As shown in these figures, the liquid crystal screen protector 1 of the smart device according to the present embodiment includes a flat display region of the smart device S having at least one of a flat display region and a curved display region, (10) attached to at least one of the plurality of smart devices (S), and a pressure sensitive adhesive composition having fluidity spread between a lower surface of the protector part (10) and a display area of the smart device An adhesive layer 20 for attaching the lower surface of the probe 10 to at least one of a flat display area and a curved display area and an adhesive layer 20 provided at the edge of the protector part 10, And a base layer 40 disposed between the display portion of the smart device S and the protector portion 10. The gap forming portion 30 may be formed by forming a gap between the display region of the smart device S and the display region 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 smart phone to protect the entire display area of the smart device S In addition, a damaged or damaged area of the display unit can be restored. The present embodiment can be applied to a smart device S having only a flat display area without the above-described curved display area.

1, the protector 10 includes a substantially planar area 11 positioned at the center and a curved surface extending from an edge of the planar area 11, And may include one or more curved surface regions 12.

In the present embodiment, the planar region 11 and the curved region 12 may be integrally formed. In this embodiment, the curved surface region 12 may be provided at the central portion of the protector unit 10 corresponding to the central portion of the display unit of the smart device S when the center portion thereof is convex.

The planar region 11 of the protector 10 may have a rectangular shape having a pair of opposed long sides and a pair of short sides connecting the long sides, It can be placed above the area to protect it.

The curved surface area 12 of the protector 10 may extend from each of the long sides of the planar area 11 to have a constant width and may be curved downward with reference to FIG.

In the present embodiment, the curved surface area 12 may have a curvature continuously changing so as not to form a discontinuity at the boundary with the flat area 11, and may be formed on both sides of the flat display area of the display area of the smart device S And can be disposed on top of the formed curved display areas to protect them.

The adhesive layer 20 may be provided between the substrate layer 40 and the display device of the smart device S as shown in Fig. 2, and as shown in Fig. 4 (a) May be provided between the display section of the smart device 10 and the display section of the smart device S or may be provided between the protector section 10 and the base material layer 40 as shown in FIG. , Or between the pair of base layers 40 as shown in Fig. 4 (d).

The adhesive layer 20 may be formed by attaching a protective layer 10 or a substrate layer 40 disposed on the adhesive layer 20 to a sticky object disposed under the adhesive layer 20, S in the display area.

The adhesive layer 20 is formed between the flat display area of the smart device S and the flat area area 11 of the protector parts 10 and 10 as well as between the curved surface display area of the smart device S, Or between the curved surface regions 12 of the textured portion 10. The fact that the protector section 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 section 10 is attached to the smart device S, (Not shown) attached to the display area of the smart device S, as well as the case where the protector part 10 is attached to the display area of the smart device S, as well as the case where the protector part 10 is attached to another film or coating film

When the adhesive layer 20 adheres only a part of the lower surface of the protector section 10 to the display area of the smart device S in the present embodiment, the display of the protector section 10 and the display of the smart device S An air layer is formed in an area where the adhesive layer 20 is not formed to reduce the sensitivity of the smart device S to the touch of the user as well as the optical characteristics of the air layer and the adhesive layer 20, The display characteristic of the smart device S may deteriorate on the user side viewing the smart device S through the text portion 10. [ However, in this embodiment, since the entire area of the lower surface of the protector section 10 can be attached to the display area of the smart device S using the adhesive layer 20, it is possible to reduce the above- Can be prevented.

In this embodiment, the adhesive layer 20 is formed by applying a pressure-sensitive adhesive composition on the display area of the smart device S, loading the protector 10 on the upper portion of the display area of the smart device S, Spreading the adhesive composition over the entire area of the lower surface of the protector portion 10 by the weight of the adhesive portion 10, and then curing the adhesive composition. In one example, the adhesive composition can be cured by photo-polymerization or thermal polymerization.

The curvature radius of the curved surface area of the protector 10 and the radius of curvature of the curved surface display area of the smart device S are different from each other within the allowable margin for each product, The radius of curvature of the curved surface display region and the radius of curvature of the curved surface region of the protector unit 10 applied thereto are different from each other. As a result, in the case of attaching the protector section 10 to the smart device S using a known adhesive member such as an adhesive film having no fluidity, There is a problem that an unintended air layer is formed between the protector 10 and the smart device S display area because it can not be attached to the device S. However, in this embodiment, as described above, the adhesive composition having fluidity is spread between the probe unit 10 and the smart device S and then hardened to attach the probe unit 10 to the smart device S It is possible to attach the entire area of the lower surface of the protector unit 10 to the smart device S, and as a result, it is possible to prevent the deterioration of the sensitivity and display characteristics of the user touch described above. That is, since the thickness of the adhesive layer 20 formed as described above may vary to compensate for the difference between the protector part 10 and the smart device S even if the gap is not constant, 10) the entire area of the lower surface can be attached to the smart device S.

In one embodiment, the adhesive composition may have a viscosity of about 1 to 500 cps. If the viscosity of the pressure-sensitive adhesive composition is less than 1 cps, the surface tension of the pressure-sensitive adhesive composition is too weak to spread the pressure-sensitive adhesive composition beyond the area between the probe unit 10 and the smart device S, If the viscosity of the pressure-sensitive adhesive composition is more than 500 cps, the flowability of the pressure-sensitive adhesive composition is low, and the self-weight of the protector part 10 may not spread over the entire area of the lower surface of the protector part 10. In one embodiment, the viscosity of the adhesive composition preferably has a viscosity of about 10 to 250 cps.

In such a structure, the base layer 40 adhered to the protector part 10 by the adhesive can be attached to the display area of the smart device S by the above-described adhesive layer 20, It is possible to prevent the protector section 10 from being scattered when the optical disc 10 is broken.

The present embodiment may further include a water-repellent / oil-repellent pattern (not shown) formed to have a constant width along the edge of the protector section 10 separately from the gap forming section 30 described above.

In this embodiment, the water-repellent / oil-repellent pattern may be formed of a material having both water repellency and oil repellency. If the material has water repellency and oil repellency simultaneously, it can be used without limitation as the material of the water repellent / oil repellent pattern and is not particularly limited. For example, the water-repellent / oil-repellent pattern may include at least one of PTFE (Polytetrafluoroethylene), PFA (Perfluoroalkoxy), FEP (Fluorinated ethylene propylene), ETFE (Ethylene + Tetrafluoroethylene), ETFE (Tetrafluoroethylene ethylene copolymer), PCTFE (Trichlorotrifluoroethylene) Fluorinated polymers such as polyvinylidene fluoride (PVDF), polyvinyl fluoride (PVDF), polyimide, polyetheretherketone (PEEK), polyphenylene sulfide (PEK), polyamide (PA), polyacetal (POM) imide), PES (polyether sulfone), PEI (polyether imide), PC (Polycarbonate), PPE (polyphenylene ether), and the like.

In this embodiment, the adhesive composition for forming the adhesive layer 20 generally has a hydrophilic or hydrophobic property.
