Summary of the Invention

Problems to be Solved by the Invention

[0005] In view of at least one of the above technical problems, embodiments of this application provide a display panel and a display device, and can simplify the manufacturing process of the display panel and the display device.

Means for Solving the Problems

[0006] In order to achieve the above object, embodiments of this application provide the following technical solutions.

[0007] In the first aspect, an embodiment of the present application provides a display panel including a light-emitting area and a non-light-emitting area. The display panel includes a light-emitting side and a light-opposite side that are provided to face each other along the thickness direction. The display panel includes a touch layer and a light filter layer. The light filter layer includes a light-shielding layer and a color resist. The color resist is located in the touch layer and at least partially within the light-emitting area. The light-shielding layer is on the side close to the light-emitting side of the touch layer and within the non-light-emitting area.

[0008] Regarding the display panel provided by the embodiment of the present application, the display panel can include a light-emitting area and a non-light-emitting area, and the light-emitting area and the non-light-emitting area can be provided adjacent to each other. The display panel includes a light-emitting side and a light-opposite side that are provided to face each other along the thickness direction. The display panel includes a touch layer and a light filter layer. The light filter layer is used to improve the display effect of the display panel by suppressing the reflection of ambient light. The light filter layer includes a light-shielding layer and a color resist. The color resist is in the touch layer and at least partially within the light-emitting area. The structural layer (e.g., the first insulating layer and / or the second insulating layer) in the touch layer can prevent water and oxygen from eroding the color resist and form a protection for the color resist, so there is no need to separately provide a blocking layer for the color resist, and the manufacturing processes of the display panel and the display device can be simplified. The light-shielding layer is on the side close to the light-emitting side of the touch layer and within the non-light-emitting area. Since the light-shielding layer can absorb the light irradiated on it, the reflected light from the environment can be reduced.

[0009] In one possible implementation, the touch layer includes a first touch wiring and a second touch wiring located on the side close to the light-emitting side of the first touch wiring.

[0010] It is possible that the orthographic projection of the light-shielding layer on the plane where the first touch wiring is arranged covers the first touch wiring, and / or the orthographic projection of the light-shielding layer on the plane where the second touch wiring is arranged covers the second touch wiring.

[0011] As a feasible solution, the color resist extends at least partially to the non-emitting area, and the orthographic projection of the color resist located in the non-emitting area within the plane where the light-shielding layer is disposed overlaps at least partially with the light-shielding layer.

[0012] In this way, the light-shielding layer can effectively prevent the reflection of ambient light and ensure the display effect of the display panel and the display device.

[0013] In one possible implementation, the color resist includes a first color resist provided on the same layer as the first touch wiring.

[0014] As a feasible solution, the surface of the first color resist close to the light-emitting side is flush with the surface of the first touch wiring close to the light-emitting side or protrudes from the surface of the first touch wiring close to the light-emitting side.

[0015] In this way, the first color resist can prevent the reflection of ambient light and ensure the display effect of the display panel and the display device.

[0016] In one possible implementation, a sealing layer is provided on the side of the touch layer opposite to the light-shielding layer and in contact with the first color resist.

[0017] In this way, it is beneficial for the weight reduction of the display panel.

[0018] In one possible implementation, a light-emitting layer is provided on the side of the sealing layer opposite to the light-shielding layer. The light-emitting layer includes an anode layer, a pixel layer, and a cathode layer that are stacked along the thickness direction. The anode layer is located on the side of the pixel layer opposite to the light-shielding layer, and the pixel layer is located in the light-emitting area.

[0019] The anode layer includes a plurality of anodes, and the pixel layer includes a plurality of pixels.

[0020] In one possible implementation, at least one of the anode and the pixel has a shape including a circle.

[0021] As a feasible solution, the light-emitting layer includes a pixel defining layer between the anode layer and the cathode layer. The pixel defining layer has a plurality of first openings, and the pixel is located in the first openings. The orthographic projection of the pixel defining layer on the plane where the anode is disposed covers the edge of the anode. The first openings are shaped to include a circular shape, and / or the light-shielding layer has a plurality of second openings. The orthographic projection of the second openings on the light-emitting layer covers the pixel layer, and the second openings are shaped to include a circular shape.

[0022] In one possible implementation, the color resist includes a second color resist provided on the same layer as the second touch wiring.

[0023] As a feasible solution, the surface of the second color resist closer to the light-emitting side is flush with the surface of the second touch wiring closer to the light-emitting side or protrudes from the surface of the second touch wiring closer to the light-emitting side.

[0024] In this way, the second color resist can prevent the reflection of ambient light and ensure the display effect of the display panel and the display device.

[0025] In one possible implementation, the touch layer further includes an auxiliary color resist located in a different layer. The auxiliary color resist located in a different layer is provided in a layer different from the first touch wiring and is provided in a layer different from the second touch wiring.

[0026] The auxiliary color resist located in a different layer is located on at least one of the surface of the first touch wiring closer to the light-emitting side and the surface of the first touch wiring closer to the light-reverse side, and / or the auxiliary color resist located in a different layer is located on at least one of the surface of the second touch wiring closer to the light-emitting side and the surface of the second touch wiring closer to the light-reverse side.

[0027] In this way, the auxiliary color resist located in a different layer can form protection for the first touch wiring and / or the second touch wiring.

[0028] In one possible implementation, it further includes a side auxiliary color resist located on the touch layer. The side auxiliary color resist is located on the side close to the light-emitting area of the non-light-emitting area, and the color of the side auxiliary color resist is different from that of the adjacent color resist.

[0029] In one possible implementation, it includes a display area and a non-display area, and both the light-emitting area and the non-light-emitting area are located in the display area.

[0030] The light-shielding layer includes a first light-shielding layer located in the display area and a second light-shielding layer located in the non-display area.

[0031] In this way, the second light-shielding layer is beneficial to the sealing performance of the display panel.

[0032] In the second aspect, the embodiment of the present application provides a display device including the display panel in the above first aspect.

Advantages of the Invention

[0033] Regarding the display device provided by the embodiments of the present application, the display device can include a display panel that can include a light-emitting area and a non-light-emitting area, and the light-emitting area and the non-light-emitting area can be provided adjacent to each other. The display panel includes a light-emitting side and a light-opposite side that are provided to face each other along the thickness direction. The display panel includes a touch layer and a light filter layer. The light filter layer is used to improve the display effect of the display panel by suppressing the reflection of ambient light. The light filter layer includes a light-shielding layer and a color resist. The color resist is in the touch layer and at least partially within the light-emitting area. The structural layer in the touch layer (for example, the above-mentioned first insulating layer and / or the second insulating layer) can prevent water and oxygen from eroding the color resist and form a protection for the color resist, so there is no need to separately provide a blocking layer for the color resist, and the manufacturing processes of the display panel and the display device can be simplified. The light-shielding layer is on the side close to the light-emitting side of the touch layer and within the non-light-emitting area. Since the light-shielding layer can absorb the light irradiated on the light-shielding layer, the reflected light from the environment can be reduced.

Modes for Carrying Out the Invention

[0036] In the related art, a display panel includes a light-emitting area and a non-light-emitting area adjacent to the light-emitting area. The display panel includes a touch layer and an optical filter layer on the touch layer. The optical filter layer includes a color resist layer located in the light-emitting area and a light-shielding layer located in the non-light-emitting area. The touch layer includes a first touch wiring, a first insulating layer, a second touch wiring, and a second insulating layer provided in a sequential stacked manner. Both the first touch wiring and the second touch wiring are located in the non-light-emitting area, and both the first insulating layer and the second insulating layer are located in the light-emitting area and the non-light-emitting area.

[0037] However, since the color resist layer is formed of an organic material and is easily eroded by water and oxygen, it is necessary to provide a blocking layer on the side opposite to the touch layer of the color resist layer to form protection for the color resist layer and avoid water and oxygen from eroding the color resist layer. As a result, the manufacturing processes of the display panel and the display device become complicated.

[0038] In view of at least one of the above technical problems, embodiments of the present application provide a display panel and a display device. The display panel can include a light-emitting area and a non-light-emitting area, and the light-emitting area and the non-light-emitting area can be provided adjacent to each other. The display panel includes a light-emitting side and a light-back side provided to face each other along the thickness direction. The display panel includes a touch layer and a light filter layer. The light filter layer is used to improve the display effect of the display panel by suppressing the reflection of ambient light. The light filter layer includes a light-shielding layer and a color resist. The color resist is in the touch layer and at least partially within the light-emitting area. The structural layer (for example, the above-mentioned first insulating layer and / or the second insulating layer) in the touch layer can prevent water and oxygen from eroding the color resist and form protection for the color resist, so that it is not necessary to separately provide a blocking layer for the color resist, and the manufacturing processes of the display panel and the display device can be simplified. The light-shielding layer is on the side close to the light-emitting side of the touch layer and within the non-light-emitting area. Since the light-shielding layer can absorb the light irradiated on the light-shielding layer, the reflected light of the environment can be reduced.

[0039] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, hereinafter, with reference to the drawings related to the embodiments of the present application, the technical solutions will be described clearly and completely. It goes without saying that the described embodiments are only a part of the embodiments of the present application, not all of them. Those skilled in the art can obtain all other embodiments without creative labor based on the embodiments in the present application, and all of them belong to the protection scope of the present application.

[0040] Hereinafter, the display device provided by the embodiments of the present application will be described with reference to FIGS. 1 to 11.

[0041] This embodiment provides a display device including a display panel 100. The display device may be a mobile or fixed terminal having a display panel 100 such as an electronic paper, a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, a smart bracelet, a smart watch, a super personal computer, a navigator, etc.

[0042] The display panel 100 may be an Organic Light-Emitting Diode (abbreviated as OLED) display panel, a Micro Light Emitting Diode (abbreviated as Micro LED or μLED) display panel, or a Liquid Crystal Display (abbreviated as LCD) display panel.

[0043] The embodiments of the present application will be described by taking the case where the display panel 100 is an OLED display panel as an example.

[0044] Hereinafter, the display panel 100 provided by the embodiments of the present application will be described.

[0045] This embodiment provides a display panel 100 applicable to the above display device.

[0046] The display panel 100 can include a light-emitting side and a light-opposing side provided to face each other along the thickness direction. The light-emitting side is the side used for screen display, and the light-opposing side is the other side provided to oppose the light-emitting side along the thickness direction of the display panel 100.

[0047] As shown in FIG. 1, the display panel 100 can include an array substrate 110 and a light-emitting layer 120 located on the array substrate 110. The array substrate 110 is provided with a plurality of driving units that can be arranged in an array and are electrically connected to the light-emitting layer 120, and the driving units are used to provide a driving current to the light-emitting layer 120. The driving unit can include a thin film transistor (abbreviated as TFT) and a capacitor structure. For example, the thin film transistor can include at least one of a metal oxide (abbreviated as MO) thin film transistor and a low temperature poly-silicon (abbreviated as LTPS) thin film transistor.

[0048] Hereinafter, the light-emitting layer 120 provided by the embodiments of the present application will be described.

[0049] The light-emitting layer 120 can include a cathode layer and an anode layer located on the side of the cathode layer facing the array substrate 110. The anode layer may be a pixel electrode, and the cathode layer may be a common electrode. Here, the anode layer can include a plurality of anodes that are provided at intervals and can have a circular shape. Naturally, the anode can also be any one or more of shapes such as an ellipse, a polygon (a quadrilateral, a pentagon, a hexagon, etc.). Because of the many options, there are many applicable scenarios.

[0050] As shown in FIG. 1, the light-emitting layer 120 can include a pixel layer 121 and a pixel confinement layer 122. The pixel layer 121 is formed of a light-emitting material, and the pixel layer 121 and the pixel confinement layer 122 are located between the anode layer and the cathode layer. The pixel layer 121 can generally include a plurality of pixels that can be arranged in an array. The plurality of pixels can include, but are not limited to, red pixels, green pixels, and blue pixels. In some other examples, the plurality of pixels may further include white pixels. The pixel confinement layer 122 is located between two adjacent pixels, and the pixel confinement layer 122 can be provided so as to surround the outer periphery of the pixel. For example, the pixel can be circular in shape. Of course, the pixel can be any one or more of shapes such as elliptical, polygonal (quadrilateral, pentagon, hexagon, etc.). Because there are many options, there are many applicable scenarios.

[0051] As shown in FIG. 1, the pixel confinement layer 122 has a plurality of first openings 181 provided at intervals. The first openings 181 are used for the arrangement of pixels that can be deposited in the first openings 181. The orthographic projection of the pixel confinement layer 122 on the plane where the anode is arranged covers the edge of the anode. For example, the first opening 181 can be circular in shape. Of course, the first opening 181 can also be any one or more of shapes such as elliptical, polygonal (quadrilateral, pentagon, hexagon, etc.). Because there are many options, there are many applicable scenarios.

[0052] The light-emitting layer 120 can further include at least one of a hole injection layer, a hole transport layer, an electron barrier layer, a hole barrier layer, an electron transport layer, and an electron injection layer.

[0053] As shown in FIG. 1, it can be understood that the display panel 100 can include a display area 100a used for screen display and a non-display area 100b provided adjacent to the display area 100a. The non-display area 100b is located on at least one side of the display area 100a. For example, the non-display area 100b can be provided so as to surround the outer periphery of the display area 100a.

[0054] As shown in FIG. 2, the display area 100a can include a light-emitting area 100c corresponding to the pixels located within the light-emitting area 100c and a non-light-emitting area 100d. For example, the light-emitting area 100c can overlap with the pixels, and a non-light-emitting area 100d can be provided between adjacent light-emitting areas 100c so as to surround the outer periphery of the light-emitting area 100c. The non-light-emitting area 100d can correspond to at least a part of the pixel confinement layer 122.

[0055] As shown in FIG. 1, the display panel 100 can further include a sealing layer 130 located on the side opposite to the array substrate 110 of the light-emitting layer 120. The sealing layer 130 is used to seal the light-emitting layer 120 to prevent external water and oxygen from penetrating into the light-emitting layer 120 and the driving unit and damaging the display panel 100.

[0056] Exemplarily, the sealing layer 130 can adopt a thin film encapsulation technology (abbreviated as Thin Film Encapsulation, TFE). The TFE sealing layer can include a plurality of sealing sub-film layers, and the TFE can adopt a multi-layer stacked structure in which an inorganic layer / an organic layer / an inorganic layer are stacked. Here, the inorganic layer is used to effectively block water and oxygen, and the organic layer is used to buffer the stress in the inorganic layer.

[0057] As shown in FIG. 1, the display panel 100 can further include a touch layer 140 located on the side opposite to the array substrate 110 of the sealing layer 130 to realize a touch function.

[0058] Exemplarily, a buffer layer formed of an inorganic material (for example, silicon nitride, silicon oxide, etc.) or an organic material can be provided between the touch layer 140 and the sealing layer 130. Of course, the touch layer 140 can be directly provided on the sealing layer 130 without providing a buffer layer, which is advantageous for reducing the weight of the display panel 100. The embodiments of the present application will be described by taking the case where the touch layer 140 is in direct contact with the sealing layer 130 as an example.

[0059] Hereinafter, the touch layer 140 provided by the embodiments of the present application will be described.

[0060] As shown in FIG. 2, the touch layer 140 can include a first touch wiring 141 and a second touch wiring 142. The second touch wiring 142 is located on the side closer to the light-emitting side of the first touch wiring 141. That is, the second touch wiring 142 is located on the side opposite to the light-emitting layer 120 of the first touch wiring 141.

[0061] In the touch layer 140, one of the first touch wiring 141 and the second touch wiring 142 may be a crosslinking layer, and the other of the first touch wiring 141 and the second touch wiring 142 may be a touch functional layer. The touch functional layer can include a plurality of first touch electrodes extending along a first direction and a plurality of second touch electrodes extending along a second direction. Here, the first direction and the second direction are different. For example, the first direction may be the length direction of the display panel 100, and the second direction may be the width direction of the display panel 100.

[0062] The length, width, and thickness described in the embodiments of the present application are for the convenience of description only and do not imply any limitation on the dimensions. For example, the length can be greater than, equal to, or smaller than the width.

[0063] Exemplarily, one of the first touch electrode and the second touch electrode is a driving electrode, and the other of the first touch electrode and the second touch electrode is a sensing electrode. Note that both the driving electrode and the sensing electrode are formed from the second touch wiring 142 but are insulated from each other. One of the driving electrode and the sensing electrode has a structure that is continuously unbroken along the first direction (or the second direction), and the other of the driving electrode and the sensing electrode includes a plurality of sub-structures arranged at intervals along the second direction (or the first direction) and is crosslinked by a crosslinking layer.

[0064] Exemplarily, both the first touch wiring 141 and the second touch wiring 142 can be located in the non-light-emitting area 100d, and as a result, the influence on the aperture ratio of the display panel 100 can be avoided.

[0065] Exemplarily, the first touch wiring 141 and the second touch wiring 142 may be formed of a single-layer conductive layer or may have a laminated structure of a multi-layer conductive layer.

[0066] In some embodiments, as shown in FIG. 2, the touch layer 140 can include a first insulating layer 143, which is located between the first touch wiring 141 and the second touch wiring 142 and is used to electrically isolate the first touch wiring 141 and the second touch wiring 142. Further, the touch layer 140 can further include a second insulating layer 144, which can be located on the side opposite to the light-emitting layer 120 of the second touch wiring 142 and can protect the first touch wiring 141 and the second touch wiring 142.

[0067] The display panel 100 can include an optical filter layer, and the optical filter layer can be used to suppress the reflection of ambient light and improve the display effect of the display panel 100.

[0068] Hereinafter, the optical filter layer provided by the embodiments of the present application will be described.

[0069] The optical filter layer can include a color resist that can be used to filter light of a color different from itself in ambient light. The color resist can be formed of an organic material, has high flexibility, and is advantageous for the bending performance of the display panel 100.

[0070] The color resist can be integrated into the touch layer 140, and the structural layers in the touch layer 140, such as the first insulating layer 143 and / or the second insulating layer 144, can form protection for the color resist, so that it is not necessary to separately provide a blocking layer for the color resist, thereby simplifying the manufacturing process of the display panel 100 and the display device.

[0071] The distance between the color resist and the light-emitting layer 120 can affect the light filtering effect on the light of the corresponding color by the color resist. If the distance along the thickness direction between the color resist and the light-emitting layer 120 is too large, the light emitted by the pixel will be more likely to diffuse outward, resulting in a decrease in the amount of light emitted from the color resist corresponding to the pixel. As a result, the display panel 100, the display viewing angle of the display device, and the display luminance will all be poor. When the color resist is integrated into the touch layer 140, the color resist is closer to the pixel, and the amount of light emitted from the color resist corresponding to the pixel increases, so that the display panel 100, the display viewing angle of the display device, and the display luminance can be improved.

[0072] Here, the color resist is at least partially located in the light-emitting area 100c. The color resist located in the same layer can include a plurality of sub-color resists provided to correspond to pixels one-to-one. To ensure that the orthographic projection of the sub-color resist on the light-emitting layer 120 covers the pixel and has the same color as the covered pixel, the occurrence of light mixing can be avoided. The plurality of sub-color resists can include any one or more of a red sub-color resist, a green sub-color resist, a blue sub-color resist, and a white sub-color resist. For example, the sub-color resist provided corresponding to a red pixel is a red sub-color resist, and the red sub-color resist can block the light emitted by blue and green pixels and allow the red light emitted by red or white pixels to pass through.

[0073] Since the size of the sub-color resist is greater than or equal to the size of the pixel, the orthographic projection of the sub-color resist on the light-emitting layer 120 can cover the pixel. In some examples, the orthographic projection of the sub-color resist on the light-emitting layer 120 can overlap with the pixel, and at this time, the sub-color resist has the same size as the pixel (for example, the first color resist 161 in FIG. 2). In some other examples, the orthographic projection of the sub-color resist on the light-emitting layer 120 can cover the pixel, and there is a gap between the outer edge of the orthographic projection of the sub-color resist on the light-emitting layer 120 and the outer edge of the pixel. At this time, since the sub-color resist is larger in size than the pixel, the amount of light emitted from the sub-color resist corresponding to the pixel increases (for example, the first color resist 161 in FIG. 3).

[0074] Here, the sub-color resist can be circular in shape. Naturally, the sub-color resist can be any one or more of shapes such as oval, polygon (quadrilateral, pentagon, hexagon, etc.). Because there are many options, there are many applicable scenarios.

[0075] As shown in FIG. 2, the color resist can include a first color resist 161 provided in the same layer as the first touch wiring 141. Here, the fact that the first color resist 161 is "provided in the same layer as" the first touch wiring 141 means that the first touch wiring 141 and the first color resist 161 are manufactured to be provided on the same side surface along the thickness direction in the same basic structure layer. For example, the first touch wiring 141 and the first color resist 161 are provided on the surface of the encapsulation layer 130 opposite to the light-emitting layer 120. Since the principle of the arrangement method provided in the same layer in the embodiments of the present application is similar, it will not be repeatedly described hereinafter.

[0076] Hereinafter, the first color resist 161 provided by the embodiments of the present application will be described.

[0077] The first color resist 161 includes a plurality of sub-color resists provided on the same layer. The sub-color resist may be the first sub-color resist, and since its principle has already been described, it will not be repeatedly described here.

[0078] Exemplarily, the first color resist 161 and the first touch wiring 141 can be directly manufactured in the encapsulation layer 130. At this time, both the first color resist 161 and the first touch wiring 141 are in contact with the encapsulation layer 130, and since the first color resist 161 is arranged to be close to the light-emitting layer 120, the display panel 100, the display viewing angle of the display device, and the display luminance can be well ensured.

[0079] Exemplarily, as shown in FIG. 3, since the surface of the first color resist 161 close to the light-emitting side is flush with the surface of the first touch wiring 141 close to the light-emitting side, the surfaces of the first color resist 161 and the first touch wiring 141 on the side opposite to the light-emitting layer are flat. Alternatively, as shown in FIG. 4, the surface of the first color resist 161 close to the light-emitting side may protrude from the surface of the first touch wiring 141 close to the light-emitting side, which is advantageous for preventing light mixing of adjacent pixels.

[0080] In some examples, as shown in FIGS. 2 to 4, since there is a gap between the first color resist 161 and the first touch wiring 141, it is possible to avoid mutual interference during the manufacturing of the first color resist 161 and the first touch wiring 141 caused by processing errors. In some other examples, as shown in FIG. 5, since the side wall surface of the first color resist 161 can be in contact with the side wall surface of the first touch wiring 141, the surfaces of the first color resist 161 and the first touch wiring 141 on the side opposite to the light-emitting layer 120 are complete. When the surface of the first color resist 161 on the side opposite to the light-emitting layer 120 is flush with the surface of the first touch wiring 141 on the side opposite to the light-emitting layer 120, a flat surface is provided. Also, since the first color resist 161 has a larger size, more light can pass through the first color resist 161, and the display panel 100, the display viewing angle of the display device, and the display luminance can be well ensured.

[0081] As shown in FIG. 2, the first insulating layer 143 can be located on the side opposite to the light-emitting layer 120 of the first touch wiring 141 and the first color resist 161. The first insulating layer 143 and other structural layers on the side opposite to the light-emitting layer 120 of the first insulating layer 143 can protect the first color resist 161, and there is no need to separately provide a blocking layer for the first color resist 161, so the manufacturing process of the display panel 100 and the display device can be simplified.

[0082] In some embodiments, as shown in FIG. 6, the color resist can include a second color resist 162 provided in the same layer as the second touch wiring 142. The second color resist 162 and the second touch wiring 142 can be located on the side opposite to the light-emitting layer 120 of the first insulating layer 143.

[0083] Hereinafter, the second color resist 162 provided by the embodiments of the present application will be described.

[0084] The second color resist 162 includes a plurality of sub-color resists provided on the same layer. The sub-color resist may be a second sub-color resist. Since its principle has already been described, it will not be repeatedly described here.

[0085] Exemplarily, the surface of the second color resist 162 close to the light-emitting side may be flush with the surface of the second touch wiring 142 close to the light-emitting side, or the surface of the second color resist 162 close to the light-emitting side may protrude from the surface of the second touch wiring 142 close to the light-emitting side. Since its principle is similar to the arrangement principle between the first color resist 161 and the first touch wiring 141, it will not be repeatedly described here.

[0086] Exemplarily, as shown in FIG. 6, there may be a gap between the second color resist 162 and the second touch wiring 142, or as shown in FIG. 7, the side wall surface of the second color resist 162 and the side wall surface of the second touch wiring 142 can be brought into contact with each other. Since its principle is similar to the arrangement principle between the first color resist 161 and the first touch wiring 141, it will not be repeatedly described here.

[0087] It should be noted that the first color resist 161 and the second color resist 162 may be provided individually or simultaneously.

[0088] In some embodiments, as shown in FIGS. 8 to 10, an interlayer auxiliary color resist 171 may be further provided on the touch layer 140. The interlayer auxiliary color resist 171 is provided in a layer different from the first touch wiring 141, and the interlayer auxiliary color resist 171 is provided in a layer different from the second touch wiring 142. The fact that the interlayer auxiliary color resist 171 is "provided in a layer different from" the first touch wiring 141 means that the interlayer auxiliary color resist 171 is provided by being laminated with the first touch wiring 141 in the thickness direction. Here, the interlayer auxiliary color resist 171 can be in contact with the first touch wiring 141 or provided at an interval along the thickness direction. The fact that the interlayer auxiliary color resist 171 is "provided in a layer different from" the second touch wiring 142 means that the interlayer auxiliary color resist 171 is provided by being laminated with the second touch wiring 142 in the thickness direction. Here, the interlayer auxiliary color resist 171 can be in contact with the second touch wiring 142 or provided at an interval along the thickness direction. Since the arrangement methods in different layers in the embodiments of the present application are similar in principle, they will not be repeatedly described hereinafter.

[0089] Exemplarily, as shown in FIGS. 8 and 9, the interlayer auxiliary color resist 171 can be located on the surface of the first touch wiring 141 opposite to the light-emitting layer 120. When the first color resist 161 is also provided at the same time, the interlayer auxiliary color resist 171 may be located on the surface of the first color resist 161 opposite to the light-emitting layer 120, that is, the interlayer auxiliary color resist 171 can simultaneously cover the surfaces of the first touch wiring 141 and the first color resist 161 opposite to the light-emitting layer 120. For example, the surface of the interlayer auxiliary color resist 171 opposite to the light-emitting layer 120 can be made flush, and as a result, a flat support surface can be provided for the structural layer manufactured thereon later. Alternatively, the surface of the interlayer auxiliary color resist 171 opposite to the light-emitting layer 120 may not be flush.

[0090] Here, the different-layer auxiliary color resist 171 can include a first part located on the surface of the first color resist 161 opposite to the light-emitting layer 120, and a second part located on the surface of the first touch wiring 141 opposite to the light-emitting layer 120, and the second part is provided between two adjacent first parts. The first part has the same color as the first color resist 161, and the first part may be integrated with the first color resist 161. Also, the two first parts adjacent to the second part can include the first color and the second color, the second part has a first end and a second end, the first end is provided close to the first part of the first color, the first end has the first color, and the first end can be integrated with the adjacent first part provided nearby; the second end is provided close to the first part of the second color, the second end has the second color, and the second end can be integrated with the adjacent first part provided nearby. Alternatively, the second part can have the same color as one of the two adjacent first parts, and the second part can be integrated with the first part having the same color.

[0091] In this case, the first color resist 161 and the different-layer auxiliary color resist 171 can cover the surface and the side wall surface of the first touch wiring 141 opposite to the light-emitting layer 120, form a good wrapping around the first touch wiring 141, and form protection for the first touch wiring 141. The first insulating layer 143 can be partially or entirely replaced by adopting the different-layer auxiliary color resist 171 and the first color resist 161, and as a result, it is advantageous for the weight reduction of the display panel 100 and the display device.

[0092] Exemplarily, the different-layer auxiliary color resist 171 can be located on the surface of the first touch wiring 141 facing the light-emitting layer 120. When the first color resist 161 is also provided simultaneously, the different-layer auxiliary color resist 171 may be located on the surface of the first color resist 161 facing the light-emitting layer 120, that is, the different-layer auxiliary color resist 171 can simultaneously cover the surfaces of the first touch wiring 141 and the first color resist 161 facing the light-emitting layer 120. The different-layer auxiliary color resist 171 can include a first portion located on the surface of the first color resist 161 facing the light-emitting layer 120 and a second portion located on the surface of the first touch wiring 141 facing the light-emitting layer 120. Since the principle has already been explained, it will not be repeated here. In this case, the first color resist 161 and the different-layer auxiliary color resist 171 cover the surface and the side wall surface of the first touch wiring 141 facing the light-emitting layer 120, can form a good wrapping around the first touch wiring 141, and can form protection for the first touch wiring 141. In the embodiment where the buffer layer is provided, the first color resist 161 and the different-layer auxiliary color resist 171 can completely or partially replace the buffer layer, and as a result, it is advantageous for reducing the weight of the display panel 100 and the display device.

[0093] In addition, the different-layer auxiliary color resist 171 in the above embodiment can be provided on at least one of the opposite sides along the thickness direction of the first touch wiring 141.

[0094] Exemplarily, as shown in FIG. 10, the different-layer auxiliary color resist 171 can be located on the surface of the second touch wiring 142 opposite to the light-emitting layer 120. In this case, the different-layer auxiliary color resist 171 and the second color resist 162 can partially replace the second insulating layer 144, and the different-layer auxiliary color resist 171 and the second color resist 162 form good protection for the second touch wiring 142. Further, the different-layer auxiliary color resist 171 can be located on the surface of the second touch wiring 142 facing the light-emitting layer 120. In this case, the different-layer auxiliary color resist 171 and the second color resist 162 can partially or completely replace the first insulating layer 143. The different-layer auxiliary color resist 171 can include a third portion covering the surface of the second color resist 162 and a fourth portion covering the surface of the second touch wiring 142. Since the principle thereof is similar to the arrangement principle of the first portion and the second portion, it will not be repeatedly described here.

[0095] As shown in FIG. 11, in the touch layer 140, a side auxiliary color resist 172 can be provided on the side close to the light-emitting area 100c of the non-light-emitting area 100d. Here, the color of the side auxiliary color resist 172 is different from that of the adjacent color resist (including the first color resist 161 and / or the second color resist 162).

[0096] In the B region of FIG. 11, the case where the color resist in the touch layer 140 includes the first color resist 161 will be described as an example. The side auxiliary color resist 172 is provided at a position close to the edge of the first color resist 161, and the positional relationship between the side auxiliary color resist 172 located at a position close to the edge of the first color resist 161 and the first color resist 161 can be regarded as an "adjacent" relationship. That is, the positional relationship between the first color resist 161 and the side auxiliary color resist 172 in the B region of FIG. 11 is the "adjacent" relationship in the embodiments of the present application. For example, the pixel corresponding to the B region is the first color pixel, and the second color pixel and the third color pixel can be provided on both sides of the first color pixel. The light emitted by the first color pixel enters the B region via the first color resist 161, and the color of the light is the first color. The side auxiliary color resist 172 adjacent to the first color resist 161 is different from the first color, and since the light of the first color cannot pass through the side auxiliary color resist 172, it cannot penetrate the side auxiliary color resist 172. As a result, light mixing between adjacent pixels can be avoided.

[0097] In some examples, in the B region, the side auxiliary color resist 172 close to the second color pixel may have the second color. As a result, only the light of the second color can pass through, and light mixing between adjacent pixels can be avoided. Also, the side auxiliary color resist 172 close to the third color pixel may have the third color. As a result, only the light of the third color can pass through, and light mixing between adjacent pixels can be avoided. Alternatively, the color of the side auxiliary color resist 172 close to the second color pixel and the color of the side auxiliary color resist 172 close to the third color pixel may both be the second color or the third color. As a result, the two side auxiliary color resists 172 can be manufactured simultaneously.

[0098] In some embodiments, the light filter layer can include a light shielding layer 150. The light shielding layer 150 can be formed from a material capable of blocking light and can absorb the light irradiated on the light shielding layer 150.

[0099] Hereinafter, the light-shielding layer 150 provided by the embodiments of the present application will be described.

[0100] The light-shielding layer 150 is located on the side closer to the light-emitting side of the touch layer 140, and the light-shielding layer 150 is located on the side opposite to the light-emitting layer 120 of the touch layer 140. By positioning the light-shielding layer 150 within the non-light-emitting area 100d, it is possible to avoid the influence of the light-shielding layer 150 on the light-emission rate of the display panel 100.

[0101] Exemplarily, as shown in FIG. 1, the light-shielding layer 150 includes a first light-shielding layer 151 and a second light-shielding layer 152. The first light-shielding layer 151 is located in the non-light-emitting area 100d of the display area 100a. The second light-shielding layer 152 is located in the non-display area 100b. The first light-shielding layer 151 and the second light-shielding layer 152 can have the same or different parameters such as thickness, length, and width. The first light-shielding layer 151 and the second light-shielding layer 152 can have an overlapping portion in the thickness direction or can be provided with a gap in the thickness direction. The embodiments of the present application do not limit this.

[0102] In addition, by providing the second light-shielding layer 152, since the light-shielding effect of the second light-shielding layer 152 is good, in this case, the ink layer in the non-light-emitting area 100d can be omitted to simplify the manufacturing process. Also, since the second light-shielding layer 152 has higher connection stability with other structural layers than the ink layer, the sealing performance between the display panels 100 can be improved, and the service life of the display panel 100 can be extended.

[0103] Exemplarily, in the display area 100a, the orthographic projection of the light-shielding layer 150 on the plane where the first touch wiring 141 is arranged can cover the first touch wiring 141, and the orthographic projection of the light-shielding layer 150 on the light-emitting layer 120 can cover the orthographic projection of the first touch wiring 141 on the light-emitting layer 120, that is, the dimension of the light-shielding layer 150 is equal to or greater than the dimension of the first touch wiring 141. As a result, the reflection of the ambient light irradiated on the first touch wiring 141 can be avoided, and the display effect of the display panel 100 can be improved.

[0104] Here, the plane on which the first touch wiring 141 is disposed refers to the plane on which the entire first touch wiring 141 is disposed, and both the length extension direction and the width extension direction of the first touch wiring 141 are within the plane.

[0105] Exemplarily, in the display area 100a, the orthographic projection of the light shielding layer 150 on the plane on which the second touch wiring 142 is disposed can cover the second touch wiring 142, and the orthographic projection of the light shielding layer 150 on the light emitting layer 120 can cover the orthographic projection of the second touch wiring 142 on the light emitting layer 120, that is, the dimension of the light shielding layer 150 is equal to or greater than the dimension of the second touch wiring 142. As a result, the reflection of the ambient light irradiated on the second touch wiring 142 can be avoided, and the display effect of the display panel 100 can be improved.

[0106] In an embodiment in which the dimension of the color resist is larger than the dimension of the pixel, at least a part of the color resist (the first color resist 161 and / or the second color resist 162) extends to the non-light emitting area 100d, and the orthographic projection of the color resist located in the non-light emitting area 100d on the plane on which the light shielding layer 150 is disposed at least partially overlaps with the light shielding layer 150. At this time, the orthographic projection of the color resist in the non-light emitting area 100d on the light emitting layer 120 at least partially overlaps with the orthographic projection of the light shielding layer 150 on the light emitting layer 120. In this way, since the area of the color resist is increased, more ambient light irradiates the color resist, the filtering effect of the ambient light is improved, and as a result, the reflection of the ambient light can be better suppressed, and the display effect of the display panel 100 can be improved. In this case, since the light shielding layer 150 overlaps with the edge of the color resist, it is possible to avoid that a part of the region between the light shielding layer 150 and the color resist is not covered by the light filter layer (it will be highly reflective if not covered by the light filter layer) after the light shielding layer 150 is displaced from a predetermined position due to manufacturing errors, and avoid the influence on the display effect of the display panel 100.

[0107] Exemplarily, as shown in FIG. 1, in the light-shielding layer 150, there are a plurality of second openings 182 provided at intervals, and the orthographic projection of the second opening 182 on the light-emitting layer 120 covers the pixel layer 121. Therefore, the influence of the light-shielding layer 150 on the aperture ratio of the display panel 100 can be avoided. Here, the second opening 182 can be circular in shape. Naturally, the second opening 182 can be any one or more of shapes such as elliptical, polygonal (quadrilateral, pentagonal, hexagonal, etc.). Because there are many choices, there are many applicable scenarios.

[0108] Here, the numerical values and numerical ranges according to the embodiments of the present application are approximate values, and due to the influence of the manufacturing process, there may be a certain range of errors that can be ignored by those skilled in the art.

[0109] Finally, it should be noted that each of the above embodiments is for explaining the technical solution of the present application and does not limit it. Although the present application has been described in detail with reference to the above-described embodiments, those skilled in the art can still modify the technical solutions described in the above-described embodiments, or perform equivalent substitutions on some or all of their technical features. It should be understood that these modifications or substitutions do not deviate from the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
