[0048] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the present invention described herein.

[0050] In order to enhance the anti-peeping effect of a display panel and improve the light emission at a specific viewing angle, the present application proposes a display panel and a display device.

[0051] Figure 1 is a schematic diagram of the structure of a display panel according to an embodiment of the present application. Figure 1 , Figure 2 as well as Figures 5 to 7 As shown, including:

[0052] Display substrate 10;

[0053] A pixel definition layer, located on one side of the display substrate 10, the pixel definition layer includes a plurality of pixel definition parts 20, and an opening area 50 is provided between two adjacent pixel definition parts 20;

[0054] Specifically, the pixel definition layer is used to define the specific position of the light emitting layer 30, that is, the specific position of the sub-pixel. The colors of two adjacent sub-pixels may be the same or different.

[0055] A plurality of sub-pixels, each of which comprises a light-emitting layer 30, wherein at least a portion of the light-emitting layer 30 is located in the opening region 50;

[0056] In practical applications, the light-emitting layer 30 may completely fill the opening area 50 or partially fill the opening area 50 , that is, the orthographic projection of the light-emitting layer 30 on the display substrate 10 partially overlaps or completely overlaps with the orthographic projection of the opening area 50 on the display substrate 10 .

[0057] A support layer, located at a side of the light emitting layer 30 away from the display substrate 10, the support layer includes a plurality of support portions 40, the support portions 40 are located at a side of the pixel definition portion 20 away from the display substrate 10, and the support portions 40 include a first support portion 401;

[0058] In practical applications, the support layer is used to support and maintain a fixed distance between the array substrate and the color filter substrate in the display panel, and the material of the support layer may be a photoresist material. It should be noted that the multiple support portions 40 include a main column and an auxiliary column. The main column is the support portion 40 that always works under the normal working environment of the display panel; the auxiliary column is to increase the overall support strength of the support layer by supporting the array substrate when the display panel is accidentally subjected to external pressure, so as to prevent the display panel from being damaged by external forces. Those skilled in the art can set the support layer material according to factors such as density, thickness, height, step difference and compression rate to achieve the best display effect. In addition, the thickness of the support layer is greater than the thickness of the pixel definition layer. The shape of the cross section of each of the support portions 40 along the first direction X1 may be as follows: Figure 1 The trapezoid shown may also be a semicircle or a rectangle.

[0059] Along the first direction X1, the opening area 50 includes a first opening area 501 adjacent to the first supporting portion 401 and a second opening area 502 adjacent to the first supporting portion 401, and along the first direction X1, the minimum distance between the first supporting portion 401 and the first opening area 501 is D1, and the minimum distance between the first supporting portion 401 and the second opening area 502 is D2, D1≠D2, wherein the first direction X1 is perpendicular to the thickness direction of the display substrate 10.

[0060] Specifically, the first opening area 501 and the second opening area 502 are located on both sides of the first support portion 401, and the first opening area 501 and the second opening area 502 are adjacent to the first support portion 401. The above D1 and D2 are the minimum distances from the same point of the first support portion 401 to one end of the first opening area 501 close to the first support portion 401 and one end of the second opening area 502 close to the first support portion 401 in the first direction X1, respectively, and the point can be located on the central axis of the first support portion 401 in the second direction. D1 can be greater than D2, and D1 can also be less than D2. D1≠D2 means that in the second direction, the central axis of the first support portion 401 and the central axis of the corresponding pixel definition portion 20 are not on the same straight line, wherein the second direction is perpendicular to the first direction X1, and the second direction is the thickness direction of the display substrate 10.

[0061] In the display panel in the above embodiment, since the minimum distance between the first support portion and the first opening area is not equal to the minimum distance between the first support portion and the second opening area, the angle between the light emitted from the first opening area and the plane where the light-emitting layer is located is the first angle, and the angle between the light emitted from the second opening area and the plane where the light-emitting layer is located is the second angle. Therefore, the first angle and the second angle are not equal. In addition, the first support portion is arranged on the pixel definition portion, which can block the wide-angle light emitted from the first opening area and the second opening area, and can achieve the differentiation of light emission from the first opening area and the second opening area in different directions and different positions, thereby improving the differentiated anti-peeping effect of the display panel, and solving the technical problem of how to improve the differentiated anti-peeping effect of the display panel in the prior art.

[0062] In another specific embodiment, Figure 2 As shown, the support portion 40 further includes a second support portion 402, which is a support portion 40 adjacent to the first support portion 401 among the plurality of support portions 40, and along the first direction X1, the first opening area 501 is located between the first support portion 401 and the second support portion 402, the first support portion 401 and the second support portion 402 are located on both sides of the first opening area 501, and the first support portion 401 and the second support portion 402 are both adjacent to the first opening area 501. The distance between the second support portion 402 and the first opening area 501 is D3, that is, D3 is the minimum distance between the second support portion 402 and one end of the first opening area 501 close to the second support portion 402, and D1≠D3. Since the minimum distance between the first support portion 401 and the first opening area 501 and the minimum distance between the second support portion 402 and the first opening area 501 are not equal, the angle between the light emitted from the first opening area 501 in the direction of the first support portion 401 and the plane where the light-emitting layer 30 is located is the third angle, and the angle between the light emitted from the first opening area 501 in the direction of the second support portion 402 and the plane where the light-emitting layer 30 is located is the fourth angle. Therefore, the third angle and the fourth angle are different in angle, which can achieve differentiated light emission of the first opening area 501 in different directions, further improving the differentiated anti-peeping effect of the display panel.

[0063] Specifically, in addition to the above Figure 1 and Figure 2 The D1 shown in the figure can also be the minimum distance between the central axis of the first support portion 401 and the central axis of the first opening area 501 along the first direction X1. Figure 2D3 shown, the above D3 may also be the minimum distance between the central axis of the second support portion 402 and the central axis of the first opening area 501 along the first direction X1. D1 may be greater than D3, and D1 may also be less than D3. D1≠D3 means that in the second direction, the central axis of the above second support portion 402 and the central axis of the corresponding pixel definition portion 20 are not on the same straight line. In another specific embodiment, along the above first direction X1, the above second opening area 502 is located between the above first support portion 401 and the above second support portion 402, and the distance between the above second support portion 402 and the above second opening area 502 is D3, and D2≠D3. Since the minimum distance between the first support portion 401 and the second opening area 502 and the minimum distance between the second support portion 402 and the second opening area 502 are not equal, the angle between the light emitted from the second opening area 502 in the direction of the first support portion 401 and the plane where the light-emitting layer 30 is located is the fifth angle, and the angle between the light emitted from the second opening area 502 in the direction of the second support portion 402 and the plane where the light-emitting layer 30 is located is the sixth angle. Therefore, the fifth angle and the sixth angle are different in angle, which can achieve differentiated light emission of the second opening area 502 in different directions, further improving the differentiated anti-peeping effect of the display panel.

[0064] In another specific embodiment, Figure 3 As shown, one of the above-mentioned supporting parts 40 is arranged on the surface of the above-mentioned pixel definition part away from the above-mentioned display substrate 10. Among the multiple above-mentioned pixel definition parts, the supporting part 40 is arranged on the surface of some pixel definition parts away from the display substrate 10, that is, there are multiple sub-pixels between two adjacent supporting parts 40 along the first direction X1, and the colors of the multiple light-emitting layers 30 are different. Since the sub-pixel includes the above-mentioned light-emitting layer 30, one of the above-mentioned light-emitting layers 30 can represent one sub-pixel, and three adjacent sub-pixels constitute a pixel unit 31. In other words, along the first direction X1, supporting parts 40 are arranged on both sides of each pixel unit 31, which can further effectively reduce the large-viewing-angle light emission of the pixel, thereby further improving the differentiated anti-peeping effect of the display panel.

[0065] In order to further enhance the differentiated anti-peeping effect of the display panel, such as Figure 4 As shown, in some embodiments of the present application, each of the above-mentioned pixel definition parts is arranged in a one-to-one correspondence with each of the above-mentioned support parts 40. That is, the above-mentioned support part 40 is arranged on the side of each pixel definition part away from the display substrate 10. Along the first direction X1, since the sub-pixel includes the above-mentioned light-emitting layer 30, one of the above-mentioned light-emitting layers 30 can represent one sub-pixel, and support parts 40 are arranged on both sides of each sub-pixel. Within a unit area, the density of the support parts 40 is greater, which can further effectively reduce the large-viewing-angle light emission of the sub-pixel, thereby further improving the differentiated anti-peeping effect of the display panel.

[0066] Specifically, the specific position of the support portion 40 is not limited to the above Figure 3 and Figure 4 The positions shown in the figure can be set by technicians in this field according to actual conditions and light output requirements, and will not be described in detail here.

[0067] In another specific embodiment, Figure 5 As shown, the display panel further includes: a first light shading layer, located on the side of the supporting layer away from the pixel definition layer, the first light shading layer includes a plurality of spaced first light shading portions 60, the first light shading portions 60 at least partially cover the supporting portion 40, and in the first direction X1, the average width of the first light shading portions 60 is greater than or equal to the minimum width of the supporting portion 40. The above-mentioned first shading portion 60 includes a first predetermined shading portion 601, and the above-mentioned first predetermined shading portion 601 can be any one of the first shading portions 60; along the above-mentioned first direction X1, the above-mentioned first opening area 501 and the above-mentioned second opening area 502 are located on both sides of the above-mentioned first predetermined shading portion 601, and are adjacent to the above-mentioned first predetermined shading portion 601, and along the above-mentioned first direction X1, the minimum distance between the above-mentioned first predetermined shading portion 601 and the above-mentioned first opening area 501 is L1, and the minimum distance between the above-mentioned first predetermined shading portion 601 and the above-mentioned second opening area 502 is L2, and the above-mentioned L1 and L2 are the minimum distances from the same point of the first predetermined shading portion 601 in the first direction X1 to one end of the first opening area 501 close to the above-mentioned first predetermined shading portion 601 and one end of the second opening area 502 close to the first predetermined shading portion 601, respectively, and the point can be located on the central axis of the first predetermined shading portion 601 in the second direction. L1≠L2, L1 can be greater than L2, and L1 can also be less than L2. L1≠L2 means that in the second direction, the central axis of the first predetermined light shielding portion 601 and the central axis of the corresponding pixel definition portion are not on the same straight line. Among them, the orthographic projection of the first light shielding portion 60 on the display substrate and the orthographic projection of the pixel definition portion on the display substrate at least partially overlap. In the first direction X1, the average width of the first light shielding portion 60 is less than or equal to the minimum width of the pixel definition portion. Since the minimum distance between the first predetermined light shielding portion 601 and the first opening area 501 and the minimum distance between the first predetermined light shielding portion 601 and the second opening area 502 are not equal, the first angle and the second angle are not equal. The first predetermined light shielding portion 601 and the first support portion 40 are used as a barrier for the large-viewing-angle light emitted from the first opening area 501 and the second opening area 502 at the same time, so that the light output of the first opening area 501 and the second opening area 502 can be differentiated in different directions and positions, thereby further improving the differentiated anti-peeping effect of the display panel.

[0068] Specifically, the first light shielding layer can be a black matrix (BM for short). Generally, the BM is located at the outermost side of the display panel, i.e., the black border portion in the display device, and is used to prevent the internal light from leaking out from the edge of the display panel. Therefore, the width of the first light shielding portion should not be too narrow. In addition, when the colors of the sub-pixels corresponding to the two adjacent light-emitting layers are different, the first light shielding portion can also be used to separate the light-emitting layers and enhance the color contrast of the sub-pixels. In practical applications, the material of the first light shielding layer can be an organic material or an inorganic material.

[0069] In order to further enhance the differentiated anti-peeping effect of the display panel, such as Figure 5 As shown, L1=D1 and / or L2=D2. That is to say, the central axis of the first predetermined light shielding portion 601 coincides with the central axis of the first supporting portion 401 in the second direction. The first predetermined light shielding portion 601 and the first supporting portion 401 simultaneously serve as blocking walls for the wide-angle light emitted from the first opening area 501 and the second opening area 502, and the first predetermined light shielding portion 601 and the first supporting portion 401 have the same shielding effect on the light emitted from the first opening area 501 and the light emitted from the second opening area 502, thereby further improving the differentiated anti-peeping effect of the display panel.

[0070] In another specific embodiment, Figure 6 As shown, L1≠D1 and / or L2≠D2. That is to say, in the second direction, the central axis of the first predetermined shading portion 601 does not coincide with the central axis of the first supporting portion 401. The first predetermined shading portion 601 and the first supporting portion 401 simultaneously serve as blocking walls for the wide-angle light emitted from the first opening area 501 and the second opening area 502, and the first predetermined shading portion 601 and the first supporting portion 401 have different shielding effects on the light emitted from the first opening area 501 and the light emitted from the second opening area 502, and further use various different light emission requirements, thereby further enhancing the diversity of differentiated anti-peeping effects of the display panel.

[0071] Specifically, L1 may be greater than D1, or L1 may be smaller than D1. L2 may be greater than D2, or L2 may be smaller than D2. Furthermore, the sum of L1 and L2 and the sum of D1 and D2 are the widths of the corresponding pixel definition parts in the first direction.

[0072] In another specific embodiment, Figure 7As shown, the first shading portion 60 further includes a second predetermined shading portion 602, and the second predetermined shading portion 602 is a support portion 40 adjacent to the first predetermined shading portion 601 among the plurality of first shading portions 60, and along the first direction X1, the first opening region 501 is located between the first predetermined shading portion 601 and the second predetermined shading portion 602, and the first predetermined shading portion 601 and the second predetermined shading portion 602 are located on both sides of the first opening region 501, and the first predetermined shading portion 601 and the second predetermined shading portion 602 are both adjacent to the first opening region 501. And the distance between the second predetermined shading portion 602 and the first opening region 501 is L3, that is, L3 is the minimum distance between the second predetermined shading portion 602 and one end of the first opening region 501 close to the second predetermined shading portion 602, and L1≠L3. Since the minimum distance between the first predetermined light-shielding portion 601 and the first opening area 501 and the minimum distance between the second predetermined light-shielding portion 602 and the first opening area 501 are not equal, the angle between the light emitted from the first opening area 501 in the direction of the first predetermined light-shielding portion 601 and the plane where the light-emitting layer 30 is located is the seventh angle, and the angle between the light emitted from the first opening area 501 in the direction of the second predetermined light-shielding portion 602 and the plane where the light-emitting layer 30 is located is the eighth angle. Therefore, the seventh angle and the eighth angle are different in angle, which can achieve differentiated light emission of the first opening area 501 in different directions, thereby further enhancing the differentiated anti-peeping effect of the display panel.

[0073] Specifically, in addition to the above Figure 5 and Figure 6 The L1 shown in the figure can also be the minimum distance between the central axis of the first predetermined light shielding portion 601 and the central axis of the first opening area 501 along the first direction X1. Figure 7 L3 shown, the above L3 may also be the minimum distance between the central axis of the second predetermined light shielding portion 602 and the central axis of the first opening area 501 along the first direction X1. L1 may be greater than L3, or L1 may be less than L3. L1≠L3 means that in the second direction, the central axis of the above second predetermined light shielding portion 602 and the central axis of the corresponding pixel definition portion are not on the same straight line.

[0074] In another specific embodiment, Figure 7 As shown, the orthographic projection of the first light shielding portion 60 on the display substrate covers the orthographic projection of the support portion 40 on the display panel. In other words, the maximum width of the first light shielding portion 60 is greater than the maximum width of the support portion 40. In practical applications, the actual light output of the display panel depends more on the blocking effect of the first light shielding layer, and the support layer plays an auxiliary role. Therefore, the above setting can further enhance the light shielding effect of the first light shielding layer, thereby further enhancing the differentiated anti-peeping effect of the display panel.

[0075] In order to further improve the stability of the display panel, such as Figures 5 to 7 As shown, the display panel further includes: an encapsulation layer 70, located between the first light shielding layer and the support layer. The encapsulation layer 70 can block the invasion of water and oxygen into the light-emitting layer, improve the encapsulation effect of the display panel, protect the light-emitting layer 30 from being corroded, and further extend the life of the display panel.

[0076] In practical applications, the encapsulation layer may be a single-layer structure or a multi-layer structure. The material of the encapsulation layer may be an organic material or an inorganic material. In a specific embodiment, the encapsulation layer may be composed of an organic material layer and an inorganic material layer alternately stacked, thereby improving the encapsulation effect of the encapsulation layer.

[0077] In another specific embodiment, Figure 8 As shown, the display panel further includes: a first organic layer 71, which is located on the side of the support layer away from the display substrate 10; the first organic layer 71 fills the opening area 50 between adjacent pixel definition parts 20 and between adjacent support parts 40, and the first organic layer 71 is also located on the surface of the support part 40 away from the pixel definition part 20, that is, the maximum thickness of the first organic layer 71 is greater than the sum of the maximum thickness of the pixel definition part 20 and the maximum thickness of the support part 40. The second organic layer 72 is located on the side of the first organic layer 71 away from the light-emitting layer 30, and the material of the first organic layer 71 is different from that of the second organic layer 72. The refractive index of the second organic layer 72 is greater than the refractive index of the first organic layer 71. Therefore, in the process of the light emitted by the light-emitting layer 30 entering the second organic layer 72 from the first organic layer 71, the refraction angle becomes smaller, further improving the focusing effect. At the same time, since D1≠D2, the angles of the light reaching the interface between the first organic layer 71 and the second organic layer 72 are different, and after being refracted by the second organic layer 72, the angles of the emitted light are also different. The light emitted from the opening area 50 in different directions can be differentiated, further improving the differentiated anti-peeping effect of the display panel.

[0078] Specifically, the materials of the first organic layer and the second organic layer may be one or more of epoxy resin, acrylic resin, polycarbonate, silicone rubber, polyurethane and polyimide. Those skilled in the art may select the materials according to actual needs, which will not be described in detail here.

[0079] like Figures 8 to 16As shown in FIG. 1 , the minimum distances between the two ends of the second organic layer 72 and the center of the sub-pixel are different. Since K1≠K2, the angles at which the light emitted by the sub-pixel reaches the two ends of the second organic layer 72 are also different. This can achieve the differentiation of the light emitted from the opening area 50 in different directions, further improving the differentiated anti-peeping effect of the display panel. It should be noted that the specific positions of the pixel definition part 20 and the support part 40 are different from those of the pixel definition part 20 and the support part 40. Figure 1 The same as in will not be repeated here.

[0080] Specifically, Figures 8 to 16 As shown, the central axis of the second organic layer 72 and the central axis of the light-emitting layer 30 are not on the same straight line along the second direction. The minimum distance between the first end of the second organic layer 72 and the center of the sub-pixel is K1, and the minimum distance between the second end of the second organic layer 72 and the center of the sub-pixel is K2, K1≠K2, K1 can be greater than K2, and K1 can also be less than K2.

[0081] In another specific embodiment, Figures 8 to 16 As shown, the first organic layer 71 includes a plurality of spaced first organic layer openings. In practical applications, since the thickness of the support layer is much greater than the thickness of the pixel definition layer and the organic material has a leveling property, during the deposition of the first organic layer 71, the first organic layer openings are formed at positions corresponding to the opening regions 50. The average thickness of the first organic layer openings is related to the average thickness of the sub-pixels, the average thickness of the pixel definition layer, and the average thickness of the support layer. The orthographic projection of the first organic layer openings on the display substrate overlaps with the orthographic projection of the opening region 50 on the display substrate. In practical applications, the orthographic projection of the first organic layer openings on the display substrate may overlap partially or completely with the orthographic projection of the opening region 50 on the display substrate. In addition, the second organic layer 72 is located in the first organic layer openings, and the surface of the second organic layer 72 away from the first organic layer 71 is flush with the top of the first organic layer openings.

[0082] Specifically, the present application does not limit the specific shape of the opening of the first organic layer. The shape of the bottom of the opening of the first organic layer can be a straight line or a curve.

[0083] In another specific embodiment, Fig. 9As shown, the surface of the opening of the first organic layer 71 facing the display substrate 10 is a concave surface, the bottom surface of the opening of the first organic layer 71 protrudes toward the display substrate 10, and the distance from the bottom of the opening of the first organic layer 71 to the display substrate 10 is smaller than the distance from the edge of the opening of the first organic layer 71 to the display substrate 10. The surface of the second organic layer 72 close to the display substrate 10 is a convex surface. The surface of the second organic layer 72 close to the display substrate 10 protrudes toward the display substrate 10. Since the first organic layer 71 and the second organic layer 72 form corresponding concave-convex structures, the second organic layer 72 can form a semi-convex lens, reduce the refraction angle of the light-emitting layer, and further improve the focusing effect.

[0084] Specifically, the concave surface of the first organic layer and the convex surface of the second organic layer may be fully matched or partially matched. When the concave surface of the first organic layer and the convex surface of the second organic layer are fully matched, optical loss of light during transmission from the first organic layer to the second organic layer can be reduced.

[0085] In another specific embodiment, Fig.10 and Fig.11 As shown, the display panel further includes: a third organic layer 73, which is located on a portion of the surface of the second organic layer 72 on a side away from the first organic layer 71, and the third organic layer 73 and the second organic layer 72 are made of different materials. The refractive index of the third organic layer 73 is greater than the refractive index of the second organic layer 72. Therefore, in the process of light entering the third organic layer 73 from the second organic layer 72, the refraction angle becomes smaller, further improving the focusing effect. At the same time, since D1≠D2, the angles of the light reaching the interface between the first organic layer 71 and the second organic layer 72 are different, and after being refracted by the second organic layer 72 and the third organic layer 73, the angles of the outgoing light are also different. The outgoing light of the opening area 50 can be differentiated in different directions, further improving the differentiated anti-peeping effect of the display panel.

[0086] Specifically, the material of the third organic layer may be one or more of epoxy resin, acrylic resin, polycarbonate, silicone rubber, polyurethane and polyimide. Those skilled in the art may select the material according to actual needs, which will not be described in detail here.

[0087] In another specific embodiment, Fig.10 and Fig.11, the orthographic projection of the third organic layer 73 on the display substrate 10 at least partially overlaps with the orthographic projection of the sub-pixel on the display substrate 10. The above arrangement can ensure that at least part of the light emitted by the sub-pixel can be refracted by the first organic layer 71, the second organic layer 72 and the third organic layer 73 in sequence to adjust the refraction angle. And after being refracted by the first organic layer 71, the second organic layer 72 and the third organic layer 73, the angles of the emitted light are also different. The light emitted from the opening area 50 in different directions can be differentiated, further improving the differentiated anti-peeping effect of the display panel.

[0088] In another specific embodiment, the orthographic projection of the third organic layer 73 on the display substrate 10 completely overlaps with the orthographic projection of the sub-pixel on the display substrate 10, or the orthographic projection of the third organic layer 73 on the display substrate 10 completely overlaps with the orthographic projection of the second organic layer 72 on the display substrate 10.

[0089] In another specific embodiment, Fig.12 As shown, the third organic layer 73 includes a first organic part 731 and a second organic part 732, and the materials of the first organic part 731 and the second organic part 732 are different. The orthographic projection of the first organic part 731 on the display substrate 10 overlaps at least partially with the orthographic projection of the sub-pixel on the display substrate 10, and the above arrangement can ensure that at least part of the light emitted by the sub-pixel can be refracted by the first organic layer 71, the second organic layer 72 and the first organic part 731 in sequence, so as to adjust the refraction angle. The orthographic projection of the second organic part 732 on the display substrate 10 overlaps at least partially with the orthographic projection of the sub-pixel on the display substrate 10, and the above arrangement can ensure that at least part of the light emitted by the sub-pixel can be refracted by the first organic layer 71, the second organic layer 72 and the second organic part 732 in sequence, so as to adjust the refraction angle. The orthographic projection of the first organic part 731 on the display substrate 10 does not overlap with the orthographic projection of the second organic part 732 on the display substrate 10, and the refractive index of the first organic part 731 is less than the refractive index of the second organic part 732. The above arrangement can reduce the refraction angle of the large-viewing angle light emitted to the first organic part 731 and reduce the refraction angle of the large-viewing angle light emitted to the second organic part 732. Moreover, since the refractive index of the first organic part 731 is less than the refractive index of the second organic part 732, the angle reduced by the second organic part 732 is greater, so that the angle of the light emitted from the second organic part 732 can be greater than the angle of the light emitted from the first organic part 731, so the angles of the emitted light are not the same. The light emitted from the opening area 50 can be differentiated in different directions, further improving the differentiated anti-peeping effect of the display panel.

[0090] Specifically, the first organic part 731 and the second organic part 732 may be respectively disposed on both sides of the central axis of the light emitting layer 30. Fig.13 As shown, the third organic layer 73 only includes the first organic portion 731. Fig.14 As shown, the third organic layer 73 includes only the second organic part 732. When the third organic layer 73 includes only one of the first organic part 731 and the second organic part 732, the manufacturing process can be further reduced, thereby further reducing the manufacturing cost of the display panel.

[0091] In some other embodiments, Fig.12 As shown, the surface of the first organic part 731 away from the second organic layer 72 is a convex surface, so the first organic part 731 can form a semi-convex lens, and the second organic layer 72 can also form a semi-convex lens, and the first organic part 731 and the second organic layer 72 together form a convex lens. The surface of the second organic part 732 away from the second organic layer 72 is a convex surface. Therefore, the second organic part 732 can form a semi-convex lens, and the second organic layer 72 can also form a semi-convex lens, and the second organic part 732 and the second organic layer 72 together form a convex lens. The convex lens formed by the combination of the first organic part 731 and the second organic layer 72 can refract the light passing through the first organic layer 71, the second organic layer 72 and the first organic part 731 in sequence. The convex lens formed by the combination of the second organic part 732 and the second organic layer 72 can refract the light passing through the first organic layer 71, the second organic layer 72 and the second organic part 732 in sequence. The above two convex lens structures can further enhance the focusing effect.

[0092] Specifically, the surface of the first organic part away from the second organic layer is a convex surface, that is, the surface of the first organic part away from the second organic layer protrudes toward the side away from the display substrate. The surface of the second organic part away from the second organic layer is a convex surface, that is, the surface of the second organic part away from the second organic layer protrudes toward the side away from the display substrate.

[0093] In some other embodiments, Fig.15As shown, the display panel further includes: a fourth organic layer 74, which is located on the side of the third organic layer 73 away from the second organic layer 72. The fourth organic layer 74 is located on the surface of the first organic layer 71 away from the display substrate 10 and on the surface of the third organic layer 73 away from the display substrate 10. The arrangement of the fourth organic layer 74 can further ensure that the light emitted by the sub-pixel can be refracted by the first organic layer 71, the second organic layer 72, the third organic layer 73 and the fourth organic layer 74 in sequence to adjust the refraction angle. And after being refracted by the first organic layer 71, the second organic layer 72, the third organic layer 73 and the fourth organic layer 74, the angles of the emitted light are also different. A part of the upward large-angle light is extracted and emitted at an angle nearly perpendicular to the panel, and another part of the downward large-angle light is extracted and emitted at a large angle. The light emission differentiation of the light emitted from the opening area in different directions can be achieved, further enhancing the differentiated anti-peeping effect of the display panel.

[0094] Specifically, the material of the fourth organic layer may be one or more of epoxy resin, acrylic resin, polycarbonate, silicone rubber, polyurethane and polyimide. Those skilled in the art may make a selection according to actual needs, which will not be described in detail here. In addition, the refractive index of the fourth organic layer may be between the refractive indexes of the first organic part and the second organic part, that is, the refractive index of the fourth organic layer is greater than the refractive index of the first organic part, and less than the refractive index of the second organic part.

[0095] In some embodiments, Fig.16 As shown, the display panel further includes: a second light shielding layer, located between the fourth organic layer 74 and the first organic layer 71, the second light shielding layer includes a plurality of second light shielding portions 80 arranged at intervals, one of the second light shielding portions 80 is correspondingly arranged on a surface of the support portion 40 away from the display substrate 10, the second light shielding portion 80 at least partially covers the support portion 40, and in the first direction X1, the average width of the second light shielding portion 80 is greater than or equal to the minimum width of the support portion 40. At least part of the second light shielding portion 80 has a different minimum distance from two adjacent opening areas 50, wherein the orthographic projection of the second light shielding portion 80 on the display substrate 10 and the orthographic projection of the pixel definition portion 20 on the display substrate 10 at least partially overlap. In the first direction X1, the average width of the second light shielding portion 80 is less than or equal to the minimum width of the pixel definition portion 20. By reducing the refraction angle of the outgoing light through the above-mentioned first organic layer 71 and the second organic layer 72, and using the second shading layer as a barrier for the wide-angle light emitted from the opening area 50, it is possible to achieve differentiated light output from the opening area 50 in different directions and at different positions, thereby further improving the differentiated anti-peeping effect of the display panel.

[0096] Specifically, the second light shielding layer can be a black matrix (BM). Generally, the BM is located at the outermost side of the display panel, that is, the black border part of the display device, which is used to prevent the internal light from leaking from the edge of the display panel. Therefore, the width of the second light shielding portion should not be too narrow. In addition, when the colors of the sub-pixels corresponding to the two adjacent light-emitting layers are different, the second light shielding portion can also be used to separate the light-emitting layers and enhance the color contrast of the sub-pixels. In practical applications, the material of the second light shielding layer can be organic material or inorganic material.

[0097] In another typical embodiment of the present application, Fig.17 As shown, a display device is provided, comprising: any one of the above-mentioned display panels 100. The specific structure of the display panel 100 has been described in detail in the above-mentioned embodiments, and will not be repeated here. Fig.17 The display device shown is only for illustration purposes and may be Fig.17 The vehicle-mounted display device shown may also be any electronic device with a display function, such as a mobile phone, a tablet computer, a laptop computer, an e-reader or a television.

[0098] Since the display device provided by the embodiment of the application includes the above-mentioned display panel, therefore, when using the display device, since the minimum distance between the first support portion and the first opening area is not equal to the minimum distance between the first support portion and the second opening area, the angle between the light emitted from the first opening area and the plane where the light-emitting layer is located is the first angle, and the angle between the light emitted from the second opening area and the plane where the light-emitting layer is located is the second angle, therefore, the above-mentioned first angle and the second angle are not equal. In addition, the first support portion is arranged on the pixel definition portion, which can block the wide-angle light emitted from the first opening area and the second opening area, and can achieve the differentiation of light emission from the first opening area and the second opening area in different directions and different positions, thereby improving the differentiated anti-peeping effect of the display panel, and solving the technical problem of how to improve the differentiated anti-peeping effect of the display panel in the prior art.

[0099] In the display panel of the present application, since the minimum distance between the first support portion and the first opening area is not equal to the minimum distance between the first support portion and the second opening area, the angle between the light emitted from the first opening area and the plane where the light-emitting layer is located is the first angle, and the angle between the light emitted from the second opening area and the plane where the light-emitting layer is located is the second angle, so the first angle and the second angle are not equal. In addition, the first support portion is arranged on the pixel definition portion, which can block the wide-angle light emitted from the first opening area and the second opening area, and can achieve the differentiation of light emission from the first opening area and the second opening area in different directions and different positions, thereby improving the differentiated anti-peeping effect of the display panel, and solving the technical problem of how to improve the differentiated anti-peeping effect of the display panel in the prior art.

[0100] The display device of the present application includes a display panel. In the display panel, since the minimum distance between the first support portion and the first opening area is not equal to the minimum distance between the first support portion and the second opening area, the angle between the light emitted from the first opening area and the plane where the light-emitting layer is located is the first angle, and the angle between the light emitted from the second opening area and the plane where the light-emitting layer is located is the second angle. Therefore, the first angle and the second angle are not equal. In addition, the first support portion is arranged on the pixel definition portion, which can block the wide-angle light emitted from the first opening area and the second opening area, and can achieve the differentiation of light emission from the first opening area and the second opening area in different directions and different positions, thereby improving the differentiated anti-peeping effect of the display panel, and solving the technical problem of how to improve the differentiated anti-peeping effect of the display panel in the prior art.

[0101] The above description is only an optional embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
