. The sub-region SR may include a first pad region PA1 and a second pad region PA2, the first pad region PA1 and the second pad region PA2 being located at the ends of the sub-region SR on the other side of the second direction DR2. Display device 1 may also include a data driver unit DIC and a printed circuit board FPCB. The data driver unit DIC may be disposed in the first pad region PA1, and the printed circuit board FPCB may be attached to the second pad region PA2. A plurality of pads connected to the data driver unit DIC and the printed circuit board FPCB may be disposed in each of the first pad region PA1 and the second pad region PA2. The data driver unit DIC may be configured, for example, in the form of a driver chip (IC), but is not limited thereto. In one embodiment, a method is described in which the data driving unit DIC is set by directly mounting a plastic chip onto the display panel 100. However, various embodiments of this specification are not limited to this, and the data driving unit DIC can be set by a glass chip or a thin-film chip method.

[0061] According to one embodiment, the display panel 100 may further include a crack sensing pattern CSP surrounding a low-potential voltage line VSSL. The crack sensing pattern CSP may be configured to completely surround the display area DA, such as... Figure 1 As shown. For example, the crack sensing pattern CSP can be disposed outside the low-potential voltage line VSSL. However, various embodiments of this specification are not limited thereto, and a portion of the crack sensing pattern CSP may not be disposed in the non-display area NDA on the other side of the display area DA in the second direction DR2.

[0062] In some embodiments, the display panel 100 may be a foldable display panel for use in foldable products. In this case, it can be based on... Figure 1 A folding axis is formed extending in either a first direction DR1 or a second direction DR2. The folding axis may be formed to extend across the display area DA and the non-display area NDA. The foldable display panel can be folded around the folding axis.

[0063] Figure 2 It shows the basis Figure 1 A cross-sectional view of the curved state of the display panel.

[0064] Reference Figure 2 According to one embodiment, the curved region BR of the display panel 100 of the display device 1 can be bent in the thickness direction (or the third direction DR3). Therefore, the main region MR and the sub-region SR can overlap each other in the thickness direction. The display panel 100 can be bent such that the lower surface of the main region MR faces the upper surface of the sub-region SR. A printed circuit board FPCB can be attached to the end of the sub-region SR.

(Refer to...) Figure 4 Describe the touch portion 180.

[0118] Figure 4 It is based on Figure 3 A cross-sectional view of the touch portion.

[0119] Reference Figure 3 and Figure 4 The touch buffer layer 181 may be disposed on the encapsulation portion 170. For example, the touch buffer layer 181 may be disposed on the third encapsulation layer 173. The touch buffer layer 181 may be made of the same material as the buffer layer 102, but various embodiments of this specification are not limited thereto.

[0120] A first touch conductive layer may be disposed on the touch buffer layer 181. The first touch conductive layer may include a bridge electrode 182.

The bridge electrode 182 and sensor electrode 184 may overlap with the black matrix BM in the thickness direction, as will be described below. The black matrix BM may cover the bridge electrode 182 and sensor electrode 184. Therefore, the visibility of the bridge electrode 182 and sensor electrode 184 from the outside can be prevented or reduced.

[0121] A first touch insulating layer 183 may be disposed on a first touch conductive layer. The first touch insulating layer 183 can prevent short circuits between the first touch conductive layer and the second touch conductive layer.

[0125] The upper insulating layer may be further disposed on the second touch insulating layer 185, but the various embodiments of this specification are not limited thereto.

[0126] Color filters 191, 192, and 193 can be disposed on the second touch insulating layer 185. Color filters 191, 192, and 193 can be disposed on the first to third sub-pixels PX1, PX2, and PX3 respectively, and can block specific colors of light emitted from the light-emitting regions EA1, EA2, and EA3 of sub-pixels PX1, PX2, and PX3. A first color filter 191 can be provided to block light of other colors that do not include red (R) light. In this case, the first color filter 191 can be provided as a red color filter. A second color filter 192 can be provided to block light of other colors that do not include green (G) light. In this case, the second color filter 192 can be provided as a green color filter. A third color filter 193 disposed in the third sub-pixel PX3 can be provided to block light of other colors that do not include blue (B) light. In this case, the third color filter 193 can be provided as a blue color filter. However, the various embodiments described herein are not limited thereto. Color filters 191, 192, and 193 can be disposed on the light-emitting regions EA1, EA2, and EA3, respectively, and can extend into portions of the non-light-emitting regions NEA1, NEA2, and NEA3, but the various embodiments described herein are not limited thereto. Color filters 191, 192, and 193 can be spaced apart from each other at the boundaries between sub-pixels PX1, PX2, and PX3.

[0127] According to various embodiments of this specification, a black matrix BM can be formed after the formation of the first to third color filters 191 to 193.

[0128] According to various embodiments of this specification, the width of the black matrix BM can be smaller than the width of the embankment 154. For example, the separation distance between the black matrix BM located in the first and second non-emitting regions NEA1 and NEA2 and the black matrix BM located in the second and third non-emitting regions NEA2 and NEA3 can be greater than the separation distance between the embankment 154 located in the first and second non-emitting regions NEA1 and NEA2 and the embankment 154 located in the second and third non-emitting regions NEA2 and NEA3. The end of the embankment 154 can be aligned with the boundary between the emitting regions EA1, EA2, and EA3 and the non-emitting regions NEA1, NEA2, and NEA3, but various embodiments of this specification are not limited thereto. In the case of the display panel 100 according to one embodiment, since the embankment 154 may include a black-based material and the width of the black matrix BM is smaller than the width of the embankment 154, light emitted from the emitting regions EA1, EA2, and EA3 can be emitted upward at a viewing angle greater than the opening exposed by the black matrix BM. Therefore, a decrease in brightness according to the viewing angle can be prevented. However, when the width of the black matrix BM is smaller than the width of the dam 154 and the dam 154 is made of only transparent material, external incident light can be reflected by the dam 154, resulting in a perceived ring artifact. However, in the display panel 100 according to one embodiment, external incident light can be absorbed or blocked by the dam 154, which includes a black-based material, thereby preventing or reducing the occurrence of ring artifacts and preventing or reducing external light reflection (or surface reflection).

[0129] For example, the black matrix BM can be located at the boundary between the second sub-pixel PX2 and the third sub-pixel PX3, and at the boundary between the third sub-pixel PX3 and the first sub-pixel PX1. The black matrix BM may not be located at the boundary between the first sub-pixel PX1 and the second sub-pixel PX2. The island pattern BP can be located at the boundary between the first sub-pixel PX1 and the second sub-pixel PX2. The island pattern BP can include the same material as the third color filter 193. That is, the island pattern BP can transmit blue light and block red and green light. According to one embodiment, by omitting the black matrix BM and setting the blue-transmitting island pattern BP at the boundary between the first sub-pixel PX1 and the second sub-pixel PX2, the overall blue reproduction can be enhanced. Furthermore, at the boundary between the first sub-pixel PX1 and the second sub-pixel PX2, from left to right, a first color filter 191 that transmits only red light, an island pattern BP, and a second color filter 192 that transmits only green light are sequentially arranged, such that the island pattern BP and the surrounding color filters 191 and 192 can perform the function of the black matrix BM.

[0130] According to this embodiment, since the black matrix BM is formed after the color filters 191, 192, and 193 are formed, the black matrix BM can have an inverted cone shape. Furthermore, for example, a first color filter 191 can be formed, a second color filter 192 can be formed, and then a third color filter 193 can be formed, and the island pattern BP can be formed together with the third color filter 193. Therefore, the island pattern BP can also have an inverted cone shape.

[0131] The black matrix BM can directly contact the side surface of the organic layer 152 disposed in the adjacent second and third sub-pixels PX2 and PX3, as well as the side surface of the organic layer 152 disposed in the adjacent third and first sub-pixels PX3 and PX1.

[0132] The island pattern BP can be in direct contact with the side surface of the organic layer 152 disposed in the adjacent first and second sub-pixels PX1 and PX2.

[0133] In a display device 1 according to one embodiment, since a black matrix BM is formed after the color filters 191, 192, and 193 are formed, steps between the color filters 191, 192, and 193 in the non-light-emitting areas NEA1, NEA2, and NEA3 due to the existing black matrix can be prevented or reduced. When steps occur between the color filters 191, 192, and 193, external light can be diffracted or reflected at the steps, making it visible from the outside. However, in the display device 1 according to one embodiment, since this step does not occur, image quality can be improved.

[0134] Figure 3 The diagram shows that the black matrix BM and the island pattern BP do not overlap with the upper surfaces of adjacent color filters 191, 192, and 193 and only contact their side surfaces; however, various embodiments of this specification are not limited thereto. For example, the black matrix BM and the island pattern BP may be configured to extend to portions of the upper surfaces of adjacent color filters 191, 192, and 193.

[0135] in addition, Figure 3 The cross-sectional shape of the black matrix BM and the island pattern BP is shown to be an inverted conical trapezoid, but various embodiments of this specification are not limited to this, and the cross-sectional shape may also be a shape with a concave center (e.g., V-shaped or U-shaped).

[0136] Furthermore, since the black matrix BM is formed after the color filters 191, 192 and 193 are formed, the area of ​​the black matrix BM can be intentionally reduced, and the area of ​​the opening region (or the light-emitting regions EA1, EA2 and EA3) can be increased.

[0137] In addition, the viewing angle can be increased by reducing the area of ​​the black matrix BM.

[0138] In addition, as mentioned above, by designing the width of the black matrix BM to be smaller than the width of the embankment 154, the viewing angle can be increased.

[0139] Planarization layer 200 may be disposed on color filters 191, 192, and 193, the black matrix BM, and the island pattern BP. Planarization layer 200 may include an organic insulating material, but is not limited to the various embodiments described herein. Planarization layer 200 may be in direct contact with color filters 191, 192, and 193, the black matrix BM, and the island pattern BP.

[0140] The upper insulating layer 210 may be disposed on the planarization layer 200. The upper insulating layer 210 may include an organic insulating material, but the various embodiments described herein are not limited thereto.

[0141] Cover layer 300 may be disposed on upper insulating layer 210. Cover layer 300 may include glass or plastic, but various embodiments of this specification are not limited thereto. Cover layer 300 may protect display panel 100.

[0142] An adhesive layer 220 may be disposed between the cover layer 300 and the display panel 100 (or the upper insulating layer 210). The adhesive layer 220 may include, for example, an adhesive material having a gray-based color. For example, the adhesive layer 220 may be formed by mixing a gray-based color material with an optically clear adhesive (OCA), but various embodiments of this specification are not limited thereto. According to one embodiment, by disposing an adhesive layer 220 having a gray-based color between the cover layer 300 and the display panel 100, external light entering the display panel 100 can be partially reduced.

That is, at least one of the inorganic layers 102, 103, 104, 105-1, 105-2, 106, 108, and 109 of the panel may expose the end of the substrate 101, but the various embodiments of this specification are not limited thereto.

Figure 3 The conductive layer on the same layer or located on the same layer as the second light-shielding layer 136 (see...) Figure 3 The conductive layer is formed on the same layer as the first source electrode 121, but various embodiments of this specification are not limited thereto. For example, the crack sensing pattern CSP may include a conductive layer located on the same layer as the first source electrode 121, but various embodiments of this specification are not limited thereto.

[0148] A low-potential voltage line VSSL can be disposed between the crack sensing pattern CSP and the gate drive unit GIP.

[0155] In each dam D2 or D3, the embankment 154 may overlap with and completely cover the second protective layer 112 forming the first layer, but various embodiments of this specification are not limited thereto. In the third dam D3, the embankment 154 may contact the side surface of the second protective layer 112 and the upper surface of the substrate 101, but various embodiments of this specification are not limited thereto.

[0156] Spacer 155 may be disposed on dam 154. Spacer 155 may be disposed on the upper surface of dam 154 overlapping with gate drive unit GIP. Spacer 155 may prevent or reduce overflow of the second encapsulation layer 172, which will be described below. Spacer 155 may form a third layer of dams D2 and D3 and a second layer of the first dam D1. Spacer 155 forming the third layer of each of dams D2 and D3 may overlap with and completely cover dam 154 forming the second layer, but various embodiments of this specification are not limited thereto.

Spacer 155 forming the third layer of each of dams D2 and D3 may overlap with and completely cover dam 154 forming the first layer, but various embodiments of this specification are not limited thereto.

[0157] A package portion 170 may be disposed on the spacer 155. A first package layer 171 may extend to the gate drive unit GIP, the low-potential voltage line VSSL, and the first dams D1 to the third dams D3, and cover the outer surface of the third dam D3. As described above, a second package layer 172 may terminate at the spacer 155 within the first dam D1, or terminate at the first dam D1. The second package layer 172 may overlap with the gate drive unit GIP. A third package layer 173 may extend to the gate drive unit GIP, the low-potential voltage line VSSL, and the first dams D1 to the third dams D3, and may directly contact the first package layer 171 on each of the first dams D1 to the third dam D3.

[0160] Meanwhile, in the display panel 100 according to one embodiment, the above references Figure 3The described island pattern BP can be further disposed between the black matrix BM disposed on each of dams D1 and D2 and each of dams D1 and D2. That is, the black matrix BM can be disposed on the upper surface of the island pattern BP on dams D1 and D2. The width of the island pattern BP can be equal to the width of the black matrix BM, but various embodiments of this specification are not limited thereto.

[0161] According to various embodiments of this specification, by setting a third color filter 193 (see [reference]) in the non-display area NDA, Figure 3 Using the same material in an island pattern BP, the heights of dams D1 and D2 can be further increased. For example, as... Figure 5 As shown, an island pattern BP and a black matrix BM are stacked on the first dam D1, thereby increasing the surface height compared to the existing first dam D1. Similarly, an island pattern BP and a black matrix BM are stacked on the second dam D2, thereby increasing the surface height compared to the existing second dam D2.
