[0003] One or more embodiments relate to a display device including a light emitting diode. Background Art

[0004] Display devices display data visually. Display devices can provide images by using light emitting diodes. The uses of display devices have been diversified. Various attempts have been made to design transparent display devices that allow objects behind the display device to be visible while displaying images.

[0005] It should be understood that this background section is intended, in part, to provide a useful background for understanding the technology.

Summary of the invention

[0006] The display device may include a pixel region in which pixels for displaying an image are arranged and a transmissive region in which no pixels are arranged. As the transmittance in the transmissive region increases, the transparency of the display device may increase. Therefore, in order to realize a transparent display device that allows objects behind the display device to be visible while displaying an image, it is necessary to increase the transmittance in the transmissive region.

[0047] Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. In this regard, embodiments may have different forms and should not be construed as being limited to the descriptions set forth herein. Accordingly, embodiments are described below with reference to the accompanying drawings to explain various aspects of the present description.

[0048] In this specification and claims, for the purpose of its meaning and interpretation, the term "and / or" is intended to include any combination of the terms "and" and "or". For example, "A and / or B" may be understood to mean "A, B, or A and B". The terms "and" and "or" may be used in either a conjunctive or disjunctive sense and may be understood to be equivalent to "and / or".

[0049] In this specification and claims, for the purpose of its meaning and interpretation, the phrase "at least one of" is intended to include the meaning of "at least one selected from the group of". For example, "at least one of A and B" may be understood to mean "A, B, or A and B".

[0050] Since the present description allows for various variations and numerous embodiments, each embodiment will be illustrated in the drawings and described in detail in the written description. The effects and features of the present disclosure and methods for achieving them will be explained with reference to the embodiments described in detail below with reference to the drawings. However, the present disclosure is not limited to the following embodiments and may be embodied in various forms.

[0051] Hereinafter, various embodiments will be described in detail with reference to the accompanying drawings. When various embodiments are described with reference to the accompanying drawings, the same or corresponding elements are represented by the same reference numerals.

[0052] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present disclosure.

[0053] As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0054] It will be further understood that when used in this specification, the terms "comprises" and / or "includes" and / or "has" and variations thereof indicate the presence of stated features, integers, steps, operations, elements, parts and / or groups thereof, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, parts and / or groups thereof.

[0055] It will be further understood that when a layer, region or element is referred to as being “on” another layer, region or element, it can be directly or indirectly on the other layer, region or element. For example, intervening layers, regions or elements may be present.

[0056] The term "overlap" or "overlapping" means that a first object can be above or below or to the side of a second object, and vice versa. In addition, the term "overlap" may include stacking, stacking, facing or facing, extending over, covering or partially covering, or any other appropriate term that a person of ordinary skill in the art will appreciate and understand.

[0057] When an element is described as “not overlapping” or “so as not to “overlap” another element, this may include the elements being spaced apart, offset or separated from each other, or any other appropriate terminology as would be appreciated and understood by one of ordinary skill in the art.

[0058] The terms "facing" and "facing" mean that the first element can be directly or indirectly opposite to the second element. In the case where a third element is interposed between the first and second elements, the first and second elements can be understood to be indirectly opposite to each other, although still facing each other.

[0059] In addition, for the convenience of explanation, the size of the elements in the drawings may be exaggerated or reduced. For example, because the size and thickness of the elements in the drawings are arbitrarily illustrated for the convenience of explanation, the present disclosure is not limited thereto.

[0060] When the embodiment can be implemented differently, a specific process order can be performed differently from the described order. For example, two processes described in succession can be performed substantially simultaneously or in the reverse order of the described order.

[0061] It will be further understood that when layers, regions, or elements are referred to as being connected or coupled to each other, they may be directly connected or coupled to each other, or indirectly connected or coupled to each other, with intervening layers, regions, or elements located therebetween. For example, when layers, regions, or elements are referred to as being electrically connected to each other, they may be directly electrically connected to each other, or indirectly electrically connected to each other, with intervening layers, regions, or elements located therebetween.

[0062] It will be understood that the terms "connected to" or "coupled to" may include physical or electrical connections or couplings.

[0063] The ±x direction, ±y direction, and ±z direction are not limited to directions corresponding to the three axes of the rectangular coordinate system and can be interpreted in a broader sense. For example, the ±x direction, ±y direction, and ±z direction may be perpendicular to each other, or may represent different directions that are not perpendicular to each other.

[0064] As used herein, "about" or "approximately" includes the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, taking into account the measurement in question and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or within ±30%, ±20%, ±10%, ±5% of the stated value.

[0065] Unless otherwise defined or implied herein, all terms (including technical and scientific terms) used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. It will be further understood that terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and unless explicitly defined as such herein, these terms will not be interpreted in an idealized or overly formal sense.

[0066] Figure 1 is a schematic perspective view schematically illustrating a display device 1 according to the embodiment.

[0067] refer to Figure 1 , the display device 1 may include a display area DA and a non-display area NDA outside the display area DA. The display area DA is an area that displays an image by pixels P arranged (or set) therein. The non-display area NDA is an area outside the display area DA and may completely surround the display area DA. No image is displayed in the non-display area NDA. A driver or the like that supplies an electrical signal or power to the display area DA may be arranged in the non-display area NDA. A pad that is an area to which an electronic component or a printed circuit board can be electrically connected may be arranged in the non-display area NDA.

[0068] In an embodiment, Figure 1 The figure shows that the display area DA has a polygonal shape (e.g., a rectangular shape) in which the length of the display area DA in the ±x direction is smaller than the length of the display area DA in the ±y direction, but in an embodiment, the display area DA may have a polygonal shape (e.g., a rectangular shape) in which the length of the display area DA in the ±y direction is smaller than the length of the display area DA in the ±x direction. Figure 1 The display area DA is shown to have a substantially rectangular shape, but the present disclosure is not limited thereto. In an embodiment, the display area DA may have various shapes such as an N-gonal shape (where N is a natural number greater than or equal to 3), a circular shape, or an elliptical shape other than a rectangular shape. Figure 1 The diagram illustrates that the corner portions of the display area DA include vertices at which straight lines intersect each other, but in an embodiment, the display area DA may have a polygonal shape with rounded corner portions.

[0069] The display area DA may include a pixel area PA and a transmissive area TA.

[0070] The corresponding pixels P may be arranged in the pixel area PA. A plurality of pixel areas PA and a plurality of pixels P may be provided. Each of the plurality of pixels P may provide a selectable image by emitting light L1.

[0071] The transmission area TA may be arranged adjacent to the pixel area PA and may transmit light. Light L2 incident on one surface (or one surface) of the display device 1 in the transmission area TA may pass through the display device 1 and travel to the opposite surface of the display device 1. For example, light L2 incident on the -z direction surface of the display device 1 in the +z direction in the transmission area TA may pass through the display device 1 and exit from the +z direction surface of the display device 1. A plurality of transmission areas TA may be provided.

[0072] Accordingly, the display device 1 can provide an image by using the light L1 emitted from the pixel P, and can also display an image from the rear (e.g., -z direction) of the display device 1 by transmitting the light L2 incident in the transmission area TA. In other words, the display device 1 can be a transparent display device that can display an image provided by the display device 1 and an image from the rear (e.g., -z direction) of the display device 1.

[0073] FIG. 2A to FIG. 2E is a schematic plan view schematically illustrating a portion of a display device according to various embodiments.

[0074] refer to Figure 2A , the display area DA may include a pixel area PA and a transmission area TA.

[0075] The pixels P may be arranged in the pixel area PA. Figure 2A The figure shows that one pixel P is arranged in one pixel area PA. However, in an embodiment, a plurality of pixels P may be arranged in one pixel area PA (see Figure 2D ).

[0076] The pixels P may be arranged in one direction (or one direction). For example, the pixels P may be spaced apart from each other in the ±x direction. The pixels P spaced apart from each other in the ±x direction may form a row. As an example, it may be understood that the pixel areas PA spaced apart from each other in the ±x direction form a row.

[0077] The transmission areas TA may be arranged in one direction. For example, the transmission areas TA may be spaced apart from each other in the ±x directions. The transmission areas TA spaced apart from each other in the ±x directions may form a row.

[0078] The row of the transmission area TA may be disposed above and / or below (or in the ±y direction) the row of pixels P (or the row of pixel areas PA). The row of pixels P (or the row of pixel areas PA) may be disposed above and / or below (or in the ±y direction) the row of the transmission area TA.

[0079] In other words, rows consisting of pixels P arranged in the ±x directions (or rows consisting of pixel areas PA arranged in the ±x directions) and rows consisting of transmission areas TA arranged in the ±x directions may be alternately arranged in the ±y directions.

[0080] As another example, when viewed based on the ±y directions, the pixel areas PA and the transmission areas TA may be alternately arranged in the ±y directions to form rows, and it may be understood that corresponding columns are arranged in the ±x directions.

[0081] One pixel P may include a plurality of sub-pixels. For example, the pixel P may include first to third sub-pixels SP1, SP2, and SP3. The first to third sub-pixels SP1, SP2, and SP3 may be arranged in the same pixel area PA.

[0082] The first to third sub-pixels SP1, SP2, and SP3 may be spaced apart from each other in the same pixel area PA. For example, the third sub-pixel SP3 may be arranged in the right region (or +x side region) of one pixel area PA, the first sub-pixel SP1 may be arranged in the upper left region (or -x and +y side regions), and the second sub-pixel SP2 may be arranged in the lower left region (or -x and -y side regions).

[0083] The areas of the first to third subpixels SP1, SP2, and SP3 may be different from each other. For example, the area of ​​the first subpixel SP1 may be greater than that of the second subpixel SP2, and the area of ​​the third subpixel SP3 may be greater than that of the first subpixel SP1.

[0084] The first to third sub-pixels SP1, SP2, and SP3 may emit light of different colors. For example, the first sub-pixel SP1 may emit red light. The second sub-pixel SP2 may emit green light. The third sub-pixel SP3 may emit blue light. The pixel P may provide light of any color (e.g., Figure 1 Light L1 shown in the figure).

[0085] In an embodiment, the present disclosure is not limited to the areas and arrangements of the first to third sub-pixels SP1, SP2, and SP3 and the colors of light emitted from the first to third sub-pixels SP1, SP2, and SP3. The areas and arrangements of the first to third sub-pixels SP1, SP2, and SP3 and the colors of light emitted from the first to third sub-pixels SP1, SP2, and SP3 may be changed variously.

[0086] The auxiliary electrode AE ​​may be located between the pixel area PA and the transmission area TA. The auxiliary electrode AE ​​may extend in the ±x direction and / or the ±y direction. For example, a portion of the auxiliary electrode AE ​​may extend between the pixel area PA and the transmission area TA adjacent to each other. In an embodiment, the auxiliary electrode AE ​​may extend in the ±x direction and the ±y direction and surround the pixel area PA and the transmission area TA.

[0087] In other words, the auxiliary electrode AE ​​may have a substantially mesh structure, and the pixel area PA or the transmission area TA may be arranged in each hole of the mesh structure of the auxiliary electrode AE. As an example, it can be understood that the auxiliary electrode AE ​​has a mesh structure and divides the display area DA into the pixel area PA and the transmission area TA.

[0088] In an embodiment, the auxiliary electrode AE ​​surrounding one pixel area PA and the auxiliary electrode AE ​​surrounding an adjacent pixel area PA may share a portion with each other. For example, the right side portion (or +x direction portion) of the auxiliary electrode AE ​​surrounding one pixel area PA may be substantially the same as the left side portion (or -x direction portion) of the auxiliary electrode AE ​​surrounding the pixel area PA arranged on the right side (or +x direction).

[0089] In an embodiment, the auxiliary electrode AE ​​surrounding one pixel area PA and the auxiliary electrode AE ​​surrounding an adjacent transmission area TA may share a portion with each other. For example, the lower portion (or -y direction portion) of the auxiliary electrode AE ​​surrounding one pixel area PA may be substantially the same as the upper portion (or +y direction portion) of the auxiliary electrode AE ​​surrounding the transmission area TA arranged below (or -y direction).

[0090] refer to Figure 2B ,and Figure 2A Compared to the embodiment illustrated in FIG. 2 , the auxiliary electrode AE ​​may further include additional structures extending in the ±y directions.

[0091] In an embodiment, the auxiliary electrode AE ​​surrounding one pixel area PA and the auxiliary electrode AE ​​surrounding an adjacent pixel area PA may not share a portion with each other. For example, the right side portion (or +x direction portion) of the auxiliary electrode AE ​​surrounding one pixel area PA may be separated from the left side portion (or -x direction portion) of the auxiliary electrode AE ​​surrounding the pixel area PA arranged on the right side (or +x direction).

[0092] In other words, the two portions of the auxiliary electrode AE ​​extending in the ±y directions may be spaced apart from each other between two adjacent pixel areas PA. Accordingly, the two portions of the auxiliary electrode AE ​​and a space defined between the two portions of the auxiliary electrode AE ​​and having a relatively small size compared to the pixel area PA may be located between two adjacent pixel areas PA.

[0093] This structure of the auxiliary electrode AE ​​and the space can prevent the counter electrodes arranged in two adjacent pixel areas PA described below from contacting each other when the counter electrodes are arranged in the pixel area PA and extend onto the auxiliary electrode AE. Because the area of ​​the auxiliary electrode AE ​​is increased, the effect of reducing the resistance in the auxiliary electrode AE ​​can be obtained.

[0094] refer to Figure 2C , the arrangement of the pixel area PA and the transmission area TA may be different from Figure 2A The arrangement of the embodiment illustrated in FIG.

[0095] In an embodiment, the pixel areas PA and the transmission areas TA may be arranged alternately in the ±x direction and the ±y direction. The arrangement of the pixels P (or the arrangement of the pixel areas PA) and the arrangement of the transmission areas TA may cross each other. For example, the arrangement of the pixels P (or the arrangement of the pixel areas PA) extending in the first direction DR1 and the arrangement of the transmission areas TA extending in the first direction DR1 may alternate in the second direction DR2. As an example, the arrangement of the pixels P (or the arrangement of the pixel areas PA) extending in the second direction DR2 and the arrangement of the transmission areas TA extending in the second direction DR2 may alternate in the first direction DR1.

[0096] When viewed based on one pixel area PA, the transmission area TA may be arranged at the top, bottom, left and right sides (or ±x and ±y directions) of the pixel area PA. Another pixel area PA may be arranged in an oblique direction (or in the first direction DR1 or the second direction DR2) of the pixel area PA.

[0097] When viewed based on one transmission area TA, the pixel area PA may be arranged above and below the transmission area TA and to the left and right of the transmission area TA (or ±x direction and ±y direction). Another transmission area TA may be arranged in the oblique direction of the transmission area TA (or in the first direction DR1 or the second direction DR2).

[0098] In an embodiment, the pixels P may be spaced apart from each other in the oblique directions of the ±x and ±y directions (e.g., in the first direction DR1 and the second direction DR2). As an example, it can be understood that the pixel areas PA are spaced apart from each other in the first direction DR1 and the second direction DR2. Similarly, the transmission areas TA may be spaced apart from each other in the oblique directions of the ±x and ±y directions (e.g., in the first direction DR1 and the second direction DR2).

[0099] refer to Figure 2D , the auxiliary electrode AE ​​may extend in the ±x direction.

[0100] The auxiliary electrode AE ​​may extend in the ±x direction and may divide the display area DA into the pixel area PA and the transmission area TA. As an example, a plurality of auxiliary electrodes AE extending in the ±x direction may be provided. It is understood that the auxiliary electrode AE ​​is arranged in the ±y direction and divides the display area DA into the pixel area PA and the transmission area TA.

[0101] The pixel areas PA and the transmission areas TA may each have a shape extending in the ±x direction, and may be alternately arranged in the ±y direction. The auxiliary electrode AE ​​may be located between one pixel area PA and one transmission area TA adjacent to each other among the alternately arranged pixel areas PA and the transmission areas TA. In other words, one pixel area PA or one transmission area TA may be located between two adjacent auxiliary electrodes AE arranged in the ±y direction.

[0102] It is understandable that by Figure 2A The auxiliary electrode AE ​​is obtained by removing the portion extending in the ±y directions from the auxiliary electrode AE ​​of the embodiment shown in FIG.

[0103] In an embodiment, a plurality of pixels P may be arranged in one pixel area PA. For example, the pixel area PA may have a shape extending in the ±x directions, and the pixels P may be arranged in the pixel area PA in the ±x directions.

[0104] Figure 2DThe figure shows that the pixel area PA and the transmission area TA each have a shape extending in the ±x direction and are alternately arranged in the ±y direction, but the present disclosure is not limited thereto. In an embodiment, the pixel area PA and the transmission area TA each have a shape extending in the ±y direction and may be alternately arranged in the ±x direction. The auxiliary electrode AE ​​may have a shape extending in the ±y direction and may be located between the pixel area PA and the transmission area TA adjacent to each other.

[0105] refer to Figure 2E , the auxiliary electrode AE ​​may extend in the ±y direction.

[0106] The arrangement of the pixel P (or pixel area PA) and the transmission area TA may be similar to that of the reference Figure 2A The arrangement described is the same.

[0128] The first to third sub-pixel electrodes 1210 , 2210 , and 3210 may be electrically connected to the overlapping connection metal CM through contact holes formed in the second organic insulating layer 109 .

[0129] According to reference Figure 3A In the described embodiment, the first to third thin film transistors TFT1, TFT2 and TFT3 and the first to third sub-pixel electrodes 1210, 2210 and 3210 are shown to be electrically connected to each other through the connection metal CM, but the present disclosure is not limited thereto. In an embodiment, the connection metal CM may be omitted, and one organic insulating layer may be located between the first to third thin film transistors TFT1, TFT2 and TFT3 and the first to third sub-pixel electrodes 1210, 2210 and 3210. As an example, three or more organic insulating layers may be located between the first to third thin film transistors TFT1, TFT2 and TFT3 and the first to third sub-pixel electrodes 1210, 2210 and 3210, and the first to third thin film transistors TFT1, TFT2 and TFT3 may be electrically connected to the first to third sub-pixel electrodes 1210, 2210 and 3210, respectively, through the connection metal.

[0130] The bank layer 111 may cover edge regions (or edges) of the first to third sub-pixel electrodes 1210, 2210, and 3210.

An edge region (or edge) of the second display element DPE2 may be disposed on a portion of the bank layer 111 that overlaps with an edge region (or edge) of the second sub-pixel electrode 2210. An edge region (or edge) of the third display element DPE3 may be disposed on a portion of the bank layer 111 that overlaps with an edge region (or edge) of the third sub-pixel electrode 3210. Therefore, a portion of the bank layer 111 may be located between an edge region (or edge) of each of the first to third display elements DPE1, DPE2, and DPE3 and an edge region (or edge) of each of the first to third sub-pixel electrodes 1210, 2210, and 3210.

The auxiliary electrode AE ​​may be disposed on the bank layer 111 and may be located between the third subpixel SP3 and the transmission area TA adjacent to the third subpixel SP3.

In an embodiment, the auxiliary electrode AE ​​may be located between the first sub-pixel SP1 and the second sub-pixel SP2 and / or between the second sub-pixel SP2 and the third sub-pixel SP3 (see Fig.12 and Fig.14 ).

[0138] Figure 3AThe figure shows that the first display element DPE1 and the third display element DPE3 are spaced apart from the auxiliary electrode AE, but the present disclosure is not limited thereto. In an embodiment, the first display element DPE1 and the third display element DPE3 may be in contact with the auxiliary electrode AE ​​adjacent thereto, respectively.

[0139] The encapsulation layer 300 may be disposed to cover the first to third light emitting diodes OLED1, OLED2, and OLED3, the bank layer 111, and the auxiliary electrode AE. The encapsulation layer 300 may include at least one inorganic encapsulation layer and at least one organic encapsulation layer. For example, the encapsulation layer 300 may include a first inorganic encapsulation layer 310 disposed on the first to third light emitting diodes OLED1, OLED2, and OLED3, a second inorganic encapsulation layer 330, and an organic encapsulation layer 320 located between the first inorganic encapsulation layer 310 and the second inorganic encapsulation layer 330.

[0140] The first inorganic encapsulation layer 310 may overlap with and cover the first to third light emitting diodes OLED1 , OLED2 , and OLED3 and the auxiliary electrode AE.

[0143] The organic encapsulation layer 320 may include at least one organic insulating material selected from the group consisting of PET, PEN, PC, PI, PES, polyoxymethylene (POM), PAR, and HMDSO.

[0144] The encapsulation layer 300 may be disposed to cover all of the transmission area TA, the pixel area PA, and the auxiliary electrode AE. A portion of each of the first inorganic encapsulation layer 310 and the organic encapsulation layer 320 may be disposed in the second opening OP2 of the bank layer 111. The first inorganic encapsulation layer 310 and the organic encapsulation layer 320 may at least partially (e.g., completely) fill the second opening OP2. Since the bank layer 111 is not disposed in the transmission area TA, the first inorganic encapsulation layer 310 may be in direct contact with the second organic insulating layer 109 in the transmission area TA.

[0145] Figure 3B Can be Figure 2A A schematic cross-sectional view of one example among several examples of embodiments taken along line III-III'.

[0148] For example, the gate insulating layer 103, the interlayer insulating layer 105, the first organic insulating layer 107, and / or the second organic insulating layer 109 may each include an opening overlapping the transmission area TA. The openings of the gate insulating layer 103, the interlayer insulating layer 105, the first organic insulating layer 107, and / or the second organic insulating layer 109 may overlap the second opening OP2 of the bank layer 111. In other words, the gate insulating layer 103, the interlayer insulating layer 105, the first organic insulating layer 107, the second organic insulating layer 109, and the bank layer 111 may not be arranged in the transmission area TA.

[0149] Understandably, Figure 3B The embodiment shown in the figure is realized by Figure 3A In the embodiment shown in FIG. 1 , the gate insulating layer 103 , the interlayer insulating layer 105 , the first organic insulating layer 107 and the second organic insulating layer 109 in the range overlapping with the transmission area TA are removed.

[0150] A portion of the first inorganic encapsulating layer 310 and a portion of the organic encapsulating layer 320 may be disposed in an opening formed through the gate insulating layer 103, the interlayer insulating layer 105, the first organic insulating layer 107, and the second organic insulating layer 109 in the transmission area TA. For example, the first inorganic encapsulating layer 310 and the organic encapsulating layer 320 may at least partially (e.g., completely) fill the opening formed through the gate insulating layer 103, the interlayer insulating layer 105, the first organic insulating layer 107, and the second organic insulating layer 109 in the transmission area TA.

The first inorganic encapsulating layer 310 may directly contact an upper surface of the buffer layer 101 in the transmission area TA.

[0152] Figure 3B The figure shows that the insulating layer between the substrate 100 and the first to third sub-pixel electrodes 1210, 2210 and 3210 includes an opening corresponding to the transmission area TA, but the present disclosure is not limited thereto. Therefore, one or more insulating layers selected from the bank layer 111, the second organic insulating layer 109, the first organic insulating layer 107, the interlayer insulating layer 105 and the gate insulating layer 103 may include an opening corresponding to the transmission area TA.

[0154] One of the various embodiments may also include an embodiment in which the embankment layer 111, the second organic insulating layer 109 and the first organic insulating layer 107 are removed from the transmission area TA, for example, an embodiment in which the embankment layer 111, the second organic insulating layer 109 and the first organic insulating layer 107 include an opening overlapping the transmission area TA and the first inorganic encapsulation layer 310 is in direct contact with the interlayer insulating layer 105 in the transmission area TA.

The sub-pixel circuit PC may include a driving thin film transistor Td, a switching thin film transistor Ts, and a storage capacitor Cst. The sub-pixel SP may emit light of a selectable color through the light emitting diode OLED. For example, the sub-pixel SP may emit red light, green light, or blue light through the light emitting diode OLED, or may emit red light, green light, blue light, or white light through the light emitting diode OLED.

[0158] The switching thin film transistor Ts may be connected to the scan line SL and the data line DL and may transfer a data voltage or a data signal Dm input from the data line DL to the driving thin film transistor Td in response to a scan voltage or a scan signal Sn input from the scan line SL.

[0159] The storage capacitor Cst may be connected to the switching thin film transistor Ts and the driving voltage line PL, and may store a voltage corresponding to a difference between a voltage received from the switching thin film transistor Ts and a first power source voltage ELVDD supplied to the driving voltage line PL.

[0160] The driving thin film transistor Td may be connected to the driving voltage line PL and the storage capacitor Cst, and may control the driving current flowing from the driving voltage line PL to the light emitting diode OLED according to the value of the voltage stored in the storage capacitor Cst. The light emitting diode OLED may emit light with selectable brightness according to the driving current. The counter electrode (e.g., cathode) of the light emitting diode OLED may receive the second power supply voltage ELVSS. In an embodiment, the counter electrode of the light emitting diode OLED may receive the second power supply voltage ELVSS through the auxiliary electrode.

[0161] Figure 4 The figure shows that the sub-pixel circuit PC may include two thin film transistors and one storage capacitor, but the present disclosure is not limited thereto, and the sub-pixel circuit PC may include three or more thin film transistors.

[0162] Figure 5 is an enlarged schematic plan view illustrating a part of the display device according to the embodiment.

[0163] For example, Figure 5 Can be Figure 2Cis an enlarged view of a portion of the embodiment illustrated in . Accordingly, the transmission area TA can be arranged at the top, bottom, left and right sides (or ±x directions and ±y directions) of the pixel area PA. The following description will focus on the case where the transmission area TA is arranged at the top, bottom, left and right sides (or ±x directions and ±y directions) of the pixel area PA. However, the present disclosure is not limited thereto, and the following description can be similarly applied to the case where the transmission area TA is arranged at the top and bottom (or ±y directions) of the pixel area PA (see Figure 2A , Figure 2B , Figure 2D as well as Figure 2E ) or the case where the transmission area TA is arranged on the left and right sides (or ±x directions) of the pixel area PA.

[0164] refer to Figure 5 , the auxiliary electrode AE ​​may be disposed to surround the pixel area PA, and the transmission area TA may be arranged around the pixel area PA. For example, the transmission area TA may be arranged at the top, bottom, left, and right sides (or ±x and ±y directions) of the pixel area PA. The pixel area PA and the transmission area TA may be spaced apart from each other by the auxiliary electrode AE.

[0165] The first to third sub-pixels SP1, SP2, and SP3 may be arranged in the pixel area PA. The auxiliary electrode AE ​​may substantially surround the first to third sub-pixels SP1, SP2, and SP3.

[0166] The first to third sub-pixels SP1, SP2, and SP3 may include first to third intermediate layers 1220, 2220, and 3220, and first to third counter electrodes 1230, 2230, and 3230, respectively. For example, the first sub-pixel SP1 may include a first intermediate layer 1220 and a first counter electrode 1230. The second sub-pixel SP2 may include a second intermediate layer 2220 and a second counter electrode 2230. The third sub-pixel SP3 may include a third intermediate layer 3220 and a third counter electrode 3230.

[0167] The first to third intermediate layers 1220, 2220, and 3220 may include materials that emit light of different colors when a voltage is applied thereto. For example, the first intermediate layer 1220 may include a material that emits red light. The second intermediate layer 2220 may include a material that emits green light. The third intermediate layer 3220 may include a material that emits blue light.

[0168] Accordingly, the first to third sub-pixels SP1, SP2, and SP3 may emit light of different colors. For example, the first sub-pixel SP1 may emit red light, the second sub-pixel SP2 may emit green light, and the third sub-pixel SP3 may emit blue light.

[0169] The areas of the first to third counter electrodes 1230, 2230, and 3230 may be respectively larger than the areas of the first to third intermediate layers 1220, 2220, and 3220. For example, the area of ​​the first counter electrode 1230 may be larger than the area of ​​the first intermediate layer 1220. Accordingly, when viewed from the +z direction, the first counter electrode 1230 may completely cover the first intermediate layer 1220. The area of ​​the second counter electrode 2230 may be larger than the area of ​​the second intermediate layer 2220. Accordingly, when viewed from the +z direction, the second counter electrode 2230 may completely cover the second intermediate layer 2220. The area of ​​the third counter electrode 3230 may be larger than the area of ​​the third intermediate layer 3220. Accordingly, when viewed from the +z direction, the third counter electrode 3230 may completely cover the third intermediate layer 3220.

[0170] The first to third sub-pixels SP1, SP2, and SP3 may have an island shape spaced apart from each other. For example, the first to third intermediate layers 1220, 2220, and 3220 may be spaced apart from each other. The first to third counter electrodes 1230, 2230, and 3230 may be spaced apart from each other.

[0171] The auxiliary electrode AE ​​may include 1-1 to 1-4 portions AE1-1, AE1-2, AE1-3, and AE1-4. The 1-1 portion AE1-1 may be disposed at the top of the pixel area PA (or the +y direction) and may extend in the ±x direction. The 1-2 portion AE1-2 may be disposed at the left side of the pixel area PA (or the -x direction) and may extend in the ±y direction. The 1-3 portion AE1-3 may be disposed at the bottom of the pixel area PA (or the -y direction) and may extend in the ±x direction. The 1-4 portion AE1-4 may be disposed at the right side of the pixel area PA (or the +x direction) and may extend in the ±y direction.

[0172] The first to third pairs of electrodes 1230, 2230, and 3230 may be disposed on the first to third intermediate layers 1220, 2220, and 3220, respectively, may extend in one direction, and may contact the auxiliary electrode AE.

[0214] FIG. 8A to FIG. 8C is an enlarged schematic cross-sectional view illustrating a portion of a display device according to various embodiments.

[0215] Fig. 8A The embodiment illustrated in the figure may be a diagram showing Figure 6 One of several examples of enlarged region VIII in the embodiment illustrated in FIG.

[0216] refer to Fig. 8A The auxiliary electrode 1-2 portion AE1-2 and the first intermediate layer 1220 may be disposed on the bank layer 111. The first pair of electrodes 1230 may be disposed to cover a portion of an upper surface of the auxiliary electrode 1-2 portion AE1-2 and the first intermediate layer 1220.

[0217] The 1-2 portion AE1-2 and the first intermediate layer 1220 may be spaced apart from each other. In an embodiment, the 1-2 portion AE1-2 and the first intermediate layer 1220 may be spaced apart from each other, and a portion of the first counter electrode 1230 may directly contact the bank layer 111 between the 1-2 portion AE1-2 and the first intermediate layer 1220.

[0218] The thickness t2 of the first intermediate layer 1220 may be greater than the thickness t1 of the 1-2 portion AE1-2. However, the present disclosure is not necessarily limited thereto, and in an embodiment, the thickness t2 of the first intermediate layer 1220 may be substantially equal to the thickness t1 of the 1-2 portion AE1-2.

[0219] Figure 8B The embodiment illustrated in the figure may be a diagram showing Figure 6Another one of several examples of the enlarged region VIII in the embodiment illustrated in FIG.

[0220] refer to Figure 8B , the 1-2 portion AE1-2 and the first intermediate layer 1220 may be in direct contact with each other. For example, one surface of the 1-2 portion AE1-2 may be in contact with one surface of the first intermediate layer 1220. A portion of the first intermediate layer 1220 (for example, a portion of the 1-1 functional layer 1221) may be disposed on a side surface of the 1-2 portion AE1-2 facing the first intermediate layer 1220. Accordingly, the 1-2 portion AE1-2 may have a shape that appears to be drilled into a portion of the side surface of the first intermediate layer 1220. In other words, the first intermediate layer 1220 may cover a portion of the side surface of the 1-2 portion AE1-2.

[0221] Figure 8C The embodiment illustrated in the figure may be a diagram showing Figure 6 0 is another one of several examples of the enlarged region VIII in the embodiment illustrated in FIG.

[0222] refer to Figure 8C , the first intermediate layer 1220 may cover a portion of the side surface and the upper surface of the 1-2 portion AE1-2. Therefore, a portion of the first intermediate layer 1220 (e.g., a portion of the 1-2 functional layer 1223) may be disposed on the upper surface of the 1-2 portion AE1-2. A portion of the first intermediate layer 1220 (e.g., the 1-1 functional layer 1221 and the first emission layer 1222) may be disposed on the side surface of the 1-2 portion AE1-2. Accordingly, the 1-2 portion AE1-2 may have a shape that appears to be drilled into the side surface of the first intermediate layer 1220.

[0223] The thickness t2 of the first intermediate layer 1220 may be greater than the thickness t1 of the 1-2 portion AE1-2, but the present disclosure is not necessarily limited thereto. In an embodiment, the thickness t2 of the first intermediate layer 1220 may be substantially equal to the thickness t1 of the 1-2 portion AE1-2, and the first intermediate layer 1220 may only cover the side surface of the 1-2 portion AE1-2.

[0224] It can be said that Figure 6 Region VIII of the embodiment shown in FIG. Fig. 8A However, the present disclosure is not necessarily limited thereto, and Figure 8B or Figure 8C The embodiments shown in the figure can also be applied to Figure 6 Region VIII of the embodiment illustrated in FIG. FIG. 8A to FIG. 8CThe described structure may be variously applied to the structure of portions adjacent to the auxiliary electrode and the first to third intermediate layers among various embodiments.

[0225] Fig. 9 is an enlarged schematic plan view illustrating a part of the display device according to the embodiment.

[0226] refer to Fig. 9 , the auxiliary electrode AE ​​may include 1-1 to 1-4 portions AE1-1, AE1-2, AE1-3, and AE1-4 surrounding the pixel area PA and a 2-1 portion AE2-1 extending to the pixel area PA. For example, the auxiliary electrode AE ​​may include a 2-1 portion AE2-1 extending in the ±y direction and vertically (or in the ±y direction) intersecting the pixel area PA.

[0227] The 2-1 portion AE2-1 of the auxiliary electrode AE ​​may divide the pixel area PA into a plurality of areas. For example, the 2-1 portion AE2-1 may divide the pixel area PA into a left side (or -x side) area in which the first subpixel SP1 and the second subpixel SP2 are arranged and a right side (or +x side) area in which the third subpixel SP3 is arranged. As an example, the 2-1 portion AE2-1 of the auxiliary electrode AE ​​may separate the first subpixel SP1 and the second subpixel SP2 from the third subpixel SP3 from each other.

[0228] The first to third counter electrodes 1230 , 2230 , and 3230 may extend in one direction or in different directions and may make contact with the auxiliary electrode AE.

[0229] The first pair of electrodes 1230 may be disposed on the first intermediate layer 1220 and may extend beyond the edge of the first intermediate layer 1220 in two different directions. For example, the first pair of electrodes 1230 may extend beyond the +y side edge of the first intermediate layer 1220 in the +y direction and may contact the 1-1 portion AE1-1 of the auxiliary electrode AE. At the same time, the first pair of electrodes 1230 may extend beyond the -x side edge of the first intermediate layer 1220 in the -x direction and may contact the 1-2 portion AE1-2 of the auxiliary electrode AE. The first pair of electrodes 1230 may overlap the 1-1 portion AE1-1 and the 1-2 portion AE1-2 at the same time. The regions where the first pair of electrodes 1230 overlap with the 1-1 portion AE1-1 and the 1-2 portion AE1-2 may extend in different directions. For example, the region where the first pair of electrodes 1230 overlaps with the 1-1 portion AE1-1 may have an elongated, substantially rectangular shape extending in the ±x direction. The region where the first pair of electrodes 1230 overlaps the 1-2 portion AE1-2 may have an elongated, substantially rectangular shape extending in the ±y directions. The two regions may be connected to each other and have a substantially L shape.

[0230] The second counter electrode 2230 may be disposed on the second intermediate layer 2220, may extend in the -y direction beyond the -y side edge of the second intermediate layer 2220, and may contact the 1-3 portion AE1-3 of the auxiliary electrode AE. The second counter electrode 2230 may overlap the 1-3 portion AE1-3 of the auxiliary electrode AE.

[0231] The third pair of electrodes 3230 may be disposed on the third intermediate layer 3220 and may extend beyond the edge of the third intermediate layer 3220 in two different directions. For example, the third pair of electrodes 3230 may extend beyond the +x side edge of the third intermediate layer 3220 in the +x direction and may contact the 1-4 portion AE1-4 of the auxiliary electrode AE. At the same time, the third pair of electrodes 3230 may extend beyond the -x side edge of the third intermediate layer 3220 in the -x direction and may contact the 2-1 portion AE2-1 of the auxiliary electrode AE. The third pair of electrodes 3230 may overlap the 1-4 portion AE1-4 and the 2-1 portion AE2-1 at the same time. The region where the third pair of electrodes 3230 overlaps the 1-4 portion AE1-4 and the 2-1 portion AE2-1 may have an elongated, substantially rectangular shape extending in the ±y direction. Regions of the third counter electrode 3230 overlapping the 1-4 portion AE1 - 4 and the 2-1 portion AE2 - 1 may be spaced apart from each other and may be located (or disposed) at opposite sides of the third counter electrode 3230 .

[0232] Similar to the 1-1 to 1-4 portions AE1-1, AE1-2, AE1-3, and AE1-4 of the auxiliary electrode AE, a voltage may also be applied to the 2-1 portion AE2-1. Therefore, the first pair of electrodes 1230 may receive the same voltage through the 1-1 portion AE1-1 and the 1-2 portion AE1-2, the second pair of electrodes 2230 may receive the same voltage through the 1-3 portion AE1-3, and the third pair of electrodes 3230 may receive the same voltage through the 1-4 portion AE1-4 and the 2-1 portion AE2-1.

[0237] The 2-1 portion AE2-1 of the auxiliary electrode may be disposed on the bank layer 111 between the first counter electrode 1230 and the third counter electrode 3230. Accordingly, it can be said that the 2-1 portion AE2-1 is disposed in the pixel area PA.

[0238] A portion of the third counter electrode 3230 may extend beyond the edge of the third intermediate layer 3220 and overlap the 2-1 portion AE2-1. In an embodiment, a portion (e.g., a portion on the -x side) opposite to the portion of the third counter electrode 3230 in contact with the 1-4 portion AE1-4 may extend beyond the -x side edge of the third intermediate layer 3220 in the -x direction and overlap the 2-1 portion AE2-1. The third counter electrode 3230 may be in direct contact with the 2-1 portion AE2-1.

[0243] The first pair of electrodes 1230 can be simultaneously connected to the 1-2 parts (see Fig.10 AE1-2) and the 1-1 part AE1-1 are in contact. Accordingly, the first pair of electrodes 1230 can be connected to the 1-2 part (see Fig.10 AE1-2) and part 1-1 AE1-1 to receive voltage.

[0244] Similar to Figure 7 In the embodiment illustrated in FIG. 2 , the second counter electrode 2230 may cover the second intermediate layer 2220 , may extend in the −y direction, and may contact the 1 - 3 portion AE1 - 3 .

[0272] The second pair of electrodes 2230 may be disposed on the second intermediate layer 2220 and may extend beyond the edge of the second intermediate layer 2220 in four different directions.

[0287] A portion of the first pair of electrodes 1230 may extend beyond the edge of the first intermediate layer 1220. For example, a portion of the first pair of electrodes 1230 may extend beyond the +y side edge of the first intermediate layer 1220 in the +y direction and overlap with the 1-1 portion AE1-1. The first pair of electrodes 1230 may be in direct contact with the 1-1 portion AE1-1. A portion of the opposite side of the first pair of electrodes 1230 may extend beyond the -y side edge of the first intermediate layer 1220 in the -y direction and overlap with the 2-2 portion AE2-2.

For example, a portion of the second pair of electrodes 2230 may be arranged on the side surface of the first pair of electrodes 1230. This is a characteristic due to the manufacturing process, and is a structure that may be generated in the case where the first intermediate layer 1220 and the first pair of electrodes 1230 are formed before the second intermediate layer 2220 and the second pair of electrodes 2230. In an embodiment, in the case where the second pair of electrodes 2230 is formed before the first pair of electrodes 1230, a portion of the first pair of electrodes 1230 may be arranged on the side surface of the second pair of electrodes 2230.

The first intermediate layer 1220 and the first counter electrode 1230 may be deposited by using the same mask M. In order to deposit different regions by using the same mask M, the process of depositing the first intermediate layer 1220 and the process of depositing the first counter electrode 1230 may be performed at different angles or by using different methods.

[0293] refer to Fig.18A , the first intermediate layer 1220 may be sprayed at a first deposition angle θ1 and deposited on the first subpixel electrode 1210 and the bank layer 111. When the first intermediate layer 1220 is deposited, the 1-1st functional layer 1221, the first emission layer 1222, and the 1-2nd functional layer 1223 may be sequentially deposited in this stated order.

[0294] Thereafter, the first pair of electrodes 1230 may be deposited to extend beyond the edge of the first intermediate layer 1220 while covering the first intermediate layer 1220 and contact the 1-2 portion AE1-2. The process of depositing the first pair of electrodes 1230 may include inclined deposition. For example, by spraying the deposition material at a second deposition angle θ2 that is inclined relative to the first deposition angle θ1 and has a different size from the first deposition angle θ1, the first pair of electrodes 1230 may be formed to extend beyond one edge of the first intermediate layer 1220 while covering the first intermediate layer 1220. At this time, the position and size of the second deposition angle θ2 may be appropriately adjusted so that a portion of the first pair of electrodes 1230 contacts the 1-2 portion AE1-2.

[0297] Thereafter, the first pair of electrodes 1230 may be deposited to contact the 1-2 portion AE1-2 and the 2-1 portion AE2-1 beyond the edge of the first intermediate layer 1220 while covering the first intermediate layer 1220. The deposition of the first pair of electrodes 1230 may be performed, for example, by spraying the deposition material at a second deposition angle θ2 greater than the first deposition angle θ1. As an example, the deposition of the first pair of electrodes 1230 may be performed by sputtering.

[0298] By following Fig.18A and Fig.18BIn the manufacturing process of the embodiment illustrated in FIG. 1 , the first pair of electrodes 1230 can be formed by using the same mask as the first intermediate layer 1220 without using a separate mask. The first pair of electrodes 1230 can be formed while changing the area. In the case where the position and size of the second deposition angle θ2 are appropriately adjusted, the extension of the first pair of electrodes 1230 beyond the edge of the first intermediate layer 1220 can be implemented as Figure 5 The extension in a single direction (e.g., -x direction) shown in FIG. Fig. 9 The extension in two intersecting directions (eg, -x direction and +y direction) shown in FIG. Fig.12 The extension in two directions (eg, ±x direction) as shown in FIG. Fig.15 The extension in four directions (eg, ±x directions and ±y directions) as shown in FIG.

[0299] exist Fig.18A and Fig.18B In the description, a description has been given based on the first counter electrode 1230 and the first intermediate layer 1220 , but the deposition method of the present disclosure may be equally applied to the second counter electrode 2230 and the third counter electrode 3230 and the second intermediate layer 2220 and the third intermediate layer 3220 .

[0300] According to the above-described embodiment, the metal layer (e.g., the counter electrode) which is the main reason for the decrease in transmittance does not overlap with the transmittance region, and therefore, the transmittance of the transmission region can be increased. The counter electrodes separated from each other in the pixel region can receive a common voltage through the auxiliary electrode. Since the auxiliary electrode does not overlap with the transmission region either, the transmittance of the transmission region can not be reduced.

The description of each feature or aspect within each embodiment should generally be considered applicable to other similar features or aspects in other embodiments. Although one or more embodiments have been described with reference to the accompanying drawings, it will be understood by those skilled in the art that various modifications in form and detail may be made therein without departing from the spirit and scope of the present disclosure as defined by the claims.
