Description

[0001] This application claims priority and benefit to Korean Patent Application No. 10-2020-0022890, filed on February 25, 2020, with the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to a display device. Background Technology

[0003] Display devices, which serve as displays for images, include liquid crystal displays (LCDs), organic light-emitting diode (OLED) displays, and the like. These display devices are used in various electronic devices such as mobile phones, navigation devices, digital cameras, e-book readers, portable game consoles, and various other terminals.

[0004] Display devices are formed from multiple layers. For example, a display device can be formed from a multi-layered structure in which light-emitting elements, touch sensors, etc., are stacked on a substrate. An image can be displayed by allowing light emitted from the light-emitting elements to pass through these layers and reach the outside of the display device. However, some light generated from the light-emitting elements may be blocked, such as by reflection from the interlayer interfaces, and not reach the outside. Therefore, there are problems with the luminous efficiency and display degradation of the display device.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the background of the described technology, and therefore may contain information that does not constitute prior art known to a person skilled in the art in this country.

[0007] In addition, an exemplary embodiment provides a display device that can prevent a decrease in luminous efficiency even if errors occur in the manufacturing process of the display device (such as linewidth errors occurring in some layers of a multilayer structure and therefore the patterned size of the layers differs from the intended design size, or mask misalignment occurring during the formation of some layers and therefore the stacking position between the multilayers differs from the design, etc.).

[0052] The invention will be described more fully below with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention.

[0053] The accompanying drawings and descriptions should be considered illustrative rather than restrictive in nature. Throughout the specification, the same reference numerals denote the same elements.

[0054] Furthermore, in the accompanying drawings, the dimensions and thicknesses of each element are arbitrarily shown for better understanding and ease of description, but the invention is not limited thereto. In the accompanying drawings, the thicknesses of layers, films, panels, regions, etc., are exaggerated for clarity. In the accompanying drawings, the thicknesses of some layers and regions are exaggerated for better understanding and ease of description.

[0055] It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" another element, the element may be directly on said other element, or there may be intermediate elements present. Conversely, when an element is referred to as being "directly on" another element, there are no intermediate elements present. The terms "on" or "above" indicate that the element is positioned on or below a portion of an object, and do not necessarily indicate that it is positioned on the upper side of the object based on the direction of gravity.

[0056] Furthermore, unless explicitly stated otherwise, the word “contains” and its variations shall be understood to mean that the stated element is included, but not that any other element is excluded.

[0057] Furthermore, in this specification, the phrase "in a plane" refers to the target portion viewed from the top, and the phrase "in a cross section" refers to the cross section formed by vertically cutting the target portion viewed from the side.

[0058] First, refer to Figure 1 The present invention will describe a display device according to an exemplary embodiment.

[0059] Figure 1 This is a schematic top plan view of a display device according to an exemplary embodiment.

[0060] like Figure 1 As shown, the display device 1000 according to an exemplary embodiment includes a substrate 110, a partition wall 190 and a low-refractive-index layer 450 stacked with the substrate 110. The partition wall 190 may include a first opening 195, and the low-refractive-index layer 450 may include a second opening 455.

[0061] Multiple pixels PX are located on the substrate 110, and the first opening 195 and the second opening 455 can be located at each of the multiple pixels PX. The multiple pixels PX may include a red pixel R, a green pixel G, and a blue pixel B.

[0062] A red pixel R can display red, a green pixel G can display green, and a blue pixel B can display blue. However, this is just an example, and multiple pixels PX can be formed by pixels that display colors other than red, green, and blue. For example, multiple pixels PX can include pixels that display cyan, pixels that display magenta, and pixels that display yellow.

[0063] The planar shape of each of the first opening 195 and the second opening 455 can approximate a polygon comprising multiple sides. For example, the first opening 195 and the second opening 455 can each be formed as a quadrilateral in the plane. The first opening 195 and the second opening 455 can each be formed as a quadrilateral comprising two sides parallel to a first direction D1 and two sides parallel to a second direction D2. The second direction D2 can be a direction perpendicular to the first direction D1. Therefore, the first opening 195 and the second opening 455 can be formed as rectangles. On the plane of the display device 1000, the size of the first opening 195 can be smaller than the size of the second opening 455. In this embodiment, the first opening 195 can be disposed inside the second opening 455. The corners of each of the first opening 195 and the second opening 455 can be chamfered into curves. However, the corners of each of the first opening 195 and the second opening 455 can have any other suitable shape or one or more. For example, the corners of the first opening 195 and the second opening 455 can be chamfered into straight lines.

[0064] The first opening 195 may include a first side 195a, a second side 195b adjacent to the first side 195a in a clockwise direction, a third side 195c adjacent to the second side 195b in a clockwise direction, and a fourth side 195d adjacent to the third side 195c in a clockwise direction. The fourth side 195d of the first opening 195 may be adjacent to the first side 195a. The second opening 455 may include a first side 455a, a second side 455b adjacent to the first side 455a in a clockwise direction, a third side 455c adjacent to the second side 455b in a clockwise direction, and a fourth side 455d adjacent to the third side 455c in a clockwise direction. The fourth side 455d of the second opening 455 may be adjacent to the first side 455a. The first side 195a of the first opening 195 may be adjacent to or close to the first side 455a of the second opening 455, and they may be parallel or substantially parallel to each other. The second side 195b of the first opening 195 may be adjacent to or close to the second side 455b of the second opening 455, and they may be parallel or substantially parallel to each other. The third side 195c of the first opening 195 may be adjacent to or close to the third side 455c of the second opening 455, and they may be parallel or substantially parallel to each other. The fourth side 195d of the first opening 195 may be adjacent to or close to the fourth side 455d of the second opening 455, and they may be parallel or substantially parallel to each other.

[0065] In this embodiment, the shortest interval distance between the first side 195a of the first opening 195 and the second opening 455 is defined as the first interval distance S1. That is, the first interval distance S1 refers to the shortest interval distance (i.e., the straight-line interval distance) between the first side 195a of the first opening 195 and the first side 455a of the second opening 455. Furthermore, the shortest interval distance between the second side 195b of the first opening 195 and the second opening 455 is defined as the second interval distance S2. That is, the second interval distance S2 refers to the shortest interval distance (i.e., the straight-line interval distance) between the second side 195b of the first opening 195 and the second side 455b of the second opening 455. Additionally, the shortest interval distance between the third side 195c of the first opening 195 and the second opening 455 is defined as the third interval distance S3. That is, the third interval distance S3 refers to the shortest interval distance (i.e., the straight-line interval distance) between the third side 195c of the first opening 195 and the third side 455c of the second opening 455. Furthermore, the shortest interval distance between the fourth side 195d of the first opening 195 and the second opening 455 is defined as the fourth interval distance S4. That is, the fourth interval distance S4 refers to the shortest interval distance (i.e., the straight-line interval distance) between the fourth side 195d of the first opening 195 and the fourth side 455d of the second opening 455.

[0066] For any given pixel PX, the shortest interval between one side of the first opening 195 and the second opening 455 can be different from the shortest interval between the other side of the first opening 195 and the second opening 455. For example, the first interval S1 and the second interval S2 at the red pixel R can be different from each other. Additionally, the first interval S1 and the third interval S3 at the green pixel G can be different from each other. Furthermore, the first interval S1 and the second interval S2 at the blue pixel B can be different from each other.

[0067] The first interval distance S1, the second interval distance S2, the third interval distance S3 and the fourth interval distance S4 within each pixel PX will be described in detail later.

[0068] Red pixel R may include a first red pixel R1 and a second red pixel R2. The first opening 195 located at the first red pixel R1 and the first opening 195 located at the second red pixel R2 may have the same or a similar shape. Although the second opening 455 located at the first red pixel R1 may have a different orientation than the second opening 455 located at the second red pixel R2, the second opening 455 located at the first red pixel R1 and the second opening 455 located at the second red pixel R2 may have the same or a similar shape.

[0069] Green pixel G may include a first green pixel G1, a second green pixel G2, a third green pixel G3, and a fourth green pixel G4. The first opening 195 located at the first green pixel G1 and the first opening 195 located at the fourth green pixel G4 may have the same or a similar shape. The second opening 455 located at the first green pixel G1 and the second opening 455 located at the fourth green pixel G4 may have the same or a similar shape. The first opening 195 located at the second green pixel G2 and the first opening 195 located at the third green pixel G3 may have the same or a similar shape. The second opening 455 located at the second green pixel G2 and the second opening 455 located at the third green pixel G3 may have the same or a similar shape. Although the orientation of the first opening 195 located at the first green pixel G1 may differ from that of the first opening 195 located at the second green pixel G2, the first opening 195 located at the first green pixel G1 and the first opening 195 located at the second green pixel G2 may have the same or a similar shape. Although the orientation of the second opening 455 located at the first green pixel G1 may be different from that of the second opening 455 located at the second green pixel G2, the second opening 455 located at the first green pixel G1 and the second opening 455 located at the second green pixel G2 have the same shape or similar shape.

[0070] Blue pixel B may include a first blue pixel B1 and a second blue pixel B2. The first opening 195 located at the first blue pixel B1 and the first opening 195 located at the second blue pixel B2 may have the same or a similar shape. Although the orientation of the second opening 455 located at the first blue pixel B1 may differ from that of the second opening 455 located at the second blue pixel B2, the second opening 455 located at the first blue pixel B1 and the second opening 455 located at the second blue pixel B2 may have the same or a similar shape.

[0071] In one or more embodiments, for each pixel PX, the first opening 195 and the second opening 455 are substantially formed in a rectangular shape, but they may have different sizes, which will be described in detail later.

[0072] Next, refer to Figures 2 to 6 The structure of the display device according to the exemplary embodiments will be described in detail.

[0073] Figure 2 This is a perspective view of a display device according to an exemplary embodiment. Figure 3 yes Figure 2 The image depicts a top view of a certain area of ​​the display device. Figure 4 yes Figure 3A sectional view taken along line IV-IV'. Figure 5 This is a schematic top plan view of a plurality of first electrodes and a plurality of first openings in a display device according to an exemplary embodiment. Figure 6 This is a cross-sectional view showing the reflection of light in a display device according to an exemplary embodiment.

[0074] like Figure 2 As shown, the display device 1000 according to an exemplary embodiment includes a display portion DP and a touch portion TP. In this embodiment, for ease of explanation, the display portion DP and the touch portion TP are shown as being formed separately from each other; however, the display portion DP and the touch portion TP of the display device 1000 are integrally formed. In one embodiment, the display device 1000 may have an on-cell structure in which the touch portion TP is directly disposed on the display portion DP without a separate substrate. However, this disclosure is not limited thereto; the display device 1000 may have an in-cell structure in which the touch portion TP is disposed inside the display portion DP, or it may have an add-on structure in which the touch portion TP is formed as a separate panel attached to the display portion DP.

[0075] The display unit DP can be divided into a display area DA and a non-display area NDA. The display unit DP includes multiple pixels PX arranged in a matrix format. The multiple pixels PX are shown as forming an approximately quadrilateral shape, but are not limited to this, and the multiple pixels PX can have various forms.

[0076] The touch unit TP may be on the display unit DP. The touch unit TP includes at least one sensing electrode SE for detecting whether a touch has been made and for determining the touch coordinates.

[0077] like Figure 3 As shown, the sensing electrode SE includes a first sensing electrode SE1 extending in a first direction D1 and a second sensing electrode SE2 extending in a second direction D2 intersecting the first direction D1.

[0078] The first sensing electrode SE1 and the second sensing electrode SE2 can be arranged or constructed around the pixel PX on a plane.

[0079] For example, a pixel PX can be surrounded on a plane by a first sensing electrode SE1 and a second sensing electrode SE2. However, this disclosure is not limited to this; the first sensing electrode SE1 and the second sensing electrode SE2 can surround four pixels PX forming a pixel group on a plane. The accuracy of touch sensing can vary depending on the density of the first sensing electrode SE1 and the second sensing electrode SE2.

[0080] In addition, the first sensing electrode SE1 and the second sensing electrode SE2 are formed in the shape of a grid electrode on a plane, but this disclosure is not limited thereto, and each of the first sensing electrode SE1 and the second sensing electrode SE2 may have a planar electrode shape.

[0081] The first sensing electrode SE1 and the second sensing electrode SE2 may each comprise a metal or a transparent conductive material. Such a transparent conductive material may include at least one of transparent conductive oxides (TCOs) (such as indium tin oxide (ITO), indium zinc oxide (IZO), and zinc oxide (ZnO)), carbon nanotubes (CNTs), and graphene.

[0082] The first sensing electrode SE1 can be electrically connected to the first routing wiring 510, and the second sensing electrode SE2 can be electrically connected to the second routing wiring 520. Both the first routing wiring 510 and the second routing wiring 520 can be connected to the touch driver 500. In this embodiment, the first routing wiring 510 and the second routing wiring 520 are shown connected to a single touch driver 500; however, this disclosure is not limited thereto, and the first routing wiring 510 and the second routing wiring 520 can be connected to separate touch drivers 500.

[0083] The touch driver 500 can determine whether a touch has occurred and determine the touch coordinates by inputting a drive signal to the first sensing electrode SE1 and using the amount of capacitance or voltage change measured by the second sensing electrode SE2. The touch driver 500 can be located directly on the substrate as an integrated circuit (IC), or it can be fabricated in a separate structure.

[0084] like Figure 4 As shown, the display device 1000 according to an exemplary embodiment includes a display unit DP and a touch unit TP on the display unit DP.

[0085] The display unit DP includes a substrate 110, a driving circuit 130, a partition wall 190, a light-emitting element 210, and a thin-film encapsulation layer 301.

[0086] The substrate 110 can be made of insulating materials such as glass, quartz, ceramics, and plastics. The substrate 110 can be flexible.

[0087] A buffer layer 120 may be disposed on the substrate 110. The buffer layer 120 may comprise an inorganic or organic layer and may be formed of a single layer or multiple layers. The buffer layer 120 prevents unwanted components such as impurities and / or moisture from penetrating into the drive circuit 130 or the light-emitting element 210, and also flattens the surface. However, the buffer layer 120 may be omitted.

[0088] The driving circuit 130 may be disposed on the buffer layer 120. The driving circuit 130 includes a plurality of thin-film transistors 20 and capacitors 80, and can drive the light-emitting element 210. In addition, the driving circuit 130 may also include a gate line (not shown) extending in one direction and a data line 171 and a common power line 172 that cross the gate line in an insulated manner.

[0089] The light-emitting element 210 displays an image by emitting light according to a drive signal sent from the drive circuit 130.

[0090] The display device 1000 according to an exemplary embodiment may have a 2Tr-1Cap structure comprising two thin-film transistors 20 and one capacitor 80 in a single pixel PX, or it may have a structure comprising three or more thin-film transistors 20 and two or more capacitors 80 in a single pixel PX. The structure of the thin-film transistors 20 and capacitors 80 constituting a pixel PX can be modified in various ways.

[0091] Capacitor 80 may include a pair of capacitor plates 158 and 178 and an interlayer insulating layer 145 therebetween. In one embodiment, the interlayer insulating layer 145 is a dielectric material. Capacitance is determined by the charge stored in capacitor 80 and the voltage difference between the two capacitor plates 158 and 178.

[0092] The thin-film transistor 20 may include a semiconductor 132, a gate electrode 155, a source electrode 176, and a drain electrode 177. The semiconductor 132 and the gate electrode 155 may be insulated from each other by a gate insulating layer 140. The thin-film transistor 20 may apply driving power to a first electrode 211 for light emission from the emitting layer 212 of the light-emitting element 210 in a selected pixel PX. In this embodiment, the gate electrode 155 may be connected to a capacitor plate 158, the source electrode 176 and another capacitor plate 178 may be connected to a common power line 172, and the drain electrode 177 may be connected to the first electrode 211 of the light-emitting element 210 through an opening in the planarization layer 146.

[0093] Planarization layer 146 may be on interlayer insulating layer 145. Planarization layer 146 is made of insulating material and can protect drive circuit 130. Planarization layer 146 and interlayer insulating layer 145 may include the same material.

[0094] The first electrode 211 may be on the planarization layer 146. The first electrode 211 may be a pixel electrode and may be an anode. The first electrode 211 may be conductive and may be a transmissive electrode, a semi-transmissive electrode, or a reflective electrode.

[0095] The partition wall 190 separating the light-emitting areas can be located on the planarization layer 146 and the first electrode 211. In this embodiment, the light-emitting area is also referred to as the pixel area. The partition wall 190 can include an organic polymer material. For example, the partition wall 190 can include at least one of polyimide resin, polyacrylamide resin, polyethylene terephthalate (PET) resin, and polyethylene naphthalate (PEN) resin.

[0096] The partition wall 190 includes a first opening 195. The first opening 195 defines the portion of the first electrode 211 not covered by the partition wall 190. The first opening 195 may overlap with the first electrode 211. The edge of the first electrode 211 may overlap with the partition wall 190.

[0097] Reference Figure 5 The partition wall 190 includes a plurality of first openings 195 corresponding to a plurality of pixels PX. The plurality of pixels PX may include a red pixel R, a green pixel G, and a blue pixel B. In this embodiment, the light-emitting element 210 of the red pixel R may include a red emitting layer, the light-emitting element 210 of the green pixel G may include a green emitting layer, and the light-emitting element 210 of the blue pixel B may include a blue emitting layer.

[0098] Each of the plurality of first openings 195 may have a shape similar to that of the first electrode 211 on the plane of the display device 1000. For example, the first openings 195 and the first electrode 211 may be formed as polygons on the plane of the display device 1000. In this embodiment, the corners of the first openings 195 and the first electrode 211 may be chamfered. However, the shapes of the corners of the first openings 195 and the first electrode 211 are not limited to this and may be modified in various ways.

[0099] In this embodiment, the plurality of first electrodes 211 corresponding to the red pixel R, green pixel G, and blue pixel B, respectively, can have different sizes on the plane of the display device 1000. Similarly, the plurality of first openings 195 corresponding to the red pixel R, green pixel G, and blue pixel B, respectively, can have different sizes on the plane of the display device 1000. For example, on the plane of the display device 1000, the first opening 195 and first electrode 211 corresponding to the red pixel R can be larger in size than the first opening 195 and first electrode 211 corresponding to the green pixel G. Furthermore, on the plane of the display device 1000, the first opening 195 and first electrode 211 corresponding to the red pixel R can be smaller in size than the first opening 195 and first electrode 211 corresponding to the blue pixel B, or similar in size to the first opening 195 and first electrode 211 corresponding to the blue pixel B. However, this disclosure is not limited thereto, and each of the first openings 195 and each of the first electrodes 211 can have various shapes and sizes.

[0100] Furthermore, the display device 1000 according to the exemplary embodiment may have a pentile structure (e.g., an RG-BG arrangement of subpixels). For example, a plurality of first electrodes 211 corresponding to the green emitting layer may be arranged in the Nth row at predetermined intervals, and the first electrodes 211 corresponding to the red emitting layer and the first electrodes 211 corresponding to the blue emitting layer may be alternately arranged in adjacent N+1th rows. Similarly, a plurality of first electrodes 211 corresponding to the green emitting layer may be arranged in adjacent N+2th rows at predetermined intervals, and the first electrodes 211 corresponding to the blue emitting layer and the first electrodes 211 corresponding to the red emitting layer may be alternately arranged in adjacent N+3th rows.

[0101] Furthermore, the first electrode 211 corresponding to the plurality of green emitting layers arranged in the Nth row can be alternately (e.g., laterally staggered) moved with the first electrodes 211 corresponding to the plurality of red and blue emitting layers in the N+1th row. For example, the first electrodes 211 corresponding to the red and blue emitting layers are alternately arranged in the Mth column, and the first electrodes 211 corresponding to the plurality of green emitting layers can be arranged at predetermined intervals in adjacent M+1th columns. Similarly, the first electrodes 211 corresponding to the blue and red emitting layers are alternately arranged in adjacent M+2th columns, and the first electrodes 211 corresponding to the plurality of green emitting layers can be arranged at predetermined intervals in adjacent M+3th columns. In one embodiment, the plurality of first electrodes 211 can be repeatedly arranged on the substrate 110 in the structure described above.

[0102] Return to reference Figure 4 The emitting layer 212 may be on the first electrode 211. The emitting layer 212 is located in the first opening 195 of the partition wall 190 and may be stacked with the first electrode 211. The emitting layer 212 includes a light-emitting material. The light-emitting material may be an inorganic or organic material such as quantum dots. Additionally, the emitting layer 212 may include a host and a light-emitting dopant.

[0103] The second electrode 213 can be disposed on the emitting layer 212. The second electrode 213 can be a common electrode or a cathode. The second electrode 213 can be a transmission electrode, a semi-transmission electrode, or a reflection electrode.

[0104] Although not shown, at least one of the hole injection layer (HIL) and hole transport layer (HTL) may be disposed between the first electrode 211 and the emitter layer 212, and at least one of the electron transport layer (ETL) and electron injection layer (EIL) may be disposed between the emitter layer 212 and the second electrode 213.

[0105] A thin-film encapsulation layer 301 can be disposed on the second electrode 213 to protect the light-emitting element 210. The thin-film encapsulation layer 301 can prevent moisture or oxygen from penetrating into the light-emitting element 210.

[0106] The thin-film encapsulation layer 301 may include at least one of inorganic layers 310 and 330 and at least one organic layer 320. The thin-film encapsulation layer 301 is shown to include two inorganic layers 310 and 330 and one organic layer 320, but this disclosure is not limited thereto. Alternatively, an encapsulation substrate may be provided instead of the thin-film encapsulation layer 301. In this embodiment, a sealing member may be located between the substrate and the encapsulation substrate.

[0107] Inorganic layers 310 and 330 may comprise at least one inorganic material selected from Al2O3, TiO2, ZrO, SiO2, AlON, AlN, SiON, Si3N4, ZnO, and Ta2O5. Organic layer 320 may comprise a polymeric material. The polymeric material may include acrylamide resins, polyimides, epoxy resins, polyethylene, etc.

[0108] The dense inorganic layers 310 and 330 can inhibit or reduce the permeation of moisture or oxygen. In addition to serving as a buffer layer to reduce stress between the inorganic layers 310 and 330, the organic layer 320 also has planarization properties, so the top surface of the thin film encapsulation layer 301 can be planarized by the organic layer 320.

[0109] The thin-film encapsulation layer 301 may have a thickness of about 5 μm to about 50 μm. However, the thickness of the thin-film encapsulation layer 301 is not limited to this.

[0110] The display unit DP, comprising a substrate 110, a driving circuit 130, a partition wall 190, a light-emitting element 210, and a thin-film encapsulation layer 301, can be formed as an organic light-emitting panel. However, the type of display unit DP is not limited to this, and the display unit DP can be formed from various types of panels. For example, the display unit DP can be formed from a liquid crystal display panel, an electrophoretic display panel, an electrowetting display panel, a micro light-emitting diode (micro-LED) display panel, a quantum dot light-emitting diode (QLED) display panel, a quantum dot organic light-emitting diode (OLED) (QD-OLED) display panel, etc.

[0111] A first sensing electrode SE1 may be disposed on the thin-film encapsulation layer 301. A first insulating layer 410 may be disposed on the first sensing electrode SE1 and the thin-film encapsulation layer 301. The first insulating layer 410 may include at least one of an inorganic layer and an organic layer. The inorganic layer may include at least one of silicon oxide, silicon nitride, and silicon oxynitride. The organic layer may include a polymeric material. A second sensing electrode SE2 may be disposed on the first insulating layer 410.

[0112] In the above description, the touch portion TP is described as including a first sensing electrode SE1 and a second sensing electrode SE2 on different layers, but this disclosure is not limited thereto. For example, the touch portion TP may include a first sensing electrode SE1 and a second sensing electrode SE2 on the same layer and connected by a bridging electrode.

[0113] The second insulating layer 420 may be on the second sensing electrode SE2 and the first insulating layer 410. The second insulating layer 420 may include at least one of an organic layer and an inorganic layer.

[0114] The low-refractive-index layer 450 is located on the second insulating layer 420. The low-refractive-index layer 450 may comprise a light-transmitting organic material having a low refractive index. For example, the low-refractive-index layer 450 may comprise at least one of acrylic resin, polyimide resin, polyamide resin, and Alq3 (tris(8-hydroxyquinoline)aluminum). The low-refractive-index layer 450 may have a relatively low refractive index compared to the high-refractive-index layer 470. For example, the low-refractive-index layer 450 may have a refractive index of about 1.40 to about 1.59.

[0115] The low-refractive-index layer 450 includes a second opening 455. The second opening 455 defines a portion of the second insulating layer 420 that is not covered by the low-refractive-index layer 450. The second opening 455 may be superimposed on the first opening 195.

[0116] The spacing S between the first opening 195 and the second opening 455 refers to the shortest distance (i.e., the straight-line spacing) between the edges of the first opening 195 and the second opening 455. The edge of the first opening 195 refers to the point where the partition wall 190 contacts the first electrode 211. The edge of the second opening 455 refers to the point where the low-refractive layer 450 contacts the second insulating layer 420. The spacing S may include the first spacing S1, the second spacing S2, the third spacing S3, and the fourth spacing S4 defined above.

[0117] A high-refractive-index layer 470 may be present on the second insulating layer 420 and the low-refractive-index layer 450. The high-refractive-index layer 470 may comprise a light-transmitting organic material with a high refractive index. The high-refractive-index layer 470 may have a relatively larger refractive index than the low-refractive-index layer 450. For example, the high-refractive-index layer 470 may have a refractive index of about 1.60 to about 1.80.

[0118] The high-refractive-index layer 470 may be located within the second opening 455 of the low-refractive-index layer 450. In this embodiment, the high-refractive-index layer 470 contacts the side surface of the low-refractive-index layer 450. Alternatively, the high-refractive-index layer 470 may also be located on the top surface of the low-refractive-index layer 450 to contact the top surface of the low-refractive-index layer 450.

[0119] Although not shown, a polarization layer including a linear polarizer, a retarder, etc., may be on the touch portion TP. Additionally, a cover window protecting the touch portion TP and the display portion DP may be on the touch portion TP. In this embodiment, an adhesive layer may be located between the polarization layer and the cover window.

[0120] The touch portion TP includes a low-refractive-index layer 450 containing a second opening 455 and a high-refractive-index layer 470 within the second opening 455 of the low-refractive-index layer 450, thereby improving the front visibility and luminous efficiency of the display device 1000. Specifically, at least some of the light emitted from the light-emitting element 210 can be totally internally reflected at the interface between the low-refractive-index layer 450 and the high-refractive-index layer 470, allowing the light to be concentrated on the front of the display device 1000.

[0121] Reference Figure 6 This will be described in detail. Figure 6 The reflection of light at the interface between the low-refractive-index layer 450 and the high-refractive-index layer 470 is shown. Light L generated from the emitting layer 212 of the light-emitting element 210 can be emitted in various directions and can enter the touch portion TP at various incident angles. In this case, at least a portion of the light L incident on the high-refractive-index layer 470 of the touch portion TP is reflected at the interface between the low-refractive-index layer 450 and the high-refractive-index layer 470. In one or more embodiments, the light L incident on the high-refractive-index layer 470 can be totally internally reflected at the interface between the low-refractive-index layer 450 and the high-refractive-index layer 470 and emitted from the front of the display device 1000. That is, while the light L incident on the high-refractive-index layer 470, which has a relatively high refractive index, travels towards the low-refractive-index layer 450, which has a relatively low refractive index, total internal reflection can occur at the interface between the low-refractive-index layer 450 and the high-refractive-index layer 470.

[0122] In one or more embodiments, the interface between the low-refractive layer 450 and the high-refractive layer 470 may form an angle of about 40 degrees to about 70 degrees relative to a straight line parallel to the substrate 110. In the illustrated embodiment, the angle between the low-refractive layer 450 and the high-refractive layer 470 is opposite to the second opening 455 of the low-refractive layer 450. The interface between the low-refractive layer 450 and the high-refractive layer 470 may be a side surface of the low-refractive layer 450 including the second opening 455 (e.g., an angled or inclined side surface). That is, the side surface of the low-refractive layer 450 may form an angle of about 40 degrees to about 70 degrees relative to the top surface of the second insulating layer 420.

[0123] When the angle is less than approximately 40 degrees, most of the light L does not enter the interface between the low-refractive layer 450 and the high-refractive layer 470, and therefore total internal reflection does not occur (for example, less than a majority of the light L can be incident on the interface between the low-refractive layer 450 and the high-refractive layer 470). Conversely, when the angle is greater than approximately 70 degrees, the light L that is totally internally reflected from the interface between the low-refractive layer 450 and the high-refractive layer 470 will not be emitted to the front of the display device 1000. Therefore, the interface between the low-refractive layer 450 and the high-refractive layer 470 forms an angle of approximately 40 to approximately 70 degrees relative to a straight line parallel to the substrate 110, such that the light L incident on the interface between the low-refractive layer 450 and the high-refractive layer 470 is totally internally reflected and thus concentrated on the front side of the display device 1000. In this way, compared to other comparable devices that do not have these features, the light output efficiency at the front of the display device 1000 can be improved.

[0124] Return to reference Figure 1 This will describe the shape of each of the first opening 195 and the second opening 455 at each pixel PX, as well as the spacing S between the first opening 195 and the second opening 455. Further reference will be made in the description relating to the value of the spacing S. Figure 7 . Figure 7 It is a graph showing the luminous efficiency relative to the distance between the first and second openings.

[0125] Red pixel R may include a first red pixel R1 and a second red pixel R2. A first opening 195 located at the first red pixel R1 and the second red pixel R2 may be formed in a substantially square shape. That is, the first side 195a, the second side 195b, the third side 195c, and the fourth side 195d of the first opening 195 located at each of the first red pixel R1 and the second red pixel R2 may be substantially the same in length. A second opening 455 located at the first red pixel R1 and the second red pixel R2 may be formed in a substantially rectangular shape. Two opposite sides of the second opening 455 may be substantially the same in length. The first side 455a and the third side 455c of the second opening 455 may be substantially the same in length. The second side 455b and the fourth side 455d of the second opening 455 may be substantially the same in length.

[0126] The lengths of the first side 455a and the third side 455c of the second opening 455 located at the first red pixel R1 can be shorter than the lengths of its second side 455b and the fourth side 455d. Therefore, at the first red pixel R1, the first spacing distance S1 and the third spacing distance S3 can be different from the second spacing distance S2 and the fourth spacing distance S4. At the first red pixel R1, the first spacing distance S1 can be substantially the same as the third spacing distance S3, and the second spacing distance S2 can be substantially the same as the fourth spacing distance S4. At the first red pixel R1, the first spacing distance S1 can be larger than the second spacing distance S2, and the first spacing distance S1 can be larger than the fourth spacing distance S4. At the first red pixel R1, the third spacing distance S3 can be larger than the second spacing distance S2, and the third spacing distance S3 can be larger than the fourth spacing distance S4.

[0127] The lengths of the first side 455a and the third side 455c of the second opening 455 located at the second red pixel R2 can be longer than the lengths of its second side 455b and the fourth side 455d. Therefore, at the second red pixel R2, the first spacing distance S1 and the third spacing distance S3 can be different from the second spacing distance S2 and the fourth spacing distance S4. At the second red pixel R2, the first spacing distance S1 can be substantially the same as the third spacing distance S3, and the second spacing distance S2 can be substantially the same as the fourth spacing distance S4. At the second red pixel R2, the first spacing distance S1 can be smaller than the second spacing distance S2, and the third spacing distance S3 can be smaller than the fourth spacing distance S4. At the second red pixel R2, the third spacing distance S3 can be smaller than the second spacing distance S2, and the third spacing distance S3 can be smaller than the fourth spacing distance S4.

[0128] The second opening 455 located at the first red pixel R1 can be formed as a rectangle extending along the first direction D1, and the second opening 455 located at the second red pixel R2 can be formed as a rectangle extending along the second direction D2. In the illustrated embodiment, the second direction D2 is perpendicular to the first direction D1. Figure 1 The diagram shows a first red pixel R1 and a second red pixel R2, but the display device 1000 may include a plurality of first red pixels R1 and a plurality of second red pixels R2. In one or more embodiments, the number of first red pixels R1 may be the same as or substantially the same as the number of second red pixels R2.

[0129] Reference Figure 7 When the interval S between the first opening 195 and the second opening 455 has a predetermined value, the luminous efficiency becomes the maximum value, and when the interval distance is less than or greater than the predetermined value, the luminous efficiency decreases. Figure 7 In the graph, it is assumed that the distance S between the first opening 195 and the second opening 455 is constant. The horizontal axis represents the distance S between the first opening 195 and the second opening 455, and the vertical axis represents the luminous efficiency. Figure 7 In this context, 100% luminous efficiency refers to a configuration in which the display device 1000 does not include the high-refractive-index layer 470 and the low-refractive-index layer 450 does not include the second opening 455. That is, Figure 7 The horizontal line corresponding to 100% luminous efficiency indicates a configuration in the display device 1000 where the low-refractive layer 450 is unpatterned and formed on the entire substrate 110. The luminous efficiency is at its maximum when the spacing S between the first opening 195 and the second opening 455 is approximately 1.3 μm, and is lower than the maximum when the spacing S between the first opening 195 and the second opening 455 is less than or greater than approximately 1.3 μm. The spacing S between the first opening 195 and the second opening 455 that produces the maximum luminous efficiency can be defined as the preferred spacing distance. The preferred spacing distance can vary depending on variations in the process design. Furthermore, the preferred spacing distance can be different for each of the red pixel R, green pixel G, and blue pixel B.

[0130] At the first red pixel R1, the first spacing distance S1 and the third spacing distance S3 can be larger than the preferred spacing distance. At the first red pixel R1, the second spacing distance S2 and the fourth spacing distance S4 can be smaller than the preferred spacing distance. Furthermore, at the second red pixel R2, the first spacing distance S1 and the third spacing distance S3 can be smaller than the preferred spacing distance. At the second red pixel R2, the second spacing distance S2 and the fourth spacing distance S4 can be larger than the preferred spacing distance.

[0131] For example, at the first red pixel R1, the first spacing distance S1 and the third spacing distance S3 can be approximately 1.8 μm, and the second spacing distance S2 and the fourth spacing distance S4 can be approximately 0.8 μm. In this embodiment, at the second red pixel R2, the first spacing distance S1 and the third spacing distance S3 can be approximately 0.8 μm, and the second spacing distance S2 and the fourth spacing distance S4 can be approximately 1.8 μm. However, at the first red pixel R1 and the second red pixel R2, the ranges of the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 are not limited to these values ​​and can be varied. Optionally, at the first red pixel R1, the first spacing distance S1 and the third spacing distance S3 can be approximately 2.3 μm, and the second spacing distance S2 and the fourth spacing distance S4 can be approximately 0.3 μm. In this embodiment, at the second red pixel R2, the first spacing distance S1 and the third spacing distance S3 can be approximately 0.3 μm, and the second spacing distance S2 and the fourth spacing distance S4 can be approximately 2.3 μm. Optionally, at the first red pixel R1, the first spacing distance S1 and the third spacing distance S3 can be approximately 1.4 μm, and the second spacing distance S2 and the fourth spacing distance S4 can be approximately 1.2 μm. In this embodiment, at the second red pixel R2, the first spacing distance S1 and the third spacing distance S3 can be approximately 1.2 μm, and the second spacing distance S2 and the fourth spacing distance S4 can be approximately 1.4 μm.

[0132] At the first red pixel R1 and the second red pixel R2, the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 can each differ from the preferred spacing distance (e.g., 1.3 μm) by about 0.1 μm or more and less than about 1.0 μm. That is, at least one of the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 can be about 1.4 μm or more and less than about 2.3 μm, and the other spacing distances among the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 can be about 0.3 μm or more and less than about 1.2 μm. Therefore, at the first red pixel R1 and the second red pixel R2, the difference between the first spacing distance S1 and the second spacing distance S2 can be about 0.2 μm or more and less than about 2.0 μm. At the first red pixel R1 and the second red pixel R2, the difference between the first spacing distance S1 and the fourth spacing distance S4 can be approximately 0.2 μm or greater and less than approximately 2.0 μm. At the first red pixel R1 and the second red pixel R2, the difference between the third spacing distance S3 and the second spacing distance S2 can be approximately 0.2 μm or greater and less than approximately 2.0 μm. At the first red pixel R1 and the second red pixel R2, the difference between the third spacing distance S3 and the fourth spacing distance S4 can be approximately 0.2 μm or greater and less than approximately 2.0 μm.

[0133] As described in detail below, in an exemplary embodiment, the spacing distances S1-S4 are designed to be different from each other at a pixel PX of the display device 1000, thereby preventing or at least reducing changes in luminous efficiency even if errors occur in the manufacturing process of the display device 1000. In the following, reference will be made to... Figures 8 to 11 The principle of compensating for changes in luminous efficiency when errors occur in the process will now be described.

[0134] Figure 8 This illustrates the change in luminous efficiency in a display device according to an exemplary embodiment where some layers are patterned smaller than the design size. Figure 9 The diagram illustrates the change in luminous efficiency in a display device according to an exemplary embodiment when some layers are patterned to be larger than the design size. Figure 10 The change in luminous efficiency is shown when some layers of a display device according to an exemplary embodiment are offset to the left more than designed. Figure 11 The change in luminous efficiency is shown when some layers of a display device according to an exemplary embodiment are offset to the right more than designed. Figures 9-11 In the diagram, solid arrows indicate an increase in luminous efficiency, while dashed arrows indicate a decrease in luminous efficiency.

[0135] like Figure 8As shown, at the first red pixel R1 and the second red pixel R2 of the display device 1000 according to an exemplary embodiment, the first opening 195 can be patterned as designed, and the second opening 455 can be patterned to be smaller than designed. In this embodiment, at the first red pixel R1 and the second red pixel R2, the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 are reduced.

[0136] At the first red pixel R1, the first spacing distance S1 is designed to be larger than the preferred spacing distance, so the luminous efficiency increases as the first spacing distance S1 decreases. Since the second spacing distance S2 is designed to be smaller than the preferred spacing distance at the first red pixel R1, the luminous efficiency decreases as the second spacing distance S2 decreases. The third spacing distance S3 is designed to be larger than the preferred spacing distance at the first red pixel R1, so the luminous efficiency increases as the third spacing distance S3 decreases. The fourth spacing distance S4 is designed to be smaller than the preferred spacing distance at the first red pixel R1, so the luminous efficiency decreases as the fourth spacing distance S4 decreases. In one or more embodiments, the increase in luminous efficiency as the first spacing distance S1 and the third spacing distance S3 decreases is substantially equal to the decrease in luminous efficiency as the second spacing distance S2 and the fourth spacing distance S4 decreases, thereby compensating for changes in luminous efficiency (e.g., causing changes in luminous efficiency to cancel each other out). That is, even if errors occur in the manufacturing process of the display device 1000 (e.g., errors occur when manufacturing the second opening 455 at the first red pixel R1), changes in luminous efficiency can be prevented. Therefore, if the second opening 455 at the first red pixel R1 is manufactured to be smaller than the designed size, the following configuration is made to maintain a constant or substantially constant luminous efficiency of the display device 1000: the first spacing distance S1 and the third spacing distance S3 are designed to be larger than the preferred spacing distance and the second spacing distance S2 and the fourth spacing distance S4 are designed to be smaller than the preferred spacing distance.

[0137] At the second red pixel R2, the first spacing distance S1 is designed to be smaller than the preferred spacing distance, thus the luminous efficiency decreases as the first spacing distance S1 decreases. The second spacing distance S2 is designed to be larger than the preferred spacing distance at the second red pixel R2, thus the luminous efficiency increases as the second spacing distance S2 decreases. The third spacing distance S3 is designed to be smaller than the preferred spacing distance at the second red pixel R2, thus the luminous efficiency decreases as the third spacing distance S3 decreases. The fourth spacing distance S4 is designed to be larger than the preferred spacing distance at the second red pixel R2, thus the luminous efficiency increases as the fourth spacing distance S4 decreases. In one or more embodiments, the decrease in luminous efficiency as the first spacing distance S1 and the third spacing distance S3 decreases is substantially equal to the increase in luminous efficiency as the second spacing distance S2 and the fourth spacing distance S4 decreases, thereby compensating for the change in luminous efficiency (e.g., causing the changes in luminous efficiency to cancel each other out). That is, even if an error occurs in the manufacturing process of the display device 1000 (e.g., an error occurs when manufacturing the second opening 455 at the second red pixel R2), a change in luminous efficiency can be prevented. Therefore, if the size of the second opening 455 at the second red pixel R2 is manufactured to be smaller than the designed size, the following configuration is made to maintain a constant or substantially constant luminous efficiency of the display device 1000: the first spacing distance S1 and the third spacing distance S3 are designed to be smaller than the preferred spacing distance and the second spacing distance S2 and the fourth spacing distance S4 are designed to be larger than the preferred spacing distance.

[0138] like Figure 9 As shown, at the first red pixel R1 and the second red pixel R2 of the display device 1000 according to an exemplary embodiment, the first opening 195 can be patterned as designed, and the second opening 455 can be patterned to be larger than designed. In this embodiment, the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 at the first red pixel R1 and the second red pixel R2 are increased.

[0139] Because the first spacing distance S1 is designed to be larger than the preferred spacing distance at the first red pixel R1, the luminous efficiency decreases as the first spacing distance S1 increases. Because the second spacing distance S2 is designed to be smaller than the preferred spacing distance at the first red pixel R1, the luminous efficiency increases as the second spacing distance S2 increases. Because the third spacing distance S3 is designed to be larger than the preferred spacing distance at the first red pixel R1, the luminous efficiency decreases as the third spacing distance S3 increases. Because the fourth spacing distance S4 is designed to be smaller than the preferred spacing distance at the first red pixel R1, the luminous efficiency increases as the fourth spacing distance S4 increases. In one or more embodiments, the decrease in luminous efficiency due to the increase of the first spacing distance S1 and the third spacing distance S3 is substantially equal to the increase in luminous efficiency due to the increase of the second spacing distance S2 and the fourth spacing distance S4, thereby compensating for the change in luminous efficiency (e.g., causing the change in luminous efficiency to cancel each other out). That is, even if an error occurs in the manufacturing process of the display device 1000 (e.g., an error occurs when manufacturing the second opening 455 at the first red pixel R1), a change in luminous efficiency can be prevented. Therefore, if the size of the second opening 455 at the first red pixel R1 is manufactured to be larger than the designed size, the following configuration is made to maintain a constant or substantially constant luminous efficiency of the display device 1000: the first spacing distance S1 and the third spacing distance S3 are designed to be larger than the preferred spacing distance and the second spacing distance S2 and the fourth spacing distance S4 are designed to be smaller than the preferred spacing distance.

[0140] At the second red pixel R2, the first spacing distance S1 is designed to be smaller than the preferred spacing distance, so the luminous efficiency increases as the first spacing distance S1 increases. The second spacing distance S2 is designed to be larger than the preferred spacing distance at the second red pixel R2, so the luminous efficiency decreases as the second spacing distance S2 increases. The third spacing distance S3 is designed to be smaller than the preferred spacing distance at the second red pixel R2, so the luminous efficiency increases as the third spacing distance S3 increases. The fourth spacing distance S4 is designed to be larger than the preferred spacing distance at the second red pixel R2, so the luminous efficiency decreases as the fourth spacing distance S4 increases. In one or more embodiments, the increase in luminous efficiency due to the increase of the first spacing distance S1 and the third spacing distance S3 is substantially equal to the decrease in luminous efficiency due to the increase of the second spacing distance S2 and the fourth spacing distance S4, thereby compensating for the change in luminous efficiency (e.g., causing the changes in luminous efficiency to cancel each other out). That is, even if an error occurs in the manufacturing process of the display device 1000 (e.g., an error occurs when manufacturing the second opening 455 at the second red pixel R2), a change in luminous efficiency can be prevented. Therefore, if the size of the second opening 455 at the second red pixel R2 is manufactured to be larger than the designed size, the following configuration is made to maintain a constant or substantially constant luminous efficiency of the display device 1000: the first spacing distance S1 and the third spacing distance S3 are designed to be smaller than the preferred spacing distance and the second spacing distance S2 and the fourth spacing distance S4 are designed to be larger than the preferred spacing distance.

[0141] like Figure 10 As shown, the first opening 195 at the first red pixel R1 and the second red pixel R2 of the display device 1000 according to the exemplary embodiment can be patterned as designed, and the second opening 455 at the first red pixel R1 and the second red pixel R2 can be patterned to be offset to the left more than designed.

[0142] In this embodiment, at the first red pixel R1 and the second red pixel R2, the first interval distance S1 and the fourth interval distance S4 are increased, and the second interval distance S2 and the third interval distance S3 are decreased.

[0143] The first spacing distance S1 at the first red pixel R1 is designed to be larger than the preferred spacing distance, so the luminous efficiency decreases as the first spacing distance S1 increases. The second spacing distance S2 at the first red pixel R1 is designed to be smaller than the preferred spacing distance, so the luminous efficiency decreases as the second spacing distance S2 decreases. The third spacing distance S3 at the first red pixel R1 is designed to be larger than the preferred spacing distance, so the luminous efficiency increases as the third spacing distance S3 decreases. The fourth spacing distance S4 at the first red pixel R1 is designed to be smaller than the preferred spacing distance, so the luminous efficiency increases as the fourth spacing distance S4 increases. In one or more embodiments, the decrease in luminous efficiency due to the change in the first spacing distance S1 and the second spacing distance S2 is substantially equal to the increase in luminous efficiency due to the change in the third spacing distance S3 and the fourth spacing distance S4, thereby compensating for the change in luminous efficiency (e.g., causing the change in luminous efficiency to cancel each other out). That is, even if an error occurs in the manufacturing process of the display device 1000 (e.g., an error occurs when manufacturing the second opening 455 at the first red pixel R1), it is possible to prevent changes in luminous efficiency. Therefore, if the position of the second opening 455 at the first red pixel R1 is offset to the left more than designed, the following configuration is made to maintain a constant or substantially constant luminous efficiency of the display device 1000: the first spacing distance S1 and the third spacing distance S3 are designed to be larger than the preferred spacing distance and the second spacing distance S2 and the fourth spacing distance S4 are designed to be smaller than the preferred spacing distance.

[0144] At the second red pixel R2, the first spacing distance S1 is designed to be smaller than the preferred spacing distance, so the luminous efficiency increases as the first spacing distance S1 increases. The second spacing distance S2 at the second red pixel R2 is designed to be larger than the preferred spacing distance, so the luminous efficiency increases as the second spacing distance S2 decreases. The third spacing distance S3 at the second red pixel R2 is designed to be smaller than the preferred spacing distance, so the luminous efficiency decreases as the third spacing distance S3 decreases. The fourth spacing distance S4 at the second red pixel R2 is designed to be larger than the preferred spacing distance, so the luminous efficiency decreases as the fourth spacing distance S4 increases. In one or more embodiments, the increase in luminous efficiency due to the change in the first spacing distance S1 and the second spacing distance S2 is substantially equal to the decrease in luminous efficiency due to the change in the third spacing distance S3 and the fourth spacing distance S4, thereby compensating for the change in luminous efficiency (e.g., causing the changes in luminous efficiency to cancel each other out). That is, even if an error occurs in the manufacturing process of the display device 1000 (e.g., an error occurs when manufacturing the second opening 455 at the second red pixel R2), a change in luminous efficiency can be prevented. Therefore, if the position of the second opening 455 at the second red pixel R2 is offset to the left more than designed, the following configuration is made to maintain a constant or substantially constant luminous efficiency of the display device 1000: the first spacing distance S1 and the third spacing distance S3 are designed to be smaller than the preferred spacing distance and the second spacing distance S2 and the fourth spacing distance S4 are designed to be larger than the preferred spacing distance.

[0145] like Figure 11 As shown, the first opening 195 at the first red pixel R1 and the second red pixel R2 of the display device 1000 according to an exemplary embodiment can be patterned as designed, and the second opening 455 can be patterned to be offset to the right more than designed. In this embodiment, at the first red pixel R1 and the second red pixel R2, the first spacing distance S1 and the fourth spacing distance S4 are decreased, and the second spacing distance S2 and the third spacing distance S3 are increased.

[0146] At the first red pixel R1, the first spacing distance S1 is designed to be larger than the preferred spacing distance, so the luminous efficiency increases as the first spacing distance S1 decreases. The second spacing distance S2 at the first red pixel R1 is designed to be smaller than the preferred spacing distance, so the luminous efficiency increases as the second spacing distance S2 increases. The third spacing distance S3 at the first red pixel R1 is designed to be larger than the preferred spacing distance, so the luminous efficiency decreases as the third spacing distance S3 increases. The fourth spacing distance S4 at the first red pixel R1 is designed to be smaller than the preferred spacing distance, so the luminous efficiency decreases as the fourth spacing distance S4 decreases. In one or more embodiments, the increase in luminous efficiency due to the changes in the first and second spacing distances S1 and S2 is substantially equal to the decrease in luminous efficiency due to the changes in the third and fourth spacing distances S3 and S4, thereby compensating for the changes in luminous efficiency (e.g., causing the changes in luminous efficiency to cancel each other out). That is, even if errors occur in the manufacturing process of the display device 1000 (e.g., errors occur when manufacturing the second opening 455 at the first red pixel R1), changes in luminous efficiency can be prevented. Therefore, if the position of the second opening 455 at the first red pixel R1 is offset to the right more than designed, the following configuration is made to maintain a constant or substantially constant luminous efficiency of the display device 1000: the first spacing distance S1 and the third spacing distance S3 are designed to be larger than the preferred spacing distance and the second spacing distance S2 and the fourth spacing distance S4 are designed to be smaller than the preferred spacing distance.

[0147] At the second red pixel R2, the first spacing distance S1 is designed to be smaller than the preferred spacing distance, so the luminous efficiency decreases as the first spacing distance S1 decreases. The second spacing distance S2 at the second red pixel R2 is designed to be larger than the preferred spacing distance, so the luminous efficiency decreases as the second spacing distance S2 increases. The third spacing distance S3 at the second red pixel R2 is designed to be smaller than the preferred spacing distance, so the luminous efficiency increases as the third spacing distance S3 increases. The fourth spacing distance S4 at the second red pixel R2 is designed to be larger than the preferred spacing distance, so the luminous efficiency increases as the fourth spacing distance S4 decreases. In one or more embodiments, the decrease in luminous efficiency due to the changes in the first and second spacing distances S1 and S2 is substantially equal to the increase in luminous efficiency due to the changes in the third and fourth spacing distances S3 and S4, thereby compensating for the change in luminous efficiency (e.g., causing the changes in luminous efficiency to cancel each other out). That is, even if an error occurs in the manufacturing process of the display device 1000 (e.g., an error occurs when manufacturing the second opening 455 at the second red pixel R2), a change in luminous efficiency can be prevented. Therefore, if the position of the second opening 455 at the second red pixel R2 is offset to the right more than designed, the following configuration will be made to maintain a constant or substantially constant luminous efficiency of the display device 1000: the first spacing distance S1 and the third spacing distance S3 will be designed to be smaller than the preferred spacing distance and the second spacing distance S2 and the fourth spacing distance S4 will be designed to be larger than the preferred spacing distance.

[0148] Return to reference Figure 1 The blue pixel B may include a first blue pixel B1 and a second blue pixel B2. The first opening 195 at the first blue pixel B1 and the second blue pixel B2 may be formed in a substantially square shape. That is, the first side 195a, the second side 195b, the third side 195c, and the fourth side 195d of the first opening 195 at each of the first blue pixels B1 and the second blue pixel B2 may be substantially the same in length. The size of the first opening 195 at the blue pixel B may be larger than the size of the first opening 195 at the red pixel R. Since the brightness of the blue light-emitting element is relatively lower than that of the red light-emitting element, the lower brightness can be compensated by increasing the size of the first opening 195 at the blue pixel B relative to the size of the first opening 195 at the red pixel R. However, this is only an example, and the sizes of the first openings 195 at the blue pixel B and the red pixel R can be varied. For example, the size of the first opening 195 at the blue pixel B may be substantially the same as or smaller than the size of the first opening 195 at the red pixel R.

[0149] The second opening 455 at the first blue pixel B1 and the second blue pixel B2 can be formed in a substantially rectangular shape. The two opposite sides of the second opening 455 can be substantially the same length. The first side 455a and the third side 455c of the second opening 455 can be substantially the same length. The second side 455b and the fourth side 455d of the second opening 455 can be substantially the same length. The size of the second opening 455 at the blue pixel B can be larger than the size of the second opening 455 at the red pixel R. However, the exemplary embodiment is not limited to this, and the sizes of the second openings 455 at the blue pixel B and the red pixel R can be varied.

[0150] The second opening 455 at the first blue pixel B1 and the second opening 455 at the first red pixel R1 can be different in size but similar in shape. Similarly, the second opening 455 at the second blue pixel B2 and the second opening 455 at the second red pixel R2 can be different in size but similar in shape. However, this is merely an example; the second opening 455 at the first blue pixel B1 and the second opening 455 at the first red pixel R1 can be equal in size but different in shape. Alternatively, the second opening 455 at the second blue pixel B2 and the second opening 455 at the second red pixel R2 can be equal in size but have different shapes.

[0151] The first interval distances S1, S2, S3, and S4 at the first blue pixel B1 are substantially equal to the first interval distances S1, S2, S3, and S4 at the first red pixel R1, respectively. Similarly, the first interval distances S1, S2, S3, and S4 at the second blue pixel B2 are substantially equal to the first interval distances S1, S2, S3, and S4 at the second red pixel R2, respectively.

[0152] As previously described, the preferred spacing distances at each of the red pixel R, green pixel G, and blue pixel B can be different from each other. Therefore, the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 at the first blue pixel B1 can be different from the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 at the first red pixel R1, respectively. Furthermore, the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 at the second blue pixel B2 can be different from the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 at the second red pixel R2, respectively.

[0153] The second opening 455 at the first blue pixel B1 can be formed into a rectangular shape extending along the first direction D1, and the second opening 455 at the second blue pixel B2 can be formed into a rectangular shape extending along the second direction D2. Figure 1 Although a first blue pixel B1 and a second blue pixel B2 are shown in the diagram, the display device 1000 may include a plurality of first blue pixels B1 and a plurality of second blue pixels B2. In this embodiment, the number of first blue pixels B1 and the number of second blue pixels B2 may be substantially equal to each other.

[0154] At the first blue pixel B1, the first spacing distance S1 and the third spacing distance S3 can be larger than the preferred spacing distance. At the first blue pixel B1, the second spacing distance S2 and the fourth spacing distance S4 can be smaller than the preferred spacing distance. Furthermore, at the second blue pixel B2, the first spacing distance S1 and the third spacing distance S3 can be smaller than the preferred spacing distance. At the second blue pixel B2, the second spacing distance S2 and the fourth spacing distance S4 can be larger than the preferred spacing distance.

[0155] At the first blue pixel B1 and the second blue pixel B2, the difference between each of the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 and the preferred spacing distance (e.g., 1.3 μm) can be about 0.1 μm or greater and less than about 1.0 μm. That is, at least one of the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 can be about 1.4 μm or greater and less than about 2.3 μm, and the other spacing distances of the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 can be about 0.3 μm or greater and less than about 1.2 μm. Therefore, at the first blue pixel B1 and the second blue pixel B2, the difference between the first spacing distance S1 and the second spacing distance S2 can be about 0.2 μm or greater and less than about 2.0 μm. At the first blue pixel B1 and the second blue pixel B2, the difference between the first spacing distance S1 and the fourth spacing distance S4 can be approximately 0.2 μm or greater and less than approximately 2.0 μm. At the first blue pixel B1 and the second blue pixel B2, the difference between the third spacing distance S3 and the second spacing distance S2 can be approximately 0.2 μm or greater and less than approximately 2.0 μm. At the first blue pixel B1 and the second blue pixel B2, the difference between the third spacing distance S3 and the fourth spacing distance S4 can be approximately 0.2 μm or greater and less than approximately 2.0 μm.

[0156] Therefore, by designing different spacing distances S1-S4 at a single pixel PX, even if process errors occur during the manufacturing of the display device 1000, changes in luminous efficiency can be prevented or at least reduced. The principle by which this compensates for changes in luminous efficiency in the blue pixel B is essentially the same as the principle of the red pixel R described above.

[0157] In the display device 1000 according to an exemplary embodiment, it has been described that the first opening 195 at the red pixel R and the blue pixel B is formed in a square shape, the first spacing distance S1 and the third spacing distance S3 are equal to each other, the second spacing distance S2 and the fourth spacing distance S4 are equal to each other, and the first spacing distance S1 and the second spacing distance S2 are different from each other at the red pixel R and the blue pixel B. The design of the red pixel R and the blue pixel B is not limited to this; the first spacing distance S1 and the second spacing distance S2 may be equal to each other, the third spacing distance S3 and the fourth spacing distance S4 may be equal to each other, and the first spacing distance S1 and the third spacing distance S3 may be different from each other. In this embodiment, when an error occurs in the manufacturing process of the display device 1000, a change in luminous efficiency will occur. For example, when an upward offset or a downward offset occurs, fluctuations in luminous efficiency will occur. However, when a leftward or rightward offset occurs, fluctuations in luminous efficiency can be prevented.

[0158] Green pixel G may include a first green pixel G1, a second green pixel G2, a third green pixel G3, and a fourth green pixel G4. The first opening 195 at the first green pixel G1, the second green pixel G2, the third green pixel G3, and the fourth green pixel G4 may be formed in an approximately rectangular shape. That is, at the first green pixel G1, the second green pixel G2, the third green pixel G3, and the fourth green pixel G4, the two facing sides of the first opening 195 may be substantially equal in length.

[0159] The first side 195a and the third side 195c of the first opening 195 can be substantially equal in length to each other.

[0160] The second side 195b and the fourth side 195d of the first opening 195 can be substantially equal in length. In the first opening 195 at the first green pixel G1 and the fourth green pixel G4, the first side 195a and the third side 195c can be longer than the second side 195b and the fourth side 195d. In the first opening 195 at the second green pixel G2 and the third green pixel G3, the first side 195a and the third side 195c can be shorter than the second side 195b and the fourth side 195d.

[0161] As previously described, the size of the first opening 195 at the blue pixel B can be relatively larger than the size of the first opening 195 at the red pixel R. In this embodiment, the green pixel G can be formed in a rectangular shape so that the spacing between the first openings 195 at each pixel PX is constant. That is, the side of the green pixel G adjacent to the blue pixel B can be relatively long, and the side of the green pixel G adjacent to the red pixel R can be relatively short.

[0162] The second openings 455 at the first green pixel G1, the second green pixel G2, the third green pixel G3, and the fourth green pixel G4 can be rectangular. In the second openings 455 at the first green pixel G1, the second green pixel G2, the third green pixel G3, and the fourth green pixel G4, two opposite sides can be substantially equal in length. In the second opening 455, the first side 455a and the third side 455c can be substantially equal in length. In the second opening 455, the second side 455b and the fourth side 455d can be substantially equal in length. In the second openings 455 at the first green pixel G1 and the fourth green pixel G4, the first side 455a and the third side 455c can be longer than the second side 455b and the fourth side 455d. In the second openings 455 at the second green pixel G2 and the third green pixel G3, the first side 455a and the third side 455c can be shorter than the second side 455b and the fourth side 455d.

[0163] At the first green pixel G1 and the third green pixel G3, the first spacing distance S1 and the second spacing distance S2 can be different from the third spacing distance S3 and the fourth spacing distance S4. At the first green pixel G1 and the third green pixel G3, the first spacing distance S1 can be substantially equal to the second spacing distance S2, and the third spacing distance S3 can be substantially equal to the fourth spacing distance S4. At the first green pixel G1 and the third green pixel G3, the first spacing distance S1 can be smaller than the third spacing distance S3, and the first spacing distance S1 can be smaller than the fourth spacing distance S4. At the first green pixel G1 and the third green pixel G3, the second spacing distance S2 can be smaller than the third spacing distance S3, and the second spacing distance S2 can be smaller than the fourth spacing distance S4.

[0164] At the second green pixel G2 and the fourth green pixel G4, the first spacing distance S1 and the second spacing distance S2 can be different from the third spacing distance S3 and the fourth spacing distance S4. At the second green pixel G2 and the fourth green pixel G4, the first spacing distance S1 can be substantially equal to the second spacing distance S2, and the third spacing distance S3 can be substantially equal to the fourth spacing distance S4. At the second green pixel G2 and the fourth green pixel G4, the first spacing distance S1 can be larger than the third spacing distance S3, and the second spacing distance S2 can be larger than the fourth spacing distance S4. At the second green pixel G2 and the fourth green pixel G4, the second spacing distance S2 can be larger than the third spacing distance S3, and the second spacing distance S2 can be larger than the fourth spacing distance S4.

[0165] At the first green pixel G1 and the third green pixel G3, the first spacing distance S1 and the second spacing distance S2 can be substantially equal to the second spacing distance S2 and the fourth spacing distance S4 at the first red pixel R1. Similarly, the third spacing distance S3 and the fourth spacing distance S4 at the first green pixel G1 and the third green pixel G3 can be substantially equal to the first spacing distance S1 and the third spacing distance S3 at the first red pixel R1. Likewise, the first spacing distance S1 and the second spacing distance S2 at the second green pixel G2 and the fourth green pixel G4 can be substantially equal to the first spacing distance S1 and the third spacing distance S3 at the first red pixel R1.

[0166] As previously described, the preferred spacing distances at the red pixel R, green pixel G, and blue pixel B can be different from each other. Therefore, the first spacing distance S1 and the second spacing distance S2 at the first green pixel G1 and the third green pixel G3 can be different from the second spacing distance S2 and the fourth spacing distance S4 at the first red pixel R1. Furthermore, the third spacing distance S3 and the fourth spacing distance S4 at the first green pixel G1 and the third green pixel G3 can be different from the first spacing distance S1 and the third spacing distance S3 at the first red pixel R1. Similarly, the first spacing distance S1 and the second spacing distance S2 at the second green pixel G2 and the fourth green pixel G4 can be different from the first spacing distance S1 and the third spacing distance S3 at the first red pixel R1. Furthermore, the third spacing distance S3 and the fourth spacing distance S4 at the second green pixel G2 and the fourth green pixel G4 can be different from the second spacing distance S2 and the fourth spacing distance S4 at the first red pixel R1.

[0167] The first opening 195 and the second opening 455 at the first green pixel G1 and the fourth green pixel G4 can be formed into a rectangular shape extending along the second direction D2. The first opening 195 and the second opening 455 at the second green pixel G2 and the third green pixel G3 can be formed into a rectangular shape extending along the first direction D1. The first opening 195 at the first green pixel G1 and the third green pixel G3 is relatively close to the first side 455a and the second side 455b of the second opening 455. The first opening 195 at the second green pixel G2 and the fourth green pixel G4 is relatively close to the third side 455c and the fourth side 455d of the second opening 455. Figure 1 The diagram shows a first green pixel G1, a second green pixel G2, a third green pixel G3, and a fourth green pixel G4. However, the display device 1000 may include multiple first green pixels G1, multiple second green pixels G2, multiple third green pixels G3, and multiple fourth green pixels G4. In this embodiment, the number of first green pixels G1, the number of second green pixels G2, the number of third green pixels G3, and the number of fourth green pixels G4 may be substantially equal to each other.

[0168] At the first green pixel G1 and the third green pixel G3, the first spacing distance S1 and the second spacing distance S2 can be smaller than the preferred spacing distance. At the first green pixel G1 and the third green pixel G3, the third spacing distance S3 and the fourth spacing distance S4 can be larger than the preferred spacing distance. At the second green pixel G2 and the fourth green pixel G4, the first spacing distance S1 and the second spacing distance S2 can be larger than the preferred spacing distance. At the second green pixel G2 and the fourth green pixel G4, the third spacing distance S3 and the fourth spacing distance S4 can be smaller than the preferred spacing distance.

[0169] At the first green pixel G1, the second green pixel G2, the third green pixel G3, and the fourth green pixel G4, the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 can each differ from the preferred spacing distance (e.g., 1.3 μm) by approximately 0.1 μm or more and less than approximately 1.0 μm. That is, one of the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 can be approximately 1.4 μm or more and less than approximately 2.3 μm, and the other spacing distances among the first spacing distance S1, the second spacing distance S2, the third spacing distance S3, and the fourth spacing distance S4 can be approximately 0.3 μm or more and less than approximately 1.2 μm. Therefore, at the first green pixel G1, the second green pixel G2, the third green pixel G3, and the fourth green pixel G4, the difference between the first spacing distance S1 and the third spacing distance S3 can be approximately 0.2 μm or more and less than approximately 2.0 μm. At the first green pixel G1, the second green pixel G2, the third green pixel G3, and the fourth green pixel G4, the difference between the first spacing distance S1 and the fourth spacing distance S4 can be approximately 0.2 μm or greater and less than approximately 2.0 μm. At the first green pixel G1, the second green pixel G2, the third green pixel G3, and the fourth green pixel G4, the difference between the second spacing distance S2 and the third spacing distance S3 can be approximately 0.2 μm or greater and less than approximately 2.0 μm. At the first green pixel G1, the second green pixel G2, the third green pixel G3, and the fourth green pixel G4, the difference between the second spacing distance S2 and the fourth spacing distance S4 can be approximately 0.2 μm or greater and less than approximately 2.0 μm.

[0170] As described in more detail below, in the display device 1000 according to an exemplary embodiment, the spacing S at a pixel PX is designed to be different, thereby preventing changes in luminous efficiency even when errors occur in the manufacturing process of the display device 1000. Referring below... Figures 12 to 15 The principle of compensating for changes in luminous efficiency when errors occur in the manufacturing process of the display device 1000 will be described.

[0171] Figure 12 This illustrates the change in luminous efficiency in some layers of a display device according to an exemplary embodiment, where the layers are patterned to be smaller than designed. Figure 13 The diagram illustrates the change in luminous efficiency when some layers are patterned larger than designed in a display device according to an exemplary embodiment. Figure 14 The diagram illustrates the change in luminous efficiency in a display device according to an exemplary embodiment when some layers are offset to the left more than designed. Figure 15 This illustrates the change in luminous efficiency in a display device according to an exemplary embodiment when some layers are offset to the right more than designed. Figures 12-15In the diagram, solid arrows indicate an increase in luminous efficiency, while dashed arrows indicate a decrease in luminous efficiency.

[0172] like Figure 12 As shown, at the first green pixel G1, second green pixel G2, third green pixel G3, and fourth green pixel G4 of the display device 1000 according to an exemplary embodiment, the first opening 195 can be patterned as designed, and the second opening 455 can be patterned to be smaller than designed. In this embodiment, at the first green pixel G1, second green pixel G2, third green pixel G3, and fourth green pixel G4, the first spacing distance S1, second spacing distance S2, third spacing distance S3, and fourth spacing distance S4 are reduced.

[0173] The first spacing distance S1 is designed to be smaller than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, therefore the luminous efficiency decreases as the first spacing distance S1 decreases. The second spacing distance S2 is designed to be smaller than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, therefore the luminous efficiency decreases as the second spacing distance S2 decreases. The third spacing distance S3 is designed to be larger than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, therefore the luminous efficiency increases as the third spacing distance S3 decreases. The fourth spacing distance S4 is designed to be larger than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, therefore the luminous efficiency increases as the fourth spacing distance S4 decreases. In one or more embodiments, the decrease in luminous efficiency due to the decrease in the first spacing distance S1 and the second spacing distance S2 is substantially equal to the increase in luminous efficiency due to the decrease in the third spacing distance S3 and the fourth spacing distance S4, thereby compensating for the change in luminous efficiency (e.g., causing the changes in luminous efficiency to cancel each other out). That is, even if errors occur in the manufacturing process of the display device 1000 (for example, errors occur when manufacturing the second opening 455 at the first green pixel G1 and the third green pixel G3), changes in luminous efficiency can be prevented. Therefore, if the size of the second opening 455 at the first green pixel G1 and the third green pixel G3 is smaller than designed, the display device 1000 is configured to maintain a constant or substantially constant luminous efficiency by designing the first spacing distance S1 and the second spacing distance S2 at the first green pixel G1 and the third green pixel G3 to be smaller than the preferred spacing distance, and designing the third spacing distance S3 and the fourth spacing distance S4 at the first green pixel G1 and the third green pixel G3 to be larger than the preferred spacing distance.

[0174] The first spacing distance S1 is designed to be larger than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, so the luminous efficiency increases as the first spacing distance S1 decreases. The second spacing distance S2 is designed to be larger than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, so the luminous efficiency increases as the second spacing distance S2 decreases. The third spacing distance S3 is designed to be smaller than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, so the luminous efficiency decreases as the third spacing distance S3 decreases. The fourth spacing distance S4 is designed to be smaller than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, so the luminous efficiency decreases as the fourth spacing distance S4 decreases. In one or more embodiments, the increase in luminous efficiency due to the decrease in the first spacing distance S1 and the second spacing distance S2 is substantially equal to the decrease in luminous efficiency due to the decrease in the third spacing distance S3 and the fourth spacing distance S4, thereby compensating for the change in luminous efficiency (e.g., causing the changes in luminous efficiency to cancel each other out). That is, even if errors occur in the manufacturing process of the display device 1000 (for example, errors occur when manufacturing the second opening 455 at the second green pixel G2 and the fourth green pixel G4), changes in luminous efficiency can be prevented. Therefore, if the size of the second opening 455 at the second green pixel G2 and the fourth green pixel G4 is smaller than designed, the display device 1000 is configured to maintain a constant or substantially constant luminous efficiency by designing the first spacing distance S1 and the second spacing distance S2 at the second green pixel G2 and the fourth green pixel G4 to be larger than the preferred spacing distance and the third spacing distance S3 and the fourth spacing distance S4 at the second green pixel G2 and the fourth green pixel G4 to be smaller than the preferred spacing distance.

[0175] like Figure 13 As shown, at the first green pixel G1, second green pixel G2, third green pixel G3, and fourth green pixel G4 of the display device 1000 according to an exemplary embodiment, the first opening 195 can be patterned as designed, and the second opening 455 can be patterned to be larger than designed. In this embodiment, at the first green pixel G1, second green pixel G2, third green pixel G3, and fourth green pixel G4, the first spacing distance S1, second spacing distance S2, third spacing distance S3, and fourth spacing distance S4 are increased.

[0176] The first spacing distance S1 is designed to be smaller than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, so the luminous efficiency increases as the first spacing distance S1 increases. The second spacing distance S2 is designed to be smaller than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, so the luminous efficiency increases as the second spacing distance S2 increases. The third spacing distance S3 is designed to be larger than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, so the luminous efficiency decreases as the third spacing distance S3 increases. The fourth spacing distance S4 is designed to be larger than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, so the luminous efficiency decreases as the fourth spacing distance S4 increases. In one or more embodiments, the increase in luminous efficiency due to the increase of the first spacing distance S1 and the second spacing distance S2 is substantially equal to the decrease in luminous efficiency due to the increase of the third spacing distance S3 and the fourth spacing distance S4, thereby compensating for the change in luminous efficiency (e.g., causing the changes in luminous efficiency to cancel each other out). That is, even if errors occur in the manufacturing process of the display device 1000 (for example, errors occur when manufacturing the second opening 455 at the first green pixel G1 and the third green pixel G3), changes in luminous efficiency can be prevented. Therefore, if the size of the second opening 455 at the first green pixel G1 and the third green pixel G3 is larger than designed, the display device 1000 is configured to maintain a constant or substantially constant luminous efficiency by designing the first spacing distance S1 and the second spacing distance S2 at the first green pixel G1 and the third green pixel G3 to be smaller than the preferred spacing distance and the third spacing distance S3 and the fourth spacing distance S4 at the first green pixel G1 and the third green pixel G3 to be larger than the preferred spacing distance.

[0177] The first spacing distance S1 is designed to be larger than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, therefore the luminous efficiency decreases as the first spacing distance S1 increases. The second spacing distance S2 is designed to be larger than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, therefore the luminous efficiency decreases as the second spacing distance S2 increases. The third spacing distance S3 is designed to be smaller than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, therefore the luminous efficiency increases as the third spacing distance S3 increases. The fourth spacing distance S4 is designed to be smaller than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, therefore the luminous efficiency increases as the fourth spacing distance S4 increases. In one or more embodiments, the decrease in luminous efficiency due to the increase of the first spacing distance S1 and the second spacing distance S2 is substantially equal to the increase in luminous efficiency due to the increase of the third spacing distance S3 and the fourth spacing distance S4, thereby compensating for the change in luminous efficiency (e.g., causing the changes in luminous efficiency to cancel each other out). That is, even if errors occur in the manufacturing process of the display device 1000 (for example, errors occur when manufacturing the second opening 455 at the second green pixel G2 and the fourth green pixel G4), changes in luminous efficiency can be prevented. Therefore, if the size of the second opening 455 at the second green pixel G2 and the fourth green pixel G4 is larger than designed, the display device 1000 is configured to maintain a constant or substantially constant luminous efficiency by designing the first spacing distance S1 and the second spacing distance S2 at the second green pixel G2 and the fourth green pixel G4 to be larger than the preferred spacing distance and the third spacing distance S3 and the fourth spacing distance S4 at the second green pixel G2 and the fourth green pixel G4 to be smaller than the preferred spacing distance.

[0178] like Figure 14 As shown, at the first green pixel G1, second green pixel G2, third green pixel G3, and fourth green pixel G4 of the display device 1000 according to an exemplary embodiment, the first opening 195 can be patterned as designed, and the second opening 455 can be patterned to be offset to the left more than designed. In this embodiment, at the first green pixel G1, second green pixel G2, third green pixel G3, and fourth green pixel G4, the first spacing distance S1 and the fourth spacing distance S4 are increased, and the second spacing distance S2 and the third spacing distance S3 are decreased.

[0179] The first spacing distance S1 is designed to be smaller than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, therefore the luminous efficiency increases as the first spacing distance S1 increases. The second spacing distance S2 is designed to be smaller than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, therefore the luminous efficiency decreases as the second spacing distance S2 decreases. The third spacing distance S3 is designed to be larger than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, therefore the luminous efficiency increases as the third spacing distance S3 decreases. The fourth spacing distance S4 is designed to be larger than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, therefore the luminous efficiency decreases as the fourth spacing distance S4 increases.

[0180] Only at the first green pixel G1, the increase in luminous efficiency due to changes in the first spacing distance S1 and the third spacing distance S3 is greater than the decrease in luminous efficiency due to changes in the second spacing distance S2 and the fourth spacing distance S4. Only at the third green pixel G3, the increase in luminous efficiency due to changes in the first spacing distance S1 and the third spacing distance S3 is smaller than the decrease in luminous efficiency due to changes in the second spacing distance S2 and the fourth spacing distance S4. In one or more embodiments, the difference between the increase and decrease in luminous efficiency at the first green pixel G1 and the difference between the increase and decrease in luminous efficiency at the third green pixel G3 are substantially equal, thereby compensating for changes in luminous efficiency (e.g., the change in luminous efficiency at the first green pixel G1 is offset by the change in luminous efficiency at the third green pixel G3). The number of first green pixels G1 and the number of third green pixels G3 are substantially equal to each other, so even if errors occur in the manufacturing process of the display device 1000, changes in luminous efficiency can be prevented. Therefore, if the second opening 455 is positioned further to the left at the first green pixel G1 and the third green pixel G3 than designed, the following configuration is made to maintain a constant or substantially constant luminous efficiency of the display device 1000: the first spacing distance S1 and the second spacing distance S2 at the first green pixel G1 and the third green pixel G3 are designed to be smaller than the preferred spacing distance, and the third spacing distance S3 and the fourth spacing distance S4 at the first green pixel G1 and the third green pixel G3 are designed to be larger than the preferred spacing distance.

[0181] The first spacing distance S1 is designed to be larger than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, therefore the luminous efficiency decreases as the first spacing distance S1 increases. The second spacing distance S2 is designed to be larger than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, therefore the luminous efficiency increases as the second spacing distance S2 decreases. The third spacing distance S3 is designed to be smaller than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, therefore the luminous efficiency decreases as the third spacing distance S3 decreases. The fourth spacing distance S4 is designed to be smaller than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, therefore the luminous efficiency increases as the fourth spacing distance S4 increases.

[0182] Only at the second green pixel G2, the decrease in luminous efficiency due to changes in the first spacing distance S1 and the third spacing distance S3 is smaller than the increase in luminous efficiency due to changes in the second spacing distance S2 and the fourth spacing distance S4. Only at the fourth green pixel G4, the decrease in luminous efficiency due to changes in the first spacing distance S1 and the third spacing distance S3 is larger than the increase in luminous efficiency due to changes in the second spacing distance S2 and the fourth spacing distance S4. In one or more embodiments, the difference between the increase and decrease in luminous efficiency at the second green pixel G2 is substantially equal to the difference between the increase and decrease in luminous efficiency at the fourth green pixel G4, thereby compensating for changes in luminous efficiency (e.g., the change in luminous efficiency at the second green pixel G2 is offset by the change in luminous efficiency at the fourth green pixel G4). The number of second green pixels G2 and the number of fourth green pixels G4 are substantially equal to each other, thus preventing changes in luminous efficiency even if errors occur in the process. Therefore, if the position of the second opening 455 at the second green pixel G2 and the fourth green pixel G4 is offset to the left more than designed, the following configuration is made to maintain a constant or substantially constant luminous efficiency of the display device 1000: the first spacing distance S1 and the second spacing distance S2 at the second green pixel G2 and the fourth green pixel G4 are designed to be larger than the preferred spacing distance, and the third spacing distance S3 and the fourth spacing distance S4 at the second green pixel G2 and the fourth green pixel G4 are designed to be smaller than the preferred spacing distance.

[0183] like Figure 15As shown, at the first green pixel G1, second green pixel G2, third green pixel G3, and fourth green pixel G4 of the display device 1000 according to an exemplary embodiment, the first opening 195 can be patterned as designed, and the second opening 455 can be patterned to be offset to the right more than designed. In this case, at the first green pixel G1, second green pixel G2, third green pixel G3, and fourth green pixel G4, the first spacing distance S1 and the fourth spacing distance S4 decrease, and the second spacing distance S2 and the third spacing distance S3 increase.

[0184] The first spacing distance S1 is designed to be smaller than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, therefore the luminous efficiency decreases as the first spacing distance S1 decreases. The second spacing distance S2 is designed to be smaller than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, therefore the luminous efficiency increases as the second spacing distance S2 increases. The third spacing distance S3 is designed to be larger than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, therefore the luminous efficiency decreases as the third spacing distance S3 increases. The fourth spacing distance S4 is designed to be larger than the preferred spacing distance at the first green pixel G1 and the third green pixel G3, therefore the luminous efficiency increases as the fourth spacing distance S4 decreases.

[0185] Only at the first green pixel G1, the decrease in luminous efficiency due to changes in the first spacing distance S1 and the third spacing distance S3 is greater than the increase in luminous efficiency due to changes in the second spacing distance S2 and the fourth spacing distance S4. Only at the third green pixel G3, the decrease in luminous efficiency due to changes in the first spacing distance S1 and the third spacing distance S3 is smaller than the increase in luminous efficiency due to changes in the second spacing distance S2 and the fourth spacing distance S4. In one or more embodiments, the difference between the decrease and increase in luminous efficiency at the first green pixel G1 and the difference between the decrease and increase in luminous efficiency at the third green pixel G3 are substantially equal to each other, thereby compensating for changes in luminous efficiency (e.g., the change in luminous efficiency at the first green pixel G1 is offset by the change in luminous efficiency at the third green pixel G3). The number of first green pixels G1 and the number of third green pixels G3 are substantially the same, so even if errors occur in the process, changes in luminous efficiency can be prevented. Therefore, if the position of the second opening 455 at the first green pixel G1 and the third green pixel G3 is offset to the right more than designed, the following configuration is made to maintain a constant or substantially constant luminous efficiency of the display device 1000: the first spacing distance S1 and the second spacing distance S2 at the first green pixel G1 and the third green pixel G3 are designed to be smaller than the preferred spacing distance, and the third spacing distance S3 and the fourth spacing distance S4 at the first green pixel G1 and the third green pixel G3 are designed to be larger than the preferred spacing distance.

[0186] The first spacing distance S1 is designed to be larger than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, therefore the luminous efficiency increases as the first spacing distance S1 decreases. The second spacing distance S2 is designed to be larger than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, therefore the luminous efficiency decreases as the second spacing distance S2 increases. The third spacing distance S3 is designed to be smaller than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, therefore the luminous efficiency increases as the third spacing distance S3 increases. The fourth spacing distance S4 is designed to be smaller than the preferred spacing distance at the second green pixel G2 and the fourth green pixel G4, therefore the luminous efficiency decreases as the fourth spacing distance S4 decreases.

[0187] Only at the second green pixel G2, the increase in luminous efficiency due to changes in the first spacing distance S1 and the third spacing distance S3 is smaller than the decrease in luminous efficiency due to changes in the second spacing distance S2 and the fourth spacing distance S4. Only at the fourth green pixel G4, the increase in luminous efficiency due to changes in the first spacing distance S1 and the third spacing distance S3 is larger than the decrease in luminous efficiency due to changes in the second spacing distance S2 and the fourth spacing distance S4. In one or more embodiments, the difference between the increase and decrease in luminous efficiency at the second green pixel G2 is substantially equal to the difference between the increase and decrease in luminous efficiency at the fourth green pixel G4, thereby compensating for changes in luminous efficiency (e.g., the change in luminous efficiency at the second green pixel G2 is offset by the change in luminous efficiency at the fourth green pixel G4). The number of second green pixels G2 and the number of fourth green pixels G4 are substantially equal to each other, thus preventing changes in luminous efficiency even if errors occur in the process. Therefore, if the position of the second opening 455 at the second green pixel G2 and the fourth green pixel G4 is offset to the right more than designed, the following configuration is made to maintain a constant or substantially constant luminous efficiency of the display device 1000: the first spacing distance S1 and the second spacing distance S2 at the second green pixel G2 and the fourth green pixel G4 are designed to be larger than the preferred spacing distance, and the third spacing distance S3 and the fourth spacing distance S4 at the second green pixel G2 and the fourth green pixel G4 are designed to be smaller than the preferred spacing distance.

[0188] In the display device 1000 according to an exemplary embodiment, the first opening 195 at the green pixel G is formed in a rectangular shape. The first spacing distance S1 and the second spacing distance S2 are equal to each other, and the third spacing distance S3 and the fourth spacing distance S4 are equal to each other. The first spacing distance S1 and the third spacing distance S3 at the green pixel G are different from each other. However, the design of the green pixel G is not limited to this; the first spacing distance S1 and the second spacing distance S2 may be different from each other, the first spacing distance S1 and the third spacing distance S3 may be equal to each other, and the second spacing distance S2 and the fourth spacing distance S4 may be equal to each other. In this embodiment, when errors occur in the manufacturing process of the display device 1000, the increase in luminous efficiency in some areas and the decrease in luminous efficiency in other areas may be different from each other, resulting in a change in the overall luminous efficiency of the display device 1000. However, even in this embodiment, compared to embodiments where the first spacing distance S1 to the fourth spacing distance S4 are equal to each other, the change in the luminous efficiency of the display device 1000 can be reduced.

[0189] Next, refer to Figure 16 and Figure 17 The following describes a display device 1000 according to an exemplary embodiment.

[0197] Green pixel G may include a first green pixel G1, a second green pixel G2, a third green pixel G3, and a fourth green pixel G4. The first opening 195 at the first green pixel G1, second green pixel G2, third green pixel G3, and fourth green pixel G4 may be formed in an approximately octagonal shape. In this embodiment, in the first opening 195 at the first green pixel G1, second green pixel G2, third green pixel G3, and fourth green pixel G4, two opposite sides may have substantially the same length. The first side 195a and the fifth side 195e of the first opening 195 may have substantially the same length.
