[0035] The implementation method is described with reference to the accompanying drawings.

[0036] The disclosed content is merely an example, and those skilled in the art can readily conceive of appropriate modifications that maintain the spirit of the invention, which are naturally included within the scope of this invention. Furthermore, to make the description clearer, there are instances where the width, thickness, shape, etc., of various parts are schematically shown in the drawings compared to the actual form; however, this is merely an example and does not limit the interpretation of the invention. Additionally, in this specification and the various figures, sometimes the same reference numerals are used for components that perform the same or similar functions as those described with respect to previously presented figures, and repetitive detailed descriptions are appropriately omitted.

[0037] It should be noted that, for ease of understanding, the X, Y, and Z axes are shown as mutually orthogonal in the diagram. The direction along the X-axis is called the first direction X, the direction along the Y-axis is called the second direction Y, and the direction along the Z-axis is called the third direction Z. Viewing various elements parallel to the third direction Z is called a top view. It should be noted that terms such as "above," "above," "between," and "opposite," which refer to the positional relationship between two or more constituent elements, include not only cases where the two or more constituent elements are in direct contact, but also cases where they are separated by gaps or other constituent elements. Furthermore, the positive direction of the Z-axis is referred to as "above" or "above."

[0038] The display device described in this embodiment is an organic electroluminescent display device that incorporates an organic light-emitting diode (OLED) as a display element, and can be mounted on various electronic devices such as televisions, personal computers, in-vehicle devices, tablet terminals, smartphones, mobile phone terminals, and wearable terminals.

[0039] Figure 1 This is a diagram illustrating an example configuration of a display device DSP.

[0040] The display device DSP has a display area DA for displaying images and a peripheral area SA surrounding the display area DA on an insulating substrate 10. The substrate 10 can be a glass substrate or a flexible resin substrate.

[0041] The display area DA has a plurality of pixels PX arranged in a matrix in the first direction X and the second direction Y. Pixel PX contains a plurality of sub-pixels SP that display different colors. In one example, pixel PX contains a sub-pixel SP1 of a first color, a sub-pixel SP2 of a second color, and a sub-pixel SP3 of a third color. The first color, the second color, and the third color are different colors. Alternatively, pixel PX may contain sub-pixels SP of other colors such as white, either together with or replacing any one of sub-pixels SP1, SP2, and SP3.

[0042] The sub-pixel SP includes a pixel circuit 1 and a display element DE driven by the pixel circuit 1. The pixel circuit 1 includes a pixel switch 2, a driving transistor 3, and a capacitor 4. The pixel switch 2 and the driving transistor 3 are switching elements made of, for example, thin-film transistors.

[0043] The gate electrode of pixel switch 2 is connected to scan line GL. One of the source and drain electrodes of pixel switch 2 is connected to signal line SL, and the other is connected to the gate electrode of driving transistor 3 and capacitor 4. In driving transistor 3, one of the source and drain electrodes is connected to power line PL and capacitor 4, and the other is connected to display element DE. In the illustrated example, scan line GL and power line PL extend in the first direction X, and signal line SL extends in the second direction Y.

[0044] It should be noted that the structure of pixel circuit 1 is not limited to the example shown in the figure. For example, pixel circuit 1 can also have more thin-film transistors and capacitors.

[0045] Display elements (DEs) include, for example, organic light-emitting diodes (OLEDs) that serve as light-emitting elements, and there are also cases called organic EL elements.

[0046] Figure 2 This is a diagram showing an example of the layout of the subpixels SP1, SP2, SP3 that make up a pixel PX.

[0047] In the illustrated example, in pixel PX, sub-pixel SP1 extends in the second direction Y, sub-pixels SP2 and SP3 are arranged in the second direction Y, sub-pixels SP1 and SP2 are arranged in the first direction X, and sub-pixels SP1 and SP3 are arranged in the first direction X.

[0048] Subpixels SP1, SP2, and SP3 are display elements DE1, DE2, and DE3, respectively. Display elements DE1, DE2, and DE3 are each surrounded by ribs RB. In other words, the ribs RB are formed into a grid shape with openings AP1, AP2, and AP3 at subpixels SP1, SP2, and SP3, respectively.

[0049] In the example shown, the area of ​​opening AP1 is larger than the area of ​​opening AP2, and also larger than the area of ​​opening AP3. It should be noted that the relationship between the shapes and areas of openings AP1, AP2, and AP3, and the layout of subpixels SP1, SP2, and SP3, is not limited to the example shown.

[0050] Figure 3 This is a diagram used to illustrate a structural example of pixel PX.

[0051] In sub-pixel SP1, display element DE1 includes a lower electrode LE1, an organic layer OR1, an upper electrode UE1, and an upper cover layer CP1. The organic layer OR1, which includes the light-emitting layer EM1, is disposed between the lower electrode LE1 and the upper electrode UE1. The upper cover layer CP1 is disposed on top of the upper electrode UE1.

[0052] In sub-pixel SP2, display element DE2 includes a lower electrode LE2, an organic layer OR2, an upper electrode UE2, and an upper cover layer CP2. The organic layer OR2, which includes the light-emitting layer EM2, is disposed between the lower electrode LE2 and the upper electrode UE2. The upper cover layer CP2 is disposed on top of the upper electrode UE2.

[0053] In sub-pixel SP3, display element DE3 includes a lower electrode LE3, an organic layer OR3, an upper electrode UE3, and an upper cover layer CP3. The organic layer OR3, which includes the light-emitting layer EM3, is disposed between the lower electrode LE3 and the upper electrode UE3. The upper cover layer CP3 is disposed on top of the upper electrode UE3.

[0054] The lower electrodes LE1, LE2, and LE3 are respectively equivalent to... Figure 1 The driving transistor 3 of the pixel circuit 1 shown is electrically connected to the anode. The lower electrodes LE1, LE2, and LE3 are, for example, multilayers comprising a transparent layer formed of an oxide conductive material such as indium tin oxide (ITO) and a reflective layer formed of a metallic material such as silver.

[0055] The upper electrodes UE1, UE2, and UE3 can be formed individually or as a common electrode spanning sub-pixels SP1, SP2, and SP3, equivalent to a cathode. The upper electrodes UE1, UE2, and UE3 are formed, for example, from metallic materials such as an alloy of magnesium and silver (MgAg).

[0056] The light-emitting layers EM1, EM2, and EM3 are formed of different materials. In one example, EM1 is formed of a material that emits light in the blue wavelength range, EM2 is formed of a material that emits light in the green wavelength range, and EM3 is formed of a material that emits light in the red wavelength range. That is, display element DE1 is configured to display blue as the first color, display element DE2 is configured to display green as the second color, and display element DE3 is configured to display red as the third color.

[0057] Alternatively, the emitting layer EM1 can be formed of a material that emits light in the green wavelength range, and the emitting layer EM2 can be formed of a material that emits light in the blue wavelength range. That is, the display element DE1 can be configured to display green as the first color, and the display element DE2 can be configured to display blue as the second color.

[0058] In addition, the organic layers OR1, OR2, and OR3, besides the light-emitting layer, also contain multiple functional layers such as 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.

[0059] The topcoat layers CP1, CP2, and CP3 function as optical adjustment layers to improve the extraction efficiency of light emitted from the organic layers OR1, OR2, and OR3, respectively. The topcoat layers CP1, CP2, and CP3 are multilayers of multiple thin films. All the thin films are transparent and have different refractive indices. Alternatively, the topcoat layers CP1, CP2, and CP3 can be omitted.

[0060] Figure 4 This is a top view used to illustrate the composition of Example 1.

[0061] In the display area DA, there are columns of multiple sub-pixels SP1 (or multiple display elements DE1) arranged in the second direction Y, and columns of sub-pixels SP2 and sub-pixels SP3 (or display elements DE2 and DE3) arranged alternately in the second direction Y. In the first direction X, sub-pixels SP1 and sub-pixels SP2 (or display elements DE1 and DE2) are arranged alternately, and sub-pixels SP1 and sub-pixels SP3 (or display elements DE1 and DE3) are arranged alternately.

[0062] The light-shielding layer 20 is configured to overlap with the display area DA when viewed from above. The light-shielding layer 20 has a plurality of openings OP arranged in a matrix in the first direction X and the second direction Y. In the illustrated example, the openings OP extend in the second direction Y and are formed into a rectangular shape.

[0063] Focus on two pixels, PX1 and PX2, which are arranged in the second direction Y among the multiple pixels configured in the display area DA.

[0064] In pixel PX1, the light-shielding layer 20 is disposed between display element DE1 and display element DE2, and is also disposed between display element DE1 and display element DE3, and overlaps with a portion (right portion) of display element DE1, a portion (left portion) of display element DE2 and a portion (left portion) of display element DE3.

[0065] Multiple openings OP include openings OP1 and OP2 arranged in the first direction X. Opening OP1 is located to the left of pixel PX1 and overlaps with another part (left portion) of display element DE1. Opening OP2 is located to the right of pixel PX1 and overlaps with another part (right portion) of display element DE2 and another part (right portion) of display element DE3. That is, the light-shielding layer 20 is formed at pixel PX1 to expose a portion of each of display elements DE1, DE2, and DE3.

[0066] Regarding pixel PX2, similarly to pixel PX1, the light-shielding layer 20 is disposed between display elements DE1 and DE2, and also between display elements DE1 and DE3. The opening OP1 on the left side of pixel PX2 overlaps with a portion of display element DE1, and the opening OP2 on the right side of pixel PX2 overlaps with a portion of display elements DE2 and a portion of display element DE3.

[0067] Figure 5 It is along Figure 4 A schematic cross-sectional view of the DSP display device for the A-B lines.

[0068] A circuit layer 11 is disposed on the substrate 10. The circuit layer 11 includes... Figure 1 The diagram shows various circuits such as pixel circuit 1, scan lines GL, signal lines SL, power lines PL, and various insulating layers.

[0069] Display elements DE1 and DE2 are disposed on circuit layer 11. Display element DE3 (not shown) is also disposed on circuit layer 11. Ribs RB are disposed on circuit layer 11, separating display elements DE1, DE2, and DE3 from each other. Ribs RB are formed, for example, of organic insulating material, but may also be formed of inorganic insulating material.

[0070] The sealing layer 12 covers the display elements DE1, DE2, and DE3. The sealing layer 12 is formed of inorganic insulating materials such as silicon nitride (SiNx), silicon oxide (SiOx), and silicon oxide nitride (SiON).

[0071] A transparent resin layer 13 is disposed on the sealing layer 12. The resin layer 13 is formed to flatten the unevenness caused by the display elements DE1, DE2, and DE3.

[0072] An inorganic insulating layer 14 is disposed on the resin layer 13. The inorganic insulating layer 14 is formed of the same inorganic insulating material as the sealing layer 12.

[0073] A transparent organic insulating layer 15 is located above display elements DE1, DE2, and DE3, and is disposed above the inorganic insulating layer 14. The thickness T2 of the organic insulating layer 15 is greater than the thickness T1 of the resin layer 13 (T1 < T2).

[0074] A light-shielding layer 20 is disposed on the organic insulating layer 15. The light-shielding layer 20 is a laminate having a first layer 21 on the organic insulating layer 15 and a second layer 22 on the first layer 21. The first layer 21 and the second layer 22 are formed of different materials.

[0075] Layer 1 21 is a black layer with extremely low reflectivity over approximately the entire visible light region (visible light range). Layer 1 21 can be a metallic layer or a resin layer containing pigments.

[0076] The second layer 22 functions as a wavelength cutoff layer with extremely low reflectivity within a specific wavelength range in the visible light region. The second layer 22 is a coloring layer colored with the first color in the visible light region. For example, the second layer 22 can be colored with any one of red, green, or blue. Alternatively, the second layer 22 can also be colored with any one of cyan, magenta, or yellow.

[0077] As a suitable combination of layer 1 21 and layer 22, it is desirable to integrate (match) the wavelength range with relatively high reflectivity in the spectral reflectivity of layer 1 21 with the wavelength range with extremely low reflectivity in the spectral reflectivity of layer 22.

[0078] A specific example will be given. If the first layer 21 has a relatively high reflectivity in the blue wavelength range, the reflected light from the first layer 21 will have a blue component. In such a case, it is desirable to use a coloring layer with extremely low reflectivity in the blue wavelength range as the second layer 22, for example, a red coloring layer.

[0079] As another specific example, if the reflected light of the first layer 21 has a magenta component, then as the second layer 22, it is desirable to apply a green coloring layer.

[0080] The organic insulating layer 15 and the light-shielding layer 20 are covered by the covering component CV, indicated by the double-dotted line. The covering component CV includes a transparent protective film, a circular polarizer for preventing reflection, a glass cover, etc.

[0081] Next, we will explain one of the functions of the DSP in the aforementioned display device.

[0082] Regarding the central opening OP shown in the diagram, this opening OP overlaps with the left portion of display element DE1 and the right portion of display element DE2. When display element DE1 is emitting light, ray B1 within the range LV that can pass through the opening OP can be observed. When display element DE2 is emitting light, ray B2 within the range RV that can pass through the opening OP can be observed. In other words, by providing the light-shielding layer 20, the observable range of the light emitted from each of display elements DE1 and DE2 can be limited.

[0083] At an observation position tilted to the left relative to the normal N of the substrate 10, light ray B1, mainly emitted from display element DE1, can be observed through the opening OP. Similarly, at an observation position tilted to the right relative to the normal N, light ray B2, mainly emitted from display element DE2, can be observed through the opening OP. At other openings OP, a portion of the light emitted from each light-emitting element is restricted from passing through.

[0084] Therefore, a user observing the display device DSP from a left-hand oblique direction relative to the normal N can observe the first image as a collection of light rays B1 emitted from multiple light-emitting elements. Similarly, a user observing the display device DSP from a right-hand oblique direction relative to the normal N can observe the second image as a collection of light rays B2 emitted from multiple light-emitting elements. For example, the first and second images are distinct images. In this way, although the display device DSP has a single display area DA, it can display distinct images in two different oblique directions.

[0085] The light-shielding layer 20 used to achieve such light control is a laminate comprising a first layer 21 and a second layer 22, which are formed of different materials. As described above, a combination with appropriate spectral reflectivity is suitable for the first layer 21 and the second layer 22. Therefore, when the display device DSP is used in an environment where external light illuminates it, color distortion caused by undesirable reflections from the light-shielding layer 20 can be suppressed. Thus, the display quality of the image displayed in the display area DA can be improved.

[0086] Next, we will explain several variations that constitute Example 1.

[0087] Figure 6 This is a schematic sectional view of variation 1.

[0088] Figure 6 The modified example 1 shown is the same as Figure 5 Compared to the example shown, the difference lies in the fact that the light-shielding layer 20 has multiple coloring layers. Regarding the other constituent elements in Modified Example 1, compared to... Figure 5The constituent elements shown are the same, and the same labels are used as shown in the attached drawings, with explanations omitted.

[0089] The light-shielding layer 20 is a laminate comprising a first layer 21 above the organic insulating layer 15, a second layer 22 above the first layer 21, and a third layer 23 above the second layer 22. The first layer 21, the second layer 22, and the third layer 23 are formed of different materials.

[0090] For example, layer 21 is a black layer with extremely low reflectivity over approximately the entire visible light region. Layer 22 is a colored layer tinted with a first color. Layer 3 is a colored layer tinted with a second color, different from the first color. The combination of layers 22 and 33 is appropriately determined based on the spectral reflectivity of layer 21.

[0091] As an example, if the reflected light of the first layer 21 has a magenta component, it is desirable to use a red coloring layer as the second layer 22 and a blue coloring layer as the third layer 23.

[0092] By configuring the light-shielding layer 20 as a stack of a black layer and multiple colored layers, unwanted external light reflection caused by the light-shielding layer 20 can be suppressed. Therefore, in Modification 1, the same effect as described above can also be obtained.

[0093] Figure 7 This is a schematic sectional view of variation 2.

[0094] Figure 7 The modified example 2 shown is the same as Figure 5 Compared to the example shown, the difference lies in the fact that the light-shielding layer 20 replaces the black layer and has multiple colored layers. Regarding the other constituent elements in variant example 2, they are similar to... Figure 5 The constituent elements shown are the same, and the same labels are used as shown in the attached drawings, with explanations omitted.

[0095] The light-shielding layer 20 is a laminate comprising a first layer 21 above the organic insulating layer 15, a second layer 22 above the first layer 21, and a third layer 23 above the second layer 22. The first layer 21, the second layer 22, and the third layer 23 are colored layers formed of different materials.

[0096] Layer 1 21 is a coloring layer tinted with a first color. Layer 22 is a coloring layer tinted with a second color, different from the first color. Layer 3 23 is a coloring layer tinted with a third color, different from both the first and second colors. For example, layer 1 21 is a blue coloring layer, layer 22 is a green coloring layer, and layer 3 23 is a red coloring layer. This combination of blue, green, and red coloring layers has extremely low reflectivity across almost the entire visible light region. Therefore, the light-shielding layer 20 in Modified Example 2 functions as a light-shielding layer equivalent to the black layer. Furthermore, the stacking order of the coloring layers is not limited to the example shown here.

[0097] In this variation example 2, the same effect as described above can also be obtained.

[0098] Next, we will explain configuration example 2. In the configuration examples described below, there are cases where the same reference numerals are used for the same constituent elements as those described in configuration example 1 above, and the description is omitted.

[0099] Figure 8 This is a top view used to illustrate the composition of Example 2.

[0100] In addition to the light-shielding layer 20 described in Configuration Example 1, Configuration Example 2 also includes a light-shielding layer 30. It should be noted that... Figure 8 The illustration of the light-shielding layer 20 is omitted. The shape of the light-shielding layer 20 is as shown in the reference. Figure 4 The shape described.

[0101] The light-shielding layer 30 is configured to overlap with the display area DA when viewed from above. The light-shielding layer 30 is formed in a lattice shape that overlaps with the rib RB. That is, the light-shielding layer 30 has a shape that overlaps with the reference area. Figure 2 The openings AP1, AP2, and AP3 of the ribs RB overlap. The openings of the display elements DE1, DE2, and DE3 overlap with the openings of the light-shielding layer 30.

[0102] Figure 9 It is along Figure 8 A schematic cross-sectional view of the DSP display device with C-D lines.

[0103] The light-shielding layer 30 is located directly above the rib RB, disposed above the inorganic insulating layer 14, and covered by the organic insulating layer 15. A portion of the light-shielding layer 30 overlaps with the opening OP.

[0104] The light-shielding layer 30 is a laminate comprising a fourth layer 31 located above the inorganic insulating layer 14 and a fifth layer 32 located above the fourth layer 31. The fourth layer 31 and the fifth layer 32 are formed of different materials.

[0105] Layer 4, 31, is a black layer with extremely low reflectivity over approximately the entire visible light region. Layer 4, 31 can be a metallic layer or a resin layer containing pigments.

[0106] Layer 5, 32, functions as a wavelength cutoff layer with extremely low reflectivity within a specific wavelength range in the visible light region. Layer 5, 32 is a coloring layer colored with the first color in the visible light region. For example, layer 5, 32 is a coloring layer colored with red, green, blue, cyan, magenta, yellow, etc.

[0107] The appropriate combination of layer 4 (31) and layer 5 (32) is the same as the appropriate combination of layer 1 (21) and layer 22 (22) described in Example 1.

[0108] In Configuration Example 2, which includes such a light-shielding layer 30, compared to Configuration Example 1, the observable range of light emitted from each of the display elements DE1, DE2, and DE3 can be further limited. Furthermore, when viewing the display device DSP from an angle, unwanted reflections in the light-shielding layer 30 can be suppressed. Therefore, the display quality of the image displayed in the display area DA can be improved.

[0109] Furthermore, in the illustrated example, the light-shielding layer 20 is a stack of layers 1 21 and 22, with layers 1 21 and 4 31 formed of the same material, and layers 22 and 5 32 formed of the same material. Therefore, when manufacturing the display device DSP, the amount of material required to form the light-shielding layers 20 and 30 can be limited, thus suppressing the increase in manufacturing costs.

[0110] Next, we will explain several variations that constitute Example 2.

[0111] Figure 10 This is a schematic sectional view of variation 3.

[0112] Figure 10 The variation shown in Example 3 and Figure 9 Compared to the example shown, the difference lies in the fact that the light-shielding layer 30 has multiple coloring layers. Regarding other constituent elements in variant example 3, they are similar to... Figure 9 The constituent elements shown are the same, and the same labels are used as shown in the attached drawings, with explanations omitted.

[0113] The light-shielding layer 30 is a laminate comprising a fourth layer 31 above the inorganic insulating layer 14, a fifth layer 32 above the fourth layer 31, and a sixth layer 33 above the fifth layer 32. The fourth layer 31, the fifth layer 32, and the sixth layer 33 are formed of different materials.

[0114] For example, layer 4, 31, is a black layer with extremely low reflectivity over approximately the entire visible light region. Layer 5, 32, is a colored layer tinted with a first color. Layer 6, 33, is a colored layer tinted with a second color, different from the first color. The combination of layers 5, 32, and 6, 33 is appropriately determined based on the spectral reflectivity of layer 4, 31.

[0115] In the illustrated example, the light-shielding layer 20 is a stack of layers 1 21, 22 and 33. Layer 1 21 and 4 31 are formed of the same material, layer 22 and 5 32 are formed of the same material, and layer 33 and 6 33 are formed of the same material.

[0116] In this variation example 3, the same effect as described above can also be obtained.

[0117] Figure 11 This is a schematic sectional view of variation 4.

[0118] Figure 11 The variation shown is 4 and Figure 9 Compared to the example shown, the difference lies in the fact that the light-shielding layer 30 replaces the black layer and has multiple colored layers. Regarding the other constituent elements in variant example 4, they are similar to... Figure 9 The constituent elements shown are the same, and the same labels are used as shown in the attached drawings, with explanations omitted.

[0119] The light-shielding layer 30 is a laminate comprising a fourth layer 31 above the inorganic insulating layer 14, a fifth layer 32 above the fourth layer 31, and a sixth layer 33 above the fifth layer 32. The fourth layer 31, the fifth layer 32, and the sixth layer 33 are colored layers formed of different materials.

[0120] Layer 4, 31, is a coloring layer tinted with the first color. Layer 5, 32, is a coloring layer tinted with the second color, different from the first color. Layer 6, 33, is a coloring layer tinted with the third color, different from both the first and second colors. For example, layer 4, 31, is a blue coloring layer, layer 5, 32, is a green coloring layer, and layer 6, 33, is a red coloring layer. This combination of blue, green, and red coloring layers has extremely low reflectivity across almost the entire visible light spectrum. Therefore, the light-shielding layer 30 in Modified Example 4 functions as a light-shielding layer equivalent to the black layer. It should be noted that the stacking order of the coloring layers is not limited to the example shown here.

[0121] In the illustrated example, the light-shielding layer 20 is a stack of layers 1 21, 22 and 33. Layer 1 21 and 4 31 are formed of the same material, layer 22 and 5 32 are formed of the same material, and layer 33 and 6 33 are formed of the same material.

[0122] In this variation 4, the same effect as described above can also be obtained.

[0123] It should be noted that, in Figures 9 to 11 In the examples shown, the combination of materials constituting the light-shielding layer 30 may also differ from the combination of materials constituting the light-shielding layer 20. For example, the combination may also be different. Figure 9 The light-shielding layer 30 shown and Figure 6 or Figure 7 The light-shielding layer 20 is shown. Alternatively, it can be combined with... Figure 10 The light-shielding layer 30 shown and Figure 5 or Figure 7 The light-shielding layer 20 is shown. Alternatively, it can be combined with... Figure 11 The light-shielding layer 30 shown and Figure 5 or Figure 6 The light-shielding layer 20 is shown.

[0124] Next, we will explain the composition of Example 3.

[0125] Figure 12 This is a top view used to illustrate the composition of Example 3.

[0126] In addition to the light-shielding layer 20 described in Configuration Example 1, Configuration Example 3 also includes several color filters CF1, CF2, and CF3. It should be noted that... Figure 12 The illustration of the light-shielding layer 20 is omitted. The shape of the light-shielding layer 20 is shown in the figure below. Figure 4 Describe that shape.

[0127] The color filter CF1 is configured to overlap with the display element DE1 when viewed from above. When the display element DE1 is configured to display a first color, the color filter CF1 is colored with the first color (e.g., blue).

[0128] The color filter CF2 is configured to overlap with the display element DE2 when viewed from above. When the display element DE2 is configured to display a second color, the color filter CF2 is colored with the second color (e.g., green).

[0129] The color filter CF3 is configured to overlap with the display element DE3 when viewed from above. When the display element DE3 is configured to display a third color, the color filter CF3 is colored with the third color (e.g., red).

[0130] In the illustrated example, color filters CF1, CF2, and CF3 are separated from each other, but two or all three of them can also be connected to each other. The edges of each color filter CF1, CF2, and CF3 overlap with rib RB over the entire circumference when viewed from above.

[0131] Figure 13 It is along Figure 12 A schematic cross-sectional view of the DSP display device with E-F lines.

[0132] Color filter CF1 is located directly above display element DE1, disposed on inorganic insulating layer 14, and covered by organic insulating layer 15. Color filter CF2 is located directly above display element DE2, disposed on inorganic insulating layer 14, and covered by organic insulating layer 15. Although not shown, color filter CF3 is located directly above display element DE3, disposed on organic insulating layer 14, and covered by organic insulating layer 15. A portion of each of color filters CF1, CF2, and CF3 overlaps with opening OP.

[0133] Regarding the light-shielding layer 20, it could also be... Figure 5 The stack shown, consisting of a first layer 21 as a black layer and a second layer 22 as a coloring layer, can also be... Figure 6 The laminate shown, consisting of a first layer 21 as a black layer and a second layer 22 and a third layer 23 as coloring layers, can also be... Figure 7 The stack shown consists of layer 1 21, layer 22, and layer 3 23, which serve as coloring layers.

[0134] In Configuration Example 3, which includes color filters CF1, CF2, and CF3, a portion of the external light directed towards the display device DSP is absorbed by the color filters CF1, CF2, and CF3. On the other hand, light of the first color emitted from display element DE1 passes through color filter CF1. Similarly, light of the second color emitted from display element DE2 passes through color filter CF2, and light of the third color emitted from display element DE3 passes through color filter CF3. Therefore, unwanted reflections of external light can be suppressed, improving the display quality of the image displayed in display area DA. Furthermore, the circular polarizer used for anti-reflection can be omitted from the cover member CV.

[0135] Next, we will explain the composition of Example 4.

[0136] Figure 14 This is a top view used to illustrate the composition of Example 4.

[0137] In addition to the light-shielding layer 20 described in Configuration Example 1 and the color filters CF1, CF2, and CF3 described in Configuration Example 3, Configuration Example 4 also includes a light-shielding layer 30. It should be noted that in... Figure 14 The illustration of the light-shielding layer 20 is omitted. The shape of the light-shielding layer 20 is shown in the figure below. Figure 4 Describe that shape.

[0138] The light-shielding layer 30 is configured to overlap with the display area DA when viewed from above. The light-shielding layer 30 is formed in a lattice shape that overlaps with the rib RB. That is, the light-shielding layer 30 has a shape that overlaps with the reference area. Figure 2The openings AP1, AP2, and AP3 of the rib RB are described as overlapping openings.

[0139] In addition, the light-shielding layer 30 is disposed between color filter CF1 and color filter CF2, between color filter CF3 and color filter CF1, and between color filter CF3 and color filter CF2.

[0140] Display element DE1 overlaps with the opening of the light-shielding layer 30 and with the color filter CF1. Display element DE2 overlaps with the opening of the light-shielding layer 30 and with the color filter CF2. Display element DE3 overlaps with the opening of the light-shielding layer 30 and with the color filter CF3.

[0141] When viewed from above, the edges of color filters CF1, CF2, and CF3 overlap with the light-shielding layer 30 over the entire circumference.

[0142] Figure 15 It is along Figure 14 A schematic cross-sectional view of the DSP display device with G-H lines.

[0143] The light-shielding layer 30 is located directly above the rib RB, disposed above the inorganic insulating layer 14, and covered by the organic insulating layer 15. A portion of the light-shielding layer 30 overlaps with the opening OP.

[0144] Regarding the light-shielding layer 30, it can be... Figure 9 The stack shown, consisting of layer 4 (31) as the black layer and layer 5 (32) as the color layer, can also be... Figure 10 The laminate shown, consisting of layer 4 (31) as the black layer and layers 5 (32) and 6 (33) as coloring layers, can also be... Figure 11 The stack shown consists of layers 4 (31), 5 (32), and 6 (33) as coloring layers.

[0145] Additionally, regarding the light-shielding layer 20, it could be... Figure 5 The stack shown, consisting of a first layer 21 as a black layer and a second layer 22 as a coloring layer, can also be... Figure 6 The laminate shown, consisting of a first layer 21 as a black layer and a second layer 22 and a third layer 23 as coloring layers, can also be... Figure 7 The stack shown consists of layer 1 21, layer 22, and layer 3 23, which serve as coloring layers.

[0146] Color filter CF1 is located directly above display element DE1, disposed on inorganic insulating layer 14, and covered by organic insulating layer 15. Color filter CF2 is located directly above display element DE2, disposed on inorganic insulating layer 14, and covered by organic insulating layer 15. Although not shown, color filter CF3 is located directly above display element DE3, disposed on inorganic insulating layer 14, and covered by organic insulating layer 15. A portion of each of color filters CF1, CF2, and CF3 overlaps with opening OP. The edges of each of color filters CF1, CF2, and CF3 overlap with light-shielding layer 30.

[0147] In this configuration example 4, the same effect as in configuration example 2 with the light-shielding layer 30 can be obtained, and the same effect as in configuration example 3 with the color filters CF1, CF2, and CF3 can also be obtained.

[0148] Next, we will explain the composition of Example 5.

[0149] Figure 16 This is a schematic sectional view that constitutes Example 5.

[0150] Figure 16 Example 5 shown Figure 15 Compared to the configuration example 4 shown, the difference lies in the fact that a stack of color filters CF1, CF2, and CF3 is provided in the area overlapping with the rib RB, replacing the light-shielding layer 30.

[0151] Color filter CF3 is located directly above display element DE3 (not shown), disposed on inorganic insulating layer 14, and extends further above rib RB. Color filter CF2 is located directly above display element DE2, disposed on inorganic insulating layer 14. Color filter CF2 extends further above rib RB, disposed above color filter CF3. Color filter CF1 is located directly above display element DE1, disposed on inorganic insulating layer 14. Color filter CF1 extends further above rib RB, disposed above color filter CF2. In other words, color filters CF3, CF2, and CF1 are stacked sequentially above rib RB. Furthermore, the stacking order of color filters CF1, CF2, and CF3 is not limited to the example shown.

[0152] Color filter CF1 is colored with the first color (e.g., blue). Color filter CF2 is colored with the second color (e.g., green). Color filter CF3 is colored with the third color (e.g., red).

[0153] With reference Figure 11Similarly, in the illustrated variation 4, the combination of the blue, green, and red coloring layers has extremely low reflectivity across almost the entire visible light region. Therefore, the stack of color filters CF1, CF2, and CF3 formed directly above the rib RB functions as a light-shielding layer equivalent to the black layer.

[0154] In addition, regarding the light-shielding layer 20, it can be Figure 5 The stack shown, consisting of a first layer 21 as a black layer and a second layer 22 as a coloring layer, can also be... Figure 6 The laminate shown, consisting of a first layer 21 as a black layer and a second layer 22 and a third layer 23 as coloring layers, can also be... Figure 7 The stack shown consists of layer 1 21, layer 22, and layer 3 23, which serve as coloring layers.

[0155] In this configuration example 5, the aforementioned effects can be achieved, and light control equivalent to that of the light-shielding layer 30 can be realized through the stack of color filters CF1, CF2, and CF3. Furthermore, since the light-shielding layer 30 is omitted, the material used to form it can be reduced, thereby lowering manufacturing costs.

[0156] Next, several common variations in Examples 1 to 5 will be explained. In each variation, the display element DE1 of sub-pixel SP1, the display element DE2 of sub-pixel SP2, the display element DE3 of sub-pixel SP3, and the light-shielding layer 20 are shown, while the illustrations of other constituent elements are omitted.

[0157] Figure 17 This is a top view used to illustrate variation 1.

[0158] In the second direction Y of the display area DA, sub-pixels SP1, SP2, and SP3 (or display elements DE1, DE2, and DE3) are arranged sequentially. Furthermore, in the first direction X, sub-pixels SP1 and SP2 (or display elements DE1 and DE2) are arranged alternately, and sub-pixels SP1 and SP3 (or display elements DE1 and DE3) are also arranged alternately.

[0159] Focus on two pixels, PX1 and PX2, which are arranged in the second direction Y among the multiple pixels configured in the display area DA.

[0160] Display element DE1 of pixel PX1, and display elements DE2 and DE3 of pixel PX2 are arranged in the second direction Y.

[0161] In pixel PX1, the light-shielding layer 20 overlaps with a portion (right portion) of display element DE1, a portion (left portion) of display element DE2, and a portion (left portion) of display element DE3. Opening OP1 is located on the left side of pixel PX1 and overlaps with another portion (left portion) of display element DE1. Opening OP2 is located on the right side of pixel PX1 and overlaps with another portion (right portion) of display element DE2 and another portion (right portion) of display element DE3.

[0162] In pixel PX2, the light-blocking layer 20 overlaps with a portion (left portion) of display element DE1, a portion (right portion) of display element DE2, and a portion (right portion) of display element DE3. Opening OP1 is located on the right side of pixel PX2 and overlaps with another portion (right portion) of display element DE1. Opening OP2 is located on the left side of pixel PX2 and overlaps with another portion (left portion) of display element DE2 and another portion (left portion) of display element DE3.

[0163] Figure 18 This is a top view used to illustrate variation 2.

[0164] In the second direction Y of the display area DA, multiple sub-pixels SP1 (or multiple display elements DE1) are arranged in the second direction Y. In addition, sub-pixels SP2 and SP3 (or display elements DE2 and DE3) are arranged alternately. In addition, in the first direction X, sub-pixels SP1 and SP2 (or display elements DE1 and DE2) are arranged alternately.

[0165] Focus on two pixels, PX1 and PX2, which are arranged in the second direction Y among the multiple pixels configured in the display area DA.

[0166] Display elements DE1 of pixel PX1 and DE1 of pixel PX2 are arranged in the second direction Y. Display elements DE2 and DE3 of pixel PX1 and display elements DE2 and DE3 of pixel PX2 are arranged in the second direction Y.

[0167] In pixel PX1, the light-shielding layer 20 overlaps with a portion (right portion) of display element DE1, a portion (left portion) of display element DE2, and a portion (left portion) of display element DE3. Opening OP1 is located on the left side of pixel PX1 and overlaps with another portion (left portion) of display element DE1. Opening OP2 is located on the right side of pixel PX1 and overlaps with another portion (right portion) of display element DE2 and another portion (right portion) of display element DE3.

[0168] In pixel PX2, the light-shielding layer 20 overlaps with a portion (left portion) of display element DE1, a portion (right portion) of display element DE2, and a portion (right portion) of display element DE3. Opening OP3 separates from openings OP1 and OP2 and is located approximately in the center of pixel PX2. Opening OP3 overlaps with another portion (right portion) of display element DE1, another portion (left portion) of display element DE2, and another portion (left portion) of display element DE3.

[0169] In variations 1 and 2, a user observing the display device DSP from a left-hand oblique direction relative to the normal N can observe the first image as a collection of light rays emitted from display element DE1 of pixel PX1, and display elements DE2 and DE3 of pixel PX2. Conversely, a user observing the display device DSP from a right-hand oblique direction relative to the normal N can observe the second image as a collection of light rays emitted from display elements DE2 and DE3 of pixel PX1, and display element DE1 of pixel PX2.

[0170] These variations 1 and 2 can be applied to any of the above-described configuration examples 1 to 5.

[0171] Next, we will explain the composition of Example 6.

[0172] Figure 19 This is a top view used to illustrate the composition of Example 6.

[0173] Figure 19 Example 6 shown Figure 4 Compared to the illustrated configuration example 1, the difference lies in the inclusion of multiple lenses 40. The lenses 40 are disposed within the opening OP formed in the light-shielding layer 20. In the illustrated example, the multiple lenses 40 extend in the second direction Y and are arranged at intervals in the first direction X. The width of the lenses 40 along the first direction X is greater than the width of the opening OP along the first direction X. The edges of the lenses 40 along the second direction Y overlap with the light-shielding layer 20.

[0174] Figure 20 It is along Figure 19 A schematic cross-sectional view of the DSP display device with I-J lines.

[0175] Lens 40 is disposed on organic insulating layer 15 and overlaps with opening OP. The edge of lens 40 is located on light-shielding layer 20. As shown, lens 40 is a plano-convex lens having a plane in contact with organic insulating layer 15 and a convex surface on the opposite side of the plane.

[0176] The low refractive index layer 50 is formed of a material having a refractive index lower than that of the lens 40. The low refractive index layer 50 is disposed on the light-shielding layer 20, covering the edge of the lens 40 and exposing the top of the lens 40.

[0177] The dotted-dotted line indicates that the cover member CV covers the lens 40 and the low-refractive-index layer 50. When the cover member CV is, for example, a circular polarizer, the lens 40 is covered by the adhesive of the circular polarizer. When the difference between the refractive index of the adhesive and the refractive index of the lens 40 is small, the refractive effect of the lens 40 on light traveling in the oblique direction cannot be sufficiently obtained. Therefore, it is desirable that the edge of the lens 40 be covered by the low-refractive-index layer 50.

[0178] For details regarding the light-shielding layer 20, as explained in Example 1, it can be... Figure 5 The stack shown, consisting of a first layer 21 as a black layer and a second layer 22 as a coloring layer, can also be...

Figure 7 The stack shown consists of layer 1 21, layer 22, and layer 3 23, which serve as coloring layers.

[0179] In this configuration example 6, the same effect as in configuration example 1 above can be obtained.

[0180] Next, we will explain the composition of Example 7.

[0181] Figure 21 This is a schematic sectional view that constitutes Example 7.

[0182] Figure 21 The configuration example shown in Example 7 and Figure 20 Compared to the configuration example 6 shown, the difference lies in the fact that it includes a light-shielding layer 30 in addition to the light-shielding layer 20. Regarding the planar shape of the light-shielding layer 30, it is as shown in the reference... Figure 8 The shape is as described. Lens 40 overlaps with a portion of the light-shielding layer 30.

[0183] Details regarding the light-shielding layer 30, as explained in Example 2, may include...

Figure 11 The stack shown consists of layers 4 (31), 5 (32), and 6 (33) as coloring layers.

[0184] In this configuration example 7, the same effect as described above can also be obtained.

[0185] Next, we will explain the composition of Example 8.

[0186] Figure 22 This is a sectional view used to illustrate the composition of Example 8.

[0187] Figure 22 Example 8 and the configuration shown Figure 20 Compared to the configuration example 6 shown, the difference lies in the fact that it includes several color filters CF1, CF2, and CF3 in addition to the light-shielding layer 20. The arrangement of the color filters CF1, CF2, and CF3 is shown in, for example, reference [reference needed]. Figure 12 As explained above. Details regarding each of the color filters CF1, CF2, and CF3 are as described in Configuration Example 3. Lens 40 overlaps with a portion of each of the color filters CF1, CF2, and CF3.

[0188] In this configuration example 8, the same effect as described above can also be obtained.

[0189] Next, we will explain the composition of Example 9.

[0190] Figure 23 This is a sectional view used to illustrate the composition of Example 9.

[0191] Figure 23 Example 9 and the configuration shown Figure 22 Compared to Configuration Example 8, the difference lies in the presence of the light-shielding layer 30. Details regarding the light-shielding layer 30 are as described in Configuration Example 2.

[0192] In this configuration example 9, the same effect as described above can also be obtained.

[0193] Next, we will explain the composition of Example 10.

[0194] Figure 24 This is a sectional view used to illustrate the composition of Example 10.

[0195] Figure 24 The configuration example 10 shown is the same as Figure 23 Compared to Configuration Example 9, the difference lies in the fact that a stack of color filters CF1, CF2, and CF3 is provided in the region overlapping with rib RB, replacing the light-shielding layer 30. Details regarding the stack of color filters CF1, CF2, and CF3 are as explained in Configuration Example 5.

[0196] In this configuration example 10, the same effect as described above can also be obtained.

[0197] Next, several common variations to Examples 6 to 10 will be explained. In each variation, the display element DE1 of sub-pixel SP1, the display element DE2 of sub-pixel SP2, the display element DE3 of sub-pixel SP3, the light-shielding layer 20, and the lens 40 are illustrated, while illustrations of other constituent elements are omitted.

[0204] Figure 26 This is a top view used to illustrate variation 4.

[0205] In the second direction Y of the display area DA, multiple sub-pixels SP1 (or multiple display elements DE1) are arranged in the second direction Y. In addition, sub-pixels SP2 and SP3 (or display elements DE2 and DE3) are arranged alternately. In addition, in the first direction X, sub-pixels SP1 and SP2 (or display elements DE1 and DE2) are arranged alternately.

[0206] Focus on two pixels, PX1 and PX2, arranged in the second direction Y among the multiple pixels configured in the display area DA. Pixel PX1 is located between two adjacent lenses 40-1 and 40-2 among the multiple lenses 40. Pixel PX2 overlaps with lens 40-3, which is separated from lenses 40-1 and 40-2.

[0207] Display elements DE1 of pixel PX1 and DE1 of pixel PX2 are arranged in the second direction Y. Display elements DE2 and DE3 of pixel PX1 and display elements DE2 and DE3 of pixel PX2 are arranged in the second direction Y.

[0208] In pixel PX1, the light-blocking layer 20 overlaps with a portion (right portion) of display element DE1, a portion (left portion) of display element DE2, and a portion (left portion) of display element DE3.
