[0120] The width D2, D3, D4 of each of the second light-shielding pattern CA2, the third light-shielding pattern CA3, and the fourth light-shielding pattern CA4 may be smaller than the width D1 of the first light-shielding pattern CA1. For example, the width D1 of the first light-shielding pattern CA1 may be greater than 2 mm, and the width D2, D3, D4 of each of the second light-shielding pattern CA2, the third light-shielding pattern CA3, and the fourth light-shielding pattern CA4 may be 1.5 mm.

[0124] The first adhesive layer AM1 to the sixth adhesive layer AM6 described below may be a pressure sensitive adhesive film (PSA), an optically transparent adhesive film (OCA), or an optically transparent adhesive resin (OCR). The first adhesive layer AM1 to the sixth adhesive layer AM6 contain a light-curing adhesive substance or a heat-curing adhesive substance, and the material thereof is not particularly limited. A portion of the first adhesive layer AM1 to the sixth adhesive layer AM6 may be omitted.

[0125] The end of the curved area BA of the display panel DP may be curved and disposed on the bottom of the second protective layer PF2. The end of the curved area BA may face the non-curved area NBA in the third direction DR3. The first upper surface DP-US1 of the display panel DP may be adjacent to the coating window DW than the first lower surface DP-LS1. The second upper surface DP-US2 of the display panel DP may be spaced away from the coating window DW than the second lower surface DP-LS2.

[0126] The optical unit ARU may be disposed on the upper surface DP-US of the display panel DP. The optical unit ARU may be disposed between the display panel DP and the coated window DW, overlapping the non-bending area NBA. According to the present embodiment, the optical unit ARU may not overlap the bending area BA. The optical unit ARU may be bonded to the display panel DP by the first bonding layer AM1. However, the first bonding layer AM1 may be omitted as needed.

The second protective layer PF2 may be disposed on the second lower surface DP-LS2 of the display panel DP. The second protective layer PF2 may be bonded to the support panel SSP via the sixth adhesive layer AM6. However, the sixth adhesive layer AM6 may be omitted as needed.

[0132] The first light shielding pattern CA1 may overlap the curved area BA on a plane. The first light shielding pattern CA1 may contact the side of the first protection layer PF1, the side of the second protection layer PF2, and the side of the protection panel CP. The first light shielding pattern CA1 may contact the curved area BA of the display panel DP. The first light shielding pattern CA1 may contact the curved protection layer SNL. The first light shielding pattern CA1 overlaps the curved area BA and the curved protection layer SNL, thereby preventing the curved area BA and the curved protection layer SNL from being recognized from the outside.

[0133] The first light shielding pattern CA1 may fill the space separated between the coating window DW and the display panel DP. The first light shielding pattern CA1 may fill the space separated between the display panel DP and the side of each of the first protective layer PF1, the second protective layer PF2 and the protective panel CP.

The first light shielding pattern CA1 may correspond to the first frame area BZA1. In the present utility model, the 1-1 to 1-4 light shielding patterns CA1-1 to CA1-4 are recorded with separate reference numerals and described separately, but each of the 1-1 to 1-4 light shielding patterns CA1-1 to CA1-4 may be a component including the same material formed by a single process.

[0135] The 1-1st light shielding pattern CA1-1 may be directly disposed on the optical unit ARU. The 1-1st light shielding pattern CA1-1 may overlap with the non-bending area NBA. The 1-1st light shielding pattern CA1-1 may be in the shape of a thin plate having a first thickness T1. The 1-1st light shielding pattern CA1-1 may be disposed between the optical unit ARU and the coating window DW. The coating window DW may be directly disposed on the upper surface of the 1-1st light shielding pattern CA1-1.

[0136] The 1-2nd light shielding pattern CA1-2 may extend from the 1-1st light shielding pattern CA1-1 in a direction opposite to the second direction DR2. The 1-2nd light shielding pattern CA1-2 may be disposed on the bending area BA and may be adjacent to the outside than the bending area BA. The 1-2nd light shielding pattern CA1-2 may fill a space between the bending area BA and the coating window DW. The coating window DW may be directly disposed on the upper surface of the 1-2nd light shielding pattern CA1-2.

[0137] The 1-2nd light shielding pattern CA1-2 may cover the bending area BA. The top of the 1-2nd light shielding pattern CA1-2 may be in contact with the coating window DW. The 1-2nd light shielding pattern CA1-2 may be in contact with the bending protection layer SNL. The second thickness T2 of the 1-2nd light shielding pattern CA1-2 may be greater than the sum of the first thickness T1 of the 1-1st light shielding pattern CA1-1 and the thickness of the display module DM. The outermost surface of the 1-2nd light shielding pattern CA1-2 may be arranged in the second direction DR2 between the most outwardly protruding portion LDP in the bending area BA and the outermost surface of the coating window DW.

[0138] The 1-3rd light shielding pattern CA1-3 may protrude from the 1-2nd light shielding pattern CA1-2 in the direction opposite to the second direction DR2. The side surface of the 1-3rd light shielding pattern CA1-3 may be aligned with the side surface of the coating window DW in the cross section. The third thickness T3 of the 1-3rd light shielding pattern CA1-3 may be the same as the first thickness T1 of the 1-1st light shielding pattern CA1-1. The coating window DW may be directly disposed on the upper surface of the 1-3rd light shielding pattern CA1-3.

[0139] The 1-4th light shielding patterns CA1-4 may be arranged between the bending area BA and the side surfaces of the first protective layer PF1, the second protective layer PF2 and the protection panel CP. The 1-4th light shielding patterns CA1-4 may fill the space separated between the first protective layer PF1 and the bending area BA of the display panel DP. The 1-4th light shielding patterns CA1-4 may overlap the bending area BA. The 1-4th light shielding patterns CA1-4 may contact the bottom surface DP-LS of the display panel DP. The 1-4th light shielding patterns CA1-4 may contact the bending area BA and the side surfaces of the first protective layer PF1, the second protective layer PF2 and the protection panel CP.

[0140] In the case where the coating window DW is formed by coating a resin material such as a resin and then curing it, it may be impossible to additionally bond the light shielding pattern BM to the back side of the coating window DW. Figure 5a When the first light shielding pattern CA1 is formed as shown, even if the light shielding pattern BM is combined with the back of the coating window DW, the first light shielding pattern CA1 can cover the bending area BA. Therefore, the bending area BA and the bending protection layer SNL cannot be recognized from the outside by the first light shielding pattern CA1.

[0141] The coating window DW can be directly arranged on the optical unit ARU and the shading pattern BM. The coating window DW can be formed by coating a resin material such as a resin and curing it. A step corresponding to the shading pattern BM can be defined below the coating window DW. Despite the step below, the top of the coating window DW can also be flat. The outer side surface of the coating window DW can be aligned with the outer side surface of the 1st to 3rd shading pattern CA1-3.

[0143] The protective panel CP may include a third adhesive layer AM3, a barrier layer BF, a fourth adhesive layer AM4, a buffer layer CU, and a fifth adhesive layer AM5. The barrier layer BF may be bonded to the bottom of the first protective layer PF1 through the third adhesive layer AM3. The barrier layer BF may have a color with low light transmittance to prevent identification of components under the barrier layer BF.

[0144] The barrier layer BF may include a flexible synthetic resin film. For example, the barrier layer BF may be a film including polyimide (PI), polyethylene terephthalate (PET), etc. However, the material of the barrier layer BF is not limited thereto and may have various materials as required.

[0145] The buffer layer CU may be bonded to the bottom of the barrier layer BF through the fourth adhesive layer AM4. The buffer layer CU may absorb the impact transmitted from the bottom of the display panel DP. The buffer layer CU may be a highly elastic material such as a foam sheet having a plurality of openings.

[0146] The support panel SSP may be disposed below the protection panel CP to support the display panel DP and the protection panel CP. The support panel SSP may be a metal plate having a rigidity greater than a predetermined reference. For example, the support panel SSP may be a stainless steel plate. The support panel SSP may have a black color in order to block external light incident on the display panel DP.

[0148] Reference Figure 5b The display device DD may be stacked in the order of a support panel SSP, a protection panel CP, a first protection layer PF1, a display panel DP, an optical unit ARU, a light shielding pattern BM, and a coating window DW. Figure 5a different, Figure 5b It is not adjacent to the bending area BA, so there may be no driving control module DCM, the second protection layer PF2 and the bending area BA. Figure 5a The same structures are given the same reference numerals and their descriptions are omitted.

[0149] Each of the second frame area BZA2 and the fourth frame area BZA4 may be configured adjacent to both sides of the transmission area TA. It may be that the second frame area BZA2 corresponds to the second shading pattern CA2, and the fourth frame area BZA4 corresponds to the fourth shading pattern CA4. The outermost surface on the cross section of the second frame area BZA2 may protrude outward compared to the outer side surface of the first protective layer PF1, the outer side surface of the protection panel CP, and the outer side surface of the support panel SSP. The outermost surface on the cross section of the fourth frame area BZA4 may protrude outward compared to the outer side surface of the first protective layer PF1, the outer side surface of the protection panel CP, and the outer side surface of the support panel SSP. Thus, the structure below the shading pattern BM in the second frame area BZA2 and the fourth frame area BZA4 can be prevented from being recognized from the outside.
