The display device provided in the embodiment of the present application will be described below with reference to fig. 1 to 11.

The following describes the display panel 100 according to an embodiment of the present application.

The present embodiment provides a display panel 100, and the display panel 100 can be applied to the display device.

The display panel 100 may include a light-emitting side and a backlight side that are oppositely disposed in a thickness direction. The light-emitting side is a side for displaying a picture, and the backlight side is the other side opposite to the light-emitting side along the thickness direction of the display panel 100.

As shown in fig. 1, the display panel 100 may include an array substrate 110 and a light emitting layer 120 on the array substrate 110. The array substrate 110 has a plurality of driving units disposed therein, the plurality of driving units may be arranged in an array, and the driving units are electrically connected to the light-emitting layer 120, and the driving units are configured to provide a driving current for the light-emitting layer 120. The driving unit may include a Thin Film Transistor (TFT) and a capacitor structure. For example, the thin film transistor may include at least one of a Metal Oxide (MO) thin film transistor and a Low Temperature Poly-silicon (LTPS) thin film transistor.

The following is a description of the light-emitting layer 120 provided in the examples of the present application.

The light emitting layer 120 may include an anode layer and a cathode layer, the anode layer being positioned at a 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. The anode layer may include a plurality of anodes disposed at intervals, and the shape of the anodes may be circular, but of course, the shape of the anodes may also be any one or more of oval, polygon (such as quadrangle, pentagon, hexagon, etc.), and the like. The selection is more, and the applicable scenes are more.

As shown in fig. 1, the light emitting layer 120 may include a pixel layer 121 and a pixel defining layer 122, the pixel layer 121 being formed of a light emitting material, the pixel layer 121 and the pixel defining layer 122 being positioned between the anode layer and the cathode layer. The pixel layer 121 may generally include a plurality of pixels, which may be arranged in an array, and may include, but is not limited to, red pixels, green pixels, and blue pixels. In other examples, the plurality of pixels may also include a white pixel. The pixel defining layer 122 is located between two adjacent pixels, and the pixel defining layer 122 may be disposed around the periphery of the pixels. For example, the shape of the pixel may be a circle, but of course, the shape of the pixel may also be any one or more of an ellipse, a polygon (such as a quadrangle, a pentagon, a hexagon, etc.), and the like. The selection is more, and the applicable scenes are more.

As shown in fig. 1, the pixel defining layer 122 has a plurality of first openings 181 arranged at intervals, the first openings 181 are used for arranging pixels, and the pixels can be deposited in the first openings 181. The orthographic projection of the pixel defining layer 122 on the plane of the anode covers the edge of the anode. For example, the shape of the first opening 181 may be a circle, and of course, the shape of the first opening 181 may also be any one or more of an ellipse, a polygon (such as a quadrangle, a pentagon, a hexagon, etc.), and the like. The selection is more, and the applicable scenes are more.

The light emitting layer 120 may further include at least one of a hole injection layer, a hole transport layer, an electron blocking layer, a hole blocking layer, an electron transport layer, and an electron injection layer.

It is understood that, as shown in fig. 1, the display panel 100 may include a display area 100a and a non-display area 100b, the display area 100a being for displaying a picture, and the non-display area 100b being disposed adjacent to the display area 100 a. The non-display area 100b is located at least one side of the display area 100 a. For example, the non-display area 100b may be surrounded on the outer circumference of the display area 100 a.

As shown in fig. 2, the display area 100a may include an emitting area 100c and a non-emitting area 100d, the emitting area 100c corresponds to a pixel, and the pixel is located in the emitting area 100c, for example, the emitting area 100c and the pixel may coincide; in addition, a non-light emitting region 100d is disposed between the adjacent light emitting regions 100c, the non-light emitting region 100d may be disposed around the periphery of the light emitting region 100c, and the non-light emitting region 100d may correspond to at least a portion of the pixel defining layer 122.

As shown in fig. 1, the display panel 100 may further include an encapsulation layer 130, the encapsulation layer 130 is located on a side of the light emitting layer 120 away from the array substrate 110, and the encapsulation 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 to damage the display panel 100.

Illustratively, the encapsulation layer 130 may employ a Thin film encapsulation technology (abbreviated as TFE), the TFE encapsulation layer may include a plurality of encapsulation sub-film layers, and the TFE may employ an overlapping inorganic/organic/inorganic multi-layer stack structure. Wherein, the inorganic layer is used for effectively blocking water and oxygen, and the organic layer is used for buffering the stress in the inorganic layer.

As shown in fig. 1, the display panel 100 may further include a touch layer 140, the touch layer 140 is located on a side of the encapsulation layer 130 away from the array substrate 110, and the touch layer 140 is used for implementing a touch function.

For example, a buffer layer may be disposed between the touch layer 140 and the encapsulation layer 130, and the buffer layer may be formed of an inorganic material (e.g., silicon nitride, silicon oxide, etc.) or an organic material. Of course, the touch layer 140 may be directly disposed on the encapsulation layer 130 without disposing a buffer layer, thereby facilitating the light weight of the display panel 100. The touch layer 140 is directly contacted with the encapsulation layer 130 in the embodiment of the present application.

The touch layer 140 provided in the embodiments of the present application is explained below.

As shown in fig. 2, the touch layer 140 may include a first touch trace 141 and a second touch trace 142, where the second touch trace 142 is located on a side of the first touch trace 141 close to the light emitting side, that is, the second touch trace 142 is located on a side of the first touch trace 141 away from the light emitting layer 120.

In the touch layer 140, one of the first touch trace 141 and the second touch trace 142 is a bridging layer, and the other of the first touch trace 141 and the second touch trace 142 can be a touch function layer. The touch function layer may include a plurality of first touch electrodes extending in a first direction, and a plurality of second touch electrodes extending in a second direction. The first direction and the second direction are different, for example, the first direction may be a length direction of the display panel 100, and the second direction may be a width direction of the display panel 100.

The length, width and thickness of the embodiments are described herein for convenience of description only and are not meant to be any limitations on dimensions. For example, the length may be greater than, equal to, or less than the width.

Illustratively, 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. It should be noted that, although both the driving electrode and the sensing electrode are formed by the second touch trace 142, the driving electrode and the sensing electrode are insulated from each other. One of the driving electrode and the sensing electrode is a continuous and uninterrupted structure along the first direction (or the second direction), and the other of the driving electrode and the sensing electrode comprises a plurality of spaced substructures along the second direction (or the first direction) and is bridged and connected through a bridging layer.

For example, the first touch trace 141 and the second touch trace 142 may be both located in the non-light emitting region 100d, so as to avoid an influence on the aperture ratio of the display panel 100.

For example, the first touch trace 141 and the second touch trace 142 may be formed by a single conductive layer or a stacked structure of multiple conductive layers.

In some embodiments, as shown in fig. 2, the touch layer 140 may include a first insulating layer 143, and the first insulating layer 143 is located between the first touch trace 141 and the second touch trace 142 and electrically isolates the first touch trace 141 from the second touch trace 142. In addition, the touch layer 140 may further include a second insulating layer 144, and the second insulating layer 144 may be located on a side of the second touch trace 142 away from the light emitting layer 120, and may protect the first touch trace 141 and the second touch trace 142.

The display panel 100 may include a filter layer, which may be used to reduce reflection of ambient light, thereby improving the display effect of the display panel 100.

The following describes a filter layer provided in an embodiment of the present application.

The filter layer may include a color resist that may be used to filter light in the ambient light that is a different color than the light itself. The color resistor may be formed of an organic material, which has high flexibility and is beneficial to the bending performance of the display panel 100.

The color resistor may be integrated in the touch layer 140, and a structural layer in the touch layer 140, such as the first insulating layer 143 and/or the second insulating layer 144, may protect the color resistor, so that a separate barrier layer may not be required to be provided for the color resistor, and thus, the manufacturing processes of the display panel 100 and the display device may be simplified.

It can be understood that the distance between the color resistor and the light-emitting layer 120 may affect the filtering effect of the color resistor on the corresponding color light, and when the distance between the color resistor and the light-emitting layer 120 along the thickness direction is too large, the light emitted by the pixel is diffused outward to a greater extent, so that the amount of light emitted from the color resistor corresponding to the pixel may be reduced, thereby resulting in poor display viewing angle and display brightness of the display panel 100 and the display device. The color resistors are integrated in the touch layer 140, and the color resistors are closer to the pixels, so that the amount of light emitted from the corresponding color resistors of the pixels is increased, and the display viewing angle and the display brightness of the display panel 100 and the display device can be improved.

Wherein at least a portion of the color-resist is located in the light-emitting region 100c. The color resistors in the same layer may include a plurality of sub-color resistors, the sub-color resistors are disposed in one-to-one correspondence with the pixels, and the orthographic projection of the sub-color resistors on the light emitting layer 120 covers the pixels and has the same color as the covered pixels, so as to avoid the occurrence of light mixing. The plurality of sub-color resistances may include any one or more of a red sub-color resistance, a green sub-color resistance, a blue sub-color resistance, and a white sub-color resistance. For example, the sub-color resistor corresponding to the red pixel is a red sub-color resistor, and the red sub-color resistor can block light emitted by the blue pixel and the green pixel and allow red light emitted by the red pixel or the white pixel to pass through.

The size of the sub-color resistor is larger than or equal to the size of the pixel, and the orthographic projection of the sub-color resistor on the light-emitting layer 120 can cover the pixel. In some examples, the orthographic projection of the sub-color resists on the emissive layer 120 may overlap the pixel, and in this case, the sub-color resists are the same size as the pixel (e.g., the first color resist 161 in fig. 2). In other examples, the orthographic projection of the sub-color resists on the light emitting layer 120 may cover the pixel, and there is a distance between the outer edge of the orthographic projection of the sub-color resists on the light emitting layer 120 and the outer edge of the pixel, and in this case, the sub-color resists are larger than the size of the pixel, and the amount of light emitted from the sub-color resist corresponding to the pixel will be increased (e.g., the first color resist 161 in fig. 3).

The shape of the sub color resistor can be a circle, and of course, the shape of the sub color resistor can also be any one or more of an ellipse, a polygon (such as a quadrangle, a pentagon, a hexagon, etc.), and the like. The selection is more, and the applicable scenes are more.

As shown in fig. 2, the color resistor may include a first color resistor 161, and the first color resistor 161 and the first touch trace 141 are disposed in the same layer. The first color resists 161 and the first touch traces 141 are disposed in the same layer, which means that the first touch traces 141 and the first color resists 161 are prepared on the surface of the same basic structure layer along the same side of the thickness direction, for example, the first touch traces 141 and the first color resists 161 are both disposed on the surface of the package layer 130 facing away from the light emitting layer 120. The same layer setting principle in the embodiment of the present application is similar, and will not be described again.

The first color resistor 161 provided in the embodiment of the present application is explained below.

The first color resistor 161 includes a plurality of sub-color resistors disposed in the same layer, and the sub-color resistors may be first sub-color resistors, the principle of which has been already explained and will not be described again.

For example, the first color resists 161 and the first touch traces 141 may be directly prepared on the package layer 130, at this time, the first color resists 161 and the first touch traces 141 are both in contact with the package layer 130, and the first color resists 161 are closer to the light emitting layer 120, so that the display viewing angle and the display brightness of the display panel 100 and the display device can be better ensured.

For example, as shown in fig. 3, a surface of the first color resist 161 close to the light emitting side may be flush with a surface of the first touch trace 141 close to the light emitting side, so that surfaces of the first color resist 161 and the first touch trace 141 away from the light emitting layer are relatively flat. Or, as shown in fig. 4, a surface of the first color resistor 161 close to the light-emitting side may protrude from a surface of the first touch trace 141 close to the light-emitting side, which is beneficial to preventing light mixing of adjacent pixels.

In some examples, as shown in fig. 2 to fig. 4, a distance is provided between the first color resist 161 and the first touch trace 141, so that mutual interference between the first color resist 161 and the first touch trace 141 in a manufacturing process due to a process error can be avoided. In other examples, as shown in fig. 5, a side wall surface of the first color resist 161 and a side wall surface of the first touch trace 141 can be in contact with each other, so that surfaces of the first color resist 161 and the first touch trace 141, which are away from the light emitting layer 120, are relatively complete. When the surface of the first color resistor 161 away from the light emitting layer 120 is flush with the surface of the first touch trace 141 away from the light emitting layer 120, the provided surface is relatively flat. In addition, the size of the first color resistor 161 is larger, and more light can pass through the first color resistor 161, which can better ensure the display viewing angle and the display brightness of the display panel 100 and the display device.

As shown in fig. 2, the first insulating layer 143 may be located on the first touch trace 141 and a side of the first color resistor 161 away from the light emitting layer 120, and the first insulating layer 143 and other structural layers located on the first insulating layer 143 away from the light emitting layer 120 may protect the first color resistor 161, so that a separate barrier layer does not need to be provided for the first color resistor 161, and the manufacturing process of the display panel 100 and the display device may be simplified.

In some embodiments, as shown in fig. 6, the color resistors may include a second color resistor 162, and the second color resistor 162 and the second touch trace 142 are disposed on the same layer. The second color resists 162 and the second touch traces 142 can be located on a side of the first insulating layer 143 away from the light emitting layer 120.

The second color resists 162 provided in the embodiments of the present application will be described below.

The second color resistor 162 includes a plurality of sub-color resistors disposed in the same layer, and the sub-color resistors may be second sub-color resistors, the principle of which has been explained and will not be described again.

For example, a surface of the second color resistor 162 close to the light-emitting side may be flush with a surface of the second touch trace 142 close to the light-emitting side, or a surface of the second color resistor 162 close to the light-emitting side may protrude out of a surface of the second touch trace 142 close to the light-emitting side. The principle is similar to that between the first color resistor 161 and the first touch trace 141, and is not described again.

For example, as shown in fig. 6, a space may be formed between the second color resists 162 and the second touch traces 142, or, as shown in fig. 7, a side wall surface of the second color resists 162 and a side wall surface of the second touch traces 142 may be in contact with each other. The principle is similar to that between the first color resistor 161 and the first touch trace 141, and is not described again.

The first color resistor 161 and the second color resistor 162 may be separately provided or may be provided at the same time.

In some embodiments, as shown in fig. 8 to fig. 10, a different-layer auxiliary color resistor 171 can be further disposed in the touch layer 140, and the different-layer auxiliary color resistor 171 is disposed in a different layer from the first touch trace 141 and the second touch trace 142. The different-layer auxiliary color resistor 171 and the first touch trace 141 are arranged in different layers, which means that the different-layer auxiliary color resistor 171 and the first touch trace 141 are stacked in the thickness direction, wherein the different-layer auxiliary color resistor 171 and the first touch trace 141 can be in contact with each other or arranged at intervals in the thickness direction. The principle of setting the different layers in the embodiment of the present application is similar, and will not be described again.

For example, as shown in fig. 8 and fig. 9, the different-layer auxiliary color resistor 171 can be located on a surface of the first touch trace 141 facing away from the light-emitting layer 120, and if the first color resistor 161 is provided, the different-layer auxiliary color resistor 171 can also be located on a surface of the first color resistor 161 facing away from the light-emitting layer 120, that is, the different-layer auxiliary color resistor 171 can cover surfaces of the first touch trace 141 and the first color resistor 161 facing away from the light-emitting layer 120. For example, the surface of the layer auxiliary color resistor 171 facing away from the light-emitting layer 120 may be flush, so as to provide a relatively flat support surface for a structural layer to be subsequently prepared thereon. Alternatively, the surface of the layer auxiliary color resistor 171 facing away from the light-emitting layer 120 may not be flush.

The different-layer auxiliary color resistor 171 may include a first portion and a second portion, the first portion is located on a surface of the first color resistor 161 away from the light-emitting layer 120, the second portion is located on a surface of the first touch trace 141 away from the light-emitting layer 120, and the second portion is disposed between two adjacent first portions. The first portion is the same color as the first color resistor 161, and the first portion and the first color resistor 161 may be a single piece. In addition, the colors of two first portions adjacent to the second portion may include a first color and a second color, the second portion includes a first end and a second end, the first end is adjacent to the first portion of the first color, the color of the first end may be the first color, and the first end and the adjacent first portion are one piece; the second end is adjacent to the first portion of the second color, the second end may be the second color, and the second end and the adjacent first portion are a unitary piece. Alternatively, the second portion may be the same color as one of the adjacent two first portions, and the second portion may be a single piece with the first portion having the same color.

At this time, the first color resistor 161 and the different-layer auxiliary color resistor 171 can cover the side of the first touch trace 141 away from the light-emitting layer 120 and the side wall surface, so as to wrap the first touch trace 141 well, so as to protect the first touch trace 141 well. The first insulating layer 143 may be partially or entirely replaced with the different-layer auxiliary color resist 171 and the first color resist 161, which may be advantageous to the light and thin display panel 100 and the display device.

For example, the different-layer auxiliary color resistor 171 can be located on a surface of the first touch trace 141 facing the light-emitting layer 120. If the first color resist 161 is disposed at the same time, the different-layer auxiliary color resist 171 may also be located on a surface of the first color resist 161 facing the light-emitting layer 120, that is, the different-layer auxiliary color resist 171 may cover surfaces of the first touch trace 141 and the first color resist 161 facing the light-emitting layer 120 at the same time. The different-layer auxiliary color resistor 171 may include a first portion and a second portion, the first portion is located on a surface of the first color resistor 161 facing the light-emitting layer 120, and the second portion is located on a surface of the first touch trace 141 facing the light-emitting layer 120. At this time, the first color resist 161 and the different-layer auxiliary color resist 171 can cover the side surface of the first touch trace 141 facing the light-emitting layer 120 and the side wall surface, and form a better wrapping for the first touch trace 141, so as to form a better protection for the first touch trace 141. In the embodiment where the buffer layer is disposed, the first color resist 161 and the different-layer auxiliary color resist 171 may replace the buffer layer entirely or partially, thereby facilitating the lightness and thinness of the display panel 100 and the display device.

It should be noted that at least one of two opposite sides of the first touch trace 141 along the thickness direction may be provided with the different-layer auxiliary color resistor 171 in the above embodiments.

For example, as shown in fig. 10, the different-layer auxiliary color resistor 171 can be located on a surface of the second touch trace 142 away from the light-emitting layer 120, and at this time, the second insulating layer 144 can be partially replaced by the different-layer auxiliary color resistor 171 and the second color resistor 162, and the second touch trace 142 is better protected by the different-layer auxiliary color resistor 171 and the second color resistor 162. In addition, the different-layer auxiliary color resistor 171 can be located on a surface of the second touch trace 142 facing the light emitting layer 120, and at this time, the different-layer auxiliary color resistor 171 and the second color resistor 162 can partially or completely replace the first insulating layer 143. The different-layer auxiliary color resistor 171 may include a third portion and a fourth portion, the third portion covers the surface of the second color resistor 162, and the fourth portion covers the surface of the second touch trace 142.

As shown in fig. 11, a side auxiliary color resistor 172 may be disposed in the touch layer 140, and the side auxiliary color resistor 172 is located on a side of the non-light emitting region 100d close to the light emitting region 100c, where the side auxiliary color resistor 172 is different from the adjacent color resistor (including the first color resistor 161 and/or the second color resistor 162).

In the area B of fig. 11, taking the color resistor in the touch layer 140 including the first color resistor 161 as an example for description, the side auxiliary color resistor 172 is disposed near the edge of the first color resistor 161, and the position relationship between the side auxiliary color resistor 172 near the edge of the first color resistor 161 and the first color resistor 161 can be regarded as "adjacent", that is, the position relationship between the first color resistor 161 and the side auxiliary color resistor 172 in the area B of fig. 11 is "adjacent" in the embodiment of the present application. For example, the pixel corresponding to the B region is a first color pixel, a second color pixel and a third color pixel may be disposed on two sides of the first color pixel, the first color pixel emits light, which enters the B region through the first color resistor 161, and the color of the light is the first color. Since the side auxiliary color resistor 172 adjacent to the first color resistor 161 is different from the first color, the light of the first color cannot pass through the side auxiliary color resistor 172 and thus cannot pass through the side auxiliary color resistor 172, so as to avoid light mixing between adjacent pixels.

In some examples, in the B region, the color of the side auxiliary color resistor 172 near the second color pixel may be the second color, so that only the light of the second color may pass through to avoid the mixing of the adjacent pixels; in addition, the color of the side auxiliary color resist 172 close to the third color pixel may be the third color, so that only the light of the third color may pass through to avoid the light mixing of the adjacent pixels. Alternatively, the color of the side auxiliary color resistor 172 adjacent to the second color pixel and the color of the side auxiliary color resistor 172 adjacent to the third color pixel may both be the second color or the third color, so that the two side auxiliary color resistors 172 may be prepared at the same time.

In some embodiments, the light-shielding layer 150 may include the light-shielding layer 150, and the light-shielding layer 150 may be formed of a material capable of blocking light and absorbing light irradiated onto the light-shielding layer 150.

The light-shielding layer 150 according to the embodiment of the present application will be described below.

The light-shielding layer 150 is located on a side of the touch layer 140 close to the light-emitting side, and the light-shielding layer 150 is located on a side of the touch layer 140 away from the light-emitting layer 120. The light-shielding layer 150 may be located in the non-light-emitting region 100d, so as to avoid the influence of the light-shielding layer 150 on the light-emitting rate of the display panel 100.

For example, as shown in fig. 1, the light-shielding layer 150 includes a first light-shielding layer 151 and a second light-shielding layer 152, and the first light-shielding layer 151 is located in the non-light-emitting region 100d of the display region 100 a. The second light-shielding layer 152 is located in the non-display area 100 b. The first light-shielding layer 151 and the second light-shielding layer 152 may have the same or different thickness, length, width, and other parameters; the first and second light shielding layers 151 and 152 may have overlapping portions in the thickness direction or be disposed at intervals in the thickness direction. The embodiments of the present application do not limit this.

It should be noted that, due to the second light-shielding layer 152, the light-shielding effect of the second light-shielding layer 152 is better, and at this time, the ink layer in the non-light-emitting region 100d can be omitted, thereby simplifying the manufacturing process. In addition, the second light shielding layer 152 has higher connection stability between the ink layer and other structural layers, so that the sealing performance between the display panels 100 can be improved, and the service life of the display panel 100 can be prolonged.

For example, in the display area 100a, the orthographic projection of the light-shielding layer 150 on the plane where the first touch trace 141 is located may cover the first touch trace 141, and the orthographic projection of the light-shielding layer 150 on the light-emitting layer 120 may cover the orthographic projection of the first touch trace 141 on the light-emitting layer 120, that is, the size of the light-shielding layer 150 is greater than or equal to the size of the first touch trace 141. Therefore, reflection of ambient light on the first touch trace 141 can be avoided, so as to improve the display effect of the display panel 100.

The plane of the first touch trace 141 is a plane on which the first touch trace 141 is located, and the length extending direction and the width extending direction of the first touch trace 141 are both located in the plane.

For example, in the display area 100a, the orthographic projection of the light-shielding layer 150 on the plane where the second touch traces 142 are located may cover the second touch traces 142, and the orthographic projection of the light-shielding layer 150 on the light-emitting layer 120 may cover the orthographic projection of the second touch traces 142 on the light-emitting layer 120, that is, the size of the light-shielding layer 150 is greater than or equal to the size of the second touch traces 142. Therefore, reflection of ambient light on the second touch trace 142 can be avoided, so as to improve the display effect of the display panel 100.

In the embodiment where the color resists have a size larger than the pixel size, at least a portion of the color resists (the first color resist 161 and/or the second color resist 162) extend to the non-light-emitting region 100d, and an orthogonal projection of the color resists located in the non-light-emitting region 100d on the plane of the light-shielding layer 150 at least partially overlaps the light-shielding layer 150. At this time, the orthographic projection of the color resist of the non-light emitting region 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. Thus, the area of the color resistor is large, so that more ambient light can be irradiated onto the color resistor, the filtering effect on the ambient light is better, and the reflection of the ambient light can be better reduced, so as to improve the display effect of the display panel 100. At this time, the light-shielding layer 150 overlaps with the edges of the color resistors, so that it can be avoided that a part of the area between the light-shielding layer 150 and the color resistors cannot be covered by the filter layer (if the filter layer is not covered, a high reflection occurs) after the process error deviates from the predetermined position, thereby avoiding affecting the display effect of the display panel 100.

For example, as shown in fig. 1, the light-shielding layer 150 has a plurality of second openings 182 disposed at intervals, and an orthogonal projection of the second openings 182 on the light-emitting layer 120 covers the pixel layer 121, so that the light-shielding layer 150 can be prevented from affecting the aperture ratio of the display panel 100. The shape of the second opening 182 may be a circle, and of course, the shape of the second opening 182 may also be any one or more of an ellipse, a polygon (e.g., a quadrangle, a pentagon, a hexagon, etc.), and the like. The selection is more, and the applicable scenes are more.

It should be noted that the numerical values and numerical ranges related to the embodiments of the present application are approximate values, and there may be a certain range of errors depending on the manufacturing process, and the error may be considered as negligible by those skilled in the art.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and these modifications or substitutions do not depart from the scope of the technical solutions of the embodiments of the present application.
