The insulating pattern is disposed between the packaging layer and the light shielding pattern, and between the first touch electrodes and the second touch electrodes, wherein the light shielding pattern covers the insulating pattern and the first touch electrodes.

In an embodiment of the invention, the areas of the electrode regions of at least two metal electrodes are different from each other.

In an embodiment of the invention, the area occupied by at least two electroluminescent layers on the two metal electrodes is different from each other.

In an embodiment of the invention, wherein the electroluminescent layers include a plurality of first electroluminescent layers, a plurality of second electroluminescent layers, and a plurality of third electroluminescent layers, and each of the first electroluminescent layers The colors of the light emitted by the layer, each second electroluminescent layer, and each third electroluminescent layer are different from each other.

In an embodiment of the invention, the light exit ports include a plurality of first light exit ports, a plurality of second light exit ports, and a plurality of third light exit ports.

FIG. 1A is a schematic top view of a display panel according to at least one embodiment of the present invention, and FIG. 1B is a schematic cross-sectional view taken along line 1B-1B in FIG. 1A. 1A and 1B, the display panel 100 includes a control substrate 110, and the control substrate 110 has a surface 112s, and includes a plurality of metal electrodes formed on the surface 112s. Taking FIGS. 1A and 1B as examples, these metal electrodes may serve as anodes, and include a plurality of first anodes 111r, a plurality of second anodes 111g, and a plurality of third anodes 111b. That is, any one of these metal electrodes may be the first anode 111r, the second anode 111g, or the third anode 111b.

Each metal electrode may contact the surface 112s and cover part of the surface 112s, so each metal electrode will occupy an electrode area on the surface 112s. For example, the first anodes 111r occupy a plurality of first electrode regions on the surface 112s, the second anodes 111g occupy a plurality of second electrode regions on the surface 112s, and the third anodes 111b occupy a plurality of first electrodes on the surface 112s The three-electrode area, wherein the first electrode area, the second electrode area, and the third electrode area are, for example, areas filled with diagonal lines in FIG. 1A.

The display panel 100 further includes a plurality of electroluminescent layers, wherein these electroluminescent layers may have a light emitting diode structure. For example, each electroluminescent layer may include an electron transport layer, an electron injection layer, a hole transport layer, and a hole injection layer, wherein at least one of the electron transport layer, the electron injection layer, the hole transport layer, and the hole injection layer may be Made of organic materials. In other words, each electroluminescent layer can be substantially an organic light-emitting diode. In addition, each electroluminescent layer may be substantially a quantum dot light emitting diode (Quantum Dots Light Emitting Diode, QLED).

In this embodiment, these electroluminescent layers can be divided into three types, and these three types of electroluminescent layers can respectively emit three types of light with substantially different colors. The three substantially different colors mentioned here refer to the condition that, without relying on the measurement of the instrument and directly viewed with the naked eye, a normal person will intuitively think that the colors of the light emitted by the three electroluminescent layers are three. In FIGS. 1A and 1B, these electroluminescent layers may include a plurality of first electroluminescent layers 122r, a plurality of second electroluminescent layers 122g, and a plurality of third electroluminescent layers 122b, and each of the first electroluminescent layers The colors of the light emitted by the electroluminescent layer 122r, each second electroluminescent layer 122g, and each third electroluminescent layer 122b are different from each other. Taking FIG. 1B as an example, the first electroluminescent layer 122r can emit red light LR1, the second electroluminescent layer 122g can emit green light LG1, and the third electroluminescent layer 122b can emit blue light LB1.

The display panel 100 also includes a pixel definition layer 121. The pixel definition layer 121 is disposed on the surface 112s and has a plurality of pixel openings 121r, 121g, and 121b, wherein the pixel openings 121r, 121g, and 121b are connected to the metal electrodes (eg, the first anode 111r and the second anode 111g Overlaps the third anode 111b). That is to say, the pixel openings 121r, 121g and 121b will be aligned one-to-one with the metal electrodes and expose the metal electrodes respectively, wherein the electroluminescent layers (such as the first electroluminescent layer 122r, the second The electroluminescent layer 122g and the third electroluminescent layer 122b) are respectively disposed in the pixel openings 121r, 121g, and 121b and on the metal electrodes.

Taking FIGS. 1A and 1B as examples, the pixel opening 121r overlaps and aligns with the first anode 111r, the pixel opening 121g overlaps and aligns with the second anode 111g, and the pixel opening 121b overlaps and aligns with the third anode 111b. The first electroluminescent layers 122r are respectively disposed on the first anodes 111r, the second electroluminescent layers 122g are respectively disposed on the second anodes 111g, and the third electroluminescent layers 122b are respectively disposed on the first Three anodes 111b. The pixel definition layer 121 may be a photoresist after development, and the pixel openings 121r, 121g, and 121b may be formed by development, so the pixel definition layer 121 may be formed of a photoresist.

It should be noted that in the embodiments shown in FIGS. 1A and 1B, the display panel 100 includes three types of electroluminescent layers that can emit different colors of light: the first electroluminescent layer 122r that can emit red light LR1, and the green The second electroluminescent layer 122g of the light LG1 and the third electroluminescent layer 122b that can emit blue light LB1. However, in other embodiments, the display panel 100 may also include multiple single-type electroluminescent layers, such as an electroluminescent layer that emits white light. Alternatively, the display panel 100 may include more than three types of electroluminescent layers. For example, in addition to the above first electroluminescent layer 122r, second electroluminescent layer 122g, and third electroluminescent layer 122b, the display panel 100 may further include a fourth electroluminescent layer capable of emitting yellow light. Therefore, the type of the electroluminescent layer included in the display panel 100 may be only one kind or more than four kinds, and there is no limitation to only three kinds.

The display panel 100 further includes a counter electrode 124 disposed on the pixel definition layer 121 and the electroluminescent layers (eg, the first electroluminescent layer 122r, the second electroluminescent layer 122g, and the third electroluminescent layer 122b ), and can fully cover and contact the pixel definition layer 121, the first electroluminescent layer 122r, the second electroluminescent layer 122g, and the third electroluminescent layer 122b. The counter electrode 124 may be a relatively thin metal layer, so that the counter electrode 124 can allow visible light (for example, red light LR1, green light LG1, and blue light LB1) to pass through. Alternatively, the counter electrode 124 may also be a transparent conductive layer, and its material is, for example, indium tin oxide (ITO), indium zinc oxide (IZO), aluminum tin oxide (Aluminum Tin Oxide) , ATO), Aluminum Zinc Oxide (AZO) and Indium Germanium Zinc Oxide (IGZO). Therefore, the light emitted by the first electroluminescent layer 122r, the second electroluminescent layer 122g, and the third electroluminescent layer 122b (ie, red light LR1, green light LG1, and blue light LB1) can penetrate the counter electrode 124 .

Each electroluminescent layer electrically connects the counter electrode 124 and one of the metal electrodes. Taking FIG. 1B as an example, the first electroluminescent layer 122r electrically connects the counter electrode 124 and the first anode 111r, the second electroluminescent layer 122g electrically connects the counter electrode 124 and the second anode 111g, and the third electroluminescent layer The layer 122b electrically connects the counter electrode 124 and the third anode 111b, where the counter electrode 124 may serve as a cathode. In addition, the first electroluminescent layer 122r may contact the first anode 111r and the counter electrode 124, the second electroluminescent layer 122g may contact the second anode 111g and the counter electrode 124, and the third electroluminescent layer 122b may contact The third anode 111b and the counter electrode 124.

The display panel 100 further includes a light shielding pattern 130, and the light shielding pattern 130 is disposed opposite to the opposite electrode 124, wherein the opposite electrode 124 is located between the control substrate 110 and the light shielding pattern 130. The shape of the light shielding pattern 130 may be a net shape, and have a plurality of light outlets. The color of the light shielding pattern 130 may be black and opaque, so the light shielding pattern 130 can block visible light, such as red light LR1, green light LG1 and blue light LB1. In addition, the light-shielding pattern 130 may be formed by photoresist, and the light exit may be formed by development.

These light exit ports can project multiple pixel regions on the surface 112s. Taking FIGS. 1A and 1B as examples, the light exits of the light-shielding pattern 130 may include a plurality of first light exits 130r, a plurality of second light exits 130g, and a plurality of third light exits 130b. The first light outlets 130r project a plurality of first pixel regions on the surface 112s, the second light outlets 130g project a plurality of second pixel regions on the surface 112s, and the third light outlets 130b on the surface 112s Multiple third pixel regions are projected on the top. From FIG. 1A, the first pixel area is like the first light outlet 130r shown in FIG. 1A, the second pixel area is like the second light outlet 130g shown in FIG. 1A, and the third pixel area is like FIG. 1A Illustrated third light outlet 130b. In other words, the first pixel area, the second pixel area, and the third pixel area are equivalent to the area surrounded by the solid frame in FIG. 1A.

The pixel regions (for example, the first to third pixel regions) overlap with the electrode regions (for example, the regions filled with diagonal lines in FIG. 1A) to define a plurality of overlapping regions. In this embodiment, the first pixel regions overlap with the first electrode regions to define a plurality of first overlapping regions, and the second pixel regions overlap with the second electrode regions to define a plurality of first overlapping regions. Two overlapping regions, and the third pixel regions overlap with the third electrode regions to define a plurality of third overlapping regions. In other words, the first overlapping area is the area where the first anode 111r occupies the surface 112s in the first pixel area, the second overlapping area is the area where the second anode 111g occupies the surface 112s in the second pixel area, and the first The three overlapping areas are areas where the third anode 111b occupies the surface 112s in the third pixel area. In addition, the first to third overlapping regions are, for example, diagonally filled regions limited within the solid frame shown in FIG. 1A.

The average ratio between the area of the overlapping area and the area of the pixel area is less than or equal to 70%, where the method for calculating the average ratio may include the following steps. First, calculate the area ratio between at least two overlapping regions and their corresponding overlapping pixel regions to obtain at least two area ratios, where these overlapping regions can correspond to different types of electroluminescent layers, such as the first The electroluminescent layer 122r, the second electroluminescent layer 122g, and the third electroluminescent layer 122b. Next, the average of these area ratios is calculated, where this average is equal to the above average ratio.

Regarding the calculation method of the single area ratio, the second light outlet 130g, the second anode 111g, and the second electroluminescent layer 122g shown in FIGS. 1A and 1B will be taken as examples for illustration. From FIG. 1A, the shapes of the second light outlet 130g, the second anode 111g, and the second electroluminescent layer 122g are substantially square. In other words, under the condition of not relying on the measurement of the instrument and viewing directly with the naked eye, a normal person will intuitively think that the second pixel area, the second electrode area, and the second electroluminescent layer 122g occupy the surface 112s The shapes of the areas are substantially square. Therefore, the four sides E1 of the second electroluminescent layer 122g are substantially equal to each other.

Secondly, both the second electroluminescent layer 122g and the second anode 111g are substantially located in the center of the second light outlet 130g, so there is substantially fixed between the second electroluminescent layer 122g and the second light outlet 130g (Constant) distance D12, and there is substantially a fixed distance D11 between the edge of the second electroluminescent layer 122g and the edge of the second anode 111g adjacent thereto, as shown in FIGS. 1A and 1B. It should be noted that since the light outlets of the light-shielding pattern 130 can be formed by development, the side wall of the second light outlet 130g can be formed with a slope, and the distance D12 can be defined to be substantially from the middle of the side wall of the second light outlet 130g to the first The distance between the edges of the two electroluminescent layers 122g is shown in FIG. 1B.

In the embodiment shown in FIG. 1A, the second electrode area (the diagonally filled area shown in FIG. 1A) is completely located in the second pixel area (the second light outlet 130g shown in FIG. 1A) Therefore, the second electrode region may be equivalent to the second overlapping region, wherein the area A, side length E1, and distance D11 of the second overlapping region satisfy the following mathematical formula (1). A = (E1+2×D11) ² .............................................................................. (1)

Similarly, the area B, side length E1, and distance D12 of the second pixel area satisfy the following mathematical formula (2). B = (E1+2×D12) ² .............................................................................. (2)

After knowing the area A of the second overlapping area and the area B of the second pixel area, the area ratio η2 between the area A of the second overlapping area and the area B of the second pixel area satisfies the following mathematical formula (3) . η2 = (E1+2×D11) ² / (E1+2×D12) ² .................................................................. (3)

It can be seen that the distance D11 between the edge E1 of the second electroluminescent layer 122g and the edge of the second electroluminescent layer 122g and the edge of the second anode 111g adjacent thereto and the first Under the condition of the distance D12 between the second electroluminescent layer 122g and the second light outlet 130g, according to the above mathematical formula (3), a single area ratio η2 can be calculated.

Similarly, the side lengths of the first electroluminescent layer 122r and the third electroluminescent layer 122b, the edge of the first electroluminescent layer 122r, and the first anode 111r adjacent thereto are known to be substantially square in shape The distance between the edges, the distance between the edge of the third electroluminescent layer 122b and the edge of the adjacent third anode 111b, the distance between the first electroluminescent layer 122r and the first light outlet 130r, and the third Under the condition of the distance between the luminescent layer 122b and the third light outlet 130b, according to the above mathematical formula (3), a single area ratio η1 and a single area ratio η3 can be calculated, wherein the area ratio η1 overlaps each other. The area ratio between an overlapping area and the first pixel area, and the area ratio η3 is the area ratio between the third overlapping area and the third pixel area that overlap each other.

After calculating a single area ratio η1, area ratio η2, and area ratio η3, the above average ratio of less than or equal to 70% can satisfy the following mathematical formula (4), where η is the average ratio. η=(η1+η2+η3)/3.................................................................. (4)

It can be seen that, in this embodiment, the average ratio η may be the average of three area ratios η1, η2, and η3. However, in other embodiments, the average ratio η may also be the average of two or more than three area ratios. Even, the average ratio η may be equal to the ratio between the total area of all overlapping regions in the display panel 100 and the total area of all pixel regions. Therefore, the average ratio η is not limited and can only be calculated from the above mathematical formulas (1) to (4). In addition, in the embodiment shown in FIG. 1A, the shape and area of the first light outlet 130r, the second light outlet 130g, and the third light outlet 130b may be substantially the same as each other, and the first anode 111r, the second anode The shape and size of the three 111g and the third anode 111b may be substantially the same as each other. Therefore, the areas of the first to third overlapping regions can be substantially equal to each other, and the areas of the first to third pixel regions can also be substantially equal to each other.

When the external ambient light L1 is incident on the counter electrode 124 from the first light outlet 130r, the second light outlet 130g, and the third light outlet 130b of the shading pattern 130, the ambient light L1 will penetrate the counter electrode 124 and be incident on these Metal electrodes: first anode 111r, second anode 111g, and third anode 111b. Although the first anode 111r, the second anode 111g, and the third anode 111b reflect ambient light L1, since the average ratio between the area of the overlapping area and the area of the pixel area is less than or equal to 70%, these metal electrodes are The area occupied by the surface 112s is not large, thereby helping to reduce the reflection of the ambient light L1 by the metal electrode, thereby weakening the interference of the reflected ambient light L1 on the image.

FIG. 1C is a schematic diagram of the relationship between the side length and the area ratio of the electroluminescent layer in FIG. 1A. Please refer to FIGS. 1A and 1C, wherein the horizontal axis of FIG. 1C is the side length of the electroluminescent layer (for example, side length E1), and the vertical axis is the above-mentioned single area ratio, that is, the area ratio η1, η2, or η3. In the embodiment shown in FIG. 1A, the areas of the first to third overlapping regions can be substantially equal to each other, and the areas of the first to third pixel regions can also be substantially equal to each other, so the area The ratios η1, η2, and η3 are also substantially equal to each other. In other words, the curve C1 shown in FIG. 1C may represent the area ratio η1, η2, or η3.

It should be noted that the relationship between the side length and the area ratio represented by the curve C1 is based on the condition that the distance D11 is approximately 3 microns (μm) and the distance D12 is approximately 6 microns. In order to maintain a certain yield, the distance D11 will be limited by the error caused by the lithography and etching process, so the distance D11 will have a minimum limit, and the current existing lithography and etching process can achieve a distance of about 3 microns D11 . From the perspective of FIG. 1C, when the side length of the electroluminescent layer (eg, side length E1) is less than 25 microns, the area ratio (eg, area ratio η1, η2, or η3) will be less than or equal to 70%.

1A and 1B, the control substrate 110 further includes a plurality of control elements 114, a flat layer 112, a substrate 115 and a plurality of contact windows 111v. The control elements 114 are located between the flat layer 112 and the substrate 115, and the flat layer 112 is disposed on the substrate 115 and has a surface 112s and a plurality of through holes 112v, wherein the through holes 112v extend from the surface 112s to the control elements 114 . The contact windows 111v are formed in the through holes 112v, respectively, and each contact window 111v connects one of the control elements 114 and one of the metal electrodes, such as the first anode 111r, the second anode 111g, or the third anode 111b. In this way, using the contact window 111v, the control elements 114 can be electrically connected to the metal electrodes such as the first anode 111r, the second anode 111g, and the third anode 111b, respectively, so that the control elements 114 can control the current input to the metal electrodes.

A part of each contact window 111v is exposed on the surface 112s. For example, the top of each contact window 111v will be exposed on the surface 112s, as shown in FIGS. 1A and 1B. The contact window 111v, the first anode 111r, the second anode 111g, and the third anode 111b can all be formed by lithography and etching of the same metal layer. In other words, the constituent materials of the four of the contact window 111v, the first anode 111r, the second anode 111g, and the third anode 111b may be the same as each other. Each contact window 111v does not fill the through hole 112v, so each contact window 111v is hollow and has an opening exposed on the surface 112s (not shown in FIG. 1A and not marked in FIG. 1B).

When the ambient light L1 is incident on the contact window 111v, the ambient light L1 is trapped by the contact window 111v and is difficult to reflect back. In other words, these contact windows 111v do not substantially reflect the ambient light L1, so even if a part of each contact window 111v is exposed on the surface 112s, the above-mentioned area ratios η1, η2, and η3 need not consider the contact window 111v, which is the above average ratio η is established under the condition of ignoring the contact window 111v. In addition, the color of the flat layer 112 may be black, so that the flat layer 112 not only becomes opaque, but also absorbs ambient light L1 to effectively reduce the reflection of ambient light L1.

In this embodiment, each control element 114 may be a transistor, such as a thin film transistor (Thin Film Transistor, TFT). Specifically, each control element 114 may include a gate 114g, a semiconductor layer 114c, a source 114s, and a drain 114d. The gate electrode 114g, the source electrode 114s, and the drain electrode 114d can all be metal layers, wherein the source electrode 114s and the drain electrode 114d can both be formed by lithography and etching of the same metal layer. In addition, the control substrate 110 may further include insulating layers 113a, 113b, and 113c, wherein the insulating layers 113a, 113b, and 113c may be oxide layers or nitride layers, such as silicon oxide or silicon nitride.

The semiconductor layer 114c of these control elements 114 is formed on the substrate 115 and is covered by the insulating layer 113a. The gate 114g is formed on the insulating layer 113a and is covered by the insulating layer 113b. These gates 114g can be sandwiched between the insulating layers 113a and 113b, and in the same control element 114, the gates 114g and the semiconductor layer 114c overlap each other, that is, the gates 114g can be aligned with the semiconductor layer 114c, wherein the insulating layer 113a is sandwiched between the gate electrode 114g and the semiconductor layer 114c, so that the gate electrode 114g and the semiconductor layer 114c will not contact each other, that is, the gate electrode 114g and the semiconductor layer 114c will not be electrically connected directly. A part of the source 114s and the drain 114d of these control elements 114 are formed on the insulating layer 113b, and the other parts of the source 114s and the drain 114d pass through the insulating layers 113a and 113b and are connected to the semiconductor layer 114c .

Since the gate 114g and the semiconductor layer 114c overlap each other, and the insulating layer 113a is sandwiched between the gate 114g and the semiconductor layer 114c, a capacitance is formed between the gate 114g and the semiconductor layer 114c, and between the gate 114g and the semiconductor layer 114c The electric field generated between the semiconductor layers 114c can change the carrier distribution in the semiconductor layer 114c, thereby allowing the semiconductor layer 114c to form a channel that can electrically connect the source 114s and the drain 114d to each other. It can be seen that the control element 114 can also be a field-effect transistor (FET), and can control the current input to the first anode 111r, the second anode 111g, and the third anode 111b.

It should be noted that, in the embodiment shown in FIG. 1B, each control element 114 may be a top-gate transistor. That is, in the same control element 114, the gate 114g is located between the upper half of both the source 114s and the drain 114d and the semiconductor layer 114c. However, in other embodiments, the control element 114 may also be a bottom-gate transistor, that is, the semiconductor layer 114c may be located between both the source 114s and the drain 114d and the gate 114g. Therefore, the control element 114 is not limited to the top gate transistor as shown in FIG. 1B.

Specifically, the substrate 115 shown in FIG. 1B may have a three-layer structure, that is, the substrate 115 may include a support plate 115a, a connection layer 115b, and a carrier plate 115c. In this embodiment, the constituent materials of both the support plate 115a and the carrier plate 115c may be the same. For example, both the support plate 115a and the carrier plate 115c may be flexible substrates or rigid substrates, wherein the flexible substrates may be made of polymer materials, and the rigid substrates For example, a glass plate or a silicon substrate.

In other embodiments, the constituent materials of both the support plate 115a and the carrier plate 115c may be different from each other. For example, the carrier plate 115c may be the above rigid substrate, and the support plate 115a may be the above flexible substrate. The connection layer 115b may be a polymer material layer, and its constituent material is, for example, polyethylene terephthalate (Polyethylene Terephthalate (PET), polyimide (Polyimide, PI), or triacetylcellulose (TAC) . In addition, it should be noted that, in the embodiment shown in FIG. 1B, the substrate 115 has a multi-layer structure, but in other embodiments, the substrate 115 may also be a single-layer plate material, for example, the substrate 115 may be a single glass plate Or silicon substrate. Therefore, the substrate 115 shown in FIG. 1B is for illustration only, and is not intended to limit the substrate 115 to include a multi-layer structure.

The display panel 100 may further include an encapsulation layer 140 disposed between the opposite electrode 124 and the light-shielding pattern 130. The encapsulation layer 140 may be a thin film encapsulation (Thin Film Encapsulation, TFE), and can insulate the external moisture from intruding into these electroluminescent layers (such as the first electroluminescent layer 122r, the second electroluminescent layer 122g and the third electroluminescent layer) The electroluminescent layer 122b), thereby preventing the electroluminescent layer from failing due to contact with moisture. The encapsulation layer 140 may have a multi-layer structure. Taking FIG. 1B as an example, the encapsulation layer 140 includes two inorganic layers 141 and 143 and an organic layer 142, wherein the organic layer 142 is sandwiched between the two inorganic layers 141 and 143.

The inorganic layer 141 is disposed on the counter electrode 124 and can cover and contact the counter electrode 124. The inorganic layer 143 is disposed on the organic layer 142 and between the organic layer 142 and the light-shielding pattern 130. The constituent materials of both the inorganic layers 141 and 143 may be nitrides or oxides, such as silicon nitride or aluminum oxide, and the constituent materials of both the inorganic layers 141 and 143 may be the same as or different from each other. The constituent material of the organic layer 142 may be a polymer material, such as acrylic resin, epoxy, or silicon oxycarbide.

The display panel 100 may further include a plurality of filter layers 140r, 140g and 140b, a counter substrate 160 and a protective layer 150, wherein the protective layer 150 is formed between the counter substrate 160 and the filter layers 140r, 140g and 140b, and The light shielding pattern 130, these filter layers 140r, 140g, and 140b are interposed between the protective layer 150 and the encapsulation layer 140. The filter layers 140r, 140g, and 140b are different from each other, and can allow light of different colors to penetrate. When the first electroluminescent layer 122r, the second electroluminescent layer 122g, and the third electroluminescent layer 122b emit red light LR1, green light LG1, and blue light LB1, respectively, the filter layer 140r can allow the red light LR1 to penetrate, The filter layer 140g can allow the green light LG1 to penetrate, and the filter layer 140b can allow the blue light LB1 to penetrate.

Both the counter substrate 160 and the protective layer 150 are transparent. For example, the counter substrate 160 may be a glass plate, that is, the counter substrate 160 may be a rigid base material. The constituent material of the protective layer 150 may be transparent epoxy resin or acrylic resin. Therefore, the red light LR1, green light LG1, and blue light LB1 emitted from the filter layers 140r, 140g, and 140b can penetrate the opposite substrate 160 and the protective layer 150, so that the display panel 100 can present an image on the surface of the opposite substrate 160 . In addition, the counter substrate 160 may also be a flexible substrate, such as a transparent and flexible polymer substrate, and its constituent material may be polyethylene terephthalate (PET) or polyimide (PI ). When the counter substrate 160, the support plate 115a, and the carrier plate 115c are all flexible substrates, the display panel 100 can have flexibility, so that a flexible display can be manufactured.

The two adjacent filter layers (for example, the filter layers 140r and 140g) and the light shielding pattern 130 may partially overlap each other. Taking FIG. 1B as an example, the peripheral portions of two adjacent filter layers 140r and 140g overlap each other, and the peripheral portions partially cover the light shielding pattern 130 so that the adjacent two filter layers 140r, 140g and the light shielding pattern 130 partially overlapping. Similarly, the peripheral portions of the two adjacent filter layers 140g and 140b overlap each other, and the peripheral portions partially cover the light shielding pattern 130, so the adjacent two filter layers 140g, 140b and the light shielding pattern 130 partially overlap each other. Since the light-shielding pattern 130 partially overlaps with two adjacent filter layers, the overlapped portion of the two filter layers has a good light absorption capability, which improves the absorption of ambient light L1 by the light-shielding pattern 130, thereby effectively reducing the ambient light L1 reflection.

In addition, the display panel 100 may have a touch function. Specifically, the display panel 100 may further include a plurality of first touch electrodes 171, a plurality of second touch electrodes 172, and an insulating pattern 173, wherein the first touch electrodes 171, the second touch electrodes 172, and the insulation The patterns 173 are all disposed between the encapsulation layer 140 and the light-shielding pattern 130 and overlap with the light-shielding pattern 130, and the insulating pattern 173 is further disposed between the first touch electrodes 171 and the second touch electrodes 172. When an object, such as a finger or a stylus, touches the outer plane of the opposite substrate 160 and moves on the outer plane of the opposite substrate 160, the first touch electrodes 171 and the second touch electrodes 172 can sense Measure the change of capacitance, and then determine the location of the object. As such, the display panel 100 may have a touch function.

The size and shape of the second anode 211g and the third anode 211b, and the size of the first anode 311r is significantly larger than the size of the first anode 211r, the size of the second anode 311g is significantly larger than the size of the second anode 211g, and the third The size of the anode 311b is significantly larger than the size of the third anode 211b.

Since Table (3) is measured in the dark state of the display panels 200 and 300, both display panels 200 and 300 have low brightness (L*) and chromaticity (a* and b*). From the above table (3), compared to the display panel 300 of the comparative example, the display panel 200 of the present embodiment has lower brightness (L*) and color difference (Δa*b*). In addition, the chromaticity a* of both display panels 200 and 300 are negative, and the chromaticity b* of both are positive, so the coordinates of the colors of the display panels 200 and 300 in the CIELAB color space will be slightly biased Green and yellow.
