[0032] In the current transparent display device, driving circuits are usually arranged in the non-display area, which causes the difference in transmittance between the display area and the non-display area, so that the non-display area appears obvious dark part, resulting in poor display of the transparent display device. The present application proposes a display panel and a display device based on the above technical problem.

[0033] Please refer to FIG. 1 to FIG. 16, the present application proposes a display panel 100, which includes a display part 10 and a driving part 20 arranged on at least one side of the display part 10; for example, the structure of FIG. 1, the display panel 100 includes two driving parts 20, and the display part 10 is arranged between the two driving parts 20.

[0036] In the embodiment, the ratio of the area of the first light-transmitting part 112 to the area of the corresponding display unit 110 is equal to the ratio of the area of the second light-transmitting part 212 to the area of the corresponding driving unit 210.

[0037] The present application sets the first light-transmitting part 112 in the display part 10 and the second light-transmitting part 212 in the driving part 20, and the area ratio of the first light-transmitting part 112 in the display unit 110 is the same as the area ratio of the second light-transmitting part 212 in the driving unit 210, so that the light transmittance in the display part 10 and the light transmittance in the driving part 20 are the same, and the technical problem of the difference in transmittance between the display area and the non-display area in the existing display panel 100 is improved.

[0038] It should be noted that the first light-emitting device D1 can be an organic light-emitting diode, a Micro LED, or a Mini LED, etc. In the following embodiments, the first light-emitting device D1 is taken as a Micro LED for example.

[0039] It should be noted that one display unit 110 of the present application can be provided with one or more first light-emitting devices D1, for example, in the structure of FIG. 1, each first line part 111 can include three first light-emitting devices D1 arranged along the first direction X; the light-emitting colors of the three first light-emitting devices D1 are different from each other, respectively red, green and blue.

[0041] It should be noted that the "equal" of the present application can be absolute equality, and due to the process error in the production process, absolute equality cannot be guaranteed, so that error or process assembly process fluctuation can be tolerated, and the "equal" of the present application can be approximately equal.

[0042] The technical solutions of the present application will be described in conjunction with specific embodiments.

[0043] Referring to Fig. 1, a plurality of display units 110 are arranged in an array in a first direction X and a second direction Y, each display unit 110 comprising a first circuit portion 111 and a first light-transmitting portion 112, in a display unit 110, the first circuit portion 111 and the first light-transmitting portion 112 are arranged along the second direction Y; in the first direction X, the first circuit portions 111 of two display units 110 are arranged adjacently, the first light-transmitting portions 112 of two display units 110 are arranged adjacently, a plurality of first circuit portions 111 form a first circuit row in the first direction X, a plurality of first light-transmitting portions 112 form a first light-transmitting row in the first direction X, a plurality of first circuit rows and a plurality of first light-transmitting rows are arranged in the second direction Y.

[0044] Referring to Fig. 1, a plurality of drive units 210 are arranged in an array in a first direction X and a second direction Y, each drive unit 210 comprising a second circuit portion 211 and a second light-transmitting portion 212, in a drive unit 210, the second circuit portion 211 and the second light-transmitting portion 212 are arranged along the second direction Y; in the first direction X, the second circuit portions 211 of two drive units 210 are arranged adjacently, the second light-transmitting portions 212 of two drive units 210 are arranged adjacently, a plurality of second circuit portions 211 form a second circuit row in the first direction X, a plurality of second light-transmitting portions 212 form a second light-transmitting row in the first direction X, a plurality of second circuit rows and a plurality of second light-transmitting rows are arranged in the second direction Y.

[0045] Referring to Fig. 1, a first circuit row and a second circuit row are arranged in the same row, a first light-transmitting row and a second light-transmitting row are arranged in the same row; that is, in the plurality of display units 110 and the plurality of drive units 210 in the first direction X, the plurality of first circuit portions 111 and the plurality of second circuit portions 211 are arranged in sequence along the first direction X, the plurality of first light-transmitting portions 112 and the plurality of second light-transmitting portions 212 are arranged in sequence along the first direction X.

[0046] In the embodiment, the area of a display unit 110 and the area of a drive unit 210 are equal, the area of a first light-transmitting portion 112 and the area of a second light-transmitting portion 212 are equal, and the area of a first circuit portion 111 and the area of a second circuit portion 211 are equal; that is, the length and width of the first light-transmitting portion 112 can be equal to the length and width of the second light-transmitting portion 212, and the length and width of the first circuit portion 111 can be equal to the length and width of the second circuit portion 211.

[0047] In the embodiment, the first line part 111 and the first light-transmitting part 112 in the display unit 110 are equal in size to the corresponding second line part 211 and the second light-transmitting part 212 in the driving unit 210, so that the area ratio of the light-transmitting area in the display part 10 and the driving part 20 in the corresponding unit is equal, thereby realizing that the display part 10 and the driving part 20 have equal or similar transmittance, and improving the technical problem of poor display of the transparent display device.

[0048] It should be noted that the area of the display unit 110 and the area of the driving unit 210 are equal only in one embodiment of the present application, and the area of the display unit 110 and the area of the driving unit 210 can not be equal, as long as the area ratio of the first light-transmitting part 112 in the display unit 110 and the second light-transmitting part 212 in the driving unit 210 is equal or similar.

[0049] Referring to FIG. 2, each display unit 110 is provided with three first light-emitting devices D1 and three pixel circuits connected with the corresponding first light-emitting devices D1, and the three pixel circuits constitute the first line part 111; in the embodiment, the structures of the three pixel circuits can be the same, for example, the pixel circuit can be a circuit structure of x1Tx2C, x1 can be an integer of 2 to 10, and x2 can be an integer of 1 to 4, which is not limited in the present application.

[0050] Referring to FIG. 3, the first line part 111 can include a first substrate 113 and an array layer 114 located on the first substrate 113. The material of the first substrate 113 can be glass, quartz or polyimide and the like.

[0051] Referring to FIG. 3, the array layer 114 can include a plurality of thin film transistors. The thin film transistor can be an etch stop type, a back channel etch type, or divided into a bottom gate thin film transistor, a top gate thin film transistor and the like according to the position of the gate and the active layer 114C. For example, the bottom gate thin film transistor type thin film transistor can include a buffer layer 114H located on the first substrate 113, a gate layer 114A provided on the buffer layer 114H, a gate insulating layer 114B located on the gate layer 114A, an active layer 114C located on the gate insulating layer 114B, an interlayer insulating layer 114G located on the active layer 114C, a source-drain layer 114D provided on the interlayer insulating layer 114G, a planar layer 114E located on the source-drain layer 114D, a pixel electrode layer 114F located on the planar layer 114E, and a first light-emitting device D1 located on the pixel electrode layer 114F, the first light-emitting device D1 and the pixel electrode layer 114F are electrically connected, and in the structure of FIG. 3, the array layer 114 of the present application is provided with three conductive layers and four insulating layers.

[0052] Alternatively, referring to FIG. 4, the thin film transistor of the bottom-gate thin film transistor type can include a buffer layer 114H on the first substrate 113, a gate layer 114A disposed on the buffer layer 114H, a gate insulating layer 114B on the gate layer 114A, an active layer 114C on the gate insulating layer 114B, an interlayer insulating layer 114G on the active layer 114C, a source-drain layer 114D disposed on the interlayer insulating layer 114G, and a first light emitting device D1 on the source-drain layer 114D, the source-drain layer 114D can include a bonding terminal, and the first light emitting device D1 and the bonding terminal in the source-drain layer 114D are electrically connected, in the structure of FIG. 4, the array layer 114 of the present application is provided with two conductive layers and three insulating layers.

[0053] In the present embodiment, since the metal lines in the display part 10 converge in the first line part 111, in order to avoid shorting of the lines in the same layer, the array layer 114 of the present application can also be provided with four or more conductive layers, for example, in the structures of FIG. 5 and FIG. 6, the array layer 114 of the present application can be provided with four conductive layers and five insulating layers.

[0054] It should be noted that the plurality of conductive layers of the present application can include a metal film layer, and the metal film layer is non-overlapping with the first light-transmitting part 112, i.e., the metal film layer is not provided in the first light-transmitting part 112; similarly, the metal film layer is also not provided in the second light-transmitting part 212, and the first light-transmitting part 112 and the second light-transmitting part 212 only have insulating film layers.

[0055] In the present embodiment, the first light-transmitting part 112 includes at least one insulating layer, and the number of insulating layers in the first light-transmitting part 112 is less than or equal to the number of insulating layers in the first line part 111.

[0056] For example, in the structure shown in FIG. 5, the first light-transmitting part 112 and the first line part 111 each include a first insulating layer 116A, a second insulating layer 116B, a third insulating layer 116C, a fourth insulating layer 116D, and a fifth insulating layer 116E disposed on the first substrate 113, the number of insulating layers in the first light-transmitting part 112 and the first line part 111 is equal, and the first insulating layer 116A, the second insulating layer 116B, the third insulating layer 116C, the fourth insulating layer 116D, and the fifth insulating layer 116E are all transparent insulating materials, and the five insulating layers in the first light-transmitting part 112 and the corresponding insulating layers in the first line part 111 can be formed in the same process.

[0057] For example, in the structure shown in FIG. 6, the first line portion 111 includes a first insulating layer 116A, a second insulating layer 116B, a third insulating layer 116C, a fourth insulating layer 116D and a fifth insulating layer 116E disposed on the first substrate 113, the first light-transmitting portion 112 includes the first insulating layer 116A disposed on the first substrate 113, the number of insulating layers in the first light-transmitting portion 112 is less than the number of insulating layers in the first line portion 111, and the first insulating layer 116A, the second insulating layer 116B, the third insulating layer 116C, the fourth insulating layer 116D and the fifth insulating layer 116E are all transparent insulating materials, and the first insulating layer 116A in the first light-transmitting portion 112 and the first insulating layer 116A in the first line portion 111 can be formed in the same process.

[0058] It should be noted that although the first insulating layer 116A, the second insulating layer 116B, the third insulating layer 116C, the fourth insulating layer 116D and the fifth insulating layer 116E are all transparent insulating materials, the transmittance of the material itself does not reach 100%, so in order to increase the transmittance of the first light-transmitting portion 112, for the structure in FIG. 6, the second insulating layer 116B, the third insulating layer 116C, the fourth insulating layer 116D and the fifth insulating layer 116E in the first light-transmitting portion 112 are removed based on FIG. 5; at the same time, since the first insulating layer 116A is in contact with the first substrate 113, if the first insulating layer 116A is removed, the first substrate 113 may be damaged, therefore the structure in FIG. 6 can retain the first insulating layer 116A, or the thickness of the first insulating layer 116A in the first light-transmitting portion 112 in FIG. 6 can be less than the thickness of the first insulating layer 116A in the first line portion 111, that is, only part of the first insulating layer 116A can be etched.

[0059] In this embodiment, at least one signal transmission line extending in the second direction Y can be provided between two adjacent display units 110; for example, in the structure shown in FIG. 2, two first transmission lines 118 can be provided between two adjacent display units 110, and the first transmission lines 118 can be compensation signal lines, data lines or other transmission lines.

[0060] Referring to FIGS. 5 and 6, the display panel 100 further includes a protective glue 117 disposed on the array layer 114, and the protective glue 117 covers the first light-emitting device D1 in the first line portion 111 and the insulating layers in the first light-transmitting portion 112; at the same time, in the structure of FIG. 6, since the second insulating layer 116B to the fifth insulating layer 116E in the first light-transmitting portion 112 are removed, the protective glue 117 fills the space on the first insulating layer 116A in the first light-transmitting portion 112, so that the flatness of the film layers in the first line portion 111 and the first light-transmitting portion 112 is the same.

[0061] It should be noted that the insulating layers in the first circuit portion 111 and the first light-transmitting portion 112 are formed in the same process and have the same thickness. The thickness of the same insulating layer at different positions in FIGS. 5 and 6 is not the same, which is only a schematic diagram.

[0062] Referring to FIG. 7, each driving unit 210 is provided with three second light-emitting devices D2 and a gate drive circuit disposed between the three second light-emitting devices D2 and the first substrate 113. The second light-emitting devices D2 and the corresponding gate drive circuit are insulated.

[0063] In the present embodiment, since the display portion 10 is provided with a plurality of first light-emitting devices D1, in order to ensure the uniformity of the display panel 100, the present application is also provided with a plurality of second light-emitting devices D2 in the driving portion 20. The number density of the second light-emitting devices D2 is the same as that of the first light-emitting devices D1. The distribution density of the second light-emitting devices D2 in the driving portion 20 is the same as that of the first light-emitting devices D1 in the display portion 10, thereby ensuring the uniformity of the light-emitting devices in the display panel 100.

[0064] In the present embodiment, since the second circuit portion 211 includes a gate drive circuit, the wiring inside is relatively dense, and there is no extra space to set a pixel circuit for controlling the light-emitting of the second light-emitting device D2. Therefore, the gate drive circuit of the present application is insulated from the second light-emitting device D2.

[0065] In the present embodiment, the structure of the second light-emitting device D2 can be the same as that of the first light-emitting device D1. In one driving unit 210, the light-emitting colors of the three second light-emitting devices D2 are different from each other, and are one of red, green and blue. Since the second light-emitting device D2 does not emit light, the light-emitting colors of all the second light-emitting devices D2 can be the same.

[0066] In the embodiment, since the number of transistors in the gate drive circuit is large and the circuit is complex, the space of the original part of the gate drive circuit wiring is used to set the second light transmission part 212, so that the gate drive circuit of the application can be rearranged by reducing the size in the second direction Y and increasing the size in the first direction X; in the structure of FIG. 7, the size of one second circuit part 211 in the first direction X cannot meet the size requirement of the gate drive circuit in the first direction X, so the application can use two or more second circuit parts 211 to arrange the gate drive circuit of the application, for example, in the structure of FIG. 8, the gate drive circuit of each stage can occupy three second circuit parts 211 arranged along the first direction X, and since different control signals are output by different gate drive circuits, FIG. 8 lists two gate drive circuits occupying three second circuit parts 211 respectively; or six second circuit parts 211 arranged along the first direction X in FIG. 8 are occupied by the same gate drive circuit.

[0067] In the embodiment, the gate drive circuit can be a circuit structure of x3Tx4C, x3 can be an integer of 2 to 20, and x4 can be an integer of 1 to 4, which is not limited by the application.

[0068] In the embodiment, the film layer structure in the driving part 20 can be the same as that in the display part 10, and each same film layer can be formed in the same film sinking process, which is not limited by the application.

[0069] In the structure of FIG. 7, at least one signal transmission line extending along the second direction Y can be arranged between the two adjacent driving units 210; for example, in the structure shown in FIG. 2, two second transmission lines 218 can be arranged between the two adjacent driving units 210, which can be constant voltage high level lines, constant voltage low level lines, clock signal lines or other transmission lines.

[0070] It should be noted that in order to reduce the impedance of the vertical wiring in the conventional driving part 20, the width of the vertical transmission line is usually wide, and since the layout of the driving part 20 of the application is the same as that of the display part 10, there is not enough width between the two adjacent driving units 210 to set the vertical wiring; and the conductive layer of the application has multiple layers of conductive layers, and each vertical wiring can be set by 2 or more layers of conductive layer stacks, that is, by connecting the multiple layers of conductive layers in parallel to reduce the impedance of the vertical wiring.

[0071] It should be noted that, since the second line part 211 in the driving part 20 is a non-display area, the driving part 20 of the present application can not need to be provided with the second light emitting device D2; or, a pixel circuit electrically connected with the second light emitting device D2 can be provided in the display part 10 to make the second light emitting device D2 emit light.

[0072] Referring to FIGS. 5 and 6, in order to reduce the reflectivity of the conductive metal film layer, the first line part 111 of the present application can further include a first light shielding layer 119, the first light shielding layer 119 being arranged between the first light emitting device D1 and the array layer 114, and a normal projection of the first light shielding layer 119 on the array layer 114 being located in the array layer 114; the first light shielding layer 119 of the present application completely shields the first line part 111, and the area of the first light shielding layer 119 can be equal to the area of the first line part 111 to avoid the reflection of the metal in the first line part 111; similarly, the second line part 211 can further be provided with a third light shielding layer (not shown), the third light shielding layer completely shielding the second line part 211, and the area of the third light shielding layer can be equal to the area of the second line part 211 to avoid the reflection of the metal in the second line part 211.

[0073] In the display panel 100 of the present application, the ratio of the sum of the areas of the plurality of first line parts 111 to the area of the display panel 100 ranges from 0.1 to 0.5; that is, the sum of the areas for light emitting display in the display panel 100 of the present application can account for 10% to 50% of the area of the display panel 100, and the sum of the areas for non-light emitting display in the display panel 100 of the present application can account for 50% to 90% of the area of the display panel 100.

[0074] It should be noted that, since the first line part 111 and the second line part 211 are provided with the metal film layer, the light transmittance of the first line part 111 of the present application is less than the light transmittance of the first light transmissive part 112, and the light transmittance of the second line part 211 is less than the light transmittance of the second light transmissive part 212; at the same time, the light transmittance of the first line part 111 and the light transmittance of the second line part 211 are further reduced due to the arrangement of the first light shielding layer 119 and the third light shielding layer.

[0075] Referring to FIG. 8, the display panel 100 further includes an electrostatic discharge part 30 arranged between the display part 10 and the driving part 20, the electrostatic discharge part 30 including a plurality of electrostatic discharge units 310, each electrostatic discharge unit 310 including a third line part 311 and a third light transmissive part 312, the third line part 311 including an electrostatic protection device 311A for discharging static electricity; the ratio of the area of the third light transmissive part 312 to the area of the corresponding electrostatic discharge unit 310 is equal to the ratio of the area of the second light transmissive part 212 to the area of the corresponding driving unit 210.

[0076] In the embodiment, since the metal wire layout in the driving part 20 and the display part 10 is relatively dense, the technical problem of static electricity concentration is prone to occur in the driving part 20 or the display part 10; the static electricity in the driving part 20 or the display part 10 can be released by the static electricity release unit 310, so as to avoid the technical problem that the device is damaged due to the static electricity concentration in the driving part 20 or the display part 10.

[0077] It should be noted that three static electricity release parts 30 are listed in FIG. 8, and each static electricity release part 30 occupies one third line part; meanwhile, the static electricity release part 30 in FIG. 8 can be a chip peripheral wire, a ground wire or other line layout.

[0078] Referring to FIGS. 9A-9E, the display device 400 includes a panel area 400A and a non-panel area 400B located at least one side of the panel area 400A, the panel area 400A is provided with the display panel 100 shown in FIG. 1, and the non-panel area 400B is not provided with the display panel 100 shown in FIG. 1, and is only a transparent structure.

[0079] In the structure of FIGS. 9A-9E, the position of the panel area 400A can be set at the upper side, the lower side, the left side, the right side or the central area of the display device 400, and the application does not make specific limitation.

[0080] Referring to the structures shown in FIGS. 10 and 11, the display device 400 includes a second substrate 410, an encapsulation cover plate 420 arranged opposite to the second substrate 410, and the display panel 100 arranged between the second substrate 410 and the encapsulation cover plate 420.

[0081] In the structure of FIGS. 10 and 11, the display device 400 further includes a first adhesive 430 and a second adhesive 440 arranged between the second substrate 410 and the encapsulation cover plate 420. For example, in FIG. 10, the first adhesive 430 is arranged between the display panel 100 and the second substrate 410, the second adhesive 440 is arranged between the second substrate 410 and the encapsulation cover plate 420, and covers the surface of the display panel 100 away from the second substrate 410; in FIG. 11, the first adhesive 430 is arranged between the display panel 100 and the second substrate 410, and the first adhesive 430 is arranged between the display panel 100 and the encapsulation cover plate 420, the second adhesive 440 is arranged in the non-panel area 400B, and the second adhesive 440 is arranged between the second substrate 410 and the encapsulation cover plate 420.

[0082] In the display device 400 of the application, the first adhesive 430 can be transparent or non-transparent adhesive, the second adhesive 440 can be transparent adhesive, and the refractive index of the first adhesive 430 and the second adhesive 440 can be equal or close, for example, the refractive index difference of the adhesive is within 0.1.

[0083] In the embodiment, since the second adhesive 440 is mainly arranged in the non-panel area 400B and the first adhesive 430 is mainly arranged in the panel area 400A, when the display panel 100 is bonded between the second substrate 410 and the encapsulation cover plate 420, the first adhesive 430 can be liquid adhesive and the second adhesive 440 can be liquid or solid adhesive; meanwhile, since the second adhesive 440 is in the panel area 400A, the area of the region illuminated by light is large, and the first adhesive 430 is in the panel area 400A, part of the light is blocked by the display panel 100, so the solidification rate of the first adhesive 430 can be less than that of the second adhesive 440.

[0084] In the structure of FIGS. 10 and 11, the display device 400 further comprises a frame adhesive 480 arranged between the second substrate 410 and the encapsulation cover plate 420, and the frame adhesive 480 is arranged along the periphery of the display device 400 to seal the display device 400.

[0085] It should be noted that, in order to ensure that the panel area 400A and the non-panel area 400B of the display device 400 have the same or similar transparency, the transmittance and reflectivity of the panel area 400A and the non-panel area 400B need to be the same or similar, and therefore the number of light rays emitted from the unit area of the light emitting surface in the panel area 400A is equal to the number of light rays emitted from the unit area of the light emitting surface in the non-panel area 400B, that is, the light rays reflected and transmitted from the unit area of the light emitting surface in the non-panel area 400B need to be equal to or similar to the light rays reflected and transmitted from the unit area of the light emitting surface in the panel area 400A.

[0086] For example, for adjusting the reflectivity, referring to FIG. 12, the display device 400 can further comprise a reflection adjusting layer 450 arranged in the non-panel area 400B, the reflection adjusting layer 450 is arranged between the second substrate 410 and the encapsulation cover plate 420, and the reflectivity of the reflection adjusting layer 450 is positively correlated with the reflectivity of the display panel 100.

[0087] In the structure of FIG. 11, in the non-panel area 400B, the interface between the second adhesive 440 and the encapsulation cover plate 420 has a first reflectivity S1, the surface of the second substrate 410 away from the second adhesive 440 has a second reflectivity S2, and the first reflectivity S1 and the second reflectivity S2 have a first product. Meanwhile, in the panel area 400A, the interface between the display panel 100 and the first adhesive 430 has a third reflectivity S3, the surface of the second substrate 410 away from the second adhesive 440 has a fourth reflectivity S4, and the third reflectivity S3 and the fourth reflectivity S4 have a second product. Finally, the reflection adjusting layer 450 has a fifth reflectivity S5, and the quotient of the second product and the first product is the fifth reflectivity S5, that is, the fifth reflectivity S5 can be (S3*S4) / (S1*S2).

[0088] It should be noted that the second reflectivity S2 and the fourth reflectivity S4 are both the reflectivity of the surface of the second substrate 410 away from the second adhesive 440, but since the reflectivity is the result of multiple interface reflections, the second reflectivity S2 and the fourth reflectivity S4 are not necessarily equal.

[0089] It should be noted that the reflectivity of each section in FIG. 12 increases the first AR layer 471 and the second AR layer 472, and since the reflectivity S0 of the first AR layer 471 in different regions is the same, the above formula removes the reflectivity S0.

[0090] For the transmittance, the light transmittance in the panel area 400A of the display device 400 is equal to the light transmittance in the non-panel area 400B. For example, referring to FIG. 13, the display device 400 further includes a second light shielding layer 460 disposed in the non-panel area 400B, and the area of the second light shielding layer 460 is less than the area of the non-panel area 400B; the ratio of the area of the second light shielding layer 460 to the area of the non-panel area 400B is equal to the ratio of the area of the first light shielding layer 119 to the area of the corresponding display unit 110.

[0091] Since the first light shielding layer 119 is disposed in each first circuit portion 111 of the display panel 100, and the third light shielding layer is disposed in each second circuit portion 211, the transmittance in the display panel 100 is the ratio of the sum of the areas of the plurality of first light-transmitting portions 112 and the plurality of second light-transmitting portions 212 to the area of the display panel 100; and since the non-panel area 400B is a light-transmitting region, the transmittance in the non-panel area 400B is not equal to the transmittance in the panel area 400A, thereby causing the display effect of different regions of the display device 400 to have certain differences.

[0092] In the present embodiment, the second light shielding layer 460 can include a plurality of light shielding strips 461, which extend along the first direction X and are arranged at intervals along the second direction Y, such as the structure of FIG. 13; or the plurality of light shielding strips 461 extend along the second direction Y and are arranged at intervals along the first direction X; the arrangement of the second light shielding layer 460 of the present application reduces the transmittance of the non-panel area 400B, so that the transmittance in the non-panel area 400B and the panel area 400A is the same, thereby improving the technical problem that the display effect of different regions of the display device 400 has differences.

[0093] Please refer to FIG. 14 to FIG. 15, in the structure of FIG. 14, the reflection adjustment layer 450 is arranged on the side of the packaging cover plate 420 facing the second substrate 410, and the second light shielding layer 460 is arranged on the side of the second substrate 410 facing the packaging cover plate 420; in the structure of FIG. 15, the second light shielding layer 460 is arranged on the side of the packaging cover plate 420 facing the second substrate 410, and the reflection adjustment layer 450 is arranged on the side of the second substrate 410 facing the packaging cover plate 420. Similarly, the reflection adjustment layer 450 and the second light shielding layer 460 can be arranged on the side of the packaging cover plate 420 facing the second substrate 410, or the reflection adjustment layer 450 and the second light shielding layer 460 can be arranged on the side of the second substrate 410 facing the packaging cover plate 420, and the present application does not make specific limitations.

[0094] Please refer to FIG. 16, the display device 400 of the present application further comprises a first anti-reflection layer 471 and a second anti-reflection layer 472, the first anti-reflection layer 471 is arranged on the side of the packaging cover plate 420 away from the second substrate 410, and the second anti-reflection layer 472 is arranged on the side of the second substrate 410 away from the packaging cover plate 420. The first anti-reflection layer 471 and the second anti-reflection layer 472 in the present application can be AR (Anti-Reflection, anti-reflection) anti-reflection film, which is mainly used to reduce the reflectivity of the surface of the display device 400 and increase the transmittance of the display device 400.
