[0049] In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various exemplary embodiments or implementations of the invention. As used herein, "embodiment" and "implementation" are interchangeable words that are non-limiting examples of a device or method that employs one or more of the inventive concepts disclosed herein. However, it is apparent that the various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. In other instances, well-known structures and devices are shown in block diagram form in order not to unnecessarily obscure the various exemplary embodiments. Additionally, the various exemplary embodiments may be different, but not necessarily exclusive. For example, without departing from the inventive concept, the specific shapes, configurations, and features of an exemplary embodiment may be used or implemented in another exemplary embodiment.

[0050] Unless otherwise specified, the exemplary embodiments shown are understood to provide exemplary features of details of variations in some ways in which the inventive concept may be implemented in practice. Accordingly, unless otherwise specified, the features, components, modules, layers, films, panels, regions, and / or aspects, etc. (collectively referred to as "elements" hereinafter) of the various embodiments may be additionally combined, separated, interchanged, and / or rearranged without departing from the inventive concept.

[0051] The use of cross-hatching and / or shading is typically provided in the drawings to clarify the boundaries between adjacent elements. Thus, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or imply any preference or requirement regarding the specific material, material properties, dimensions, proportions, commonality between the elements shown, and / or any other characteristics, attributes, properties, etc. of the elements. Additionally, in the drawings, for clarity and / or descriptive purposes, the dimensions and relative dimensions of elements may be exaggerated. When the exemplary embodiments can be implemented differently, the specific process sequences may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in an order opposite to that described. Additionally, the same reference numerals represent the same elements.

[0052] When an element (such as a layer) is referred to as being "on", "connected to", or "coupled to" another element or layer, the element (such as a layer) can be directly on the other element or layer, directly connected to, or directly coupled to the other element or layer, or there can be intervening elements or layers. However, when an element or layer is referred to as being "directly on", "directly connected to", or "directly coupled to" another element or layer, there are no intervening elements or layers. For this reason, the term "connected" can refer to a physical connection, an electrical connection, and / or a fluid connection, with or without intervening elements. Additionally, the D1 axis, D2 axis, and D3 axis are not limited to the three axes of a rectangular coordinate system (such as the x-axis, y-axis, and z-axis), but can be interpreted in a broader sense. For example, the D1 axis, D2 axis, and D3 axis can be perpendicular to each other, or can represent different directions that are not perpendicular to each other. For the purposes of this disclosure, "at least one of X, Y, and Z" and "at least one selected from the group consisting of X, Y, and Z" can be interpreted as only X, only Y, only Z, or any combination of two or more of X, Y, and Z, such as by way of example XYZ, XYY, YZ, and ZZ. As used herein, the term "and / or" includes any combination and all combinations of one or more of the associated listed items.

[0053] Although the terms "first", "second", etc. may be used herein to describe various types of elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another. Thus, without departing from the teachings of the disclosure, the first element discussed below could be termed the second element.

[0054] For descriptive purposes, spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on top of", "higher", "side" (e.g., as in "sidewall") may be used herein to describe the relationship of one element to another (additional) element as illustrated in the figures. The spatial relative terms are intended to include different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "under" or "beneath" other elements or features will then be oriented "above" the other elements or features. Thus, the exemplary term "under" can include both an orientation of above and below. Additionally, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and as such, the corresponding spatial relative descriptors used herein are to be interpreted accordingly.

[0055] The terms used herein are for the purpose of describing particular embodiments and are not intended to be limiting. As used herein, unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" are also intended to include the plural forms. Additionally, when the terms "comprises", "comprising", and / or their variants are used in this specification, it is specified that there are the stated features, integers, steps, operations, elements, components, and / or groups thereof, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof. It is also noted that, as used herein, the terms "substantially", "about", and other similar terms are used as terms of approximation and not of degree, and as such, are used to interpret the inherent deviations of measured, calculated, and / or provided values that would be recognized by one of ordinary skill in the art.

[0056] Various exemplary embodiments are described herein with reference to cross-sectional views and / or exploded views that are schematic illustrations of idealized exemplary embodiments and / or intermediate structures. As such, variations in the illustrated shapes are to be expected due to, for example, manufacturing techniques and / or tolerances. Thus, the exemplary embodiments disclosed herein are not necessarily to be construed as limited to the particular shapes of the regions shown, but include deviations in shapes resulting from, for example, manufacturing. In this manner, the regions shown in the figures are essentially schematic, and the shapes of these regions may not reflect the actual shape of the regions of the device, and as such, are not necessarily intended to be limiting.

[0057] As is customary in the art, some exemplary embodiments are described and illustrated in the drawings in the form of functional blocks, units, and / or modules. Those skilled in the art will understand that these blocks, units, and / or modules are physically implemented by electronic (or optical) circuits such as logic circuits, discrete components, microprocessors, hardwired circuits, memory elements, wiring connections, etc., and the circuits can be formed using semiconductor-based manufacturing technologies or other manufacturing technologies. In the case where the blocks, units, and / or modules are implemented by a microprocessor or similar hardware, the blocks, units, and / or modules can be programmed and controlled using software (e.g., microcode) to perform the various functions discussed herein, and can optionally be driven by firmware and / or software. It is also contemplated that each block, unit, and / or module can be implemented by dedicated hardware or as a combination of dedicated hardware that performs some functions and a processor (e.g., one or more programmed microprocessors and associated circuits) that performs other functions. Additionally, without departing from the scope of the inventive concept, each block, unit, and / or module of some exemplary embodiments can be physically divided into two or more interacting and discrete blocks, units, and / or modules. Further, without departing from the scope of the inventive concept, the blocks, units, and / or modules of some exemplary embodiments can be physically combined into more complex blocks, units, and / or modules.

[0058] 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 belongs. Terms (such as those defined in a general dictionary) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0059] Figure 1A is a combined perspective view showing an electronic device according to an exemplary embodiment of the inventive concept, Figure 1B is an exploded perspective view showing an electronic device according to an exemplary embodiment of the inventive concept. Figure 2 is showing Figure 1B an exploded perspective view of some of the components shown in. Hereinafter, reference will be made to Figure 1A 、 Figure 1B and Figure 2 to describe exemplary embodiments of the inventive concept.

[0060] In a planar view defined by a first direction D1 and a second direction D2, an electronic device EA displays an image IM in a third direction D3. The electronic device EA includes a window member 100, a display module 200, an electronic module 300, and a housing member 400. In an exemplary embodiment, the window member 100, the display module 200, and the electronic module 300 can be combined with each other to form a display unit DU.

[0061] The window member 100 is disposed on the display module 200 to cover the front surface IS of the display module 200. The window member 100 includes a base panel BP, a first light-shielding pattern BR1, a second light-shielding pattern BR2, and a perforated plate WP. The base panel BP may be optically transparent. For example, the base panel BP may include glass or plastic. The base panel BP may have a single-layer or multi-layer structure. For example, the base panel BP may have a laminated structure in which a plurality of plastic films are bonded by an adhesive or a laminated structure in which a glass substrate and a plastic film are bonded by an adhesive.

[0062] The window member 100 includes a front surface FS that is exposed to the outside. The image IM displayed on the display module 200 is externally visible through the front surface FS. The front surface FS of the window member 100 may be divided into a transmissive region TA and a border region BZA in a plan view.

[0063] The transmissive region TA may be a region through which incident light is transmitted. The transmissive region TA may have a shape corresponding to the active region AA. For example, the transmissive region TA overlaps with the front surface of the active region AA or at least a part of the active region AA. The image IM displayed on the active region AA of the display module 200 can be externally seen through the transmissive region TA.

[0064] The border region BZA may have a light transmittance relatively lower than that of the transmissive region TA. The border region BZA defines the shape of the transmissive region TA. The border region BZA may be disposed adjacent to the transmissive region TA to surround the transmissive region TA.

[0065] The border region BZA may have a predetermined color. The border region BZA may cover the peripheral region NAA of the display module 200 to prevent the peripheral region NAA from being externally seen. However, the exemplary embodiments of the inventive concept are not limited thereto. For example, the border region BZA according to the exemplary embodiments of the inventive concept may be omitted from the window member 100.

[0066] In a plan view, each of the first hole region HA1 and the second hole region HA2 may overlap with the electronic module 300 to be described later. The electronic module 300 may operate by receiving external signals provided through the first hole region HA1 and the second hole region HA2.

[0067] In an exemplary embodiment, a first hole region HA1 is defined in a transmissive region TA, and a second hole region HA2 is defined in a border region BZA. However, the exemplary embodiments of the inventive concept are not limited thereto. For example, the first hole region HA1 and the second hole region HA2 may be defined in regions opposite to each other, respectively. Alternatively, both the first hole region HA1 and the second hole region HA2 may be defined in the transmissive region TA or in the border region BZA. Additionally, one of the first hole region HA1 and the second hole region HA2 may be omitted.

[0068] However, the exemplary embodiments of the inventive concept are not limited thereto. For example, the window member 100 may include various exemplary embodiments.

[0069] A predetermined recessed portion recessed from the rear surface of the base panel BP may be defined in each of the first hole region HA1 and the second hole region HA2. The recessed portion may include a groove having a depth less than the thickness of the base panel BP and a through hole having the same depth as the thickness of the base panel BP. In an embodiment, the through hole is exemplarily defined in the base panel BP.

[0070] A first hole HH1 is defined in the first hole region HA1, and a second hole HH2 is defined in the second hole region HA2. Accordingly, the first hole HH1 may be defined in the transmissive region TA, and the second hole HH2 may be defined in the border region BZA.

[0071] In an exemplary embodiment, the first hole HH1 and the second hole HH2 may have different shapes from each other. For example, the first hole HH1 may have a circular shape, and the second hole HH2 may have an oval shape having a major axis extending in a first direction D1. Each of the first hole HH1 and the second hole HH2 may have a shape corresponding to the shape of the stacked components of the electronic module 300. Accordingly, each of the first hole HH1 and the second hole HH2 may have various shapes and sizes. However, the exemplary embodiments of the inventive concept are not limited thereto.

[0072] A hole plate WP may be inserted into the hole defined in the base panel BP. In an exemplary embodiment, the hole plate WP is disposed in the first hole HH1. Accordingly, the hole plate WP has a circular shape corresponding to the shape of the first hole HH1. However, the exemplary embodiments of the inventive concept are not limited thereto. For example, the hole plate WP according to the exemplary embodiments of the inventive concept may have a shape corresponding to the shape of the second hole HH2 and be disposed in the second hole HH2. Additionally, the hole plate WP may be omitted from the electronic device EA according to the exemplary embodiments of the inventive concept.

[0073] The first light-shielding pattern BR1 covers the inner surface of the first hole HH1. The first light-shielding pattern BR1 may have an annular shape corresponding to the shape of the first hole HH1. The first light-shielding pattern BR1 and the aperture plate WP may be inserted together into the first hole HH1. The first light-shielding pattern BR1 may fill the space between the circumference of the aperture plate WP and the inner surface of the first hole HH1.

[0074] The first light-shielding pattern BR1 may have adhesiveness. Thus, the first light-shielding pattern BR1 may physically bond the aperture plate WP to the substrate panel BP. The first light-shielding pattern BR1 may have a color with high light-shielding properties. For example, the first light-shielding pattern BR1 may have a black color or a color with a high light absorption rate.

[0075] The second light-shielding pattern BR2 covers the inner surface of the second hole HH2. The second light-shielding pattern BR2 may have an elliptical annular shape corresponding to the shape of the second hole HH2. In an embodiment, different from the first hole HH1, no additional component such as the aperture plate WP may be inserted into the second hole HH2. Thus, the second light-shielding pattern BR2 may be exposed to the outside. The second light-shielding pattern BR2 may contain a material with high light-shielding properties. The inner surface of the second hole HH2 may be substantially coated with the second light-shielding pattern BR2 in a light-shielding manner.

[0076] The display module 200 displays an image IM on the front surface IS. The front surface IS may be divided into an active area AA and a peripheral area NAA. The image IM is displayed on the active area AA. The peripheral area NAA is disposed adjacent to the active area AA.

[0077] The display module 200 may include a plurality of pixels PX. The pixels PX display light in response to an electrical signal. The light displayed by the pixels PX realizes the image IM.

[0078] In an embodiment, a predetermined through-hole passing through the display module 200 may be defined in the display module 200. The module hole MH may be defined in the active area AA of the display module 200.

[0079] The module hole MH overlaps with the first hole area HA1. The module hole MH is defined in the active area AA. Thus, some pixels PX may be arranged around the module hole MH. The image IM is displayed in an area disposed adjacent to the module hole MH.

[0080] The electronic module 300 includes various functional modules for operating the electronic device EA. The electronic module 300 may be electrically connected to the display module 200 through a connector (not shown). For example, the electronic module 300 may include a camera, a speaker, or a sensor for detecting light or heat.

[0081] For example, the electronic module 300 may include a first electronic module 310 and a second electronic module 320. The first electronic module 310 may detect an external object received through the module hole MH and the first hole region HA1. The first electronic module 310 may receive an external input transmitted through the module hole MH and the first hole region HA1, or provide an output through the module hole MH and the first hole region HA1.

[0082] For example, the first electronic module 310 may be one of a light-emitting module, a light-detecting module, and a photographing module. For example, the first electronic module 310 may include at least one of a light-emitting module that emits infrared rays, a CMOS sensor for detecting infrared rays, and a camera module for photographing an external object.

[0083] The second electronic module 320 may collect a sound signal such as voice through the second hole region HA2, or provide a sound signal such as processed voice to the outside. For example, the second electronic module 320 may include at least one of a sound input module and a sound output module. The sound input module may include a microphone capable of receiving a sound signal. The sound output module may include a speaker that outputs sound data as a sound signal.

[0084] However, the exemplary embodiments of the inventive concept are not limited thereto. For example, the electronic module 300 may include a single module and further include a greater number of electronic modules, and the electronic modules may be arranged in various arrangement relationships.

[0085] The housing member 400 is disposed below the display module 200. The housing member 400 may be coupled to the window member 100 to provide an outer shape of the electronic device EA. The housing member 400 may include a material having relatively high rigidity. For example, the housing member 400 may include a plurality of frames and / or plates made of glass, plastic, and / or metal.

[0086] The housing member 400 provides a predetermined accommodation space. The display module 200 and the electronic module 300 may be accommodated in the accommodation space and protected from external impacts.

[0087] According to an exemplary embodiment of the inventive concept, a part of the electronic module 300 may overlap with the active area AA of the display module 200 and the transmission area TA of the window member 100. Accordingly, the area of the bezel area BZA may be reduced to improve the aesthetic appearance of the electronic device EA.

[0088] Figure 3A and Figure 3B is a cross-sectional view of the electronic device shown in Figure 1A The cross-sectional view of the electronic device in Figure 3A is a cross-sectional view taken along line I-I' in Figure 1A The cross-sectional view of the electronic device in Figure 3B is a cross-sectional view taken along Figure 1AA cross-sectional view taken along line II-II' in []. Here, for ease of description, the housing member 400 (refer to Figure 1A ) is omitted. That is, Figure 3A and Figure 3B are partial cross-sectional views of the display unit DU. Hereinafter, exemplary embodiments of the inventive concept will be described with reference to Figure 3A and Figure 3B .

[0089] As shown in Figure 3A and Figure 3B , the display unit DU includes a window member 100, a display module 200, a first electronic module 310, and a second electronic module 320. In an exemplary embodiment, a first adhesive member AL1 may be disposed between the window member 100 and the display module 200. The first adhesive member AL1 physically bonds the window member 100 to the display module 200. The first adhesive member AL1 may include a transparent adhesive material. For example, the first adhesive member AL1 may include at least one of an optically clear adhesive (OCA), an optically clear resin (OCR), and a pressure-sensitive adhesive (PSA).

[0090] The window member 100 may further include a border layer BZ. The border layer BZ defines a border area BZA. In an exemplary embodiment, the area of the base panel BP on which the border layer BZ is disposed may be defined as the border area BZA, and the area of the base panel BP exposed by the border layer BZ may be defined as the transmissive area TA.

[0091] The display module 200 includes a display panel DP, an optical member OP, a cover plate CP, a second adhesive member AL2, and a third adhesive member AL3. The second adhesive member AL2 is disposed between the display panel DP and the optical member OP and bonds the display panel DP to the optical member OP. The third adhesive member AL3 is disposed between the display panel DP and the cover plate CP and bonds the display panel DP to the cover plate CP.

[0092] Each of the second adhesive member AL2 and the third adhesive member AL3 may include a transparent adhesive material. For example, each of the second adhesive member AL2 and the third adhesive member AL3 may include at least one of an optically clear adhesive (OCA), an optically clear resin (OCR), and a pressure-sensitive adhesive (PSA).

[0093] The display panel DP displays an image IM (refer to Figure 1A ) in response to an electrical signal. In an exemplary embodiment, the display panel DP may be a front-emitting display panel that displays the image IM in the third direction D3.

[0094] The optical member OP is disposed on the front surface of the display panel DP. With respect to the light incident on the display panel DP, the optical member OP can reduce the external light reflectance of the display panel DP. For example, the optical member OP may include at least one of an anti-reflection film, a polarizing film, a color filter, and a gray filter.

[0095] The cover plate CP is disposed on the rear surface of the display panel DP. The cover plate CP can protect the display panel DP from external impacts or reduce the thermal effects on the display panel DP. For example, the cover plate CP may include at least one of a sponge, a plastic panel, a metal panel, and a heat dissipation film.

[0096] The display module 200 includes a first end MHE1 and a second end MHE2. The first end MHE1 is superimposed on the first hole region HA1. The first end MHE1 defines the inner surface of the module hole MH.

[0097] The second end MHE2 defines the side surface of the display module 200. The second end MHE2 may be superimposed on the border region BZA. The border layer BZ is superimposed on the second end MHE2 in a plan view. However, the exemplary embodiments of the inventive concept are not limited thereto. For example, the second end MHE2 may be aligned with the side surface of the window member 100 or superimposed on the transmissive region TA.

[0098] In Figure 3A is shown a portion on which the first hole region HA1 is provided. As Figure 3A shown, the hole plate WP and the first light-shielding pattern BR1 are disposed in the first hole HH1. The first light-shielding pattern BR1 is inserted between the hole plate WP and the base panel BP. Accordingly, the width of the first hole region HA1 in the second direction D2 may correspond to the sum of the width of the first light-shielding pattern BR1 in the second direction D2 and the width of the hole plate WP in the second direction D2. The hole plate WP stably protects the first electronic module 310 from external contamination or external impacts.

[0099] The first hole region HA1 is superimposed on the first electronic module 310. In an embodiment, the first electronic module 310 is inserted into the module hole MH. However, the exemplary embodiments of the inventive concept are not limited thereto. For example, the first electronic module 310 may be disposed outside the module hole MH while being superimposed on the module hole MH.

[0100] As described above, the external signal provided through the first hole region HA1 is provided to the first electronic module 310 through the module hole MH. The first electronic module 310 processes the provided external signal to provide an electrical signal to the display module 200. For example, the first electronic module 310 may be one of a light-emitting module, a light-detecting module, and a photographing module.

[0101] In Figure 3BIn [the figure], a portion on which a second hole region HA2 is provided is shown. As described above, the second hole region HA2 is defined in the border region BZA. As Figure 3B shown in [the figure], a second light-shielding pattern BR2 is provided in the second hole HH2. The second light-shielding pattern BR2 covers the inner surface of the second hole HH2 in the base panel BP.

[0102] The second end MHE2 of the display module 200 may overlap with the border region BZA. The second electronic module 320 is disposed adjacent to the second end MHE2. The second electronic module 320 may receive an external signal provided through the second hole region HA2 or provide a processed signal to the outside. In an exemplary embodiment, the second electronic module 320 may include at least one of a sound input module and a sound output module.

[0103] In the display unit DU according to an exemplary embodiment, the hole plate WP provided in the second hole region HA2 may be omitted. That is, the second light-shielding pattern BR2 may be exposed to the outside. Accordingly, the input efficiency for receiving an external signal provided to the second electronic module 320 or the output efficiency for providing a processed signal to the outside may be improved. However, the exemplary embodiments of the inventive concept are not limited thereto. For example, the hole plate WP may be provided in the second hole region HA2.

[0104] Figure 4A is schematically showing Figure 1B the region XX in an enlarged plan view. Figure 4B and Figure 4C is a cross-sectional view showing a part of a display panel according to an exemplary embodiment of the inventive concept. Figure 4B and Figure 4C may substantially correspond to the cross-sectional view of the region XX'. Hereinafter, exemplary embodiments of the inventive concept will be described with reference to Figure 4A , Figure 4B and Figure 4C . Meanwhile, elements identical to those described in Figures 1A to 3B are denoted by the same reference numerals, and repeated descriptions thereof will be omitted.

[0105] Referring to Figure 4A and Figure 4B , the display panel DP includes a base layer BS, a plurality of signal lines SL1 and SL2, a plurality of pixels PX, an encapsulation layer ECL, and a planarization layer PL. The base layer BS may include an insulating material. For example, the base layer BS may include glass, a resin film, or a stacked film in which organic layers and inorganic layers are alternately stacked.

[0106] Each of the pixels PX generates light to implement an image IM on the active area AA (refer to Figure 1A). Each of the pixels PX may be connected to a plurality of signal lines. In an embodiment, the first signal line SL1 and the second signal line SL2 in the signal lines are exemplarily described. However, the exemplary embodiments of the inventive concept are not limited thereto. For example, each of the pixels PX according to the exemplary embodiments of the inventive concept may be additionally connected to various signal lines. Hereinafter, one pixel PX will be described with reference to one pixel PX.

[0107] The pixel PX is disposed on the substrate layer BS. In an exemplary embodiment, the auxiliary layer BL may be disposed between the pixel PX and the substrate layer BS. The auxiliary layer BL may be directly disposed on the substrate layer BS to cover the front surface of the substrate layer BS.

[0108] The auxiliary layer BL includes an inorganic material. The auxiliary layer BL may include a barrier layer and / or a buffer layer. Accordingly, the auxiliary layer BL prevents oxygen or moisture introduced through the substrate layer BS from penetrating into the pixel PX, or provides a surface energy smaller than the surface energy of the substrate layer BS, thereby stably disposing the pixel PX.

[0109] Here, at least one of the substrate layer BS and the auxiliary layer BL may be provided in plurality and alternately stacked. In addition, at least one of the barrier layer and the buffer layer of the auxiliary layer BL may be provided in plurality or omitted. However, the exemplary embodiments of the inventive concept are not limited thereto. For example, the display panel DP according to the exemplary embodiments of the inventive concept may have various structures.

[0110] The pixel PX may include a thin film transistor TR and a display element OD. The thin film transistor TR includes a semiconductor pattern SP, a control electrode CE, an input electrode IE, and an output electrode OE. The semiconductor pattern SP is disposed on the auxiliary layer BL. The semiconductor pattern SP may include a semiconductor material. The control electrode CE is separated from the semiconductor pattern SP, and the first insulating layer 10 is located between the control electrode CE and the semiconductor pattern SP.

[0111] Each of the input electrode IE and the output electrode OE is separated from the control electrode CE, and the second insulating layer 20 is located between the input electrode IE and the control electrode CE and between the output electrode OE and the control electrode CE. The input electrode IE and the output electrode OE of the thin film transistor TR pass through the first insulating layer 10 and the second insulating layer 20 and are respectively connected to one side and the other side of the semiconductor pattern SP.

[0112] The third insulating layer 30 is disposed on the second insulating layer 20 to cover the input electrode IE and the output electrode OE. Optionally, in an exemplary embodiment of the inventive concept, a semiconductor pattern SP may be disposed on the control electrode CE. Additionally, the semiconductor pattern SP may be disposed on the input electrode IE and the output electrode OE. Additionally, the input electrode IE and the output electrode OE may be disposed on the same layer as the semiconductor pattern SP and directly connected to the semiconductor pattern SP. As described above, the thin film transistor TR according to an exemplary embodiment of the inventive concept may have various structures. However, the exemplary embodiments of the inventive concept are not limited thereto.

[0113] A display element OD is disposed on the third insulating layer 30. The display element OD may include various elements as long as the element can display light. For example, the display element OD may include an organic light emitting element, an electrophoretic element, an electro-wetting element, and a liquid crystal capacitor. In an embodiment, the display element OD is exemplarily described as an organic light emitting element. The display element OD includes a first electrode E1, a light emitting pattern EP, a control layer EL, and a second electrode E2.

[0114] The first electrode E1 may pass through the third insulating layer 30 and be connected to the thin film transistor TR. Although not shown, the display panel DP may further include an additional connection electrode disposed between the first electrode E1 and the thin film transistor TR. Here, the first electrode E1 may be electrically connected to the thin film transistor TR through the connection electrode.

[0115] A fourth insulating layer 40 is disposed on the third insulating layer 30. The fourth insulating layer 40 may include an organic material and / or an inorganic material and have a single-layer or multi-layer structure.

[0116] An opening may be defined in the fourth insulating layer 40. The opening exposes at least a portion of the first electrode E1. The fourth insulating layer 40 may be a pixel defining layer.

[0117] The light emitting pattern EP may be disposed in the opening and on the first electrode E1 exposed by the opening. The light emitting pattern EP may include a light emitting material. For example, the light emitting pattern EP may be made of at least one of materials that emit red light, green light, and blue light respectively, and include a fluorescent material or a phosphorescent material. The light emitting pattern EP may include an organic light emitting material or an inorganic light emitting material. The light emitting pattern EP may emit light in response to a potential difference between the first electrode E1 and the second electrode E2.

[0118] The control layer EL is disposed between the first electrode E1 and the second electrode E2. The control layer EL is disposed adjacent to the light emitting pattern EP. The control layer EL controls the transfer of charges to improve the light emitting efficiency and lifespan of the display element OD. The control layer EL may include at least one of a hole transporting material, a hole injecting material, an electron transporting material, and an electron injecting material.

[0119] In an exemplary embodiment, the control layer EL is disposed between the light-emitting pattern EP and the second electrode E2. However, the exemplary embodiments of the inventive concept are not limited thereto. For example, the control layer EL may be disposed between the light-emitting pattern EP and the first electrode E1, or may include a plurality of layers stacked in a third direction D3, and the light-emitting pattern EP is between the plurality of layers. Optionally, the control layer EL may be omitted from the display element OD according to the exemplary embodiments of the inventive concept.

[0120] The control layer EL may have an overall shape extending from the active region AA to the peripheral region NAA. The control layer EL may be commonly provided to a plurality of pixels PX.

[0121] The second electrode E2 is disposed on the control layer EL. The second electrode E2 may face the first electrode E1. The second electrode E2 may have an overall shape extending from the active region AA to the peripheral region NAA. The second electrode E2 may be commonly provided to a plurality of pixels. The display element OD disposed on each pixel receives a common power supply voltage (hereinafter, referred to as a second power supply voltage) through the second electrode E2.

[0122] The second electrode E2 may include a transmissive conductive material or a semi-transmissive conductive material. Accordingly, light emitted from the light-emitting pattern EP may be easily emitted through the second electrode E2 in the third direction D3. However, the exemplary embodiments of the inventive concept are not limited thereto. For example, based on the design of the display element OD according to the exemplary embodiments of the inventive concept, the first electrode E1 including a transmissive or semi-transmissive material may be driven by a backlight method or a two-sided light-emitting method that emits light toward both the front surface and the back surface.

[0123] The encapsulation layer ECL is disposed on the display element OD to encapsulate the display element OD. The encapsulation layer ECL may be commonly provided to a plurality of pixels. Although not shown, a cover layer covering the second electrode E2 may be further disposed between the second electrode E2 and the encapsulation layer ECL.

[0124] The encapsulation layer ECL may include a first inorganic layer IOL1, an organic layer OL, and a second inorganic layer IOL2 sequentially stacked in the third direction D3. However, the exemplary embodiments of the inventive concept are not limited thereto. For example, the encapsulation layer ECL may further include a plurality of inorganic layers and a plurality of organic layers.

[0125] The first inorganic layer IOL1 may cover the second electrode E2. The first inorganic layer IOL1 may prevent external moisture or oxygen from penetrating into the display element OD. For example, the first inorganic layer IOL1 may include silicon nitride, silicon oxide, or a combination thereof. The first inorganic layer IOL1 may be formed by a deposition process.

[0126] The organic layer OL may be disposed on the first inorganic layer IOL1 to contact the first inorganic layer IOL1. The organic layer OL may provide a planarized surface on the first inorganic layer IOL1. The organic layer OL may cover the curved portion of the top surface of the first inorganic layer IOL1 or particles present on the first inorganic layer IOL1 to prevent the surface state of the top surface of the first inorganic layer IOL1 from affecting the components disposed on the organic layer OL. Additionally, the organic layer OL may relieve stress between layers in contact with each other. The organic layer OL may include an organic material and is formed by a solution process such as spin coating, slot coating, and inkjet process.

[0127] The second inorganic layer IOL2 is disposed on the organic layer OL to cover the organic layer OL. The second inorganic layer IOL2 may be formed relatively stably on the planar surface of the organic layer OL rather than on the first inorganic layer IOL1. The second inorganic layer IOL2 encapsulates moisture and the like discharged from the organic layer OL to prevent the discharged moisture and the like from being introduced to the outside. The second inorganic layer IOL2 may include silicon nitride, silicon oxide, or a combination thereof. The second inorganic layer IOL2 may be formed by a deposition process.

[0128] The planarization layer PL may be disposed on the encapsulation layer ECL. The planarization layer PL covers the front surface of the encapsulation layer ECL (the encapsulation layer ECL provides a non-uniform front surface) to provide a planarized surface to the active area AA. The above optical member OP (refer to Figure 3A ) may be disposed on the planarization layer PL. However, the exemplary embodiments of the inventive concept are not limited thereto. For example, in the display panel DP according to the exemplary embodiment of the inventive concept, the planarization layer PL may be provided in multiple layers or omitted.

[0129] As Figure 4C shown, the display panel DP-1 may include an encapsulation substrate ECG. Here, the encapsulation layer ECL may be omitted. The encapsulation substrate ECG may include an insulating material. For example, the encapsulation substrate ECG may include a glass substrate or a plastic substrate. The above optical member OP may be disposed on the encapsulation substrate ECG. By including the encapsulation substrate ECG, the display panel DP-1 according to the exemplary embodiment of the inventive concept may have improved reliability against external shocks.

[0130] The encapsulation substrate ECG may be separated from the second electrode E2 by a predetermined distance in the third direction D3. Air or an inert gas may be filled in the space GP between the encapsulation substrate ECG and the second electrode E2.

[0131] The encapsulation substrate ECG is bonded to the base layer BS by a sealing member PSL to seal the pixel PX. The encapsulation substrate ECG may be disposed on the base layer BS while the encapsulation substrate ECG and the base layer BS are separated by a predetermined distance by the sealing member PSL.

[0132] The sealing member PSL may define the inner surface of the module hole MH. The sealing member PSL may include an organic material such as a photocurable resin or a photo-setting resin, or an inorganic material such as a frit seal.

[0133] Although not shown, the display panel DP / DP-1 may further include an input sensing unit for detecting an external input. The input sensing unit includes sensors for detecting external touch, heat, light, pressure, etc. The input sensing unit may be disposed on the encapsulation layer ECL, the planarization layer PL, or the encapsulation substrate ECG. However, the exemplary embodiments of the inventive concept are not limited thereto. For example, the input sensing unit may be disposed in the display panel DP / DP-1 or on the rear surface of the base layer BS while being disposed between the base layer BS and the pixel PX.

[0134] As described above, the module hole MH is defined in the active area AA. Therefore, some pixels PX may be arranged along the edge of the module hole MH. In an exemplary embodiment, the module hole MH passes through the base layer BS, the auxiliary layer BL, the first insulating layer 10, the second insulating layer 20, the control layer EL, the first inorganic layer IOL1, the second inorganic layer IOL2, and the planarization layer PL. Thus, the first end MHE1 may include a perforated cross-section of the base layer BS, the auxiliary layer BL, the first insulating layer 10, the second insulating layer 20, the control layer EL, the first inorganic layer IOL1, the second inorganic layer IOL2, and the planarization layer PL.

[0135] Some of the signal lines SL1 and SL2 may be disposed in the hole area MHA. In Figure 4A and Figure 4B exemplarily show the first signal line SL1 and the second signal line SL2 among a plurality of signal lines SL1 and SL2.

[0136] The first signal line SL1 extends in the first direction D1. The first signal line SL1 is connected to the pixels in the same row arranged in the first direction D1 among the pixels PX. For example, the first signal line SL1 may correspond to a gate line. The first signal line SL1 provides a gate signal for turning on the pixels PX to the corresponding pixels.

[0137] Some of the pixels connected to the first signal line SL1 are disposed on the left side with respect to the module hole MH, while other pixels are disposed on the right side with respect to the module hole MH. Therefore, although some pixels are omitted with respect to the module hole MH, the pixels connected to the first signal line SL1 in the same row may be turned on / off substantially by the same gate signal.

[0138] The first signal line SL1 may be disposed on the same layer as the control electrode CE of the thin film transistor TR. Although the first signal line SL1 is disposed between the first insulating layer 10 and the second insulating layer 20, exemplary embodiments of the inventive concept are not limited thereto. For example, the first signal line SL1 may be disposed on a layer different from the control electrode CE.

[0139] The second signal line SL2 extends in the second direction D2. The second signal line SL2 is connected to pixels arranged in the same column in the second direction D2 in the pixel PX. For example, the second signal line SL2 may correspond to a data line. The second signal line SL2 provides a data signal to the corresponding pixel.

[0140] The second signal line SL2 may be disposed on a layer different from the first signal line SL1. For example, the second signal line SL2 may be disposed on the same layer as the input electrode IE or the output electrode OE of the thin film transistor TR. In an embodiment, the second signal line SL2 is disposed between the second insulating layer 20 and the third insulating layer 30.

[0141] Some pixels connected to the second signal line SL2 are disposed on the upper side with respect to the module hole MH, while other pixels are disposed on the lower side with respect to the module hole MH. Accordingly, although some pixels are omitted with respect to the module hole MH, pixels connected to the second signal line SL2 in the same column may receive a data signal through the same line.

[0142] In the display panel DP according to an exemplary embodiment of the inventive concept, the first signal line SL1 may correspond to a data line, and the second signal line SL2 may correspond to a gate line. Additionally, each of the first signal line SL1 and the second signal line SL2 may be one of a power line, an initialization voltage line, and a light emission control line. Additionally, although not shown, each of the pixels PX may also be connected to another signal line (not shown). However, exemplary embodiments of the inventive concept are not limited thereto.

[0143] The display panel DP according to an exemplary embodiment may further include a recessed pattern GV defined in the hole area MHA. The recessed pattern GV may be defined along an edge of the module hole MH. In an exemplary embodiment, the recessed pattern GV is a closed curve surrounding the module hole MH and has a circular shape similar to the shape of the module hole MH. However, exemplary embodiments of the inventive concept are not limited thereto. For example, the recessed pattern GV may have a shape different from the module hole MH, including a polygon, an ellipse, or a closed curve shape having at least a part of a curve, or a shape including a plurality of patterns that are partially disconnected.

[0144] The recessed pattern GV, which is a pattern recessed from the front surface of the display panel DP, can be formed by removing some components of the display panel DP. However, unlike the module hole MH, the recessed pattern GV does not penetrate the display panel DP. Accordingly, the back surface of the base layer BS that overlaps with the recessed pattern GV is not opened by the recessed pattern GV.

[0145] The recessed pattern GV can be formed by passing through components that are disposed below the encapsulation layer ECL and adjacent to the module hole MH, except for only a part of the base layer BS. In an exemplary embodiment, the recessed pattern GV can be formed by connecting a through-hole portion defined in the auxiliary layer BL and a recessed portion defined in the base layer BS. The inner surface of the recessed pattern GV can be formed such that the through-hole portion defined in the auxiliary layer BL and the recessed portion defined in the base layer BS are covered by the first inorganic layer IOL1 and the second inorganic layer IOL2. In an exemplary embodiment, the second inorganic layer IOL2 can provide the inner surface of the recessed pattern GV.

[0146] In addition, the recessed pattern GV can have an undercut shape including a tip TP (see Figure 4B ) that protrudes toward the inside of the recessed pattern GV. In an embodiment, the tip TP can be formed such that a part of the auxiliary layer BL protrudes more toward the inside of the recessed pattern GV than the base layer BS. The display panel DP according to an exemplary embodiment of the inventive concept can have various layer structures as long as the tip can be formed on the recessed pattern GV. However, the exemplary embodiment of the inventive concept is not limited thereto.

[0147] The display panel DP may further include a predetermined organic pattern EL-P disposed in the recessed pattern GV. The organic pattern EL-P may include the same material as the control layer EL. Alternatively, the organic pattern EL-P may include the same material as the second electrode E2 or a cover layer (not shown). The organic pattern EL-P may have a single-layer or multi-layer structure.

[0148] The organic pattern EL-P may be disposed in the recessed pattern GV while being separated from the control layer EL and the second electrode E2. As Figure 4B shown, the organic pattern EL-P may not be exposed to the outside by being covered by the first inorganic layer IOL1.

[0149] According to an exemplary embodiment of the inventive concept, the concave pattern GV blocks the continuity of the control layer EL connected to the active area AA from the side surface of the module hole MH. The control layer EL may be disconnected in the area overlapping the concave pattern GV. The control layer EL may be a moving path for external contaminants such as moisture or air. The layer exposed by the module hole MH may be blocked by the concave pattern GV, for example, the path through which moisture or air introduced from the control layer EL, passing through the hole area MHA and introduced into the pixel PX may be blocked by the concave pattern GV. Therefore, the reliability of the display panel DP in which the module hole MH is defined may be improved.

[0150] In the display panel DP according to the exemplary embodiment of the inventive concept, the recessed pattern GV may be provided in plurality, and the plurality of recessed patterns GV may be spaced apart from each other in the hole area MHA. Alternatively, the recessed pattern GV may be filled with a portion of the organic layer OL. Alternatively, in the display panel DP according to the exemplary embodiment of the inventive concept, the recessed pattern GV may be omitted. However, the exemplary embodiment of the inventive concept is not limited thereto.

[0151] According to an exemplary embodiment of the inventive concept, the module hole MH passes through the display panel DP. An inner surface of the module hole MH may be defined by perforated profiles of a plurality of components of the display panel DP.

[0152] Figure 5A , Figure 5B and Figure 5C is a cross-sectional view showing a portion of a display device according to an exemplary embodiment of the inventive concept. Figures 5A to 5C In order to facilitate the description, Figure 3A Only the optical member OP and the window members 100-A, 100-B and 100-C are shown in the region of FIG. In addition, for the convenience of description, the light path corresponding to the user's viewing angle is shown as an arrow. Figures 5A to 5C Describes exemplary embodiments of the inventive concept. Figures 1A to 4C The same elements as those described in are denoted by the same reference numerals, and repeated descriptions will be omitted.

[0153] like Figure 5A As shown in , the window member 100-A includes a base panel BP-A, a light shielding pattern BR-A and an aperture plate WP-A. The optical member OP defining the module hole MH includes an end OP_E defining the inner surface of the module hole MH. When light L1 corresponding to the user's viewing angle (hereinafter, referred to as the first light) is incident into the window member 100-A at an angle of the first angle AG1, the first light L1 passes through the highest point P1 (hereinafter, referred to as the first point) of the light shielding pattern BR-A that contacts the aperture plate WP-A and passes through the window member 100-A.

[0154] Here, the first light L1 may not intersect the end OP_E of the optical member OP. That is, the end OP_E of the optical member OP may not be visible to the user. Although a part of the light incident at a position farther from the module hole MH than the first point P1 while maintaining the first angle AG1 may have a path toward the end OP_E of the optical member OP, before the light has this path, the light is dissipated by being absorbed by the light-shielding pattern BR-A.

[0155] According to an exemplary embodiment of the inventive concept, although the module hole MH is defined in the optical member OP, due to the further inclusion of the light-shielding pattern BR-A, the end OP_E of the optical member OP may not be visible to the user. In addition, by controlling the size of the hole control region HA_A such that the light-shielding pattern BR-A is disposed at a position where the first light L1 may not reach the end OP_E of the optical member OP, a defect in which the end OP_E of the optical member OP is seen from the outside can be prevented, and the appearance of the display device can be improved.

[0156] As Figure 5B shown, the window member 100-B includes a base panel BP-B, a light-shielding pattern BR-B, and a hole plate WP-B. Except for the position of the light-shielding pattern BR-B, the window member 100-B includes components corresponding to the components of the window member 100-A in Figure 5A . Repeated descriptions will be omitted hereinafter.

[0157] As Figure 5B shown, when the light L2 corresponding to the user's viewing angle (hereinafter, referred to as the second light) is incident on the window member 100-B at an angle of the second angle AG2, the second light L2 passes through the lowest point P2 (hereinafter, referred to as the second point) in contact with the base panel BP-B of the light-shielding pattern BR-B and passes through the window member 100-B.

[0158] Here, the second light L2 may not intersect the end OP_E of the optical member OP. That is, the end OP_E of the optical member OP may not be visible to the user. Although a part of the light incident at a position closer to the module hole MH than the second point P2 while maintaining the second angle AG2 may have a path toward the end OP_E of the optical member OP, before the light has this path, the light is dissipated by being absorbed by the light-shielding pattern BR-B.

[0159] According to an exemplary embodiment of the inventive concept, although the module hole MH is defined in the optical member OP, the end OP_E of the optical member OP may not be visible to a user because the light-blocking pattern BR-B is further included. In addition, by controlling the size of the hole region HA_B such that the light-blocking pattern BR-B is disposed at a position where the second light L2 may not reach the end OP_E of the optical member OP, a defect in which the end OP_E of the optical member OP is seen from the outside can be prevented, and the appearance of the display device can be improved.

[0160] As Figure 5C shown, the window member 100-C includes a base panel BP-C, a light-blocking pattern BR-C, and a hole plate WP-C. Except for the position of the light-blocking pattern BR-C, the window member 100-C includes components corresponding to the components of the window member 100-A in Figure 5A and the window member 100-B in Figure 5B . Hereinafter, repeated descriptions will be omitted.

[0161] When light L3 corresponding to a user's viewing angle (hereinafter, referred to as third light) is incident on the window member 100-C at an angle of a third angle AG3, the third light L3 passes through the lowest point P3 (hereinafter, referred to as the third point) in contact with the base panel BP-C of the light-blocking pattern BR-C and passes through the window member 100-C. In the exemplary embodiment, although the first angle AG1, the second angle AG2, and the third angle AG3 are equal to each other, the angles may include all angles that a user's viewing angle can reach.

[0162] Here, the third light L3 may be incident on the end OP_E of the optical member OP. However, the third point P3 corresponds to a point that also contacts the light-blocking pattern BR-C. Therefore, although the third light L3 may have a path toward the end OP_E of the optical member OP, at the same time, the third light L3 is absorbed and dissipated by the light-blocking pattern BR-C.

[0163] According to an exemplary embodiment of the inventive concept, the hole region HA_C may have substantially the same size and shape as the size and shape of the module hole MH. According to an exemplary embodiment of the inventive concept, although the module hole MH is defined in the optical member OP, the end OP_E of the optical member OP may not be visible to a user because the light-blocking pattern BR-C is further included. Therefore, by controlling the size of the hole region HA_C, a defect in which the end OP_E of the optical member OP is seen from the outside can be prevented, and the appearance of the display device can be improved.

[0164] Figure 6A , Figure 6B and Figure 6C are cross-sectional views showing a part of a display device according to an exemplary embodiment of the inventive concept. InFigures 6A to 6C In order to facilitate the description, the region corresponding to the region YY' in Figure 3A is enlarged. Hereinafter, exemplary embodiments of the inventive concept will be described with reference to Figures 6A to 6C . Meanwhile, elements identical to those described in Figures 1A to 5C are denoted by the same reference numerals, and repeated descriptions will be omitted.

[0165] As shown in Figure 6A , a light-shielding pattern BR is disposed between the aperture plate WP and the base panel BP. The light-shielding pattern BR contacts each of the base panel BP and the aperture plate WP to bond the base panel BP to the aperture plate WP and fill the space between the aperture plate WP and the base panel BP. The distance WD between the aperture plate WP and the base panel BP may correspond to the width of the light-shielding pattern BR in the second direction D2.

[0166] The first end MHE of the display module includes an end OP_E of the optical member OP and an end AL1_E of the first adhesive member AL1. The light-shielding pattern BR is disposed at a position farther from the module aperture than the first end MHE.

[0167] The light-shielding pattern BR may have a front surface BR_U that is aligned with the front surface WP_U of the aperture plate WP and the front surface BP_U of the base panel BP. Accordingly, the front surface BR_U of the light-shielding pattern BR, the front surface WP_U of the aperture plate WP, and the front surface BP_U of the base panel BP may define a plane.

[0168] As shown in Figure 6B , the distance WD1 between the aperture plate WP-1 and the base panel BP-1 may be increased to be greater than Figure 6A the distance WD. For example, the aperture plate WP-1 may have a shape having the same surface area as the module aperture. The side surface of the aperture plate WP-1 and the first end MHE of the display module may be aligned with each other in the third direction D3. The front surface WP_U1 of the aperture plate WP-1, the front surface BR_U1 of the light-shielding pattern BR-1, and the front surface BP_U1 of the base panel BP-1 may define a plane.

[0169] The distance WD1 between the aperture plate WP-1 and the base panel BP-1 may substantially correspond to the width of the light-shielding pattern BR-1. According to an embodiment, although the distance WD1 between the aperture plate WP-1 and the base panel BP-1 is increased, the aperture plate WP-1 and the base panel BP-1 may be stably bonded to each other by the light-shielding pattern BR-1.

[0170] Referring to Figure 6C , the distance WD2 between the aperture plate WP-2 and the base panel BP-2 may be less than Figure 6AThe distance WD therein. As the distance WD2 between the orifice plate WP-2 and the base panel BP-2 decreases, the width of the light-shielding pattern BR-2 can be reduced. Here, the front surface WP_U2 of the orifice plate WP-2, the front surface BR_U2 of the light-shielding pattern BR-2, and the front surface BP_U2 of the base panel BP-2 are not aligned. According to an exemplary embodiment of the inventive concept, even though the distance WD2 between the orifice plate WP-2 and the base panel BP-2 decreases, the orifice plate WP-2 and the base panel BP-2 can be stably coupled to each other even through a small light-shielding pattern BR-2.

[0171] Figure 7A , Figure 7B , Figure 7C and Figure 7D are cross-sectional views showing a part of a display device according to an exemplary embodiment of the inventive concept. In Figures 7A to 7D , for ease of description, a region corresponding to the region YY' in Figure 3A is shown. Hereinafter, an exemplary embodiment of the inventive concept will be described with reference to Figures 7A to 7D . Meanwhile, elements identical to those described in Figures 1A to 6C are denoted by the same reference numerals, and repeated descriptions will be omitted.

[0172] As shown in Figure 7A , the orifice plate WP-3 and the base panel BP-3 may have an integral shape. The orifice plate WP-3 and the base panel BP-3 may be connected to each other. The front surface WP_U3 of the orifice plate WP-3 and the front surface BP_U3 of the base panel BP-3 are connected to each other to have an integral shape.

[0173] The recessed portion BP_H defined in the base panel BP-3 may be a groove. The recessed portion BP_H (hereinafter, referred to as the groove) may be defined by being recessed from the rear surface of the base panel BP-3. The groove BP_H may not extend to the front surface of the base panel BP-3. Since the groove BP_H is defined in the base panel BP-3, the orifice plate WP-3 and the base panel BP-3 may be connected to each other to have an integral shape.

[0174] The light-shielding pattern BR-3 is disposed in the groove BP_H. Accordingly, the light-shielding pattern BR-3 may not be exposed from the front surface BP_U3 of the base panel BP-3 or the front surface WP_U3 of the orifice plate WP-3. According to an exemplary embodiment of the inventive concept, even though the light-shielding pattern BR-3 is further included, the front surface of the window member may be provided by one front surface BP_U3 of the base panel BP-3.

[0175] As Figure 7BAs shown, at least a part of the light-shielding pattern BR-4 may partially cover the front surface BP_U of the base panel BP or the front surface WP_U of the orifice plate WP. Specifically, the light-shielding pattern BR-4 may include a first part P10 and a second part P20. The first part P10 fills the distance WD21 between the orifice plate WP and the base panel BP. The first part P10 may have substantially the same thickness as the base panel BP.

[0176] The second part P20 is connected to the first part P10. The second part P20 may cover a part of the front surface BP_U of the base panel BP and a part of the front surface WP_U of the orifice plate WP. The second part P20 may have a width WD22 equal to or greater than the distance WD21 between the orifice plate WP and the base panel BP.

[0177] The second part P20 may be formed such that a part of the light-shielding pattern BR-4 provided in a fluid state in the process of forming the light-shielding pattern BR-4 is discharged to the front surface of the base panel BP. According to an exemplary embodiment of the inventive concept, the light-shielding pattern BR-4 may have various shapes according to process environments or conditions. However, the exemplary embodiments of the inventive concept are not limited thereto.

[0178] As Figure 7C shown, the recessed part BP_H1 defined in the base panel BP may include a first recessed part H11 and a second recessed part H21. The first recessed part H11 is recessed from the rear surface of the base panel BP and has a first width in the second direction D2. The second recessed part H21 is connected to the first recessed part H11. The second recessed part H21 is recessed from the first recessed part H11 and has a second width in the second direction D2. Each of the first recessed part H11 and the second recessed part H21 may be a groove. The second width may be smaller than the first width.

[0179] The light-shielding pattern BR-5 fills the recessed part BP-H1. Specifically, the light-shielding pattern BR-5 may include a first part P11 that fills the first recessed part H11 and a second part P21 that is connected to the first part P11 and fills the second recessed part H21. Since the front surface BR_U of the light-shielding pattern BR-5 does not extend through the base panel BP, the second part P21 is not exposed from the front surface BP_U of the base panel BP. According to an exemplary embodiment of the inventive concept, the light-shielding pattern BR-5 may have an inverted "T" shape in a cross-sectional view.

[0180] The light-shielding pattern BR-5 can be superimposed on the first end MHE of the display module. Here, since the light-shielding pattern BR-5 is inserted into the base panel BP, the light-shielding pattern BR-5 (specifically, the second part P21) does not protrude from the rear surface of the base panel BP. Therefore, the problem of forming a stepped portion on the optical member OP or the adhesive member AL1 provided on the rear surface of the base panel BP can be prevented by the light-shielding pattern BR-5. Therefore, problems such as delamination of the first end MHE can be solved to improve the reliability of the electronic device.

[0181] In addition, as Figure 7D shown, the recessed portion BP_H2 defined in the window member may include a groove and a through hole. Specifically, the recessed portion BP_H2 includes a first recessed portion H12 and a second recessed portion H22. The first recessed portion H12 may be a groove recessed from the rear surface of the base panel BP. The first recessed portion H12 may correspond to Figure 7C the first recessed portion H11 in

[0182] The second recessed portion H22 may be a through hole connected to the first recessed portion H12 and recessed from the first recessed portion H12 in the third direction D3. The second recessed portion H22 extends until the front surface BP_U of the base panel BP.

[0183] The recessed portion BP_H2 may be defined by each of the base panel BP and the hole plate WP. Specifically, the first recessed portion H12 may be defined by a groove defined in the base panel BP and a groove defined in the hole plate WP. In addition, the second recessed portion H22 may be defined by the spaced-apart space between the base panel BP and the hole plate WP.

[0184] The light-shielding pattern BR-6 is disposed in the recessed portion BP_H2 to fill the recessed portion BP_H2. Specifically, the light-shielding pattern BR-6 includes a first part P12 that fills the first recessed portion H12 and a second part P22 that fills the second recessed portion H22. The first part P12 defines the same plane as the rear surface of the base panel BP. Therefore, the problem of forming a stepped portion of the optical member OP or the adhesive member AL1 can be prevented by the light-shielding pattern BR-6 to solve the problem of delamination of the first end MHE.

[0185] In addition, the second part P22 includes a front surface BR_U that defines the same plane as the front surface BP_U of the base panel BP and the front surface WP_U of the hole plate WP. Therefore, the sense of difference that may be generated on the front surface of the window member due to the light-shielding pattern BR-6 can be reduced.

[0186] According to an exemplary embodiment of the inventive concept, since the light-shielding pattern BR-5 includes a first part P11 and a second part P21 and the light-shielding pattern BR-6 includes a first part P12 and a second part P22, the area superposed with the first end MHE can be relatively large. Accordingly, it is possible to easily prevent a problem in which a user views the first end MHE from the front surface of the window member, thereby improving the appearance of the electronic device.

[0187] Figure 8A is an exploded perspective view showing a window member according to an exemplary embodiment of the inventive concept. Figure 8B is a cross-sectional view showing a part of an electronic device. Hereinafter, exemplary embodiments of the inventive concept will be described with reference to Figure 8A and Figure 8B Description of exemplary embodiments of the inventive concept.

[0188] As Figure 8A shown, the window member 100-N may further include a predetermined notch NT. The notch NT may be defined at one side of the base panel BP. In an embodiment, the notch NT may be defined such that a part of one side extending in the first direction D1 is recessed in the opposite direction of the second direction D2.

[0189] The window member 100-N includes a first light-shielding pattern BR1 and a second light-shielding pattern BR2-N. The first light-shielding pattern BR1 may be disposed in the first hole HH1 to couple the hole plate WP to the base panel BP. The first light-shielding pattern BR1 corresponds to Figure 2 the first light-shielding pattern BR1 in

[0190] so that a repeated description thereof will be omitted. The second light-shielding pattern BR2-N may be disposed along the inner surface of the notch NT. The second light-shielding pattern BR2-N may have a shape in which a part of a closed curve is opened in a plan view. One side defining the shape of the second light-shielding pattern BR2-N may have a shape in which a part of the closed curve is removed on a plane. For example, the second light-shielding pattern BR2-N may have various shapes, such as a polygon shape with one side opened, a circular shape with one side opened, or an elliptical shape with one side opened. The second light-shielding pattern BR2-N may have a shape corresponding to the shape of the notch NT on a plane.

[0191] The notch NT may be defined in an area superposed with the electronic module 320, where the electronic module 320 may correspond to Figure 1B the second electronic module 320 in

[0192] The electronic module 320 may be disposed adjacent to the second end MHE2 of the display module 200. According to an exemplary embodiment, since the bezel layer BZ and the second light-shielding pattern BR2-N are further included, the second end MHE2 is not visible to the user. Accordingly, the appearance of the electronic device may be improved.

[0193] According to an exemplary embodiment of the inventive concept, the window member 100-N may include recessed portions having various shapes as long as the recessed portions are superimposed on the electronic module 320. In the window member 100-N, the recessed portions are provided as the first holes HH1 and the notches NT. In addition, according to an exemplary embodiment of the inventive concept, since the light-shielding patterns BR1 and BR2-N are provided corresponding to the recessed portions having various shapes, the problem in which the end portion MHE2 of the display module is seen through the recessed portions may be easily solved.

[0194] Figure 9 is an exploded perspective view of an electronic device EA according to an exemplary embodiment of the inventive concept. Hereinafter, exemplary embodiments of the inventive concept will be described with reference to Figure 9 Here, elements identical to those described in Figures 1A to 8B are denoted by the same reference numerals, and repeated descriptions thereof will be omitted.

[0195] As Figure 9 shown in, the window member 100-A includes a base panel BP-A and a light-shielding pattern BR-A. A predetermined recessed portion HH-A may be defined in the base panel BP-A. The recessed portion HH-A may be defined as a through hole having a strip shape extending in a first direction D1 on a plane.

[0196] The light-shielding pattern BR-A may be disposed in the recessed portion HH-A. The light-shielding pattern BR-A may cover an inner surface of the recessed portion HH-A. The light-shielding pattern BR-A may have an elongated ring shape corresponding to the shape of the recessed portion HH-A.

[0197] In the window member 100-A according to an exemplary embodiment of the inventive concept, the bezel layer BZ (refer to Figure 3A ) may be omitted. Accordingly, a front surface of the window member 100-A may be set as a transmissive area TA_A.

[0198] The display module 200-A may have a front surface IS including an active area AA and a peripheral area NAA. The front surface IS is set to face the window member 100-A. The display module 200-A may include a display panel DP (refer to Figure 3A ) for displaying an image on the active area AA and an optical member OP (refer to Figure 3A ) disposed on the display panel DP.

[0199] In addition, the module hole MH-A passing through the display module 200-A may be defined in the active area AA of the display module 200-A. The module hole MH-A may have a strip shape extending in a first direction D1 on a plane.

[0200] The module hole MH-A may be stacked with all of the first electronic module 310 and the second electronic module 320. Each of the first electronic module 310 and the second electronic module 320 may be inserted into the module hole MH-A to be stacked with the recessed portion HH-A on a plane. According to an exemplary embodiment of the inventive concept, the first electronic module 310 and the second electronic module 320 may receive an external signal or provide an output signal to the outside through the shared module hole MH-A and the shared recessed portion HH-A.

[0201] According to an exemplary embodiment of the inventive concept, the light-shielding pattern BR-A may prevent a user from seeing an end portion of an inner surface of the display module 200-A defining the module hole MH-A through the window member 100-A. The light-shielding pattern BR-A may block a viewing path of the user facing the inner surface of the module hole MH-A to prevent the inner surface of the module hole MH-A from being seen. Accordingly, the appearance of the electronic device EA may be improved.

[0202] According to an exemplary embodiment of the inventive concept, although the inner surface of the recessed portion HH-A is covered with the light-shielding pattern BR-A, components such as a separate hole plate WP (refer to Figure 2 ) are not provided in the recessed portion HH-A. However, the exemplary embodiment of the inventive concept is not limited thereto. For example, a hole plate inserted into the recessed portion HH-A may be further provided.

[0203] According to an exemplary embodiment of the inventive concept, a problem in which a user sees an end portion of a display module including an optical member through a window member may be easily solved. In addition, a problem of delamination of an end portion of the display module disposed adjacent to an electronic module may be prevented to improve the reliability of the electronic device.

[0204] Although certain exemplary embodiments and implementations have been described herein, other embodiments and modifications will be apparent from this description. Accordingly, the inventive concept is not limited to these embodiments, but is limited to the claims and the broader scope of various apparent modifications and equivalent arrangements that will be apparent to those of ordinary skill in the art.
