[0058] In the following description, for the purpose of explanation, many specific details are set forth to provide a thorough understanding of various exemplary embodiments or implementations of the present invention. As used herein, "implementation" and "implementation" are interchangeable words, and they are non-limiting examples of devices or methods using one or more of the inventive concepts disclosed herein. However, it is apparent that various exemplary embodiments can be practiced without specific details or in the case of one or more equivalent arrangements. In other examples, known structures and devices are shown in block diagram form to avoid unnecessary confusion of various exemplary embodiments. In addition, various exemplary embodiments may be different, but need not be exclusive. For example, without departing from the inventive concept, the specific shape, configuration and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0059] Unless otherwise specified, the exemplary embodiments shown will be understood as providing exemplary features of varying details of some ways in which the inventive concept can 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 various embodiments may be combined, separated, interchanged and / or rearranged in other ways without departing from the inventive concept.

[0060] The use of cross hatching and / or shading in the drawings is generally provided to clarify the boundaries between adjacent elements. As such, unless otherwise specified, the presence or absence of cross hatching or shading will not convey or indicate any preference or requirement for a particular material, material performance, size, ratio, commonality between the elements shown, and / or any other characteristics, attributes, performances, etc. of the elements. In addition, in the drawings, the size and relative size of the elements may be exaggerated for the purpose of clarity and / or description. When the exemplary embodiments may be implemented differently, the specific process sequence may be performed differently from the described sequence. For example, two processes described in succession may be performed substantially simultaneously or in an order opposite to the described sequence. In addition, similar reference numerals represent similar elements.

[0061] When an element or layer is referred to as being "on", "connected to" or "coupled to" another element or layer, the element or layer may be directly on, connected to or coupled to another 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 coupled to" another element or layer, there are no intermediate elements or layers. For this reason, the term "connected" may indicate a physical, electrical and / or fluid connection with or without an intermediate element. In addition, the D1-axis, D2-axis and D3-axis are not limited to the three axes of a rectangular coordinate system (such as an x-axis, a y-axis and a z-axis), and may be interpreted in a broader sense. For example, the D1-axis, D2-axis and D3-axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other. For the purpose 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 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.

[0062] Although the terms "first", "second", etc. may be used herein to describe various types of elements, these components should not be limited by these terms. These terms are used to distinguish one element from another element. Therefore, without departing from the teachings of the present disclosure, the first element discussed below may be referred to as the second element.

[0063] Spatially relative terms such as "below," "below," "below," "above," "on," "above," "higher," "side" (e.g., as in "sidewall") and the like may be used herein for descriptive purposes to describe the relationship of one element to another element as shown in the figures. In addition to the orientations depicted in the figures, spatially relative terms are also intended to cover different orientations of the device in use, operation and / or manufacture. For example, if the device in the figure is flipped, an element described as being "below" or "below" other elements or features will subsequently be oriented to be "above" the other elements or features. Thus, the exemplary term "below" may include both orientations of above and below. In addition, the device may be oriented in other ways (e.g., rotated 90 degrees or at other orientations), and, as such, the spatially relative descriptors used herein should be interpreted accordingly.

[0064] The professional terms used herein are for the purpose of describing specific embodiments and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one" and "the" as used herein are also intended to include plural forms. In addition, the term "including", when used in this specification, indicates the existence of stated features, integers, steps, operations, elements, parts and / or its clusters, but does not exclude the existence or addition of one or more other features, integers, steps, operations, elements, parts and / or its clusters. It is also noted that, as used herein, the terms "substantially", "about" and other similar terms are used as approximate terms rather than terms of degree, and, as such, are utilized to consider the inherent deviations of measured values, calculated values ​​and / or provided values ​​that will be appreciated by those of ordinary skill in the art.

[0065] Various exemplary embodiments are described herein with reference to cross-sectional illustrations and / or exploded illustrations that are schematic illustrations of idealized exemplary embodiments and / or intermediate structures. As such, variations in the shapes of the illustrations as a result of, for example, manufacturing techniques and / or tolerances are to be expected. Thus, the exemplary embodiments disclosed herein should not necessarily be construed as limited to the shapes of the particular illustrated regions, but rather include deviations in shape that result from, for example, manufacturing. In this manner, the regions illustrated 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, as such, are not necessarily intended to be limiting.

[0066] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as those commonly understood by those of ordinary skill in the art to which the present disclosure belongs. Unless explicitly defined as such herein, terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology and should not be interpreted in an idealized or overly formal manner.

[0090] For example, the first sub-shaft AX1 and the second sub-shaft AX2 may be respectively coupled to a plurality of gears GE1 and GE2, and the plurality of gears GE1 and GE2 rotate while meshing with each other. When the first sub-shaft AX1 and the second sub-shaft AX2 rotate, the plurality of gears GE1 and GE2 respectively coupled to the first sub-shaft AX1 and the second sub-shaft AX2 may rotate while meshing with each other.

Fig. 9 1 is a cross-sectional view showing the first unfolded support portion SP1, the first folding support portion SP1-F, the second unfolded support portion SP2, and the second hinge portion HIG2-a and the first hinge portion HIG1 in a state where the display device is unfolded. Fig. 9 It is shown that the first unfolded supporting portion SP1, the first folding supporting portion SP1-F, and the second unfolded supporting portion SP2 are unfolded so as to be arranged parallel to each other, and Fig.10 It is shown that the first non-folded supporting portion SP1 and the second non-folded supporting portion SP2 are folded so as to overlap each other. Fig.11 is shown with Fig. 9 The area AA-1 corresponds to a cross-sectional view of the portion, and Fig.12 is shown with Fig.10 The section view of the portion corresponding to area AA-2.

[0100] Fig.13 and Fig.14 1 and 2 are cross-sectional views each showing a first non-folding supporting portion SP1, a first folding supporting portion SP1-F, and a second non-folding supporting portion SP2, and a second hinge portion HIG2-a1 and a first hinge portion HIG1 according to an exemplary embodiment.

Fig.15 is shown with Fig.13 The section view of the portion corresponding to area AA-3, and Fig.16 is shown with Fig.14 A cross-sectional view of a portion corresponding to area AA-4.

[0101] Fig.17 and Fig.18 1 and 2 are cross-sectional views each showing a first non-folding supporting portion SP1, a first folding supporting portion SP1-F, and a second non-folding supporting portion SP2, and a second hinge portion HIG2-b and a first hinge portion HIG1 according to an exemplary embodiment. Fig.17 It is shown that the first unfolded supporting portion SP1, the first folding supporting portion SP1-F, and the second unfolded supporting portion SP2 are unfolded so as to be arranged parallel to each other, and Fig.18 It is shown that the first non-folded supporting portion SP1 and the second non-folded supporting portion SP2 are folded so as to overlap each other. Fig.19 is shown with Fig.18 Area BB corresponds to a cross-sectional view of the portion.

[0102] Reference Fig.11 and Fig.16 , the plurality of first adjustment parts OP-a and OP-aa1 may be elastic bodies. When the plurality of first adjustment parts OP-a and OP-aa1 are elastic bodies, the plurality of first adjustment parts OP-a and OP-aa1 may be substantially the same as the plurality of first adjustment parts OP-a and OP-a1 described above, and therefore a repeated description thereof will be omitted. Meanwhile, as the first sub-axis AX1 and the second sub-axis AX2 rotate, the state of the first adjustment part OP-a, which may be in the form of a spring or the like, may change.

[0103] Hereinafter, the first mode may indicate that the first non-folding support portion SP1 and the second non-folding support portion SP2 are folded to overlap each other, and the second mode may indicate that the first non-folding support portion SP1, the first folding support portion SP1-F and the second non-folding support portion SP2 are unfolded to be arranged in parallel with each other. As such, the states of the plurality of first adjustment portions OP-a and OP-a1 may be different in the first mode and the second mode.

[0104] Reference Fig.11 and Fig.12 , the length AL2 of the first adjustment portion OP-aa in the first mode may be different from the length AL1 of the first adjustment portion OP-a in the second mode. More specifically, when the first non-folding support portion SP1 and the second non-folding support portion SP2 are folded to overlap each other in the first mode, the first sub-axis AX1 and the second sub-axis AX2 may rotate, and the length of the first adjustment portion OP-aa connected to the first sub-axis AX1 and the second sub-axis AX2 may be extended.

[0105] Reference Figures 13 to 16 The first adjustment portion OP-a1 may be arranged below the center portion CTR. The first adjustment portion OP-a1 may be connected between the first folding support portion SP1-F and the first non-folding support portion SP1, and may be positioned below the center portion CTR of the third sub-hinge portion HIG2-3S or the fourth sub-hinge portion HIG2-4S.

[0106] For example, the first adjustment portion OP-a1 may be an elastic body, such as a spring or a rubber band. Fig.15 and Fig.16 , the length AL4 of the first adjustment portion OP-aa1 in the first mode may be different from the length AL3 of the first adjustment portion OP-a1 in the second mode. More specifically, when the first non-folding support portion SP1 and the second non-folding support portion SP2 are folded to overlap each other in the first mode, the length AL4 of the first adjustment portion OP-aa1 may be extended to a greater extent than the length AL3 of the first adjustment portion OP-a1 in the second mode.

[0107] In some exemplary embodiments, when the adjustment portion is a rubber band, the length of the rubber band in the first mode and the length of the rubber band in the second mode may be different. The rubber band may be included in the central portion of the hinge to connect the sub-axis, or may be arranged on the lower portion of the hinge. Similar to the case of the above-mentioned spring, the length of the rubber band in the first mode may be extended to a greater extent than the length of the rubber band in the second mode. However, the inventive concept is not limited thereto.

[0111] Reference Figures 17 to 19, the first sub-electromagnet OP-b1 and the second sub-electromagnet OP-b2 may be spaced apart in the first mode and coupled to each other in the second mode. More specifically, when the first non-folding support portion SP1 and the second non-folding support portion SP2 are folded to overlap in the first mode, the first sub-electromagnet OP-b1 and the second sub-electromagnet OP-b2 may be spaced apart from each other. In addition, when the first non-folding support portion SP1 and the second non-folding support portion SP2 are unfolded in the second mode to be arranged in parallel, the first sub-electromagnet OP-b1 and the second sub-electromagnet OP-b2 may be coupled.

The first adjustment portion and the second adjustment portion may be positioned in the inner portion CTR-I of the central portion CTR of the plurality of hinge portions HIG2-a and HIG4-a (see Figure 8 ).

[0120] According to an exemplary embodiment, when the plurality of support portions SP1, SP1-F, SP2, SP2-F, and SP3 are folded to overlap each other, the first state of the first adjustment portion and the second state of the second adjustment portion may be different from each other. The first state of the first adjustment portion may be different from the first adjustment portion OP-a (see FIG. Fig.11 ) is substantially the same, and the second state of the second adjustment portion can be the same as the first adjustment portion OP-aa (see Fig.12 ) is substantially the same.

Fig.12 The first adjustment portion OP-aa) is in a second state in which the length is extended.

[0121] exist Fig.23, the first adjustment portion OP-a1 is shown as being arranged below the second hinge portion HIG2-a1, and the second adjustment portion OP-aa1 is shown as being arranged below the fourth hinge portion HIG4-a1. The first adjustment portion OP-a1 may indicate a first state, and the second adjustment portion OP-aa1 may indicate a second state. The length OP-4a of the second adjustment portion OP-aa1 in the second state may be extended to a greater extent than the length OP-3a of the first adjustment portion OP-a1 in the first state. The length OP-3a of the first adjustment portion OP-a1 arranged below the unfolded second hinge portion HIG2-a1 and the length OP-4a of the second adjustment portion OP-aa1 arranged below the fourth hinge portion HIG4-a1 may be different from each other.

A hinge portion HIG1, HIG2-a, HIG2-a1, HIG2-b, HIG3, HIG4-a, HIG4-a1, or HIG4-b coupled to one side of the folding area FA1 or FA2 may be folded or unfolded according to the order in which a plurality of non-folding areas NFA1, NFA2, and NFA3 overlap. In addition, the state of the adjustment portion in the folded hinge portion and the state of the adjustment portion in the unfolded hinge portion may be different from each other. In the folded hinge portion, the adjustment portion may be deformed so that the folding region is easily folded, and in the unfolded hinge portion, the adjustment portion may be adjusted so that the folding region is not unfolded.

[0124] exist Figure 22 to Figure 24 , the second non-folding support portion SP2, the first non-folding support portion SP1 and the third non-folding support portion SP3 are shown to overlap and fold in this order. However, the inventive concept is not limited to this.
