The protector unit 10 attached to at least one of them, and the adhesive composition having fluidity are spread between the lower surface of the protector unit 10 and the display area of the smart device (S) and then cured to form and protect An adhesive layer 20 for attaching the lower surface of the tab 10 to at least one of a flat display area and a curved display area, and a protector unit 10 and a smart device (S) provided at the edge of the protector unit 10 A gap forming unit 30 for forming a gap between the display areas of the , and a base layer 40 disposed between the protector unit 10 and the display area of the smart device (S).

The protector unit 10 is applied to a smart device (S) having a display unit having a curved display area as well as a flat display area, for example, a smartphone to protect the entire display area of the smart device (S). In addition, the damaged or damaged area of the display unit may be restored. This embodiment can also be applied to the smart device S having only a flat display area without the aforementioned curved display area.

The curved area part 12 of the protector part 10 may extend to have a constant width from each of the long sides of the planar area part 11 , and may have a downwardly convex curved surface with reference to FIG. 1 .

In this embodiment, the curved area part 12 may have a curvature that continuously changes so as not to form a discontinuous surface at the boundary with the flat area part 11, and is located on both sides of the flat display area of the display area of the smart device S, respectively. They are respectively disposed on the formed curved display areas to protect them.

The adhesive layer 20, as shown in FIG. 2, may be provided between the base layer 40 and the display area of the smart device (S), and as shown in (a) of FIG. It may be provided between the tab part 10 and the display area of the smart device S, or it may be provided between the protector part 10 and the base layer 40 as shown in FIG. 4(c). and may be provided between a pair of base layers 40 as shown in FIG. 4( d ).

In this embodiment, the adhesive layer 20 is a protector unit 10 or a base layer 40 disposed on the adhesive layer 20, an adhesive object disposed under the adhesive layer 20, for example, a smart device. It can be attached wholly or partially to the display area of (S).

In this embodiment, the adhesive layer 20 is not only between the flat display area of the smart device S and the flat area 11 of the protector 10 and 10, but also the curved display area of the smart device S and the pro It may also be positioned between the curved area parts 12 of the tector part 10 . In this embodiment, that the protector part 10 is attached to the display area of the smart device (S) or the smart device (S) by the adhesive layer 20 means that the protector part 10 is the smart device (S). It can be defined as including a case in which the protector unit 10 is attached to another film or coating film (not shown) attached to the display area of the smart device (S) as well as the case where it is directly attached to the display area of .

In this embodiment, when the adhesive layer 20 attaches only a partial region of the lower surface of the protector unit 10 to the display area of the smart device (S), the display of the protector unit (10) and the smart device (S) Among the regions between the regions, an air layer is formed in the region where the adhesive layer 20 is not formed, thereby lowering the sensitivity of the smart device (S) to the user's touch, and due to the difference in optical characteristics between the air layer and the adhesive layer 20, From the perspective of a user viewing the smart device S through the tector unit 10 , there may be a problem in that the display characteristics of the smart device S are deteriorated. However, in this embodiment, since the entire area of the lower surface of the protector unit 10 can be attached to the display area of the smart device S using the adhesive layer 20, the above-described decrease in touch sensitivity or decrease in display characteristics can prevent

In this embodiment, the adhesive layer 20 is protected by applying the adhesive composition having fluidity on the display area of the smart device (S) and then loading the protector unit 10 on the display area of the smart device (S). It may be formed by spreading the adhesive composition over the entire area of the lower surface of the protector part 10 by the weight of the tab part 10 and then curing the adhesive composition. For example, the pressure-sensitive adhesive composition may be cured by photopolymerization or thermal polymerization.

In general, due to limitations in the manufacturing process, the radius of curvature of the curved area of the protector unit 10 and the radius of curvature of the curved display area of the smart device (S) have different values within the allowable margin for each individual product, so that the smart device (S) ) The radius of curvature of the curved display area and the radius of curvature of the curved area of the protector unit 10 applied thereto are different from each other. As a result, when attaching the protector unit 10 to the smart device (S) using a known adhesive member such as an adhesive film without fluidity, the adhesive member covers the entire area of the lower surface of the protector unit 10 to the smart device. Since it cannot be attached to the device (S), an unintended air layer is formed between the protector unit (10) and the display area of the smart device (S).

However, in this embodiment, as described above, the adhesive composition having fluidity is spread between the protector unit 10 and the smart device (S) and then cured to attach the protector unit (10) to the smart device (S). Therefore, the entire area of the lower surface of the protector unit 10 can be attached to the smart device (S), and as a result, it is possible to prevent the deterioration of the sensitivity and display characteristics to the user's touch described above. That is, since the thickness of the adhesive layer 20 formed as described above can be changed to compensate for the difference between the protector unit 10 and the smart device (S) even if the interval is not constant, the protector unit ( 10) The entire area of the lower surface can be attached to the smart device (S).

In one embodiment, the pressure-sensitive adhesive composition may have a viscosity of about 1 to 500 cps. When the viscosity of the adhesive composition is less than 1 cps, the surface tension of the adhesive composition is too weak, so that the adhesive composition spreads to the outside of the protector part 10 beyond the area between the protector part 10 and the smart device (S). When the viscosity of the adhesive composition exceeds 500 cps, the fluidity of the adhesive composition is low, so that only the weight of the protector part 10 does not spread to the entire area of the lower surface of the protector part 10. In one embodiment, the viscosity of the pressure-sensitive adhesive composition preferably has a viscosity of about 10 to 250 cps.

Meanwhile, the present embodiment may further include a water/oil repellent pattern (not shown) formed with a predetermined width along the edge of the protector unit 10 separately from the aforementioned gap forming unit 30 .

In this embodiment, the water/oil repellency pattern may be formed of a material having both water repellency and oil repellency. If the material has water repellency and oil repellency at the same time, it may be used without limitation as the material of the water/oil repellency pattern, and is not particularly limited. For example, the water/oil repellency pattern is PTFE (polytetrafluoroethylene), PFA (Perfluoroalkoxy), FEP (Fluorinated ethylene propylene), ETFE (Ethylene + Tetrafluoroethylene), ETEE (Tetrafluoroethylene ethylene copolymer), PCTFE (Trichlorotrifluoroethylene), ECTFE (Ethylene- Fluorine-based polymers such as Chlorotrifluoroethylene), PVDF (Polyvinylidene fluoride), PVF (Polyviny fluoride), or PI (Polyimide), PEEK (Polyether etherketone), PPS (Polyhenylene sulfide), PA (Polyamide), POM (Polyacetal), PAI (Polyamide) imide), polyether sulfone (PES), polyether imide (PEI), polycabonate (PC), and polypenylene ether (PPE).
