Title: Cover window and manufacturing method of the same

Description:
This application is a divisional of U.S. patent application Ser. No. 14/047,201, filed on Oct. 7, 2013, which claims priority to Korean Patent Application No. 10-2013-0064333, filed on Jun. 4, 2013, and all the benefits accruing therefrom under 35 U.S.C. § 119, the content of which in its entirety is herein incorporated by reference. 
    
    
     BACKGROUND 
     1. Field 
     The embodiments described herein relate to a cover window and a manufacturing method of the same. 
     2. Description of the Related Art 
     Mobile-based electronic devices are increasingly being used over office based electronic devices. Examples of mobile electronic devices may include, for example, but not limited to, tablet personal computers (“PCs”) that have become widely used in recent years over using laptop PCs. Further examples also include small electronic devices, such as mobile phones and the like. 
     Such mobile electronic devices typically include a display unit to provide visual information to a user. Such visual information, including images or videos often support various functions of the mobile electronic device to which the display unit is a part thereof. Recently, as other components for driving a display unit have become miniaturized, the display unit is the primary interface between the user and the mobile electronic device. Furthermore, a display unit which is bendable from a flat state at a predetermined angle is being developed. Thus, the display unit of a mobile electronic device as described above may be flexible. 
     A cover window may be attached to an outer surface of the display unit to protect an exterior of the display unit. The cover window may be formed of various materials. For example, the cover window may be formed of a glass material or a synthetic resin. The cover window may also be injection-molded using a synthetic resin material; however, a disadvantage of this manufacturing method is that the cover window may become delaminated after manufacturing, thereby causing defects thereof. 
     SUMMARY 
     Exemplary embodiments of the exemplary embodiment provide a cover window and a manufacturing method of the same. The manufacturing method is capable of reducing the occurrence of delamination of each layer comprising the cover window. 
     According to an exemplary embodiment of the invention, a cover window is provided which includes: a film layer; and a resin layer disposed on the film layer which surrounds an edge of the film layer. 
     At least one portion of the film layer and at least one portion of the resin layer may be bent. 
     The film layer may have an area that is less than the area of the resin layer. 
     The film layer may be formed of the same material as the resin layer. 
     The film layer may further include a film body and a shielding layer disposed on at least one portion of the film body. 
     The resin layer may further include a body part and a supporting part extending therefrom to surround the edge of the film layer. 
     The cover window may further include a protection layer disposed on at least one portion of the film layer to face the resin layer which surrounds the edge of the film layer. 
     The resin layer may surround an edge of the protection layer and the edge of the film layer. 
     The protection layer may be disposed on at least one portion of the resin layer surrounding the edge of the film layer and at least one portion of the film layer. 
     The cover window may further include a binder layer disposed between the film layer and the resin layer. 
     At least two of the following layers may be formed of the same material: the film layer, the resin layer, or the binder layer 
     The resin may be injection-molded on the film layer through an in-mold-labeling (“IML”) process to manufacture the resin layer. 
     According to another aspect of the exemplary embodiment, a method of manufacturing a cover window is provided. The method includes bending at least one portion of the film layer, and injection-molding a resin on an outer surface of the film layer to form a resin layer surrounding an edge of the film layer. 
     The resin may be injection-molded through an IML process to form the resin layer. 
     The method may further include forming a protection layer on the film layer before bending at least one portion of the film layer to injection-mold a resin on an outer surface of the film layer. 
     The injection-molding of the resin may include injection-molding the resin to surround the edge of the film layer and an edge of the protection layer. 
     The method may further include: forming a protection layer on at least one portion of the film layer and at least one portion of the resin layer after the injection-molding of the resin on the film layer to form the resin layer. 
     The method may further include: forming a binder layer on the film layer before the bending of the at least one portion of the film layer. 
     The resin may be injected from the edge of the film layer toward a central portion of the film layer. 
     The edge of the film layer surrounded by the resin layer includes two opposing ends defining two opposing terminal ends of the thin film layer.

     DETAILED DESCRIPTION 
     The present invention will be clarified through the following embodiments described with reference to the accompanying drawings. 
     The exemplary embodiments of the invention may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concept of the invention to those skilled in the art, and the exemplary embodiments of the invention will only be defined by the appended claims.
 
It will be understood that when an element or layer is referred to as being “on” or “connected to” another element or layer, the element or layer can be directly on or connected to another element or layer or intervening elements or layers. In contrast, when an element is referred to as being “directly on” or “directly connected to” another element or layer, there are no intervening elements or layers present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
 
It will be understood that, although the terms first, second, third, etc., can be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the exemplary embodiments of the invention.
 
Spatially relative terms, such as “below,” “lower,” “upper” and the like, can be used herein for ease of description to describe one element or feature&#39;s relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “lower” relative to other elements or features would then be oriented “above” relative to the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
 
As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
 
Embodiments of the invention are described herein with reference to cross-section illustrations that are schematic illustrations of idealized embodiments (and intermediate structures) of the invention. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments of the invention should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing.
 
For example, an implanted region illustrated as a rectangle will, typically, have rounded or curved features and/or a gradient of implant concentration at its edges rather than a binary change from implanted to non-implanted region. Likewise, a buried region formed by implantation can result in some implantation in the region between the buried region and the surface through which the implantation takes place. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to limit the scope of the invention.
 
     Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. 
     All methods described herein can be performed in a suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”), is intended merely to better illustrate the invention and does not pose a limitation on the scope of the invention unless otherwise claimed. No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the invention as used herein. 
     According to an embodiment of the present invention,  FIG. 1  is a cross-section view schematically illustrating a cover window in a width direction thereof.  FIG. 2  is a conceptual cross-section view of a mold used for manufacturing the cover window of  FIG. 1 . 
     Referring to  FIGS. 1 and 2 , a cover window  100  may include a film layer  110 . The film layer  110  may include a film body  111  and a shielding layer  112  disposed on at least one portion of the film body  111 . 
     In an embodiment, the film body  111  may have at least one bent portion. In another embodiment, the film body  111  may be bent in various shapes. For example, the film body  111  may have a curved surface with a selected radius of curvature. In another embodiment, the film body  111  may have only one bent portion. For example, the film body  111  may have a flat shape except at an edge thereof. That is, only the edge of the film body  111  may be bent. Here, both side edges of the film body  111  may be bent. Alternatively, only one side edge of the film body  111  may be bent. 
     In an embodiment, the film body  111  may have a plurality of curved surfaces having different radii of curvature. In detail, the film body  111  may have a first curved surface having a first radius of curvature, a second curved surface having a second radius of curvature, a third curved surface having a third radius of curvature, . . . and an N-th curved surface having an N-th radius of curvature (where N is a natural number). In an embodiment, the first curved surface, the second curved surface, the third curved surface, . . . and the N-th curved surface may be connected to each other. 
     In particular, the film body  111  is not limited to the above described shapes. If at least one portion of the film body  111  is bent, the film body  111  may have various shapes. 
     At least one portion of the length direction and the width direction of the film body  111  may be a curved portion. In detail, the film body  111  may be bent in the length or width direction, or alternatively, the film body  111  may be bent in both length and width directions. 
     Hereinafter, for the convenience of description, the film body  111  of which only the edge is bent will be described in detail. In addition, for convenience of description, the film body  111  of which both side edges are bent in the width direction will be described in detail. 
     The film body  111  may be bent in various directions. Referring to  FIG. 1 , the film body  111  may have an upwardly convex shape. In an alternative embodiment of  FIG. 1 , the film body  111  may have a downwardly convex shape. However, hereinafter, for convenience in description, the film body  111  having the upwardly convex shape will be described in detail. 
     In an embodiment, the film body  111  may be formed of a transparent material. For example, the film body  111  may be formed of at least one of polymethylmethacrylate (“PMMA”), polycarbonate (“PC”), polyethylene terephthalate (“PET”), polyethylene terephthalate glycol (“PETG”), and acrylonitrile butadiene styrene. The material may be provided as a resin to form the film body  111 . The film body  111  is not limited to the above-described materials and may include any injection-moldable transparent materials. 
     The shielding layer  112  may be manufactured by an inkjet printing process, a silk screen printing process, an imprinting process, or the like. Since the inkjet printing process, the silk screen printing process, the imprinting process, or the like are the same as a general process, detailed descriptions thereof will be omitted. The method of manufacturing the shielding layer  112  is not limited to the above-described methods. For example, the method may include any method of forming an opaque layer on the film body  111 . 
     As described above, the shielding layer  112  may be disposed on at least one portion of the film body  111 ; in particular, the shielding layer  112  may be disposed on the edge of the film body  111 . 
     The cover window  100  may include a resin layer  120  disposed on the film layer  110  to surround the edge of the film layer  110 . The resin layer  120  may include a body part  121  and a supporting part  122  extending from the body part  121  to surround and cover the edge of the film layer  110 . 
     The body part  121  may have the same shape as that of the film body  111 . In particular, if at least one portion of the film body  111  is bent, at least one portion of the body part  121  may also be bent along the film body  111 . The curved surface of the film body  111  may have a radius of curvature similar to that of the body part  121 . 
     The body part  121  may be formed of a transparent material. For example, the body part  121  may include at least one of PMMA, PC, PET, PETG, or acrylonitrile butadiene styrene. The material may be in resin form to mold the body part  121 . The body part  121  is not limited to the above-described materials and may include any injection-moldable transparent materials. 
     The body part  121  and the film body  111  may be formed of the same material or of different materials. In particular, if the body part  121  is formed of the same material as that of the film body  111 , the body part  121  may be firmly coupled to the film body  111  through chemical bonding. 
     The supporting part  122  may be bent. In particular, the supporting part  122  may have a groove so that the film body  111  is inserted therein. The supporting part  122  may fix the edge of the film body  111  to prevent the edge of the film body  111  from being separated from the body part  121  or the supporting part  122 . 
     The cover window  100  may include a protection layer  130  disposed on the film layer  110 . The protection layer  130  may be disposed on the film layer  110  to face the resin layer  120 . In particular, if the resin layer  120  is disposed on a first outer surface  111   a  of the film layer  110 , the protection layer  130  may be disposed on a second outer surface  111   b  of the film layer  110 , which is different from the first outer surface  111   a . Also, if the resin layer  120  is disposed in the second outer surface  111   b , the protection layer  130  may be disposed in the first outer surface  111   a . However, for convenience of description, the protection layer being disposed on the first outer surface  111   a  and the resin layer  120  being disposed on the second outer surface  111   b  will be described in detail. 
     The protection layer  130  may be formed of a material having functions including, but not limited to, external force resistance, foreign substances resistance, and static electricity resistance. Particularly, the protection layer  130  may be formed of an acrylic material. Alternatively, the protection layer  130  may be formed of a composite layer including organic and inorganic materials. The protection layer  130  may be attached to the film layer  110  in a film shape and be formed through a coating process. However, for convenience of description, the protection layer which is manufactured by the coating process will be described in detail. 
     The protection layer  130  may be disposed on one portion of the resin layer  120  surrounding the edge of the film layer  110  and one portion of the film layer  110 . In detail, the protection layer  130  may cover the body part  121  and the supporting part  122  to protect the body part  121  and a portion of the supporting part  122  against the outside. 
     In the method of manufacturing the cover window  100 , the film layer  110  may be formed of the same material as the material described above. Here, the film body  111  may be disposed on the film layer  110 , and then the shielding layer  112  may be disposed on at least one portion of the film body  111  through the inkjet printing process, the silk screening process, or the imprinting process, for example. Since the inkjet printing process, the silk screen printing process, and the imprinting process are well-known processes, detailed descriptions thereof will be omitted. 
     When the above-described process is finished, both sides of the edge of the film body  111  may be bent. Here, the film body  111  may be bent in various ways. For example, the film body  111  may be bent by being compressed or pressurized using a jig. 
     When the film body  111  is bent, the film body  111  may be disposed inside a mold (no reference character). The mold may include a first mold C 1  and a second mold C 2 . The first mold C 1  may be spaced apart from the second mold C 2  to define a space V therebetween. 
     When the film body  111  is disposed in the space V, the first outer surface  111   a  of the film body  111  may be closely attached to a surface of the first mold C 1 . Here, a first outer circumferential surface of the first outer surface  111   a  of the film body  111  may be spaced apart from the surface of the first mold C 1 . 
     As described above, after the film body  111  is disposed, the resin may be injection-molded. The resin may be injection-molded on the film layer  110  by an in-mold-labeling (“IML”) process to manufacture the resin layer  120 . In particular, the resin may be injection-molded at a temperature of about 200° C. to about 300° C. 
     The resin may include at least one of PMMA, PC, PET, PETG, and acrylonitrile butadiene styrene which are materials for forming the resin layer  120 . 
     When the resin is injected, the resin may be injected from the edge of the film body  111 . In detail, the resin may be injected from the edge in a length direction of the film body  111  and from the edge in a width direction of the film body in a central direction of the film body  111 . In particular, if the resin is injected from the edge of the film body  111  in the central direction of the film body  111 , the cover window  100  may have a pattern formed due to a flow of the resin on an edge area of the film body  111 . A pattern formed due to a flow of the resin on an edge area of the film body  111  is used to prevent deterioration of visibility or prevent defects from occurring when the display panel (not shown) is attached to the cover window  100 . 
     As described above, when the resin is injection-molded, the resin may be introduced between the first mold C 1  and the edge of the film body  111 , and between the second mold C 2  and the edge of the film body  111 . Here, the resin may flow to surround the edge of the film body  111  by at least one of the first mold C 1  and the second mold C 2 . In detail, the resin injected between the second mold C 2  and the second outer surface  111   b  of the film body may flow toward a portion of the first outer surface  111   a  of the film body  111  along a side surface of the first mold C 1 . Also, the resin may flow from a resin injection hole I defined between the first mold C 1  and the second mold C 2  into a portion of the first outer surface  111   a  of the film body  111 . 
     During the injection of the resin, if the film body  111  is formed of the same material as the resin, a portion of the material of the film body  111  may be fused according to the above described injection temperature to chemically bond the film body  111  to the resin. Thus, when the resin is cured to form the resin layer  120  after the resin is injected, the resin layer  120  may be firmly coupled to the film body  111  through the chemical bonding. 
     When the above-described process is finished, the temperature may decrease to cure the resin, thereby manufacturing the resin layer  120 . Here, the resin layer  120  may have a surface area greater than that of the film layer  110 . In detail, the resin layer  120  may have a length greater than that of the film layer  110  and a width greater than that of the film layer  110 . Thus, the supporting part  122  may fully cover the edge of the film body  111 . 
     When the above-described process is finished, the film layer  110  and the resin layer  120  may be taken out of the first mold C 1  and the second mold C 2 . Also, the protection layer  130  may be disposed on the first outer surface  111   a  of the film layer  110 . Here, the protection layer  130  may be manufactured through the coating process as described above. In detail, the protection layer  130  may be manufactured by alternately providing the acrylic material or the organic and inorganic materials through spraying or dip-coating, for example, but not limited thereto. Here, since the spraying and dip-coating are general well-known processes, detailed descriptions thereof will be omitted. 
     When the protection layer  130  is manufactured, the protection layer  130  may be disposed on the first outer surface  111   a  of the film body  111  and a portion of the supporting part  122 . Here, the protection layer  130  may protect the first outer surface  111   a  of the film body  111  and the portion of the supporting part  122  against external forces, external foreign substances, and static electricity. 
     When the resin layer  120  is manufactured, the supporting part  122  may support the edge of the film body  111  as described above. In detail, if the edge of the film body  111  is bent, the edge of the film body  111  and the resin layer  120  may be separated from each other by a restoring force of the material forming the film body  111 . Here, the supporting part  122  may be disposed to surround the edge of the film body  111  as described above, thereby preventing the edge of the film body  111  from being separated from the resin layer  120 . If the film body  111  is deformed by heat, the supporting layer  122  may support the edge of the film body  111  to prevent the film body  111  and the resin layer  120  from being separated from each other. 
     Therefore, in the cover window  100  and the method of manufacturing thereof, the film body  111  and the resin layer  120  may be firmly coupled to each other to minimize defects of the cover window  100 . Also, the method of manufacturing the cover window may be simplified to reduce working time and costs. 
       FIG. 3  is a conceptual cross-section view of a cover window in a width direction thereof, according to an alternative embodiment of the present invention. Hereinafter, like reference numerals in  FIGS. 1 and 2  denote like elements in  FIG. 3 . 
     Referring to  FIG. 3 , a cover window  200  may include a film layer  210 , a resin layer  220 , and a protection layer  230 . The film layer  210  may include a film body  211  and a shielding layer  212 . The resin layer  220  may include a body part  221  and a supporting part  222 . 
     The film layer  210 , the resin layer  220 , and the protection layer  230  are respectively similar to the film layer  110 , the resin layer  120 , and the protection layer  130  in  FIG. 1 , and thus, a detailed description thereof will be omitted here. 
     The resin layer  220  may surround an edge of the film layer  210  and an edge of the protection layer  230 . In detail, the supporting part  222  may surround the edge of the film layer  210  and the edge of the protection layer  230 . Here, the supporting layer  222  may prevent the edge of the film layer  210  from being separated from the resin layer  220 . In particular, the supporting part  222  may surround a second outer surface  211   b  of the edge of the film body  211  and a portion of the protection layer  230 . 
     A method of manufacturing the cover window  200  may be similar to the method of manufacturing the cover window  100  of  FIGS. 1 and 2  described above. 
     In detail, the film layer  210  may be manufactured and prepared. Here, the film body  211  may be manufactured through a process similar to the process described above. The shielding layer  212  may be manufactured by an inkjet printing process, a silk screen process, or an imprint process, for example. Here, since the inkjet printing process, the silk screen printing process, or the imprint process is the same as the general processes discussed above, detailed descriptions thereof will be omitted. 
     When the process is finished, the protection layer  230  may be disposed on a first outer surface  211   a  of the film body  211 . The protection layer  230  may cover an entire surface of the first outer surface  211   a  of the film body  211 . 
     When the protection layer  230  is disposed on the first outer surface  211   a  of the film body  211 , the film body  211  and the protection layer  230  may be bent. Here, the film body  211  and the protection layer  230  may be bent by using a jig as described above in  FIG. 2 . The film body  211  and the protection layer  230  may be bent so that the film body  211  and the protection layer  230  have curved surfaces having various shapes. In particular, the edge of the film body  211  may be bent. 
     When the film body  211  and the protection layer  230  are bent, the film body  211  and the protection layer  230  may be disposed between a first mold C 1  and a second mold C 2 . Here, a portion of an outer surface of the protection layer  230  may contact a surface of the first mold C 1 . 
     When the above-described process is finished, a resin may be injected between the second mold C 2  and the second outer surface  211   b  of the film body  211 . Here, as described above, the resin may be injected from the edge of the film body  211  toward a central direction of the film body  211 . 
     When the resin is injected as described above, the resin may be introduced into a space (e.g., “V” in  FIG. 2 ) between the film body  211  and the second mold C 2 . A portion of the resin may flow onto a portion of the protection layer  230  disposed on the first outer surface  211   a  of the film body  211 . As time goes by, the resin may be cured to form the resin layer  220 , thereby forming the body part  221  and the supporting part  222 . In particular, the supporting part  222  may surround the bent edge of the film body  211  as described above. The supporting part  222  may cover a surface of the protection layer  230  disposed on the edge of the film body  211  (i.e., covering terminal edges defining opposing terminal ends of the protection layer  230 ). 
     While the resin is injected, if the film body  211  is formed of the same material as the resin, a portion of the film body  211  may be fused, and thus, chemically bonded to the resin layer  220 . 
     Therefore, in the cover window  200  and the method of manufacturing thereof, the supporting part  222  surrounding the edge of the film body  211  and the portion of the supporting part  222  may be provided to prevent the bent edge of the film body  211  from being separated from the resin layer  220 . In the cover window  200  and the method of manufacturing thereof, if the film body  211  is formed of the same material as the resin, the resin layer  220  and the film body  211  may be firmly coupled to each other due to chemical bonding therebetween. 
       FIG. 4  is a conceptual cross-section view of a cover window in a width direction thereof, according to another alternative embodiment of the present invention. 
     Referring to  FIG. 4 , a cover window  300  may include a film layer  310 , a resin layer  320 , and a protection layer  330 . The film layer  310  may include a film body  311  and a shielding layer  312 . The resin layer  320  may include a body part  321  and a supporting part  322 . 
     The film layer  310 , the resin layer  320 , and the protection layer  330  are respectively similar to the film layer  110 , the resin layer  120 , and the protection layer  130  in  FIG. 1 , and thus, a detailed description thereof will be omitted. 
     The cover window  300  may include a binder layer  340  between the film layer  310  and the resin  320 . The binder layer  340  may be formed on the film body  311  through a silk screen printing process. In detail, the binder layer  340  may be disposed on a second outer surface  311   b  of the film body  311 . In particular, the binder layer  340  may have a surface area that is equal to or less than that of the film layer  310 . 
     The binder layer  340  may be formed of various materials. For example, the binder layer  340  may include at least one of PMMA, PC, PET, PETG and acrylonitrile butadiene styrene. Here, the film layer  310 , the resin layer  320 , and the binder layer  340  may be formed of materials different from each other. Alternatively, at least two of the film layer  310 , the resin layer  320 , and the binder layer  340  may be formed of the same material. However, for convenience of description, the film layer  310 , the resin layer  320 , and the binder layer  340  which are formed of the same material will be described in further detail. 
     A method of manufacturing the cover window  300  may be similar to the method of manufacturing the cover window  200  described above with respect to  FIG. 3 . 
     In further detail, after the film body  311  is manufactured, the shielding layer  312  may be disposed on at least one portion of the film body  311 . The shielding layer  312  may be manufactured by the inkjet printing process, the silk screen printing process, or the imprint process. Since the inkjet printing process, the silk screen printing process, or the imprint process are the same as the general processes described above, detailed descriptions thereof will be omitted. 
     When the process is finished, the film body  311  may be bent, and then inserted between the first mold C 1  and the second mold C 2  (shown in  FIG. 2 ). Then, the resin may be injected between the second outer surface  311   b  of the film body  311  and the second mold C 2  to dispose the resin layer  320  on the second outer surface  311   b  of the film body  311 . When the resin is injected between the molds C 1  and C 2  as described above, the resin may fuse a portion of the binder layer  340  to chemically bond to a portion of the fused binder layer  340 . 
     When the resin layer  320  is disposed as described above, the body part  321  and the supporting part  322  may be disposed as illustrated in  FIG. 4 , and the supporting part  311  may surround the edge of the film body  311 . The supporting part  322  may prevent the film body  311  from being separated from the binder layer  340  due to an insertion of the edge of the film body  311  into the supporting part  322  of the resin layer  320 . 
     When the process is finished, the protection layer  330  may be disposed on the first outer surface  311   a  of the film body  311 . The method of disposing the protection layer  330  has been described already, and thus a detailed description thereof will be omitted. 
     Therefore, in the cover window  300  and the method of manufacturing thereof, although at least one portion of the cover window  300  is bent, the supporting part  322  may fix the edge of the film body  311  to the edge of the binder layer  340  to prevent the film body  311 , the binder layer  340 , and the protection layer  330  from being separated from each other. 
       FIG. 5  is a conceptual cross-section view of a cover window in a width direction thereof, according to yet another alternative embodiment of the present invention. 
     Referring to  FIG. 5 , a cover window  400  may include a film layer  410 , a resin layer  420 , a protection layer  430 , and a binder layer  440 . The film layer  410  may include a film body  411  and a shielding layer  412 . The resin layer  420  may include a body part  421  and a supporting part  422 . 
     The film layer  410 , the resin layer  420 , the protection layer  430 , and the binder layer  440  are respectively similar to the film layer  310 , the resin layer  320 , the protection layer  330  and the binder layer  340  described in  FIG. 4 , and thus, a detailed description thereof will be omitted. 
     In the method of manufacturing the cover window  400 , the shielding layer  412  may be disposed on the film body  411  as described above, and then the protection layer  430  may be disposed on a first outer surface  411   a  of the film body  411 . A method of forming the protection layer  430  has been described above, and thus, a detailed description thereof will be omitted. 
     The binder layer  440  may be disposed on a second outer surface  411   b  of the film body  411 . A method of disposing the binder layer  440  has been described above, and thus, a detailed description thereof will be omitted. 
     When the protection layer  430  and the binder layer  440  are disposed as described above, the film body  411  may be bent. A method of bending the film body  411  has been described above in detail, and thus, a detailed description thereof will be omitted. 
     The film layer  410 , the protection layer  430 , and the binder layer  440 , which are bent, may be disposed between a first mold C 1  and a second mold C 2  as described above (and shown in  FIG. 2 ), and then the resin may be injected. Here, the resin may be injected from the edge of the film body  410  toward a central portion of the film body  410  as described above. 
     When the resin is injected between the molds C 1  and C 2  as described above, a portion of the resin may flow between the binder layer  440  and the second mold C 2  to surround the edge of the film body  411  and a portion of the protection layer  430 . Thereafter, when the resin is cured, the resin may form the resin layer  420 . 
     Here, the edge of the film body  411 , the edge of the binder layer  440 , and the edge of the protection layer  430  may be inserted into the supporting part  422  of the resin layer  420  and thus be fixed by the supporting part  422 . In particular, the supporting part  422  may prevent the bent edge of the film body  411  from returning to its original state, thus preventing the film body  411  from being separated from the binder  440 . Also, the supporting part  422  may prevent the binder layer  440  from being moved together with the film body  411 , thus preventing the binder layer  440  from being separated from the resin layer  420 . 
     Therefore, in the cover window  400  and the method of manufacturing thereof, the returning of the edge of the film body  411  to its original state may be prevented and thus, the film body  411 , the binder layer  440 , and the resin layer  420  may be prevented from being separated from each other. 
     In particular, in the cover window  400  and the method of manufacturing thereof, the delaminating of the cover window  400  in the edge area thereof may be prevented and thus a defect rate is minimized. 
     According to embodiments of the present invention, the film layer and the resin layer may be firmly coupled to each other to minimize defects of the cover window. Also, according to embodiments of the present invention, the cover window may be manufactured more simply to reduce working time and costs thereof. 
     In particular, according to embodiments of the present invention, the resin layer may be formed to surround the edge of the bent film layer to prevent the film layer and the resin layer from being separated from each other. 
     While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
