[0117] A polarization unit ARU may be disposed on the upper surface DP-US of the display panel DP. The polarization unit ARU may overlap with the non-bending area NBA of the display panel DP. The polarization unit ARU may function as a base layer when a resin material such as a resin that forms the coating window DW is coated. In addition, the polarization unit ARU may function as a barrier so that the coating liquid of the coating window DW does not invade the display panel DP.

[0118] A step SP may be defined on the top of the polarization unit ARU. The step SP of the polarization unit ARU may have a shape corresponding to the shape of the light shielding film BMF. The polarization unit ARU may include a first polarization portion ARU1 and a second polarization portion ARU2 extending from the first polarization portion ARU1. The thickness of the first polarization portion ARU1 may be a first thickness T1. The second polarization portion ARU2 may be a portion extending from the first polarization portion ARU1 in the opposite direction of the second direction DR2, that is, the outer direction. The thickness of the second polarization portion ARU2 may be a second thickness T2 less than the first thickness T1. The boundary between the first polarization portion ARU1 and the second polarization portion ARU2 may define a step SP.

[0119] The lower surface of the first polarization unit ARU1 and the lower surface of the second polarization unit ARU2 may form the same surface. A coating window DW may be directly disposed on the upper surface of the first polarization unit ARU1. A light shielding film BMF may be bonded on the upper surface of the second polarization unit ARU2.

[0120] The distance DD2 from the top of the second polarizing part ARU2 to the bottom DP-LS of the display panel DP may be substantially the same as the distance DD1 from the top of the curved protection layer SNL to the bottom DP-LS of the display panel DP. That is, the top of the second polarizing part ARU2 and the top of the curved protection layer SNL may be located at the same position according to the third direction DR3. Therefore, when the light shielding film BMF is bonded to the top of the second polarizing part ARU2 and the top of the curved protection layer SNL, they may be stably placed.

[0121] The first polarization part ARU1 and the second polarization part ARU2 may be adhered to the display panel DP through the first adhesive layer AM1. However, the first adhesive layer AM1 may be omitted as needed.

[0122] The side SNL-S of the curved protection layer SNL adjacent to the side of the second polarization part ARU2 may be spaced apart by a predetermined interval. The side of the second polarization part ARU2 may be adjacent to the center of the non-bending area NBA than the side SNL-S of the curved protection layer SNL adjacent thereto. Thus, the side SNL-S of the curved protection layer SNL and the side of the second polarization part ARU2 adjacent thereto may be prevented from colliding during the bending process.

[0123] The bending protection layer SNL may be disposed on the display panel DP. The bending protection layer SNL may overlap the bending area BA and bend together with the bending area BA of the display panel DP. A portion of the bending protection layer SNL may overlap a portion of the non-bending area NBA of the display panel DP. The bending protection layer SNL may prevent the bent portion of the display panel DP from being damaged due to external impact or external foreign matter from flowing in.

[0124] The bending protection layer SNL may be disposed on the front surface of the display panel DP to protect the bent portion of the display panel DP. The bending protection layer SNL may include a plastic film as a base layer. The bending protection layer SNL may include a plastic film selected from the group consisting of polyethersulfone (PES), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyallylate, polyimide (PI), polycarbonate (PC), polyarylene ether sulfone (poly(aryleneether sulfone)) and combinations thereof.

[0125] However, the material constituting the bending protection layer SNL is not limited to plastic resin, and may include an organic / inorganic composite material. The bending protection layer SNL may include a porous organic layer and an inorganic substance filling pores in the organic layer. The bending protection layer SNL may include a single layer or a multilayer structure.

[0126] A drive control module DCM may be combined at the end of the display panel DP. The drive control module DCM may include a first circuit substrate FCB1, a panel drive circuit PDC, and a main circuit substrate MCB. The first circuit substrate FCB1 may electrically connect the main circuit substrate MCB and the display panel DP, and is installed with a panel drive circuit PDC. In this embodiment, a situation where the panel drive circuit PDC is installed on the first circuit substrate FCB1 is shown, but the position of the panel drive circuit PDC may not be limited thereto. For example, the panel drive circuit PDC may be directly configured on the upper surface DP-US of the display panel DP.

[0127] The first circuit substrate FCB1 may be electrically connected to the signal pad PD. Figure 3 The pad area NDA-PD (refer to Figure 3 ) corresponds to the signal pad PD.

[0128] The second protection film PF2 may be respectively combined with the end of the display panel DP and the driving control module DCM. When the display panel DP is bent, one side of the second protection film PF2 may contact the sixth adhesive layer AM6.

[0129] The light shielding film BMF may be bonded to the upper surface of the curved protection layer SNL and the second polarization part ARU2. The light shielding film BMF may be bonded to the step SP. The light shielding film BMF may cover the curved portion of the display panel DP on a plane. The light shielding film BMF may cover the curved portion of the curved protection layer SNL on a plane. The light shielding film BMF may be bonded to a portion of the upper surface of the curved protection layer SNL and the upper surface of the second polarization part ARU2 through a first lower adhesive layer AM0.

[0130] The light shielding film BMF may extend in the second direction DR2 and may be a hard substrate including a light shielding material. The light shielding film BMF may function as a base layer when a resin material is applied to form the coating window DW. The light shielding film BMF may function as a barrier to prevent the resin material in a liquid state from penetrating into the curved portion of the display panel DP or the curved portion of the curved protection layer SNL.

[0131] The sum of the thickness of the light shielding film BMF and the thickness of the first lower adhesive layer AM0 may be substantially the same as the difference between the first thickness T1 and the second thickness T2. That is, the upper surface of the light shielding film BMF and the upper surface of the polarization unit ARU may be aligned in cross section.

[0132] The side surface of the light shielding film BMF may contact the step SP of the polarizing unit ARU. That is, there may be no space between the side surface of the light shielding film BMF and the step SP of the polarizing unit ARU. Therefore, even if a resin material is applied to form a coating window DW on the upper surface of the light shielding film BMF and the upper surface of the polarizing unit ARU, the resin material cannot penetrate into the display panel DP.

[0133] The outer side surface BMF-0 of the light shielding film BMF can be aligned with the outer side surface DW-0 of the coating window DW in the cross section. That is, the outer side surface BMF-0 of the light shielding film BMF and the outer side surface DW-0 of the coating window DW can be arranged on a straight line in the cross section. Therefore, the separation of the coating window DW and the light shielding film BMF due to external impact can be minimized.

[0134] The coating window DW may be directly disposed on the polarizing unit ARU and the light shielding film BMF. That is, the coating window DW may be disposed on the polarizing unit ARU and the light shielding film BMF without a separate adhesive layer or adhesive component. The coating window DW may include a substance that is cured by laser irradiation. The coating window DW may be formed by coating a resin substance such as an optically transparent resin and curing the coated resin substance.

[0135] The light shielding film BMF may cover the curved portion of the curved protection layer SNL on a plane. The light shielding film BMF may cover the curved portion of the display panel DP on a plane. Therefore, the curved portion of the display panel DP and the curved portion of the curved protection layer SNL may not be recognized from the outside.

[0136] The outer side surface BMF-0 of the light shielding film BMF may protrude outwardly from a point LSNL most separated from the non-bending area NBA in the curved portion of the bending protection layer SNL. The outer side surface BMF-0 of the light shielding film BMF may be separated from the non-bending area NBA farther than a point LSNL most separated from the non-bending area NBA in the curved portion of the bending protection layer SNL. The outer side surface BMF-0 of the light shielding film BMF may protrude outwardly from a point LDP most separated from the non-bending area NBA in the curved portion of the display panel DP.

[0137] The position of the point BMF-0 in the light shielding film BMF that is most separated from the non-bending area NBA in the second direction DR2 is defined as a first position H1. The position of the point LSNL in the curved portion of the bending protection layer SNL that is most separated from the non-bending area NBA in the second direction DR2 is defined as a second position H2. The position of the point LDP in the curved portion of the display panel DP that is most separated from the non-bending area NBA in the second direction DR2 is defined as a third position H3. The first position H1 may be set farther from the non-bending area NBA than the second position H2 and the third position H3. The second position H2 may be set farther from the non-bending area NBA than the third position H3.

[0138] When the coating window DW is formed by coating with a resin material such as a resin and then curing it, it is impossible to combine the light shielding pattern BM alone on the back of the coating window DW. Therefore, a hard substrate can be used as the light shielding film BMF, and the light shielding film BMF can be bonded to the bending protection layer SNL and the polarization unit ARU and the resin material can be coated on the light shielding film BMF.

[0139] The first protection film PF1 may be disposed on the first lower surface DP-LS1 of the display panel DP. The first protection film PF1 may be bonded to the first lower surface DP-LS1 through the second adhesive layer AM2. However, the second adhesive layer AM2 may be omitted as needed. The first protection film PF1 may protect the first lower surface DP-LS1 of the display panel DP from external impact.

[0140] The protection panel CP may be disposed on the first lower surface DP-LS1 of the display panel DP and may protect the display panel DP from impact or the like transmitted from below.

[0141] 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 film 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.

[0142] 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.

[0143] 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.

[0144] 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 bonded to the bottom of the buffer layer CU through the fifth adhesive layer AM5. The support panel SSP may be a metal plate having a hardness above a predetermined reference. For example, the support panel SSP may be a stainless steel plate. The support panel SSP may be black in order to block external light incident on the display panel DP.

[0145] Figure 5b is a cross-sectional view of a display device DD according to an embodiment of the present invention.

[0146] Reference Figure 5b , Figure 5b The display device DD is Figure 5a The display device DD described in Figure 5a and Figure 5b ) In addition to the first lower adhesive layer AM0 (refer to Figure 5a ), so the same figure marks are used for the same structures and the description thereof is omitted.

[0147] The light shielding film BMF may be bonded to a portion of the upper surface of the bending protection layer SNL and the upper surface of the second polarization part ARU2 through the second lower adhesive layer AM00. At this time, the light shielding film BMF may be bonded to an area of ​​the upper surface of the bending protection layer SNL in a detachable manner. The second lower adhesive layer AM00 may be bonded to a portion of the upper surface of the bending protection layer SNL and the upper surface of the second polarization part ARU2. Figure 5a The first lower adhesive layer AM0 has weak adhesive force.

[0148] The light shielding film BMF may be detachably bonded to a region on the upper surface of the bending protection layer SNL, and thus the bending protection layer SNL is bent after the light shielding film BMF is bonded to the upper surface of the bending protection layer SNL. Fig.10b as well as Fig.10c Before bending, the bending protection layer SNL can be bent after the light shielding film BMF is bonded on the bending protection layer SNL. The bonding force of the second lower bonding layer AM00 can be so weak that the shape of the light shielding film BMF can be maintained even when only the bending protection layer SNL is bent while the light shielding film BMF and the bending protection layer SNL are bonded. Figures 10a to 10c This will be described in more detail later.

The polarization unit ARU may have a certain thickness and extend in the second direction DR2. The polarization unit ARU may overlap the non-bending area NBA. The end portion of the polarization unit ARU may overlap the frame area BZA. That is, a light shielding pattern BM may be disposed on the end portion of the polarization unit ARU.

[0151] The first auxiliary film BPP may be bonded to the bending protection layer SNL. The lower surface of the first auxiliary film BPP may be bonded to the upper surface of the bending protection layer SNL through the first lower adhesive layer AM0'. The first auxiliary film BPP may overlap the bending area BA and extend in the opposite direction of the second direction DR2. The outer side surface of the polarizing unit ARU and the side surface BPP-S of the first auxiliary film BPP adjacent thereto may be in contact. The upper surface of the first auxiliary film BPP may extend from the upper surface of the polarizing unit ARU.

[0152] A distance DD3 from the top of the first auxiliary film BPP to the first bottom surface DP-LS1 of the display panel DP may be substantially the same as a distance DD4 from the top of the polarizing unit ARU to the first bottom surface DP-LS1 of the display panel DP. That is, the top surface of the first auxiliary film BPP and the top surface of the polarizing unit ARU may extend without a step and form a single plane.

[0153] Therefore, a resin material for forming a coating window DW may be applied on the upper surface of the first auxiliary film BPP and the upper surface of the polarizing unit ARU. That is, the upper surface of the first auxiliary film BPP and the upper surface of the polarizing unit ARU may function as a base layer for forming the coating window DW. At this time, there is no spaced contact between the first auxiliary film BPP and the polarizing unit ARU, thereby preventing the resin material from penetrating into the display panel DP and the bending protection layer SNL.

[0154] The light shielding pattern BM may be directly disposed on the first auxiliary film BPP and the polarizing unit ARU. That is, a separate adhesive layer and adhesive may not be disposed between the light shielding pattern BM and the first auxiliary film BPP. A separate adhesive layer and adhesive may not be disposed between the light shielding pattern BM and the polarizing unit ARU. Figure 5a Light-shielding film BMF (refer to Figure 5a ) is different from that formed by the coating and curing process of the light-shielding material.

The position of the point LSNL in the curved portion of the bending protection layer SNL that is most separated from the non-bending area NBA in the second direction DR2 may be defined as a second position H2. The position of the point LDP in the curved portion of the display panel DP that is most separated from the non-bending area NBA in the second direction DR2 may be defined as a third position H3. The first position H1 may be set farther from the non-bending area NBA than the second position H2 and the third position H3. The second position H2 may be set farther from the non-bending area NBA than the third position H3.

[0161] The first auxiliary film BPP may be detachably bonded to an area on the upper side of the bending protection layer SNL, and thus the bending protection layer SNL is bent after the first auxiliary film BPP is bonded to the upper side of the bending protection layer SNL. Fig.12c as well as Fig.12d Before bending, the bending protection layer SNL can be bent after the first auxiliary film BPP is bonded on the bending protection layer SNL. The adhesive force of the second lower adhesive layer AM00' can be so weak that the shape of the first auxiliary film BPP can be maintained even when only the bending protection layer SNL is bent when the first auxiliary film BPP and the bending protection layer SNL are bonded. Figures 12a to 12d This will be described in more detail later.

[0164] A release agent PSR may be applied to a portion of the second auxiliary film PSF corresponding to the light shielding pattern BM. By applying the release agent PSR between the second auxiliary film PSF and the light shielding pattern BM, the shape of the light shielding pattern BM can be maintained even when only the second auxiliary film PSF is bent while the light shielding pattern BM is disposed on the second auxiliary film PSF. Figures 13a to 13d This will be described in more detail later.

[0165] The thickness of the second auxiliary film PSF coated with the release agent PSR may be substantially the same as the thickness of the polarizing unit ARU. That is, the distance DD5 from the top of the second auxiliary film PSF coated with the release agent PSR to the first bottom surface DP-LS1 of the display panel DP may be substantially the same as the distance DD6 from the top of the polarizing unit ARU to the first bottom surface DP-LS1 of the display panel DP. The top surface of the second auxiliary film PSF coated with the release agent PSR and the top surface of the polarizing unit ARU may serve as a base layer for forming a shading pattern BM.
