[0055] Reference will now be made in more detail to embodiments, examples of which are shown in the accompanying drawings, wherein like reference numerals always refer to like elements. For this reason, the embodiments provided may have different forms and should not be construed as being limited to the descriptions set forth herein. Therefore, the embodiments will be described below solely by reference to the accompanying drawings to explain various aspects of this specification. As used herein, the term "and / or" includes any and all combinations of one or more of the relevant listed items. Throughout the 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.

[0056] One or more embodiments disclosed herein will be described in more detail below with reference to the accompanying drawings. Regardless of the figure number, the same or corresponding components are given the same reference numerals, and redundant descriptions are omitted.

[0057] It will be understood that although the terms "first," "second," etc. may be used herein to describe various components, these components should not be limited by these terms. These components are only used to distinguish one component from another.

[0058] 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.

[0059] It will also be understood that the term “comprise” and / or variations thereof used herein specify the presence of stated features or components, but does not preclude the presence or addition of one or more other features or components.

[0060] It will be understood that when a layer, region, or component is referred to as being "formed on" another layer, region, or component, the layer, region, or component may be directly or indirectly formed on the other layer, region, or component. In other words, intervening layers, regions, and / or components may be present, for example.

[0061] Furthermore, the use of “may” when describing embodiments of the present disclosure refers to “one or more embodiments of the present disclosure.”

[0062] As used herein, the phrase "plan view" may refer to viewing from the top or from a direction perpendicular to a display area of ​​a display device.

[0063] For ease of description, spatially relative terms such as “under,” “beneath,” “down,” “above,” “up,” “bottom,” “top,” etc. may be used herein to describe the relationship of one element or feature to another element or feature as shown in the accompanying drawings. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings.

It will also be understood that terms (such as those defined in common dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and / or this specification, and should not be interpreted in an idealized or overly formal sense unless explicitly defined as such herein.

[0069] Figure 1 is a schematic perspective view of a display device 1 according to the embodiment.

[0070] Reference Figure 1 The display device 1 includes a first display area DA1 in which an image is realized and a non-display area NDA in which no image is realized. The display device 1 can provide a main image by using light emitted from a plurality of main sub-pixels Pm arranged in the first display area DA1.

[0071] The display device 1 includes a second display area DA2. Components such as sensors using infrared light, visible light, or sound may be arranged in or below the second display area DA2, as will be described below with reference to Figure 2 The second display area DA2 may include a transmissive portion TA that transmits light and / or sound output from the component to the outside or traveling from the outside toward the component. In one or more embodiments, when light is transmitted through the second display area DA2, the light transmittance in the second display area DA2 may be approximately 30% or greater, for example, 50% or greater, 75% or greater, 80% or greater, 85% or greater, or 90% or greater.

[0072] According to this embodiment, the second display area DA2 may include an auxiliary light-emitting area Pg in which a plurality of auxiliary sub-pixels Pa are arranged, and light emitted from the plurality of auxiliary sub-pixels Pa may be used to provide a set or specific image. The image provided by the second display area DA2 is an auxiliary image and, therefore, may have a lower resolution than the image provided by the first display area DA1. In other words, because the second display area DA2 includes a transmissive portion TA capable of transmitting light and / or sound, the number of auxiliary sub-pixels Pa arranged per unit area may be less than the number of primary sub-pixels Pm arranged per unit area in the first display area DA1.

[0073] The second display area DA2 may be arranged on one side of the first display area DA1 or adjacent to one side of the first display area DA1. Figure 1 The second display area DA2 is shown to be arranged at the upper side of the first display area DA1, and thus, the second display area DA2 is arranged between the non-display area NDA and the first display area DA1. However, the disclosure is not limited thereto. The second display area DA2 may be arranged to be surrounded by the first display area DA1 (e.g., as shown in FIG. 1 ). Figure 3B ), and various modifications can be made in a suitable manner.

[0074] For example, despite Figure 1The second display area DA2 is shown as being arranged on the upper side of the first display area DA1 having a rectangular shape, but the disclosure is not limited thereto. The shape of the first display area DA1 may be circular, elliptical, or polygonal (such as a triangle or a pentagon), and the second display area DA2 may be arranged in the first display area DA1 (i.e., the second display area DA2 may be surrounded by the first display area DA1) and may have various suitable shapes.

[0075] Although an organic light emitting display device will now be shown and described as the display device 1, the display device 1 is not limited thereto. According to another embodiment, various suitable types of display devices such as an inorganic light emitting display device and a quantum dot light emitting display device may be used.

[0076] Figure 2 It is along Figure 1 Schematic cross-sectional view of the display device 1 according to the embodiment, taken along line AA′.

[0077] Reference Figure 2 The display device 1 may include a display panel 10 and a component 20 corresponding to the second display area DA2, wherein the display panel 10 includes a display element. In one or more embodiments, the component 20 may be in or below the second display area DA2.

[0078] The display panel 10 may include a substrate 100, a display element layer 200 disposed on the substrate 100 (for example, the display element layer 200 may be on the substrate 100 with an insulating layer IL′ between the display element layer 200 and the substrate 100), and a thin film encapsulation layer 300 as an encapsulation member that seals the display element layer 200. The display panel 10 may further include a lower protective film 175 disposed below the substrate 100.

[0079] The substrate 100 may include glass or a polymer resin. The polymer resin may include polyethersulfone, polyacrylate, polyetherimide, polyethylene naphthalate, polyethylene terephthalate, polyphenylene sulfide, polyarylate, polyimide, polycarbonate, cellulose acetate propionate, etc. The substrate 100 including the polymer resin may be flexible, rollable, and / or bendable. The substrate 100 may have a multilayer structure including a layer containing the aforementioned polymer resin and an inorganic layer.

[0080] The display element layer 200 may include a circuit layer including thin film transistors (eg, a first thin film transistor TFT and a second thin film transistor TFT′), display elements (eg, organic light emitting diodes OLED and OLED′), and an insulating layer IL (eg, an insulating layer IL) between the circuit layer and the display elements. Figure 2 ).

[0081] In the first display area DA1, a main subpixel Pm including a first thin film transistor TFT and an organic light emitting diode OLED connected to the first thin film transistor TFT may be arranged. In the second display area DA2, an auxiliary subpixel Pa including a second thin film transistor TFT' and an organic light emitting diode OLED' connected to the second thin film transistor TFT' may be arranged.

[0082] In the second display area DA2, a transmissive portion TA in which no pixels are arranged may be arranged. The transmissive portion TA may be understood as a transmissive area that transmits light / signals emitted by the component 20 or light / signals incident on the component 20. In one or more embodiments, the transmissive portion TA overlaps with a plurality of components 20 and does not include pixels. In one or more embodiments, the transmissive portion TA may be arranged to alternate with the auxiliary light emitting areas Pg. In other words, the transmissive portion TA may be arranged between auxiliary light emitting areas Pg adjacent to each other, and the auxiliary light emitting areas Pg may be arranged between the transmissive portions TA adjacent to each other (for example, as Figure 1 ).

[0083] The component 20 may be located in the second display area DA2 or below the second display area DA2. The component 20 may be an electronic component that uses light and / or sound. For example, the component 20 may be a sensor that receives and uses light (such as an infrared sensor), a sensor that outputs and senses light and / or sound to measure distance or identify fingerprints, etc., a small lamp that outputs light, a speaker that outputs sound, and / or a camera. Electronic components that use light may use light of various suitable wavelengths (such as visible light, infrared light, and / or ultraviolet light). In one or more embodiments, a plurality of components 20 may be arranged in the second display area DA2. For example, both the light-emitting device and the light-receiving device as the component 20 may be included in a single second display area DA2 or below a single second display area DA2. Alternatively, both the light-emitting portion and the light-receiving portion may be included in a single component (e.g., component 20).

[0084] The lower electrode layer BSM may be disposed in the second display area DA2. The lower electrode layer BSM may be disposed to correspond to the lower portion of the second thin-film transistor TFT'. In one or more embodiments, the second thin-film transistor TFT' may overlap the lower electrode layer BSM. The lower electrode layer BSM may block external light from reaching the auxiliary sub-pixel Pa including the second thin-film transistor TFT'. For example, the lower electrode layer BSM may block light emitted from the component 20 from reaching the auxiliary sub-pixel Pa.

[0085] In one or more embodiments, a constant voltage or signal may be applied to the lower electrode layer BSM to prevent or reduce damage to the pixel circuit due to electrostatic discharge.

[0086] The thin film encapsulation layer 300 may include at least one inorganic encapsulation layer and at least one organic encapsulation layer. Figure 2 A first inorganic encapsulating layer 310 and a second inorganic encapsulating layer 330 and an organic encapsulating layer 320 between the first inorganic encapsulating layer 310 and the second inorganic encapsulating layer 330 are shown.

[0087] Each of the first inorganic encapsulating layer 310 and the second inorganic encapsulating layer 330 may include one or more inorganic insulating materials (such as aluminum oxide, titanium oxide, tantalum oxide, hafnium oxide, zinc oxide, silicon oxide, silicon nitride and / or silicon oxynitride). The organic encapsulating layer 320 may include a polymer material. Examples of polymer materials may include acrylic resins, epoxy resins, polyimide, and polyethylene.

[0088] The lower protective film 175 may be attached to the lower surface of the substrate 100 and may support and protect the substrate 100. The lower protective film 175 may include an opening 175OP corresponding to the second display area DA2. The lower protective film 175 may improve the light transmittance of the second display area DA2 by including the opening 175OP. The lower protective film 175 may include polyethylene terephthalate (PET) and / or polyimide (PI).

[0089] The second display area DA2 may have an area larger than the area where the component 20 is arranged (for example, may have a planar area in the xy plane larger than the planar area in the xy plane where the component 20 is arranged). In one or more embodiments, the second display area DA2 may extend further than the component 20 in the x-direction and / or the y-direction. Therefore, the area of ​​the opening 175OP in the lower protective film 175 may be different from the area of ​​the second display area DA2. For example, the area of ​​the opening 175OP may be smaller than the area of ​​the second display area DA2.

[0090] In one or more embodiments, a plurality of components 20 may be arranged in the second display area DA2. The plurality of components 20 may have different suitable functions. For example, one of the plurality of components 20 may be a camera, and another may be an infrared sensor.

[0091] In one or more embodiments, one or more components such as an input sensing member for sensing a touch input, an anti-reflection member including a polarizer and a retarder or a color filter and a black matrix, and a transparent window may be arranged on the display panel 10 .

[0092] According to the present embodiment, the thin film encapsulation layer 300 is used as an encapsulation member for sealing the display element layer 200 , but the disclosure is not limited thereto. For example, an encapsulation substrate bonded to the substrate 100 by a sealant or glass frit may be used as a member for sealing the display element layer 200 .

[0093] Figure 3A and Figure 3B is a schematic plan view of a display panel 10 according to an embodiment.

[0094] Reference Figure 3A and Figure 3B The display panel 10 is arranged in the first display area DA1 and includes a plurality of master sub-pixels Pm. Each of the master sub-pixels Pm may include a display element such as an organic light emitting diode. Each master sub-pixel Pm may emit any one of red light, green light, blue light, and white light from the organic light emitting diode. The first display area DA1 may be Figure 2 The described packaging member is covered to be protected from external air or moisture.

[0095] The second display area DA2 may be arranged on one side of the first display area DA1 or adjacent to one side of the first display area DA1, and an auxiliary light emitting area Pg in which a plurality of auxiliary sub-pixels Pa are arranged is arranged in the second display area DA2. Each auxiliary sub-pixel Pa may include a display element such as an organic light emitting diode. Each auxiliary sub-pixel Pa may emit, for example, any one of red light, green light, blue light, and white light from the organic light emitting diode. In this case, at least two auxiliary sub-pixels (e.g., from Pa1, Pa2, and Pa3 (see FIG. 1 )) emitting light of the same color may be arranged on the second display area DA2. Figure 5 ) can be arranged in the auxiliary light emitting region Pg. The transmissive portion TA arranged between the auxiliary light emitting regions Pg can be arranged in the second display area DA2. At least one component 20 can be arranged to correspond to the lower portion (e.g., the lower portion in the thickness direction or the z-direction) of the second display area DA2 of the display panel 10.

[0096] In one or more embodiments, a primary subpixel Pm and an auxiliary subpixel Pa may include the same pixel circuit. However, the disclosure is not limited thereto. The pixel circuit in the primary subpixel Pm and the pixel circuit in the auxiliary subpixel Pa may be different from each other. Because the second display area DA2 includes the transmissive portion TA, the resolution of the second display area DA2 may be smaller than that of the first display area DA1.

[0097] Each of the main subpixel Pm and the auxiliary subpixel Pa can be connected (e.g., electrically connected) to an external circuit arranged in the non-display area NDA. In the non-display area NDA, a first scan driving circuit 110, a second scan driving circuit 120, a terminal 140, a first power line 160, and a second power line 170 can be arranged.

[0098] The first scan driving circuit 110 may provide a scan signal to each of the main sub-pixel Pm and the auxiliary sub-pixel Pa through a scan line SL. The first scan driving circuit 110 may provide a light emitting control signal to each sub-pixel through a light emitting control line EL. The second scan driving circuit 120 may be arranged in parallel with the first scan driving circuit 110, with the first display area DA1 and the second display area DA2 between the second scan driving circuit 120 and the first scan driving circuit 110. Some of the main sub-pixels Pm and the auxiliary sub-pixels Pa arranged in the first display area DA1 and the second display area DA2 may be connected (e.g., electrically connected) to the first scan driving circuit 110, and the other sub-pixels may be connected to the second scan driving circuit 120. In another embodiment, the second scan driving circuit 120 may be omitted.

[0099] The terminal 140 may be arranged on one side of the substrate 100 or adjacent to one side of the substrate 100. The terminal 140 may be exposed (i.e., the terminal may not be covered by the insulating layer) and connected (e.g., electrically connected) to the printed circuit board PCB. The terminal PCB-P of the printed circuit board PCB may be connected (e.g., electrically connected) to the terminal 140 of the display panel 10. The printed circuit board PCB transmits a signal or power of the controller to the display panel 10. The control signal generated by the controller may be transmitted to the first scan driving circuit 110 and the second scan driving circuit 120 through the printed circuit board PCB. The controller may provide a first power supply voltage ELVDD and a second power supply voltage ELVSS to the first power line 160 and the second power line 170 through a first connection line 161 and a second connection line 171, respectively (see Figure 4A , the second power voltage is also referred to as a common voltage). The first power voltage ELVDD may be supplied to each of the main subpixel Pm and the auxiliary subpixel Pa through the driving voltage line PL connected to the first power line 160, and the second power voltage ELVSS may be supplied to the counter electrode of each of the main subpixel Pm and the auxiliary subpixel Pa connected to the second power line 170.

[0100] The data driving circuit 150 is connected (e.g., electrically connected) to the data line DL. The data signal of the data driving circuit 150 can be provided to each of the main sub-pixel Pm and the auxiliary sub-pixel Pa through the connection line 151 connected to the terminal 140 and the data line DL connected to the connection line 151. Figure 3A The data driving circuit 150 is shown to be arranged on the printed circuit board PCB. However, in another embodiment, the data driving circuit 150 may be arranged on the substrate 100. For example, the data driving circuit 150 may be arranged on the substrate 100 and between the terminal 140 and the first power line 160.

[0101] The first power line 160 may include a first sub-line 162 and a second sub-line 163 extending in parallel (e.g., parallel to each other) along the x-direction, with the first display area DA1 between the first sub-line 162 and the second sub-line 163. The second power line 170 may partially surround the first display area DA1 in a ring shape having one open side (e.g., a side adjacent to the terminal 140).

[0102] exist Figure 3A , the second display area DA2 is shown as being arranged on one side of the first display area DA1 or adjacent to one side of the first display area DA1. However, the disclosure is not limited thereto. For example, Figure 3B As shown in , the second display area DA2 may be set to an area corresponding to the sensor arranged below the second display area DA2. In this case, the second display area DA2 may be arranged in the first display area DA1 (ie, the second display area DA2 may be surrounded by the first display area DA1).

The organic light emitting diode OLED can emit light with a set or specific brightness according to or based on the driving current.

[0108] Although Figure 4A FIG. 4 shows a case where the pixel circuit PC includes two thin film transistors and one storage capacitor, but the disclosure is not limited thereto. Figure 4B As shown in , the pixel circuit PC may include seven thin film transistors and one storage capacitor.

[0110] Although Figure 5 Each of the main sub-pixel Pm and the auxiliary sub-pixel Pa is connected to the signal lines SL, SL-1, EL, and DL, the initialization voltage line VL, and the driving voltage line PL, but the disclosure is not limited thereto. According to another embodiment, at least one of the signal lines SL, SL-1, EL, and DL, the initialization voltage line VL, and the driving voltage line PL may be shared by adjacent pixels.

[0112] The signal lines SL, SL-1, EL, and DL include a scan line SL that transmits a scan signal Sn, a previous scan line SL-1 that transmits a previous scan signal Sn-1 to a first initialization thin film transistor T4 and a second initialization thin film transistor T7, an emission control line EL that transmits an emission control signal En to an operation control thin film transistor T5 and an emission control thin film transistor T6, and a data line DL that crosses the scan line SL and transmits a data signal Dm.

[0113] The driving thin film transistor T1 includes a driving gate electrode G1 connected to the first electrode Cst1 of the storage capacitor Cst, a driving source electrode S1 connected to the driving voltage line PL via the operation control thin film transistor T5, and a driving drain electrode D1 connected (e.g., electrically connected) to the pixel electrode of the organic light emitting diode OLED via the light emission control thin film transistor T6.

[0115] The compensation thin film transistor T3 includes a compensation gate electrode G3 connected to the scan line SL, a compensation source electrode S3 connected to the driving drain electrode D1 of the driving thin film transistor T1 and further connected to the pixel electrode of the organic light emitting diode OLED via the light emission control thin film transistor T6, and a compensation drain electrode D3 connected to the first electrode Cst1 of the storage capacitor Cst, the first initialization drain electrode D4 of the first initialization thin film transistor T4, and the driving gate electrode G1 of the driving thin film transistor T1. The compensation thin film transistor T3 is turned on according to or based on the scan signal Sn received via the scan line SL, and connects (e.g., electrically connects) the driving gate electrode G1 and the driving drain electrode D1 of the driving thin film transistor T1 to each other, such that the driving thin film transistor T1 is diode-connected.

[0116] The first initialization thin film transistor T4 includes a first initialization gate electrode G4 connected to the previous scan line SL-1, a second initialization drain electrode D7 connected to the second initialization thin film transistor T7 and the initialization voltage line VL, and a first initialization drain electrode D4 connected to the first electrode Cst1 of the storage capacitor Cst, the compensation drain electrode D3 of the compensation thin film transistor T3, and the driving gate electrode G1 of the driving thin film transistor T1. The first initialization thin film transistor T4 is turned on according to or based on the previous scan signal Sn-1 received via the previous scan line SL-1, and is configured to transmit the initialization voltage Vint to the driving gate electrode G1 of the driving thin film transistor T1, thereby initializing the voltage of the driving gate electrode G1 of the driving thin film transistor T1.

[0117] The operation control thin film transistor T5 includes an operation control gate electrode G5 connected to the emission control line EL, an operation control source electrode S5 connected to the driving voltage line PL, and an operation control drain electrode D5 connected to the driving source electrode S1 of the driving thin film transistor T1 and the switching drain electrode D2 of the switching thin film transistor T2.

[0119] The operation control thin film transistor T5 and the light emission control thin film transistor T6 are concurrently (e.g., simultaneously) turned on according to or based on the light emission control signal En received via the light emission control line EL, and thus the driving voltage ELVDD is transmitted to the organic light emitting diode OLED, so that the driving current I OLED Can flow in organic light-emitting diodes (OLEDs).

[0120] The second initialization thin film transistor T7 includes a second initialization gate electrode G7 connected to the previous scan line SL-1, a second initialization source electrode S7 connected to the emission control drain electrode D6 of the emission control thin film transistor T6 and the pixel electrode of the organic light emitting diode OLED, and a second initialization drain electrode D7 connected to the first initialization source electrode S4 of the first initialization thin film transistor T4 and the initialization voltage line VL. The second initialization thin film transistor T7 is turned on according to or based on the previous scan signal Sn-1 received via the previous scan line SL-1, and initializes the pixel electrode of the organic light emitting diode OLED.

[0121] Although Figure 4B The first initialization thin film transistor T4 and the second initialization thin film transistor T7 are connected to the previous scan line SL-1, but the disclosure is not limited thereto.

[0122] The second electrode Cst2 of the storage capacitor Cst is connected to the driving voltage line PL, and the counter electrode of the organic light emitting diode OLED is connected to the common voltage ELVSS. Therefore, the organic light emitting diode OLED can receive the driving current I from the driving thin film transistor T1. OLEDAnd emits light, thereby displaying an image.

[0123] Although Figure 4B Each of the compensation thin film transistor T3 and the first initialization thin film transistor T4 has a double gate electrode, but each of the compensation thin film transistor T3 and the first initialization thin film transistor T4 may have a single gate electrode.

[0124] In this embodiment, the main sub-pixel Pm and the auxiliary sub-pixel Pa may include the same pixel circuit PC (for example, using the same pixel circuit configuration). However, the disclosure is not limited thereto. The main sub-pixel Pm and the auxiliary sub-pixel Pa may include pixel circuits having different suitable structures. For example, the main sub-pixel Pm may use Figure 4B The pixel circuit of the auxiliary sub-pixel Pa can be Figure 4A In one or more embodiments, the main sub-pixel Pm can be Figure 4A The pixel circuit of the auxiliary sub-pixel Pa can be Figure 4B pixel circuit.

[0125] Figure 5 is a schematic plan view of an arrangement of light emitting areas and transmissive areas of sub-pixels Pm and Pa arranged in the first display area DA1 and the second display area DA2, and Figure 6 It is along Figure 5 Schematic cross-sectional views of the display device taken along lines II' and II-II'.

[0126] Reference Figure 5 and Figure 6 , the main sub-pixels Pm1, Pm2 and Pm3 are arranged in the first display area DA1 of the display device according to the embodiment, and the auxiliary light emitting area Pg and the transmission portion TA including the auxiliary sub-pixels Pa1, Pa2 and Pa3 are arranged in the second display area DA2 of the display device.

[0127] In this embodiment, the primary subpixels Pm1, Pm2, and Pm3 arranged in the first display area DA1 and the auxiliary subpixels Pa1, Pa2, and Pa3 arranged in the second display area DA2 can have different pixel array structures. In this specification, the pixel arrangement structure is described based on the light-emitting area of ​​each subpixel. In this case, the light-emitting area of ​​the subpixel can be defined by the opening of the pixel-defining layer, which will be described in more detail below.

[0128] like Figure 5As shown in FIG, the main sub-pixels Pm1, Pm2, and Pm3 in the first display area DA1 can be arranged in a structure such as a Pentile structure. The first main sub-pixel Pm1, the second main sub-pixel Pm2, and the third main sub-pixel Pm3 can realize or provide different colors. For example, the first main sub-pixel Pm1, the second main sub-pixel Pm2, and the third main sub-pixel Pm3 can respectively realize red, green, and blue. In other words, the first main sub-pixel Pm1, the second main sub-pixel Pm2, and the third main sub-pixel Pm3 can respectively provide red light, green light, and blue light.

[0129] In one or more embodiments, a plurality of first main sub-pixels Pm1 and a plurality of third main sub-pixels Pm3 are alternately arranged in the first row 1N. A plurality of second main sub-pixels Pm2 may be arranged (e.g., repeatedly arranged) in an adjacent second row 2N (e.g., a second row 2N adjacent to the first row 1N) and may be spaced apart from each other at set or specific intervals. A plurality of third main sub-pixels Pm3 and a plurality of first main sub-pixels Pm1 may be alternately arranged in an adjacent third row 3N (e.g., a third row 3N adjacent to the second row 2N). A plurality of second main sub-pixels Pm2 may be arranged in an adjacent fourth row 4N (e.g., a fourth row 4N adjacent to the third row 3N) and may be spaced apart from each other at set or specific intervals. This arrangement of pixels may be repeated until the Nth row. Here, N represents a natural number greater than zero. In one or more embodiments, the area of ​​each of the third main sub-pixel Pm3 and the first main sub-pixel Pm1 may be larger than the area of ​​the second main sub-pixel Pm2 (e.g., in the example of FIG. 1 ). Figure 5 The area ratio of each of the third main sub-pixel Pm3 and the first main sub-pixel Pm1 in the plan view shown in FIG. Figure 5 The area of ​​the second main sub-pixel Pm2 in the plan view shown in FIG is large).

[0130] The plurality of first main sub-pixels Pm1 and the plurality of third main sub-pixels Pm3 arranged in the first row 1N are interleaved with the plurality of second main sub-pixels Pm2 arranged in the second row 2N. In other words, the plurality of first main sub-pixels Pm1 and the plurality of third main sub-pixels Pm3 arranged in the first row 1N may be offset from the plurality of second main sub-pixels Pm2 arranged in the second row 2N along the x-direction (i.e., not share a column with the plurality of second main sub-pixels Pm2 arranged in the second row 2N). Therefore, the first main sub-pixel Pm1 and the third main sub-pixel Pm3 are alternately arranged in the first column 1M, a plurality of second main sub-pixels Pm2 are arranged in the adjacent second column 2M (for example, the second column 2M adjacent to the first column 1M) and are spaced apart from each other at set or specific intervals, the third main sub-pixel Pm3 and the first main sub-pixel Pm1 are alternately arranged in the adjacent third column 3M (for example, the third column 3M adjacent to the second column 2M), and a plurality of second main sub-pixels Pm2 are arranged in the adjacent fourth column 4M (for example, the fourth column 4M adjacent to the third column 3M) ​​and are spaced apart from each other at set or specific intervals. This arrangement of pixels can be repeated up to the Mth column. Here, M represents a natural number greater than zero.

[0131] In one or more embodiments, the first main sub-pixel Pm1 is arranged at each of the first and third vertices facing each other among the vertices of the virtual quadrilateral VS, the center point of the second main sub-pixel Pm2 is at the center point of the virtual quadrilateral VS, and the third main sub-pixel Pm3 is arranged at each of the second and fourth vertices that are the remaining vertices. The second main sub-pixel Pm2 can be at the center point between the first main sub-pixels Pm1 arranged at each of the first and third vertices, and at the center point between the third main sub-pixels Pm3 arranged at each of the second and fourth vertices. In one or more embodiments, the virtual quadrilateral VS can be modified in various ways as appropriate. For example, the virtual quadrilateral VS can be a rectangle, a rhombus, or a square.

[0132] Such a pixel arrangement structure may be a matrix structure (eg, a Pentile matrix structure), and in this case, high resolution may be achieved with a small number of pixels by using a rendering driving scheme that shares adjacent pixels to represent colors.

[0133] The auxiliary sub-pixels Pa1, Pa2 and Pa3 in the second display area DA2 can be arranged similarly to the main sub-pixels Pm1, Pm2 and Pm3. That is, the auxiliary sub-pixels Pa1, Pa2 and Pa3 can be arranged as an RGBG structure (for example, an RGBGPentile structure). The first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2 and the third auxiliary sub-pixel Pa3 can realize or provide different colors. For example, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2 and the third auxiliary sub-pixel Pa3 can realize red, green and blue, respectively. In other words, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2 and the third auxiliary sub-pixel Pa3 can provide red light, green light and blue light, respectively. In one or more embodiments, compared to the main sub-pixel, two or more auxiliary sub-pixels emitting light of the same color can be arranged in the center of the auxiliary light-emitting area Pg.

[0134] The first auxiliary subpixel Pa1 and the third auxiliary subpixel Pa3 may be sequentially arranged in the first column 1I, and the third auxiliary subpixel Pa3 and the first auxiliary subpixel Pa1 may be sequentially arranged in the adjacent second column 2I. In this case, the first auxiliary subpixel Pa1 and the third auxiliary subpixel Pa3 may be arranged to face each other in the first column 1I and the second column 2I. In other words, the first auxiliary subpixel Pa1 in the first column 1I corresponds to the third auxiliary subpixel Pa3 in the second column 2I, and the third auxiliary subpixel Pa3 in the first column 1I corresponds to the first auxiliary subpixel Pa1 in the second column 2I.

[0135] A plurality of second auxiliary subpixels Pa2 may be arranged between adjacent first and third auxiliary subpixels Pa1 and Pa3 (e.g., the first auxiliary subpixel Pa1 in the first column 1I and the third auxiliary subpixel Pa3 in the second column 2I). The plurality of second auxiliary subpixels Pa2 may be spaced apart from one another. Furthermore, at least two of the plurality of second auxiliary subpixels Pa2 may share at least one auxiliary intermediate layer. In this case, one first auxiliary subpixel Pa1, one third auxiliary subpixel Pa3, and two second auxiliary subpixels Pa2 may form a group and be repeatedly arranged in the auxiliary light-emitting region Pg.

[0136] In one or more embodiments, the second auxiliary intermediate layers of two adjacent second auxiliary sub-pixels Pa2 may be arranged in the first area AR1. In this case, as will be described below Figure 9 As shown in the figure, in the first area AR1, the second auxiliary intermediate layer arranged on the second auxiliary pixel electrode of each of the second auxiliary sub-pixels Pa2 adjacent to each other can be arranged on the pixel defining layer 119 arranged between the second auxiliary pixel electrodes adjacent to each other, and thus can be formed integrally.

[0137] In one or more embodiments, the planar area of ​​the first area AR1 may be different from the planar area of ​​the second auxiliary sub-pixel Pa2. For example, the planar area of ​​the first area AR1 may be larger than the planar area of ​​the second auxiliary sub-pixel Pa2. In one or more embodiments, the sum of the planar areas of all the second auxiliary sub-pixels Pa2 arranged in the first area AR1 may be smaller than the planar area of ​​the first area AR1.

[0138] In this case, the first shortest distance d1 between adjacent second auxiliary sub-pixels Pa2 can be reduced. That is, typically, when forming sub-pixels, an intermediate layer can be formed on the pixel electrode by evaporating a deposition material and depositing the deposition material through a mask assembly. In this case, due to assembly tolerances during the manufacture of the mask assembly, deformation of the mask assembly during the deposition process, etc., the intermediate layer cannot be formed according to the designed pattern. Therefore, a set or specific spacing is required between adjacent pixel electrodes. In this case, a set or specific distance must exist between auxiliary sub-pixels that realize or provide the same color. However, when the spacing between the auxiliary sub-pixels is too large, the size of the auxiliary light-emitting area Pg increases, and thus the area of ​​the transmissive portion TA decreases, thereby reducing the transmittance of the second display area DA2. However, when auxiliary sub-pixels emitting light of different colors are not arranged between auxiliary sub-pixels that realize or provide the same color, as described above, the shortest distance between adjacent auxiliary sub-pixels can be reduced by sharing at least one intermediate layer.

[0139] That is, generally, when forming pixel electrodes, the pixel electrodes can be patterned by photoresist. In this case, the distance between adjacent pixel electrodes can be precisely adjusted. However, as described above, when at least one intermediate layer is formed on a plurality of pixel electrodes by a deposition process, a set or specific spacing may be required between the pixel electrodes in order to arrange the intermediate layer throughout all pixel electrodes.

[0140] However, in one or more disclosed embodiments, the distance between auxiliary sub-pixels implementing or providing the same color may be reduced by placing the auxiliary sub-pixels implementing or providing the same color adjacent to each other and sharing at least one auxiliary intermediate layer.

[0141] The first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2 and the third auxiliary sub-pixel Pa3 may form an auxiliary light emitting region Pg. Figure 5 In the embodiment, although eight auxiliary sub-pixels Pa1, Pa2, and Pa3 are included in one auxiliary light emitting region Pg, the number and arrangement of the auxiliary sub-pixels Pa1, Pa2, and Pa3 in one auxiliary light emitting region Pg may be variously modified in an appropriate manner.

[0142] Because no display elements are arranged in the transmissive portion TA, the transmissive portion TA is a region with high light transmittance. In one or more embodiments, multiple transmissive portions TA may be provided in the second display area DA2. The transmissive portions TA may be arranged alternately with the auxiliary light-emitting regions Pg along the first direction (i.e., the x-direction) and / or the second direction (i.e., the y-direction). Alternatively, the transmissive portions TA may be arranged to surround the auxiliary light-emitting regions Pg.

[0143] In the second display area DA2, the radical units U in which the auxiliary light emitting area Pg and the transmissive portion TA are bound may be repeatedly arranged in the x-direction and the y-direction.

[0144] exist Figure 5 In the embodiment, the base unit U may have a rectangular shape in which one auxiliary light-emitting region Pg and three transmissive portions TA arranged around the auxiliary light-emitting region Pg are bundled. The base unit U is obtained by dividing the second display area DA2 into repeated shapes, without indicating a break in the structure of the second display area DA2. For example, in one or more embodiments, the transmissive portion TA in one base unit U may be integrally formed with the transmissive portion TA in the base unit U adjacent to the one base unit U.

[0145] In one or more embodiments, in the base unit U, the area of ​​the auxiliary light-emitting region Pg may be smaller than the area of ​​the transmissive portion TA. For example, the area of ​​the auxiliary light-emitting region Pg may be approximately one-third of the area of ​​the transmissive portion TA. In other words, the area of ​​the auxiliary light-emitting region Pg may be approximately one-quarter of the area of ​​the base unit U, and the area of ​​the transmissive portion TA may be approximately three-quarters of the area of ​​the base unit U.

[0146] A corresponding unit U' having an area equal to or substantially equal to that of the basic unit U may be set in the first display area DA1. In this case, the number of the main sub-pixels Pm1, Pm2, and Pm3 in the corresponding unit U' may be greater than the number of the auxiliary sub-pixels Pa1, Pa2, and Pa3 in the basic unit U.

[0147] Reference Figure 6 , the third main subpixel Pm3 is arranged in the first display area DA1, and the third auxiliary subpixel Pa3 and the transmissive portion TA are arranged in the second display area DA2. In this case, the third main subpixel Pm3 and the third auxiliary subpixel Pa3 can be subpixels that emit light of the same color. In one or more embodiments, the third main subpixel Pm3 and the third auxiliary subpixel Pa3 can realize a blue color. In other words, the third main subpixel Pm3 and the third auxiliary subpixel Pa3 can provide blue light.

[0148] The main subpixel Pm may include a first thin film transistor TFT, a main storage capacitor Cst, and a main organic light emitting diode OLED. The auxiliary subpixel Pa may include a second thin film transistor TFT', an auxiliary storage capacitor Cst', and an auxiliary organic light emitting diode OLED'. The transmissive portion TA may include an opening area TAH corresponding to the transmissive portion TA.

[0149] The component 20 may be arranged below the second display area DA2. The component 20 may be a camera that captures images or an infrared (IR) sensor that transmits or receives infrared light. Because the transmissive portion TA is arranged in the second display area DA2, light emitted to or received from the component 20 may be transmitted. For example, light emitted from the component 20 may pass through the transmissive portion TA and travel in the z direction (e.g., pass through the transmissive portion TA and away from the component 20), and light generated from outside the display device and incident on the component 20 may pass through the transmissive portion TA and travel in the -z direction (e.g., pass through the transmissive portion TA and toward the component 20). In one or more embodiments, the component 20 may include a plurality of image sensors, and one image sensor may be arranged to correspond to one transmissive portion TA.

[0150] Hereinafter, a structure in which components in a display device according to an embodiment are stacked will be described.

The substrate 100 may have a multilayer structure including a layer including the aforementioned polymer resin and an inorganic layer.

[0152] The buffer layer 111 may be located on the substrate 100 and reduce or block the infiltration of foreign matter, moisture, or external air from below the substrate 100, and may provide a flat surface on the substrate 100. The buffer layer 111 may include an inorganic material (e.g., oxide or nitride), an organic material, or an organic and inorganic compound, and may be formed as a single layer or multiple layers of inorganic and organic materials. A barrier layer may be between the substrate 100 and the buffer layer 111 to prevent or reduce the infiltration of ambient air. In one or more embodiments, the buffer layer 111 may include silicon oxide (SiO2) and / or silicon nitride (SiN x ). The buffer layer 111 may be provided such that a first buffer layer 111 a and a second buffer layer 111 b are stacked.

[0153] In the second display area DA2, the lower electrode layer BSM may be disposed between the first buffer layer 111a and the second buffer layer 111b. In another embodiment, the lower electrode layer BSM may be disposed between the substrate 100 and the first buffer layer 111a. The lower electrode layer BSM may be disposed under the second thin film transistor TFT' and prevent or reduce degradation of the characteristics of the second thin film transistor TFT' due to light emitted from the assembly 20.

[0154] In addition, the lower electrode layer BSM can be connected to the wiring GCL arranged on another layer through a contact hole. The lower electrode layer BSM receives a constant voltage or signal from the wiring GCL. For example, the lower electrode layer BSM can receive a driving voltage ELVDD or a scan signal. The lower electrode layer BSM can significantly reduce the possibility of generating electrostatic discharge in response to receiving a constant voltage or signal. The lower electrode layer BSM may include aluminum (Al), platinum (Pt), palladium (Pd), silver (Ag), magnesium (Mg), gold (Au), nickel (Ni), neodymium (Nd), iridium (Ir), chromium (Cr), calcium (Ca), molybdenum (Mo), titanium (Ti), tungsten (W) and / or copper (Cu). The lower electrode layer BSM may include a single layer or multiple layers of the above materials.

[0155] A first thin-film transistor (TFT) and a second thin-film transistor (TFT') may be disposed on the buffer layer 111. The first thin-film transistor (TFT) includes a first semiconductor layer (A1), a first gate electrode (G1), a first source electrode (S1), and a first drain electrode (D1). The second thin-film transistor (TFT') includes a second semiconductor layer (A2), a second gate electrode (G2), a second source electrode (S2), and a second drain electrode (D2). The first thin-film transistor (TFT) may be connected to the main organic light-emitting diode (OLED) in the first display area (DA1) to drive the main organic light-emitting diode (OLED). The second thin-film transistor (TFT') may be connected to the auxiliary organic light-emitting diode (OLED') in the second display area (DA2) to drive the auxiliary organic light-emitting diode (OLED').

[0156] The first semiconductor layer A1 and the second semiconductor layer A2 are arranged on the buffer layer 111 and may include polycrystalline silicon. In another embodiment, the first semiconductor layer A1 and the second semiconductor layer A2 may each include amorphous silicon. In another embodiment, the first semiconductor layer A1 and the second semiconductor layer A2 may each include an oxide of at least one material selected from the group consisting of indium (In), gallium (Ga), tin (Sn), zirconium (Zr), vanadium (V), hafnium (Hf), cadmium (Cd), germanium (Ge), chromium (Cr), titanium (Ti), and zinc (Zn). The first semiconductor layer A1 and the second semiconductor layer A2 may each include a channel region and a source region and a drain region doped with impurities.

[0157] The second semiconductor layer A2 may overlap with the bottom electrode layer BSM, with the second buffer layer 111b being disposed between the second semiconductor layer A2 and the bottom electrode layer BSM. In an embodiment, the width of the second semiconductor layer A2 may be smaller than the width of the bottom electrode layer BSM. Therefore, when projected perpendicularly to the substrate 100, the second semiconductor layer A2 may overlap with the bottom electrode layer BSM in its entirety. In other words, when viewed from a plan view, the second semiconductor layer A2 may overlap with the bottom electrode layer BSM in its entirety.

[0158] The first gate insulating layer 112 may be provided to cover the first semiconductor layer A1 and the second semiconductor layer A2. The first gate insulating layer 112 may include an inorganic insulating material such as silicon oxide (SiO2), silicon nitride (SiN x ), silicon oxynitride (SiON), aluminum oxide (Al2O3), titanium oxide (TiO2), tantalum oxide (Ta2O5), hafnium oxide (HfO2), or zinc oxide (ZnO2). The first gate insulating layer 112 may include a single layer or multiple layers including the above inorganic insulating materials.

[0159] The first gate electrode G1 and the second gate electrode G2 are arranged on the first gate insulating layer 112 to overlap the first semiconductor layer A1 and the second semiconductor layer A2, respectively. Each of the first gate electrode G1 and the second gate electrode G2 may include Mo, Al, Cu, Ti, etc. and may include a single layer or multiple layers. For example, the first gate electrode G1 and the second gate electrode G2 may each include a single layer of Mo.

[0160] The second gate insulating layer 113 may be provided to cover the first gate electrode G1 and the second gate electrode G2. The second gate insulating layer 113 may include an inorganic insulating material (such as SiO2, SiN x , SiON, Al 2 O 3 , TiO 2 , Ta 2 O 5 , HfO 2 or ZnO 2 ). The second gate insulating layer 113 may include a single layer or multiple layers including the above inorganic insulating materials.

[0161] A first upper electrode CE2 of the main storage capacitor Cst and a second upper electrode CE2 ′ of the auxiliary storage capacitor Cst′ may be disposed on the second gate insulating layer 113 .

[0162] In the first display area DA1, the first upper electrode CE2 may overlap the first gate electrode G1 thereunder. The first gate electrode G1 and the first upper electrode CE2 overlapping each other with the second gate insulating layer 113 therebetween may form a main storage capacitor Cst. The first gate electrode G1 may be the first lower electrode CE1 of the main storage capacitor Cst.

[0163] In the second display area DA2, the second upper electrode CE2' may overlap the second gate electrode G2 thereunder. The second gate electrode G2 and the second upper electrode CE2' overlapping each other with the second gate insulating layer 113 therebetween may form an auxiliary storage capacitor Cst'. The first gate electrode G1 may be a second lower electrode CE1' of the auxiliary storage capacitor Cst'.

[0164] Each of the first and second upper electrodes CE2 and CE2' may include Al, Pt, Pd, Ag, Mg, Au, Ni, Nd, Ir, Cr, Li, Ca, Mo, Ti, W, and / or Cu, and may include a single layer or multiple layers of the above materials.

[0165] The interlayer insulating layer 115 may be formed to cover the first upper electrode CE2 and the second upper electrode CE2'. The interlayer insulating layer 115 may include SiO2, SiN x , SiON, Al2O3, TiO2, Ta2O5, HfO2 or ZnO2.

[0166] When the first gate insulating layer 112, the second gate insulating layer 113, and the interlayer insulating layer 115 are collectively referred to as the inorganic insulating layer IL, the structure in which the inorganic insulating layer IL is stacked on the substrate 100 may have a transmittance of about 90% or more with respect to infrared wavelengths. For example, light having a wavelength of about 900 nm to about 1100 nm passing through the substrate 100 and the inorganic insulating layer IL may have a transmittance of about 90%.

[0167] The first source electrode S1 and the second source electrode S2 and the first drain electrode D1 and the second drain electrode D2 are arranged on the interlayer insulating layer 115. The first source electrode S1 and the second source electrode S2 and the first drain electrode D1 and the second drain electrode D2 may each include a conductive material including Mo, Al, Cu, Ti, etc. and may be formed as a single layer or multiple layers including the conductive material. For example, the first source electrode S1 and the second source electrode S2 and the first drain electrode D1 and the second drain electrode D2 may each have a multilayer structure of Ti / Al / Ti.

[0168] The planarization layer 117 may be disposed to cover the first and second source electrodes S1 and S2 and the first and second drain electrodes D1 and D2. The planarization layer 117 may have a flat upper surface so that the main pixel electrode 221 and the auxiliary pixel electrode 221' disposed thereon are formed to be flat.

[0169] The planarization layer 117 may be formed as a single layer or multiple layers of an organic material. The planarization layer 117 may include commercial polymers such as benzocyclobutene (BCB), polyimide, hexamethyldisiloxane (HMDSO), polymethylmethacrylate (PMMA), or polystyrene (PS), polymer derivatives having phenolic groups, acryl-based polymers, imide-based polymers, acryl ether-based polymers, amide-based polymers, fluorine-based polymers, paraxylene-based polymers, vinyl alcohol-based polymers, and / or blends thereof.

[0170] The planarization layer 117 has an opening exposing one of the first source electrode S1 and the first drain electrode D1 of the first thin film transistor TFT, and the main pixel electrode 221 may contact the first source electrode S1 or the first drain electrode D1 through the opening and be connected (eg, electrically connected) to the first thin film transistor TFT.

[0171] In addition, the planarization layer 117 has an opening exposing one of the second source electrode S2 and the second drain electrode D2 of the second thin film transistor TFT′, and the auxiliary pixel electrode 221′ can contact the second source electrode S2 or the second drain electrode D2 through the opening and be connected (e.g., electrically connected) to the second thin film transistor TFT′.

[0172] The main pixel electrode 221 and the auxiliary pixel electrode 221' may each include a conductive oxide (such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium oxide (In2O3), indium gallium oxide (IGO) and / or aluminum zinc oxide (AZO)). In another embodiment, the main pixel electrode 221 and the auxiliary pixel electrode 221' may each include a reflective layer comprising Ag, Mg, Al, Pt, Pd, Au, Ni, Nd, Ir, Cr or a compound thereof. In another embodiment, the main pixel electrode 221 and the auxiliary pixel electrode 221' may each further include a layer comprising ITO, IZO, ZnO or In2O3 above or below the reflective layer. In one or more embodiments, the main pixel electrode 221 and the auxiliary pixel electrode 221' may each have a stacked structure of ITO / Ag / ITO.

[0173] The pixel-defining layer 119 may cover the edges of each of the primary pixel electrode 221 and the auxiliary pixel electrode 221′. The pixel-defining layer 119 overlaps each of the primary pixel electrode 221 and the auxiliary pixel electrode 221′ (e.g., partially overlaps the edge of each of the primary pixel electrode 221 and the auxiliary pixel electrode 221′ along the z-direction) and includes a first opening OP1 and a second opening OP2, which define the light-emitting area of ​​the sub-pixel. The pixel-defining layer 119 increases the distance between the edges of the primary pixel electrode 221 and the auxiliary pixel electrode 221′ and the counter electrode 223 on the primary pixel electrode 221 and the auxiliary pixel electrode 221′, thereby preventing or substantially preventing arcing in or at the edges of the primary pixel electrode 221 and the auxiliary pixel electrode 221′. The pixel-defining layer 119 may include an organic insulating material (such as polyimide, polyamide, acrylic resin, BCB, HMDSO, or phenolic resin) and may be formed by spin coating, etc.

[0174] When the planarization layer 117 and the pixel defining layer 119 are collectively referred to as an organic insulating layer OL, the organic insulating layer OL may have a transmittance of about 90% or more with respect to infrared wavelengths. For example, light having a wavelength of about 900 nm to about 1100 nm passing through the organic insulating layer OL may have a transmittance of about 90%.

[0175] The main intermediate layer and the auxiliary intermediate layer arranged to correspond to the main pixel electrode 221 and the auxiliary pixel electrode 221' may be included in the first opening OP1 and the second opening OP2 of the pixel defining layer 119. In this case, the main intermediate layer includes a main emission layer 222b, and the auxiliary intermediate layer is provided with an auxiliary emission layer 222b'. Each of the main emission layer 222b and the auxiliary emission layer 222b' may include a polymer material or a low-molecular material and may emit red light, green light, blue light, or white light.

[0176] The main intermediate layer and / or the auxiliary intermediate layer may include an organic functional layer 222e arranged above and / or below the main emission layer 222b and the auxiliary emission layer 222b'. The organic functional layer 222e may include a first functional layer 222a and / or a second functional layer 222c. The first functional layer 222a or the second functional layer 222c may be omitted.

[0177] The first functional layer 222a may be disposed below the main emission layer 222b and the auxiliary emission layer 222b'. In this case, in an embodiment, the first functional layer 222a may be patterned to correspond to the transmissive portion TA and, like the main emission layer 222b and the auxiliary emission layer 222b', may be patterned to correspond to the first and second openings OP1 and OP2, and may be disposed within the first and second openings OP1 and OP2 and the transmissive portion TA. In another embodiment, the first functional layer 222a may be disposed to completely cover the first and second display areas DA1 and DA2. In another embodiment, the first functional layer 222a may be patterned to correspond to the first and second openings OP1 and OP2, and may be disposed within the first and second openings OP1 and OP2 without being disposed within the transmissive portion TA. In another embodiment, the first functional layer 222a may be disposed to completely cover the first display area DA1 and cover the second display area DA2 excluding the transmissive portion TA. Below, for ease of description, the case where the first functional layer 222a is disposed to completely cover the first and second display areas DA1 and DA2 will be described in more detail.

[0178] The first functional layer 222a may include a single layer or multiple layers containing organic materials. The first functional layer 222a may be a hole transport layer (HTL) having a single layer structure. Alternatively, the first functional layer 222a may include a hole injection layer (HIL) and the HTL. The first functional layer 222a may be integrally formed to correspond to the main sub-pixel Pm and the auxiliary sub-pixel Pa included in the first display area DA1 and the second display area DA2, respectively. Therefore, the first functional layer 222a may correspond to the transmissive portion TA.

[0179] The second functional layer 222c may be arranged on the main emission layer 222b and the auxiliary emission layer 222b'. In this case, in an embodiment, the second functional layer 222c may be patterned to correspond to the transmissive portion TA and, like the main emission layer 222b and the auxiliary emission layer 222b', may be patterned to correspond to the first and second openings OP1 and OP2, and may be arranged in the first and second openings OP1 and OP2 and the transmissive portion TA. In another embodiment, the second functional layer 222c may be arranged to completely cover the first and second display areas DA1 and DA2. In another embodiment, the second functional layer 222c may be patterned to correspond to the first and second openings OP1 and OP2, and may be arranged in the first and second openings OP1 and OP2 without being arranged in the transmissive portion TA. In other words, the second functional layer 222c may be arranged in the first and second openings OP1 and OP2 but not in the opening area TAH corresponding to the transmissive portion TA. In another embodiment, the second functional layer 222c may be arranged to completely cover the first display area DA1 and cover the second display area DA2 except the transmissive portion TA (e.g., the open area TAH corresponding to the transmissive portion TA). Hereinafter, for convenience of description, the case where the second functional layer 222c is arranged to completely cover the first display area DA1 and the second display area DA2 will be described in more detail.

[0180] The second functional layer 222c may include a single layer or multiple layers containing organic materials. The second functional layer 222c may include an electron transport layer (ETL) and / or an electron injection layer (EIL). The second functional layer 222c may be integrally formed to correspond to the main sub-pixel Pm and the auxiliary sub-pixel Pa included in the first display area DA1 and the second display area DA2, respectively. Therefore, the second functional layer 222c may correspond to the transmissive portion TA.

[0181] The counter electrode 223 is arranged on the second functional layer 222c. The counter electrode 223 may include a conductive material having a low work function. For example, the counter electrode 223 may include a (semi-) transparent layer containing Ag, Mg, Al, Pt, Pd, Au, Ni, Nd, Ir, Cr, Li, Ca or an alloy thereof. Alternatively, the counter electrode 223 may also include a layer containing ITO, IZO, ZnO or In2O3 on the (semi-) transparent layer including the above materials. The counter electrode 223 may be formed integrally to correspond to the main sub-pixel Pm and the auxiliary sub-pixel Pa respectively included in the first display area DA1 and the second display area DA2.

[0182] The layers formed from the main pixel electrode 221 to the opposite electrode 223 in the first display area DA1 may form a main organic light emitting diode OLED. The layers formed from the auxiliary pixel electrode 221 ′ to the opposite electrode 223 in the second display area DA2 may form an auxiliary organic light emitting diode OLED′.

[0183] An upper layer 250 including an organic material may be formed on the counter electrode 223. The upper layer 250 may be a layer provided to protect the counter electrode 223 and to increase light extraction efficiency. The upper layer 250 may include an organic material having a refractive index higher than that of the counter electrode 223. Alternatively, the upper layer 250 may be provided by stacking layers having different refractive indices. For example, the upper layer 250 may be provided by sequentially stacking a high refractive index layer, a low refractive index layer, and a high refractive index layer. In this case, the refractive index of the high refractive index layer may be 1.7 or greater, and the refractive index of the low refractive index layer may be 1.3 or less.

[0184] The upper layer 250 may further include LiF. Alternatively, the upper layer 250 may further include SiO2 or SiN x Inorganic insulating materials.

[0185] In this embodiment, the first functional layer 222a, the second functional layer 222c, the counter electrode 223, and the upper layer 250 may include an opening area TAH corresponding to the transmissive portion TA. That is, the first functional layer 222a, the second functional layer 222c, the counter electrode 223, and the upper layer 250 may each have an opening corresponding to the transmissive portion TA. The openings in the first functional layer 222a, the second functional layer 222c, the counter electrode 223, and the upper layer 250 may be formed by laser. In one or more embodiments, the widths of the openings forming the opening area TAH may be substantially the same. For example, the width of the opening of the counter electrode 223 may be substantially the same as the width of the opening area TAH.

[0186] In addition, in the present embodiment, the first functional layer 222a, the second functional layer 222c, and the upper layer 250 may be omitted. In this case, the opening of the counter electrode 223 may be the opening area TAH.

[0187] As used herein, the opening area TAH corresponding to the transmission part TA may refer to an embodiment in which the opening area TAH overlaps the transmission part TA. In this case, the area of ​​the opening area TAH may be smaller than the area of ​​the first hole H1 formed in the inorganic insulating layer IL. For this reason, Figure 6 The width Wt of the opening area TAH is smaller than the width W1 of the first hole H1, which may be smaller than the width W2 of the second hole H2. Here, the area of ​​the opening area TAH and the area of ​​the first hole H1 may be defined as the area of ​​the narrowest portion of the opening.

[0188] In one or more embodiments, the first functional layer 222a, the second functional layer 222c, the counter electrode 223, and the upper layer 250 may be arranged on the side surfaces of the first hole H1, the second hole H2, and the third hole H3. In one or more embodiments, the slope of the side surfaces of the first hole H1, the second hole H2, and the third hole H3 relative to the upper surface of the substrate 100 may be gentler than the slope of the side surfaces of the opening area TAH relative to the upper surface of the substrate 100.

[0189] As used herein, the formation of the open area TAH refers to an embodiment in which members such as the opposing electrode 223 are removed from the transmission portion TA, and thus light transmittance of the transmission portion TA may be significantly increased.

[0190] The main organic light emitting diode OLED and the auxiliary organic light emitting diode OLED′ may be sealed by a thin film encapsulation layer 300. The thin film encapsulation layer 300 may be disposed on the upper layer 250. The thin film encapsulation layer 300 may prevent or substantially prevent external moisture or foreign substances from penetrating into the main organic light emitting diode OLED and the auxiliary organic light emitting diode OLED′.

[0191] The thin film encapsulation layer 300 may include at least one inorganic encapsulation layer and at least one organic encapsulation layer. Figure 6 A structure is shown in which the thin film encapsulation layer 300 includes a first inorganic encapsulation layer 310, an organic encapsulation layer 320, and a second inorganic encapsulation layer 330 stacked sequentially. In another embodiment, the number of organic encapsulation layers, the number of inorganic encapsulation layers, and the stacking order may be appropriately changed.

[0192] Each of the first inorganic encapsulating layer 310 and the second inorganic encapsulating layer 330 may include one or more inorganic insulating materials (such as aluminum oxide, titanium oxide, tantalum oxide, hafnium oxide, zinc oxide, silicon oxide, silicon nitride and / or silicon oxynitride) and may be formed by chemical vapor deposition (CVD). The organic encapsulating layer 320 may include a polymer material. Examples of polymer materials may include silicone resins, acrylic resins, epoxy resins, polyimide, and polyethylene.

[0193] The first inorganic encapsulation layer 310, the organic encapsulation layer 320, and the second inorganic encapsulation layer 330 may be integrally formed to cover the display area (corresponding to the auxiliary light emitting area Pg of the second display area DA2 and the first display area DA1) and the sensor area (corresponding to the transmissive portion TA). Therefore, the first inorganic encapsulation layer 310, the organic encapsulation layer 320, and the second inorganic encapsulation layer 330 may be arranged in the opening area TAH.

[0194] In another embodiment, the organic encapsulating layer 320 may be integrally formed to cover the second display area DA2, but may not be in the transmissive portion TA. In other words, the organic encapsulating layer 320 may include an opening corresponding to the transmissive portion TA. In this case, the first inorganic encapsulating layer 310 and the second inorganic encapsulating layer 330 may contact each other within the opening area TAH.

[0195] In this embodiment, the size of the second opening OP2 defining the light emitting area EA2 of the third auxiliary subpixel Pa3 may be larger than the size of the first opening OP1 defining the light emitting area EA1 of the third main subpixel Pm3. Therefore, when the same or substantially the same current is supplied to the third auxiliary subpixel Pa3 and the third main subpixel Pm3, the brightness of the third auxiliary subpixel Pa3 may be greater than the brightness of the third main subpixel Pm3.

[0196] In the second display area DA2, the number of auxiliary subpixels in each basic unit U is smaller than the number of main subpixels in the corresponding unit U', and generally, the brightness achieved in the corresponding unit U' in the first display area DA1 and the brightness achieved in the basic unit U in the second display area DA2 can be the same or substantially the same. Therefore, in one or more embodiments, the brightness of the third auxiliary subpixel Pa3 can be greater than the brightness of the third main subpixel Pm3, and the brightness achieved in the corresponding unit U' in the first display area DA1 and the brightness achieved in the basic unit U in the second display area DA2 can be the same or substantially the same.

[0197] Figure 7 is a schematic cross-sectional view of a display device according to an embodiment. Figure 7 In, with Figure 6 The same reference numerals as those in the drawings denote the same components, and repeated descriptions thereof are omitted.

[0198] Reference Figure 7 The display device includes a first display area DA1 and a second display area DA2. A main subpixel Pm is arranged in the first display area DA1, and an auxiliary light-emitting area including an auxiliary subpixel Pa and a transmissive portion TA are arranged in the second display area DA2. The light-emitting area EA2 of the auxiliary subpixel Pa is larger than the light-emitting area EA1 of the main subpixel Pm. In addition, in the display device according to the embodiment, the pixel arrangement structure of the main subpixel Pm is different from the pixel arrangement structure of the auxiliary subpixel Pa.

[0199] In this embodiment, at least one of the first and second functional layers 222a and 222c and the upper layer 250 may be disposed to correspond to the transmissive portion TA. That is, at least one of the first and second functional layers 222a and 222c and the upper layer 250 may be disposed in the open area TAH.

[0200] The opposing electrode 223 has an opening corresponding to the transmissive portion TA, and a width of the opening may be substantially equal to a width of the opening area TAH. In this case, the opposing electrode 223 may be formed using a mask provided with a capping layer covering the transmissive portion TA.

[0201] In another embodiment, after forming the opposing electrode 223 on the entire surface of the substrate 100 , an opening may be formed in the opposing electrode 223 by removing a portion of the opposing electrode 223 corresponding to the transmission portion TA using a laser.

[0202] Figure 8 is a schematic cross-sectional view of a display device according to an embodiment. Figure 8 In, with Figure 6 The same reference numerals as those in the drawings denote the same components, and repeated descriptions thereof are omitted.

[0203] Reference Figure 8 The display device includes a first display area DA1 in which a main subpixel Pm is arranged, and a second display area DA2 in which an auxiliary subpixel Pa and a transmissive portion TA are arranged. The emission area EA2 of the auxiliary subpixel Pa is larger than the emission area EA1 of the main subpixel Pm. In addition, in the display device according to the embodiment, the pixel arrangement structure of the main subpixel Pm is different from the pixel arrangement structure of the auxiliary subpixel Pa.

[0204] In this embodiment, the main organic light-emitting diode OLED and the auxiliary organic light-emitting diode OLED' may be covered by an encapsulation substrate 300'. The encapsulation substrate 300' comprises a transparent material. For example, the encapsulation substrate 300' may comprise a glass material. Alternatively, the encapsulation substrate 300' may comprise a polymer resin, etc. The encapsulation substrate 300' may prevent or substantially prevent external moisture or foreign matter from penetrating into the main organic light-emitting diode OLED and the auxiliary organic light-emitting diode OLED'.

[0205] A sealing material such as a sealant may be disposed between the substrate 100 on which the main organic light emitting diode OLED and the auxiliary organic light emitting diode OLED' are formed and the encapsulation substrate 300'. The sealing material may block or substantially block external moisture or foreign matter that may penetrate between the substrate 100 and the encapsulation substrate 300'.

[0206] Figure 9 It is along Figure 5 Schematic cross-sectional view of the display device taken along line III-III'.

[0207] Reference Figure 9At least two of the plurality of auxiliary sub-pixels arranged in the auxiliary light-emitting region may emit light of the same color. For example, at least two first auxiliary sub-pixels, at least two second auxiliary sub-pixels Pa2, and / or at least two third auxiliary sub-pixels may be arranged in the auxiliary light-emitting region.

[0208] In this case, when there is no auxiliary sub-pixel emitting light of a color different from the same color between the auxiliary sub-pixels emitting light of the same color and adjacent to each other among the plurality of auxiliary sub-pixels, the auxiliary sub-pixels emitting light of the same color and adjacent to each other can share at least one intermediate layer. In other words, when two adjacent auxiliary sub-pixels emit light of the same color and the auxiliary sub-pixel emitting light of a different color is not located between the two adjacent auxiliary sub-pixels, the two adjacent auxiliary sub-pixels can share at least one intermediate layer with each other. Specifically, when the auxiliary sub-pixel emitting light of a color different from the same color is not arranged between the auxiliary sub-pixels emitting light of the same color and adjacent to each other, the auxiliary sub-pixels emitting light of the same color and adjacent to each other can share an organic functional layer and / or an auxiliary emission layer. Hereinafter, for ease of description, the case where each auxiliary sub-pixel sharing at least one auxiliary intermediate layer is the second auxiliary sub-pixel Pa2 will be described in more detail below. In addition, the case where the at least one second auxiliary intermediate layer shared by the second auxiliary sub-pixel Pa2 is the second auxiliary emission layer 222b'-2 will be described in more detail below.

[0209] For example, Figure 5 As shown in , when the first auxiliary sub-pixel Pa1 and / or the third auxiliary sub-pixel Pa3 are not arranged between the second auxiliary sub-pixels Pa2 adjacent to each other, the second auxiliary sub-pixels Pa2 adjacent to each other can share the second auxiliary emission layer 222b'-2 with each other. In this case, the second auxiliary emission layer 222b'-2 shared by the adjacent second auxiliary sub-pixels Pa2 can be disconnected and not shared by the first auxiliary sub-pixel Pa1, the third auxiliary sub-pixel Pa3 and the main sub-pixel. That is, based on Figure 9 The second auxiliary sub-pixels Pa2 adjacent to each other may share the second auxiliary emission layer 222b'-2, and the first auxiliary sub-pixel Pa1, the third auxiliary sub-pixel Pa3, and the main sub-pixel do not share the second auxiliary emission layer 222b'-2.

[0210] In this case, as described above, the second auxiliary emission layer 222b'-2 can be integrally formed on the second auxiliary pixel electrode 221'-2 of one of the second auxiliary sub-pixels Pa2 adjacent to each other, the pixel defining layer 119 arranged between the second auxiliary pixel electrodes 221'-2 of the second auxiliary sub-pixels Pa2 adjacent to each other, and the second auxiliary pixel electrode 221'-2 of another of the second auxiliary sub-pixels Pa2 adjacent to each other.

[0211] In this case, even if the second auxiliary emission layer 222b'-2 is deposited on the substrate 100 by evaporation (or vaporization), the second auxiliary emission layer 222b'-2 will not be individually deposited in a pattern form on the second auxiliary pixel electrodes 221'-2 spaced apart from each other, and therefore, the interval between the adjacent second auxiliary pixel electrodes 221'-2 can be reduced.

[0212] In general, one second auxiliary emission layer can be arranged to correspond to one second auxiliary pixel electrode and spaced apart from the one second auxiliary pixel electrode. In this case, in order to arrange each second auxiliary emission layer to correspond to each second auxiliary pixel electrode, adjacent second auxiliary pixel electrodes must be sufficiently spaced apart from each other. In this case, because adjacent second auxiliary pixel electrodes must be spaced apart from each other by a minimum distance, there is a limit on reducing the size of the auxiliary light-emitting area.

[0213] However, in one or more disclosed embodiments, as the shortest distance between mutually adjacent second auxiliary pixel electrodes 221'-2 decreases, the shortest distance between the light-emitting regions of the second auxiliary sub-pixels Pa2 defined by the opening of the pixel defining layer 119 may decrease. In this case, the shortest distance between the second auxiliary pixel electrodes 221'-2 is the shortest distance between mutually adjacent portions of the second auxiliary pixel electrodes 221'-2 that face each other.

[0214] Figure 10 is a schematic plan view of an arrangement of auxiliary sub-pixels Pa1 , Pa2 , and Pa3 disposed in a second display area according to another embodiment.

[0215] Reference Figure 10 ,and Figure 5 The second display area corresponding to the second display area DA2 in FIG may include an auxiliary light emitting area Pg and a transmissive portion TA. The auxiliary light emitting area Pg and the transmissive portion TA may be similar to Figure 5 The auxiliary light emitting region Pg and the transmissive portion TA are shown in FIG.

[0216] A plurality of auxiliary sub-pixels Pa1, Pa2, and Pa3 may be arranged in the auxiliary light emitting region Pg. The plurality of auxiliary sub-pixels Pa1, Pa2, and Pa3 may include a first auxiliary sub-pixel Pa1, a second auxiliary sub-pixel Pa2, and a third auxiliary sub-pixel Pa3. The first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may realize or provide different colors. For example, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may realize red, green, and blue, respectively. In other words, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may provide red light, green light, and blue light, respectively. A plurality of first auxiliary sub-pixels Pa1 and a plurality of third auxiliary sub-pixels Pa3 may be provided. The plurality of first auxiliary sub-pixels Pa1 and the plurality of third auxiliary sub-pixels Pa3 may be arranged along a first direction (for example, Figure 10 Furthermore, at least one of the plurality of first auxiliary sub-pixels Pa1 and at least one of the plurality of third auxiliary sub-pixels Pa3 may be arranged along the second direction (eg, Figure 10 In this case, the plurality of second auxiliary sub-pixels Pa2 may be arranged between the plurality of first auxiliary sub-pixels Pa1 and the plurality of third auxiliary sub-pixels Pa3 (e.g., arranged between the plurality of first auxiliary sub-pixels Pa1 and the plurality of third auxiliary sub-pixels Pa3 along the x-direction and / or the y-direction).

[0217] The plurality of second auxiliary subpixels Pa2 may share a second auxiliary intermediate layer. That is, the integrally formed second auxiliary intermediate layer may be arranged on the second auxiliary pixel electrodes of the second auxiliary subpixels Pa2 that are spaced apart from each other. The second auxiliary intermediate layer may be arranged on the plurality of second auxiliary subpixels Pa2 in the second area AR2. In this case, the plurality of second auxiliary subpixels Pa2 may be arranged in the second area AR2.

[0218] In this case, the first shortest distance d1 between the second auxiliary sub-pixels Pa2 arranged along the first direction and adjacent to each other can be reduced as described above. In addition, because the at least one second auxiliary intermediate layer does not need to be patterned to correspond to each second auxiliary sub-pixel Pa2 respectively, the second shortest distance d2 between the second auxiliary sub-pixels Pa2 arranged along the second direction and adjacent to each other can be reduced. In this case, the first shortest distance d1 and the second shortest distance d2 can be smaller than the shortest distance between the second auxiliary sub-pixel Pa2 and the first auxiliary sub-pixel Pa1 and the shortest distance between the second auxiliary sub-pixel Pa2 and the third auxiliary sub-pixel Pa3. In this case, the shortest distance can be the shortest distance among the straight-line distances from the outer side of one of the auxiliary sub-pixels adjacent to each other to the outer side of the other auxiliary sub-pixels adjacent to each other.

[0219] Figure 11 is a schematic plan view of an arrangement of auxiliary sub-pixels Pa1 , Pa2 , and Pa3 disposed in a second display area according to another embodiment.

[0220] Reference Figure 11 ,and Figure 5 The second display area corresponding to the second display area DA2 in FIG may include an auxiliary light emitting area Pg and a transmissive portion TA. The auxiliary light emitting area Pg and the transmissive portion TA may be similar to Figure 5 The auxiliary light emitting region Pg and the transmissive portion TA are shown in FIG.

[0221] A plurality of auxiliary sub-pixels Pa1, Pa2, and Pa3 may be arranged in the auxiliary light emitting region Pg. The plurality of auxiliary sub-pixels Pa1, Pa2, and Pa3 may include a first auxiliary sub-pixel Pa1, a second auxiliary sub-pixel Pa2, and a third auxiliary sub-pixel Pa3. The first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may realize or provide different colors. For example, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may realize red, green, and blue, respectively. In other words, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may provide red light, green light, and blue light, respectively.

[0222] In this case, the plurality of third auxiliary sub-pixels Pa3 may be arranged along the first direction (eg, Figure 11 In addition, some of the plurality of first auxiliary sub-pixels Pa1 and some of the plurality of third auxiliary sub-pixels Pa3 may be arranged in a line along the second direction (e.g., Figure 11 For example, based on Figure 11 , one first auxiliary sub-pixel Pa1 and one third auxiliary sub-pixel Pa3 may be arranged in a line along the second direction. In this case, a plurality of second auxiliary sub-pixels Pa2 may be arranged between mutually adjacent first auxiliary sub-pixels Pa1 and between mutually adjacent third auxiliary sub-pixels Pa3. In one or more embodiments, two second auxiliary sub-pixels Pa2 may be arranged in a line along the first direction between two third auxiliary sub-pixels Pa3 arranged in a line along the first direction.

[0223] In this case, the plurality of second auxiliary sub-pixels Pa2 adjacent to each other may share at least one second auxiliary intermediate layer. Specifically, the plurality of second auxiliary sub-pixels Pa2 adjacent to each other may share the second auxiliary emission layer arranged in the entire first area AR1. In this case, the second auxiliary emission layer may completely block the first area AR1.

[0224] Figure 12 is a schematic plan view of an arrangement of auxiliary sub-pixels Pa1 , Pa2 , and Pa3 disposed in a second display area according to another embodiment.

[0225] Reference Figure 12 ,and Figure 5 The second display area corresponding to the second display area DA2 in FIG may include an auxiliary light emitting area Pg and a transmissive portion TA. The auxiliary light emitting area Pg and the transmissive portion TA may be similar to Figure 5 The auxiliary light emitting region Pg and the transmissive portion TA are shown in FIG.

[0226] A plurality of auxiliary sub-pixels Pa1, Pa2, and Pa3 may be arranged in the auxiliary light emitting region Pg. The plurality of auxiliary sub-pixels Pa1, Pa2, and Pa3 may include a first auxiliary sub-pixel Pa1, a second auxiliary sub-pixel Pa2, and a third auxiliary sub-pixel Pa3. The first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may realize or provide different colors. For example, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may realize red, green, and blue, respectively. In other words, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may provide red light, green light, and blue light, respectively.

[0227] The first auxiliary sub-pixel Pa1 and the third auxiliary sub-pixel Pa3 may be Figure 11 The plurality of second auxiliary sub-pixels Pa2 may be arranged in the same manner as shown in FIG. The plurality of second auxiliary sub-pixels Pa2 may be arranged between the first auxiliary sub-pixel Pa1 and the third auxiliary sub-pixel Pa3. In this case, the first auxiliary sub-pixel Pa1 and the third auxiliary sub-pixel Pa3 may be arranged to surround the plurality of second auxiliary sub-pixels Pa2. In this case, the plurality of second auxiliary sub-pixels Pa2 may be arranged in the middle of the auxiliary light emitting region Pg.

[0228] Along a first direction (eg, Figure 12 A plurality of first auxiliary sub-pixels Pa1 arranged in a line along the first direction (eg, the x direction in the middle) may share at least one first auxiliary intermediate layer. Figure 12 The plurality of third auxiliary sub-pixels Pa3 arranged in a line (in the x-direction in the image) may share at least one third auxiliary intermediate layer. The plurality of second auxiliary sub-pixels Pa2 may share at least one second auxiliary intermediate layer. In one or more embodiments, the plurality of second auxiliary sub-pixels Pa2 are not arranged in a line including the plurality of first auxiliary sub-pixels Pa1 or a line including the plurality of third auxiliary sub-pixels Pa3.

[0229] In this case, at least one third auxiliary intermediate layer may be disposed throughout the third area AR3 to include a plurality of third auxiliary subpixels Pa3. At least one first auxiliary intermediate layer may be disposed throughout the fourth area AR4 to include a plurality of first auxiliary subpixels Pa1.

[0230] In addition, at least one second auxiliary intermediate layer may be disposed in the entire second area AR2 to include a plurality of second auxiliary sub-pixels Pa2.

[0231] In this case, the shortest distance between the first auxiliary sub-pixels Pa1, the first shortest distance and the second shortest distance between the second auxiliary sub-pixels Pa2, and the shortest distance between the third auxiliary sub-pixels Pa3 adjacent to each other can be reduced, and thus the area occupied by the auxiliary sub-pixels Pa1, Pa2, and Pa3 in the auxiliary light-emitting region Pg can be reduced. In this case, by reducing the area of ​​the auxiliary light-emitting region Pg, the area occupied by the transmissive portion TA in the basic unit can be increased.

[0232] Therefore, in the display device, the transmittance of the second display area can be improved by ensuring the area of ​​the transmissive portion TA to be as large as possible.

[0233] Figure 13 is a schematic plan view of an arrangement of auxiliary sub-pixels Pa1 , Pa2 , and Pa3 disposed in a second display area according to another embodiment.

[0234] Reference Figure 13 ,and Figure 5 The second display area corresponding to the second display area DA2 in FIG may include an auxiliary light emitting area Pg and a transmissive portion TA. The auxiliary light emitting area Pg and the transmissive portion TA may be similar to Figure 5 The auxiliary light emitting region Pg and the transmissive portion TA are shown in FIG.

[0235] A plurality of auxiliary sub-pixels Pa1, Pa2, and Pa3 may be arranged in the auxiliary light-emitting region Pg. The plurality of auxiliary sub-pixels Pa1, Pa2, and Pa3 may include a first auxiliary sub-pixel Pa1, a second auxiliary sub-pixel Pa2, and a third auxiliary sub-pixel Pa3. The first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may realize or provide different colors. For example, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may realize red, green, and blue, respectively. In other words, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may provide red light, green light, and blue light, respectively. In this case, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may each have a rectangular shape and may be arranged in a pentile shape.

[0236] In this case, the first auxiliary sub-pixel Pa1 and the third auxiliary sub-pixel Pa3 may be arranged along a first direction (eg, Figure 13 x direction in the ) and a second direction (e.g., Figure 13 In this case, the first auxiliary sub-pixel Pa1 and the third auxiliary sub-pixel Pa3 may each have a stripe shape. In one or more embodiments, the first auxiliary sub-pixel Pa1 and the third auxiliary sub-pixel Pa3 may be arranged in a line along the second direction.

[0237] At least two of the plurality of second auxiliary sub-pixels Pa2 may be arranged adjacent to or facing side surfaces of the first auxiliary sub-pixel Pa1 and the third auxiliary sub-pixel Pa3 arranged along the second direction. In this case, at least two of the plurality of second auxiliary sub-pixels Pa2 may be arranged in a line along the second direction.

[0238] The plurality of second auxiliary sub-pixels Pa2 arranged in a line may share at least one second auxiliary intermediate layer. In this case, at least one second auxiliary intermediate layer located in the plurality of second auxiliary sub-pixels Pa2 arranged in a line may not be arranged on the first auxiliary sub-pixel Pa1, the third auxiliary sub-pixel Pa3 and / or the main sub-pixel.

[0239] In this case, the shortest distance between adjacent second auxiliary sub-pixels Pa2 can be reduced. Specifically, since it is not necessary to arrange at least one second auxiliary intermediate layer spaced apart from each other in the spaced-apart second auxiliary sub-pixels Pa2, the spacing distance between the second auxiliary sub-pixels Pa2 can be reduced. Therefore, in the display device, the transmission area of ​​the second display region can be maximized or increased by maximizing or increasing the area of ​​the transmission portion TA.

The first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may realize or provide different colors. For example, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may realize red, green, and blue, respectively. In other words, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may provide red light, green light, and blue light, respectively. In this case, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may each have a rectangular shape and may be arranged in a Pentile shape. In this case, the first auxiliary sub-pixel Pa1 and the third auxiliary sub-pixel Pa3 may be arranged in a rectangular shape with the same Figure 13 Arranged in the same manner as shown.

[0243] The plurality of second auxiliary sub-pixels Pa2 may be arranged between the first auxiliary sub-pixel Pa1 and the third auxiliary sub-pixel Pa3 (eg, between the first auxiliary sub-pixel Pa1 and the third auxiliary sub-pixel Pa3). Figure 14 In one or more embodiments, the first auxiliary subpixel Pa1 and the third auxiliary subpixel Pa3 may be arranged to surround the plurality of second auxiliary subpixels Pa2.

[0244] The plurality of second auxiliary sub-pixels Pa2 arranged in the auxiliary light-emitting region Pg may share at least one second auxiliary intermediate layer. Specifically, the plurality of second auxiliary sub-pixels Pa2 may share one second auxiliary emission layer. In this case, the light-emitting regions of the plurality of second auxiliary sub-pixels Pa2 may be arranged in the second region AR2, where the second auxiliary emission layer is arranged on a plane. In this case, the second auxiliary emission layer may be arranged on the second auxiliary pixel electrode of each second auxiliary sub-pixel Pa2.

[0245] In this case, the intervals between the second auxiliary sub-pixels Pa2 spaced apart from each other can be reduced. In this case, compared with separately forming the second auxiliary emission layers spaced apart from each other to correspond to each second auxiliary sub-pixel Pa2, by reducing the area of ​​the auxiliary light emitting region Pg, the area of ​​the transmission portion TA can be increased, thereby increasing the transmittance of the second display area.

For example, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may realize red, green, and blue, respectively. In other words, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may provide red light, green light, and blue light, respectively. In this case, the first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2, and the third auxiliary sub-pixel Pa3 may each have a rectangular shape and may be arranged in a Pentile shape. In this case, the second auxiliary sub-pixel Pa2 may be arranged in a rectangular shape with the same color as the first auxiliary sub-pixel Pa1. Figure 13 Arranged in the same manner as shown.

Some of the plurality of first auxiliary sub-pixels Pa1 and some of the plurality of third auxiliary sub-pixels Pa3 may be arranged in a line along the second direction (e.g., Figure 15 y direction in the figure) are arranged into lines.

[0250] In this case, some of the plurality of second auxiliary sub-pixels Pa2 arranged in a line along the second direction may share at least one second auxiliary intermediate layer arranged in the fifth area AR5. Because the distance between the second auxiliary pixel electrodes can be adjusted or reduced, the distance between the plurality of second auxiliary sub-pixels Pa2 sharing at least one second auxiliary intermediate layer can be reduced (for example, to increase the area of ​​the transmissive portion TA).

[0254] In this case, the plurality of second auxiliary subpixels Pa2 may share at least one second auxiliary intermediate layer. In this case, at least one second auxiliary intermediate layer may be disposed in the second area AR2, and the light emitting area of ​​each second auxiliary subpixel Pa2 may be disposed in the second area AR2.

[0255] In this case, the adjacent second auxiliary subpixels Pa2 can be designed as close as possible, thereby reducing the size of the auxiliary light emitting region Pg. In addition, since the area of ​​the transmission portion TA can be ensured to be as large as possible, the transmittance of the second display area can be increased.

[0260] In this case, the plurality of third auxiliary subpixels Pa3 may share at least one third auxiliary intermediate layer disposed in the third area AR3. In this case, the light emitting area of ​​each third auxiliary subpixel Pa3 may be disposed in the third area AR3.

[0261] The plurality of first auxiliary sub-pixels Pa1 may share at least one first auxiliary intermediate layer disposed in the fourth area AR4. In this case, the light emitting area of ​​each first auxiliary sub-pixel Pa1 may be disposed in the fourth area AR4.

[0262] In this case, as the adjacent first auxiliary subpixels Pa1 share one auxiliary intermediate layer, the adjacent second auxiliary subpixels Pa2 share one auxiliary intermediate layer, and the adjacent third auxiliary subpixels Pa3 share one auxiliary intermediate layer, the distance between the auxiliary subpixels can be reduced.

One third auxiliary sub-pixel Pa3 can be set to correspond to one first auxiliary sub-pixel Pa1 and one second auxiliary sub-pixel Pa2, and the size of the third auxiliary sub-pixel Pa3 can be larger than the size of the first auxiliary sub-pixel Pa1 and the second auxiliary sub-pixel Pa2. That is, the first auxiliary sub-pixel Pa1 and the second auxiliary sub-pixel Pa2 can be arranged to be long along the x-direction, and the third auxiliary sub-pixel Pa3 can be arranged to be long along the y-direction. Therefore, the length of the third auxiliary sub-pixel Pa3 along the y-direction can be equal to or greater than the sum of the length of the first auxiliary sub-pixel Pa1 along the y-direction and the length of the second auxiliary sub-pixel Pa2 along the y-direction. Such a pixel arrangement structure is called an S-bar structure.

[0291] The first auxiliary sub-pixel Pa1, the second auxiliary sub-pixel Pa2 and the third auxiliary sub-pixel Pa3 may form an auxiliary light emitting region Pg. Figure 5 In FIG. 1 , one auxiliary light emitting region Pg includes eight auxiliary sub-pixels Pa1, Pa2, and Pa3. However, the number and arrangement of the auxiliary sub-pixels Pa1, Pa2, and Pa3 included in one auxiliary light emitting region Pg may be variously modified in an appropriate manner.

[0292] In this case, the second auxiliary subpixels Pa2 adjacent to each other may be disposed between the first auxiliary subpixels Pa1 spaced apart from each other. In this case, the second auxiliary subpixels Pa2 adjacent to each other may share at least one second auxiliary intermediate layer disposed in the fifth area AR5.

[0293] In addition, the third auxiliary sub-pixels Pa3 adjacent to each other may share at least one third auxiliary intermediate layer disposed in the third area AR3.

[0294] Therefore, in the display device, the size of the auxiliary light emitting region Pg may be reduced, and thus the transmittance of the second display region may be improved.

[0295] Figure 23 is a schematic plan view of an arrangement of sub-pixels Pm1, Pm2, and Pm3, and Pa1, Pa2, and Pa3 disposed in the first and second display areas DA1 and DA2 according to another embodiment.

[0296] Reference Figure 23 , the main sub-pixels Pm1 , Pm2 , and Pm3 arranged in the first display area DA1 and the auxiliary sub-pixels Pa1 , Pa2 , and Pa3 arranged in the second display area DA2 may have different pixel arrangement structures.

[0297] In this embodiment, the first main sub-pixel Pm1 and the first auxiliary sub-pixel Pa1 can realize red, the second main sub-pixel Pm2 and the second auxiliary sub-pixel Pa2 can realize green, and the third main sub-pixel Pm3 and the third auxiliary sub-pixel Pa3 can realize blue. In other words, the first main sub-pixel Pm1 and the first auxiliary sub-pixel Pa1 can provide red light, the second main sub-pixel Pm2 and the second auxiliary sub-pixel Pa2 can provide green light, and the third main sub-pixel Pm3 and the third auxiliary sub-pixel Pa3 can provide blue light.

[0298] In this embodiment, the third primary subpixel Pm3 that realizes a blue color (or provides blue light) in the first display area DA1 is arranged in odd-numbered rows (e.g., the first row 1N). However, the third auxiliary subpixel Pa3 that realizes a blue color in the second display area DA2 is arranged in even-numbered rows (e.g., the second row 2N). This arrangement is referred to as an RGBG matrix structure (e.g., an RGBGPentile matrix structure).

[0299] The second main sub-pixel Pm2 that realizes green (or provides green light) in the first display area DA1 is arranged in an even row (such as the second row 2N). However, the second auxiliary sub-pixel Pa2 that realizes green in the second display area DA2 is arranged in an odd row (such as the first row 1N). This arrangement is called an RBGB matrix structure (for example, an RBGB Pentile matrix structure). That is, the position of the blue sub-pixel and the position of the green sub-pixel are reversed in the first display area DA1 and the second display area DA2. In this case, the first auxiliary sub-pixels Pa1 adjacent to each other can share the first auxiliary emission layer in the fourth area AR4, and the second auxiliary sub-pixels Pa2 adjacent to each other can share the second auxiliary emission layer in the fifth area AR5. The third auxiliary sub-pixels Pa3 adjacent to each other can share the third auxiliary emission layer in the third area AR3.

[0300] In this case, since the interval between the auxiliary sub-pixels emitting light of the same color and adjacent to each other may be reduced, the area of ​​the auxiliary light emitting region Pg may be reduced and the area of ​​the transmissive portion TA may be increased.

[0301] Therefore, the transmittance of the display device may be improved, thereby preventing or substantially preventing malfunction of components arranged in the second display area DA2.

[0302] Figure 24 is a cross-sectional view of an apparatus 400 for manufacturing a display device according to an embodiment. Figure 25 Is shown by Figure 24 4 is a cross-sectional view of a method of manufacturing a second main emission layer and a second auxiliary emission layer of a display device using an apparatus 400 shown in FIG.

[0303] Reference Figure 24 and Figure 25 , a display device can be manufactured by the apparatus 400 for manufacturing a display device.

[0304] The apparatus 400 may include a chamber 410 , a mask assembly 420 , a first support 430 , a second support 440 , a deposition source 450 , a magnetic force generator 460 , a vision unit 470 , and a pressure regulator 480 .

[0305] The chamber 410 may have a space formed therein, and a portion of the chamber 410 may be formed to have an opening. A gate valve 411 may be disposed in the opening of the chamber 410 to be opened or closed.

[0306] The mask assembly 420 may be arranged in the chamber 410. The mask assembly 420 may include a mask frame 421 and a mask sheet 422. The mask frame 421 may be formed by connecting a plurality of frames to each other and may include an opening therein. In this case, the mask frame 421 may include one opening or a plurality of openings that are separated or spaced apart from each other. In this case, the mask frame 421 may have a lattice shape (e.g., a window frame).

[0307] The mask sheet 422 may extend over the mask frame 421 and be fixed to the mask frame 421. The mask sheet 422 may have an opening through which the deposition material passes. One mask sheet 422 or multiple mask sheets 422 may be included. When one mask sheet 422 is included, the mask sheet 422 may be arranged on the mask frame 421 and may block the opening of the mask frame 421. According to another embodiment, when multiple mask sheets 422 are included, the multiple mask sheets 422 may be arranged on the mask frame 421 so as to be adjacent to each other along one side of the mask frame 421 and may block the opening of the mask frame 421. For ease of description, the case where multiple mask sheets 422 are included will now be described in more detail.

[0308] The mask sheet 422 may include a first main body unit and a second main body unit, wherein the first main body unit includes a first opening 422a and the second main body unit includes a second opening 422b. The first opening 422a and the second opening 422b may have different shapes and / or sizes from each other. For example, the size of the planar shape of each first opening 422a may be different from the size of the planar shape of each second opening 422b. For example, Figure 24 As shown in , the planar size of each first opening 422 a may be larger than the planar size of each second opening 422 b . The planar size of the opening may be the planar size of the opening on one surface of the mask sheet 422 facing the deposition source 450 .

[0309] The mask assembly 420 may further include a support frame (not shown) arranged on the mask frame 421. The support frame may be arranged in an opening of the mask frame 421 and may block gaps between the mask sheets 422, or may be arranged in a direction perpendicular to the length direction of the mask sheets 422.

[0310] The substrate 100 may be seated on the first support 430. In this case, the first support 430 may adjust the position of the substrate 100. For example, the first support 430 may include a UVW stage (not shown).

[0311] The mask assembly 420 may be seated on the second support 440. In this case, similar to the first support 430, the second support 440 may adjust the position of the mask assembly 420.

[0312] At least one of the first support member 430 and the second support member 440 may ascend or descend within the chamber 410. In this case, at least one of the first support member 430 and the second support member 440 may adjust a gap between the display substrate D and the mask frame 421.

[0313] The deposition material may be contained in the deposition source 450, then evaporated or sublimated and provided to the chamber 410. The deposition source 450 may include a heater therein, and the deposition material within the deposition source 450 may be heated according to the operation of the heater to melt or sublime the deposition material. In this case, the deposition source 450 may be arranged at the center or corner of the chamber 410. Hereinafter, for ease of description, the case where the deposition source 450 is arranged at the center of the chamber 410 will be described in more detail.

[0314] The magnetic force generator 460 may be disposed within the chamber 410 and may bring the substrate 100 and the mask assembly 420 into close contact with each other. In this case, the magnetic force generator 460 may include, for example, an electromagnet or a permanent magnet that generates a magnetic force.

[0315] The vision unit 470 may be disposed within the chamber 410 and may photograph respective positions of the mask assembly 420 and the substrate 100. The vision unit 470 may photograph an alignment mark or the like of at least one of the mask assembly 420 and the substrate 100.

[0316] The pressure regulator 480 may be connected to the chamber 410 and may adjust the internal pressure of the chamber 410. The pressure regulator 480 may include a connection pipe 481 connected to the chamber 410 and a pump 482 provided on the connection pipe 481.

[0317] In operation of the apparatus 400, when the pressure regulator 480 maintains the internal pressure of the chamber 410 equal to, substantially equal to, or similar to atmospheric pressure, the gate valve 411 may be opened, and the display substrate D and the mask assembly 420 may be inserted into the chamber 410. In this case, at least one of the display substrate D and the mask assembly 420 may be moved by a robotic arm disposed outside the chamber 410 or a shuttle inserted into or extracted from the chamber 410. In this case, as shown in FIG. Figure 25 As shown in , the display substrate D may include a substrate 100 , a layer disposed under the pixel defining layer 119 , the pixel defining layer 119 , and a pixel electrode.

[0318] After the mask frame 421 and the display substrate D are placed on the second support 440 and the first support 430, respectively, the positions of the mask frame 421 and the display substrate D can be sensed by the vision unit 470 and can be arranged. Thereafter, the display substrate D and the mask frame 421 are brought close to each other and then brought into close contact with each other by the magnetic force generator 460.

[0319] When the deposition source 450 emits the deposition material, the deposition material may be deposited on the display substrate D through the first opening 422a and the second opening 422b of the mask sheet 422 and may form a pattern. In this case, the deposition material may be deposited on the display substrate D and may form at least one of the intermediate layers.

[0320] In this case, the deposition material that has passed through the first opening 422a and the second opening 422b of the mask sheet 422 can be deposited in the first display area DA1 and the second display area DA2 of the display substrate D, and thus, at least one intermediate layer can be formed in the first display area DA1 and the second display area DA2. Hereinafter, for the convenience of description, the case of forming the second main emission layer 222b-2 of the second main sub-pixel Pm2 and the second auxiliary emission layer 222b'-2 of the second auxiliary sub-pixel Pa2 by the device 400 will be described in more detail.

[0321] Specifically, the deposition material passing through the first opening 422a may be deposited on the adjacent second auxiliary pixel electrodes 221'-2. In this case, the deposition material may also be deposited on the pixel defining layer 119 disposed between the adjacent second auxiliary pixel electrodes 221'-2, thereby forming a second auxiliary emission layer 222b'-2 integrally formed on the adjacent second auxiliary pixel electrodes 221'-2.

[0322] The second main emission layer 222b-2 may be formed on the second main pixel electrode 221-2 while the above operation is being performed. In this case, the second main emission layer 222b-2 and the second auxiliary emission layer 222b'-2 may be separated from each other.

[0323] When the above-described processes are completed, the display substrate D may be carried out of the chamber 410 or may be moved to another location in the chamber 410 so that another layer may be formed on the display substrate D.

[0324] In addition to the above processes, the first main emission layer and the first auxiliary emission layer may be formed concurrently (e.g., simultaneously), and the third main emission layer and the third auxiliary emission layer may be formed concurrently (e.g., simultaneously). Thereafter, the second functional layer, the counter electrode, etc. may be formed concurrently (e.g., simultaneously).

[0325] In this case, the manufacturing method described above is only one embodiment, and in the case of forming the main emission layer and the auxiliary emission layer, the deposition materials may be deposited in various suitable orders to achieve or provide the same color.

[0326] Therefore, the device 400 can form an intermediate layer having a precise pattern in the first and second display areas DA1 and DA2. The device 400 can also form an intermediate layer having a pattern almost identical to a design pattern in the first or second display areas DA1 and DA2.

[0327] As described above, since a plurality of auxiliary sub-pixels emitting light of the same color from among the auxiliary sub-pixels in the second display area can share certain layers (eg, an intermediate layer), this embodiment can provide a display device capable of ensuring a transmission area as large as possible.

[0328] The present embodiment can provide a display device that reduces noise during operation of an optical element or the like arranged in the second display area.
