Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority from and the benefit of Korean Patent Application No. 10-2020-0020250, filed on Feb. 19, 2020, which is hereby incorporated by reference for all purposes as if fully set forth herein. 
     BACKGROUND 
     Field 
     Exemplary implementations of the invention relate generally to an electronic device, and more specifically, to a foldable electronic device. 
     Discussion of the Background 
     An electronic device includes an active region that is activated by an electrical signal. The active region is used to sense an input applied from the outside and to display various images to provide information to a user. As, recently, various shapes of electronic devices are developed, it is necessary to diversify the shape of the active region. 
     The above information disclosed in this Background section is only for understanding of the background of the inventive concepts, and, therefore, it may contain information that does not constitute prior art. 
     SUMMARY 
     Electronic devices constructed according to the principles and exemplary implementations of the invention have an active region with an increased area. For example, one or more of electronic modules of the electronic device may overlap and/or be surrounded by the active region rather than a peripheral region to decrease the size of the peripheral region. Accordingly, the active region may have a relatively large area. 
     Electronic devices constructed according to the principles and exemplary implementations of the invention have improved reliability. For example, the electronic device may include first and second patterns to block light wherein the first pattern covers the peripheral region, and the second pattern surrounds an electronic module of the electronic device that is received in the active region. The electronic module may sense various types of signals such as visible light passing through the layers to generate images and/or electrical signals. The first pattern may be thicker than the second pattern to permit layers covering and/or disposed on the second pattern and the electronic module to be planarized, thereby reducing curvature and/or uneven portions in the covering layers. Therefore, it may be possible to reduce or prevent deterioration in the quality of the images and/or the electrical signals generated by the electronic module. In addition, the second pattern of the electronic device may be formed and/or printed on a layer having an uneven and/or a rough surface. Accordingly, the probability that the second pattern becomes detached from the layer may be reduced, thereby improving the reliability of the electronic device. 
     Additional features of the inventive concepts will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the inventive concepts. 
     According to one aspect of the invention, an electronic device includes: a display panel having an active region and a peripheral region adjacent to the active region; an electronic module disposed below the display panel; a first light-blocking element disposed on the display panel and overlapping the peripheral region; and a second light-blocking element disposed on the electronic module with the display panel interposed therebetween. A hole may be at least partially surrounded by the active region is defined in a portion of the display panel.

     DETAILED DESCRIPTION 
     In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of various exemplary embodiments or implementations of the invention. As used herein “embodiments” and “implementations” are interchangeable words that are non-limiting examples of devices or methods employing one or more of the inventive concepts disclosed herein. It is apparent, however, that 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 to avoid unnecessarily obscuring various exemplary embodiments. Further, various exemplary embodiments may be different, but do not have to be exclusive. For example, specific shapes, configurations, and characteristics of an exemplary embodiment may be used or implemented in another exemplary embodiment without departing from the inventive concepts. 
     Unless otherwise specified, the illustrated exemplary embodiments are to be understood as providing exemplary features of varying detail of some ways in which the inventive concepts may be implemented in practice. Therefore, unless otherwise specified, the features, components, modules, layers, films, panels, regions, and/or aspects, etc. (hereinafter individually or collectively referred to as “elements”), of the various embodiments may be otherwise combined, separated, interchanged, and/or rearranged without departing from the inventive concepts. 
     The use of cross-hatching and/or shading in the accompanying drawings is generally provided to clarify boundaries between adjacent elements. As such, neither the presence nor the absence of cross-hatching or shading conveys or indicates any preference or requirement for particular materials, material properties, dimensions, proportions, commonalities between illustrated elements, and/or any other characteristic, attribute, property, etc., of the elements, unless specified. Further, in the accompanying drawings, the size and relative sizes of elements may be exaggerated for clarity and/or descriptive purposes. When an exemplary embodiment may be implemented differently, a specific process order may be performed differently from the described order. For example, two consecutively described processes may be performed substantially at the same time or performed in an order opposite to the described order. Also, like reference numerals denote like elements. 
     When an element, such as a layer, is referred to as being “on,” “connected to,” or “coupled to” another element or layer, it may be directly on, connected to, or coupled to the other element or layer or intervening elements or layers may be present. When, however, 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 present. To this end, the term “connected” may refer to physical, electrical, and/or fluid connection, with or without intervening elements. Further, the D 1 -axis, the D 2 -axis, and the D 3 -axis are not limited to three axes of a rectangular coordinate system, such as the x, y, and z—axes, and may be interpreted in a broader sense. For example, the D 1 -axis, the D 2 -axis, and the D 3 -axis may be perpendicular to one another, or may represent different directions that are not perpendicular to one another. 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” may be construed as X only, Y only, Z only, or any combination of two or more of X, Y, and Z, such as, for instance, XYZ, XYY, YZ, and ZZ. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. 
     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 element. Thus, a first element discussed below could be termed a second element without departing from the teachings of the disclosure. 
     Spatially relative terms, such as “beneath,” “below,” “under,” “lower,” “above,” “upper,” “over,” “higher,” “side” (e.g., as in “sidewall”), and the like, may be used herein for descriptive purposes, and, thereby, to describe one elements relationship to another element(s) as illustrated in the drawings. Spatially relative terms are intended to encompass different orientations of an apparatus in use, operation, and/or manufacture in addition to the orientation depicted in the drawings. For example, if the apparatus in the drawings is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. Furthermore, the apparatus may be otherwise oriented (e.g., rotated  90  degrees or at other orientations), and, as such, the spatially relative descriptors used herein should be interpreted accordingly. 
     The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, the singular forms, “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Moreover, the terms “comprises,” “comprising,” “includes,” and/or “including,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, components, and/or groups thereof, but do 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 as terms of degree, and, as such, are utilized to account for inherent deviations in measured, calculated, and/or provided values that would be recognized by one of ordinary skill in the art. 
     Various exemplary embodiments are described herein with reference to sectional and/or exploded illustrations that are schematic illustrations of idealized exemplary embodiments and/or intermediate structures. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, exemplary embodiments disclosed herein should not necessarily be construed as limited to the particular illustrated shapes of regions, but are to include deviations in shapes that result from, for instance, manufacturing. In this manner, regions illustrated in the drawings may be schematic in nature and the shapes of these regions may not reflect actual shapes of regions of a device and, as such, are not necessarily intended to be limiting. 
     Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure is a part. Terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized or overly formal sense, unless expressly so defined herein. 
       FIG.  1 A  is a perspective view of an exemplary embodiment of an electronic device constructed according to the principles of the invention.  FIG.  1 B  is a perspective view of the electronic device of  FIG.  1 A  as it is being folded along a folding axis.  FIG.  1 A  illustrates an unfolded position of an electronic device  1000 , and  FIG.  1 B  illustrates a folded position of the electronic device  1000 . 
     Referring to  FIGS.  1 A and  1 B , the electronic device  1000  may be selectively activated by an electrical signal applied thereto. For example, the electronic device  1000  may be a computer device such as a cellular phone, a tablet, a car navigation system, a gaming machine, or a wearable device, but exemplary embodiments are not limited to these examples.  FIG.  1 A  illustrates an example in which the electronic device  1000  is the cellular phone. 
     The electronic device  1000  may include an active region  1000 A, which is used to display an image. When the electronic device  1000  is the unfolded position, the active region  1000 A may include a plane defined by a first direction DR 1  and a second direction DR 2 . The thickness direction of the electronic device  1000  may be parallel to a third direction DR 3  intersecting the first direction DR 1  and the second direction DR 2 . Accordingly, a front or top surface and a rear or bottom surface of each member constituting the electronic device  1000  may be defined based on the third direction DR 3 . 
     The active region  1000 A may include a first region  1000 A 1 , a second region  1000 A 2 , and a third region  1000 A 3 . The second region  1000 A 2  may be bent or folded along a folding axis FX extending in the second direction DR 2 . Accordingly, the first region  1000 A 1  and the third region  1000 A 3  may be referred to as non-foldable regions, and the second region  1000 A 2  may be referred to as a foldable region. 
     When the electronic device  1000  is folded, the first region  1000 A 1  and the third region  1000 A 3  may face each other. Accordingly, in a fully-folded position, the active region  1000 A may not be exposed to the outside, and this position may be referred to as an in-folding position. However, exemplary embodiments are not limited to this folding operation of the electronic device  1000 . 
     As an example, when the electronic device  1000  is folded, the first region  1000 A 1  and the third region  1000 A 3  may be opposite to each other. For example, in the folded position, the active region  1000 A may be exposed to the outside, and this position may be referred to as an out-folding position. 
     In an exemplary embodiment, only one of the in-folding and out-folding operations may be allowed for the electronic device  1000 . In another exemplary embodiment, both of the in-folding and out-folding operations may be allowed for the electronic device  1000 . In this case, a specific region (e.g., the second region  1000 A 2 ) of the electronic device  1000  may be folded in an in-folding and out-folding manner. In other exemplary embodiment, a region of the electronic device  1000  may be folded in the in-folding manner, and another region of the electronic device  1000  may be folded in the out-folding manner. 
       FIGS.  1 A and  1 B  illustrate an example, in which one foldable region and two non-foldable regions are provided, but the numbers of the foldable and non-foldable regions are not limited to this example. For instance, the electronic device  1000  may include two or more non-foldable regions and at least one foldable region, which is disposed between adjacent ones of the non-foldable regions. 
       FIGS.  1 A and  1 B  illustrate an example, in which the folding axis FX is generally parallel to a short axis of the electronic device  1000 , but exemplary embodiments are not limited to this example. For example, the folding axis FX may be generally parallel to a long axis of the electronic device  1000  (e.g., the first direction DR 1 ). In this case, the first region  1000 A 1 , the second region  1000 A 2 , and the third region  1000 A 3  may be sequentially arranged in the second direction DR 2 . 
     A plurality of sensing regions  100 SA 1 ,  100 SA 2 , and  100 SA 3  may be defined in the electronic device  1000 . In the sensing regions  100 SA 1 ,  100 SA 2 , and  100 SA 3 , the electronic device  1000  may include electronic modules to provide to and/or receive from the outside various types of signals, such as visible light and infrared light.  FIG.  1 A  illustrates an example, in which three sensing regions  100 SA 1 ,  100 SA 2 , and  100 SA 3  are provided, but the number of the sensing regions is not limited to this example. 
     The sensing regions  100 SA 1 ,  100 SA 2 , and  100 SA 3  may include a first sensing region  100 SA 1 , a second sensing region  100 SA 2 , and a third sensing region  100 SA 3 . For example, the first sensing region  100 SA 1  may overlap a camera module, the second sensing region  100 SA 2  and the third sensing region  100 SA 3  may overlap an ambient light sensor, but exemplary embodiments are not limited to this example. 
     Each of the electronic modules may receive an external input, which is provided through the first sensing region  100 SA 1 , the second sensing region  100 SA 2 , or the third sensing region  100 SA 3 , or may provide an output to the outside through the first sensing region  100 SA 1 , the second sensing region  100 SA 2 , or the third sensing region  100 SA 3 . 
     The first sensing region  100 SA 1  may be enclosed and/or completely surrounded by the active region  1000 A, and the second sensing region  100 SA 2  and the third sensing region  100 SA 3  may be included in the active region  1000 A. For example, the second sensing region  100 SA 2  and the third sensing region  100 SA 3  may display an image. Each of the first sensing region  100 SA 1 , the second sensing region  100 SA 2 , and the third sensing region  100 SA 3  may have a light transmittance (hereinafter “transmittance”) that is higher than that of the active region  1000 A. In addition, the transmittance of the first sensing region  100 SA 1  may be higher than the transmittance of each of the second sensing region  100 SA 2  and the third sensing region  100 SA 3 . 
     According to an exemplary embodiment, at least one of the electronic modules may overlap the active region  1000 A, and others of the electronic modules may be enclosed and/or completely surrounded by the active region  1000 A. Thus, it is unnecessary to confine a region, on which the electronic modules will be disposed, within a peripheral region  1000 NA around the active region  1000 A. As a result, the ratio of an area of the active region  1000 A to a total area of the electronic device  1000  may be increased. 
       FIG.  2    is a cross-sectional view taken along line I-I′ of  FIG.  1 A  to illustrate an exemplary embodiment of the electronic device.  FIG.  3 A  is a cross-sectional view of an exemplary embodiment of the display panel of  FIG.  2   . 
     Referring to  FIG.  2   , the electronic device  1000  may include a display panel  100 , upper functional layers, and lower functional layers. 
     Referring to  FIG.  3 A , the display panel  100  may be an element configured to generate an image and to sense an input applied from the outside. For example, the display panel  100  may include a display layer  110  and a sensor layer  120 . The thickness of the display panel  100  may range from 25 μm to 35 μm (in particular, about 30 μm), but the thickness of the display panel  100  is not limited thereto. 
     The display layer  110  may be an element configured to substantially generate an image. The display layer  110  may be a light-emitting type display layer (e.g., an organic light emitting display layer, a quantum dot display layer, or a micro-LED display layer). 
     The display layer  110  may include a base layer  111 , a circuit layer  112 , a light-emitting device layer  113 , and an encapsulation layer  114 . 
     The base layer  111  may include a synthetic resin film. The synthetic resin layer may include a thermosetting resin. The base layer  111  may have a multi-layered structure. For example, the base layer  111  may have a triple-layered structure including a synthetic resin layer, an adhesive layer, and a synthetic resin layer. The synthetic resin layer may be a polyimide-based resin layer, but exemplary embodiments are not limited to a specific material. The synthetic resin layer may include at least one of acryl resins, methacryl resins, polyisoprene resins, vinyl resins, epoxy resins, urethane resins, cellulose resins, siloxane resins, polyamide resins, or perylene resins. In addition, the base layer  111  may include a glass substrate or a substrate made of an organic/inorganic composite material. 
     The circuit layer  112  may be disposed on the base layer  111 . The circuit layer  112  may include an insulating layer, a semiconductor pattern, a conductive pattern, and a signal line. An insulating layer, a semiconductor layer, and a conductive layer may be formed on the base layer  111  using a coating or depositing process, and then may be selectively patterned through a plurality of photolithography processes. Thereafter, a semiconductor pattern, a conductive pattern, and a signal line included in the circuit layer  112  may be formed. 
     The light-emitting device layer  113  may be disposed on the circuit layer  112 . The light-emitting device layer  113  may include a light-emitting device. For example, the light-emitting device layer  113  may include an organic light emitting material, a quantum dot, a quantum rod, or a micro LED. 
     The encapsulation layer  114  may be disposed on the light-emitting device layer  113 . The encapsulation layer  114  may include an inorganic layer, an organic layer, and an inorganic layer, which are sequentially stacked, but the layers constituting the encapsulation layer  114  are not limited to this example. 
     The inorganic layers may protect the light-emitting device layer  113  from moisture and oxygen, and the organic layer may protect the light-emitting device layer  113  from a contamination material, such as dust particles. The inorganic layers may include a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer. The organic layer may include an acrylic organic layer, but exemplary embodiments are not limited thereto. 
     The sensor layer  120  may be disposed on the display layer  110 . The sensor layer  120  may sense an external input provided from the outside. For example, the external input may be a user input produced by a user. For example, the user input may include various types of external inputs, such as a part of a user&#39;s body, light, heat, pressure, or a pen. 
     The sensor layer  120  may be formed on the display layer  110  through a successive process. In this case, the sensor layer  120  is directly disposed on the display layer  110 . This means that a another element is not disposed between the sensor layer  120  and the display layer  110 . For example, an additional adhesive member may not be disposed between the sensor layer  120  and the display layer  110 . 
     In exemplary embodiments, the sensor layer  120  may be coupled to the display layer  110  through an adhesive member. The adhesive member may be a typical adhesive or sticking agent. 
     Referring back to  FIG.  2   , the upper functional layers may be disposed on the display panel  100 . For example, the upper functional layers may include an anti-reflection member  200  and an upper member  300 . 
     The anti-reflection member  200  may be referred to as an anti-reflection layer. The anti-reflection member  200  may reduce reflectance of an external light that is incident from the outside. The anti-reflection member  200  may include an elongated-type synthetic resin film. For example, the anti-reflection member  200  may be provided by dyeing an iodine compound on a polyvinylalcohol (PVA) film. However, the material for the anti-reflection member  200  is not limited to this example. The thickness of the anti-reflection member  200  may range from 25 μm to 35 μm (in particular, about 31 μm), but the thickness of the anti-reflection member  200  is not limited thereto. 
     The anti-reflection member  200  may be coupled to the display panel  100  through a first adhesive layer  1010 . The first adhesive layer  1010  may be a transparent adhesive layer, such as a pressure sensitive adhesive (PSA) film, an optically clear adhesive (OCA) film, or an optically clear resin (OCR). An adhesive layer or agent, which will be described below, may be formed of or include a typical adhesive or sticking agent. The thickness of the first adhesive layer  1010  may range from 20 μm to 30 μm (in particular, 25 μm), but the thickness of the first adhesive layer  1010  is not limited thereto. 
     In an exemplary embodiment, the first adhesive layer  1010  may be omitted, and in this case, the anti-reflection member  200  may be directly disposed on the display panel  100 . In this case, an additional adhesive layer may not be disposed between the anti-reflection member  200  and the display panel  100 . 
     The upper member  300  may be disposed on the anti-reflection member  200 . The upper member  300  may include a first hard coating layer  310 , a protection layer  320 , a first upper adhesive layer  330 , a window  340 , a second upper adhesive layer  350 , a light-blocking layer  360 , an impact absorbing layer  370 , and a second hard coating layer  380 . Elements included in the upper member  300  are not limited to the afore-described elements. In an exemplary embodiment, at least one of the afore-described elements may be omitted, or in another exemplary embodiment, other elements may be added. 
     The first hard coating layer  310  may be the outermost layer of the electronic device  1000 . The first hard coating layer  310  may be a functional layer coated on the protection layer  320 , which is used to improve usage properties of the electronic device  1000 . For example, due to the first hard coating layer  310 , it may be possible to improve anti-fingerprint, contamination-preventing, scratch-preventing properties of the electronic device  1000 . 
     The protection layer  320  may be disposed below the first hard coating layer  310 . The protection layer  320  may protect elements disposed below the protection layer  320 . The first hard coating layer  310 , an anti-fingerprint layer, and so forth may be additionally provided on the protection layer  320  to improve chemical-resistant and wear resistant properties. The protection layer  320  may include a film whose elastic modulus at the room temperature is less than 15 GPa. The thickness of the protection layer  320  may range from 50 μm to 60 μm (in particular, 55 μm), but the thickness of the protection layer  320  is not limited thereto. In an exemplary embodiment, the protection layer  320  may be omitted. 
     The first upper adhesive layer  330  may be disposed below the protection layer  320 . The protection layer  320  and the window  340  may be coupled to each other by the first upper adhesive layer  330 . The thickness of the first upper adhesive layer  330  may range from 20 μm to 30 μm (in particular, about 25 μm), but the thickness of the first upper adhesive layer  330  is not limited thereto. 
     The window  340  may be disposed below the first upper adhesive layer  330 . The window  340  may be formed of or include an optically-transparent insulating material. For example, the window  340  may include a glass substrate or a synthetic resin film. In the case where the window  340  is the glass substrate, the thickness of the window  340  may be smaller than or equal to 80 μm or may be, for example, about 30 μm, but the thickness of the window  340  is not limited thereto. 
     In the case where the window  340  is the synthetic resin film, the window  340  may include a polyimide (PI) film or a polyethylene terephthalate (PET) film. 
     The window  340  may have a multi- or single-layered structure. For example, the window  340  may include a plurality of synthetic resin films, which are coupled to each other by an adhesive agent, or may include a glass substrate and a synthetic resin film, which are coupled to each other by an adhesive agent. 
     The second upper adhesive layer  350  may be disposed below the window  340 . The window  340  and the impact absorbing layer  370  may be coupled to each other by the second upper adhesive layer  350 . The thickness of the second upper adhesive layer  350  may range from 30 μm to 40 μm (in particular, about 35 μm), but the thickness of the second upper adhesive layer  350  is not limited thereto. 
     In an exemplary embodiment, a sidewall  340 S of the window  340  and a sidewall  350 S of the second upper adhesive layer  350  may be disposed inside sidewalls of other layers (e.g., a sidewall  1000 S of the display panel  100  and a sidewall  320 S of the protection layer  320 ), when viewed in a plan view. This means that the sidewalls  340 S and  350 S are closer to the active region  1000 A than other comparative elements. 
     The positional relationship between layers may be changed by the folding operation of the electronic device  1000 . According to an exemplary embodiment, since the sidewall  340 S of the window  340  is disposed inside the sidewall  1000 S of the display panel  100  and the sidewall  320 S of the protection layer  320 , it may be possible to prevent or suppress the sidewall  340 S of the window  340  from protruding out of the sidewall  320 S of the protection layer  320 , even when the positional relationship between layers is changed due to the folding operation. Accordingly, it may be possible to reduce the possibility that the sidewall  340 S of the window  340  is used as a pathway of an external impact. As a result, it may be possible to reduce the probability that a crack occurs in the window  340 . 
     A first distance  340 W between the sidewall  340 S of the window  340  and the sidewall  320 S of the protection layer  320  may be greater than a specific distance. Here, the first distance  340 W may be a distance that is measured in the first direction DR 1 . In addition, the first distance  340 W may correspond to a distance between the sidewall  340 S and the sidewall  320 S, when viewed in a plan view. 
     The first distance  340 W may range from 180 μm to 205 μm (in particular, 196 μm), but exemplary embodiments are not limited to this example. In an exemplary embodiment, the first distance  340 W may be greater than or equal to 50 μm and may be, for example, about 300 μm. As the first distance  340 W increases, the protrusion length of the protection layer  320  relative to the window  340  may increase, and a portion of the protection layer  320  may be bent and may be attached to other elements (e.g., a case). In addition, in the case where an area of the protection layer  320  increases, it may be possible to reduce the probability that contamination material, which is supplied from a region on the protection layer  320 , enters the region below the protection layer  320 . 
     Furthermore, the window  340  and the second upper adhesive layer  350  may be adhered to the impact absorbing layer  370  through a lamination process. The areas of the window  340  and the second upper adhesive layer  350  may be smaller than an area of the impact absorbing layer  370 , in consideration of the process tolerance in the lamination process. In addition, the area of the second upper adhesive layer  350  may be smaller than the area of the window  340 . In an exemplary embodiment, during the process of attaching the window  340 , pressure may be exerted on the second upper adhesive layer  350 . The second upper adhesive layer  350  may be elongated in the first and second directions DR 1  and DR 2  by the pressure. Here, to prevent the second upper adhesive layer  350  from protruding out of the window  340 , the area of the second upper adhesive layer  350  may be smaller than the area of the window  340 . 
     In the case where the first upper adhesive layer  330  and the second upper adhesive layer  350  are attached to each other, the window  340  may be hardly slipped during the folding operation of the electronic device  1000 , and in this case, a buckling phenomenon may occur in the window  340 . However, according to an exemplary embodiment, the area of the second upper adhesive layer  350  may be smaller than the area of the window  340 . Accordingly, the first upper adhesive layer  330  may not be attached to the second upper adhesive layer  350 , and it may be possible to prevent or suppress contamination material from being attached to the second upper adhesive layer  350 . 
     A second distance  350 W between the sidewall  350 S of the second upper adhesive layer  350  and the sidewall  320 S of the protection layer  320  may be greater than a specific distance. Here, the second distance  350 W may be a distance that is measured in the first direction DR 1 . In addition, the second distance  350 W may correspond to the distance between the sidewall  350 S and the sidewall  320 S, when viewed in a plan view. 
     In an exemplary embodiment, the second distance  350 W may be about 392 μm, but exemplary embodiments are not limited thereto. For example, the second distance  350 W may be within a range from 292 μm to 492 μm. 
     The impact absorbing layer  370  may be a functional layer used to protect the display panel  100  from an external impact. The impact absorbing layer  370  may be selected from one of films whose elastic modulus at the room temperature is greater than or equal to  1  GPa. The impact absorbing layer  370  may be an elongated film having an optical function. For example, the impact absorbing layer  370  may be an optic axis control film. The impact absorbing layer  370  may be, for example, a biaxially-oriented PET film. The thickness of the impact absorbing layer  370  may range from 35 μm to 45 μm (in particular, about 41 μm), but the thickness of the impact absorbing layer  370  is not limited thereto. In an exemplary embodiment, the impact absorbing layer  370  may be omitted. 
     The second hard coating layer  380  may be formed on a surface of the impact absorbing layer  370 . The second hard coating layer  380  may include an organic coating agent, an inorganic coating agent, or a coating agent made of an organic/inorganic composite material, and if any material is used to reduce a haze issue, it may be used for the second hard coating layer  380 . The term ‘haze’ may be defined as the extent of diffusion of light that is incident into a test material, and if the haze is high, the light may be scattered to cause an opaque haze issue. 
     Each of the top and bottom surfaces of the impact absorbing layer  370  may include an uneven portion and/or surface. The top surface of the impact absorbing layer  370  may be in contact with the second upper adhesive layer  350 . Accordingly, the uneven portion of the top surface of the impact absorbing layer  370  may be filled with the second upper adhesive layer  350 . Thus, it may be possible to prevent an optical issue (e.g., an increase in haze) from occurring on the top surface of the impact absorbing layer  370 . The bottom surface of the impact absorbing layer  370  may be planarized by the second hard coating layer  380 . In the case where a first hole  101 H (e.g., see  FIG.  4 A ) is provided to cut a second adhesive layer  1020 , the bottom surface exposed by the first hole  101 H (e.g., see  FIG.  4 A ) may have a substantially smooth surface. Since the second hard coating layer  380  covers an uneven and/or rough surface of the impact absorbing layer  370 , it may be possible to suppress a haze issue which may occur in the uneven and/or rough surface. 
     The light-blocking layer  360  may be disposed between the impact absorbing layer  370  and the second upper adhesive layer  350 . The light-blocking layer  360  may be provided on the top surface of the impact absorbing layer  370  by a printing method. The light-blocking layer  360  may overlap the peripheral region  1000 NA. The light-blocking layer  360  may be a colored layer formed by a coating method. The light-blocking layer  360  may include a polymer resin and a pigment contained in the polymer resin. In an exemplary embodiment, the polymer resin may be an acrylic resin or polyester, and the pigment may be a carbon-based pigment. However, the material for the light-blocking layer  360  is not limited to this example. 
     The light-blocking layer  360  may be formed by a printing method, after forming the second hard coating layer  380  on the impact absorbing layer  370 . Since the impact absorbing layer  370  has an uneven and/or rough surface, compared with the second hard coating layer  380 , the adhesive strength may be stronger when the light-blocking layer  360  is printed on the impact absorbing layer  370  than when the light-blocking layer  360  is printed on the second hard coating layer  380 . Since the light-blocking layer  360  is directly printed on the uneven and/or rough surface of the impact absorbing layer  370 , the probability that the light-blocking layer  360  is detached from the impact absorbing layer  370  may be reduced. That is, since the probability that the light-blocking layer  360  becomes detached from a print-target surface (e.g., the impact absorbing layer  370 ) is reduced, the product reliability of the electronic device  1000  may be improved. 
     The upper member  300  may be coupled to the anti-reflection member  200  by the second adhesive layer  1020 . The second adhesive layer  1020  may be formed of or include a typical adhesive or sticking agent. The thickness of the second adhesive layer  1020  may range from 20 μm to 30 μm (in particular, about 25 μm), but the thickness of the second adhesive layer  1020  is not limited thereto. 
     The lower functional layers may be disposed on the display panel  100 . For example, the lower functional layers may include a lower protection film  400 , a cushion member  500 , a first lower member  600 , a second lower member  700 , and a height-difference compensation member  800 . Elements included in the lower functional layers are not limited to the afore-described elements. In an exemplary embodiment, at least one of the afore-described elements may be omitted, or in another exemplary embodiment, other element may be added. 
     The lower protection film  400  may be coupled to the rear surface of the display panel  100  by a third adhesive layer  1030 . The lower protection film  400  may prevent a scratch from being formed on the rear surface of the display panel  100 , during the fabrication process of the display panel  100 . The lower protection film  400  may be a colored polyimide film. For example, the lower protection film  400  may be an opaque yellow film, but exemplary embodiments are not limited to this example. 
     The thickness of the lower protection film  400  may range from 30 μm to 50 μm (in particular, about 40 μm). The thickness of the third adhesive layer  1030  may range from 13 μm to 25 μm (in particular, about 18 μm). However, the thickness of the lower protection film  400  and the thickness of the third adhesive layer  1030  are not limited thereto. 
     The cushion member  500  may be disposed below the lower protection film  400 . The cushion member  500  may protect the display panel  100  from an impact provided through the underlying element. The impact-resistant property of the electronic device  1000  may be improved by the cushion member  500 . 
     The cushion member  500  may include a first cushion adhesive layer  510 , a barrier film  520 , a cushion layer  530 , and a second cushion adhesive layer  540 . Elements included in the cushion member  500  are not limited to the afore-described elements. In an exemplary embodiment, at least one of the afore-described elements may be omitted, or in another exemplary embodiment, other element may be added. 
     The first cushion adhesive layer  510  and the second cushion adhesive layer  540  may be formed of or include a typical adhesive or sticking agent. The first cushion adhesive layer  510  may be attached to the lower protection film  400 , and the second cushion adhesive layer  540  may be attached to the first lower member  600 . The thickness of the first cushion adhesive layer  510  may range from 20 μm to 30 μm (in particular, about 25 μm). The thickness of the second cushion adhesive layer  540  may range from 4 μm to 15 μm (in particular, about 8 μm). However, the thicknesses of the first cushion adhesive layer  510  and the second cushion adhesive layer  540  are not limited thereto. 
     The barrier film  520  may improve an impact-resistant property. The barrier film  520  may prevent the display panel  100  from being deformed. The barrier film  520  may be a synthetic resin film (e.g., a polyimide film), but exemplary embodiments are not limited to this example. The thickness of the barrier film  520  may range from 30 μm to 40 μm (in particular, about 35 μm), but the thickness of the barrier film  520  is not limited thereto. 
     The cushion layer  530  may include, for example, a foam or a sponge. The foam may include a polyurethane foam or a thermoplastic polyurethane foam. In the case where the cushion layer  530  includes the foam, the cushion layer  530  may be formed by using the barrier film  520  as a base layer. For example, the cushion layer  530  may be formed by foaming a foaming agent on the barrier film  520 . 
     The thickness of the cushion layer  530  may range from 80 μm to 120 μm (in particular, about 100 μm), but the thickness of the cushion layer  530  is not limited thereto. 
     At least one of the barrier film  520  and the cushion layer  530  may have a color absorbing light. For example, at least one of the barrier film  520  and the cushion layer  530  may be black. In this case, it may be possible to prevent elements, which are disposed below the cushion member  500 , from being recognized by a user. 
     The first lower member  600  may be disposed below the cushion member  500 . The first lower member  600  may include a plate  610 , a lower adhesive layer  620 , and a cover layer  630 . Elements included in the first lower member  600  are not limited to the afore-described elements. In an exemplary embodiment, at least one of the afore-described elements may be omitted, or in another exemplary embodiment, other element may be added. 
     The plate  610  may be formed of or include a material whose elastic modulus at the room temperature is greater than or equal to 60 GPa. For example, the plate  610  may be SUS 304 , but exemplary embodiments are not limited to this example. The plate  610  may support element disposed thereon. In addition, the heat-dissipation performance of the electronic device  1000  may be improved by the plate  610 . 
     An opening  611  may be defined in a portion of the plate  610 . The opening  611  may be defined in a region overlapped with the second region  1000 A 2 . When viewed in a plan view or in the third direction DR 3 , the opening  611  may overlap the second region  1000 A 2 . A shape of a portion of the plate  610  may be more easily deformed by the opening  611 . 
     The cover layer  630  may be attached to the plate  610  by the lower adhesive layer  620 . The lower adhesive layer  620  may be formed of or include a typical adhesive or sticking agent. The cover layer  630  may cover the opening  611  of the plate  610 . Accordingly, it may be possible to further prevent a contamination material from entering the opening  611 . 
     The cover layer  630  may be formed of or include a material, whose elastic modulus is lower than that of the plate  610 . For example, the cover layer  630  may be formed of or include thermoplastic polyurethane, but exemplary embodiments are not limited to this example. 
     The thickness of the plate  610  may range from 120 μm to 180 μm (in particular, about 150 μm). The thickness of the lower adhesive layer  620  may range from 4 μm to 15 μm (in particular, about 8 μm). The thickness of the cover layer  630  may range from 4 μm to 15 μm (in particular, about 8 μm). However, the thickness of the plate  610 , the thickness of the lower adhesive layer  620 , and the thickness of the cover layer  630  are not limited to the afore-described values. 
     The second lower members  700  may be disposed below the first lower member  600 . The second lower members  700  may be spaced apart from each other. For example, one of the second lower members  700  may be disposed in the first region  1000 A 1 , and another of the second lower members  700  may be disposed in the third region  1000 A 3 . 
     Each of the second lower members  700  may be attached to the first lower member  600  by fourth adhesive layers  1040 . For example, one of the fourth adhesive layers  1040  may be attached to a bottom surface of the first lower member  600 , which is overlapped with the first region  1000 A 1 , and another of the fourth adhesive layers  1040  may be attached to the bottom surface of the first lower member  600 , which is overlapped with the third region  1000 A 3 . In other words, the fourth adhesive layers  1040  may not overlap the second region  1000 A 2 . The thickness of each of the fourth adhesive layers  1040  may range from 8 μm to 15 μm (in particular, about 8 μm), but the thickness of each of the fourth adhesive layers  1040  is not limited thereto. 
     In an exemplary embodiment, a height-difference compensation film may be further disposed between each of the second lower members  700  and the first lower member  600 . For example, the height-difference compensation film may be provided in a region overlapped with the second region  1000 A 2 . A surface (hereinafter, a first surface) of the height-difference compensation film may have an adhesive strength that is lower than another surface. For example, the first surface may not have adhesive strength. The first surface may be a surface that faces the first lower member  600 . 
     Each of the second lower members  700  may include a lower plate  710 , a heat-dissipation sheet  720 , and an insulating film  730 . Elements included in each of the second lower members  700  are not limited to the afore-described elements. In an exemplary embodiment, at least one of the afore-described elements may be omitted, or in another exemplary embodiment, other element may be added. 
     In an exemplary embodiment, a plurality of the lower plates  710  may be provided. One of the lower plates  710  may overlap the first region  1000 A 1  and a portion of the second region  1000 A 2 , and another of the lower plates  710  may overlap another portion of the second region  1000 A 2  and the third region  1000 A 3 . 
     The lower plates  710  may be spaced apart from each other, in the second region  1000 A 2 . The lower plates  710  may be disposed as close as possible to each other and may support a region, in which the opening  611  of the plate  610  is formed. For example, the lower plates  710  may prevent a shape of a region, in which the opening  611  of the plate  610  is defined from being changed by pressure exerted by an element thereon. 
     In addition, the lower plates  710  may prevent elements disposed on the second lower members  700  from being deformed by elements disposed below the second lower members  700 . 
     Each of the lower plates  710  may include a metal alloy (e.g., copper alloy). However, the material for the lower plates  710  is not limited to this example. The thickness of each of the lower plates  710  may range from 60 μm to 100 μm (in particular, about 80 μm), but exemplary embodiments are not limited to this thickness of the lower plates  710 . 
     The heat-dissipation sheet  720  may be attached to a bottom surface of the lower plate  710 . The heat-dissipation sheet  720  may be a thermal conduction sheet having high thermal conductivity. For example, the heat-dissipation sheet  720  may include a heat-dissipation layer  721 , a first heat-dissipation adhesive layer  722 , a second heat-dissipation adhesive layer  723 , and a gap tape  724 . 
     The gap tape  724  may be attached to the first heat-dissipation adhesive layer  722  and the second heat-dissipation adhesive layer  723 , which are spaced apart from each other with the heat-dissipation layer  721  interposed therebetween. The gap tape  724  may be composed of a plurality of layers. For example, the gap tape  724  may include a substrate layer, an upper adhesive layer disposed on a top surface of the substrate layer, and a lower adhesive layer disposed on a bottom surface of the substrate layer. 
     The heat-dissipation layer  721  may be attached to the lower plate  710  by the first heat-dissipation adhesive layer  722 . The heat-dissipation layer  721  may be hermetically sealed by the first heat-dissipation adhesive layer  722 , the second heat-dissipation adhesive layer  723 , and the gap tape  724 . The heat-dissipation layer  721  may be a graphited polymer film. The polymer film may be, for example, a polyimide film. The thickness of each of the first heat-dissipation adhesive layer  722  and the second heat-dissipation adhesive layer  723  may range from 3 μm to 8 μm (in particular, about 5 μm). The thickness of each of the heat-dissipation layer  721  and the gap tape  724  may range from 10 μm to 25 μm (in particular, about 17 μm). However, the thickness of each of the first heat-dissipation adhesive layer  722 , the second heat-dissipation adhesive layer  723 , the heat-dissipation layer  721 , and the gap tape  724  may be not limited to the afore-described ranges or values. 
     The insulating film  730  may be attached to a bottom surface of the heat-dissipation sheet  720 . For example, the insulating film  730  may be attached to the second heat-dissipation adhesive layer  723 . The insulating film  730  may prevent rattling noises from occurring in the electronic device  1000 . The thickness of the insulating film  730  may be about 15 μm, but exemplary embodiments are not limited to this example. 
     The height-difference compensation member  800  may be attached to a bottom surface of the plate  610 . For example, the lower adhesive layer  620  may be attached to a bottom surface of a portion of the plate  610 , and the height-difference compensation member  800  may be attached to a bottom surface of another portion of the plate  610 . 
     The height-difference compensation member  800  may include a first compensation adhesive layer  810 , a height-difference compensation film  820 , and a second compensation adhesive layer  830 . The first compensation adhesive layer  810  may be attached to a bottom surface of the plate  610 . The height-difference compensation film  820  may be a synthetic resin film. The second compensation adhesive layer  830  may be attached to the bottom surface of the height-difference compensation film  820  and a set. The thickness of each of the first compensation adhesive layer  810  and the second compensation adhesive layer  830  may range from 13 μm to 25 μm (in particular, about 17 μm). The thickness of each of the first compensation adhesive layer  810  and the second compensation adhesive layer  830  is not limited to this example, and the thickness of the height-difference compensation film  820  may be determined depending on the thicknesses of the first and second compensation adhesive layers  810  and  830 . 
       FIG.  3 B  is a cross-sectional view of another exemplary embodiment of the display panel of  FIG.  2   . 
     Referring to  FIG.  3 B , a display panel  100   aa  may further include an anti-reflection layer  130 , when compared with the display panel  100  described with reference to  FIG.  3 A . In this case, the anti-reflection member  200  (e.g., see  FIG.  2   ) and the first adhesive layer  1010  (e.g., see  FIG.  2   ) may be omitted from the electronic device  1000  (e.g., see  FIG.  2   ) including the display panel  100   aa.    
     The display panel  100   aa  may include the display layer  110 , the sensor layer  120 , and the anti-reflection layer  130 . 
     In an exemplary embodiment, the anti-reflection layer  130  may include color filters. The color filters may be arranged in a specific arrangement. The arrangement of the color filters may be determined in consideration of colors of lights to be emitted from pixels in the display layer  110 . In addition, the anti-reflection layer  130  may further include a black matrix, which is disposed adjacent to the color filters. 
     In an exemplary embodiment, the anti-reflection layer  130  may include a destructive interference structure. For example, the destructive interference structure may include a first reflection layer and a second reflection layer which are provided on different layers. The first reflection layer and the second reflection layer may allow a first reflection light and a second reflection light, which are respectively reflected by them, to destructively interfere with each other, and this may make it possible to reduce reflectance of the external light. 
       FIG.  4 A  is an exploded perspective view illustrating an exemplary embodiment of some elements of the electronic device of  FIG.  1 A . 
       FIG.  4 A  exemplarily illustrates the light-blocking layer  360 , the display panel  100 , and electronic modules  2000  of the electronic device  1000  of  FIG.  2   . The electronic modules  2000  may include a camera module  2100  and an ambient light sensor  2200 . 
     The ambient light sensor  2200  may include a light-emitting module  2210  and a light-receiving module  2220 . The light-emitting module  2210  and the light-receiving module  2220  may be mounted on a single substrate. The light-emitting module  2210  may be configured to generate and output light. For example, the light-emitting module  2210  may emit infrared light, and the light-emitting module  2210  may include a light-emitting diode. The light-receiving module  2220  may sense infrared light. The light-receiving module  2220  may be activated when the level of the infrared light is higher than a specific level. The light-receiving module  2220  may include a CMOS sensor. The infrared light emitted from the light-emitting module  2210  may be reflected by an external object (e.g., a user&#39;s finger or face) and may be incident into the light-receiving module  2220 . 
     An active region  100 A and a peripheral region  100 NA may be defined in the display panel  100 . The active region  100 A may correspond to the active region  1000 A shown in  FIG.  1 A , and the peripheral region  100 NA may correspond to the peripheral region  1000 NA shown in  FIG.  1 A . 
     The first sensing region  100 SA 1  overlapped with the camera module  2100  may be at least partially enclosed and/or completely surrounded by the active region  100 A, and the second sensing region  100 SA 2  and the third sensing region  100 SA 3 , which are respectively overlapped with the light-emitting module  2210  and the light-receiving module  2220 , may be portions of the active region  100 A. 
     The first hole  101 H may be defined in a portion of the display panel  100 . The first hole  101 H may be at least partially surrounded by the active region  100 A. The first hole  101 H may correspond to the first sensing region  100 SA 1 . As such, the camera module  2100  may receive an external light input, which is provided through the first hole  101 H. 
     The electronic device  1000  may include light-blocking elements disposed on the display panel  100  to block light. The light-blocking elements to block light may be associated with the peripheral region  100 NA and the first hole  101 H. In an exemplary embodiment, the light-blocking layer  360  may include a first light-blocking element in the form of a first light-blocking pattern  361  and a second light-blocking element in the form of a second light-blocking pattern  362 . The first light-blocking pattern  361  may be a pattern covering and/or overlapping the peripheral region  100 NA. The second light-blocking pattern  362  may be disposed near and/or adjacent to the first hole  101 H. At least portion of the second light-blocking pattern  362  may overlap the first hole  101 H. When viewed in a plan view, the second light-blocking pattern  362  may enclose and/or completely surround the camera module  2100 . In addition, the second light-blocking pattern  362  may be enclosed and/or completely surrounded by the active region  100 A. 
     The first light-blocking pattern  361  and the second light-blocking pattern  362  may be disposed on the same layer. For example, the first light-blocking pattern  361  and the second light-blocking pattern  362  may be formed concurrently by the same process. The first light-blocking pattern  361  may be referred to as a peripheral light-blocking pattern, and the second light-blocking pattern  362  may be referred to as a light-blocking pattern. 
       FIG.  4 B  is a cross-sectional view taken along line IV-IV′ of  FIG.  4 A  to illustrate an exemplary embodiment of the electronic device. 
     Referring to  FIGS.  4 A and  4 B , the first light-blocking pattern  361  and the second light-blocking pattern  362  may have different thicknesses from each other. For example, a first thickness TK 1  of the first light-blocking pattern  361  may be greater than a second thickness TK 2  of the second light-blocking pattern  362 . The first thickness TK 1  may be greater than the second thickness TK 2  and may be smaller than or equal to 10 times the second thickness TK 2 , and in an exemplary embodiment, the first thickness TK 1  may be great than or equal to 3 times the second thickness TK 2 and may be smaller than or equal to 10 times the second thickness TK 2 . However, the range of the second thickness TK 2  is not limited thereto. For example, the second thickness TK 2  may range from 0.5 μm to 1.5 μm, the first thickness TK 1  may range from 1.5 μm to 5 μm, but exemplary embodiments are not limited to this example. For example, the first light-blocking pattern  361  may be about 4 μm, and the second light-blocking pattern  362  may be about 1 μm. 
     In the case where the second thickness TK 2  is smaller than 0.5 μm, the second light-blocking pattern  362  may not block an external light sufficiently. In addition, in the case where the second thickness TK 2  is greater than 1.5 μm, an uneven portion may be formed in layers covering the second light-blocking pattern  362  by the second light-blocking pattern  362 . In the case where an uneven portion is formed in the layers, the sharpness of an image obtained by the camera module  2100  may be deteriorated. 
     According to an exemplary embodiment, the first light-blocking pattern  361  and the second light-blocking pattern  362  may be designed to have different thicknesses from each other. The first thickness TK 1  may be designed to be thicker than the second thickness TK 2 . Accordingly, the peripheral region  100 NA may be covered with the first light-blocking pattern  361  such that light may be blocked sufficiently. In addition, the second thickness TK 2  may be designed to be thinner than the first thickness TK 1 . As the second thickness TK 2  of the second light-blocking pattern  362  becomes thinner, curvature and/or an uneven portion generated in the layers covering the second light-blocking pattern  362  may be reduced and therefore the layers may be planarized. Accordingly, it may be possible to prevent or reduce an uneven portion from being formed in a region, which is overlapped with the camera module  2100 . As a result, it may be possible to prevent deterioration of the quality of images obtained by the camera module  2100 . 
     The width  361 TW of the first light-blocking pattern  361  may be greater than the width  362 TW of the second light-blocking pattern  362 . For example, the width  361 TW of the first light-blocking pattern  361  may be equal to or greater than 0.67 mm, and the width  362 TW of the second light-blocking pattern  362  may be about 0.52 mm. However, the width  361 TW of the first light-blocking pattern  361  and the width  362 TW of the second light-blocking pattern  362  are not limited to these values. 
     The first light-blocking pattern  361  may be disposed in the peripheral region  1000 NA (e.g., see  FIG.  2   ) of the electronic device  1000  (e.g., see  FIG.  2   ), and the second light-blocking pattern  362  may be disposed in the active region  1000 A (e.g., see  FIG.  1 A ) of the electronic device  1000  (e.g., see  FIG.  2   ). Thus, the first light-blocking pattern  361  may be covered with another element (e.g., a case) during the process of assembling the electronic device  1000  or may be partially cut by an additional cutting process. Accordingly, the first light-blocking pattern  361  may be designed to have a width greater than the second light-blocking pattern  362 . 
       FIG.  4 C  is a cross-sectional view taken along line IV-IV′ of  FIG.  4 A  to illustrate another exemplary embodiment of the electronic device. 
     Referring to  FIGS.  4 A and  4 C , the first light-blocking pattern  361  may include one or more stacked layers in the form of printing layers  361 L 1 ,  361 L 2 , and  361 L 3  stacked on the impact absorbing layer  370 , and the second light-blocking pattern  362  may include one or more stacked layers in the form of a printing layer  362 L disposed on the impact absorbing layer  370 . The number of the printing layers  361 L 1 ,  361 L 2 , and  361 L 3  in the first light-blocking pattern  361  may be different from the number of a printing layer  362 L in the second light-blocking pattern  362 . In  FIG.  4 C , one printing layer may mean a layer that is formed by a single printing process. 
     The first light-blocking pattern  361  may be provided by a triple color printing, and the second light-blocking pattern  362  may be provided by a single color printing. That is, the repetition number of the printing process to form the first light-blocking pattern  361  may be greater than that of the printing process to form the second light-blocking pattern  362 . 
     The number of layers included in each of the first and second light-blocking patterns  361  and  362  may not be limited to the example of  FIG.  4 C , as long as the number of printing layers constituting the first light-blocking pattern  361  is greater the number of printing layers constituting the second light-blocking pattern  362 . 
       FIG.  5    is a rear view of an exemplary embodiment of some elements of the electronic device of  FIG.  1 A . 
     The display panel  100 , the height-difference compensation member  800 , the heat-dissipation layer  721 , and the gap tape  724  are exemplarily illustrated in  FIG.  5   . 
     Referring to  FIGS.  4 A and  5   , a first hole  101 H, a second hole  102 H, and a third hole  103 H may correspond to the first sensing region  100 SA 1 , the second sensing region  100 SA 2 , and the third sensing region  100 SA 3 , respectively. 
     The first hole  101 H, the second hole  102 H, and the third hole  103 H may be formed by removing some elements of the electronic device  1000  (e.g., see  FIG.  1 A ), and this will be described in more detail below. 
     The first hole  101 H may overlap the height-difference compensation member  800 , and each of the second hole  102 H and the third hole  103 H may overlap the gap tape  724 . Accordingly, when viewed in a plan view, the first hole  101 H may be enclosed and/or completely surrounded by the height-difference compensation member  800 , and each of the second hole  102 H and the third hole  103 H may be enclosed and/or completely surrounded by the gap tape  724 . 
       FIG.  6    is a cross-sectional view taken along line II-II′ of  FIG.  1 A  to illustrate an exemplary embodiment of the electronic device. 
       FIG.  6    illustrates the first hole  101 H, in which the camera module  2100  is inserted. The first hole  101 H may include a first hole portion  101 H 1 , a second hole portion  101 H 2 , and a third hole portion  101 H 3 . 
     The first hole portion  101 H 1  may be defined by a first sidewall SW 1 , the second hole portion  101 H 2  may be defined by a second sidewall SW 2 , and the third hole portion  101 H 3  may be defined by a third sidewall SW 3 . 
     The first hole portion  101 H 1 , the second hole portion  101 H 2 , and the third hole portion  101 H 3  may have different sizes from each other. For example, the first hole portion  101 H 1  may have the smallest size, the second hole portion  101 H 2  may have the largest size, and the third hole portion  101 H 3  may have a size between the sizes of the first and second hole portions  101 H 1  and  101 H 2 . 
     The first hole portion  101 H 1  may be formed by a laser cutting process. For example, a laser may be used to cut the layers from the lower protection film  400  to the second adhesive layer  1020 . The second hole portion  101 H 2  may be provided in the cushion member  500 , and in an exemplary embodiment, the second hole portion  101 H 2  may be formed by a shearing process on the cushion member  500 . The cushion member  500  with the second hole portion  101 H 2  may be attached to the lower protection film  400 . The third hole portion  101 H 3  may be formed by a shearing process on the plate  610  and the height-difference compensation member  800 . 
     According to an exemplary embodiment, the cushion member  500  with the second hole portion  101 H 2  may be attached to the plate  610  with the third hole portion  101 H 3 , and then, the cushion member  500  may be attached to the lower protection film  400 . Thus, the first hole portion  101 H 1 , the second hole portion  101 H 2 , and the third hole portion  101 H 3  may be formed to have different sizes from each other, in consideration of the part tolerance, the apparatus tolerance, and the folding tolerance. 
     The folding tolerance may be tolerance caused by the folding operation of the electronic device  1000 . For example, the folding tolerance may be determined in consideration of a movement distance (or slip) of each element, when the electronic device  1000  is fully folded, and an unrestored movement distance of each element, when the electronic device  1000  is unfolded after the folding operation. 
     According to an exemplary embodiment, since the sizes of the first hole portion  101 H 1 , the second hole portion  101 H 2 , and the third hole portion  101 H 3  are determined in consideration of the folding tolerance, any interference issue may not occur between an inner sidewall of the first hole  101 H and an electronic module (e.g., the camera module  2100 ) inserted in the first hole  101 H. In addition, the second light-blocking pattern  362 , which is provided to correspond to the position of the first hole  101 H, may also be disposed in consideration of the folding tolerance. Thus, even when the electronic device  1000  is folded and unfolded, it may be possible to reduce the probability that the second light-blocking pattern  362  veils the active region  100 A (e.g., see  FIG.  4 A ) of the display panel  100  or veils a view angle region  2100 AV of the camera module  2100 . 
     According to an exemplary embodiment, the second light-blocking pattern  362  may be directly disposed on the impact absorbing layer  370 , and the second hard coating layer  380  may be directly disposed under the impact absorbing layer  370 . Thus, the second light-blocking pattern  362  may be in contact with the impact absorbing layer  370 , and the second hard coating layer  380  may be in contact with the impact absorbing layer  370 . The impact absorbing layer  370  may be disposed between the second light-blocking pattern  362  and the second hard coating layer  380 . 
     The second light-blocking pattern  362  may be formed by a printing method, after forming the second hard coating layer  380  on the impact absorbing layer  370 . Since the impact absorbing layer  370  has an uneven and/or rough surface, compared with the second hard coating layer  380 , an adhesive strength may be stronger when the second light-blocking pattern  362  is printed on the impact absorbing layer  370  than when the second light-blocking pattern  362  is printed on the second hard coating layer  380 . Since the second light-blocking pattern  362  is directly printed on the uneven surface and/or rough surface of the impact absorbing layer  370 , the probability that the second light-blocking pattern  362  is detached from the impact absorbing layer  370  may be reduced. 
     The camera module  2100  may be inserted in the first hole  101 H. The second upper adhesive layer  350 , the light-blocking layer  360 , the impact absorbing layer  370 , and the second hard coating layer  380  may be disposed between the camera module  2100  and the window  340 . Since at least one layer is disposed between the camera module  2100  and the window  340 , the possibility that the window  340  is damaged by the camera module  2100  may be reduced. Accordingly, product reliability of the electronic device may be improved. 
     A top surface  2100 U of the camera module  2100  may be located in the second hole portion  101 H 2  provided in the cushion member  500 . The second hole portion  101 H 2  may have the largest diameter, among the first to third hole portions  101 H 1 ,  101 H 2 , and  101 H 3 . Thus, even when the positional relationship between layers is changed by the folding of the electronic device  1000 , the probability of the camera module  2100  colliding with the second sidewall SW 2  may be reduced. Accordingly, product reliability of the electronic device may be improved. 
     The position of the top surface  2100 U of the camera module  2100  is not limited to an example of  FIG.  6   . For example, the top surface  2100 U of the camera module  2100  may be disposed in the first hole portion  101 H 1 . In this case, the width  362 W of the region enclosed and/or completely surrounded by the second light-blocking pattern  362  may be designed to have a reduced value, compared with the case that the top surface  2100 U of the camera module  2100  is disposed in the second hole portion  101 H 2 . 
     For example, the second light-blocking pattern  362  may be designed, such that the second light-blocking pattern  362  is not overlapped with the view angle region  2100 AV of the camera module  2100 . When viewed in a plan view, the second light-blocking pattern  362  may be spaced apart from the view angle region  2100 AV of the camera module  2100  by a specific distance, in consideration of process tolerance. Since a distance between the camera module  2100  and the second light-blocking pattern  362  is reduced, the second light-blocking pattern  362  may not block or veil the view angle region  2100 AV of the camera module  2100 , even when the width  362 W of the region enclosed and/or completely surrounded by the second light-blocking pattern  362  is reduced. 
     According to an exemplary embodiment, the distance DT between the camera module  2100  and the window  340  may be maintained to a value that is greater than a predetermined distance. In the case where the distance DT between the camera module  2100  and the window  340  is maintained to be greater than the predetermined distance, the probability that the window  340  is damaged by the camera module  2100  may be reduced. Accordingly, product reliability of the electronic device may be improved. The damage may be a crack, when the window  340  is a glass substrate and may be a dent, when the window  340  is a synthetic resin film. 
     For example, the distance DT may range from 60% to 200% of the sum of thicknesses of elements, which have the first holes  101 H defined therein and have moduli smaller than a reference modulus. In  FIG.  6   , the elements with the first holes  101 H may correspond to elements that are disposed below the second hard coating layer  380 . The reference modulus may be less than 100 MPa, and in an exemplary embodiment, the reference modulus may range from 0 MPa to 50 MPa. 
     The elements satisfying such a condition may be the first adhesive layer  1010 , the second adhesive layer  1020 , the third adhesive layer  1030 , the first cushion adhesive layer  510 , the cushion layer  530 , the second cushion adhesive layer  540 , the first compensation adhesive layer  810 , and the second compensation adhesive layer  830 . 
     In an exemplary embodiment, The thickness of the first adhesive layer  1010  may be about 25 μm, the thickness of the second adhesive layer  1020  may be about 25 μm, the thickness of the third adhesive layer  1030  may be about 18 μm, the thickness of the first cushion adhesive layer  510  may be about 25 μm, the thickness of the cushion layer  530  may be about 100 μm, the thickness of the second cushion adhesive layer  540  may be about 8 μm, the thickness of the first compensation adhesive layer  810  may be about 17 μm, and the thickness of the second compensation adhesive layer  830  may be about 17 μm. Each of the thicknesses may have a process error. Thus, the sum of the thicknesses may range from 183 μm to 300 μm (in particular, about 235 μm). However, the sum of the thicknesses is not limited thereto. 
     The distance DT between the camera module  2100  and the window  340  may be determined in consideration of the highest compressibility of layers having moduli less than a reference modulus. For example, the distance DT may be greater than a value that is obtained by multiplying a sum of the thicknesses by the highest compressibility. The distance DT may be larger than 110 μm (e.g., larger than 141 μm). 
     According to an exemplary embodiment, even the elements are maximally compressed by pressure exerted during the usage of the electronic device  1000 , the window  340  and the camera module  2100  may be spaced apart from each other by a specific distance. Thus, the probability that the window  340  is damaged by the camera module  2100  may be significantly reduced. Accordingly, product reliability of the electronic device may be improved. 
       FIG.  7    is a plan view of an exemplary embodiment of the first to third sidewalls and the second light-blocking pattern of  FIG.  6   . 
     The second light-blocking pattern  362 , the first sidewall SW 1 , the second sidewall SW 2 , and the third sidewall SW 3  are exemplarily illustrated in  FIG.  7   . 
     When viewed in a plan view, the first sidewall SW 1  may overlap the second light-blocking pattern  362 , and the second sidewall SW 2  and the third sidewall SW 3  may not overlap the second light-blocking pattern  362 . When viewed in a plan view, the third sidewall SW 3  may enclose and/or completely surround the second light-blocking pattern  362 , and the second sidewall SW 2  may enclose and/or completely surround the third sidewall SW 3 . 
     Referring to  FIGS.  6  and  7   , the first width WT 1  of the first hole portion  101 H 1 , the second width WT 2  of the second hole portion  101 H 2 , and the third width WT 3  of the third hole portion  101 H 3  may be different from each other. For example, the second width WT 2  may be greater than the first width WT 1  and the third width WT 3 , and the third width WT 3  may be greater than the first width WT 1 . 
     An inner diameter  3621 D of the second light-blocking pattern  362  may range from 2 mm to 3 mm (in particular, about 2.68 mm), and an outer diameter  3620 D of the second light-blocking pattern  362  may range from 3.2 mm to 4.2 mm (in particular, about 3.72 mm). 
     Thus, the width  362 TW (e.g., see  FIG.  4 B ) of the second light-blocking pattern  362  may be about 0.52 mm. 
     The first hole portion  101 H 1  may correspond to a hole defined in the display panel  100 . When viewed in a plan view, a portion  362 P 1  of the second light-blocking pattern  362  may be disposed in the first hole portion  101 H 1 . In other words, the portion  362 P 1  of the second light-blocking pattern  362  may overlap the first hole portion  101 H 1 . In addition, another portion  362 P 2  of the second light-blocking pattern  362  may not overlap the first hole portion  101 H 1 . 
       FIG.  8    is a cross-sectional view taken along line III-III′ of  FIG.  1 A  to illustrate an exemplary embodiment of the electronic device. 
       FIG.  8    illustrates the third hole  103 H, in which the light-receiving module  2220  is inserted. The second hole  102 H (e.g., see  FIG.  5   ), in which the light-emitting module  2210  (e.g., see  FIG.  4 A ) is inserted, may have substantially the same sectional structure as the third hole  103 H, and thus, one may understand technical features associated with the second hole  102 H (e.g., see  FIG.  5   ) through the following description. 
     The third hole  103 H may include a first hole portion  103 H 1  and a second hole portion  103 H 2 . The first hole portion  103 H 1  may be defined by a first sidewall SW 13 , and the second hole portion  103 H 2  may be defined by a second sidewall SW 23 . 
     The first hole portion  103 H 1  and the second hole portion  103 H 2  may have different sizes from each other. For example, the size of the first hole portion  103 H 1  may be greater than the size of the second hole portion  103 H 2 . 
     The first hole portion  103 H 1  may be provided in the cushion member  500 , and in an exemplary embodiment, the first hole portion  103 H 1  may be formed by a shearing process on the cushion member  500 . The second hole portion  103 H 2  may be formed by a shearing process on the first lower member  600  and the second lower member  700 . 
     The third hole  103 H may not be provided in the display panel  100 . For example, the third hole  103 H may be provided in at least one of elements disposed below the display panel  100 . Thus, a portion of the display panel  100  overlapped with the third hole  103 H may display an image and may sense an input applied from the outside. 
     The first hole  101 H (e.g., see  FIG.  6   ) may penetrate the display panel  100 , but the third hole  103 H may not penetrate the display panel  100 . For example, the depth DT 1  of the first hole  101 H (e.g., see  FIG.  6   ) may be greater than a depth DT 2  of the third hole  103 H. 
       FIG.  9    is a cross-sectional view taken along line II-II′ of  FIG.  1 A  to illustrate another exemplary embodiment of the electronic device. In the following description of  FIG.  9   , an element previously described with reference to  FIG.  6    may be identified by the same reference number without repeating the description thereof to avoid redundancy. 
     Referring to  FIG.  9   , the second light-blocking pattern  362   a  of an electronic device  1000   aa  may be disposed between the window  340  and the first upper adhesive layer  330 . The first light-blocking pattern  361  (e.g., see  FIG.  4 A ) of the electronic device  1000   aa  may also be disposed between the window  340  and the first upper adhesive layer  330 . 
     The second light-blocking pattern  362   a  may be printed on a top surface of the window  340  and may be covered with the first upper adhesive layer  330 . The thickness of the second light-blocking pattern  362   a  may range from 0.5 μm to 1.5 μm (in particular, 1 μm). However, the thickness of the second light-blocking pattern  362   a  is not limited thereto. 
     According to an exemplary embodiment, the second light-blocking pattern  362   a  is disposed on the top surface of the window  340 , and it may be possible to reduce the probability that an uneven portion is formed in layers covering the second light-blocking pattern  362   a  since the second light-blocking pattern  362   a  has a relatively thin thickness. For example, the second light-blocking pattern  362   a  may have a thickness lower than that of another light-blocking pattern, such as the first light-blocking pattern  361  overlapping the peripheral region  1000 NA of  FIG.  1 A . Accordingly, it may be possible to prevent deterioration in the quality of an image obtained by the camera module  2100 . 
       FIG.  10    is a cross-sectional view taken along line II-II′ of  FIG.  1 A  to illustrate still another exemplary embodiment of the electronic device. In the following description of  FIG.  10   , an element previously described with reference to  FIG.  6    may be identified by the same reference number without repeating the description thereof to avoid redundancy. 
     Referring to  FIG.  10   , the second light-blocking pattern  362   b  of an electronic device  1000   bb  may be disposed between the second adhesive layer  1020  and the anti-reflection member  200 . The first light-blocking pattern  361  of the electronic device  1000   bb  (e.g., see  FIG.  4 A ) may be disposed between the second adhesive layer  1020  and the anti-reflection member  200 . The second light-blocking pattern  362   b  may constitute a portion of the first sidewall SW 1  defining the first hole portion  101 H 1 . 
     The second light-blocking pattern  362   b  may be printed on the anti-reflection member  200  and may be covered with the second adhesive layer  1020 . The thickness of the second light-blocking pattern  362   b  may range from 0.5 μm to 1.5 μm (in particular, about 1 μm). However, the thickness of the second light-blocking pattern  362   b  is not limited thereto. 
     According to an exemplary embodiment, the second light-blocking pattern  362   b  is disposed on the top surface of the anti-reflection member  200 , and it may be possible to reduce the probability that an uneven portion is formed in layers covering the second light-blocking pattern  362   b  since the second light-blocking pattern  362   b  has a relatively thin thickness. For example, the second light-blocking pattern  362   b  may have a thickness lower than that of another light-blocking pattern, such as the first light-blocking pattern  361  overlapping the peripheral region  1000 NA of  FIG.  1 A . Accordingly, it may be possible to prevent deterioration in the quality of an image obtained by the camera module  2100 . 
       FIG.  11    is a cross-sectional view taken along line II-II′ of  FIG.  1 A  to illustrate yet another exemplary embodiment of the electronic device. In the following description of  FIG.  11   , an element previously described with reference to  FIG.  6    may be identified by the same reference number without repeating the description thereof to avoid redundancy. 
     An electronic device  1000   cc  of  FIG.  11    may not include the impact absorbing layer  370 , the second hard coating layer  380 , and the second adhesive layer  1020  of  FIG.  6   , when compared with the electronic device  1000  described with reference to  FIG.  6   . In this case, the upper member  300  may be attached to the anti-reflection member  200  via the second upper adhesive layer  350 . In addition, the electronic device  1000   cc  may further include a second hard coating layer  341  disposed below the window  340 , when compared with the electronic device  1000  of  FIG.  6   . 
     The first hole  101 Ha may include the first hole portion  101 H 1   a,  the second hole portion  101 H 2 , and the third hole portion  101 H 3 . The first hole portion  101 H 1   a  may be defined by the first sidewall SW 1   a.  The first hole portion  101 H 1   a  may be formed by a laser cutting process. The first sidewall SW 1   a  may include sidewalls of the lower protection film  400 , the third adhesive layer  1030 , the display panel  100 , the first adhesive layer  1010 , the anti-reflection member  200 , and the second upper adhesive layer  350 . After the formation of the first hole  101 Ha, the second upper adhesive layer  350  may be attached to the second hard coating layer 
     The second hard coating layer  341  may be exposed by the first hole portion  101 H 1   a.  The bottom surface of the window  340  may be planarized by the second hard coating layer  341 . Since the second hard coating layer  341  covers the bottom surface of the window  340  to protect the window  340  against other elements of the electronic device  1000   cc,  such as the camera module  2100 , it may be possible to prevent the window  340  from damaged due to the other elements such as the camera module  2100 . 
     The second light-blocking pattern  362   c  may be disposed between the window  340  and the first upper adhesive layer  330 . The first light-blocking pattern  361  of the electronic device  1000   cc  (e.g., see  FIG.  4 A ) may be disposed between the window  340  and the first upper adhesive layer  330 . 
     The second light-blocking pattern  362   c  may be printed on the top surface of the window  340  and may be covered with the first upper adhesive layer  330 . The thickness of the second light-blocking pattern  362   c  may range from 0.5 μm to 1.5 μm (in particular, about 1 μm). However, the thickness of the second light-blocking pattern  362   c  is not limited thereto. 
     According to an exemplary embodiment, the second light-blocking pattern  362   c  is disposed on the top surface of the window  340 , and it may be possible to reduce the probability that an uneven portion is formed in layers covering the second light-blocking pattern  362   c  since the second light-blocking pattern  362   c  has a relatively small thickness. For example, the second light-blocking pattern  362   c  may have a thickness less than that of another light-blocking pattern, such as the first light-blocking pattern  361  overlapping the peripheral region  1000 NA of  FIG.  1 A . Accordingly, it may be possible to prevent deterioration in the quality of an image obtained by the camera module  2100 . 
       FIG.  12    is a cross-sectional view taken along line II-II′ of  FIG.  1 A  to illustrate still yet another exemplary embodiment of the electronic device. In the following description of  FIG.  12   , an element previously described with reference to  FIG.  6    may be identified by the same reference number without repeating the description thereof to avoid redundancy. 
     Referring to  FIG.  12   , an electronic device  1000   dd  may not include the second hard coating layer  380 , when compared with the electronic device  1000  described with reference to  FIG.  6   . 
     The second light-blocking pattern  362   d  may be disposed on the top or bottom surface of the impact absorbing layer  370 .  FIG.  12    illustrates an example, in which the second light-blocking pattern  362   d  is disposed on the bottom surface of the impact absorbing layer  370 . The second light-blocking pattern  362   d  may be disposed between the impact absorbing layer  370  and the second adhesive layer  1020 . 
     The distance between the camera module  2100  and the second light-blocking pattern  362   d  may be reduced, compared with the example of  FIG.  6   . Thus, the second light-blocking pattern  362   d  may not veil the view angle region  2100 AV of the camera module  2100 , even when the width  362 W of the region, which is enclosed and/or completely surrounded by the second light-blocking pattern  362   d,  is reduced. 
     The thickness of the second light-blocking pattern  362   d  may range from 0.5 μm to 1.5 μm (in particular, about 1 μm). However, the thickness of the second light-blocking pattern  362   d  is not limited thereto. According to an exemplary embodiment, it may be possible to reduce the probability that an uneven portion is formed in layers covering the second light-blocking pattern  362   d  since the second light-blocking pattern  362   d  has a relatively thin thickness. Accordingly, it may be possible to prevent deterioration in the quality of an image obtained by the camera module  2100 . 
       FIG.  13    is a cross-sectional view taken along line II-II′ of  FIG.  1 A  to illustrate another exemplary embodiment of the electronic device. In the following description of  FIG.  13   , an element previously described with reference to  FIG.  6    may be identified by the same reference number without repeating the description thereof to avoid redundancy. 
     Referring to  FIG.  13   , an electronic device  1000   ee  may differ from the electronic device  1000  described with reference to  FIG.  6    in terms of the position of the second light-blocking pattern  362   e.    
     The second light-blocking pattern  362   e  may be disposed below the second hard coating layer  380 . The second light-blocking pattern  362   e  may be disposed between the second adhesive layer  1020  and the second hard coating layer  380 . The first light-blocking pattern  361  (e.g., see  FIG.  4 A ) of the electronic device  1000   ee  may be disposed between the second adhesive layer  1020  and the second hard coating layer  380 . 
     The distance between the camera module  2100  and the second light-blocking pattern  362   e  may be reduced, compared with the example of  FIG.  6   . Thus, the second light-blocking pattern  362   e  may not veil the view angle region  2100 AV of the camera module  2100 , even when the width  362 W of the region, which is enclosed and/or completely surrounded by the second light-blocking pattern  362   e,  is reduced. 
     In addition, the thickness of the second light-blocking pattern  362   e  may range from 0.5 μm to 1.5 μm (in particular, 1 μm). However, the thickness of the second light-blocking pattern  362   e  is not limited thereto. According to an exemplary embodiment, it may be possible to reduce the probability that an uneven portion is formed in layers covering the second light-blocking pattern  362   e  since the second light-blocking pattern  362   e  has a relatively small thickness. For example, the second light-blocking pattern  362   e  may have a thickness less than that of another light-blocking pattern, such as the first light-blocking pattern  361  overlapping the peripheral region  1000 NA of  FIG.  1 A . Accordingly, it may be possible to prevent deterioration in the image quality of an image obtained by the camera module  2100 . 
     Although certain exemplary embodiments and implementations have been described herein, other embodiments and modifications will be apparent from this description. Accordingly, the inventive concepts are not limited to such embodiments, but rather to the broader scope of the appended claims and various obvious modifications and equivalent arrangements as would be apparent to a person of ordinary skill in the art.
