[0001] Cross-reference to related applications
[0002] This application claims priority and benefit to Korean Patent Application No. 10-2020-0042713, filed on April 8, 2020, which is incorporated herein by reference for all purposes as fully set forth herein. Technical Field
[0003] Exemplary embodiments of the present invention generally relate to display devices, and more specifically, to display devices including a support layer for a display panel. Background Technology
[0004] Various display devices have been developed for multimedia devices such as televisions, mobile phones, tablet computers, navigation systems, and game consoles. A display device may include a display module for displaying images and detecting external input, a polarizing layer on the display panel, and a window. A display module may include a display panel for displaying images and an input sensing unit for detecting external input.
[0005] Furthermore, the display device may include a protective plate disposed below and supporting the display panel, and a plurality of lower constituent layers below the protective plate. The display panel may include alignment marks, which can be used to align the lower constituent layers with the display panel. For example, the protective plate may be made of a metallic material, and the portion of the protective plate overlapping the alignment marks may be cut away to allow the alignment marks to be visible through the lower constituent layers.
[0006] The information disclosed in this background section is only for understanding the background technology of the inventive concept, and therefore may include information that does not constitute prior art. Summary of the Invention
[0007] The applicant recognizes that during the manufacturing of the display device, when the lower constituent layer is attached to the display panel, the cut-off area of the protective plate may not be able to protect the display panel.
[0008] A display device constructed according to the principles and exemplary embodiments of the present invention provides a support member to prevent the display panel from breaking, and markings such as alignment marks are visible through this support member. For example, the display device may include a support layer supporting a lower portion of the display panel. A first portion of the support layer may have a structure that overlaps with the alignment marks included in the display panel. Since the first portion of the support layer comprises a transparent material, the alignment marks are visible even when the support layer overlaps with the alignment marks. Therefore, when a lower constituent layer is joined below the support layer during manufacturing, the first portion of the support layer overlapping the alignment marks can prevent the display panel from being damaged by impact. Furthermore, the support layer can prevent the display panel from being subjected to impact when various inspection processes are performed during the joining process.
[0009] Additional features of the inventive concept will be set forth in the following description and will be apparent in part from the description or may be learned by practice of the inventive concept.
[0010] According to one aspect of the present invention, a display device includes: a substrate including a display area and a peripheral area adjacent to the display area; a mark on the substrate; and a support member below the substrate, wherein the support member includes: a first portion and a second portion adjacent to the first portion, the first portion overlapping the mark and including a transparent material, the second portion overlapping the display area; and a first adhesive layer between the substrate and the second portion.

[0018] The resin can have a structure aligned with the side surface of the substrate.
[0019] The second part can have essentially the same transparent material as the first part.
[0020] The first part and the second part may include different materials, and the support may include a support layer and may also include an auxiliary adhesive layer between the substrate and the first part, the auxiliary adhesive layer including a transparent material.
[0021] The stiffness of the second part can be greater than that of the first part.
[0022] The second part may include metallic materials.
[0023] The support may also include a resin that can overlap with the substrate, the resin at least partially covering the bottom surface of the substrate and the side surface of the support, wherein the resin may have a structure aligned with the side surface of the substrate.
[0024] The sub-support member may be located below the support member, wherein the sub-support member may include: a sub-plate that may overlap with the second portion; and a second adhesive layer between the sub-plate and the second portion.

[0028] The marker may include one or more alignment marks that overlap with the surrounding area.
[0029] According to another aspect of the invention, a display device includes: at least one alignment mark included in a display panel; and a support layer disposed below the display panel and supporting the display panel, wherein the support layer includes: a plate having a first portion and a second portion adjacent to the first portion, the first portion overlapping the alignment mark and including a transparent material; and an adhesive layer between the display panel and the second portion, the adhesive layer not overlapping the first portion.

[0050] In the following description, numerous specific details are set forth for purposes of explanation in order to provide a thorough understanding of various exemplary embodiments or embodiments of the invention. As used herein, “implementation” and “example” are interchangeable terms and are non-limiting examples of apparatus or methods employing one or more of the inventive concepts disclosed herein. However, it will be 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 apparatuses are illustrated in block diagram form to avoid unnecessarily obscuring the various exemplary embodiments. Furthermore, the various exemplary embodiments may be different, but are not necessarily exclusive. For example, a particular shape, configuration, and characteristic of an exemplary embodiment may be used or implemented in another exemplary embodiment without departing from the inventive concept.
[0051] Unless otherwise stated, the exemplary embodiments shown are to be understood as exemplary features providing details of variations in some ways in which the inventive concept can be implemented in practice. Therefore, unless otherwise stated, features, components, modules, layers, films, panels, regions and / or aspects (hereinafter individually or collectively referred to as “elements”) of various embodiments may be combined, separated, interchanged and / or rearranged in other ways without departing from the inventive concept.
[0052] Crosshairs and / or shading are typically used in the accompanying drawings to clarify the boundaries between adjacent elements. Therefore, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for a particular material, material properties, size, scale, commonalities between the elements shown, and / or any other characteristics, properties, etc., of the elements. Furthermore, the dimensions and relative dimensions of elements may be exaggerated in the accompanying drawings for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, the specific process sequence may be performed differently than the described sequence. For example, two consecutively described processes may be performed substantially simultaneously, or in the reverse order of their description. Furthermore, the same reference numerals denote the same elements.
[0053] When an element, such as a layer, is referred to as being "on," "connected to," or "attached to" another element or layer, it may be directly on, connected to, or attached to the other element or layer, or there may be an intermediate element or layer. However, when an element or layer is referred to as being "directly" on, directly connected to, or directly attached to another element or layer, there is no intermediate element or layer. Therefore, the term "connection" can refer to a physical connection, electrical connection, and / or fluid connection with or without an intermediate element. Furthermore, the D1-axis, D2-axis, and D3-axis are not limited to the three axes of a Cartesian coordinate system, such as the x-axis, y-axis, and z-axis, and can be interpreted in a broader sense. For example, the D1-axis, D2-axis, and D3-axis can be perpendicular to each other, or they 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, for example, 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.
[0054] 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. Therefore, without departing from the teachings of this disclosure, the first element discussed below may be referred to as the second element.
[0055] For descriptive purposes, spatial relative terms such as “below,” “under,” “below,” “lower,” “above,” “upper,” “above,” “higher,” “side,” (e.g., as in “sidewall”), etc., may be used herein to describe the relationship of one element to another (or multiple elements) as shown in the figures. In addition to the orientations depicted in the figures, spatial relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture. For example, if the device in the figures is flipped, an element described as being “below” or “under” other elements or features will consequently be oriented “above” other elements or features. Thus, the exemplary term “below” can encompass both above and below orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or in other orientations), and therefore the spatial relative descriptive terms used herein should be interpreted accordingly.
[0056] 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 also include the plural forms unless the context clearly indicates otherwise. Furthermore, when used in this specification, the terms “comprise,” “comprising,” “have,” “having,” “include,” and / or “including” indicate the presence of the described features, integrals, steps, operations, elements, components, and / or groups thereof, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, combinations, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than terms of degree, and therefore to explain the inherent deviations in measurements, calculated values, and / or provided values that would be recognized by one of ordinary skill in the art.
[0057] Various exemplary embodiments are described herein with reference to cross-sectional views and / or exploded views as schematic diagrams of idealized exemplary embodiments and / or intermediate structures. Therefore, variations in the shapes shown in the figures are contemplated, for example, due to manufacturing techniques and / or tolerances. Consequently, the exemplary embodiments disclosed herein should not be necessarily construed as limited to the shapes of the regions specifically shown, but will include deviations in shape, for example, due to manufacturing processes. In this way, the regions shown in the figures may be schematic in nature, and the shapes of these regions may not reflect the actual shapes of the regions of the device, and are therefore not necessarily intended to be limiting.
[0058] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. Terms, such as those defined in commonly used dictionaries, shall be interpreted as having a meaning consistent with their meaning in the context of the relevant field and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.
[0059] As used herein, the term “whole” means two or more parts or elements that form or function as a single unit or object.
[0060] Figure 1A This is a perspective view illustrating an exemplary embodiment of a display device constructed according to the principles of the present invention. Figure 1B This is a perspective view illustrating another exemplary embodiment of a display device constructed according to the principles of the present invention.
[0061] refer to Figure 1A The display device DD can display an image IM on the display surface DD-IS. An example of an image IM is shown: a clock window and an application icon. The display surface DD-IS includes a display area DD-DA on which the image IM is displayed and a peripheral area DD-NDA adjacent to the display area DD-DA. The peripheral area DD-NDA is an area on which no image is displayed.
[0062] For example, the peripheral region DD-NDA may surround the display region DD-DA. Alternatively, in some exemplary embodiments, the peripheral region DD-NDA may be configured to be adjacent only to one side of the display region DD-DA, or the peripheral region DD-NDA may not be configured at all.
[0063] The display surface DD-IS may have a shape extending along a first direction DR1 and a second direction DR2 intersecting the first direction DR1. The third direction DR3 represents the normal direction to the display surface DD-IS, or the thickness direction of the display device DD. As used herein, the phrase "when viewed in a plan view" or "when viewed in a plane" may mean "when viewed along the third direction DR3". The third direction DR3 distinguishes the front and rear surfaces (or top and bottom surfaces) of each layer or unit, which will be discussed below. However, the directions represented by the first direction DR1, the second direction DR2, and the third direction DR3 are relative concepts and may indicate opposite directions.
[0064] According to some exemplary embodiments, at least a portion of the display surface DD-IS may have a generally curved shape when viewed in a plan view. For example, at least one corner of the display surface DD-IS may have a generally curved shape when viewed in a plan view. Although at least one of the display surfaces DD-IS is exemplarily shown as having a generally curved shape, at least one of the outer edges of the display surface DD-IS may also have a generally curved shape.
[0065] When viewed in a plan view, a portion of the display device DD may include a generally cubic display surface. This generally cubic display surface may include multiple display areas DD-DA oriented in different directions, or a cylindrical display surface having a generally polygonal shape.
[0066] In some exemplary implementations, such as Figure 1A As shown, the display device DD can be used in a mobile phone terminal. The mobile phone terminal can be configured to include the display device DD in a bracket / housing that houses a motherboard on which electronic modules, camera modules, power modules, etc., are mounted. According to some exemplary embodiments, the display device DD can be applied not only to large electronic devices such as televisions and monitors, but also to small and medium-sized electronic devices such as tablet computers, car navigation systems, game consoles, and smartwatches.
[0067] refer to Figure 1B The display device DDA can include a display area DD-DA of a non-typical shape. For example, with Figure 1A Compared to the display area DD-DA, Figure 1B The display area DD-DA may further include a display segment whose shape has at least one side protruding in a first direction DR1. The display device DDA may include a speaker SIP and a camera module CMA configured to be adjacent to the protruding display segment.
[0068] The speaker SIP and camera module CMA are configured to overlap with the peripheral area DD-NDA but not with the display area DD-DA. Figure 1A The display device DD may also include a speaker SIP and a camera module CMA configured to overlap with the peripheral area DD-NDA. In some exemplary embodiments, the camera module CMA may be configured to have a structure that overlaps with the display area DD-DA.
[0069] Figure 1A and Figure 1BRigid display devices DD and DDa are shown, but according to some exemplary embodiments, at least one of the display devices DD and DDa may have flexible properties. For example, at least one of the display devices DD and DDa may be foldable about a folding axis or have a generally curved shape at least a portion thereof.
[0070] Figure 2 It is shown Figure 1A An exploded perspective view of the display device. Figure 3 This is a cross-sectional view illustrating an exemplary embodiment of a display module constructed according to the principles of the present invention.
[0071] refer to Figure 2 The display device DD may include a window WM, a display module DM, a driver chip DC, a circuit board PB, a support layer SP, and a housing component BC. The housing component BC can receive the display module DM and can be connected to the window WM.
[0072] The window WM can be positioned above the display module DM and can externally transmit images provided from the display module DM. The window WM includes a transmissive region TA and a non-transmissive region NTA. The transmissive region TA can overlap with the display regions DD-DA and can have a shape substantially corresponding to the shape of the display regions DD-DA. Figure 1A The image IM displayed in the display area DD-DA of the display device DD shown in the diagram is visible to the outside through the transmission area TA of the window WM.
[0073] The non-transmissive region NTA may overlap with the peripheral region DD-NDA and may have a shape substantially corresponding to the shape of the peripheral region DD-NDA. The non-transmissive region NTA may be a region whose optical transmittance is relatively less than that of the transmissive region TA. However, some exemplary embodiments are not limited to this and the non-transmissive region NTA may be omitted.
[0074] The window WM can be formed of glass, sapphire, or plastic. Although the window WM is shown as a single layer, it can comprise multiple layers. The window WM can include a base layer and at least one printed layer that overlaps with the non-transparent region NTA and is disposed on the back surface of the base layer. The printed layer can have a defined color. For example, the printed layer can be black or any color other than black.
[0075] The display module DM is positioned between the window WM and the receiving component BC. The display module DM includes a display panel DP and an input sensing layer ISU. The display panel DP can generate images and send the generated images to the window WM.
[0076] According to some exemplary embodiments, the display panel DP can be an emitting display panel and is not particularly limited in its type. For example, the display panel DP can be an organic light-emitting display panel or a quantum dot light-emitting display panel. The emitting layer of an organic light-emitting display panel can include organic light-emitting materials. The emitting layer of a quantum dot light-emitting display panel can include quantum dots or quantum rods. Examples in which an organic light-emitting display panel is used as the display panel DP will be discussed below.
[0077] The following describes examples of some exemplary embodiments in which an organic light-emitting display panel is used as the display panel DP. However, some exemplary embodiments are not limited thereto, and various types of display panels may be applied in some exemplary embodiments.
[0078] An input sensing layer (ISU) can be positioned between the window (WM) and the display panel (DP). The ISU detects externally applied input. Externally applied input can be provided in various types. For example, external input includes the user's body parts, a stylus, light, heat, pressure, or any other type of external input. Furthermore, external input can include not only the user's touch (such as the user's hand) but also spatial touches that are near or adjacent to the user (e.g., hover touch).
[0079] refer to Figure 3 The display panel DP includes a substrate SUB, a circuit element layer DP-CL, a display element layer DP-OLED, and a dielectric layer TFL. The display panel DP includes a display area DP-DA and a peripheral area DP-NDA. The display area DP-DA of the display panel DP is... Figure 1A The display area shown corresponds to or is related to DD-DA. Figure 2 The transmission region TA shown corresponds to the outer region DP-NDA of the display panel DP. Figure 1A The peripheral region shown corresponds to or is related to DD-NDA. Figure 2 The non-transmissive region NTA shown corresponds to this.
[0080] The substrate SUB may include at least one plastic film. The substrate SUB may include a flexible substrate, such as at least one selected from plastic substrates, glass substrates, metal substrates, and organic / inorganic composite substrates. The circuit element layer DP-CL includes circuit elements and at least one intermediate dielectric layer. The intermediate dielectric layer includes at least one intermediate inorganic layer and at least one intermediate organic layer. The circuit elements include signal lines and pixel driving circuitry.
[0081] The DP-OLED display element layer includes a plurality of organic light-emitting diodes. The DP-OLED display element layer may also include an organic layer such as a pixel defining layer. According to some exemplary embodiments, when the display panel DP is provided as a liquid crystal display panel, the DP-OLED display element layer may be provided as a liquid crystal layer.
[0082] A dielectric layer TFL encapsulates the display element layer DP-OLED. For example, the dielectric layer TFL can be a thin-film encapsulation layer. The dielectric layer TFL protects the display element layer DP-OLED from foreign substances such as moisture, oxygen, and dust particles. However, some exemplary embodiments are not limited to this, and the dielectric layer TFL can be replaced by an encapsulation substrate. In this case, the encapsulation substrate can be disposed opposite to the substrate SUB, and the circuit element layer DP-CL and the display element layer DP-OLED can be disposed between the encapsulation substrate and the substrate SUB.
[0083] The input sensing layer (ISU) can be directly disposed on the display panel (DP). As used herein, the phrase "A is directly disposed on B" means that no adhesive layer is disposed between A and B. In some exemplary embodiments, the input sensing layer (ISU) and the display panel (DP) can be manufactured in a continuous process. However, some exemplary embodiments are not limited to this. The input sensing layer (ISU) can be disposed as a separate panel and can be attached to the display panel (DP) via an adhesive layer.
[0084] Return to reference Figure 2 The driver chip DC can be located on the display panel DP, overlapping with the peripheral area DP-NDA. For example, in response to control signals sent from the circuit board PB, the driver chip DC can generate the drive signals required for the operation of the display panel DP. The driver chip DC can then send the generated drive signals to the circuit element layer DP-CL of the display panel DP.
[0085] The circuit board PB can be disposed at the end of the substrate SUB and can be electrically connected to the circuit element layer DP-CL. The circuit board PB can be rigid or flexible. For example, when the circuit board PB is flexible, it can be configured as a flexible printed circuit board. The circuit board PB may include timing control circuitry for controlling the operation of the display panel DP. The timing control circuitry may be provided in the form of an integrated circuit chip mounted on the circuit board PB. Furthermore, the circuit board PB may include input sensing circuitry for controlling the input sensing layer ISU.
[0086] A polarizing layer (POL) is disposed between the display module DM and the window WM. The polarizing layer POL can polarize external light incident through the window WM, and thus prevents the circuit components included in the display module DM from being externally visible. The display device DD may also include an adhesive layer between the polarizing layer POL and the input sensing layer ISU, and an adhesive layer between the polarizing layer POL and the window WM.
[0087] In some exemplary embodiments, the polarization layer POL can be omitted. In this case, the polarization layer POL can be replaced by a color filter layer between the window WM and the display module DM. The color filter layer can absorb external light incident from the outside and thus prevent circuit elements from being visible. The color filter layer can include filters that have different colors from each other.
[0088] The support layer SP can be positioned between the display module DM and the housing component BC. Figure 3 The substrate SUB shown is located beneath the substrate, thus supporting almost the entire display panel DP. The support layer SP may include the substrate layer supporting the display panel DP. Furthermore, the support layer SP prevents external light from incident onto the substrate SUB. The support layer SP may include a light-absorbing layer that absorbs external light. The light-absorbing layer may be colored, such as black. The substrate layer may support the light-absorbing layer. The support layer SP will be discussed in detail below.
[0089] Figure 4 This is a plan view illustrating an exemplary embodiment of a display panel constructed according to the principles of the present invention.
[0090] refer to Figure 4 The display panel DP may include a driver circuit GDC, multiple signal lines SGL, multiple signal pads DP-PD, multiple connection signal pads DP-CPD, and multiple pixels PX. Representative pixels PX are disposed in the display area DP-DA. Each pixel PX includes an organic light-emitting diode (OLED) and a pixel driver circuit connected to the OLED. The driver circuit GDC, signal lines SGL, signal pads DP-PD, connection signal pads DP-CPD, and pixel driver circuit may be included in... Figure 3 The circuit element layer DP-CL is shown.
[0091] The signal line SGL includes the gate line GL, data line DL, power line PL, and control signal line CSL. The gate line GL is connected to the corresponding pixel PX, and the data line DL is also connected to the corresponding pixel PX. The power line PL is connected to the pixel PX. The control signal line CSL provides control signals to the scan drive circuitry.
[0092] The driving circuit GDC sequentially outputs gate signals to multiple gate lines GL. The driving circuit GDC can also output different control signals to the pixel PX. The driving circuit GDC may include multiple thin-film transistors formed by, for example, a low-temperature polycrystalline silicon (LTPS) process and a low-temperature polycrystalline oxide (LTPO) process, where each of these processes is identical to the process used to form the driving circuitry for the pixel PX.
[0093] Signal lines SGL can overlap with the display area DP-DA and the peripheral area DP-NDA. Each signal line SGL may include a pad portion and a line portion that can be integrally formed together (i.e., forming a single integral shape). The line portion overlaps with the display area DP-DA and the peripheral area DP-NDA. The pad portion is connected to the end of the line portion. The pad portion is located in the peripheral area DP-NDA and overlaps with a corresponding one of the signal pads DP-PD.
[0094] The peripheral region DP-NDA may have a chip region NDA-DC defined in its section by a signal pad DP-PD thereon, and also has a first pad region NDA-PC1 defined in its section by a connection signal pad DP-CPD thereon.
[0095] Figure 2 The driver chip DC shown can be mounted on the chip area NDA-DC. The signal pad DP-PD is electrically connected to the driver chip DC and provides the electrical signal received from the driver chip DC to the signal line SGL.
[0096] The signal pads DP-PD include a first row of signal pads DP-PD1 arranged in a first row along a first direction DR1 and a second row of signal pads DP-PD2 arranged in a second row along the first direction DR1. However, the exemplary embodiment is not limited thereto, and the signal pads DP-PD may be arranged in a single row along the first direction DR1.
[0097] A portion of the circuit board PB can be located on the first pad area NDA-PC1. The connection signal pad DP-CPD is electrically connected to the circuit board PB and provides the signal pad DP-PD with the electrical signals received from the circuit board PB. The circuit board PB can be rigid or flexible. For example, when the circuit board PB is flexible, it can be configured as a flexible printed circuit board.
[0098] The circuit board PB may include timing control circuitry for controlling the operation of the display panel DP. The timing control circuitry may be configured as an integrated circuit chip mounted on the circuit board PB. Furthermore, the circuit board PB may include input sensing circuitry for controlling the input sensing layer ISU. The circuit board PB may include a drive pad PB-PD electrically connected to the display panel DP. The drive pad PB-PD may be located on a second pad area NDA-PC2 defined on the circuit board PB.
[0099] According to some exemplary embodiments, the display panel DP may include at least one mark, which may have the form of an alignment mark AK. Although Figure 4 Six alignment marks AK are shown that overlap with the edge of the substrate SUB, but the number of alignment marks AK is not limited to this and can include any suitable number.
[0100] The display device DD may also include multiple lower constituent layers between the support layer SP and the receiving member BC. For example, the lower constituent layers may include a heat-radiating layer, a buffer layer, and a metal layer. The alignment mark AK may be an indicator mark for precise alignment of the lower constituent layers with the display panel DP. For example, the alignment mark AK may allow the lower constituent layer to occupy a desired position below the display panel DP.
[0101] According to some exemplary embodiments, the alignment mark AK can be disposed on the substrate SUB and overlap with the peripheral region DP-NDA. Figure 4 An alignment mark AK is exemplarily shown located near the edge of the substrate SUB, but the substrate SUB may have the alignment mark AK on any other segment that overlaps with the peripheral region DP-NDA. As used herein, the alignment mark AK is shown to overlap with the peripheral region DP-NDA on the substrate SUB, but at least one of the plurality of alignment marks AK may overlap with the display region DP-DA.

Figure 5B This is a plan view illustrating another exemplary embodiment of a support layer constructed according to the principles of the present invention. Figure 5C This is a plan view illustrating yet another exemplary embodiment of a support layer constructed according to the principles of the present invention. Figure 6 yes Figure 1A Exemplary implementations of display devices along Figure 5A A partial sectional view taken from line II′.
[0103] refer to Figure 5AThe support layer SP may include a first region LTA and a second region LSA. As used herein, the first region LTA of the support layer SP represents the area through which light can pass, and the second region LSA of the support layer SP indicates the area through which light cannot pass.
[0104] The support layer SP can be set as follows: Figure 3 The alignment mark AK is shown below the substrate SUB and is visible through the first region LTA. For example, the alignment mark AK can be seen through the rear surface of the support layer SP that overlaps with the first region LTA. To enable identification of the alignment mark AK, the substrate SUB may include a transparent material, and the components between the substrate SUB and the alignment mark AK may also include a transparent material. For example, at least one transparent dielectric layer may be disposed between the substrate SUB and the alignment mark AK.
[0105] refer to Figure 5B The alignment mark AK can have a structure that overlaps with the corner portion of the support layer SP. For example, Figure 5A The support layer SP shown can have a structure that overlaps with the six alignment marks AK, and Figure 5B The support layer SP shown can have a structure in which the four alignment marks AK overlap at the corner portions of the support layer SP.
[0106] refer to Figure 5C When viewed in a plan view, the alignment mark AK, according to some exemplary embodiments, can have various shapes. Figure 5C The alignment mark AK shown can have the same as Figure 5A or Figure 5B The alignment mark AK shown has different shapes. For example, according to Figure 5C As shown, the alignment mark AK is depicted as a bilaterally symmetrical triangle. In some exemplary embodiments, reference... Figure 5A and Figure 6 The support layer SP includes a plate TM and an adhesive layer AM.
[0107] The board TM can support the display panel DP and overlaps with both the first region LTA and the second region LSA. The board TM can have a first portion corresponding to the first region LTA and a second portion corresponding to the second region LSA. The second portion of the board TM corresponding to the second region LSA can support the display panel DP and... Figure 4 The display areas DP-DA shown are almost entirely overlapping. Furthermore, the second portion of the board TM, corresponding to the second region LSA, can support the display panel DP. Figure 4 The peripheral region shown overlaps with at least a portion of the DP-NDA.
[0108] According to some exemplary embodiments, the panel TM may include a transparent material. For example, the panel TM may include polyethylene terephthalate (PET) or polyethylene naphthalate (PEN). Because the panel TM is made of a transparent material, the alignment mark AK included in the display panel DP is visible through a first portion of the panel TM, which overlaps with the first region LTA. Therefore, the lower constituent layer below the support layer SP can be aligned with the display panel DP through the first portion of the panel TM.
[0109] according to Figure 6 In the embodiment shown, the first and second portions of the plate TM can be arranged as a single layer. When a plate is made of a rigid metal material, it has a structure that does not overlap with the alignment mark AK in order to identify the alignment mark AK. For example, the plate can be cut off at the portion (e.g., the edge) where it overlaps with the alignment mark AK. In this case, the edge of the plate (e.g., the cut-off portion) can provide an impact to the display panel DP during the process of attaching the lower constituent layer to the support layer SP. For this reason, the display panel DP may be partially damaged.
[0110] According to some exemplary embodiments, the first portion of the board TM corresponding to the first region LTA may have a structure that overlaps with the alignment mark AK included in the display panel DP. For example, as described above, even when the board TM overlaps with the alignment mark AK, the board TM may have a structure that allows the alignment mark AK to be externally visible. Therefore, during the process of attaching the lower constituent layer to the support layer SP, the first portion of the board TM can prevent impacts on the display panel DP corresponding to the first region LTA. Furthermore, since the board TM comprises a material such as polyethylene terephthalate (PET) whose stiffness is less than that of metallic materials, the display panel DP may be less likely to be damaged.
[0111] An adhesive layer AM can be disposed between the second portion of the display panel DP and the board TM. The adhesive layer AM can overlap with the second region LSA and can attach the display panel DP and the board TM to each other. For example, the adhesive layer AM can be a pressure-sensitive adhesive film (PSA). Because the adhesive layer AM has a structure that overlaps with the second region LSA, a gap space OP can be defined between the first portion of the display panel DP and the board TM.
[0112] The adhesive layer AM can be colored to absorb external light. In some exemplary embodiments, the adhesive layer AM can be black to absorb light with a wide wavelength range. Because the adhesive layer AM overlapping the second region LSA is black, the adhesive layer AM can suppress the display panel DP from receiving light incident through the board TM. Therefore, the circuitry of the display panel DP can be prevented from being externally visible.
[0113] Figure 7 This illustrates the construction based on the principles of the present invention. Figure 1A A plan view of another supporting layer. Figure 8A yes Figure 1A Another exemplary embodiment of the display device along Figure 7 A partial sectional view taken from line II-II′. Figure 8B yes Figure 1A Another exemplary embodiment of the display device along Figure 7 A partial sectional view taken from line II-II′.
[0114] Figure 7 The support layer SP-1 shown can have the same characteristics as... Figure 5A The structure of the support layer SP shown is basically the same as that of the support layer SP-1, except that the support layer SP-1 includes auxiliary adhesive layers AMs. Therefore, reference will be made below. Figure 7 and Figure 8A Describe in detail the configuration of the auxiliary adhesive layers (AMs).
[0115] refer to Figure 8A The adhesive layer AM-1 overlapping the second region LSA may comprise a material different from that of the auxiliary adhesive layers AMs overlapping the first region LTA. For example, the adhesive layer AM-1 overlapping the second region LSA may be an adhesive film with a color for absorbing light, and the auxiliary adhesive layers AMs overlapping the first region LTA may be adhesive films that allow light to pass through. The board TM-1 may be provided as a single, integral unit.
[0116] For example, adhesive layer AM-1 can be disposed between plate TM-1, which overlaps with the second region LSA, and display panel DP. Auxiliary adhesive layers AMs can be disposed between plate TM-1, which overlaps with the first region LTA, and display panel DP. Auxiliary adhesive layers AMs may include a transparent material. Therefore, the alignment mark AK of display panel DP can be seen through the lower portion of plate TM-1 that overlaps with the first region LTA. For example, auxiliary adhesive layers AMs may be optically clear adhesive (OCA) film, optically clear resin (OCR), or pressure-sensitive adhesive (PSA) film.
[0117] and Figure 8A Compared to the TM-1 board shown, Figure 8B The plates TM-1s shown may include portions with different stiffnesses. For example, the plates TM-1s may include a first portion TM-1a that overlaps with the first region LTA and has a first stiffness, and a second portion TM-1b that overlaps with the second region LSA and has a second stiffness. The first portion TM-1a may be positioned below the display panel DP that overlaps with the alignment mark AK.
[0118] According to some exemplary embodiments, the second stiffness of the second part TM-1b can be greater than the first stiffness of the first part TM-1a. In some exemplary embodiments, such as Figure 8B As shown, the second part TM-1b can support almost the entire display panel DP. The first part TM-1a can be the area for identifying the alignment mark AK, and can have a smaller planar area than the second part TM-1b.
[0119] Various methods can be provided to form a plate TM-1s comprising a first portion TM-1a and a second portion TM-1b having different stiffnesses from each other. For example, the stiffness of the first portion TM-1a and the second portion TM-1b can be adjusted by controlling the amount or duration of ultraviolet light irradiating the first portion TM-1a and the second portion TM-1b of the plate TM-1s. The first portion TM-1a and the second portion TM-1b of the plate TM-1s can be transparent, but the second portion TM-1b of the plate TM-1s can have an opacity that depends on its stiffness. Conversely, the first portion TM-1a of the plate TM-1s can have a stiffness whose extent falls within the range in which the alignment mark AK is visible.

[0121] Figure 9 The support layer SP-2 shown can have the same characteristics as... Figure 8A The structure of the support layer SP-1 shown is essentially the same as that of the previous one, except that the plate TM-2 is configured differently. Therefore, reference will be made below. Figure 9 Detailed description of the TM-2 board configuration.
[0122] refer to Figure 9 The panel TM-2 includes a first portion P1 and a second portion P2, which are made of different materials. The first portion P1 may be positioned below the display panel DP, overlapping with the alignment mark AK. The first portion P1 may include a transparent material such as polyethylene terephthalate (PET), and the second portion P2 may include a metallic material.
[0123] As referenced above Figure 8BThe second part P2 of the TM-2 discussed here can support almost the entire display panel DP. For example, since the display panel DP is supported by the second part P2, which has a stiffness greater than that of the first part P1, the display panel DP can be effectively protected from external impacts or the bonding process of the underlying constituent layers.
[0124] Figure 9 The diagram shows that the first part P1 and the second part P2 are in contact with each other, but depending on the process, the first part P1 and the second part P2 can be spaced apart from each other at a certain interval.
[0125] The adhesive layer AM-2 can be disposed between the second portion P2, which overlaps with the second region LSA, and the display panel DP. Similarly, as with the various embodiments discussed above, the adhesive layer AM-2 can be colored, but the exemplary embodiments are not limited thereto. For example, the adhesive layer AM-2 can comprise the same transparent material as the transparent material of the auxiliary adhesive layers AMs-2. Since the second portion P2, which includes a metallic material, shields or reflects external light, the adhesive layer AM-2 can be made of a transparent material.
[0126] Figure 10 It shows that Figure 2 The polarizing layer POL shown is connected to the display panel DP via a module adhesive layer ALY. The module adhesive layer ALY can be an optically transparent adhesive (OCA) film, an optically transparent resin (OCR), or a pressure-sensitive adhesive (PSA) film.
[0127] and Figure 9 Compared to the exemplary embodiment shown, the support layer SP-2a may further include resin RM. The resin RM may overlap with the first region LTA and may support the side surface of the board TM-2 and the display panel DP, which does not overlap with the auxiliary adhesive layer AMs-2.
[0128] like Figure 10 As shown, the display panel DP overlapping the first region LTA includes a portion not supported by the first portion P1 of the board TM-2. The resin RM can support the unsupported portion of the display panel DP, and thus the reliability of the display device DD can be increased.
[0129] According to some exemplary embodiments, resin RM can align the side surfaces of the support layer SP-2a, the display panel DP, and the polarizing layer POL. The polarizing layer POL has a first side surface POL-S1 and a second side surface POL-S2 facing each other in a second direction DR2. The display panel DP has a first side surface DP-S1 and a second side surface DP-S2 facing each other in the second direction DR2. The support layer SP-2a has a first side surface SP2-S1 and a second side surface SP2-S2 facing each other in the second direction DR2.
[0130] The first side surface POL-S1 of the polarizing layer POL, the first side surface DP-S1 of the display panel DP, and the first side surface SP2-S1 of the support layer SP-2a can be aligned with each other in the third direction DR3. The second side surface POL-S2 of the polarizing layer POL, the second side surface DP-S2 of the display panel DP, and the second side surface SP2-S2 of the support layer SP-2a can be aligned with each other in the third direction DR3. The support layer SP-2a, the display panel DP, and the polarizing layer POL can have side surfaces that face each other in the first direction DR1 and are aligned with each other in the third direction DR3. According to some exemplary embodiments, the resin RM can have a structure for supporting a portion of the display panel DP that is not supported by the first portion P1 of the plate TM-2, and the shape of the resin RM can be varied.
[0131] Figure 11A and Figure 11B yes Figure 1A The display device is still in some exemplary implementations along Figure 7 A partial sectional view taken from line II-II′.
[0132] Figure 11A This illustrates a state where there is no alignment between the side surfaces of the polarization layer POLm, the display panel DPm, the module adhesive layer ALYm, and the support layer SP-3m. Figure 11B The alignment is shown between the side surfaces of the polarization layer POL, the display panel DP, the module adhesive layer ALY, and the support layer SP-3.
[0133] refer to Figure 11A The diagram shows an unformed polarizing layer POLm, display panel DPm, module adhesive layer ALYm, and support layer SP-3m. The preformed polarizing layer POLm, preformed display panel DPm, preformed module adhesive layer ALYm, and preformed support layer SP-3m may have side surfaces that are misaligned with each other on a third-direction DR3.
[0134] According to some exemplary embodiments, the polarizing layer POLm, the display panel DPm, and the support layer SP-3m can be partially removed simultaneously to align their side surfaces with each other. For ease of description, the description of the module adhesive layer ALYm is omitted. Figure 11A As shown, each of the polarization layer POLm, the display panel DPm, and the support layer SP-3m includes a cut-off region CA that will be at least partially removed.
[0135] For example, a laser LR can be used to remove each of the polarization layer POLm, the display panel DPm, and the support layer SP-3m at its cut-off region CA. Therefore, as... Figure 11BAs shown, the already formed polarizing layer POL, display panel DP, and support layer SP-3 can have their side surfaces aligned with each other on the third direction DR3. For example, the first side surface POL-S1 of the polarizing layer POL, the first side surface DP-S1 of the display panel DP, and the first side surface SP3-S1 of the support layer SP-3 can be aligned with each other on the third direction DR3. The second side surface POL-S2 of the polarizing layer POL, the second side surface DP-S2 of the display panel DP, and the second side surface SP3-S2 of the support layer SP-3 can be aligned with each other on the third direction DR3.
[0136] The support layer SP-3 and the plate TM-3 can be integrally formed together, i.e., have a single-layer shape. For example, the plate TM-3 can have side surfaces corresponding to the side surfaces SP3-S1 and SP3-S2 of the support layer SP-3, and the side surfaces of the plate TM-3 can be aligned with the display panel DP and the polarizing layer POL. Therefore, with Figure 10 The difference shown Figure 11B The support layer SP-3 shown may not include a separate resin supporting the display panel DP. The adhesive layer AM-3 may have a similar structure to... Figure 9 or Figure 10 The structure of the adhesive layer AM-2 shown is essentially the same as that of the auxiliary adhesive layer AMs-3, and similarly, the auxiliary adhesive layer AMs-3 can have the same structure as the AM-2 shown. Figure 9 or Figure 10 The structure of the auxiliary adhesive layer AMs-2 shown is basically the same.
[0137] Figure 12 This is a perspective view showing yet another support layer constructed according to the principles of the present invention. Figure 13 This is still another exemplary embodiment of a display device constructed according to the principles of the present invention. Figure 12 A partial sectional view taken from line III-III′. Figure 14 This is yet another exemplary embodiment of a display device constructed according to the principles of the present invention. Figure 12 A partial sectional view taken from line III-III′.
[0138] refer to Figure 12 The support layer SP-4 includes a first support layer TMz and a second support layer NTM. The first support layer TMz includes a first adhesive layer T-P1 and a first plate T-P2. The second support layer NTM includes a second adhesive layer N-P1 and a second plate N-P2. The first support layer TMz can be disposed between the display panel DP and the second support layer NTM. As used herein, the second support layer NTM can be referred to as a sub-support layer, and the second plate N-P2 can be referred to as a sub-plate.
[0139] refer to Figure 13The first support layer TMz can have a larger planar area than the second support layer NTM. The first support layer TMz can support almost the entirety of the display panel DP that overlaps with the first region LTA and the second region LSA, and the second support layer NTM can support the first support layer TMz that overlaps with the second region LSA.
[0140] According to some exemplary embodiments, each of the first adhesive layer T-P1 and the first plate T-P2 may overlap with the first region LTA and the second region LSA. For example, each of the first adhesive layer T-P1 and the first plate T-P2 may include a transparent material. In some exemplary embodiments, the first adhesive layer T-P1 and the first plate T-P2 may be configured to... Figure 8A The structure of the support layer SP-1 shown is the same. (Reference) Figure 13 The first adhesive layer T-P1 is shown as comprising a transparent adhesive material, but as in Figure 8A As discussed herein, the first adhesive layer T-P1 may have a colored adhesive material at the portion of its location corresponding to the second region LSA.
[0141] The second adhesive layer N-P1 of the second support layer NTM can overlap with the second region LSA and can be disposed between the first plate T-P2 and the second plate N-P2. The second adhesive layer N-P1 can be colored and can absorb external light. For example, the second adhesive layer N-P1 can be black. The second plate N-P2 can include a metallic material and can be attached to the bottom surface of the second adhesive layer N-P1.
[0142] According to some exemplary embodiments, a second support layer NTM can be disposed below and overlap with the first support layer TMz, thereby supporting the display panel DP. For example, the second plate N-P2 can have a higher stiffness than the first plate T-P2. Therefore, the second support layer NTM can strongly support the second region LSA or the display area (see [link to documentation]). Figure 3 The corresponding display panel DP (DP-DA).
[0143] and Figure 13 Compared to the exemplary implementation shown, Figure 14 The support layer SP-4s also includes a protective layer PM and a third adhesive layer AMz. The protective layer PM can be disposed below the second support layer NTM. The protective layer PM may include a transparent material and can prevent foreign matter from being transferred to the display panel DP and the support layer SP-4s.
[0144] The third adhesive layer AMz may overlap with the first region LTA and may be disposed between the first plate T-P2 and the protective layer PM. The third adhesive layer AMz may include a transparent adhesive material. For example, since the transparent material is included in each of the first adhesive layer T-P1, the first plate T-P2, the third adhesive layer AMz, and the protective layer PM that overlap with the first region LTA, the alignment mark AK may be visible from the underside of the protective layer PM. Furthermore, the third adhesive layer AMz may align its side surface with the side surfaces of the first support layer TMz and the protective layer PM in a third direction DR3.
[0145] According to some exemplary embodiments, a display device may include a support layer that supports a lower portion of a display panel. For example, a first portion of the support layer has a structure that overlaps with alignment marks included in the display panel. Because the first portion of the support layer comprises a transparent material, the alignment marks can be visible even when the support layer overlaps with the alignment marks.
[0146] Therefore, during the manufacturing process of attaching the lower constituent layer to the support layer, the first portion of the support layer that overlaps with the alignment marks can prevent the display panel from being impacted. Furthermore, the support layer can prevent the display panel from being impacted when various inspection processes are performed during the attachment process.
[0147] Although certain exemplary embodiments and examples have been described herein, other embodiments and modifications will be apparent from this description. Therefore, the inventive concept is not limited to such embodiments, but is limited to the broader scope of the appended claims and various obvious modifications and equivalent arrangements, as will be apparent to those skilled in the art.
