[0034] Several implementation modes will be described with reference to the accompanying drawings.

[0035] This disclosure text is merely an example, and appropriate changes that are easily conceivable by those skilled in the art and that maintain the gist of the invention are of course included in the scope of the present invention. In addition, in order to make the description clearer, the width, thickness, shape, etc. of each part of the drawings are sometimes schematically shown, but this is only an example and does not limit the interpretation of the present invention. In addition, in this specification and each figure, sometimes the same reference numerals are assigned to the components that perform the same or similar functions as the components described in the accompanying drawings that have appeared previously, and the repeated detailed descriptions are appropriately omitted.

[0036] Note that in the drawings, for ease of understanding, the X-axis, Y-axis, and Z-axis orthogonal to each other are described as needed. The direction along the X-axis is referred to as the first direction X, the direction along the Y-axis is referred to as the second direction Y, and the direction along the Z-axis is referred to as the third direction Z. Observing various elements parallel to the third direction Z is referred to as a top view.

[0037] The display device of the present embodiment is an organic electroluminescent display device having an organic light-emitting diode (OLED) as a display element, and can be mounted on a television, a personal computer, a vehicle-mounted device, a tablet terminal, a smart phone, a mobile phone terminal, etc.

[0038] Figure 1 It is a diagram showing a configuration example of the display device DSP of one embodiment. The display device DSP has a display panel PNL having a display area DA for displaying an image and a peripheral area SA outside the display area DA on an insulating substrate 10. The substrate 10 can be glass or a flexible resin film.

[0039] In Figure 1 , the shape of the substrate 10 in a top view is a rectangle having a long side parallel to the first direction X. However, the shape of the substrate 10 in a top view is not limited to this example, and for example, it can also be other shapes such as a rectangle having a long side parallel to the second direction Y, a square, a circle, or an ellipse.

[0040] The display area DA includes a plurality of pixels PX arranged in a matrix in the first direction X and the second direction Y. The pixel PX includes a plurality of sub-pixels SP. In one example, the pixel PX includes a sub-pixel SP1 of the first color, a sub-pixel SP2 of the second color, and a sub-pixel SP3 of the third color. The first color, the second color, and the third color are different colors from each other. Note that the pixel PX may also include a sub-pixel SP of another color such as white on the basis of or instead of one of the sub-pixels SP1, SP2, and SP3.

[0041] 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 thin film transistors, for example.

[0042] The gate electrode of the pixel switch 2 is connected to the scan line GL. One of the source electrode and the drain electrode of the pixel switch 2 is connected to the signal line SL, and the other is connected to the gate electrode of the driving transistor 3 and the capacitor 4. In the driving transistor 3, one of the source electrode and the drain electrode is connected to the power supply line PL and the capacitor 4, and the other is connected to the anode of the display element DE.

[0043] It should be noted that the structure of the pixel circuit 1 is not limited to the illustrated example. For example, the pixel circuit 1 may also include more thin film transistors and capacitors.

[0044] The display element DE is an organic light emitting diode (OLED) as a light emitting element, and is sometimes referred to as an organic EL element.

[0045] Although not described in detail, terminals for connecting an IC chip or a flexible printed circuit board are provided in the peripheral region SA.

[0046] Figure 2 It is a schematic top view showing an example of the layout of the sub-pixels SP1, SP2, and SP3. The sub-pixels SP2 and the sub-pixel SP3 are arranged in the second direction Y. The sub-pixel SP1 and the sub-pixel SP2 are arranged in the first direction X, and the sub-pixel SP1 and the sub-pixel SP3 are arranged in the first direction X.

[0047] In the case where the sub-pixels SP1, SP2, and SP3 are in this layout, in one example, columns in which the sub-pixels SP2 and the sub-pixel SP3 are alternately arranged in the second direction Y, and columns in which a plurality of sub-pixels SP1 are repeatedly arranged in the second direction Y are formed in the display area DA. These columns are alternately arranged in the first direction X.

[0048] It should be noted that the layout of the sub-pixels SP1, SP2, and SP3 is not limited to Figure 2 the example. As another example, the sub-pixels SP1, SP2, and SP3 in each pixel PX may also be arranged in sequence in the first direction X.

[0049] An inorganic insulating layer 5 and a partition wall 6 are disposed in the display area DA. The inorganic insulating layer 5 has openings A51, A52, and A53 in the sub-pixels SP1, SP2, and SP3, respectively. The inorganic insulating layer 5 having these openings A51, A52, and A53 is sometimes referred to as a rib.

[0050] The partition wall 6 overlaps with the inorganic insulating layer 5 in a top view. The partition wall 6 is formed in a lattice shape surrounding the openings A51, A52, and A53. The partition wall 6 has openings A61, A62, and A63 surrounded by the edge portions of the upper part of the partition wall 6, which will be described later Figure 4 The opening A61 (the first opening) surrounds the opening A51 in the sub-pixel SP1. The opening A62 (the second opening) surrounds the opening A52 in the sub-pixel SP2. The opening A63 (the third opening) surrounds the opening A53 in the sub-pixel SP3. In Figure 2In the example, the corners of the openings A51, A52, A53 and the openings A61, A62, A63 are each formed into a rounded shape, but they may also be formed into a right angle. The openings A51, A52, A53 and the openings A61, A62, A63 may each also be formed into other shapes such as a circular shape or an elliptical shape. The partition wall 6 has conductivity and is electrically connected to the terminal of the common potential among the plurality of terminals provided in the peripheral region SA shown in Figure 1 the common potential terminal among the plurality of terminals provided in the peripheral region SA shown.

[0051] The sub-pixels SP1, SP2, SP3 each include display elements DE1, DE2, DE3 as display elements DE.

[0052] The display element DE1 (first light-emitting element) of the sub-pixel SP1 has a lower electrode LE1, an upper electrode UE1, and an organic layer OR1 that respectively overlap with the openings A51, A61. The display element DE1 having the lower electrode LE1, the organic layer OR1, and the upper electrode UE1 is surrounded by the opening A61 in a top view. The peripheral portions of the lower electrode LE1, the organic layer OR1, and the upper electrode UE1 overlap with the inorganic insulating layer 5 in a top view. The organic layer OR1 includes, for example, a light-emitting layer that emits light in the green wavelength range.

[0053] The display element DE2 (second light-emitting element) of the sub-pixel SP2 has a lower electrode LE2, an upper electrode UE2, and an organic layer OR2 that respectively overlap with the openings A52, A62. The display element DE2 having the lower electrode LE2, the organic layer OR2, and the upper electrode UE2 is surrounded by the opening A62 in a top view. The peripheral portions of the lower electrode LE2, the organic layer OR2, and the upper electrode UE2 overlap with the inorganic insulating layer 5 in a top view. The organic layer OR2 includes, for example, a light-emitting layer that emits light in the blue wavelength range.

[0054] The display element DE3 (third light-emitting element) of the sub-pixel SP3 has a lower electrode LE3, an upper electrode UE3, and an organic layer OR3 that respectively overlap with the openings A53, A63. The display element DE3 having the lower electrode LE3, the organic layer OR3, and the upper electrode UE3 is surrounded by the opening A63 in a top view. The peripheral portions of the lower electrode LE3, the organic layer OR3, and the upper electrode UE3 overlap with the inorganic insulating layer 5 in a top view. The organic layer OR3 includes, for example, a light-emitting layer that emits light in the red wavelength range.

[0055] In Figure 2 the example, the outer shapes of the lower electrodes LE1, LE2, LE3 are represented by dashed lines, and the outer shapes of the organic layers OR1, OR2, OR3 and the upper electrodes UE1, UE2, UE3 are represented by dotted lines. In addition, the outer shapes of the illustrated lower electrode, organic layer, and upper electrode do not necessarily reflect the accurate shapes.

[0056] The lower electrodes LE1, LE2, and LE3 correspond to, for example, the anodes of the display elements. The upper electrodes UE1, UE2, and UE3 correspond to the cathodes or common electrodes of the display elements and are in contact with the partition wall 6.

[0057] In Figure 2 's example, the area of the opening A51, the area of the opening A52, and the area of the opening A53 are different from each other. The area of the opening A51 is larger than the area of the opening A52, and the area of the opening A52 is larger than the area of the opening A53. In other words, the area of the lower electrode LE1 exposed from the opening A51 is larger than the area of the lower electrode LE2 exposed from the opening A52, and the area of the lower electrode LE2 exposed from the opening A52 is larger than the area of the lower electrode LE3 exposed from the opening A53. It should be noted that the size relationship of the areas of the openings A51, A52, and A53 is not limited to the example shown in the figure.

[0058] Similarly, in Figure 2 's example, the area of the opening A61, the area of the opening A62, and the area of the opening A63 are different from each other. The area of the opening A61 is larger than the area of the opening A62. The area of the opening A62 is larger than the area of the opening A63. It should be noted that the size relationship of the areas of the openings A61, A62, and A63 is not limited to the example shown in the figure.

[0059] Figure 3 is a top view showing an example of the layout of the openings A61, A62, A63 of the partition wall 6 and the lenses ML1, ML2. It should be noted that in Figure 3 the illustration of the lower electrodes, organic layers, upper electrodes, etc. of the display elements constituting each sub-pixel is omitted.

[0060] In the opening A61, the edge portion of the partition wall 6 includes an opening edge AE1 (first opening edge) and an opening edge AE2 (second opening edge). The opening A61 has a center line AC1 (first center line). The opening edges AE1, AE2, and the center line AC1 are parallel in the second direction Y. The opening edges AE1 and AE2 face each other in the first direction X. The center line AC1 is located at a position equidistant from the opening edges AE1 and AE2 along the first direction X. In Figure 3 's example, the distance D1 along the first direction X between the opening edge AE1 and the center line AC1 and the distance D2 along the first direction X between the opening edge AE2 and the center line AC1 are equal (D1 = D2).

[0061] In the opening A62, the edge portion of the partition wall 6 includes an opening edge AE3 (the third opening edge) and an opening edge AE4 (the fourth opening edge). The opening A62 has a center line AC2 (the second center line). The opening edges AE3, AE4, and the center line AC2 are parallel in the second direction Y. The opening edges AE3, AE4 face each other in the first direction X. The center line AC2 is located at a position equidistant from the opening edges AE3, AE4 along the first direction X. In Figure 3 this example, the distance D3 along the first direction X between the opening edge AE3 and the center line AC2 and the distance D4 along the first direction X between the opening edge AE4 and the center line AC2 are equal (D3 = D4).

[0062] In the opening A63, the edge portion of the partition wall 6 includes an opening edge AE5 (the fifth opening edge) and an opening edge AE6 (the sixth opening edge). The opening A63 has a center line AC3 (the third center line). The opening edges AE5, AE6, and the center line AC3 are parallel in the second direction Y. The opening edges AE5, AE6 face each other in the first direction X. The center line AC3 is located at a position equidistant from the opening edges AE5, AE6 along the first direction X. In Figure 3 this example, the distance D5 along the first direction X between the opening edge AE5 and the center line AC3 and the distance D6 along the first direction X between the opening edge AE6 and the center line AC3 are equal (D5 = D6).

[0063] The display device DSP further includes lenses ML1 (the first lens) and ML2 (the second lens). In Figure 3 this example, the lenses ML1, ML2 extend in the second direction Y and are opposed to a plurality of sub-pixels arranged in the second direction Y.

[0064] The lens ML1 coincides with a part of the opening A61. The lens ML1 has lens edges ME1, ME2, and a lens center line MC1 (the first lens center line). The lens edges ME1, ME2, and the lens center line MC1 are parallel in the second direction Y. In the illustrated example, the lens edge ME1 coincides with the partition wall 6 in a plan view and is located between the opening edge AE1 and the opening edge AE4 and between the opening edge AE1 and the opening edge AE6 in the first direction X. In addition, the lens edge ME2 intersects the partition wall 6 in a plan view and coincides with the opening A61 and is located between the opening edge AE2 and the center line AC1 in the first direction X. Moreover, the lens ML1 covers the opening edge AE1 but does not cover the opening edge AE2. The lens center line MC1 is located between the center line AC1 and the opening edge AE1 in a plan view.

[0065] In the illustrated example, the lens ML1 does not completely cover the opening A61 in the first direction X. However, it is not limited to this example. The lens ML1 may also completely cover the opening A61.

[0066] The lens ML2 is continuously coincident with a part of each of the openings A62 and A63. The lens ML2 has lens edges ME3, ME4, and a lens center line MC2 (the second lens center line). The lens edges ME3, ME4, and the lens center line MC2 are parallel in the second direction Y. In the illustrated example, the lens edge ME3 coincides with the partition 6 in a plan view, and is located between the opening edge AE2 and the opening edge AE3, and between the opening edge AE2 and the opening edge AE5 in the first direction X. Further, the lens edge ME4 intersects the partition 6 in a plan view, coincides with the openings A62 and A63, and is located between the opening edge AE4 and the center line AC2, and between the opening edge AE6 and the center line AC3 in the first direction X. Moreover, the lens ML2 continuously covers the opening edges AE3 and AE5, but does not cover the opening edges AE4 and AE6. The lens center line MC2 is located between the center line AC2 and the opening edge AE3, and between the center line AC3 and the opening edge AE5.

[0067] In the illustrated example, the lens ML2 does not completely cover the openings A62 and A63 in the first direction X. However, it is not limited to this example. The lens ML2 may also completely cover the openings A62 and A63.

[0068] In this specification, the lens center line is a line connecting a plurality of principal points of the lens. The principal point is a point where the principal plane of the lens is orthogonal to the optical axis. The principal plane is a plane that includes the intersection of the incident light ray before incidence and the emitted light ray when a light ray parallel to the optical axis is incident on the lens, and is orthogonal to the optical axis.

[0069] Figure 4 It is a cross-sectional view showing a configuration example of the display device DSP along the Figure 3 A - A' line in. The circuit layer 11 is disposed on the substrate 10. The circuit layer 11 includes Figure 1 various circuits such as the pixel circuit 1 shown, and various wirings such as the scanning line GL, the signal line SL, and the power supply line PL. The circuit layer 11 is covered by an insulating layer 12. The insulating layer 12 is an organic insulating layer that planarizes the unevenness generated by the circuit layer 11.

[0070] The lower electrodes LE1 and LE2 are disposed on the insulating layer 12 and are separated from each other. The inorganic insulating layer 5 is disposed on the insulating layer 12 and the lower electrodes LE1 and LE2. The opening A51 of the inorganic insulating layer 5 coincides with the lower electrode LE1, and the opening A52 coincides with the lower electrode LE2. The peripheral portions of the lower electrodes LE1 and LE2 are covered by the inorganic insulating layer 5. Between the lower electrodes LE1 and LE2 that are adjacent to each other, the insulating layer 12 is covered by the inorganic insulating layer 5. The lower electrodes LE1 and LE2 are connected to the pixel circuits 1 of the sub - pixels SP1 and SP2 respectively through contact holes provided in the insulating layer 12. It should be noted that inFigure 4 The contact holes of the insulating layer 12 are omitted.

[0071] The partition wall 6 includes a lower portion 61 having conductivity disposed on the inorganic insulating layer 5 and an upper portion 62 disposed on the lower portion 61. The lower portion 61 surrounds the display elements DE1 and DE2 respectively in a plan view. The upper portion 62 has edge portions AE that surround the openings A61 and A62 respectively in a plan view. The edge portions AE protrude more than the side surfaces of the lower portion 61. Such a shape of the partition wall 6 can also be referred to as a hanging shape.

[0072] In the illustrated example, the lower portion 61 has a first conductive layer 63 on the inorganic insulating layer 5 and a second conductive layer 64 disposed on the first conductive layer 63. For example, the first conductive layer 63 is formed thinner than the second conductive layer 64. In addition, in the illustrated example, both end portions of the first conductive layer 63 protrude from the side surfaces of the second conductive layer 64.

[0073] The upper portion 62 has a thin film 65 disposed on the second conductive layer 64 and a thin film 66 disposed on the thin film 65. Both end portions of the thin film 65 and the thin film 66 protrude from the side surfaces of the second conductive layer 64. In the illustrated example, the end portions of the thin film 65 surround the openings A61 and A62. The edge portion AE corresponds to the end portions of the thin film 65, for example.

[0074] The organic layer OR1 passes through the opening A51 to contact the lower electrode LE1, covers the lower electrode LE1 exposed from the opening A51, and its peripheral portion is located on the inorganic insulating layer 5. The upper electrode UE1 covers the organic layer OR1 and contacts the lower portion 61.

[0075] The organic layer OR2 passes through the opening A52 to contact the lower electrode LE2, covers the lower electrode LE2 exposed from the opening A52, and its peripheral portion is located on the inorganic insulating layer 5. The upper electrode UE2 covers the organic layer OR2 and contacts the lower portion 61.

[0076] In Figure 4 the example, the sub-pixel SP1 has a cover layer CP1 and a first sealing layer SE11, and the sub-pixel SP2 has a cover layer CP2 and a first sealing layer SE12. The cover layers CP1 and CP2 each function as an optical adjustment layer that improves the light acquisition efficiency of the light emitted from the organic layers OR1 and OR2. It should be noted that the cover layers CP1 and CP2 can also be omitted. The cover layer CP1 is disposed on the upper electrode UE1. The cover layer CP2 is disposed on the upper electrode UE2.

[0077] The first sealing layer SE11 is disposed on the cover layer CP1, contacts the partition wall 6, and continuously covers each component of the sub-pixel SP1. The first sealing layer SE12 is disposed on the cover layer CP2, contacts the partition wall 6, and continuously covers each component of the sub-pixel SP2.

[0078] In Figure 4 the example, a part of each of the organic layer OR1, the upper electrode UE1, and the cover layer CP1 is located on the partition wall 6 around the sub-pixel SP1. These parts are separated from the parts of the organic layer OR1, the upper electrode UE1, and the cover layer CP1 that are located in the opening A51 (the parts constituting the display element DE1).

[0079] Similarly, a part of each of the organic layer OR2, the upper electrode UE2, and the cover layer CP2 is located on the partition wall 6 around the sub-pixel SP2, and these parts are separated from the parts of the organic layer OR2, the upper electrode UE2, and the cover layer CP2 that are located in the opening A52 (the parts constituting the display element DE2).

[0080] In the following description, the multilayer body including the organic layer OR1, the upper electrode UE1, and the cover layer CP1 is referred to as the stacked film FL1, and the multilayer body including the organic layer OR2, the upper electrode UE2, and the cover layer CP2 is referred to as the stacked film FL2.

[0081] The ends of the first sealing layers SE11 and SE12, and the ends of the stacked films FL1 and FL2 are respectively located on the partition wall 6. In Figure 4 the example, the stacked film FL1 and the first sealing layer SE11 on the partition wall 6 between the sub-pixels SP1 and SP2 are separated from the stacked film FL2 and the first sealing layer SE12 on the partition wall 6.

[0082] The partition wall 6, and the first sealing layers SE11 and SE12 are covered by the organic insulating layer RS1 (the first organic insulating layer). The organic insulating layer RS1 is covered by the second sealing layer SE2. The second sealing layer SE2 is covered by the organic insulating layer RS2 (the second organic insulating layer). In the illustrated example, the organic insulating layer RS2 is thicker than the organic insulating layer RS1.

[0083] The lenses ML1 and ML2 are arranged on the organic insulating layer RS2. The lenses ML1 and ML2 are formed in a convex shape that protrudes in the third direction Z to the side opposite to the openings A61 and A62. The lens ML1 coincides with the lower electrode LE1, the stacked film FL1, and the first sealing layer SE11 in the third direction Z, and the lens ML2 coincides with the lower electrode LE2, the stacked film FL2, and the first sealing layer SE12 in the third direction Z. In one example, the lenses ML1 and ML2 are covered by an air layer. In another example, they are covered by a material having a refractive index smaller than the refractive indices of the lenses ML1 and ML2.

[0084] It should be noted that the positions of the respective foci of the lenses ML1 and ML2 are preferably the same as the positions of the light-emitting layers included in the organic layers OR1 and OR2. It should be noted that, for example, by changing the thicknesses of the organic insulating layers RS1 and RS2, the positions of the foci of the lenses ML1 and ML2 can be made the same as the positions of the light-emitting layers.

[0085] A cover member such as a polarizing plate or a cover glass may be further disposed above the lenses ML1 and ML2.

[0086] The display device DSP further includes a light-shielding layer BM disposed above the organic insulating layer RS2. The light-shielding layer BM covers the space between the lenses ML1 and ML2. In the illustrated example, both ends of the light-shielding layer BM are covered by the lenses ML1 and ML2. It should be noted that the light-shielding layer BM only needs to cover at least the portion in the opening of the partition 6 that is not covered by the lens.

[0087] The inorganic insulating layer 5, the first sealing layers SE11 and SE12, and the second sealing layer SE2 are formed of an inorganic insulating material such as silicon nitride (SiNx), silicon oxide (SiOx), silicon oxynitride (SiON), or aluminum oxide (Al2O3). The organic insulating layers RS1 and RS2 are formed of a resin material (organic insulating material) such as an epoxy resin or an acrylic resin.

[0088] The lower portion 61 of the partition 6 is formed of a conductive material and is electrically connected to the upper electrodes UE1 and UE2. The first conductive layer 63 is formed of a titanium-based material such as titanium or a titanium compound. The second conductive layer 64 is formed of a material different from the first conductive layer 63 and the upper portion 62, and is formed of an aluminum-based material such as aluminum or an aluminum compound, for example.

[0089] The upper portion 62 of the partition 6 is formed of a conductive material, for example, but may also be formed of an insulating material. The thin film 65 is formed of a titanium-based material such as titanium or a titanium compound. The thin film 66 is formed of an oxide conductive material such as indium tin oxide (ITO).

[0090] The lower electrodes LE1 and LE2 are a multilayer body including a transparent layer formed of an oxide conductive material such as indium tin oxide (ITO) and a reflective layer formed of a metal material such as silver. In one example, the lower electrodes LE1 and LE2 are a multilayer body including a reflective layer between a pair of transparent layers. The lower transparent layer functions as a close contact layer in close contact with the insulating layer 12.

[0091] In one example, the organic layer OR1 includes a light-emitting layer formed of a material that emits light in the green wavelength range, and the organic layer OR2 includes a light-emitting layer formed of a material that emits light in the blue wavelength range. In another example, the organic layer OR1 may also include a light-emitting layer formed of a material that emits light in the blue wavelength range, and the organic layer OR2 may also include a light-emitting layer formed of a material that emits light in the green wavelength range. Additionally, the organic layers OR1 and OR2 each include a plurality of 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.

[0092] The upper electrodes UE1 and UE2 are formed of a metal material such as an alloy of magnesium and silver (MgAg), for example. The cover layers CP1 and CP2 are multi-layers of a plurality of thin films. The plurality of thin films are all transparent and have different refractive indices from each other.

[0093] The lenses ML1 and ML2 are formed of a transparent resin material such as epoxy resin, acrylic resin, or polyimide resin, for example.

[0094] Next, use Figure 5 to explain the effects of this embodiment. Figure 5 is a diagram for explaining the effects of this embodiment. It should be noted that hereinafter, the direction from the center line AC1 toward the lens center line MC1 along the first direction X will be defined as the direction X1, and the direction from the lens center line MC1 toward the center line AC1 along the first direction X will be defined as the direction X2.

[0095] The light ray L1 emitted from the display element DE1 along the third direction Z and passing through the lens center line MC1 travels almost without refraction in the lens ML1. In the illustrated example, the light ray L1 travels along the third direction Z.

[0096] In addition, the light ray L2 emitted from the display element DE1 along the third direction Z and incident near the lens edge ME2 of the lens ML1 is refracted at the interface between the lens ML1 and air. The refracted light ray L2 travels along a direction inclined at an angle θ1 from the third direction Z toward the direction X1.

[0097] Moreover, the light ray L3 emitted from the display element DE1 near the opening edge AE1 along the third direction Z and incident on the lens ML1 is refracted at the interface between the lens ML1 and air. The refracted light ray L3 travels along a direction inclined at an angle θ2 from the third direction Z toward the direction X2.

[0098] In the illustrated example, the region that combines the region between the light rays L1 and L2 and the region between the light rays L1 and L3 is defined as the region AR1, and the region other than this is defined as AR2. At this time, a user located within the region AR1 can visually confirm the image displayed on the display device DSP. On the other hand, a user located within the region AR2 can hardly recognize the image.

[0099] Here, when the lens center line MC1 coincides with the center line AC1, the angle θ1 becomes equal to the angle θ2 (θ1 = θ2). On the other hand, as in the present embodiment, if the lens center line MC1 approaches the opening edge AE1, the angle θ2 becomes smaller, and the angle θ2 is smaller than the angle θ1 (θ1 > θ2). Therefore, the region on the X2 side of the region AR1 that is farther from the lens center line MC1 is narrower than the region on the X1 side of the region AR1 that is closer to the lens center line MC1. Therefore, the viewing angle on the X2 side can be restricted.

[0100] Next, the case where the display device DSP of the present embodiment is mounted on a vehicle such as an automobile will be described. Figure 6 FIG. is a view showing the display device DSP of the present embodiment mounted on a vehicle-mounted device. As an example, the case where the display device DSP is mounted between the driver's seat and the front passenger seat will be described. It should be noted that the display device DSP can also be mounted in front of the front passenger seat.

[0101] For example, during driving, it is required that the image displayed on the display device DSP is not easily visually confirmed from the driver's seat side. On the other hand, the image can be visually confirmed from the front passenger seat side. In this case, the display device DSP is arranged at a position where the passenger PAS in the front passenger seat is included in the region AR1 and the driver DRV is included in the region AR2. Then, the passenger PAS in the front passenger seat located within the region AR1 can visually confirm the screen 101 on which the image is displayed in the display area DA. On the other hand, the visual confirmation of the displayed image from the driver DRV located within the region AR2 can be restricted so that the driver DRV visually confirms an image that is darker than the front passenger seat side or a screen 102 on which no image is displayed. In this way, by restricting the viewing angle on the driver's seat side, the visual confirmation of the image from the driver DRV can be restricted.

[0102] Figure 7 FIG. is a cross-sectional view showing another configuration example of the display device DSP along the Figure 3 A-A' line in. In Figure 7 the example shown, the ends of the light-shielding layer BM are respectively in contact with the lens edges ME1 to ME4.

[0103] In Figure 7 the display device DSP shown, it is also possible to obtain the same as Figure 4The shown display device DSP has the same effect.

[0104] Figure 8 It is a cross-sectional view showing another configuration example of the display device DSP along the A-A' line in Figure 3 . Figure 8 The difference between the shown display device DSP and Figure 4 the shown display device DSP is that it does not have Figure 4 the shown light-shielding layer BM, and the lens ML1 and the lens ML2 are in contact with each other.

[0105] The lens ML1 and the lens ML2 are in contact with each other. Specifically, the lens edge ME1 of the lens ML1 is in contact with the lens edge ME4 of the lens ML2, and the lens edge ME2 of the lens ML1 is in contact with the lens edge ME3 of the lens ML2. That is, the opening of the partition wall 6 is completely covered by the lens. It should be noted that in the example of Figure 8 , the lens edge ME1 and the lens edge ME4, and the lens edge ME2 and the lens edge ME3 are in contact with each other on the upper surface of the organic insulating layer RS2, but they can also be in contact with each other above the organic insulating layer RS2.

[0106] In Figure 8 the shown display device DSP, the opening of the partition wall 6 is completely covered by the lens. Therefore, there is no need to provide Figure 4 the shown light-shielding layer BM. Thus, the brightness of the display device DSP can be improved.

[0107] Figure 9 It is a cross-sectional view showing another configuration example of the display device DSP along the A-A' line in Figure 3 . Figure 9 The difference between the shown display device DSP and Figure 4 the shown display device DSP is that the cross-sectional shapes of the lenses ML1 and ML2 are different.

[0108] The lens ML1 has a flat surface P1 at the top. The lens ML2 has a flat surface P2 at the top. In the example of Figure 9 , the surfaces P1 and P2 are surfaces parallel to the first direction X and the second direction Y. It should be noted that the surfaces P1 and P2 can also be inclined with respect to the surfaces formed by the first direction X and the second direction Y.

[0109] In Figure 9 the shown display device DSP, the same effect as that of Figure 4 the shown display device DSP can also be obtained.

[0110] Figure 10 It is a cross-sectional view showing another configuration example of the display device DSP along the A-A' line in Figure 3 . Figure 10The shown display device DSP and Figure 4 The difference between the shown display device DSP is that the cross-sectional shapes of the lenses ML1 and ML2 are different.

[0111] The lens ML1 has an asymmetric cross-section with respect to the lens center line MC1. In Figure 10 the example, the lens edge ME1 is formed in a planar shape parallel to the second direction Y and the third direction Z. Similarly to the lens ML1 in the lens ML2, the lens edge ME3 is formed in a planar shape parallel to the second direction Y and the third direction Z.

[0112] In Figure 10 the shown display device DSP, the same effects as those of Figure 4 the shown display device DSP can also be obtained.

[0113] Figure 11 is a cross-sectional view showing another configuration example of the display device DSP along the A-A' line in Figure 3 . Figure 11 The difference between the shown display device DSP and Figure 4 the shown display device DSP is that it has a color filter.

[0114] The display device DSP further includes color filters CF1 and CF2. The color filter CF1 is disposed between the organic insulating layer RS2 and the lens ML1 in the third direction Z. The color filter CF1 is disposed directly above the display element DE1. As an example, the color filter CF1 is formed of a resin material colored green.

[0115] The color filter CF2 is disposed between the organic insulating layer RS2 and the lens ML2 in the third direction Z. The color filter CF2 is disposed directly above the display element DE2. As an example, the color filter CF2 is formed of a resin material colored blue.

[0116] The light-shielding layer BM overlaps with the peripheral portions of the color filters CF1 and CF2. In the illustrated example, the light-shielding layer BM covers the lens edges ME1 to ME4 in a plan view.

[0117] It should be noted that although not shown, the display device DSP has a color filter disposed directly above Figure 2 the shown display element DE3. As an example, the color filter is formed of a resin material colored red.

[0118] In Figure 11In the illustrated display device DSP, for example, green light emitted from the display element DE1 passes through the color filter CF1. On the other hand, blue light emitted from the display element DE2 is absorbed by the color filter CF1. Thereby, color mixing of light can be suppressed, and a reduction in display quality can be suppressed.

[0119] In Figure 11 the illustrated display device DSP, the same effect as that of Figure 4 the illustrated display device DSP can also be obtained.

[0120] Figure 12 is a schematic top view showing an example of the layout of the lenses ML1 and ML2. The display device DSP further includes a plurality of pixels PX1 (first pixels) in the display area DA. The plurality of pixels PX1 each include openings A61, A62, and A63. In the illustrated example, the plurality of pixels PX1 are repeatedly arranged in the second direction Y. In addition, columns of the plurality of pixels PX1 arranged in the second direction Y are repeatedly arranged in the first direction X.

[0121] The lenses ML1 and ML2 are continuously coincident with the plurality of pixels PX1 arranged along the second direction Y in the third direction Z. Specifically, the lens ML1 is continuously coincident with the plurality of openings A61 arranged along the second direction Y in the third direction Z. In addition, the lens ML2 is continuously coincident with the openings A62 and A63 alternately arranged along the second direction Y in the third direction Z. It should be noted that the lenses ML1 and ML2 may also be interrupted for each pixel in the second direction Y.

[0122] In Figure 12 the illustrated display device DSP, the same effect as that of Figure 4 the illustrated display device DSP can also be obtained.

[0123] Figure 13 is a schematic top view showing another example of the layout of the lenses ML1 and ML2. The display device DSP further includes a plurality of pixels PX2 (second pixels) in the display area DA. Each of the plurality of pixels PX2 includes openings A64, A65, and A66 surrounded by the edge portion AE of the upper portion 62 of the partition wall 6 shown by Figure 4 Each of the openings A64, A65, and A66 coincides with a plurality of display elements included in the pixel PX2 (not shown). The pixel PX2 is configured in the same manner as the above-described pixel PX1, and although detailed description is omitted, it has the same display elements as the display elements DE1, DE2, and DE3 included in the pixel PX1.

[0124] In Figure 13In the illustrated example, the opening A64 (the fourth opening) is adjacent to each of the openings A62, A63, A65, and A66 in the first direction X. Further, the opening A65 (the fifth opening) is adjacent to the openings A61 and A64 in the first direction X and is adjacent to the opening A66 in the second direction Y. Moreover, the opening A66 (the sixth opening) is adjacent to the openings A61 and A64 in the first direction X and is adjacent to the opening A65 in the second direction Y.

[0125] None of the openings A64, A65, and A66 coincides with any lens, nor does it coincide with the lenses ML1 and ML2 that coincide with the pixel PX1 in the third direction Z. Therefore, the light emitted from the display element that coincides with each of the openings A64, A65, and A66 is not affected by the viewing angle limitation of the lens.

[0126] A plurality of pixels PX1 are repeatedly arranged in the second direction Y. A plurality of pixels PX2 are repeatedly arranged in the second direction Y. The columns of the plurality of pixels PX1 arranged in the second direction Y and the columns of the plurality of pixels PX2 arranged in the second direction Y are alternately arranged in the first direction X. In one example, the number of pixels PX1 arranged in the display area DA is almost the same as the number of pixels PX2.

[0127] Here, regarding the pixels PX1 and PX2 alternately arranged in the first direction X, the relationship between the length W1 of the pixel PX1 and the pixel PX2 adjacent in the first direction X along the first direction X and the length H1 of one pixel of the pixels PX1 arranged in the second direction Y along the second direction Y is as follows. In the illustrated example, the lengths of the pixels PX1 and PX2 along the first direction X are equal to each other. Further, the length of the pixel PX1 along the first direction X is equal to the length along the second direction Y. That is, the length W1 becomes about twice the length H1 (W1 = 2 × H1).

[0128] As described above, in the pixel PX1, the lens ML1 coincides with the opening A61, and the lenses ML2 coincide with the openings A62 and A63. Further, in the pixel PX2, the lenses ML1 and ML2 do not coincide with each of the openings A64, A65, and A66. That is, the lenses ML1 and ML2 are arranged with one pixel interval in the first direction X. Note that when n is an integer of 2 or more, the lenses may be arranged with an interval of n pixels. In this case, the length W1 becomes about n times the length H1 (W1 = n × H1).

[0129] In Figure 13In the illustrated display device DSP, when multiple pixels PX1 are lit and multiple pixels PX2 are not lit (hereinafter referred to as the first mode), the viewing angle of the display device DSP is restricted. On the other hand, when multiple pixels PX1 are not lit and multiple pixels PX2 are lit, or when both multiple pixels PX1 and PX2 are lit (hereinafter referred to as the second mode), the viewing angle of the display device DSP is expanded compared to the case of the first mode. Therefore, by switching between the first mode and the second mode according to the use of the display device DSP, the viewing angle of the display device DSP can be controlled.

[0130] It should be noted that Figure 13 the number of pixels PX1 in the illustrated display device DSP becomes Figure 12 about half of the number of pixels PX1 in the illustrated display device DSP. Therefore, Figure 13 the resolution of the image displayed by the display device DSP in the first mode becomes Figure 12 about half of the resolution of the image displayed by the display device DSP. It should be noted that the resolution here is defined as the number of pixels used for display per unit area. In addition, in Figure 13 the illustrated display device DSP, the number of pixels PX2 is almost the same as the number of pixels PX1. Therefore, when pixels PX1 are not lit and pixels PX2 are lit, Figure 13 the resolution of the image displayed by the display device DSP becomes Figure 12 about half of the resolution of the image displayed by the display device DSP. That is to say, the resolution of the image in the above situation is almost equal to the resolution of the image displayed in the first mode.

[0131] On the other hand, when both pixels PX1 and PX2 are lit, the light of both pixels PX1 and PX2 can be visually confirmed from the X1 direction side, and only the light of pixel PX2 can be visually confirmed from the X2 direction side. Therefore, when both pixels PX1 and PX2 are lit, when observing the image displayed by the display device DSP from the X1 direction side Figure 13 the resolution of the image in this case is almost equal to Figure 12 the resolution of the image displayed by the display device DSP. That is to say, the resolution of the image in the above situation becomes about twice the resolution of the image displayed in the first mode. In addition, when both pixels PX1 and PX2 are lit, when observing the image displayed by the display device DSP from the X2 direction side Figure 13 the resolution of the image in this case becomes Figure 12 about half of the resolution of the image displayed by the display device DSP. That is to say, the resolution of the image in the above situation is almost equal to the resolution of the image displayed in the first mode.

[0132] Next, an example will be described where Figure 13 the illustrated display device DSP is mounted on a vehicle such as an automobile. Figure 14 FIG. is a diagram showing the display device DSP of the present embodiment mounted on an in-vehicle device. As an example, a case where the display device DSP is mounted between the driver's seat and the front passenger seat will be described. Note that the display device DSP may also be mounted in front of the front passenger seat.

[0133] When an image is displayed in the first mode, Figure 6 similarly to the case described above, the passenger PAS in the front passenger seat located within the region AR1 can visually confirm the screen 101 on which the image is displayed in the display region DA. On the other hand, the driver DRV located within the region AR2 can be restricted from visually confirming the displayed image, and can visually confirm the screen 102 on which the image is displayed darker than the front passenger seat side or on which no image is displayed.

[0134] When an image is displayed in the second mode, the passenger PAS in the front passenger seat can visually confirm the screen 101 on which the image is displayed in the display region DA. On the other hand, the driver DRV can visually confirm the screen 103 on which the same image as the image visually confirmed by the passenger PAS in the front passenger seat is displayed.

[0135] During driving, when it is desired that the image displayed on the display device DSP is not easily visually confirmed from the driver's seat side and the image can be visually confirmed from the front passenger seat side, the image is displayed in the first mode. As a result, the visual confirmation of the image from the driver's seat side is restricted, and the image can be visually confirmed well from the front passenger seat side. On the other hand, when it is desired that the image can be visually confirmed from both the driver's seat side and the front passenger seat side in a state where the engine is turned off, the image is displayed in the second mode. As a result, the image can be visually confirmed well from both the driver's seat side and the front passenger seat side. In this way, by switching between the first mode and the second mode, the viewing angle is controlled, and in particular, the visual confirmation of the image from the driver's seat side can be switched.

[0136] Figure 15 FIG. is a diagram showing an example of a pixel applicable to Figure 13 the display device DSP shown in Figure 13 The display device DSP includes pixels PX3 instead of the pixels PX1 and PX2 shown in FIG. A plurality of pixels PX3 are arranged over the entire surface of the display region DA and are arranged in a matrix in the first direction X and the second direction Y.

[0137] Pixel PX3 includes openings A61 to A66. Each of the openings A61 to A66 overlaps with a plurality of display elements (not shown) respectively. In one example, signal lines are individually electrically connected to the plurality of display elements, and individual image signals are supplied to the respective display elements.

[0138] The relationship between the length W2 along the first direction X of one pixel among the pixels PX3 arranged in the first direction X and the length H2 along the second direction Y of one pixel among the pixels PX3 arranged in the second direction Y is as follows. In the illustrated example, the length of the pixel PX3 along the first direction X is equal to the length along the second direction Y. That is, the length W2 is equal to the length H2 (W2 = H2).

[0139] As described above, Figure 13 the shown display device DSP has different resolutions for the images displayed using each mode. On the other hand, in Figure 15 the shown display device DSP, the length W2 along the first direction X of one pixel among the pixels PX3 arranged in the first direction X is equal to the length H2 along the second direction Y of one pixel among the pixels PX3 arranged in the second direction Y. Therefore, the difference in resolution between each mode becomes smaller, and the display quality can be improved.

[0140] Figure 16 is a schematic top view showing another example of the layout of the lenses ML1 and ML2. In Figure 16 the shown example, the opening A64 is adjacent to each of the openings A65 and A66 in the first direction X, and is adjacent to the opening A61 in the second direction Y. In addition, the opening A65 is adjacent to the opening A64 in the first direction X, and is adjacent to each of the openings A63 and A66 in the second direction Y. Moreover, the opening A66 is adjacent to the opening A64 in the first direction X, and is adjacent to each of the openings A62 and A65 in the second direction Y.

[0141] A plurality of pixels PX1 are repeatedly arranged in the first direction X. A plurality of pixels PX2 are repeatedly arranged in the first direction X. The columns of the plurality of pixels PX1 arranged in the first direction X and the columns of the plurality of pixels PX2 arranged in the first direction X are alternately arranged in the second direction Y. In one example, the number of pixels PX1 arranged in the display area DA is almost equal to the number of pixels PX2.

[0142] Here, the relationship between the length W3 along the first direction X of one pixel among the pixels PX1 arranged in the first direction X and the length H3 along the second direction Y of the pixel PX1 and the pixel PX2 that are adjacent in the second direction Y among the pixels PX1 and PX2 arranged alternately in the first direction X is as follows. In the illustrated example, the lengths along the second direction Y of the pixels PX1 and PX2 are equal to each other, and further, the length along the first direction X of the pixel PX1 is equal to the length along the second direction Y. That is, the length H3 becomes approximately twice the length W3 (H3 = 2 × W3).

[0143] The lenses ML1 and ML2 are arranged with one pixel interval in the second direction Y. It should be noted that when m is an integer of 2 or more, the lenses may be arranged with an interval of m pixels. In this case, the length H3 becomes approximately m times the length W3 (H3 = m × W3).

[0144] In Figure 16 the illustrated display device DSP, the same effect as Figure 13 the illustrated display device DSP can also be obtained.

[0145] Figure 17 is a diagram showing an example of pixels applicable to Figure 16 the illustrated display device DSP. The display device DSP includes pixels PX4 instead of Figure 16 the illustrated pixels PX1 and PX2. A plurality of pixels PX4 are arranged over the entire surface of the display area DA and are arranged in a matrix in the first direction X and the second direction Y.

[0146] The pixel PX4 includes openings A61 to A66. Each of the openings A61 to A66 overlaps with a plurality of display elements (not shown). In one example, signal lines are individually electrically connected to the plurality of display elements, and individual image signals are supplied to the respective display elements.

[0147] The relationship between the length W4 along the first direction X of one pixel among the pixels PX4 arranged in the first direction X and the length H4 along the second direction Y of one pixel among the pixels PX4 arranged in the second direction Y is as follows. In the illustrated example, the length along the first direction X of the pixel PX4 is equal to the length along the second direction Y. That is, the length W4 is equal to the length H4 (W4 = H4).

[0148] In Figure 17 the illustrated display device DSP, the same effect as Figure 15 the illustrated display device DSP can also be obtained.

[0149] Figure 18It is a schematic top view showing another example of the layout of lenses ML1 and ML2. A plurality of pixels PX1 and a plurality of pixels PX2 are alternately arranged in the first direction X and the second direction Y. That is, the length in the first direction X of the pixels PX1 and PX2 adjacent in the first direction X among the pixels PX1 and PX2 alternately arranged in the first direction X is equal to the length in the second direction Y of the pixels PX1 and PX2 adjacent in the second direction Y among the pixels PX1 and PX2 alternately arranged in the second direction Y. Therefore, similar to the Figure 15 and Figure 17 display device DSP shown, the difference in resolution between each mode can be reduced.

[0150] In Figure 18 the display device DSP shown, the same effect as that of the Figure 13 display device DSP shown can also be obtained.

[0151] Figure 19 It is a schematic top view showing another example of the layout of lenses ML1 and ML2. Figure 19 The arrangement of the openings A61 to A66 and the lenses ML1 and ML2 shown is such that it is the arrangement after inverting the arrangement of the Figure 18 openings A61 to A66 and the lenses ML1 and ML2 shown about the second direction Y as an axis.

[0152] In Figure 19 the display device DSP shown, the same effect as that of the Figure 13 display device DSP shown can also be obtained.

[0153] Figure 20 It is a schematic top view showing another example of the layout of lenses ML1 and ML2.

[0154] In Figure 20 the example shown, the opening A61 is adjacent to each of the openings A62, A63, A65, and A66 in the first direction X, and is adjacent to the opening A64 in the second direction Y. In addition, the opening A62 is adjacent to each of the openings A61 and A64 in the first direction X, and is adjacent to each of the openings A63 and A66 in the second direction Y. Moreover, the opening A63 is adjacent to each of the openings A61 and A64 in the first direction X, and is adjacent to each of the openings A62 and A65 in the second direction Y.

[0155] In Figure 20In the illustrated example, the opening A64 is adjacent to each of the openings A62, A63, A65, and A66 in the first direction X, and is adjacent to the opening A61 in the second direction Y. Further, the opening A65 is adjacent to each of the openings A61 and A64 in the first direction X, and is adjacent to each of the openings A63 and A66 in the second direction Y. Moreover, the opening A66 is adjacent to each of the openings A61 and A64 in the first direction X, and is adjacent to each of the openings A62 and A65 in the second direction Y.

[0156] A plurality of pixels PX1 having openings A61, A62, and A63 arranged as described above, and a plurality of pixels PX2 having openings A64, A65, and A66 arranged as described above are alternately arranged in the first direction X and the second direction Y.

[0157] In Figure 20 the illustrated display device DSP, the same effect as that of Figure 18 the illustrated display device DSP can also be obtained.

[0158] Figure 21 is a schematic top view showing another example of the layout of the lenses ML1 and ML2. Figure 21 The arrangement of the illustrated openings A61 to A66 and the lenses ML1 and ML2 is such that Figure 20 the arrangement of the illustrated openings A61 to A66 and the lenses ML1 and ML2 is reversed with the second direction Y as the axis.

[0159] In Figure 21 the illustrated display device DSP, the same effect as that of Figure 13 the illustrated display device DSP can also be obtained.

[0160] Figure 22 is a top view showing an example of the layout of the openings A61, A62, and A63 of the partition wall 6 and the lenses ML1, ML2, and ML3. The display device DSP further includes a lens ML3 (third lens).

[0161] In the illustrated example, the lens ML1 is formed in a top view to have a shape composed of lens edges ME1 and ME2 parallel to the second direction Y, and two semi-circular arcs protruding outward from the lens ML1 in the second direction Y. Further, the lens ML2 is formed in a top view to have a shape composed of lens edges ME3 and ME4 parallel to the second direction Y, and two semi-circular arcs protruding outward from the lens ML2 in the second direction Y. It should be noted that the lenses ML1 and ML2 may also be formed in an elliptical shape or a circular shape in a top view.

[0162] In the illustrated example, the lens ML3 is formed in a circular shape when viewed from above. It should be noted that the lens ML3 may also be formed in a shape composed of a straight line parallel to the first direction X and two arcs protruding outward from the lens ML3 in the first direction X or an elliptical shape when viewed from above.

[0163] The lens ML1 is formed in a convex shape protruding in the third direction Z on the side opposite to the opening A61. The lens ML2 is formed in a convex shape protruding in the third direction Z on the side opposite to the opening A62. The lens ML3 is formed in a convex shape protruding in the third direction Z on the side opposite to the opening A63.

[0164] The lens ML3 overlaps with a part of the opening A63. The lens ML3 has lens edges ME5, ME6, and a lens center line MC3 (the third lens center line). The lens edges ME5, ME6 are the intersections between the straight line passing through the center of the circular lens ML3 and parallel to the first direction X and the circumference of the lens ML3. It should be noted that when the shape of the lens ML3 viewed from above is not circular, the lens edges ME5, ME6 may also be straight lines parallel to the second direction Y. In the illustrated example, the lens edge ME5 coincides with the partition 6 when viewed from above and is located between the opening edge AE2 and the opening edge AE5 in the first direction X. In addition, the lens edge ME6 coincides with the opening A63 when viewed from above and is located between the opening edge AE6 and the center line AC3 in the first direction X.
