[0036] Figures 13 to 17 It is according to the implementation method along Figure 5 A cross-sectional view taken from line VI-VI' in the display device. Detailed Implementation

[0037] In the following, embodiments of the present invention will be described in detail with reference to the accompanying drawings, enabling those skilled in the art to readily practice the present invention within the scope of their art. The present invention can be implemented in several different forms and is not limited to the embodiments described herein.

[0038] To clearly describe this utility model, parts that are not explained or related have been omitted, and the same reference numerals are used for the same or similar parts throughout the specification.

[0039] Furthermore, for better understanding and ease of description, the dimensions and thicknesses of each component shown in the accompanying drawings are arbitrarily illustrated, and therefore the present invention is not necessarily limited to what is shown. In the drawings, the thicknesses of layers, films, panels, regions, etc., are exaggerated for clarity. Additionally, in the accompanying drawings, the thicknesses of some layers and regions are exaggerated for better understanding and ease of description.

[0040] It will be understood that when an element, such as a layer, film, region, or substrate, is referred to as being associated with another element, such as being “on” another element, it may be directly on the other element, or there may be an intervening element. Conversely, when an element is referred to as being associated with another element, such as being “directly” on another element, there is no intervening element.

[0041] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or part from another. Therefore, without departing from the teachings herein, “first element,” “first component,” “first region,” “first layer,” or “first part” discussed below may be referred to as a second element, second component, second region, second layer, or second part.

[0042] Furthermore, throughout the instruction manual, the term "on" the target element will be understood to mean located above or below the target element, and not necessarily to mean "located on the upper side" based on the direction opposite to the direction of gravity.

[0043] Furthermore, relative terms such as “lower” or “bottom” and “upper” or “top” are used herein to describe the relationship between one element and another as shown in the figures. It will be understood that, in addition to the orientations depicted in the figures, relative terms are intended to also include different orientations of the device. For example, if a device in one of the figures is flipped, an element described as being “below” the other elements will be oriented to be “above” the other elements. Thus, the term “lower” can include both “lower” and “upper” orientations, depending on the specific orientation of the figure. Similarly, if a device in one of the figures is flipped, an element described as being “below” or “under” the other elements will be oriented to be “above” the other elements. Thus, the term “below” or “under” can include both “above” and “below” orientations.

[0044] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, “a,” “an,” “the,” and “at least one” do not indicate a limitation of quantity and are intended to include both the singular and the plural unless the context clearly indicates otherwise. Thus, reference to “a” element following “the” element in a claim includes one element and multiple elements. For example, “a element” has the same meaning as “at least one element” unless the context clearly indicates otherwise. “At least one” should not be construed as limiting “a” or “an.” “Or” means “and / or.” As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0045] Furthermore, unless explicitly stated otherwise, the word “including” and variations such as “comprising” or “including” will be understood to imply inclusion of the stated element, but not exclusion of any other element.

[0046] Furthermore, throughout the instruction manual, the phrase "in a plane" refers to the target portion as viewed from above, while the phrase "in a cross section" refers to the cross section formed by vertically cutting the target portion from the side.

[0047] Unless otherwise defined, 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 invention pertains. It will be further understood that terms such as those defined in commonly used dictionaries shall be interpreted as having the same meaning as they have in the context of the relevant technology and this invention, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0048] Embodiments are described herein with reference to cross-sectional illustrations as illustrative examples of idealized embodiments. Therefore, variations in the illustrated shapes due to, for example, manufacturing techniques and / or tolerances are to be expected. Consequently, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but should include, for example, shape deviations due to manufacturing processes. For example, regions shown or described as flat may generally have rough and / or non-linear characteristics. Furthermore, acute angles shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to illustrate precise shapes of the regions, nor are they intended to limit the scope of the claims.

[0049] The display device according to this embodiment will be described in detail below with reference to the accompanying drawings. Figure 1 A cross-section of a display device according to this embodiment is shown schematically. (Reference) Figure 1 The display device according to this embodiment may include a display panel DP and a cover glass CG disposed on the display panel DP. A polarizing layer 20 may be disposed between the display panel DP and the cover glass CG, and an adhesive layer 30 may be disposed on the polarizing layer 20. The display panel DP and the cover glass CG can be bonded to each other through the adhesive layer 30. The integrated display panel may include the display panel DP and the polarizing layer 20. Here, the cover glass CG may (e.g., at the polarizing layer 20) contact the integrated display panel. When in contact, elements or layers may form an interface between them.

[0050] In this embodiment, the various components or layers of the display device and its stacked structure can be arranged in a plane defined by a first direction and a second direction that intersect each other. The thickness direction of the display device and its various components or layers can be defined along a third direction that intersects the plane.

[0051] The adhesive layer 30 may include an optically transparent resin (OCR). In this case, the adhesive layer 30 can be formed or provided by coating the OCR material with an inkjet device and then curing the material and using the cured OCR as the adhesive layer 30.

[0052] Figure 2A and 2B The diagram schematically illustrates a method for providing a display device, including the coating and curing of OCR. (Reference) Figure 2A First, uncured OCR material is coated onto a stacked structure including the display panel DP and the polarizing layer 20. In this case, a nozzle 700 can be used to coat the uncured OCR material. In this embodiment, Figure 2A The stacked structure shown can be positioned relative to nozzle 700 (by... Figure 2A (The arrow indicates the relationship between the stacked structure and nozzle 700).

[0053] Although not shown, the stacked structure of material having OCR from nozzle 700 can be further configured relative to the light source (e.g., below ultraviolet (UV) light source 800). Here, relative to Figure 2A As shown in the vertical direction, the stacked structure can be below the nozzle 700 and the UV light source 800.

[0054] For example, by using a curing process with a UV light source 800 and placing a stacked structure of uncured OCR material in the path of the UV light, a first adhesive layer 31 with cured OCR material can be formed on the polarization layer 20. The first process for providing a display device may include... Figure 2A The image shows the transition from the first stacked structure (20 and DP as the initial stacked structure) to the second stacked structure (20, 31 and DP as the intermediate stacked structure), including the nozzle 700 and the UV light source 800 located therebetween.

[0055] Then, refer to Figure 2B In the second process of providing the display device, the OCR material is coated again, this time onto the second stacked structure provided in the first process. Specifically, the OCR material is applied to the edge portion of the display panel DP, which has a first cured layer (e.g., a first adhesive layer 31), using a nozzle 700, and the OCR material is cured using a UV light source 800, similar to the process described above. Figure 2A As depicted in the image.

[0056] Through this second process, a second adhesive layer 32, serving as a second curing layer, can be formed at the edges to provide a third stacked structure (20, DP, 31, and 32). Although Figure 2BA second adhesive layer 32 protruding on the left and right sides of the third stacked structure (e.g., opposite sides spaced apart in the first direction) is shown, but it will be understood that the second adhesive layer may be disposed along other sides of the third stacked structure opposite to each other in the second direction. In embodiments, the pattern of the second adhesive layer 32 may be disposed along the entire edge of the underlying stacked structure, and is not limited thereto.

[0057] like Figure 2A and Figure 2B As shown, the first adhesive layer 31 and the second adhesive layer 32 can together form the adhesive layer 30. Figure 2A and Figure 2B In this illustration, the boundaries of the first adhesive layer 31 and the second adhesive layer 32 are shown as distinct, but this is for better understanding and ease of description, and in the embodiment, the first adhesive layer 31 and the second adhesive layer 32 may comprise the same material. Therefore, the boundary between the first adhesive layer 31 and the second adhesive layer 32 may be invisible.

[0058] Figure 3 The planar shapes of the first adhesive layer 31 and the second adhesive layer 32 are schematically shown. Although not explicitly shown, Figure 4 The cross-sections of the first adhesive layer 31 and the second adhesive layer 32 relative to the display panel DP are schematically shown. Figure 4 The display panel DP indicated in the text can represent Figure 1 The display panel DP, including the polarization layer 20, is shown in the image, but the polarization layer 20 is omitted for clarity. That is, the display panel DP, including the polarization layer 20, is shown in the image. Figures 1 to 4 When combined, the adhesive layer 30 can contact the polarization layer 20, for example, to form an interface between them, or it can contact the display panel DP (for example, at the polarization layer 20 of the display panel DP or at another layer).

[0059] exist Figure 4 In this illustration, the boundaries of the first adhesive layer 31 and the second adhesive layer 32 are shown as distinct, but this is for better understanding and ease of description. Furthermore, in the implementation, the first adhesive layer 31 and the second adhesive layer 32 may comprise the same material. Therefore, the boundary between the first adhesive layer 31 and the second adhesive layer 32 may not be distinguished.

[0060] In addition, Figure 2A as well as Figures 2B to 4 The diagram shows that the adhesive layer 30 includes a first adhesive layer 31 and a second adhesive layer 32, but in an embodiment, the adhesive layer 30 may be a single layer (e.g., a single layer) formed by a single process.

[0061] In this manner, during the process of providing (e.g., manufacturing) the display device, an adhesive layer 30 is formed to attach the cover glass CG to (e.g., as...) Figure 1(in the middle) having a polarization layer 20 or (as) Figure 4 The stacked structure of the display panel DP (without polarization layer 20) is constructed, and an adhesive layer 30 is formed by coating and curing optically clear resin (OCR). However, optically clear resin (OCR) has fluidity, and therefore controlling its fluidity during coating is difficult. Consequently, during the OCR coating process used to form the adhesive layer 30, resin may overflow from the edges of the layers inside the stacked structure coated with the OCR material. When the coated resin overflows from the edges, it can be absorbed into other layers forming the stacked structure of the display device, or problems such as separation of interfaces between layers in contact with each other may occur, which could affect the reliability of the display device.

[0062] However, the display device according to the embodiment solves problems such as overflow or vapor generation of the coated OCR by forming grooves in the cover glass CG and / or the light-blocking member BM to guide or restrict the movement of the material used to form the OCR along the layer coated with the material. Detailed embodiments will be described below with reference to the accompanying drawings.

[0063] Figure 5 The planar shapes of the display panel DP and the cover glass CG of a display device according to an embodiment are schematically shown. (Reference) Figure 5 The cover glass CG includes a groove 10 disposed along the edge of the display panel DP and extending around the display panel DP, such as along the periphery or outer edge of the display panel DP. The groove 10 may be a recess defined to extend into the thickness of the cover glass CG and open along the thickness direction to face the display panel DP and its various components or layers. A portion of the cover glass CG may define a recess. In an embodiment, the groove 10 is recessed into a portion of the thickness of the cover glass CG.

[0064] In one embodiment, the slot 10 can be disposed inside the outer edge of the display panel DP along the edge of the display panel DP, such that the outer edge surrounds the slot 10. In another embodiment, wherein... Figure 5 The dashed line in the diagram represents the boundary of the display area of ​​the display panel DP displaying the image, and the slot 10 can be disposed along this boundary to surround the display area of ​​the display panel DP. Here, the boundary can be the place where the display area and the inner end of the light-blocking member BM (e.g., corresponding to the non-display area of ​​the display panel DP) meet each other. That is, the inner end of the light-blocking member BM can define the boundary between the display area and the non-display area within the display device, but is not limited thereto.

[0065] The slot 10 may have a closed-loop shape in a planar view to surround a planar area of ​​the display panel DP or the polarizing layer 20 (similar to the display area of ​​the display panel DP). The slot 10 may be continuous along a corresponding side or outer edge of the display device.

[0066] Figure 6 It was taken from line VI-VI'. Figure 5 A sectional view. (Reference) Figure 6 The polarizing layer 20 and the adhesive layer 30 are disposed on the display panel DP, and the cover glass CG can be disposed on the adhesive layer 30. For example... Figure 6 As shown, the light-blocking member BM, which serves as a light-blocking layer, can be located at the edge of the cover glass CG. (Reference) Figure 5 and Figure 6 The light-blocking member BM can extend along the edge of the cover glass CG and correspond to the extension of the groove 10. In an embodiment, the light-blocking layer can extend from the inside of the groove 10 to the outer edge of the cover glass CG.

[0067] A groove 10 is provided at the edge of the cover glass CG, and a portion of the adhesive layer 30 can extend into the groove 10 to be disposed within the groove 10. In an embodiment, the material of the adhesive layer 30 can completely fill the groove 10, but is not limited thereto. (See reference...) Figure 6 For example, the display panel DP includes a side surface extending along the outer edge of the cover glass CG (e.g., Figure 6 The polarization layer 20 and / or the end-side surface of the display panel DP shown. Along the direction of the display device (e.g., Figure 6 The horizontal line in the middle or along Figure 5 On the plane shown, the end of the adhesive layer 30 closest to the outer edge of the cover glass CG is adjacent to the side surface of the display panel DP. That is, the end of the adhesive layer 30 is not disposed on the side surface. When “adjacent”, the end of the adhesive layer 30 can be non-overlapping, such as being spaced apart from the side surface.

[0068] A light-blocking member BM can be disposed within the groove 10. The light-blocking member BM can have a cross-sectional profile corresponding to the cross-sectional profile of the groove 10. The light-blocking member BM can form an opening groove facing the display panel DP and its various components or layers. The opening groove may include, but is not limited to, a recessed portion of the light-blocking member BM corresponding to the thickness of the cover glass CG. That is, the opening of the recessed portion of the light-blocking member BM can be coplanar with the opening of the groove 10 in the cover glass CG. Therefore, due to the light-blocking properties of the light-blocking member BM, even if the adhesive layer 30 is filled within the groove 10, the adhesive layer 30 can be invisible from the outside.

[0069] like Figure 5 and Figure 6As shown, the groove 10 can be configured to extend into the thickness of the cover glass CG and longitudinally along the edge of the display panel DP, and the adhesive layer 30 can be disposed within the groove 10. In other words, during the process of forming the adhesive layer 30 using OCR, when resin flows from the inner region of the display panel DP to its outer edge, the resin can prevent it from flowing beyond the outer edge of the display panel DP and instead collect within the groove 10. That is, the groove 10 acts like a dam and can prevent resin from overflowing from the display panel DP and / or the polarizing layer 20. Figure 6 As shown, the light-blocking member BM is formed in the groove 10, and therefore the groove 10 can be invisible from the outside.

[0070] Figure 7 and Figure 8 An embodiment excluding slot 10 is shown.

[0071] like Figure 7 As shown, when the groove 10 is not present in the layer of the stacked structure facing the display device, resin may overflow and be absorbed into other structures or layers such as the display panel DP and / or the polarizing layer 20. This can degrade the reliability of the display device. That is, as... Figure 7 As shown, when the adhesive layer 30 is formed on an area other than the area between the polarizing layer 20 and the cover glass CG or the blank space, such as the top and side surfaces of the display panel DP or the side surface of the polarizing layer 20, the reliability of the display device may be reduced.

[0072] In addition, such as Figure 8 As shown, when the resin flows without being restricted by the groove 10, it may affect the reliability of the tape 50 that may subsequently adhere. That is, as Figure 8 As shown, when resin flows through the target area of ​​the stacked structure, an adhesive layer 30 can be formed on the light-blocking member BM at a location between the light-blocking member BM and another layer or component. In this case, the adhesion of the tape 50, which is another layer disposed on the light-blocking member BM, may be reduced.

[0073] However, the display device according to this embodiment solves this problem by including a groove 10 provided at or near the outer edge of the cover glass CG and allowing resin to be positioned within the groove 10.

[0074] previously, Figure 5 and Figure 6 The diagram shows that the slots 10 are formed in a single row in the direction from the outer edge of the display panel DP to the cover glass CG, but the number of slots 10 can vary.

[0075] Figure 9 The display device according to the embodiment is shown with Figure 6 A similar cross-section as shown in the image. (Reference) Figure 9 Except that the slot 10 includes a first slot 11 as a first sub-slot, a second slot 12 as a second sub-slot, and a third slot 13 as a third sub-slot (which are arranged along the cover glass CG in the direction from the display panel DP to the outer edge of the cover glass CG), the display device according to this embodiment and Figure 6 The display device is the same as that in the example. Detailed descriptions of the same components are omitted. When multiple slots 10 are included in this manner, even with a relatively large amount of resin overflow in the direction toward the outer edge of the cover glass CG, it can be stably controlled.

[0076] The previously described display device includes a display panel DP, a polarizing layer 20, an adhesive layer 30, and a cover glass CG (or, for example, based on...). Figure 4 The display device according to other embodiments may include a reflection reduction layer 400 (e.g., an anti-reflection layer) disposed between the polarizing layer 20 and the adhesive layer 30.

[0077] Figure 10 The display device according to the embodiment is shown with Figure 6 A similar cross-section as shown in the image. (Reference) Figure 10 In addition to including a reflection reduction layer 400 between the polarizing layer 20 and the adhesive layer 30, the display device according to this embodiment and Figure 6 The display device is the same. Detailed descriptions of the identical components are omitted. Reference Figure 10 The reflection reduction layer 400 can reduce the reflection of external light. This can be applied to vehicle displays, etc.

[0078] Furthermore, in the previously described embodiments, the cross-sectional shape of the groove 10 is shown as triangular, but the cross-sectional shape of the groove 10 is not limited to this.

[0079] Figure 11 and Figure 12 The display device according to the embodiment is shown with Figure 6 A similar cross-section as shown in the image. Figure 11 As shown, the cross-sectional shape of the groove 10 can be circular or semi-circular, and as... Figure 12 As shown, the cross-sectional shape of the groove 10 can be quadrilateral. Grooves 10 with these various shapes can be formed by machining a cover glass CG to define a groove 10 having a cross-sectional shape therein. (Reference) Figure 6 For example, this cross-sectional shape can extend along the length of the corresponding side of the cover glass CG to define a groove 10 extending longitudinally along the corresponding outer edge of the cover glass CG.

[0080] The above description describes a configuration for controlling resin flow by forming a groove 10 in the cover glass CG, but in an embodiment, the groove 10 may be formed in the light-blocking member BM.

[0081] Figure 13 The display device according to the embodiment is shown with Figure 6 A similar cross-section as shown in the image. (Reference) Figure 13 In the display device according to this embodiment, the cover glass CG may have a flat lower surface closest to the display panel DP. Here, the light-blocking member BM disposed at the edge of the cover glass CG may include or define a groove 40. Figure 13 As shown, the adhesive layer 30 can be disposed within the groove 40. The material of the adhesive layer 30 can completely fill the groove 40, but is not limited to this, wherein the opening of the groove 40 is coplanar with the lower surface of the light-blocking member BM. That is, the flow of resin can be controlled by the groove 40 disposed in the light-blocking member BM. The groove 40 disposed in the light-blocking member BM can act as a dam to prevent resin from flowing to the outer edge of the display device. Other components and... Figure 6 The components are the same, therefore no further description will be provided. Figure 13 In this design, the cross-sectional shape of the groove 40 is shown as circular (e.g., curved like a semicircle), but is not limited to this. The cross-sectional shape and number of the groove 40 can vary.

[0082] In one embodiment, the groove 40 is partially recessed into the thickness of the light-blocking layer (e.g., the light-blocking member BM) so as not to penetrate the thickness of the light-blocking member BM. That is, even in embodiments in which the groove 40 is formed in the light-blocking member BM, the number and shape of the groove 40 can vary. Figures 14 to 17 The following are illustrations of display devices according to various embodiments. Figure 13 A similar cross-section as shown in the diagram. In various embodiments, the shape of the groove 40 can be as shown in the diagram. Figure 14 The quadrilateral shown, or it could be like... Figure 15 The triangle shown. Furthermore, as... Figure 16 As shown, the slot 40 can be configured in multiple ways, including a first slot 41 as a first sub-slot and a second slot 42 as a second sub-slot, wherein the second sub-slot is closer to the outer edge of the cover glass CG than the first sub-slot. Furthermore, as... Figure 17 As shown, it may also include a reflection reduction layer 400 disposed between the polarizing layer 20 and the adhesive layer 30.

[0083] exist Figure 5 , Figure 6 as well as Figures 9 to 12 In one embodiment, the groove 10 is disposed within the cover glass CG, and a separate light-blocking member BM is disposed within the groove 10 to prevent the groove 10 from being visible. However, in Figures 13 to 17In one embodiment, the slot 40 is visible from the outside because the slot 40 is formed in the light-blocking member BM.

[0084] As described above, the display device according to this embodiment includes a recess configured to extend along (or parallel to) the edge of the cover glass CG, or configured to extend along (or parallel to) the edge of the light-blocking member BM. During the formation of the adhesive layer 30 containing the OCR, the recess can prevent flowable materials such as resin from overflowing from or near the outer edge of the display device, and can improve the reliability of the display device.

[0085] Although the present invention has been described in conjunction with embodiments currently considered to be practical implementations, it will be understood that the present invention is not limited to the disclosed embodiments. Rather, the present invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
