[0001] This application claims priority to Korean Patent Application No. 10-2025-0015247, filed on February 6, 2025, with the Korean Intellectual Property Office, and Korean Patent Application No. 10-2025-0081319, filed on June 19, 2025, the entire disclosure of which is incorporated herein by reference. Technical Field

[0003] Display devices are used in various electronic devices, such as televisions, mobile phones, tablet computers, and electronic devices included in vehicles. Due to the importance of display devices in a wide range of applications, continuous efforts are being made to develop and improve them. Depending on the usage environment, the information in a display device may need to be protected, or it may need to be controlled in other ways to comply with various regulations, such as security regulations. To achieve these goals, the viewing angle of the display device must be limited. Therefore, to limit the viewing angle of display devices, the stacking structure of display devices and the optical components included in display devices have been studied. However, further improvements to display device technology are needed to limit the viewing angle of display devices. Summary of the Invention

[0074] Terms such as first and second may be used to describe various components, but these components are not limited by the use of these terms. These terms may be used only for the purpose of distinguishing one component from other components. For example, without departing from the scope of this disclosure, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component. Unless otherwise stated, singular terms may include plural forms.
[0075] Furthermore, terms such as "below," "under," "above," and "on top of" are used to describe the relationships between the components shown in the accompanying drawings. These terms are relative concepts and are described based on the directions shown in the drawings or multiple drawings.
[0076] 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 this disclosure pertains. Unless expressly defined as having such a feature in this application, such terms (as defined in a general dictionary) should be interpreted as having a meaning equivalent to that in the context of the relevant field and should not be interpreted in an idealized or overly formalized sense.
[0077] In the following description, embodiments of the present disclosure will be described with reference to the accompanying drawings.
[0078] Figure 1 This is a block diagram of an electronic device according to an embodiment of the present disclosure.
[0079] The electronic device according to this disclosure can be provided in various forms. Some embodiments of the electronic device according to this disclosure may include modules or devices having functions other than those of the display device included in the electronic device.
[0080] refer to Figure 1The electronic device ED according to the embodiments may include a display device DD, a processor PR, a memory MR, and a power module PM. Throughout this disclosure, modules that provide electrical signals to or receive electrical signals from the display device DD may be collectively referred to as "electronic modules".
[0081] The processor PR may include at least one of a central processing unit (CPU), an application processor (AP), a graphics processing unit (GPU), a communication processor (CP), an image signal processor (ISP), and a controller.
[0082] The data required for the operation of the processor PR or the display device DD can be stored in the memory MR. When the processor PR executes the application stored in the memory MR, image data signals and / or input control signals can be transmitted to the display device DD, and the display device DD can process the received signals and output image information through the display screen.
[0083] The power module (PM) may include a power supply module such as a power adapter or battery device, and a power conversion module that converts the power supplied by the power supply module and generates the power required for the operation of the electronic device (ED).
[0084] Some of the individual modules that are functionally included in a module may be included in the display device DD, and other modules may be provided separately from the display device DD in the electronic device ED.
[0085] Figure 2A and Figure 2B Schematic diagrams of electronic devices according to various embodiments are shown.
[0086] refer to Figure 2A According to various embodiments, the electronic device may be a wearable electronic device including a display module (such as smart glasses ED-2a, head-mounted display ED-2b or smartwatch ED-2c), and an electronic device for displaying images (such as a smartphone ED-1a, tablet PC ED-1b, laptop computer ED-1c, television (TV) ED-1d or desktop monitor ED-1e).
[0087] Furthermore, electronic devices according to various embodiments can be equipped in transmission devices such as vehicles to provide various information to users through images displayed in such transmission devices. For example, electronic devices according to this disclosure can be provided in the form of vehicle electronic devices ED-3 including a display module (such as a central information display (CID) or an in-vehicle rearview mirror display disposed on / in the instrument panel, central dashboard, or dashboard of a vehicle).
[0088] Figure 2BThis is a view showing the interior of a vehicle in which an embodiment of the electronic device is installed. Figure 2B The illustration shows, as an example, a first electronic device ED-PS and a second electronic device ED-CT arranged inside the vehicle's AM. The electronic devices ED-CT and ED-PS of the embodiment can be located inside the vehicle's AM to provide various information to a user in (or at) the driver's seat DRS or passenger seat PSS.
[0089] Electronic devices such as ED-CT and ED-PS can display images on a display surface IS. The display surface IS can correspond to the front surface of the ED-CT or ED-PS device. Images can include still images and moving images.
[0090] The display surface IS may be oriented parallel to a plane that coincides with a first direction DR1 and a second direction DR2 that intersects the first direction DR1. However, embodiments of this disclosure are not limited thereto, and the display surface IS of the electronic devices ED-CT and ED-PS may include a curved surface to reflect the design of the vehicle interior, or may include a flat surface that is inclined relative to a plane that coincides with the first direction DR1 and the second direction DR2.
[0091] The normal direction of the display surface IS (that is, the thickness direction of the electronic devices ED-CT and ED-PS) is indicated by a third direction DR3. Throughout this disclosure, the first direction DR1 may be referred to as the "left-right direction", the second direction DR2 may be referred to as the "up-down direction", and the third direction DR3 may be referred to as the "thickness direction".
[0092] Throughout this disclosure, the electronic device ED (reference) constitutes Figure 1 The front (or upper) and rear (or lower) surfaces of the components constituting the electronic device ED may be defined based on a third direction DR3. The front (or upper) and rear (or lower) surfaces of the components constituting the electronic device ED may be opposite to each other on the third direction DR3, and the normal directions of the front and rear surfaces may be substantially parallel to the third direction DR3. The separation distance between the front and rear surfaces defined on the third direction DR3 may correspond to the thickness of the corresponding component of the electronic device ED, including any component or assembly of the display device contained therein.
[0093] Furthermore, as used herein, the term "in a plane" may mean the referenced member or component viewed in a third direction DR3. The term "in a section" as used herein may mean the referenced member or component viewed in a first direction DR1 or a second direction DR2.
[0094] Figure 2BAn example of a display surface IS having a rectangular shape on a plane is shown. However, this is merely an illustrative example, and the display surface IS can have various shapes on a plane, and therefore the display surface IS is not limited to any one embodiment.
[0095] Throughout this disclosure, it should be understood that when referring to electronic devices ED (see reference ED), Figure 1 When this is used, the referenced electronic device ED can be configured to switch between a "first mode" and a "second mode". Electronic device ED (reference) Figure 1 It can provide different perspectives in the first mode and the second mode.
[0096] refer to Figure 2B The first electronic device ED-PS can be positioned facing the passenger seat PSS. The first electronic device ED-PS can display not only information needed during vehicle driving (such as vehicle status information, vehicle interior operation information, and navigation information), but also various information unrelated to vehicle driving.
[0097] However, for safety reasons, during vehicle operation, the image displayed in the first electronic device ED-PS does not need to be transmitted to the user in the driver's seat DRS. In other words, the range of the lateral viewing angle of the image displayed in the first electronic device ED-PS can be controlled so as not to affect the driver. This control to limit the lateral viewing angle for the driver can be guided by taking into account the field of vision of the user in the driver's seat DRS.
[0098] For example, the lateral viewing angle provided by the first electronic device ED-PS in the second mode may be smaller than the lateral viewing angle provided by the first electronic device ED-PS in the first mode. The image displayed in the first electronic device ED-PS can be visually recognized by the driver in the first mode, but may not be visually recognized by the driver in the second mode. Therefore, the optical path can be subject to the light control layer CCL (refer to...) which will be described later. Figure 3 The limitations of ED-PS are thus overcome, and therefore the first electronic device can advantageously provide the user with a highly visible image without interfering with the driver.
[0099] The second electronic device, ED-CT, can be a central information display (CID). The second electronic device, ED-CT, can be installed on / in the dashboard between the driver's seat DRS and the passenger seat PSS. The second electronic device, ED-CT, can display various information holistically to the user in either the driver's seat DRS or the passenger seat PSS.
[0100] In the case of a second electronic device ED-CT, it may be necessary to limit the viewing angle in the vertical direction (e.g., the second direction DR2). When the image displayed in the second electronic device ED-CT is displayed in a wide-angle range in the vertical direction, light emitted from the second electronic device ED-CT may reach the wind deflector WSD and may generate reflected light. In this case, the user's line of sight may be obstructed by the reflected light. In an embodiment, the light path in the vertical direction may be controlled by the light control layer CCL (refer to...) which will be described later. Figure 3 The limitations of the vehicle's AM (Advanced Driver Assistance System) and therefore the vehicle's AM (Advanced Driver Assistance System) second electronic device ED-CT can reduce the light transmitted to the windshield WSD to provide the user with an image with high visibility.
[0101] For example, the vertical viewing angle provided by the second electronic device ED-CT in both first and second modes may be limited. However, it is not limited thereto; the limitation of the viewing angle in either the first or second mode may include limitations of the viewing angle in any combination of the upward, downward, leftward, and rightward directions (i.e., in one, two, three, or four directions). In some examples, the limitation of the viewing angle in the first mode may differ from the limitation of the viewing angle in the second mode.
[0102] However, in the formation of the light control layer CCL (reference) Figure 3 In the process of forming the light control layer (CCL), a fine pattern must be formed that limits the viewing angle without reducing the user's visibility. Therefore, if the fine pattern is not formed sufficiently, the light control layer (CCL) will be affected. Figure 3 Defects may occur during the manufacturing process of the electronic device according to this disclosure. In one embodiment of the electronic device, defects may occur during the formation of the optical control layer CCL (reference 1). Figure 3 The light-blocking pattern BM in (reference) Figure 5B In the process of ), light blocking pattern BM (reference) can be effectively prevented. Figure 5B A portion of it was torn apart.

[0104] The electronic device ED may include a display device DD and a window module WM. The window module WM may be disposed on the display device DD.
[0105] The window module WM can be mounted on the display device DD and can cover the display device DD. The front surface of the window module WM can define the display surface IS of the electronic device ED (see reference). Figure 2B The window module WM can have a planar shape that corresponds to the planar shape of the display device DD.
[0106] The window module WM may include a substrate or film comprising glass or polymer material. Furthermore, the window module WM may also include a functional layer, such as a protective film, disposed on the substrate or film serving as a base. The window module WM may also include an adhesive layer for coupling the window module WM to the display device DD. For example, the adhesive layer may be an optically transparent adhesive layer. However, in the electronic device ED according to the embodiment, the window module WM may be omitted.
[0107] The display device DD may include a display panel DP and a light control layer CCL.
[0108] The display panel DP can be a component that substantially generates an image. The display panel DP included in the electronic device ED according to this embodiment can be an organic light-emitting display panel, an inorganic light-emitting display panel, an organic-inorganic light-emitting display panel, a quantum dot display panel, a micro light-emitting diode (LED) display panel, or a nano-LED display panel. In this embodiment, it will be exemplified that the display panel DP is an organic light-emitting display panel. However, embodiments of this disclosure are not limited thereto.
[0109] The display panel (DP) may include a substrate layer (BL), a circuit element layer (DP-CL), a display element layer (DP-ED), a packaging layer (TFE), and an input sensing layer (ISL).
[0110] In a display panel DP, the substrate layer BL can be a component that provides a substrate surface on which a circuit element layer DP-CL is disposed. The substrate layer BL can be rigid or flexible. The substrate layer BL can be a glass substrate, a metal substrate, or a polymer substrate. However, the embodiments of this disclosure are not limited thereto, and the substrate layer BL can be an inorganic layer, an organic layer, or a composite material layer.
[0111] The matrix layer BL can have a multilayer structure or a single-layer structure. For example, the matrix layer BL can have a three-layer structure including a polymer resin layer, an adhesive layer, and a polymer resin layer. Specifically, the polymer resin layer can include a polyimide resin. Alternatively, the polymer resin layer can include at least one of acrylic resins, vinyl resins, epoxy resins, urethane resins, cellulose resins, siloxane resins, and perylene resins. Furthermore, the term "~~" in this document refers to resins containing the "~~" functional group.
[0112] A circuit element layer DP-CL can be disposed on a substrate layer BL. The circuit element layer DP-CL may include an insulating layer, semiconductor patterns, conductive patterns, and signal lines. The circuit element layer DP-CL may include multiple transistors (not shown) formed from the semiconductor patterns, conductive patterns, and signal lines. Each of the multiple transistors (not shown) may include a control electrode, an input electrode, and an output electrode. For example, the circuit element layer DP-CL may include a switching transistor and a method for driving a light-emitting element OLED (reference). Figure 5C The driving transistor.
[0113] The display element layer DP-ED can be disposed on the circuit element layer DP-CL. Light generated from the display element layer DP-ED can pass through the light control layer CCL above the display element layer DP-ED and can be emitted onto the upper surface of the electronic device ED. The display element layer DP-ED may include a light-emitting element OLED (reference). Figure 5C ).
[0114] The encapsulation layer TFE can be disposed on the display element layer DP-ED. The encapsulation layer TFE can perform the function of preventing foreign matter such as moisture and oxygen from penetrating into the display element layer DP-ED. The encapsulation layer TFE can have a structure in which organic layers and inorganic layers are stacked alternately in succession.
[0115] A light control layer (CCL) can be disposed above the display element layer (DP-ED). The light control layer (CCL) can control the light extraction direction of the light emitted from the display element layer (DP-ED). According to the embodiments, an electronic device (ED) including a light control layer (CCL) can exhibit high brightness and excellent display quality within a limited viewing angle by limiting the light emitted widely in the "left-right direction" or limiting the light emitted widely in the "up-down direction".
[0116] An electronic device ED may include a display area DA and a non-display area NDA adjacent to the display area DA. In this embodiment, the non-display area NDA may be a region surrounding the display area DA. However, embodiments of this disclosure are not limited thereto. For example, the non-display area NDA may be omitted. In other examples, the non-display area NDA may not surround the display area DA.
[0117] The Input Sensing Layer (ISL) can be positioned below the Light Control Layer (CCL). The ISL acquires the coordinate information of external inputs. The ISL can sense external inputs using capacitive, electromagnetic induction, or pressure sensing methods.
[0118] Figure 4 This is a plan view showing a partial area of a display device according to an embodiment of the present disclosure.
[0119] refer to Figure 4The display device DD (e.g., substrate layer BL) according to this embodiment may include a light-emitting region LA and a non-light-emitting region NLA adjacent to the light-emitting region LA. The light-emitting region LA may be defined as a first electrode EL1 (refer to...). Figure 5B The upper surface of the pixel opening OH (refer to the pixel opening OH that will be described later) is located on the upper surface of the pixel opening OH. Figure 5B The exposed area. The luminescent area LA may include the first luminescent areas LA1-1 and LA1-2, the second luminescent areas LA2-1 and LA2-2, and the third luminescent areas LA3-1 and LA3-2.
[0120] In this embodiment, the first light-emitting regions LA1-1 and LA1-2 can be red light-emitting regions emitting red light, the second light-emitting regions LA2-1 and LA2-2 can be green light-emitting regions emitting green light, and the third light-emitting regions LA3-1 and LA3-2 can be blue light-emitting regions emitting blue light. However, the embodiments of this disclosure are not limited thereto. For example, the display device DD may also include white light-emitting regions emitting white light.
[0121] In this embodiment, the first emitting region LA1 may include a first-first emitting region LA1-1 and a first-second emitting region LA1-2. The second emitting region LA2 may include a second-first emitting region LA2-1 and a second-second emitting region LA2-2. The third emitting region LA3 may include a third-first emitting region LA3-1 and a third-second emitting region LA3-2. The first-first emitting region LA1-1 may have a larger planar area (i.e., emission surface area) than the first-second emitting region LA1-2, the second-first emitting region LA2-1 may have a larger planar area (emission surface area) than the second-second emitting region LA2-2, and the third-first emitting region LA3-1 may have a larger planar area (emission surface area) than the third-second emitting region LA3-2. In each of the plurality of planar areas compared above, the planar area is the area in the plane coinciding with the first direction DR1 and the second direction DR2.
[0122] In this embodiment, the light-emitting element OLED (reference) Figure 5CThe light-emitting element may include a "first type of light-emitting element" and a "second type of light-emitting element". Throughout this disclosure, the "first type of light-emitting element" and the "second type of light-emitting element" may also be referred to as "first type of light-emitting element" and "second type of light-emitting element", respectively. In this case, each of the first-first light-emitting region LA1-1, the second-first light-emitting region LA2-1, and the third-first light-emitting region LA3-1 may be a region therein that emits light through the "first type of light-emitting element". Each of the first-second light-emitting region LA1-2, the second-second light-emitting region LA2-2, and the third-second light-emitting region LA3-2 may be a region therein that emits light through the "second type of light-emitting element".
[0123] The "first type of light-emitting element" and the "second type of light-emitting element" can operate differently. For example, the first electronic device ED-PS (reference) Figure 2B It can operate both the "first type of light-emitting element" and the "second type of light-emitting element" in the first mode, and can operate only the "second type of light-emitting element" without operating the "first type of light-emitting element" in the second mode.
[0124] In addition, the second electronic device ED-CT (reference) Figure 2B It can operate both "first type light-emitting element" and "second type light-emitting element" in the first mode and the second mode, operate only "first type light-emitting element" or only "second type light-emitting element". In some examples, the types of light-emitting elements or combinations of light-emitting element types operating in the first mode and the second mode can be different from each other.
[0125] However, this is not the only limitation; the "first type of light-emitting element" and the "second type of light-emitting element" can be modified to operate differently as needed. Therefore, the electronic device ED (reference) can be adjusted. Figure 1 According to the driver's seat DRS (reference) Figure 2B ) and passenger seat PSS (reference) Figure 2B () visibility.
[0126] The non-luminescent area (NLA) can be defined by the light emanating from the display area (DA) (reference). Figure 3 The region obtained by excluding the luminescent region LA. The non-luminescent region NLA can be represented as the "peripheral region NLA". The peripheral region NLA can be set around the luminescent region LA. The peripheral region NLA can define the boundary of the luminescent region LA.
[0127] In this embodiment, the pixel unit PXU can be located in the display area DA (reference). Figure 3 The pixel units (PXU) are arranged in the first direction DR1 and the second direction DR2. The pixel units (PXU) can define pixel rows and pixel columns.
[0128] Each of the multiple pixel units (PXUs) may include at least one pixel. A PXU may include a first pixel, a second pixel, and a third pixel that emit light in different wavelength ranges. The first pixel, the second pixel, and the third pixel may output red light, green light, and blue light, respectively.
[0129] like Figure 4 As shown, the width of the pixel unit PXU in the first direction DR1 can be defined as "unit pitch W-PU". A description of this unit pitch W-PU is included later. Figure 4 In this configuration, each pixel unit PXU includes two rows of light-emitting regions arranged in a first direction DR1, and these rows are continuous to adjacent pixel units PXU. In this way, the top row shown may include six light-emitting regions, and a subset of the six light-emitting regions is in the upper left pixel unit PXU (i.e., three of the six light-emitting regions in the top row are in the upper left pixel unit PXU).
[0130] In this embodiment, the first light-emitting regions LA1-1 and LA1-2 can be regions where light generated from the first pixel is provided to the outside, the second light-emitting regions LA2-1 and LA2-2 can be regions where light generated from the second pixel is provided to the outside, and the third light-emitting regions LA3-1 and LA3-2 can be regions where light generated from the third pixel is provided to the outside. However, the embodiments of this disclosure are not limited thereto, and the type and number of light-emitting regions constituting a pixel unit PXU can vary depending on the display quality required by the display device.
[0131] Figure 5A yes Figure 4 An enlarged plan view of a component in a local area. Figure 5B It corresponds to Figure 5A A cross-sectional view of line I-I'. Figure 5C It corresponds to Figure 5A The cross-sectional view of line II-II'.
[0132] For ease of description, Figure 5A The image shows the first optical control layer CCL1 (reference). Figure 5B The first light-blocking pattern BM1 in the diagram is omitted, and the second light-blocking pattern BM2 is omitted (see reference). Figure 5B ), third light-blocking pattern BM3 (reference) Figure 5B ) and the fourth light-blocking pattern BM4 (reference) Figure 5B However, the following reference Figures 5A to 6B The description of the first light-blocking pattern BM1 can be applied in the same or similar way to the second light-blocking pattern BM2 (see reference). Figure 5B ), third light-blocking pattern BM3 (reference) Figure 5B) and the fourth light-blocking pattern BM4 (reference) Figure 5B (and omit repeated descriptions.) In the following text, the arrangement of the light control layer and the light-emitting region (including the relationship between the light control layer and the light-emitting region) will be described with reference to the accompanying drawings.
[0133] Figure 5A It is a view showing the arrangement of the light-emitting area LA and the first light-blocking pattern BM1, as well as the relationship between the light-emitting area LA and the first light-blocking pattern BM1. Figure 5B It is along Figure 5A The image shows a portion of the cross-sectional view of the display device DD taken by line I-I'. For ease of description, Figure 5B The window module WM is omitted in the reference. Figure 3 ) and input sensing layer ISL (reference) Figure 3 The specific configuration of ).
[0134] refer to Figure 5A and Figure 5B The display element layer DP-ED may include a pixel defining layer PDL defined therein by a pixel opening OH and a light-emitting element ED-1 disposed in the pixel opening OH. The pixel opening OH may overlap with the light-emitting region LA. The light-emitting element ED-1 may include a first electrode EL1, a second electrode EL2, a hole transport layer HTR disposed between the first electrode EL1 and the second electrode EL2, a light-emitting layer EML-R and an electron transport layer ETR, and a capping layer CPL disposed on the second electrode EL2. Further reference Figure 5C The display element layer DP-ED may further include light-emitting elements ED-2 and ED-3. Light-emitting element ED-2 may include a first electrode EL1, a second electrode EL2, a hole transport layer HTR disposed between the first electrode EL1 and the second electrode EL2, a light-emitting layer EML-G, an electron transport layer ETR, and a capping layer CPL disposed on the second electrode EL2. Light-emitting element ED-3 may include a first electrode EL1, a second electrode EL2, a hole transport layer HTR disposed between the first electrode EL1 and the second electrode EL2, a light-emitting layer EML-B, an electron transport layer ETR, and a capping layer CPL disposed on the second electrode EL2. Therefore, the light-emitting element OLED may include a first electrode EL1, a second electrode EL2, a hole transport layer HTR disposed between the first electrode EL1 and the second electrode EL2, a light-emitting layer EML and an electron transport layer ETR, and a capping layer CPL disposed on the second electrode EL2.
[0135] The first electrode EL1 can be exposed by the pixel opening OH. The area where the first electrode EL1 is exposed by the pixel opening OH can be defined as the light-emitting area LA (reference). Figure 4 ).
[0136] A light control layer CCL can be disposed on the display panel DP. In this disclosure, the light control layer CCL may include multiple layers. When the light control layer CCL comprises a single layer, the effect of adjusting the viewing angle through the light control layer CCL may be reduced. When the light control layer CCL comprises multiple layers, the thickness of the display device DD may be increased, and manufacturing costs may be increased. In this manner, it is advantageous to include at least two but less than or equal to five light control layers CCL.
[0137] In this embodiment, Figures 5A to 5C As depicted, four light control layers, CCL1, CCL2, CCL3, and CCL4, can be provided. The light control layers CCL1, CCL2, CCL3, and CCL4 can be stacked sequentially in a direction away from the display panel DP. The light control layers CCL1, CCL2, CCL3, and CCL4 can be arranged sequentially on a third-direction DR3.
[0138] The first light control layer CCL1 may include a first light-blocking pattern BM1 and a first insulating layer IL1. The second light control layer CCL2 may include a second light-blocking pattern BM2 and a second insulating layer IL2. The third light control layer CCL3 may include a third light-blocking pattern BM3 and a third insulating layer IL3. The fourth light control layer CCL4 may include a fourth light-blocking pattern BM4 and a fourth insulating layer IL4. In some examples, the display device DD may include five light control layers.
[0139] The first light-blocking pattern BM1 may include an extension PT1 and a connecting portion PT2. However, for ease of description, the extension PT1 and the connecting portion PT2 are distinguished from each other, and the first light-blocking pattern BM1 may be provided as a continuous body. The extension PT1 and the connecting portion PT2 may be formed together in one process, for example, they may be formed simultaneously and may include the same material.
[0140] Each of the extensions PT1 may have an elongated dimension extending in the first direction DR1 to overlap with the light-emitting region LA and the non-light-emitting region NLA, and the extensions PT1 may be arranged such that each extension PT1 is spaced apart in the second direction DR2. The extensions PT1 may be spaced apart from each other in the second direction DR2 at a predetermined interval L-PT1. Figure 5A An example is shown where five extensions PT1 are provided in the display device DD.
[0141] At least one connecting portion PT2 may be disposed between two adjacent extensions PT1, that is, between a pair of adjacent extensions. The connecting portion PT2 may be configured to overlap with the non-emitting region NLA but not with the emitting region LA. Therefore, two adjacent extensions PT1 can be connected by the connecting portion PT2. Each of the plurality of connecting portions PT2 may be directly connected to two extensions PT1. Throughout this disclosure, "connecting portion PT2" may also be referred to as "connecting pattern PT2".
[0142] In this embodiment, the connecting portion PT2 may extend in the second direction DR2. The connecting portions PT2 may be spaced apart from each other in the first direction DR1 by a predetermined interval L-PT2. The interval L-PT2 may be greater than the "minimum light-emitting area width". The "minimum light-emitting area width" may refer to the minimum width of each of the first light-emitting areas LA1-1 to the third light-emitting areas LA3-2 in the first direction DR1.
[0143] The angle between the extending direction of the connecting part PT2 (i.e., the direction in which the elongated dimension extends) and the first direction DR1 can be defined as the "connecting angle AG". Although Figure 5A An example with a connection angle AG of 90 degrees is shown, but the embodiments disclosed herein are not limited to those shown. Figure 5A The connecting angle AG is shown in the figure. For example, the extending direction of the connecting part PT2 may be transverse to the extending direction of the extending part PT1, for example, at an acute angle or at an oblique angle.
[0144] The light-blocking patterns in related technologies only include connecting portions in the form of "parallel lines" that extend in one direction and are spaced apart from each other in directions intersecting said one direction, or as will be referred to below. Figure 6A As described herein, it includes a portion extending in one direction and a "mesh-shaped" connecting portion extending in a direction intersecting said one direction.
[0145] However, such arrangements are prone to defects or failures. For example, in the case of a light-blocking pattern arranged in the form of "parallel lines," adjacent connecting parts may not be fixed to each other, and therefore some of the connecting parts may detach during the manufacturing process. Furthermore, in the case of "mesh-shaped" connecting parts, adjacent connecting parts can be firmly fixed to each other, but this arrangement is subject to heavy (i.e., high) manufacturing costs, and the use of such "mesh-shaped" connecting parts results in an undesirable reduction in the visibility of the display device.
[0146] The display device DD according to this disclosure may include an extension PT1 having a corresponding elongated or long dimension extending in a first direction DR1, and thus can reduce the cost required for the manufacturing process. Furthermore, the display device DD according to this disclosure may include a connecting portion PT2 disposed between adjacent extensions PT1, and thus, such a connecting portion PT2 can effectively prevent some of the extensions PT2 from detaching. That is, each of the plurality of extensions PT1 according to this disclosure can be connected to its adjacent extension PT1 via the connecting portion PT2, and thus can be firmly fixed in the manufacturing process without detaching. Furthermore, with manufacturing to have such Figure 6A The "mesh-shaped" connecting parts of the structure shown are different. For example, the connecting part PT2 is smaller in size than the extension part PT1, which can reduce manufacturing costs and prevent the brightness of the display device DD from decreasing. In this document, "elongated dimension" or "long dimension" can be understood as the long side of an object.
[0147] Although for ease of description in Figure 5B and Figure 5C The input sensing layer (ISL) is omitted (see reference). Figure 3 ), but the input sensing layer ISL (reference) Figure 3 This may include conductive patterns. The input sensing layer ISL (reference) Figure 3 The contact between a user or object and the display device DD can be detected by sensing changes in the electrical signal. In this case, the first light-blocking pattern BM1 can be set on the input sensing layer ISL (see reference). Figure 3 ).
[0148] The display device DD according to an embodiment may further include an "inorganic protective film". The inorganic protective film may be disposed on the bottom of the first light-blocking pattern BM1. The inorganic protective film may perform the function of protecting the bottom of the first light-blocking pattern BM1 and may improve the adhesion of the bottom of the first light-blocking pattern BM1.
[0149] refer to Figure 5A and Figure 5B When viewed from above the plane (i.e., on the third-direction DR3), at least a portion of each extension PT1 can overlap with the light-emitting region LA. A portion of the extension PT1 can overlap with the light-emitting region LA, and the remaining portion of the extension PT1, excluding that portion, can not overlap with the light-emitting region LA.
[0150] Figure 5AAn example is shown where the four extensions PT1 completely overlap with the first light-emitting region LA1, the second light-emitting region LA2, and the third light-emitting region LA3. However, embodiments of this disclosure are not limited thereto, and the extensions PT1 may overlap with some of the first light-emitting regions LA1, the second light-emitting region LA2, and the third light-emitting region LA3. For example, the extensions PT1 may overlap with the first-first light-emitting region LA1-1, the second-first light-emitting region LA2-1, and the third-first light-emitting region LA3-1, but may not overlap with the first-second light-emitting region LA1-2, the second-second light-emitting region LA2-2, and the third-second light-emitting region LA3-2. In this case, the display device DD according to this disclosure may further include a light-blocking barrier F-BM (refer to) adjacent to the first-second light-emitting region LA1-2, the second-second light-emitting region LA2-2, and the third-second light-emitting region LA3-2. Figure 11B Its description will be given later.
[0151] The connecting portion PT2 may not overlap with the light-emitting region LA. Since the connecting portion PT2 has a relatively small planar area compared to the extension portion PT1, the connecting portion PT2 can be selectively disposed in the non-light-emitting region NLA. Figure 5A and Figure 5C An example is shown where the connecting portion PT2 does not overlap with the light-emitting regions LA1-2, LA2-2, and LA3-2, but only with the non-light-emitting region NLA. Therefore, the display device DD including the connecting portion PT2 according to embodiments of this disclosure can prevent a decrease in brightness.
[0152] The connecting portions PT2 disposed between adjacent extensions PT1 can be spaced apart from each other, such that at least one of the light-emitting regions LA is disposed between the connecting portions PT2. However, embodiments of this disclosure are not limited thereto. For example, and as... Figure 11A and Figure 11B As shown, for example, the extension PT1 can be arranged such that this extension PT1 is not located between the first-second light-emitting region LA1-2, the second-second light-emitting region LA2-2, and the third-second light-emitting region LA3-2. In this case, the display device DD according to the present disclosure may further include a light-blocking barrier F-BM (reference) adjacent to the first-second light-emitting region LA1-2, the second-second light-emitting region LA2-2, and the third-second light-emitting region LA3-2. Figure 11B Its description will be given below.
[0153] In this embodiment, and continuing to refer to Figures 5A to 5CA connecting portion PT2 adjacent to one of the connecting portions PT2 and also positioned relative to that connecting portion PT2 in the "downward direction" can also be positioned relative to that connecting portion PT2 in the "rightward direction". However, the embodiments of this disclosure are not limited to the embodiments shown in the accompanying drawings. For example, a connecting portion PT2 positioned relative to any one of the connecting portions PT2 in the "downward direction" can also be positioned relative to any one of the connecting portions PT2 in the "leftward direction".
[0154] Figure 6A This is a plan view showing a partial area of the display device according to the comparative example. Figure 6B This is a plan view showing a partial area of a display device according to an embodiment of the present disclosure. Figure 6C This is a schematic diagram illustrating different observation areas (i.e., the range of angles within the field of view) according to this disclosure.
[0155] refer to Figure 6A According to the comparative example, the display device DD' may include a first light-emitting area LA1, a second light-emitting area LA2 and a third light-emitting area LA3, and a first light-blocking pattern BM1' including a portion extending in one direction and a "mesh-shaped" connecting portion extending in a direction intersecting the one direction.
[0156] refer to Figure 6B The display device according to Embodiment 1 may include a connecting portion PT2 (see reference) disposed in region A1'. Figure 5A According to embodiment 2, the display device may include a connecting portion PT2 disposed in region A2' (see reference). Figure 5A Furthermore, the display device according to embodiment 3 may include a connecting portion PT2 disposed in region A3' (see reference). Figure 5A ).
[0157] Table 1 shows the "brightness reduction amount" of corresponding areas of the display device DD' according to the comparative example and the display device DD according to Embodiments 1 to 3. Areas 1 to 3 of Table 1 are quantitative measurements of the brightness reduction amount in predetermined areas when observing the display device DD' according to the comparative example and the display device DD according to Embodiments 1 to 3.
[0158] refer to Figure 6C In Table 1, "Region 1 ZN1" can refer to a region having an angle of -10° to +10° in the horizontal direction and an angle of -4° to +8° in the vertical direction. "Region 2 ZN2" can refer to a region having an angle of -40° to +40° in the horizontal direction and an angle of -10° to +20° in the vertical direction. "Region 3 ZN3" can refer to a region having an angle of -50° to +50° in the horizontal direction and an angle of -10° to +20° in the vertical direction.
[0159] [Table 1]
[0160] In the display device DD' according to the comparative example and the display device DD according to Embodiments 1 to 3, the brightness at an angle of 35° relative to the vertical direction can be 5% or less of the brightness at an angle of 0° relative to the front direction. Referring to Table 1, it can be seen that in the display device DD' according to the comparative example and the display device DD according to Embodiments 1 to 3, the brightness at an angle of 35° relative to the vertical direction is 1.3% of the brightness at an angle of 0° relative to the front direction. In Table 1, "percentage of front obstruction" can refer to the luminous area LA (reference) when the display device is viewed from the front / rear. Figure 5A The percentage of light obstruction by the light-blocking pattern. "Front obstruction percentage" is only affected by the extension PT1 (reference). Figure 5A It is unaffected by the connection part PT2 (reference). Figure 5A The effect of this. Therefore, in the comparative example and embodiments 1 to 3 of this disclosure, the front blocking percentage can have the same value of 60%.
[0161] Referring to Table 1, it can be seen that the percentage reduction in brightness in regions 1 to 3 of Examples 1 to 3 ranges from a minimum of 0% to a maximum of 1.6%. That is, according to this disclosure, it can be confirmed that the amount of brightness reduction in Examples 1 to 3 is equal to or less than the amount of brightness reduction in the comparative examples, regardless of the connecting part PT2 (reference). Figure 5A The setting is in region A1', region A2', or region A3'.
[0162] In other words, these results confirm that, according to the display device DD (reference DD) of this disclosure... Figure 5A (Including the connecting part PT2 located in a position that does not overlap with the light-emitting area (reference)) Figure 5A It is effective in minimizing the amount of brightness reduction.
[0163] In the following description, various embodiments of a display device according to the present disclosure will be described with reference to the accompanying drawings.

[0166] Figure 7 The arrangement of the luminescent region LA and the first light-blocking pattern BM1-1a, as well as the relationship between the luminescent region LA and the first light-blocking pattern BM1-1a, are shown.
[0167] In the display device DD-1a according to the embodiment, the connecting portion PT2' may be outside the light-emitting area LA and not overlap with the light-emitting area LA, and at least one connecting portion PT2' may be disposed between two adjacent extension portions PT1.
[0168] However, the connecting part PT2' can be randomly positioned along the first direction DR1 at a location that does not overlap with the light-emitting area LA. Therefore, the connecting part PT2' is positioned in the display area DA (reference). Figure 3 The positions in the first direction DR1 can be dispersed rather than clustered at a specific location.

[0171] In the display device DD-1b according to an embodiment, the first light-blocking pattern BM1-1b may include an extension PT1 and a second extended connecting portion PE2-2. Throughout this disclosure, "extended connecting portion" may correspond to a connecting portion that allows adjacent extensions PT1 to be continuously connected. Figure 8 In this configuration, each of the plurality of second extension connecting portions PE2-2 includes a first extension connecting portion PT2a, a second extension connecting portion PT2b, and a third extension connecting portion PT2c arranged side-by-side in the second direction DR2 to connect four adjacent extension portions PT1. For example... Figure 8 The second extended connection PE2-2 shown in the figure is illustrated as an example.
[0172] However, the type of extension connection is not limited to this. For example, it may include an assembly containing two extension connections arranged side by side on the second direction DR2 to connect three adjacent extensions PT1, and this assembly may be defined as a "first extension connection" (e.g., Figure 15 The first extended connection part PE2-1 shown in the figure. Its description will be given later.
[0173] refer to Figure 8 The second extended connection PE2-2 can be spaced apart from each other at a predetermined interval W-PT2 in the first direction DR1.

For example, the interval W-PT2 can be greater than or equal to one unit spacing W-PU and less than or equal to five unit spacing W-PU. In other examples, the interval W-PT2 can be greater than or equal to one unit spacing W-PU and less than or equal to four unit spacing W-PU.

The following description will focus on references to... Figures 3 to 5C Differences in the implementation examples.
[0177] Figure 9 It is a view showing the arrangement of the light-emitting area LA and the first light-blocking pattern BM1-2, as well as the relationship between the light-emitting area LA and the first light-blocking pattern BM1-2.
[0178] The connecting portion PT2-L may not overlap with the light-emitting area LA (i.e., it may be completely outside the light-emitting area LA), and at least one connecting portion PT2-L may be disposed between two adjacent extensions PT1.
[0179] Throughout this disclosure, the extending direction of the connecting portion PT2-L (i.e., the direction in which the elongation dimension extends) can be defined as the "connecting direction DRc". The angle at which the first direction DR1 and the connecting direction DRc intersect each other can be defined as the "connecting angle AG".
[0180] In this embodiment, the connection direction DRc can be the direction between the first direction DR1 and the second direction DR2. Therefore, the connection angle AG can be an acute angle or an obtuse angle. Figure 9 An example of an acute angle AG is shown. However, embodiments of this disclosure are not limited to those shown in the figures, and the connection angle AG may be obtuse according to other examples.

[0182] Reference Figures 3 to 5C Components that are the same as or similar to the described components will be Figure 10A and Figure 10B Reference numerals are assigned the same or similar designations, and repeated descriptions will be omitted. The following description will focus on references to... Figures 3 to 5C Differences in the implementation examples.
[0183] In this embodiment, the extension PT1 and the extension connector PT2-D may not overlap with the light-emitting region LA. The extension PT1 and the extension connector PT2-D may not block the light emitted from the light-emitting region LA. When viewed from above a plane coinciding with the first direction DR1 and the second direction DR2 (i.e., viewed from the third direction DR3), the extension PT1 and the extension connector PT2-D may be disposed in the non-light-emitting region NLA.
[0184] The spacing between the extensions PT1 included in the display device DD-3 in the second direction DR2 can be greater than that of the display device DD (reference). Figure 5A The extension PT1 included in the ) (refer to Figure 5A The interval L-PT1 between (reference) Figure 5A ).
[0185] In the display device DD-3 according to this embodiment, the light emitted from the light-emitting region LA is not blocked by the extension PT1 and the extension connecting portion PT2-D. Therefore, compared to an arrangement where the connecting portion blocks at least some of the light-emitting region, the brightness of the light emitted by the display device DD-3 can be increased.
[0186] refer to Figure 10B The input sensing layer ISL may include a first sensing conductive pattern YMTL1, a first sensing insulating layer YCNT covering the first sensing conductive pattern YMTL1, and a second sensing conductive pattern YMTL2 disposed on the first sensing insulating layer YCNT.
[0187] In this arrangement, the shape of the first light-blocking pattern BM1 can be modified to correspond to the shape of the sensing conductive pattern covered by the first light-blocking pattern BM1. Figure 10B An example is shown where the shape of the first light-blocking pattern BM1 is modified to correspond to the shape of the second sensing conductive pattern YMTL2.

[0189] Reference Figures 3 to 5C Components that are the same as or similar to the described components will be Figure 11A and Figure 11B Reference numerals are assigned the same or similar designations, and repeated descriptions will be omitted. The following description will focus on references to... Figures 3 to 5C Differences in the implementation examples.
[0190] The display device DD-4a according to this embodiment may further include a light-blocking barrier F-BM. The light-blocking barrier F-BM may be disposed on the encapsulation layer TFE. The light-blocking barrier F-BM may be disposed adjacent to the first-second light-emitting region LA1-2, the second-second light-emitting region LA2-2, and the third-second light-emitting region LA3-2. When viewed from above the plane (i.e., on the third-direction DR3), the light-blocking barrier F-BM according to this embodiment may have a shape surrounding the first-second light-emitting region LA1-2, the second-second light-emitting region LA2-2, and the third-second light-emitting region LA3-2.
[0191] Therefore, the light-blocking barrier F-BM can perform the function of reducing the viewing angle of light emitted from the first-second emitting region LA1-2, the second-second emitting region LA2-2, and the third-second emitting region LA3-2.
[0192] According to this disclosure, the display device DD-4a can limit the wide viewing angle of the first-first light-emitting area LA1-1, the second-first light-emitting area LA2-1, and the third-first light-emitting area LA3-1 in the vertical direction through the first extension PT1. That is, the first extension PT1 can perform the function of limiting the wide viewing angle of the "first type of light-emitting element" in the vertical direction.
[0193] Furthermore, the display device DD-4a according to this disclosure may include a light-blocking barrier F-BM, and may perform the function of limiting a wide viewing angle in the up, down, left, and right directions. In other words, the light-blocking barrier F-BM may perform the function of limiting the wide viewing angle of the "second type of light-emitting element" in the up and down directions.
[0194] When the display device DD-4a according to this disclosure operates in the "first mode," only the "first type of light-emitting element" can be driven. Light emitted from the "first type of light-emitting element" can be partially blocked by the first light-blocking pattern BM1, and thus the wide viewing angle in the vertical direction can be limited. Alternatively, both the "first type of light-emitting element" and the "second type of light-emitting element" can be driven. Light emitted from the "first type of light-emitting element" can be partially blocked by the first light-blocking pattern BM1, and thus the wide viewing angle in the vertical direction can be limited. Light emitted from the "second type of light-emitting element" can be partially blocked by the first light-blocking barrier F-BM1, and thus the wide viewing angle in the upward, downward, leftward, and rightward directions can be limited.
[0195] When the display device DD-4a according to this disclosure is operated in "second mode", only the "second type of light-emitting element" can be driven. Therefore, the light emitted from the "second type of light-emitting element" can be partially blocked by the first light-blocking barrier F-BM1, and thus the wide viewing angle in the upward, downward, leftward and rightward directions can be limited.
[0196] refer to Figure 11B The first light-blocking barrier F-BM1, the second light-blocking barrier F-BM2, the third light-blocking barrier F-BM3, and the fourth light-blocking barrier F-BM4 can be stacked sequentially on the third-direction DR3. When viewed from above the plane (i.e., when viewed on the third-direction DR3), the first light-blocking barrier F-BM1, the second light-blocking barrier F-BM2, the third light-blocking barrier F-BM3, and the fourth light-blocking barrier F-BM4 can overlap each other.
[0197] The first light-blocking barrier F-BM1, the second light-blocking barrier F-BM2, the third light-blocking barrier F-BM3, and the fourth light-blocking barrier F-BM4 can be used in conjunction with the first light-blocking pattern BM1 (see reference). Figure 10B ), second light-blocking pattern BM2 (reference) Figure 10B ), third light-blocking pattern BM3 (reference) Figure 10B ) and the fourth light-blocking pattern BM4 (reference) Figure 10B It is formed using the same process and can be combined with the first light-blocking pattern BM1 (reference). Figure 10B ), second light-blocking pattern BM2 (reference) Figure 10B ), third light-blocking pattern BM3 (reference) Figure 10B ) and the fourth light-blocking pattern BM4 (reference) Figure 10B (These include the same materials.) In some examples, the light-blocking barrier can be formed together with a light-blocking pattern.

[0200] refer to Figure 12 The display device DD-4b according to this embodiment may include a first extension pattern (including extension portion PT1), a second connection pattern (including connection portion PT2), and a first light blocking barrier F-BM1'.
[0201] When viewed from above the plane (i.e., on the third-direction DR3), the first light-blocking barrier F-BM1' according to this embodiment may have a shape that partially surrounds the first-second light-emitting region LA1-2, the second-second light-emitting region LA2-2, and the third-second light-emitting region LA3-2. Figure 12 An example is shown where the first light-blocking barrier F-BM1' does not surround the lower portion of the first-second luminous region LA1-2, the second-second luminous region LA2-2, and the third-second luminous region LA3-2.
[0202] Therefore, the first light-blocking barrier F-BM1' can not block the light emitted in the downward direction from the light emitted from the first-second light-emitting region LA1-2, the second-second light-emitting region LA2-2, and the third-second light-emitting region LA3-2.

[0211] The third luminescent region LA3' can have a larger planar area than the first luminescent region LA1' and the second luminescent region LA2'. For example... Figure 14 As shown, the planar area can be the area in a plane perpendicular to the third direction DR3. The planar area of the emitting region may also be referred to as the emission surface area in this paper.

However, this is only for ease of description, and the extension PT1, the connecting portion PT2, and the first extended connecting portion PE2-1 may be provided integrally.

The first extension connector PE2-1 can overlap with at least a portion of the extension PT1, and the extension PT1 can overlap with the third light-emitting region LA3'. The first extension connector PE2-1 can perform the function of connecting three to five adjacent extensions PT1.
[0214] The first extended connector PE2-1 may include a plurality of extended connectors PT2a and PT2b arranged side by side along the second direction DR2 so as to be adjacent to each other. The number of extended connectors PT2a and PT2b may be one less than the number of extended connectors PT1 connected by the first extended connector PE2-1.

That is, because the first external connection part PT2-1s is set not to connect with the display area DA (reference) Figure 16 and Figure 17 Because the first external connection part PT2-1s overlaps with all extension parts PT1, the display device DD-6 according to this embodiment can fundamentally prevent the brightness reduction caused by the first external connection part PT2-1s. Furthermore, since the first external connection part PT2-1s is connected to all extension parts PT1, the detachment of the extension parts PT1 can be effectively reduced.
