[0045] The present disclosure may be embodied in various modified forms, and thus specific embodiments are described in more detail with reference to the drawings. However, the present disclosure should not be construed as limited to these specific embodiments, but rather should be understood to encompass all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure.

[0046] Hereinafter, embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. However, the present disclosure may be implemented in various forms and should not be construed as limited to the embodiments illustrated herein. These embodiments are provided to sufficiently convey the technical concepts and features of the present disclosure to those skilled in the art and are merely examples to enable a complete and thorough understanding of the present disclosure. Accordingly, processes, components, or technical details unnecessary for understanding the technical concepts and features of the present disclosure may be omitted from the description.

[0047] When a component (e.g., a region, layer, film, portion, etc.) is described herein as being “on,” “connected to,” or “coupled to” another component, this means that the component may be directly located, directly connected, or coupled to the other component, or that one or more intervening components may be present. Conversely, when a component is described as being “directly on,” “directly connected to,” “directly coupled to,” or “directly adjacent to,” it means that the component is directly connected or coupled without any intervening components. Furthermore, when a component is described as being “between” two components, that component may be present alone between the two components, or that one or more intervening components may be present between the two components.

[0048] Unless otherwise specified, the same reference numerals in the accompanying drawings and throughout this specification refer to the same or similar components, and their redundant description may be omitted. Furthermore, in the drawings, the relative sizes (e.g., thicknesses, ratios, dimensions, etc.) of components, layers, or regions may be exaggerated to effectively illustrate the technical content of the present disclosure.

[0049] The term “and / or” as used herein means any combination of one or more of the listed items.

[0050] In this specification, terms such as “first,” “second,” and “third” may be used to distinguish various components, parts, regions, layers, and / or portions, but are not intended to limit such components, parts, regions, layers, and / or portions. For example, the first component described below may be referred to as the second component, without departing from the spirit and scope of the present invention.

[0051] As used herein, singular forms such as “a,” “an,” and “the” should be construed to include plural forms as well, unless the context clearly indicates otherwise.

[0052] In this specification, spatial relative terms such as “upper,” “lower,” “lower,” “upper,” “lower,” and “lower” are used for convenience of explanation in the drawings, and are intended to indicate the relationship between one component or feature and other component(s) or feature(s). Therefore, these spatial relative terms may include various directions during actual use or operation of the device, in addition to the directions depicted in the drawings. For example, when the device is used upside down, elements described as “lower” or “lower” in the drawings may actually be “upper” or “upper.” Therefore, these terms used in this specification should be flexibly interpreted according to various orientations of the device.

[0053] Additionally, the terms “comprises,” “comprising,” “includes,” “including,” “have,” “having,” and the like, as used herein, are intended to specify the presence of stated features, integers, steps, operations, components, and / or parts, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, and / or parts and / or combinations thereof. Furthermore, the terms may include or support the meaning of “consisting of” and “consisting essentially of,” which may indicate the absence or essential absence of other elements in the presence of the stated elements.

[0054] Unless otherwise specified herein, when the prepositional phrases “at least one,” “a plurality of,” “an,” etc. are used to precede a plurality of constituents, they should be interpreted to include the meaning of “and” if the conjunction is expressed as “or,” and conversely, the meaning of “or” if the conjunction is expressed as “and.” For example, expressions such as “at least one of a, b, or c,” “at least one of a, b, and / or c,” “one selected from the group consisting of a, b, c,” “at least one of a, b, c,” “at least one of a through c,” “one of a, b, c,” etc., are interpreted to include various combinations such as a only, b only, c only, a and b, a and c, b and c, or all of a, b, and c.

[0055] The terms “use,” “using,” and “used” used in this specification may be considered synonymous with the terms “utilize,” “utilizing,” and “utilized,” respectively.

[0056] Unless otherwise defined in the context of this specification, a plan view means an orthographic projection of a three-dimensional object with respect to a horizontal plane. That is, a plan view is a drawing that shows the arrangement and spatial relationship of various components within an object or structure from a top-down viewpoint. A plan view based on direction DR3 means a plan view based on a direction looking down vertically from above the display panel, wherein direction DR3 is a direction perpendicular to a plane defined by the first direction DR1 and the second direction DR2. In this plan view, the arrangement of subpixels, pads, and other components arranged on the substrate can be confirmed in a planar manner without perspective distortion.

[0057] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. Furthermore, terms defined in commonly used dictionaries should be interpreted to have a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an overly idealistic or overly formal sense unless explicitly defined herein.

[0058] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0059] Fig. 1 is a front view of a display device according to one embodiment of the present invention. Fig. 2 is a perspective view of a display device according to one embodiment of the present invention.

[0060] Referring to FIGS. 1 and 2, the display device (DD) may be a device activated by an electrical signal. The display device (DD) may be applied to electronic devices such as mobile phones, tablets, smart watches, laptops, computers, and smart televisions.

[0061] The display device (DD) can display an image on a display surface (IS) parallel to each of the first direction (DR1) and the second direction (DR2). The display surface (IS) on which the image is displayed can correspond to the front surface of the display device (DD). The image can include a still image as well as a moving image. The normal direction of the display surface (IS), i.e., the thickness direction of the display device (DD), is indicated by a third direction (DR3). The front (or upper surface) and the back (or lower surface) of each of the layers or units described below are distinguished by the third direction (DR3).

[0062] The display surface (IS) of the display device (DD) can be divided into a display area (DA, active area) and a non-display area (NDA, peripheral area). The display area (DA) may be an area where an image is displayed. A user views an image through the display area (DA). In the present embodiment, the display area (DA) is illustrated as a rectangular shape with rounded corners. However, this is merely an example, and the display area (DA) may have various shapes and is not limited to any one embodiment.

[0063] The non-display area (NDA) is adjacent to the display area (DA). The non-display area (NDA) may have a predetermined color. The non-display area (NDA) may surround the display area (DA). Accordingly, the shape of the display area (DA) may be substantially defined by the non-display area (NDA). However, this is merely an example, and the non-display area (NDA) may be arranged adjacent to only one side of the display area (DA) or may be omitted. The display device (DD) according to an embodiment of the present invention may include various embodiments and is not limited to any one embodiment.

[0064] Fig. 1 may be a front view of a display device (DD) operating in a first mode or a second mode. Fig. 2 may be a side perspective view of a display device (DD) operating in a second mode. For example, the first mode may be a normal mode that displays a screen at a first viewing angle, and the second mode may be a private mode that displays a screen at a second viewing angle that is narrower than the first viewing angle. The first viewing angle and the second viewing angle may be defined as angles at which image quality can be viewed without distortion based on the normal direction of the display surface (IS).

[0065] Referring to FIG. 1, in the first mode or the second mode, when the display device (DD) is viewed from the front (or in a direction parallel to the normal direction or in a third direction (DR3)), images (IM) generated in the display device (DD) can be viewed by the user. In the second mode, when the display device (DD) is viewed from an angle exceeding the second viewing angle, the images (IM) may not be viewed.

[0066] The second viewing angle and the brightness at the second viewing angle in the second mode can be set in various ways. When the display device (DD) is viewed at an angle exceeding the second viewing angle in the first mode, the user can recognize the images (IM). For example, the second viewing angle may be 45 degrees, and the brightness at 45 degrees may be 10 percent of the maximum brightness. In the first mode, the brightness at 45 degrees may be 20 percent or more. However, this is not particularly limited.

[0067] The display device (DD) can selectively operate in either a first mode, which displays the screen at a first viewing angle, or a second mode, which displays the screen at a second viewing angle narrower than the first viewing angle. Switching between the first and second modes can be set by the user, or the display can switch from the first mode to the second mode when a specific application is running. For example, when an application with a risk of personal information exposure, such as a banking or memo application, is running, the display device (DD) can switch from the first mode to the second mode.

[0068] Figure 3 is a cross-sectional view of a display device according to one embodiment of the present invention.

[0069] Referring to FIG. 3, the display device (DD) may include a display panel (DP) and a light control layer (300). Although not shown, a window defining an exterior appearance of the display device (DD) may be arranged on the light control layer (300).

[0070] The display panel (DP) may include a display layer (100) and a sensor layer (200).

[0071] The display layer (100) may include a base layer (110), a circuit layer (120), a light-emitting element layer (130), and an encapsulation layer (140). The display layer (100) may be a configuration that substantially generates an image. The display layer (100) may be a light-emitting display layer, and for example, the display layer (100) may be an organic light-emitting display layer, an inorganic light-emitting display layer, an organic-inorganic light-emitting display layer, a quantum dot display layer, a micro LED display layer, or a nano LED display layer.

[0072] The base layer (110) may be a member that provides a base surface on which the circuit layer (120) is placed. The base layer (110) may be a glass substrate, a metal substrate, a silicon substrate, a polymer substrate, or the like. However, the embodiment is not limited thereto, and the base layer (110) may be an inorganic layer, an organic layer, or a composite material layer.

[0073] The circuit layer (120) may be disposed on the base layer (110). The circuit layer (120) may include an insulating layer, a semiconductor pattern, a conductive pattern, and a signal line. The insulating layer, the semiconductor layer, and the conductive layer are formed on the base layer (110) by a coating, deposition, or the like method, and then the insulating layer, the semiconductor layer, and the conductive layer may be selectively patterned through multiple photolithography processes. Thereafter, the semiconductor pattern, the conductive pattern, and the signal line included in the circuit layer (120) may be formed.

[0074] The light-emitting element layer (130) may be disposed on the circuit layer (120). The light-emitting element layer (130) may include a light-emitting element. For example, the light-emitting element layer (130) may include an organic light-emitting material, an inorganic light-emitting material, an organic-inorganic light-emitting material, a quantum dot, a quantum rod, a micro LED, or a nano LED.

[0075] The encapsulating layer (140) may be disposed on the light-emitting element layer (130). The encapsulating layer (140) may protect the light-emitting element layer (130) from foreign substances such as moisture, oxygen, and dust particles. The encapsulating layer (140) may include a plurality of inorganic layers and an organic layer disposed between the inorganic layers.

[0076] The sensor layer (200) can detect external input applied from the outside. The external input may be a user's input. The user's input may include various forms of external input, such as a part of the user's body, light, heat, a pen, or pressure. The sensor layer (200) may be referred to as a sensor, an input detection layer, or an input detection panel. The sensor layer (200) may be formed through a continuous process with the display layer (100) and may be directly disposed on the display layer (100). However, the present invention is not particularly limited thereto. For example, the sensor layer (200) may be bonded to the display layer (100) through an adhesive layer. The adhesive material may include a typical adhesive or pressure-sensitive adhesive.

[0077] The light control layer (300) may be disposed on the sensor layer (200). The light control layer (300) may reduce the reflectivity of external light incident from the outside of the display device (DD). The light control layer (300) may be disposed directly on the sensor layer (200). However, this is not limited thereto, and an adhesive material may be disposed between the light control layer (300) and the sensor layer (200).

[0078] FIG. 4a is a plan view illustrating an enlarged portion of a display area according to one embodiment of the present invention. FIG. 4b is a plan view illustrating an enlarged portion of a display area according to one embodiment of the present invention.

[0079] Referring to FIG. 4A, a first unit pixel (WPX) and a second unit pixel (NPX) may be arranged in the display area (DA). The first unit pixel (WPX) may include pixels having a relatively wide viewing angle, and the second unit pixel (NPX) may include pixels having a relatively narrow viewing angle.

[0080] FIG. 4A shows a portion of the display area (DA), and the remaining areas of the display area (DA) can also be configured to include first unit pixels (WPX) and second unit pixels (NPX) similarly to FIG. 4A.

[0081] According to the present invention, the display area (DA) may be arranged with first areas (A1) and second areas (A2). One first area (A1) may be defined as an area where one first unit pixel (WPX) is arranged, and the second areas (A2) may be defined as an area where second unit pixels (NPX) are arranged. For example, as illustrated in FIG. 4A, one first area (A1) may include one first unit pixel (WPX), and one second area (A2) may include one second unit pixel (NPX).

[0082] A plurality of first areas (A1) and second areas (A2) may be arranged in the display area (DA). The first areas (A1) may be arranged to be spaced apart from each other along a first direction (DR1) and a second direction (DR2). According to one embodiment, an edge of the first areas (A1) may contact an edge of another adjacent first area (A1) along the first direction (DR1) and / or the second direction (DR2). The second areas (A2) may be arranged to be spaced apart from each other along the first direction (DR1) and the second direction (DR2). According to the present invention, the first areas (A1) and the second areas (A2) may be alternately arranged along a first diagonal direction (CDR1) and a second diagonal direction (CDR2). The first and second diagonal directions (CDR1, CDR2) may have an angle inclined with respect to the first direction (DR1) and / or the second direction (DR2), respectively. Each of the first regions (A1) and the second regions (A2) may be defined as a rhombus shape on a plane.

[0083] According to one embodiment, four different second regions (A2) may be arranged adjacent to one first region (A1) in a first diagonal direction (CDR1) and a second diagonal direction (CDR2), and four different first regions (A1) may be arranged adjacent to one second region (A2) in a first diagonal direction (CDR1) and a second diagonal direction (CDR2). Accordingly, another region may be arranged adjacent to one side forming a rhombus shape. For example, one first region (A1) may have four sides forming a generally rhombus shape, and a total of four second regions (A2), one for each side, may be arranged around (e.g., at the periphery) of the first region (A1). In addition, two of the four sides of the first region (A1) may be arranged along the first diagonal direction (CDR1), and the remaining two may be arranged along the second diagonal direction (CDR2).

[0084] Additionally, a second region (A2) may also have four sides that are generally in the shape of a rhombus, and a total of four first regions (A1), one for each side, may be arranged around (e.g., around) the second region (A2). In this case, two of the four sides of the second region (A2) may be arranged along the first diagonal direction (CDR1), and the remaining two may be arranged along the second diagonal direction (CDR2).

[0085] The first unit pixel (WPX) may include first-first pixels (WPXG1, WPXG2), first-second pixels (WPXR), and first-third pixels (WPXB). The first-first pixels (WPXG1, WPXG2) may provide first color light. The first-first pixels (WPXG1, WPXG2) may be arranged along the first direction (DR1).

[0086] The first-second pixel (WPXR) can provide a second color light different from the first color light. The first-second pixel (WPXR) can be spaced apart from one of the first-first pixels (WPXG1) along a first diagonal direction (CDR1) and can be spaced apart from another of the first-first pixels (WPXG2) along a second diagonal direction (CDR2).

[0087] The first-third pixel (WPXB) can provide third color light that is different from the first color light and the second color light. The first-third pixel (WPXB) can be spaced apart from one of the first-first pixels (WPXG1) along the second diagonal direction (CDR2), and can be spaced apart from another first-first pixel (WPXG2) along the first diagonal direction (CDR1).

[0088] The second unit pixel (NPX) may include 2-1 pixels (NPXG1, NPXG2), 2-2 pixels (NPXR), and 2-3 pixels (NPXB). The 2-1 pixels (NPXG1, NPXG2) may provide the first color light. The 2-1 pixels (NPXG1, NPXG2) may be arranged along the first direction (DR1).

[0089] The second-second pixel (NPXR) can provide the second color light. The second-second pixel (NPXR) can be spaced apart from one second-first pixel (NPXG1) along a first diagonal direction (CDR1) and can be spaced apart from another second-first pixel (NPXG2) along a second diagonal direction (CDR2).

[0090] The 2-3 pixel (NPXB) can provide the third color light. The 2-3 pixel (NPXB) can be spaced apart from one 2-1 pixel (NPXG1) along the second diagonal direction (CDR2) and can be spaced apart from another 2-1 pixel (NPXG2) along the first diagonal direction (CDR1).

[0091] In this embodiment, the first color light may be green, the second color light may be red, and the third color light may be blue. According to one embodiment, each of the first unit pixel (WPX) and the second unit pixel (NPX) may include one red pixel, one blue pixel, and two green pixels. However, this is only an example, and the number of each pixel may be different.

[0092] The area where light provided from pixels (WPXG1, WPXG2) is visible to the user may be defined as 1-1 transmissive areas (WPXAG1, WPXAG2). The area where light provided from pixels (WPXR) is visible to the user may be defined as 1-2 transmissive areas (WPXAR). The area where light provided from pixels (WPXB) is visible to the user may be defined as 1-3 transmissive areas (WPXAB).

[0093] The area where light provided from the 2-1 pixels (NPXG1, NPXG2) is visible to the user may be defined as the 2-1 transparent areas (NPXAG1, NPXAG2). The area where light provided from the 2-2 pixel (NPXR) is visible to the user may be defined as the 2-2 transparent areas (NPXAR). The area where light provided from the 2-3 pixel (NPXB) is visible to the user may be defined as the 2-3 transparent areas (NPXAB).

[0094] According to one embodiment, among the transparent regions defined in the first region (A1) and the second region (A2), the transparent regions (WPXAR, NPXAR) that provide red light may have an area larger than that of the transparent regions (WPXAG1, WPXAG2, NPXAG1, NPXAG2) that provide green light and may be smaller than that of the transparent regions (WPXAB, NPXAB) that provide blue light. For example, each of the transparent regions (WPXAR, NPXAR) may be larger than each of the transparent regions (WPXAG1, WPXAG2, NPXAG1, NPXAG2) and may be smaller than each of the transparent regions (WPXAB and NPXAB).

[0095] However, it is not limited thereto, and the areas of the transparent areas (WPXAG1, WPXAG2, WPXAR, WPXAB) defined in the first area (A1) may be the same as each other, and the areas of the transparent areas (NPXAG1, NPXAG2, NPXAR, NPXAB) defined in the second area (A2) may be the same as each other, and is not limited to any embodiment.

[0096] According to the present invention, the light control layer (300, see FIG. 3) may include a first light-blocking layer (310) and a second light-blocking layer (350). The transparent regions (WPXAG1, WPXAG2, WPXAR, WPXAB) in the first region (A1) may be defined by openings (310-OP) included in the first light-blocking layer (310) overlapping the first region (A1), and the transparent regions (NPXAG1, NPXAG2, NPXAR, NPXAB) in the second region (A2) may be defined by pattern openings (350-OP) included in the first pattern (350-P) of the second light-blocking layer (350).

[0097] According to the present invention, the first light-blocking layer (310) may be disposed throughout the first areas (A1) and the second areas (A2). The second light-blocking layer (350) may be disposed only in the second areas (A2). The second light-blocking layer (350) may include a first pattern (350-P) and a second pattern (350-S, “outer pattern” in the claims). The first pattern (350-P) may be a portion of the second light-blocking layer (350) disposed in the display area (DA), and the second pattern (350-S) may be a portion of the second light-blocking layer (350) disposed in the non-display area (NDA). The second pattern (350-S) will be described with reference to FIGS. 7A to 7C.

[0098] The first pattern (350-P) may include first to fourth shading patterns (350-G1, 350-G2, 350-R, 350-B), bridge patterns (350-C), and a connection pattern (350-I). Each of the first to fourth shading patterns (350-G1, 350-G2, 350-R, 350-B) may include pattern openings (350-OP) that overlap one-to-one with openings (310-OP) of the first shading layer (310).

[0099] The connecting pattern (350-I) may be a pattern connecting different second regions (A2) spaced apart along the first direction (DR1) or the second direction (DR2). According to one embodiment, the connecting pattern (350-I) may be a pattern connecting different second regions (A2) whose edges are adjacent to each other in the first direction (DR1) or the second direction (DR2). For example, the connecting pattern (350-I) may be arranged between the second shading pattern (350-G2) arranged in the second region (A2) on the right and the first shading pattern (350-G1) arranged in the second region (A2) on the left.

[0100] For convenience of explanation, FIG. 4A illustrates one connection pattern (350-I), but connection patterns (350-I) for connecting to second regions (A2) spaced apart along the first direction (DR1) and the second direction (DR2) may be connected to the first to fourth shading patterns (350-G1, 350-G2, 350-R, 350-B) arranged inside one second region (A2). For example, a connecting pattern (350-I) can connect a third shading pattern (350-R) and a fourth shading pattern (350-B) of adjacent second areas (A2) in a second direction (DR2), and another connecting pattern (350-I) can connect a first shading pattern (350-G1) and a second shading pattern (350-G2) of adjacent second areas (A2) in a first direction (DR1). This configuration can be equally applied throughout the display area (DA).

[0101] According to the present embodiment, the openings (310-OP) defined in the first shading layer (310) may have a circular shape. Accordingly, the transmission areas (WPXAG1, WPXAG2, WPXAR, WPXAB) defined in the first areas (A1) may have a circular shape in a plane.

[0102] The pattern opening (350-OP) defined in each of the light-shielding patterns of the light-shielding layer (350) may have a circular shape. Accordingly, the transmission areas (NPXAG1, NPXAG2, NPXAR, NPXAB) defined in the second areas (A2) may have a circular shape on a plane.

[0103] According to the present embodiment, the area of ​​the opening (310-OP) may be larger than the area of ​​the pattern opening (350-OP). Accordingly, the transparent areas (WPXAG1, WPXAG2, WPXAR, WPXAB) defined in the first region (A1) may have larger areas than the transparent areas (NPXAG1, NPXAG2, NPXAR, NPXAB) defined in the second region (A2). In Fig. 4a, the openings (310-OP) in the second region (A2) are illustrated with dotted lines.

[0104] In the display device (DD, see FIG. 2) according to the present invention, in the second mode, which is the private mode, light is not provided in the transparent areas defined in the first area (A1), and light can be provided only in the transparent areas defined in the second area (A2). Therefore, in the second mode, when the display device (DD) is viewed from an angle exceeding a certain viewing angle, images (IM, see FIG. 1) may not be visible.

[0105] Figure 4b focuses on explaining the differences from Figure 4a.

[0106] Referring to FIG. 4b, a first unit pixel (WPX-1) and a second unit pixel (NPX-1) may be arranged in the display area (DA-1). The first unit pixel (WPX-1) may include pixels having a relatively wide viewing angle, and the second unit pixel (NPX-1) may include pixels having a relatively narrow viewing angle.

[0107] According to the present invention, the display area (DA-1) may be arranged with first areas (A1) and second areas (A2). One first area (A1) may be defined as an area where one first unit pixel (WPX-1) is arranged, and one second area (A2) may be defined as an area where one second unit pixel (NPX-1) is arranged.

[0108] The first unit pixel (WPX-1) may include first-first pixels (WPXG1, WPXG2), first-second pixels (WPXR), and first-third pixels (WPXB). The second unit pixel (NPX-1) may include second-first pixels (NPXG1, NPXG2), second-second pixels (NPXR), and second-third pixels (NPXB).

[0109] According to the present invention, the light control layer (300, see FIG. 3) may include a first light-blocking layer (310) and a second light-blocking layer (350). The transparent regions (WPXAG1, WPXAG2, WPXAR, WPXAB) in the first region (A1) may be defined by openings (310-OP) included in the first light-blocking layer (310) overlapping the first region (A1), and the transparent regions (NPXAG1, NPXAG2, NPXAR, NPXAB) in the second region (A2) may be defined by pattern openings (350-OP) included in the first pattern (350-P) of the second light-blocking layer (350).

[0110] According to the present invention, the first light-blocking layer (310) may be disposed throughout the first areas (A1) and the second areas (A2). The second light-blocking layer (350) may be disposed only in the second areas (A2). The second light-blocking layer (350) may include a first pattern (350-P) and a second pattern (350-S).

[0111] The first pattern (350-P) may include a plurality of first to fourth shading patterns (350-G1, 350-G2, 350-R, 350-B), bridge patterns (350-C), and a connection pattern (350-I). Each of the first to fourth shading patterns (350-G1, 350-G2, 350-R, 350-B) may include pattern openings (350-OP) that overlap one-to-one with openings (310-OP) of the first shading layer (310).

[0112] According to the present embodiment, the shape of the openings (310-OP) defined in the first shading layer (310) and the shape of the pattern openings (350-OP) defined in each of the first to fourth shading patterns (350-G1, 350-G2, 350-R, 350-B) may be different. For example, the openings (310-OP) defined in the first shading layer (310) may have an elliptical shape.

[0113] Accordingly, the transmission areas (WPXAG1, WPXAG2, WPXAR, WPXAB) defined in the first areas (A1) may have an elliptical shape on a plane. The elliptical shape of the openings (310-OP) may have an elliptical shape according to a certain rule or may have a random elliptical shape.

[0114] The pattern opening (350-OP) defined in each of the first to fourth shading patterns (350-G1, 350-G2, 350-R, 350-B) may have a circular shape. Accordingly, the transmission areas (NPXAG1, NPXAG2, NPXAR, NPXAB) defined in the second areas (A2) may have a circular shape on a plane.

[0115] However, it is not limited thereto, and the pattern opening (350-OP) defined in each of the first to fourth shading patterns (350-G1, 350-G2, 350-R, 350-B) may have an elliptical shape corresponding to the overlapping opening (310-OP), and is not limited to any one embodiment.

[0116] According to the present embodiment, the area of ​​the opening (310-OP) may be larger than the area of ​​the pattern opening (350-OP). Accordingly, the transparent areas (WPXAG1, WPXAG2, WPXAR, WPXAB) defined in the first region (A1) may have larger areas than the transparent areas (NPXAG1, NPXAG2, NPXAR, NPXAB) defined in the second region (A2). The openings (310-OP) defined in the second region (A2) are indicated by dotted lines.

[0117] According to one embodiment, among the transparent regions defined in the first region (A1) and the second region (A2), the transparent regions (WPXAR, NPXAR) that provide red light may have an area larger than that of the transparent regions (WPXAG1, WPXAG2, NPXAG1, NPXAG2) that provide green light and may be smaller than that of the transparent regions (WPXAB, NPXAB) that provide blue light. For example, each of the transparent regions (WPXAR, NPXAR) may be larger than each of the transparent regions (WPXAG1, WPXAG2, NPXAG1, NPXAG2) and smaller than each of the transparent regions (WPXAB, NPXAB).

The first-first color filter (W320G1) may transmit light emitted from the first-first pixel (WPXG1), and the first-second color filter (W320R) may transmit light emitted from the first-second pixel (WPXR). The color filter layer (320) may include a 1-1 color filter overlapping the 1-1 pixel (WPXG1) described in FIG. 4a and a 1-3 color filter overlapping the 1-3 pixel (WPXB).

[0161] The color filter layer (320) may include a second-first color filter (N320G1) and a second-second color filter (N320R) arranged in the second region (A2). Each of the second-first color filter (N320G1) and the second-second color filter (N320R) may be arranged inside an opening (310-OP) defined in the second region (A2). The second-first color filter (N320G1) may transmit light emitted from the second-first pixel (NPXG1), and the second-second color filter (N320R) may transmit light emitted from the second-second pixel (NPXR). The color filter layer (320) may include a 2-1 color filter overlapping the 2-1 pixel (NPXG1) described in FIG. 4a and a 2-3 color filter overlapping the 2-3 pixel (NPXB).

[0162] The cover inorganic layer (330) may be arranged commonly in the first region (A1) and the second region (A2) (for example, it may cover or overlap the entire first region (A1) and the second region (A2) as one common layer). The cover inorganic layer (330) may cover the color filter layer (320). The cover inorganic layer (330) may protect the color filter layer (320) and the first light-shielding layer (310) from moisture and oxygen. The cover inorganic layer (330) may include a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer.

[0163] The planarization layer (340) may be commonly disposed in the first region (A1) and the second region (A2) (for example, it may cover or overlap the entire first region (A1) and the second region (A2) as one common layer). The planarization layer (340) may cover the first light-blocking layer (310) and the color filter layer (320). The planarization layer (340) may include an organic material and may provide a planar surface on the upper surface of the planarization layer (340). The planarization layer (340) may be formed by an inkjet process. In one embodiment, the planarization layer (340) may be omitted.

[0164] The over-coating layer (360) may be commonly disposed in the first region (A1) and the second region (A2). The over-coating layer (360) may cover the planarization layer (340). According to the present invention, the over-coating layer (360) may be disposed on the planarization layer (340) in the first region (A1). Specifically, since the second light-blocking layer (350) is not disposed in the first region (A1), the lower surface of the over-coating layer (360) in the first region (A1) may be in full contact with the upper surface of the planarization layer (340) (for example, the entire lower surface of the over-coating layer (360) may be in full contact with the upper surface of the planarization layer (340).

[0165] As illustrated in FIG. 5b, the light control layer (300) according to the present invention may include a second light-shielding layer (350) disposed only in the second region (A2). The second light-shielding layer (350) may be disposed on the planarization layer (340) and covered by an overcoating layer (360).

[0166] The second light-shielding layer (350) of the display device (DD) according to the present invention may be a functional layer arranged to emit light at a narrow viewing angle in the second mode, which is a private mode. Therefore, in the second mode, only second unit pixels (NPX, see FIG. 4A) overlapping the second light-shielding layer (350) may be driven. The second light-shielding layer (350) may be arranged in a plurality of light-shielding patterns, and pattern openings (350-OP) may be defined in each of the light-shielding patterns. Each of the pattern openings (350-OP) may overlap with an opening (310-OP) defined in the second area (A2) of the first light-shielding layer (310).

[0167] FIG. 6b illustrates the shape of the second shading layer (350) arranged in the second areas (A2) on a plane. The second shading layer (350) may include a first pattern (350-P) and a second pattern (350-S).

[0168] The first pattern (350-P) may include first to fourth shading patterns (350-G1, 350-G2, 350-R, 350-B), bridge patterns (350-C), and a connection pattern (350-I). Each of the first to fourth shading patterns (350-G1, 350-G2, 350-R, 350-B) may include pattern openings (350-OP) that overlap one-to-one with openings (310-OP) of the first shading layer (310). For example, the first shading pattern (350-G1) may overlap with the opening (310-OP) corresponding to the 2-1 pixel (NPXG1), the second shading pattern (350-G2) may overlap with the opening (310-OP) corresponding to the 2-1 pixel (NPXG2), the third shading pattern (350-R) may overlap with the opening (310-OP) corresponding to the 2-2 pixel (NPXR), and the fourth shading pattern (350-B) may overlap with the opening (310-OP) corresponding to the 2-3 pixel (NPXB).

[0169] The first shading pattern (350-G1) may be spaced apart from the second shading pattern (350-G2) along the first direction (DR1). The third shading pattern (350-R) may be spaced apart from the first shading pattern (350-G1) along the first diagonal direction (CDR1) and may be spaced apart from the second shading pattern (350-G2) along the second diagonal direction (CDR2).

[0170] The shading pattern (350-B) may be spaced apart from the third shading pattern (350-R) along the second direction (DR2), spaced apart from the first shading pattern (350-G1) along the second diagonal direction (CDR2), and spaced apart from the second shading pattern (350-G2) along the first diagonal direction (CDR1).

[0171] The bridge patterns (350-C) may be arranged between the shading patterns spaced apart from each other within one second region (A2). For example, each of the bridge patterns (350-C) may be arranged between the shading patterns spaced apart along the first diagonal direction (CDR1) or the second diagonal direction (CDR2), thereby connecting the shading patterns to each other.

[0172] However, it is not limited thereto, and the first pattern (350-P) may further include bridge patterns arranged between the light-shielding patterns spaced apart along the first direction (DR1) or the second direction (DR2) within one second area (A2), and is not limited to any one embodiment.

[0173] The connecting pattern (350-I) may be a pattern that connects different second regions (A2) spaced apart along the first direction (DR1) or the second direction (DR2). In one embodiment, the connecting pattern (350-I) may be a pattern that connects different second regions (A2) whose edges are adjacent to each other in the first direction (DR1) or the second direction (DR2). For example, the connecting pattern (350-I) may be arranged between the second shading pattern (350-G2) arranged in the second region (A2) on the right and the first shading pattern (350-G1) arranged in the second region (A2) on the left.

[0174] According to the present invention, the light-shielding patterns arranged within the display area (DA) can be connected to each other not only with the patterns arranged in the same second area (A2), but also with the light-shielding patterns arranged in second areas (A2) spaced apart from each other along the first direction (DR1) and the second direction (DR2). Accordingly, a display device including light-shielding patterns with increased bonding strength can be provided.

[0175] In this embodiment, each of the shading patterns (350-G1, 350-G2, 350-R, 350-B) may have a ring shape. Each of the ring-shaped shading patterns (350-G1, 350-G2, 350-R, 350-B) may surround an opening (310-OP) on a plane.

[0176] The area of ​​the pattern opening (350-OP) defined in the second region (A2) may be smaller than the area of ​​the opening (310-OP) defined in the second region (A2) of the first light-shielding layer (310). For example, the inner edge of each of the light-shielding patterns (350-G1, 350-G2, 350-R, 350-B) may overlap with the opening (310-OP) corresponding to each pixel. Accordingly, the second unit pixels (NPX, see FIG. 4a) overlapping the second region (A2) may have a narrower viewing angle compared to the first unit pixels (WPX, see FIG. 4a).

[0177] According to the present invention, the transmission areas (NPXAG1, NPXAG2, NPXAR, NPXAB) through which light generated in the second unit pixel (NPX, see FIG. 4a) passes can be defined by pattern openings (350-OP) defined in the second light-shielding layer (350).

[0178] In this embodiment, the areas of the pattern openings (350-OP) may be the same. However, this is not limited thereto, and the areas of the pattern openings (350-OP) through which different lights are transmitted may be different from each other, and the present invention is not limited to any embodiment.

[0179] The second shading layer (350) may be formed of substantially the same material as the first shading layer (310). Accordingly, the second shading layer (350) may prevent reflection of external light and may include a black component that absorbs light.

[0180] In one embodiment of the present invention, the second unit pixels (NPX, see FIG. 4a) can be driven in both the first mode, which is a normal mode, and the second mode, which is a private mode. In the second mode, which is a private mode, the first unit pixels (WPX, see FIG. 4a) can be non-driven. Therefore, the second mode can display an image with a narrower viewing angle than the first mode.

[0181] Again, comparing FIGS. 5A and 5B, the first region (A1) may include a first shading layer (310) having openings (310-OP) defined therein, but may not include a second shading layer (350). Therefore, in the first mode, light emitted from the first and second light-emitting elements (WOLR) at the first angle (AG1) and the second angle (AG2) may be visible to the user and an outsider viewing from a high angle.

[0182] On the other hand, the second region (A2) may include a first light-shielding layer (310) having defined openings (310-OP) and a second light-shielding layer (350) having defined pattern openings (350-OP). As described above, the area of ​​the pattern openings (350-OP) is smaller than the area of ​​the openings (310-OP), so that in the first mode and the second mode, light emitted from the second-first light-emitting element (WPLR) at the first angle (AG1) and the second angle (AG2) may not be visible to an outsider.

[0183] According to the present invention, when a second shading layer (350) is also formed, a narrower viewing angle can be achieved compared to a structure in which only a first shading layer (310) is formed. When a narrower viewing angle is formed, a strong private mode can be achieved, thereby providing a display device (DD) with enhanced privacy protection.

[0184] Fig. 7a is a plan view illustrating a second shading layer according to one embodiment of the present invention. Fig. 7b is an enlarged plan view of area AA' of Fig. 7a. Fig. 7c is an enlarged plan view of area BB' of Fig. 7a. Fig. 7a illustrates the shape of the second shading layer (350) in a plan view.

[0185] The second shading layer (350) may be placed on the flattening layer (340). The flattening layer (340) is depicted in a dotted line for convenience of explanation.

[0186] The second shading layer (350) may include a first pattern (350-P) and a second pattern (350-S). The first pattern (350-P) may include first to fourth shading patterns (350-G1, 350-G2, 350-R, 350-B), bridge patterns (350-C), and a connection pattern (350-I). The description of the first pattern (350-P) may be the same as that described with reference to FIGS. 5A to 6B.

[0187] Referring to FIGS. 7A to 7C, the second shading layer (350) may include a second pattern (350-S) and dummy patterns (350-D) arranged in a non-display area (NDA).

[0188] The second pattern (350-S) may surround the first pattern (350-P). The second pattern (350-S) may include first portions (PS) extending along the first direction (DR1), second portions (PL) extending along the second direction (DR2), and corner portions (PC) arranged between the first portions (PS) and the second portions (PL).

[0189] The first portions (PS) may be spaced apart along the second direction (DR2) with the display area (DA) interposed therebetween. The second portions (PL) may be spaced apart along the first direction (DR1) with the display area (DA) interposed therebetween. The first portions (PS) may be relatively shorter than the second portions (PL). According to one embodiment, the corner portions (PC) may have a predetermined curvature. Accordingly, the corners of the second pattern (350-S) may have a rounded shape.

[0190] The second pattern (350-S) may be arranged along the non-display area (NDA) and surround the light-shielding patterns (350-G1, 350-G2, 350-R, 350-B) included in the first pattern (350-P). Accordingly, the second pattern (350-S) may have a closed-line shape (ring shape) arranged in the non-display area (NDA).

[0191] According to the present invention, the second pattern (350-S) can be connected to the light-shielding patterns (350-G1, 350-G2, 350-R, 350-B). In addition, the second pattern (350-S) can be patterned by the same process as the first pattern (350-P). Therefore, the second pattern (350-S) can be arranged on the same layer as the first pattern (350-P) and can include the same material.

[0192] The second pattern (350-S) may overlap with the bezel pattern of the window defining the appearance of the display device (DD) and may not be visible to the user.

[0193] According to the present invention, the second pattern (350-S) can be connected to the first pattern (350-P) arranged within the display area (DA). The second pattern (350-S) can be connected to any one of the light-shielding patterns (350-G1, 350-G2, 350-R, 350-B), the bridge patterns (350-C), and the connection patterns (350-I). Therefore, the first pattern (350-P) and the second pattern (350-S) can be provided in the form of an integral pattern (one-body).

[0194] If there is no second pattern (350-S) connected to the first pattern (350-P), one of the shading patterns (350-G1, 350-G2, 350-R, 350-B), bridge patterns (350-C), and connecting patterns (350-I) arranged at the boundary between the display area (DA) and the non-display area (NDA) has weaker bonding strength than the adjacent patterns, causing a lifting phenomenon at the boundary between the display area (DA) and the non-display area (NDA), which may deteriorate the display quality.

[0195] According to the present invention, since the patterns arranged on the second light-blocking layer (350) are provided as an integral pattern, the phenomenon of patterns arranged adjacent to the boundary between the display area (DA) and the non-display area (NDA) among the patterns included in the first pattern (350-P) being lifted can be prevented. Accordingly, the quality of the display device (DD) capable of operating in two modes can be improved.

[0196] According to one embodiment, the second light-blocking layer (350) may include dummy patterns (350-D) arranged in the non-display area (NDA). The dummy patterns (350-D) may be defined as patterns included in the first pattern (350-P) that are arranged in the non-display area (NDA) and have a portion of the shape of the patterns included in the first pattern (350-P) removed. For example, the dummy pattern (350-D) may be located in the non-display area (NDA), but may be formed by extending the pattern of the first pattern (350-P) in the display area (DA), as illustrated in FIG. 7B. Accordingly, the dummy pattern (350-D) may have a shape that is substantially similar to or identical to a portion of the shape of the first pattern (350-P) in the display area (DA). The dummy patterns (350-D) may be arranged between the patterns included in the first pattern (350-P) and the second pattern (350-S). However, it is not limited thereto, and the dummy patterns (350-D) may be omitted, and the second pattern (350-S) may be directly connected to the patterns included in the first pattern (350-P).

[0197] Fig. 8 is a plan view illustrating a portion of a second shading layer according to one embodiment of the present invention. The same / similar reference numerals are used for configurations identical / similar to those described in Figs. 4a to 7c, and duplicate descriptions are omitted.

[0198] Referring to FIG. 8, the second light-blocking layer (350-A) may include a first pattern (350-P), a dummy pattern (350-D), and a second pattern (350-S). According to one embodiment, the second pattern (350-S) may include a plurality of patterns (PP). The plurality of patterns (PP) may be arranged in the non-display area (NDA) along the boundary between the display area (DA) and the non-display area (NDA). When the patterns arranged along the first direction (DR1) among the patterns included in the first pattern (350-P) are defined as a group pattern, three group patterns may be connected to one pattern (PP). However, two or more group patterns may be connected to one pattern (PP), and the present invention is not limited to any one embodiment.

[0199] According to the present embodiment, if a defect occurs in any one of the patterns included in the first pattern (350-P), only the group patterns connected to the defective pattern and one pattern (PP) connected thereto can be removed. Accordingly, the defective pattern among the patterns included in the first pattern (350-P) can be easily removed and re-formed or a repair process can be performed.

[0200] Fig. 9a is a plan view illustrating a display panel according to one embodiment of the present invention. Fig. 9b is an enlarged plan view of the CC' region of Fig. 9a. The same / similar reference numerals are used for configurations identical / similar to those described in Figs. 4a to 7c, and duplicate descriptions are omitted.

[0201] Referring to FIG. 9A, a display device (DD-H) according to one embodiment may include a hole area (HA), a display area (DA), and a non-display area (NDA). The hole area (HA) may be positioned within the display area (DA).

[0202] A display device (DD-H) according to one embodiment may define a module hole (MH) overlapping with a hole area (HA). The hole area (HA) may be formed by penetrating the display layer (100) included in the display panel (DP) described in FIG. 3 through the base layer (110), the circuit layer (120), the light-emitting element layer (130), the encapsulation layer (140), and the sensor layer (200). The module hole (MH) may be covered by the light control layer (300) and the window.

[0203] A display device (DD-H) according to one embodiment may further include a camera module (CM). The camera module (CM) may overlap the module hole (MH). At least a portion of the camera module (CM) may be positioned within the module hole (MH) or may be positioned below the display panel (DP) described in FIG. 3.

[0204] According to the present embodiment, by arranging the camera module (CM) within the display area (DA), the separate area for arranging the camera module (CM) can be reduced. Accordingly, an unnecessary increase in the non-display area (NDA) can be prevented.

[0205] Referring to FIG. 9b, the second shading layer (350-a) according to one embodiment may include a first pattern (350-P), a second pattern (350-S, see FIG. 7a), and a third pattern (350-H, “hole pattern” in the claim). The description of the first pattern (350-P) and the not-shown second pattern (350-S, see FIG. 7a) may be the same as the description of FIGS. 4a to 7c.

[0206] The third pattern (350-H) may be arranged in the hole area (HA). The third pattern (350-H) may have a ring shape surrounding the module hole (MH). The third pattern (350-H) may be connected to patterns included in the first pattern (350-P) arranged in the display area (DA). In addition, the third pattern (350-H) may be patterned by the same process as the first pattern (350-P). Therefore, the third pattern (350-H) may be arranged on the same layer as the first pattern (350-P) and may include the same material.

[0207] According to the present embodiment, even if a module hole (MH) defined within the display area (DA) is included, since the patterns included in the third pattern (350-H) and the first pattern (350-P) are provided as an integral pattern, the phenomenon of patterns arranged adjacent to the boundary between the display area (DA) and the hole area (HA) being lifted can be prevented. Accordingly, the quality of the display device (DD-H) capable of operating in two modes can be improved.

[0208] According to one embodiment, the second shading layer (350-a) may include dummy patterns (350-D) arranged in a non-display area (NDA). The dummy patterns (350-D) may be arranged in a hole area (HA) among the patterns included in the first pattern (350-P), and may be defined as having a portion of the shape of the patterns included in the first pattern (350-P) removed.

[0209] For example, the dummy pattern (350-D) may be positioned in the hole area (HA), but may be formed by extending the pattern of the first pattern (350-P) in the display area (DA), as illustrated in FIG. 9B. Accordingly, the dummy pattern (350-D) may have a shape substantially similar to or identical to a portion of the shape of the first pattern (350-P) in the display area (DA).

[0210] Dummy patterns (350-D) may be placed between the patterns included in the first pattern (350-P) and the third pattern (350-H). However, this is not limited thereto, and the dummy patterns (350-D) may be omitted, and the third pattern (350-H) may be directly connected to the patterns included in the first pattern (350-P).

[0211] According to the present invention, the patterns arranged in the light-shielding layer are provided as a single pattern, thereby preventing the patterns arranged adjacent to the boundary between the display area and the non-display area from being lifted. Accordingly, the display quality and reliability of a display device capable of operating in two modes can be improved.
