Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] In the related art, the technology of using a color filter (CF) layer to replace a polarizer (POL) is usually called a POL-Less technology. For a display panel using the POL-Less technology, the thickness of the display panel can be reduced and the display effect can be improved because the polarizer is omitted.

[0003] The display panel usually includes a light-emitting device layer and a color film layer. The light-emitting device layer includes a plurality of light-emitting devices. The color film layer includes a first light-blocking portion and a second light-blocking portion that allow light of different colors to be emitted. The first light-blocking portion and the second light-blocking portion are successively arranged on the light-emitting devices that emit light of corresponding colors. The materials of the first light-blocking portion and the second light-blocking portion both have poor leveling properties. Since the first light-blocking portion is made first, there are no obstacles around it, so that the first light-blocking portion can be leveled smoothly. Since the second light-blocking portion is made after the first light-blocking portion, and the first light-blocking portion has a relatively large thickness, this has an adverse effect on the leveling of the second light-blocking portion, resulting in a depression on the top of the second light-blocking portion. In this case, the light emitted by the light-emitting device located below the second light-blocking portion converges when passing through the second light-blocking portion, which in turn causes the display panel to have a display abnormality. Summary of the invention

[0004] Embodiments of the present application provide a display panel and a display device, which are used to at least solve the problem of depression on the top of a portion of the light blocking portion in the related art.

[0005] On the one hand, an embodiment of the present application provides a display panel, which includes: a driving substrate, a plurality of light-emitting units disposed on the driving substrate, an encapsulation layer covering the plurality of light-emitting units, and a plurality of light-blocking units disposed on the encapsulation layer. Each light-emitting unit includes a plurality of light-emitting devices emitting different colors; each light-blocking unit includes a plurality of light-blocking portions that allow light of different colors to be emitted, and each light-blocking portion covers a light-emitting device emitting light of a corresponding color. The light-blocking unit also includes at least one flat portion disposed on the encapsulation layer, in which one of the light-blocking portions contacts the encapsulation layer, and at least one of the light-blocking portions is disposed on the flat portion.

[0006] In some embodiments, the light blocking unit includes a first light blocking portion, a second light blocking portion and a third light blocking portion, and two flat portions are provided; in the light blocking unit, the first light blocking portion contacts the encapsulation layer, and the second light blocking portion and the third light blocking portion respectively correspond to one of the flat portions and are arranged on the corresponding flat portions.

[0007] In some embodiments, the light blocking unit includes a first flat portion located below the second light blocking portion, the first flat portion is adjacent to the first light blocking portion, and a thickness of the first flat portion is equal to a thickness of the first light blocking portion.

[0008] In some embodiments, the second light blocking portion is partially located on the first light blocking portion.

[0009] In some embodiments, the light blocking unit further includes a second flat portion located below the third light blocking portion, and a thickness of the second flat portion is greater than a thickness of the first flat portion.

[0010] In some embodiments, a thickness of the second flat portion is equal to a sum of a thickness of the first flat portion and a thickness of the second light blocking portion.

[0011] In some embodiments, the third light blocking portion is partially located on the second light blocking portion.

[0012] In some embodiments, there is a gap between the second flat portion and the first flat portion, and the light blocking unit further includes a first auxiliary light blocker, the first auxiliary light blocker and the first light blocking portion allow light of the same color to be emitted, the first auxiliary light blocker is arranged in the gap, and the second light blocking portion covers the first auxiliary light blocker.

[0013] In some embodiments, the light blocking unit further includes a third auxiliary light blocking unit, the third auxiliary light blocking unit and the third light blocking portion allow light of the same color to be emitted, and along the thickness direction of the display panel, the third auxiliary light blocking unit, the second light blocking portion and the first light blocking portion have an overlapping portion.

[0014] In some embodiments, the display panel also includes a color filter layer, the light blocking unit is located in the color filter layer, and a plurality of touch lines are arranged between the encapsulation layer and the color filter layer; the light-emitting unit is located in the light-emitting device layer, and the orthographic projection of each touch line on the light-emitting device layer is located between two adjacent light-emitting devices.

[0015] In some embodiments, the light blocking portion in contact with the encapsulation layer covers at least one of the touch control traces.

[0016] In some embodiments, along the thickness direction of the display panel, each light blocking portion covers two of the touch control traces, and the orthographic projections of the two touch control traces on the light emitting device layer are located on both sides of the light emitting device below the light blocking portion.

[0017] On the other hand, an embodiment of the present application further provides a display device, which includes the display panel as described in any of the above embodiments.

[0018] For the display panel provided by the embodiment of the present application, since one of the light blocking portions in the light blocking unit contacts the encapsulation layer, and at least one of the light blocking portions in the light blocking unit is disposed on the flat portion, the light blocking portion in contact with the encapsulation layer (hereinafter referred to as the first light blocking portion for ease of explanation) can be manufactured before other light blocking portions, so the first light blocking portion will not be affected by other light blocking portions during the manufacturing process, thereby ensuring that the first light blocking portion can be smoothly leveled. As for the light blocking portion (hereinafter referred to as the selected light blocking portion for ease of explanation) disposed on the flat portion among other light blocking portions, the flat portion below it can reduce the step difference between the bottom of the selected light blocking portion and the top of the surrounding elements of the selected light blocking portion (such as the first light blocking portion), thereby reducing the adverse effect of the surrounding elements of the selected light blocking portion on the leveling property during the manufacturing process of the selected light blocking portion, thereby improving the leveling degree of the selected light blocking portion to ensure the display effect of the display panel.

[0025] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. The described technical solutions are only used to explain and illustrate the ideas of the present application and should not be regarded as limiting the scope of protection of the present application.

[0026] In the description of this application, it should be understood that the terms "first", "second" and similar words do not indicate any order, quantity or importance, but are only used to distinguish different technical features. The term "plurality" and similar words mean two or more, unless otherwise clearly defined.

[0027] “A and / or B” includes the following three combinations: A only, B only, and a combination of A and B.

[0028] The use of "suitable for" or "configured to" in this application is meant to be open and inclusive language, which does not exclude devices that are suitable for or configured to perform additional tasks or steps. In addition, the use of "based on" is meant to be open and inclusive, because the process, step, calculation or other action "based on" one or more stated conditions or values ​​can be based on additional conditions or values ​​beyond the stated values ​​in practice.

[0029] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present application.

[0030] The various embodiments of the present application are similar, and features in different embodiments and / or different examples may be combined with each other.

[0031] In related technologies, such as Figure 1As shown, the display panel includes a light-emitting device layer 01 and a color filter layer 02, the light-emitting device layer 01 includes a plurality of light-emitting devices 011 with different light-emitting colors, and the color filter layer 02 includes a first light-blocking portion 021, a second light-blocking portion 022, and a third light-blocking portion 023 that allow light of different colors to be emitted. The first light-blocking portion 021, the second light-blocking portion 022, and the third light-blocking portion 023 are successively arranged on the light-emitting device 011 that emits light of corresponding colors. The materials of the first light-blocking portion 021, the second light-blocking portion 022, and the third light-blocking portion 023 all have poor leveling properties. Since the first light-blocking portion 021 is made first, there are no thick obstacles around it, so that the first light-blocking portion 021 can be leveled smoothly. However, the second photoresist portion 022 and the third photoresist portion 023 are sequentially manufactured after the first photoresist portion 021, and the second photoresist portion 022 is located between the first photoresist portion 021 and the third photoresist portion 023. The first photoresist portion 021 has a relatively large thickness (usually up to 3 μm) after being manufactured, which has an adverse effect on the leveling of the second photoresist portion 022, resulting in a depression on the top of the second photoresist portion 022. Similarly, the third photoresist portion 023 is manufactured after the second photoresist portion 022, and the second photoresist portion 022 also has a large thickness after being manufactured, resulting in a depression on the top of the third photoresist portion 023. Due to the presence of the recess, the light emitted by the light-emitting device 011 located below the second light-blocking portion 022 will converge when passing through the second light-blocking portion 022, and the light emitted by the light-emitting device 011 located below the third light-blocking portion 023 will also converge when passing through the third light-blocking portion 023, which will cause display abnormalities such as uneven brightness and brightness attenuation on the display panel.

[0032] Based on this, some embodiments of the present application provide a display panel, such as Figures 2 to 4 As shown, the display panel 100 includes a driving substrate 10, a plurality of light emitting units 201 disposed on the driving substrate 10, an encapsulation layer 30 covering the plurality of light emitting units 201, and a plurality of light blocking units 401 disposed on the encapsulation layer 30. The number of the light emitting units 201 and the number of the light blocking units 401 may be the same.

[0033] Each light-emitting unit 201 includes a plurality of light-emitting devices 21 emitting light of different colors, each light-blocking unit 401 includes a plurality of light-blocking portions 41 allowing light of different colors to be emitted, and each light-blocking portion 41 covers a light-emitting device 21 emitting light of a corresponding color. As an example, each light-emitting unit 201 includes: a red light-emitting device emitting red light, a green light-emitting device emitting green light, and a blue light-emitting device emitting blue light, and each light-blocking unit 401 includes: a red light-blocking portion allowing red light to be emitted, a green light-blocking portion allowing green light to be emitted, and a blue light-blocking portion allowing blue light to be emitted, wherein the red light-blocking portion covers the red light-emitting device, the green light-blocking portion covers the green light-emitting device, and the blue light-blocking portion covers the blue light-emitting device, so that color display of the display panel 100 can be achieved.

[0034] In this embodiment, the light blocking unit 401 further includes at least one flat portion 42 disposed on the encapsulation layer 30 . In the light blocking unit 401 , one of the light blocking portions 41 contacts the encapsulation layer 30 , and at least one of the light blocking portions 41 is disposed on the flat portion 42 .

[0035] In this case, the light blocking portion 41 in contact with the encapsulation layer 30 (hereinafter referred to as the first light blocking portion for ease of description) can be made before other light blocking portions 41 (i.e., light blocking portions other than the first light blocking portion in the light blocking unit 401), so the first light blocking portion will not be affected by other light blocking portions during the manufacturing process, thereby ensuring that the first light blocking portion can be smoothly leveled. As for the light blocking portion 41 (hereinafter referred to as the selected light blocking portion for ease of description) disposed on the flat portion 42 among other light blocking portions, the flat portion 42 below it can reduce the step difference between the top of the surrounding elements of the selected light blocking portion (such as the first light blocking portion) and the bottom of the selected light blocking portion, thereby reducing the adverse effect of the surrounding elements of the selected light blocking portion on the leveling property during the manufacturing process of the selected light blocking portion, thereby improving the leveling degree of the selected light blocking portion to ensure the display effect of the display panel.

[0036] In some embodiments, Figures 2 to 4 As shown, the light blocking unit 401 includes a first light blocking portion 411, a second light blocking portion 412 and a third light blocking portion 413, and two flat portions 42 are provided. In the light blocking unit 401, the first light blocking portion 411 contacts the encapsulation layer 30, and the second light blocking portion 412 and the third light blocking portion 413 correspond to one flat portion 42 and are arranged on the corresponding flat portion 42.

[0037] In this case, the second light resist portion 412 and the third light resist portion 413 are both used as selected light resist portions, so that the step difference between the top of the surrounding elements of the selected light resist portion (for example, the first light resist portion 411) and the bottom of the selected light resist portion can be reduced through the corresponding flat portion 42, thereby reducing the adverse effects of the surrounding elements of the selected light resist portion on the leveling during the manufacturing process of the selected light resist portion, thereby improving the leveling degree of the selected light resist portion.

[0038] In some examples, the light-emitting unit 201 includes a first light-emitting device 211, a second light-emitting device 212 and a third light-emitting device 213, the first light-emitting device 211 is located below the first light-blocking portion 411, the second light-emitting device 212 is located below the second light-blocking portion 412, and the third light-emitting device 213 is located below the third light-blocking portion 413.

[0039] In some examples, the first light blocking portion 411 is one of a red light blocking portion, a green light blocking portion, and a blue light blocking portion, and the second light blocking portion 412 and the third light blocking portion 413 are the other two. For example, the first light blocking portion 411 is a blue light blocking portion, the second light blocking portion 412 is a red light blocking portion, and the third light blocking portion 413 is a green light blocking portion. In this case, the first light emitting device 211 is a blue light emitting device, the second light emitting device 212 is a red light emitting device, and the third light emitting device 213 is a green light emitting device.

[0040] In some embodiments, Figure 2 As shown, the light blocking unit 401 includes a first flat portion 421 located below the second light blocking portion 412 , that is, the flat portion 42 below the second light blocking portion 412 is the first flat portion 421 . The first flat portion 421 is adjacent to the first light blocking portion 411 .

[0041] In some examples, the thickness D1 of the first flat portion 421 is less than or equal to the thickness D2 of the first light blocking portion 411. In this way, the step difference between the top of the first light blocking portion 411 and the bottom of the second light blocking portion 412 can be reduced by the first flat portion 421, thereby reducing the adverse effect of the first light blocking portion 411 on the leveling property during the manufacturing process of the second light blocking portion 412, thereby improving the leveling degree of the second light blocking portion 412.

[0042] As an example, the thickness D1 of the first flat portion 421 is equal to the thickness D2 of the first light blocking portion 411, so that there is no step difference between the top of the first light blocking portion 411 and the bottom of the second light blocking portion 412, thereby eliminating the adverse effect of the first light blocking portion 411 on the leveling of the second light blocking portion 412 during the manufacturing process, and further ensuring that the second light blocking portion 412 has a good leveling degree, so as to facilitate the effective emission of light from the second light-emitting device 212 below.

[0043] As another example, Figure 3As shown, the thickness D1 of the first flat portion 421 is less than the thickness D2 of the first light blocking portion 411. In the case where the first flat portion 421 is manufactured before the first light blocking portion 411, the first light blocking portion 411 can cover part of the first flat portion 421, so that the second light blocking portion 412 manufactured later has an overlapping portion with the first light blocking portion 411, so as to block the light through the overlapping portion, thereby improving the display effect of the display panel 100.

[0044] In some examples, the thickness D2 of the first light blocking portion 411 is greater than or equal to 2 micrometers and less than or equal to 3 micrometers. For example, the thickness D2 of the first light blocking portion 411 is 3 micrometers.

[0045] In some examples, the thickness D1 of the first flat portion 421 may be greater than or equal to 2 micrometers and less than or equal to 3 micrometers. For example, the thickness D1 of the first flat portion 421 is 3 micrometers.

[0046] In some embodiments, Figure 2 As shown, the second light blocking portion 412 is partially located on the first light blocking portion 411. In this case, there is an overlapping portion between the second light blocking portion 412 and the first light blocking portion 411. Since the second light blocking portion 412 and the first light blocking portion 411 each only allow light of one color to be emitted, when the two have an overlapping portion, the overlapping portion can block the light. Therefore, the overlapping portion between the second light blocking portion 412 and the first light blocking portion 411 can block the light, thereby avoiding the problem of light crosstalk in adjacent areas (the light emitting area of ​​the first light emitting device 211 and the light emitting area of ​​the second light emitting device 212 adjacent thereto), thereby improving the display effect of the display panel 100.

[0047] It is worth noting that when there is an overlapping portion between the two light-blocking portions 41 (for example, there is an overlapping portion between the second light-blocking portion 412 and the first light-blocking portion 411), the adverse effect of the light-blocking portion 41 manufactured earlier on the leveling property of the light-blocking portion 41 manufactured later is further increased. Since the light-blocking portion 41 manufactured later is located on the flat portion 42, the step difference between the top of the light-blocking portion 41 manufactured earlier and the bottom of the light-blocking portion 41 manufactured later can be effectively reduced, thereby effectively alleviating the above-mentioned adverse effect, so as to ensure that the light-blocking portion 41 manufactured later can be smoothly leveled. In addition, the existence of the flat portion 42 also enables the light-blocking portion 41 manufactured later to have a relatively small thickness, so that the light-blocking portion 41 manufactured later can have an overlapping portion with the light-blocking portion 41 manufactured earlier. Since the light-blocking portion 41 manufactured later has a relatively small thickness, this is beneficial to the leveling property of the light-blocking portion 41 manufactured later, so as to further ensure that the top of the light-blocking portion 41 manufactured later does not have a depression.

[0048] In some embodiments, Figure 2As shown, the light blocking unit 401 further includes a second flat portion 422 located below the third light blocking portion 413, that is, the flat portion 42 below the third light blocking portion 413 is the second flat portion 422. The second flat portion 422 is adjacent to the first flat portion 421.

[0049] In some examples, the thickness D4 of the second flat portion 422 is greater than the thickness D1 of the first flat portion 421. In this way, the step difference between the top of the second light blocking portion 412 and the bottom of the third light blocking portion 413 can be reduced by the second flat portion 422, thereby reducing the adverse effect of the second light blocking portion 412 on the leveling property during the manufacturing process of the third light blocking portion 413, thereby improving the leveling degree of the third light blocking portion 413.

[0050] In some embodiments, Figure 2 As shown, the thickness D4 of the second flat portion 422 is equal to the sum of the thickness D1 of the first flat portion 421 and the thickness D3 of the second light blocking portion 412 .

[0051] Such an arrangement can ensure that there is no step difference between the top of the second light blocking portion 412 and the bottom of the third light blocking portion 413, thereby eliminating the adverse effect of the second light blocking portion 412 on the leveling during the manufacturing process of the third light blocking portion 413, and further ensuring that the third light blocking portion 413 has a good leveling degree, so as to facilitate the effective emission of light from the third light-emitting device 213 below.

[0052] In some examples, the thickness D3 of the second light blocking portion 412 is greater than or equal to 2 micrometers and less than or equal to 3 micrometers. For example, the thickness D3 of the second light blocking portion 412 may be equal to the thickness D2 of the first light blocking portion 411 .

[0053] In some examples, the thickness D4 of the second flat portion 422 is greater than or equal to 4 micrometers and less than or equal to 6 micrometers. For example, when the thickness D3 of the second light blocking portion 412 and the thickness D1 of the first flat portion 421 are both 3 micrometers, the thickness D4 of the second flat portion 422 may be 6 micrometers.

[0054] In some examples, along the thickness direction of the display panel 100 , the first flat portion 421 covers the second light emitting device 212 , and the second flat portion 422 covers the third light emitting device 213 .

[0055] It is worth noting that the flat portion 42 has a high light transmittance to reduce or avoid the flat portion 42 affecting the light emission of the light emitting device 21 located thereunder. As an example, the flat portion 42 may be made of an organic photoresist such as an OC photoresist. As another example, the flat portion 42 may be made of an inorganic material such as silicon oxide or silicon nitride.

[0056] In some embodiments, Figures 2 to 4As shown, the third light blocking portion 413 is partially located on the second light blocking portion 412. In this case, there is an overlapping portion between the third light blocking portion 413 and the second light blocking portion 412, and the overlapping portion can block the light, thereby avoiding the problem of light crosstalk in adjacent areas (the light emitting area of ​​the second light emitting device 212 and the light emitting area of ​​the third light emitting device 213 adjacent thereto), thereby improving the display effect of the display panel 100.

[0057] In some embodiments, Figures 2 to 4 As shown, there is a gap between the second flat portion 422 and the first flat portion 421, and the light blocking unit 401 also includes at least one first auxiliary light blocker 43, the first auxiliary light blocker 43 and the first light blocking portion 411 allow light of the same color to be emitted, a first auxiliary light blocker 43 is arranged in the gap, and the second light blocking portion 412 covers the first auxiliary light blocker 43.

[0058] In this case, there is an overlapping portion between the second light resistance portion 412 and the first auxiliary light resistance portion 43, which can avoid the problem of light crosstalk between the light emitting area of ​​the second light emitting device 212 and the light emitting area of ​​the adjacent third light emitting device 213, thereby improving the display effect of the display panel 100.

[0059] In some examples, along the thickness direction of the display panel 100, the second light blocking portion 412, the third light blocking portion 413 and the first auxiliary light blocking portion 43 have an overlapping portion, so as to ensure that the overlapping portion has a good shading effect, thereby avoiding the problem of light crosstalk between the light emitting area of ​​the second light emitting device 212 and the light emitting area of ​​the adjacent third light emitting device 213, thereby improving the display effect of the display panel 100.

[0060] In some embodiments, Figures 2 to 4 As shown, the light blocking unit 401 further includes at least one third auxiliary light blocking unit 45, and the third auxiliary light blocking unit 45 and the third light blocking unit 413 allow light of the same color to be emitted. Along the thickness direction of the display panel 100, a third auxiliary light blocking unit 45, the second light blocking unit 412, and the first light blocking unit 411 have an overlapping portion. In this way, it can be ensured that the overlapping portion has a good light shielding effect, thereby avoiding the problem of light crosstalk between the light emitting area of ​​the first light emitting device 211 and the light emitting area of ​​the second light emitting device 212 adjacent thereto, thereby improving the display effect of the display panel 100.

[0061] In some embodiments, Figures 2 to 4As shown, the light blocking unit 401 also includes at least one second auxiliary light blocking 44, and the second auxiliary light blocking 44 and the second light blocking portion 412 allow light of the same color to be emitted. A first auxiliary light blocking 43 and a second auxiliary light blocking 44 are provided on the side of the second flat portion 422 away from the first flat portion 421, and the second auxiliary light blocking 44 covers the first auxiliary light blocking 43, and along the thickness direction of the display panel 100, the third light blocking portion 413, the second auxiliary light blocking 44 and the first auxiliary light blocking 43 have overlapping parts, so that the overlapping parts can be ensured to have a good light shielding effect, thereby avoiding the problem of light crosstalk between the light emitting area of ​​the third light emitting device 213 and the light emitting area of ​​the light emitting device located on the right side of the third light emitting device 213, thereby improving the display effect of the display panel 100. It is worth noting that the third light emitting device 213 is located between the light emitting device on the right side of the third light emitting device 213 and the second light emitting device 212 on the left side of the third light emitting device 213.

[0062] In some embodiments, a second auxiliary light blocker 44 is provided on the surface of the first light blocker 411 away from the first flat portion 421, and a third auxiliary light blocker 45 is provided on the second auxiliary light blocker 44. Along the thickness direction of the display panel 100, the first light blocker 411, the second auxiliary light blocker 44 and the third auxiliary light blocker 45 have overlapping parts, so that the overlapping parts can be ensured to have a good light shielding effect, thereby avoiding the problem of light crosstalk between the light emitting area of ​​the first light emitting device 211 and the light emitting area of ​​the light emitting device located on the left side of the first light emitting device 211, thereby improving the display effect of the display panel 100. It is worth noting that the first light emitting device 211 is located between the light emitting device on the left side of the first light emitting device 211 and the second light emitting device 212 on the right side of the first light emitting device 211.

[0063] In some embodiments, Figure 3 and Figure 4 As shown, the display panel 100 further includes a color filter layer 40, a light blocking unit 401 is located in the color filter layer 40, and a plurality of touch lines 51 are arranged between the encapsulation layer 30 and the color filter layer 40. The touch lines 51 are arranged in the touch layer 50.

[0064] The touch function of the display panel 100 is realized.

[0065] In this embodiment, the light-emitting unit 201 is located in the light-emitting device layer 20 , and the orthographic projection of each touch-control trace 51 on the light-emitting device layer 20 is located between two adjacent light-emitting devices 21 .

[0066] By arranging the touch line 51 between two adjacent light emitting devices 21 , it is possible to avoid the touch line 51 blocking the light in the direction facing the light emitting devices 21 , thereby ensuring that the display panel 100 has a good display effect.

[0067] In some examples, an interlayer insulating layer 60 is disposed on a side of the encapsulation layer 30 away from the driving substrate 10 , and the touch control layer 50 is disposed on the interlayer insulating layer 60 .

[0068] In some examples, the display panel 100 further includes a flat film 70 located on the color filter layer 40 . The flat film 70 can be used to flatten all the light blocking units 401 in the color filter layer 40 to facilitate the layout of the upper layers.

[0069] In some embodiments, Figure 3 and Figure 4 As shown, the light blocking portion 41 (eg, the first light blocking portion 411 ) in contact with the encapsulation layer 30 covers at least one touch wiring 51 .

[0070] In some examples, the thickness of the touch trace 51 is greater than or equal to 0.3 micrometers and less than or equal to 0.7 micrometers. For example, the thickness of the touch trace 51 is 0.5 micrometers.

[0071] Since the touch wiring 51 has a relatively small thickness, it has a small effect on the leveling property of the light blocking portion 41, so the first light blocking portion 411 can be smoothly leveled. In this case, the color filter layer 40 can be directly manufactured on the touch wiring 51, so that the material layout between the touch wiring 51 and the color filter layer 40 can be omitted, thereby reducing the thickness of the display panel 100.

[0072] In some embodiments, Figure 3 and Figure 4 As shown, along the thickness direction of the display panel 100, each light blocking portion 41 covers two touch control traces 51, and the orthographic projections of the two touch control traces 51 on the light emitting device layer 20 are located on both sides of the light emitting device 21 below the light blocking portion 41. For example, the second light blocking portion 412 covers the two touch control traces 51, and the orthographic projections of the two touch control traces 51 on the light emitting device layer 20 are located on both sides of the light emitting device 21 below the second light blocking portion 412.

[0073] Such an arrangement enables each light blocking portion 41 to have a relatively large area, which is conducive to forming an overlapping portion between the light blocking portion 41 and the light blocking portion or auxiliary light blocking portion that allows other color light to be emitted, so that the area above the touch wiring 51 has a good shading effect, thereby improving the display effect of the display panel 100.

[0074] In some examples, along the thickness direction of the display panel 100, the third light resist 413, the second auxiliary light resist 44 and the first auxiliary light resist 43 have an overlapping portion, and the overlapping portion at least partially covers a touch line 51. In this way, the area above the touch line 51 can have a good light shielding effect, thereby improving the display effect of the display panel 100. As an example, the overlapping portion completely covers the touch line 51.

[0075] In some examples, along the thickness direction of the display panel 100, the third light blocking portion 413, the second light blocking portion 412, and the first auxiliary light blocking portion 43 have an overlapping portion, and the overlapping portion at least partially covers a touch line 51. In this way, the area above the touch line 51 can have a good light shielding effect, thereby improving the display effect of the display panel 100. As an example, the overlapping portion completely covers the touch line 51.

[0076] In some examples, along the thickness direction of the display panel 100, the third auxiliary light resist 45, the second light resist portion 412 and the first light resist portion 411 have an overlapping portion, and the overlapping portion at least partially covers a touch line 51. In this way, the area above the touch line 51 can have a good light shielding effect, thereby improving the display effect of the display panel 100. As an example, the overlapping portion completely covers the touch line 51.

[0077] In some examples, along the thickness direction of the display panel 100, the first light resist 411, the second auxiliary light resist 44, and the third auxiliary light resist 45 have an overlapping portion, and the overlapping portion at least partially covers a touch line 51. In this way, the area above the touch line 51 can have a good light shielding effect, thereby improving the display effect of the display panel 100. As an example, the overlapping portion completely covers the touch line 51.

[0078] Some embodiments of the present application also provide a display device, such as Figure 5 As shown, the display device 200 includes the display panel 100 described in any one of the above embodiments.

[0079] Since the display device 200 includes the display panel 100 , the display device 200 has the technical effects of the display panel 100 , which will not be described in detail here.

[0080] In some examples, the display device 200 further includes a mounting frame 202 , through which the display panel 100 can be fixed and mounted to facilitate the use of the display device 200 .
