[0042] Figure 15A and Figure 15B It is along Figure 11 A schematic cross-sectional view of the display device taken by line B-B'. Detailed Implementation

[0043] Reference will now be made in detail to embodiments illustrated in the accompanying drawings, in which the same reference numerals refer to the same elements throughout. In this respect, the present embodiments may take different forms and should not be construed as limited to the description set forth herein. Accordingly, embodiments are described below only with reference to the accompanying drawings to illustrate aspects of the present description.

[0044] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, “a,” “the,” and “at least one” do not indicate a limitation of quantity and are intended to include both the singular and the plural unless the context clearly indicates otherwise. Thus, reference to an element “a” followed by reference to an element in a claim includes one such element and a plurality of such elements. For example, “element” has the same meaning as “at least one element” unless the context clearly indicates otherwise. “At least one” is not to be construed as limited to “a.” “Or” means “and / or.” As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. Throughout this disclosure, the expression “at least one of a, b, and c” means only a, only b, only c, both a and b, both a and c, both b and c, all of a, b, and c, or variations thereof.

[0045] Because this disclosure allows for various modifications and numerous embodiments, the embodiments will be illustrated in the accompanying drawings and described in a detailed description. The effects and features of this disclosure and its implementation methods will be elucidated with reference to the embodiments described in detail below with reference to the accompanying drawings. However, this disclosure is not limited to the embodiments described below and can be implemented in various forms.

[0046] In the following description, embodiments will be referenced to the accompanying drawings, wherein, when described with reference to the drawings, the same or corresponding elements are given the same reference numerals, and repeated descriptions thereof are omitted. Within the drawings and text of this disclosure, reference numerals indicating elements in the singular form may also be used to refer to multiple elements.

[0047] In the following embodiments, terms such as “first” and “second” are not used in a limiting sense, but rather for the purpose of distinguishing one element from another.

[0048] In the following embodiments, unless the context explicitly indicates otherwise, singular expressions include plural expressions.

[0049] It will be understood that the terms “comprising” or “including” as used herein indicate the presence of a stated feature or component, but do not preclude the addition of one or more other features or components.

[0050] In the following embodiments, when a layer, region, or element is referred to as being "on" another part or related to another part, this can include not only cases where the layer, region, or element is directly on the other part, but also cases where an intermediary layer, region, or element is disposed between the layer, region, or element and the other part. Conversely, when a layer, region, or element is referred to as being "directly" on another part or related to another part, no intermediary layer, region, or element is disposed therein. For example, elements that are directly on or in contact with each other may (physically) form an interface therebetween.

[0051] For ease of explanation, the dimensions of the elements in the accompanying drawings may be exaggerated or reduced. By way of example, the dimensions and thicknesses of each element shown in the drawings are arbitrarily represented for ease of description, and therefore, this disclosure is not necessarily limited thereto.

[0052] In the following embodiments, the x-axis, y-axis, and z-axis directions are not limited to directions corresponding to the three axes of a Cartesian coordinate system, and can be interpreted in a general sense that includes them. For example, the x-axis, y-axis, and z-axis directions can be perpendicular to each other, or they can represent different directions that are not perpendicular to each other.

[0053] Furthermore, relative terms such as “down” or “bottom” and “up” or “top” may be used herein to describe the relationship between one element and another as shown in the accompanying drawings. It will be understood that, in addition to the orientations depicted in the drawings, the relative terms are intended to also cover different orientations of the device. For example, if a device in one of the drawings is flipped, an element described as being “down” of the other elements will be oriented “up” of the other elements. Thus, depending on the specific orientation of the drawing, the term “down” can encompass both “down” and “up” orientations. Similarly, if a device in one of the drawings is flipped, an element described as being “below” or “under” the other elements will be oriented “above” the other elements. Thus, the terms “below” or “under” can encompass both “up” and “down” orientations.

[0054] Where embodiments may be implemented differently, a particular process sequence may be performed in a different order than that described. As an example, two processes described consecutively may be performed substantially simultaneously, or may be performed in the reverse order described.

[0055] Given the measurements discussed and the errors associated with the measured values ​​of a particular quantity (i.e., limitations of the measurement system), the terms “about” or “approximately” as used herein include stated values ​​and refer to a range of acceptable deviations from that particular value as determined by one of ordinary skill in the art. For example, “about” may mean within one or more standard deviations, or within ±30%, ±20%, ±10%, or ±5% of the stated value.

[0056] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It will also be understood that terms such as those defined in common dictionaries shall be interpreted as having the same meaning as they have in the relevant art and in the context of this disclosure, and shall not be interpreted in an idealized or overly formal sense, unless expressly so defined herein.

[0057] The embodiments described herein are illustrated with reference to schematic cross-sectional views of preferred embodiments. Therefore, variations in the illustrated shapes will be expected due to factors such as manufacturing techniques and / or tolerances. Consequently, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but rather include deviations in shape, for example, resulting from manufacturing processes. For instance, regions shown or described as flat may generally have rough and / or non-linear characteristics. Furthermore, sharp corners shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to illustrate the precise shapes of the regions, nor are they intended to limit the scope of the present claims.

Furthermore, where the display module 2 has the function of transmitting light, the display module 2 can be applied to electronic devices 1 such as smart windows or transparent display devices that display the background and the displayed image together. The types of electronic devices 1 according to the embodiment are not limited to this example, and various other electronic devices not shown as examples can be applied.

[0077] For ease of description, the following text will primarily focus on the case where electronic device 1 is a smartphone.

[0078] Figure 5 This is a schematic perspective view of electronic device 1 according to an embodiment. Figure 6 yes Figure 5 A schematic exploded perspective view of the electronic device 1 shown in the figure.

[0079] refer to Figure 5 and Figure 6 The electronic device 1 may include a display device DV comprising a cover window 70, a display panel 10, a data driver 20 and a display circuit board 30 as a first circuit board, a component 40, a bracket 60 as an intermediate cover, a main circuit board 50 as a second circuit board, a battery 80 and / or a lower cover 90.

[0080] In the plan view of this specification, "left," "right," "up," and "down" indicate the directions when the display panel 10 is viewed in a direction perpendicular to (e.g., orthogonal to the main surface of the display panel 10). As an example, "left" represents the -x direction, "right" represents the +x direction, "up" represents the +y direction, and "down" represents the -y direction.

[0081] Electronic device 1 can be shown in a plan view as having a generally rectangular shape. For example, as shown... Figure 5 As shown, in the xy-plane, electronic device 1 can have a generally rectangular shape, having a shorter side in the x-axis direction and a longer side in the y-axis direction. The xy-plane can be defined by intersecting x-axis directions (as a first direction) and y-axis directions (as a second direction). The thickness of electronic device 1, display module 2, and its various components or layers can be defined in a direction orthogonal (or perpendicular) to the xy-plane (e.g., along the z-axis direction (as a third direction, such as the thickness direction)).

[0082] In this case, the edge or perimeter where the short side extending in the x-axis direction intersects the long side extending in the y-axis direction can form a right angle, or it can have an arc shape containing a preset curvature. In the planar view, the planar shape of the electronic device 1 is not limited to a rectangle, but can include other polygonal shapes, elliptical shapes, or irregular planar shapes.

[0083] A cover window 70 can be disposed on the display panel 10 to cover the upper surface of the display panel 10. The cover window 70 can protect the upper surface of the display panel 10.

[0084] The cover window 70 may include a transmissive cover portion DA 70 and a light-shielding cover portion NDA 70, wherein the transmissive cover portion DA 70 corresponds to the display panel 10, and the light-shielding cover portion NDA 70 is adjacent to the transmissive cover portion DA 70. In an embodiment, the light-shielding cover portion NDA 70 may surround the transmissive cover portion DA 70, but is not limited thereto. The light-shielding cover portion NDA 70 may include an opaque material (e.g., a colored opaque material) that blocks light. The light-shielding cover portion NDA 70 may include a pattern visible from the outside of the electronic device 1 (e.g., to the user) when no image is displayed.

[0085] Display panel 10 may be disposed below cover window 70. Display panel 10 may overlap with (or face the cover window 70) the transmissive cover portion DA 70 of cover window 70. Display panel 10 may include display area DA. Display area DA may overlap with the transmissive cover portion DA 70 and not with the light-shielding cover portion NDA 70, or may overlap with both the transmissive cover portion DA 70 and the light-shielding cover portion NDA 70. Display area DA is the area (or planar area) for displaying an image. Display area DA may include a region (hereinafter referred to as the component area) located within the entire planar area of ​​display area DA, in which light emitted from component 40 disposed below display panel 10 is transmitted into display panel 10, transmitted through display panel 10, and / or transmitted from display panel 10.

[0086] Component 40, as a functional component, may include sensors and cameras that use visible light, infrared light, and sound to provide functionality to electronic device 1.

[0087] Display panel 10 can be a light-emitting display panel that includes light-emitting diodes (LEDs) as display elements. The LEDs can include organic light-emitting diodes (OLEDs) containing organic materials or inorganic light-emitting diodes (LEDs) containing inorganic materials. Inorganic LEDs can include PN junction diodes containing inorganic semiconductor materials. When a forward voltage is applied to the PN junction diode, holes and electrons are injected, and light of a preset color can be emitted while the energy generated by the recombination of holes and electrons is converted into light energy. Inorganic LEDs can have widths ranging from a few micrometers to several hundred micrometers. Inorganic LEDs can be represented by miniature LEDs.

[0088] The display panel 10 can be a rigid display panel that is rigid and therefore not easily bent, folded, or rolled up, or a flexible display panel that is flexible and therefore easily bent, folded, or rolled up. As an example, the display panel 10 may include a foldable display panel that can be folded and unfolded, a curved display panel that has a curved display surface, a curved display panel in which areas other than the display surface are bent, a rollable display panel that can be rolled up and unfolded, or a stretchable display panel.

[0089] The display panel 10 can be made transparent and is a transparent display panel, so that an object or background disposed below the display panel 10 at the lower surface of the display panel 10 can be seen from the upper surface of the display panel 10. Alternatively, the display panel 10 can be a reflective display panel that can reflect objects or backgrounds disposed at the upper surface of the display panel 10.

[0090] The data driver 20 may be mounted on the display panel 10 in the form of an integrated circuit (IC). However, this disclosure is not limited thereto. As an example, the data driver 20 may be mounted on the display circuit board 30.

[0091] Display circuit board 30 can be attached to one side of display panel 10. Display circuit board 30 can be a flexible printed circuit board (FPCB) that can be bent, a rigid printed circuit board (PCB) that is rigid and not easily bent, or a composite printed circuit board including both FPCB and rigid PCB. Touch sensor driver can be mounted on display circuit board 30. Touch sensor driver may include integrated circuits. Touch sensor driver can be electrically connected to touch electrodes of touch screen layer of display panel 10 via display circuit board 30.

[0092] The touchscreen layer of the display panel 10 can sense external inputs, such as a user's touch, using at least one of various touch methods, such as resistive (electrical) layer methods and capacitive (electrical) methods. When the touchscreen layer of the display panel 10 senses external input using a capacitive method, the touch sensor driver can determine whether the external input is touching or near the touch sensor layer by applying a drive signal to the drive electrode in the touch electrode and sensing the voltage charged in the mutual capacitance between the drive electrode and the sensing electrode through the sensing electrode in the touch electrode.

[0093] External input can include contact (e.g., physical or mechanical) touch and proximity (non-contact) touch. Contact touch indicates that the user's finger or input tool, such as a pen, is in direct contact with the cover window 70 disposed on the touchscreen layer. Hovering proximity touch indicates that the user's finger or input tool, such as a pen, is located above or near the cover window 70, at a certain distance from the cover window 70, and is not in contact with it. The touch sensor driver can be configured to transmit sensor data to the main processor based on the sensed voltage, and the main processor can calculate the touch coordinates of the touch input by analyzing the sensor data.

[0094] The controller can be located on the display circuit board 30, wherein the controller is configured to supply driving voltages for driving the pixels, gate drivers (not shown), and / or data drivers 20 of the display panel 10.

[0095] A bracket 60, serving as an intermediate cover for supporting the display panel 10, may be disposed below the display panel 10. The bracket 60 may comprise plastic, metal, or both. The bracket 60 may have a first camera hole CMH1 defined therein and into which a camera device 531 extends; a battery hole BH defined therein and into which a battery 80 is disposed; a cable hole CAH defined therein and through which a cable connected to the display circuit board 30 passes; and component holes CPH defined therein to correspond to one or more of the components 40. When viewed in the third direction (z-axis direction), the component holes CPH may overlap with the components 40 of the main circuit board 50. For reference, when viewed in the third direction (z-axis direction), the display area DA of the display panel 10 may overlap with the components 40 of the main circuit board 50. The bracket 60 may not have component holes CPH when necessary. Each of the aforementioned holes may extend completely through the body of the bracket 60, for example, to be open at both the upper and lower surfaces of the bracket 60, but is not limited thereto.

[0096] Component 40 of electronic device 1 may include a first component 41, a second component 42, a third component 43, and a fourth component 44, each overlapping the display panel 10. Each of the first component 41, the second component 42, the third component 43, and the fourth component 44 may include at least one of a proximity sensor, an illumination sensor, an iris sensor, a facial recognition sensor, and a camera (or image sensor). The proximity sensor, using infrared light, can detect objects like input tools located near the upper surface of electronic device 1, and the illumination sensor can detect the brightness of external light incident on the upper surface of electronic device 1.

In this case, the materials (e.g., solid portions) of the first touch electrode MT1 and the second touch electrode MT2 may not overlap with each emitting region of the organic light-emitting diode. With the mesh structure defining the touch electrode layer by gaps (or openings) between the materials of the touch electrodes, light emitted from the light-emitting element can pass through the touch electrode layer.

[0221] The second touch insulating layer 520 may be disposed on the second touch electrode MT2. The second touch insulating layer 520 may comprise inorganic or organic materials. When the second touch insulating layer 520 comprises inorganic materials, it may comprise at least one of silicon nitride, aluminum nitride, zirconium nitride, titanium nitride, hafnium nitride, tantalum nitride, silicon oxide, aluminum oxide, titanium oxide, tin oxide, cerium oxide, and silicon oxynitride. When the second touch insulating layer 520 comprises organic materials, it may comprise at least one of acrylic resin, methacrylic resin, polyisoprene, vinyl resin, epoxy resin, urethane resin, cellulose resin, and perylene resin.

[0222] In one embodiment, the touch sensor layer 500 may include a first touch electrode MT1, a first touch insulating layer 510, and a second touch electrode MT2, but may not include the second touch insulating layer 520. In this case, the anti-reflective layer 600 may have a structure that covers the second touch electrode MT2.

[0223] An anti-reflective layer 600 can be disposed on the touch sensor layer 500.

[0224] The antireflective layer 600 may include a light-shielding layer 610 and a plurality of color filters. In an embodiment, the antireflective layer 600 may include first to third color filters 620R, 620G, and 620B of different colors corresponding to the first to third organic light-emitting diodes OLED1, OLED2, and OLED3, respectively. Each of the first to third color filters 620R, 620G, and 620B may be provided in multiple forms.

[0225] The light-shielding layer 610 may have first to third upper openings 610OP1, 610OP2, and 610OP3 corresponding to the first to third sub-pixels, respectively. The light-shielding layer 610 may include a first upper opening 610OP1 corresponding to the first emitting region EA1, a second upper opening 610OP2 corresponding to the second emitting region EA2, and a third upper opening 610OP3 corresponding to the third emitting region EA3. Light emitted from the first to third organic light-emitting diodes OLED1, OLED2, and OLED3 can be emitted to the outside of the display panel 10 (or display device DV) through the first to third upper openings 610OP1, 610OP2, and 610OP3 of the light-shielding layer 610.

[0226] The first upper opening 610OP1 of the light-shielding layer 610 can overlap with the first lower opening 225OP1 of the embankment layer 225, the second upper opening 610OP2 can overlap with the second lower opening 225OP2, and the third upper opening 610OP3 can overlap with the third lower opening 225OP3.

[0227] In this specification, the width (or size) of each subpixel represents the width (or size) of the emission region of the organic light-emitting diode implementing each subpixel, and the width (or size) of the emission region may be defined by the width (or size) of the lower opening of the embankment 225. As used herein, the width may be measured along a planar direction (e.g., along the xy plane).

[0228] In this embodiment, the width (or size) of each of the first to third upper openings 610OP1, 610OP2, and 610OP3 of the light-shielding layer 610 can be greater than the width (or size) of the corresponding sub-pixel among the first to third sub-pixels. That is, the width (or size) of the first to third upper openings 610OP1, 610OP2, and 610OP3 of the light-shielding layer 610 can be greater than the width (or size) of the corresponding first to third lower openings 225OP1, 225OP2, and 225OP3 of the dike layer 225, respectively.

[0229] In this embodiment, the width (or size) of each of the first to third upper openings 610OP1, 610OP2, and 610OP3 of the light-shielding layer 610 can be substantially the same as the width (or size) of the corresponding sub-pixel among the first to third sub-pixels. That is, the width (or size) of the first to third upper openings 610OP1, 610OP2, and 610OP3 of the light-shielding layer 610 can be substantially the same as the width (or size) of the corresponding first to third lower openings 225OP1, 225OP2, and 225OP3 of the dam layer 225, respectively.

[0230] The light-shielding layer 610 may include an organic insulating material. Alternatively, the light-shielding layer 610 may include an inorganic insulating material such as silicon nitride or silicon oxide. In embodiments, the light-shielding layer 610 may include both organic and inorganic insulating materials.

[0231] In an embodiment, the light-shielding layer 610 may include a light-shielding material. As an example, the light-shielding material of the light-shielding layer 610 may be black. The light-shielding material may include carbon black, carbon nanotubes, a resin or paste containing a black dye, metal particles (e.g., nickel, aluminum, molybdenum, and their alloys), metal oxide particles, or metal nitride particles. Because the light-shielding layer 610 includes a light-shielding material, external light reflection caused by the metal structure disposed beneath the light-shielding layer 610 can be reduced.

[0232] The first to third color filters 620R, 620G, and 620B can be arranged in the first to third upper openings 610OP1, 610OP2, and 610OP3 of the light-shielding layer 610, respectively. The first to third color filters 620R, 620G, and 620B can have colors corresponding to the light emitted from the first to third emission regions EA1, EA2, and EA3. In an embodiment, when the first emission region EA1 emits red light, the first color filter 620R can be a red filter; when the second emission region EA2 emits green light, the second color filter 620G can be a green filter; and when the third emission region EA3 emits blue light, the third color filter 620B can be a blue filter.

[0233] The antireflective layer 600 may further include a protective layer 630. The protective layer 630 may be disposed on the light-shielding layer 610 and / or the first to third color filters 620R, 620G, and 630B. The protective layer 630 may planarize the upper surface of the light-shielding layer 610 and / or the first to third color filters 620R, 620G, and 630B. The protective layer 630 is a colorless, transparent layer that is colorless in the visible light band. The protective layer 630 may include a colorless, transparent organic material such as an acrylic resin.

[0234] The cover window 70 can be positioned above the protective layer 630, wherein the adhesive layer OCA is located between the cover window 70 and the protective layer 630.

[0235] Figure 12B It is along Figure 11 A cross-sectional view of the display device DV taken by line B-B'. Figure 12B Show Figure 12A This is a modified embodiment of the anti-reflective layer 600. The differences are mainly described below.

[0236] refer to Figure 12B The anti-reflective layer 600 may consist of only multiple color filters, without the light-shielding layer 610 (see...). Figure 12A ).

[0237] In an embodiment, the third color filter 620B, the first color filter 620R, and the second color filter 620G can be stacked sequentially in a direction away from the substrate 100 (+z direction).

[0238] The third color filter 620B can be configured to allow most of blue light to pass through while blocking most of red or green light. The third color filter 620B may include a third opening 620BOP corresponding to the second emission region EA2 and the first emission region EA1. The third color filter 620B may include the third opening 620BOP such that green light and red light emitted from the second emission region EA2 and the first emission region EA1, respectively, are not blocked. Most of the blue light emitted from the third emission region EA3 can pass through the third color filter 620B and be emitted to the outside.

[0239] The first color filter 620R can be configured to allow most of red light to pass through while blocking most of blue or green light. The first color filter 620R can fill some of the third opening 620BOP of the third color filter 620B that corresponds to the first emission region EA1, and can be disposed on the third color filter 620B. The first color filter 620R may include a first opening 620ROP corresponding to the second emission region EA2 and the third emission region EA3. The first color filter 620R may include the first opening 620ROP such that green light and blue light emitted from the second emission region EA2 and the third emission region EA3, respectively, are not blocked. Most of the red light emitted from the first emission region EA1 can pass through the first color filter 620R and be emitted to the outside.

[0240] The second color filter 620G can be configured to allow most of green light to pass through while blocking most of red or blue light. The second color filter 620G can fill a portion of the third opening 620BOP of the third color filter 620B corresponding to the second emission region EA2, and a portion of the first opening 620ROP of the first color filter 620R corresponding to the second emission region EA2, and can be disposed on the first color filter 620R. The second color filter 620G may include a second opening 620GOP corresponding to the first emission region EA1 and the third emission region EA3. The second color filter 620G may include a second opening 620GOP such that red and blue light emitted from the first emission region EA1 and the third emission region EA3, respectively, are not blocked. Most of the green light emitted from the second emission region EA2 can pass through the second color filter 620G and be emitted to the outside.

[0241] The antireflective layer 600 may have a light-shielding portion BP in the portion corresponding to the space between the first to third emission regions EA1, EA2, and EA3 or the space between the sub-pixel electrodes 210R, 210G, and 210B. Here, the light-shielding portion BP includes the first to third color filters 620R, 620G, and 620B stacked to overlap each other. The light-shielding portion BP can be configured to remain in place even without the light-shielding layer 610 including black light-shielding material (see...). Figure 12AIt also blocks light in cases where it is not in use. In addition, it can reduce external light reflection from the display device (DV).

[0242] In this embodiment, the width (size) of the first opening 620ROP of the first color filter 620R, which overlaps with the second emission region EA2 of the second sub-pixel, can be greater than the width (size) of the third opening 620BOP of the third color filter 620B. The width (size) of the second opening 620GOP of the second color filter 620G, which overlaps with the third emission region EA3 of the third sub-pixel, can be greater than the width (size) of the first opening 620ROP of the first color filter 620R. The width (size) of the second opening 620GOP of the second color filter 620G, which overlaps with the first emission region EA1 of the first sub-pixel, can be greater than the width (size) of the third opening 620BOP of the third color filter 620B.

[0243] Within the openings at each sub-pixel, the light-emitting region of the sub-pixel can be defined by the opening (or emitting region) of the anti-reflective layer 600, while the non-emitting region between the light-emitting regions can be defined by the material of the anti-reflective layer 600. Figure 12A In this context, the non-emissive area can be defined by a planar region of the light-shielding layer 610 (e.g., its maximum width). Figure 12B In this context, the non-emissive region can be defined by a planar region of the shading portion BP that is common to each of the overlapping color filter portions.

[0244] Figures 13A to 13H yes Figure 11 A schematic plan view of an embodiment of the opening shown in the figure.

[0245] refer to Figures 13A to 13H An opening CH, which is defined in one of the first, second, and third openings in the counter electrode 230, can have various types of planar shapes. When multiple openings CH are defined in the same emission region, such an opening can be referred to as a sub-opening.

[0246] As an example, the planar shape of the opening CH, which is a sub-opening in the same emission region, can be a polygonal shape, a circular shape, and / or an elliptical shape. In embodiments, the opening CH can have an irregular shape other than a polygonal shape, a circular shape, and / or an elliptical shape. As an example, the opening CH can have such... Figure 13H The star-shaped planar shape is shown in the figure.

[0247] The maximum internal width of the opening CH can range from approximately 1 micrometer (µm) to approximately 10 micrometers (µm). As an example, the planar shape of the opening CH is square. Figure 13A In the case of ), the first length LH1 of one side of the opening CH can be in the range of about 1µm to about 10µm.

[0248] The planar shape of the opening CH is circular. Figure 13B In the case of an opening CH, the diameter LH2 can range from approximately 1 µm to approximately 10 µm. When the planar shape of the opening CH is elliptical (…), Figure 13C In the case of ), the second length LH3 of the major axis of the opening CH can be in the range of about 1µm to about 10µm.

[0249] The shape of the plane at the opening CH is rectangular. Figure 13D and Figure 13E In the case of ), regardless of the direction of extension of the long side of the rectangle, the third lengths LH4 and LH5 of the long side of the opening CH can be in the range of approximately 1µm to approximately 10µm.

[0250] The shape of the plane with opening CH is triangular. Figure 13F In the case of a triangle, the fourth length LH6 of the longest side among the three sides can be in the range of approximately 1µm to approximately 10µm.

[0251] The shape of the plane with opening CH is pentagonal. Figure 13G In the case of ), the fifth length LH7, which has the maximum length inside the pentagon, can be in the range of approximately 1µm to approximately 10µm.

[0252] The planar shape of the opening CH is such as a star ( Figure 13H In the case of an irregular shape, the sixth length LH8, which has the maximum length inside the planar shape of the opening CH, can be in the range of about 1µm to about 10µm.

[0253] When the length of the maximum width in the planar shape of the opening CH is less than 1µm, the reflection banding caused by external light reflection will not be reduced because external light will not be reflected in all directions through the opening CH. When the length of the maximum width in the planar shape of the opening CH exceeds 10µm, the brightness of each organic light-emitting diode may be reduced because a preset voltage can be applied to each intermediate layer.
