[0026] In the following description, embodiments of the inventive concept will be described more fully with reference to the accompanying drawings. Throughout the drawings, the same reference numerals may refer to the same elements.

[0027] In this disclosure, when a component such as a membrane, region, layer, or element is referred to as being “on,” “connected to,” “coupled to,” or “adjacent to” another component, the component may be directly on, directly connected to, directly coupled to, or directly adjacent to the other component, or there may be intermediary components. Unless the context clearly indicates otherwise, the term “adjacent to” may also mean “closestly adjacent to” or “most closely adjacent to.” It will also be understood that when a component is referred to as being “between” two components, the component may be the only component between the two components, or there may be one or more intermediary components. It will also be understood that when a component is referred to as “covering” another component, the component may be the only component covering the other component, or one or more intermediary components may also cover the other component. Other terms used to describe relationships between components should be interpreted in a similar manner.

[0028] The term "and / or" includes all combinations of one or more of the associated configurations that can be defined.

[0029] It will be understood that while the terms “first,” “second,” etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of embodiments of the inventive concept, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

[0030] Unless the context clearly indicates otherwise, a singular term may include a plural term.

[0031] For ease of description, spatial relative terms such as “below,” “under,” “below,” “below,” “above,” and “above” may be used herein to describe the relationship of one element or feature to another element (or features) or feature (or features) as shown in the accompanying drawings. It will be understood that, in addition to the orientations depicted in the drawings, the spatial relative terms are also intended to cover different orientations of the device in use or operation. For example, if the device in the accompanying drawings is flipped, an element described as “below” or “below” or “below” other elements or features will subsequently be oriented “above” other elements or features. Thus, the exemplary terms “below” and “below” can cover both above and below orientations.

[0032] It should be understood that the terms “comprising,” “including,” or “having” are intended to describe the presence of the features, integrals, steps, operations, elements, components, or combinations thereof stated in this disclosure, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0033] It should be understood that, unless the context clearly indicates otherwise, the description of features or aspects within each embodiment should generally be considered as applicable to other similar features or aspects in other embodiments.

[0034] Here, when two or more elements or values ​​are described as substantially the same or approximately equal to each other, it will be understood that the elements or values ​​are the same, the elements or values ​​are equal to each other within measurement error, or, as those skilled in the art will understand, if they are measurably unequal, the elements or values ​​are sufficiently close in value to be functionally equal to each other. For example, taking into account the measurements discussed and the errors associated with the measurement of a particular quantity (e.g., limitations of the measurement system), the term “approximately” as used herein includes the stated value and refers to an acceptable deviation from a particular value as determined by those skilled in the art. For example, as those skilled in the art will understand, “approximately” can mean within one or more standard deviations. Furthermore, it will be understood that although a parameter may be described herein as having “approximately” a certain value, according to embodiments, as those skilled in the art will understand, the parameter may be exactly that particular value, or approximately that particular value within measurement error. It will be further understood that when two components or directions are described as extending substantially parallel or perpendicular to each other, as those skilled in the art will understand, the two components or directions extend exactly parallel or perpendicular to each other, or approximately parallel or perpendicular to each other within measurement error. These terms, and other uses of similar terms, which describe the relationships between components, should be interpreted in a similar manner.

[0036] Reference Figure 1 The display device DD may include a display area DA, a functional element FE disposed in the display area DA, and a non-display area NDA adjacent to the display area DA. The non-display area NDA may surround the display area DA. The display area DA displays an image, while the non-display area NDA does not display an image. The non-display area NDA may define the edge of the display device DD and may be printed in a predetermined color. For example, the non-display area NDA may correspond to the border portion of the display device DD.

[0037] The functional element FE can be disposed near the upper end of the display device DD, and in the portion of the display area DA adjacent to the right side of the display device DD. However, the placement of the functional element FE is not limited to this. For example, the functional element can be disposed near the other end of the display device DD besides the upper end, and in the portion of the display area DA adjacent to the other side of the display device DD besides the right side. Figure 1As shown, the functional element FE may include a camera. However, the functional element FE is not limited to this. For example, according to an embodiment, the functional element FE may include a speaker and / or a sensor with various functions. When multiple functional elements FE are provided, the multiple functional elements FE may be arranged at various locations in the display area DA.

[0038] The display device DD may have a rectangular shape having a long side extending in a first direction DR1 and a short side extending in a second direction DR2 intersecting the first direction DR1 (relative to the long side). However, embodiments of the inventive concept are not limited thereto. For example, according to embodiments, the display device DD may have various shapes, such as circles and polygons. The vertices of the quadrilateral shape of the display device DD may be formed as curves. For example, according to embodiments, the display device DD may have a rounded rectangular shape.

[0039] In the following text, the direction that intersects substantially perpendicularly with the plane defined by the first direction DR1 and the second direction DR2 is defined as the third direction DR3. The third direction DR3 may also be referred to herein as the thickness direction of the display device DD. In this disclosure, "when viewed in a plane" or "when viewed in a plan view" may refer to when viewed from the third direction DR3.

[0040] The upper surface of the display device DD can be defined as a display surface and can have a plane defined by a first direction DR1 and a second direction DR2. Images generated by the display device DD can be provided to the user through the display surface. The images displayed by the display device DD can be, for example, icon images (multiple icon images) corresponding to a specific function of the display device DD. When a user touches an icon image IM displayed on the display surface, a specific function can be provided to the user, the specific function including providing an image corresponding to the icon image IM.

[0041] exist Figure 1 In this document, the display device DD is exemplarily shown as a mobile phone. However, the display device DD is not limited to this. For example, according to embodiments, the display device DD can be used in large electronic devices such as televisions or outdoor billboards, and also in small and medium-sized electronic devices such as personal computers, laptop computers, car navigation system units, game consoles, and tablet computers. However, these are merely examples, and the display device DD can be used in other electronic devices not described herein.

[0043] Reference Figure 2According to an embodiment of the present invention, the display device DD may include a display module DM, a power module PM, a first electronic module EM1, and a second electronic module EM2. The display module DM, power module PM, first electronic module EM1, and second electronic module EM2 may be electrically connected to each other. The power module PM may supply power for the operation of the display device DD. The power module may include a battery.

[0044] The first electronic module EM1 and the second electronic module EM2 may include various functional modules for operating the display device DD. The first electronic module EM1 and the second electronic module EM2 may be directly mounted on the motherboard electrically connected to the display module DM, or the first electronic module EM1 and the second electronic module EM2 may be mounted on a separate substrate and electrically connected to the motherboard via, for example, a connector.

[0045] The first electronic module EM1 may include, for example, a control module CM, a wireless communication module TM, an image input module IIM, a voice input module AIM, a memory MM, and an external interface IF. The control module CM controls the overall operation of the display device DD and can activate or disable the display module DM. The control module CM can control other modules, such as the image input module IIM or the voice input module AIM, based on touch signals received from the display module DM.

[0046] The wireless communication module TM can send / receive wireless signals to other terminals using, for example, BLUETOOTH or Wi-Fi, or it can send / receive voice signals using a common communication line. The wireless communication module TM may include a transmitting unit TM1 configured to transmit signals and a receiving unit TM2 configured to receive signals. The wireless communication module TM may also be referred to as a transceiver.

[0047] The Image Input Module (IIM) processes image signals and converts the processed image signals into image data that can be displayed on the Display Module (DM). The Audio Input Module (AIM) receives external audio signals via a microphone in modes such as recording or voice recognition, and converts the received external audio signals into electronic voice data. The External Interface Module (IF) can be used as an interface for connecting to devices such as external chargers, wired / wireless data ports, and card slots (e.g., memory cards, SIM / UIM cards, etc.).

[0048] The second electronic module EM2 may include, for example, a sound output module AOM, a light emission module LM, a light receiving module LRM, and a camera module CMM. The sound output module AOM can convert sound data received from the wireless communication module TM or sound data stored in the memory MM, and output the converted sound data to the external display device DD.

[0049] The light-emitting module (LM) generates and outputs infrared light. The LM can sense infrared radiation. The light-receiving module (LRM) may include a CMOS sensor, which can be activated when a predetermined level or higher of infrared radiation is sensed. Infrared radiation is output from the LM and then reflected by an external object; the reflected infrared light can then be incident on the LRM.

[0050] The camera module (CMM) can capture external images. The speaker in the sound output module (AOM), the camera in the camera module (CMM), and the sensor in the light receiving module (LRM) can all be the aforementioned functional components (FE).

[0051] The display module DM may include a display panel DP and an input sensing section ISP. The display panel DP can display images using image data provided by the control module CM. The input sensing section ISP senses external input (e.g., a user's finger or hand) and can convert the sensed signals into input signals and transmit them to the control module CM. The control module CM can control the operation of the display panel DP in response to the input signals from the input sensing section ISP.

[0054] The display panel DP may include a display area DA and a non-display area NDA adjacent to the display area DA. The display area DA may include a first display area DA1, a second display area DA2 adjacent to the first display area DA1, and a boundary area BA disposed between the first display area DA1 and the second display area DA2. The second display area DA2 may surround the first display area DA1. The first display area DA1 may also be referred to herein as the first area, and the second display area DA2 may also be referred to herein as the second area.

[0055] The display panel DP can be a flexible display panel. Furthermore, the display panel DP according to embodiments of the present invention can be a light-emitting display panel, but is not specifically limited thereto. For example, the display panel DP can be an organic light-emitting display panel or a quantum dot light-emitting display panel. The light-emitting layer of an organic light-emitting display panel may include, for example, organic light-emitting materials. The light-emitting layer of a quantum dot light-emitting display panel may include, for example, quantum dots and quantum rods. Hereinafter, the display panel DP will be described as an organic light-emitting display panel.

[0056] The input sensing component (ISP) can be disposed on the display panel (DP). The ISP may include multiple sensors for sensing external input. These sensors may sense the external input capacitively. In one embodiment, the ISP can be directly fabricated on the display panel (DP) during its fabrication. However, embodiments of the present invention are not limited thereto. For example, according to an embodiment, the ISP can be fabricated as a panel separate from the display panel (DP) and attached to it via a pressure-sensitive adhesive layer. Therefore, according to an embodiment, the ISP can be integrally formed with the display panel (DP), or it can be formed separately and attached to the display panel (DP).

[0057] An anti-reflective layer (RPL) can be disposed on the input sensing section (ISP). The RPL can be an anti-external light reflection film. The RPL reduces the reflectivity of external light incident from above the display device (DD) towards the display panel (DP). The RPL may include a phase delayer and / or a polarizer.

[0058] The window (WIN) can be placed on the anti-reflective layer (RPL). The window (WIN) protects the display panel (DP), input sensing component (ISP), and anti-reflective layer (RPL) from external impacts and scratches. The window (WIN) may include optically transparent properties, and therefore, it can also be referred to as an optically transparent window (WIN).

[0059] A cover layer CVL can be disposed below the display panel DP. The cover layer CVL protects the display panel DP from external impacts applied to its underside. The cover layer CVL may include a foam sheet with predetermined elasticity and can absorb external impacts.

[0060] The first pressure-sensitive adhesive layer AL1 to the third pressure-sensitive adhesive layer AL3 may include a first pressure-sensitive adhesive layer AL1, a second pressure-sensitive adhesive layer AL2, and a third pressure-sensitive adhesive layer AL3. The first pressure-sensitive adhesive layer AL1 may be disposed between the display panel DP and the cover layer CVL. The display panel DP and the cover layer CVL can be bonded to each other through the first pressure-sensitive adhesive layer AL1. The second pressure-sensitive adhesive layer AL2 may be disposed between the anti-reflective layer RPL and the input sensing component ISP. The anti-reflective layer RPL and the input sensing component ISP can be bonded to each other through the second pressure-sensitive adhesive layer AL2. The third pressure-sensitive adhesive layer AL3 may be disposed between the window WIN and the anti-reflective layer RPL. The window WIN and the anti-reflective layer RPL can be bonded to each other through the third pressure-sensitive adhesive layer AL3.

[0061] The functional element FE can be disposed below the first display area DA1. When viewed in a plane, an aperture HO can be defined in the portion of the overlay layer CVL that overlaps with the first display area DA1. The functional element FE can be disposed within the aperture HO. As described above, the functional element FE can include a camera. External light can be provided to the camera through the window WIN.

[0062] Figure 4 This is an example shown Figure 3 The image shows a cross-sectional view of the display panel.

[0063] Reference Figure 4 The display panel DP may include a substrate SUB, a circuit element layer DP-CL disposed on the substrate SUB, a display element layer DP-OLED disposed on the circuit element layer DP-CL, and a thin film encapsulation layer TFE disposed on the display element layer DP-OLED.

[0064] The substrate SUB may include a display area DA and a non-display area NDA adjacent to the display area DA. The non-display area NDA may surround the display area DA. The substrate SUB may include a flexible plastic material. For example, the substrate SUB may include polyimide (PI).

[0065] The display element layer DP-OLED can be disposed in the display area DA. The thin film encapsulation layer TFE can be disposed on the circuit element layer DP-CL and can cover the display element layer DP-OLED.

[0066] Multiple pixels can be disposed on the circuit element layer DP-CL and the display element layer DP-OLED. For example, each of the pixels may include a transistor disposed on the circuit element layer DP-CL and a light-emitting element disposed on the display element layer DP-OLED to connect to the transistor.

[0067] Figure 5 yes Figure 4 The diagram shows a floor plan of the display panel.

[0068] Reference Figure 5 Display device DD (see Figure 3 The device may include a display panel (DP), a scan driver (SDV), a data driver (DDV), an EDV, a printed circuit board (PCB), and a timing controller (T-CON). The display panel (DP) may have a rectangular shape, having a long side extending in a first direction (DR1) and a short side extending in a second direction (DR2) (relative to the long side). However, the shape of the display panel (DP) is not limited to this.

[0070] In an embodiment, such as Figure 5 As shown, the first display area DA1 can have a circular shape. However, the shape of the first display area DA1 is not limited to this. As mentioned above, the functional element FE can be disposed below the first display area DA1. In an embodiment, as... Figure 5 As shown, the first display area DA1 is adjacent to the upper and right sides of the second display area DA2. However, the position of the first display area DA1 is not limited to this.

[0071] The display panel DP may include multiple pixels PX, multiple scan lines SL, multiple data lines DL, multiple light emission lines EL, a first control line CSL1 and a second control line CSL2, a first power line PL1 and a second power line PL2, a connection line CNL, and multiple pads PD.

[0072] Pixels (PX) can be located in the display area (DA). Scan driver (SDV) and light-emitting driver (EDV) can be located in the non-display area (NDA). The scan driver (SDV) can be positioned adjacent to one long side of the display panel (DP), and the light-emitting driver (EDV) can be positioned adjacent to the opposite long side of the display panel (DP). The data driver (DDV) can be located in the non-display area (NDA) and can be adjacent to any of the short sides of the display panel (DP) (relative to the long side of the display panel (DP)). When viewed in a plane, the data driver (DDV) can be adjacent to the bottom edge of the display panel (DP). The data driver (DDV) can be manufactured as an integrated circuit chip and mounted on the display panel (DP).

[0073] The scan line SL can extend in the second direction DR2 and can be connected to the pixel PX and the scan driver SDV. The data line DL can extend in the first direction DR1 and can be connected to the pixel PX and the data driver DDV. The light-emitting line EL can extend in the second direction DR2 and can be connected to the pixel PX and the light-emitting driver EDV.

[0074] The first power line PL1 may extend along the first direction DR1 and may be located in the non-display area NDA. The first power line PL1 may be located between the display area DA and the light-emitting driver EDV. However, the location of the first power line PL1 is not limited to this. The first power line PL1 may also be located between the display area DA and the scan driver SDV.

[0075] The connecting line CNL can extend along the second direction DR2 and be arranged along the first direction DR1, such that the connecting line CNL is connected to the first power line PL1 and the pixel PX. A first voltage can be applied to the pixel PX through the first power line PL1 and the connecting line CNL connected to each other.

[0076] The second power line PL2 can be located in the non-display area NDA. The second power line PL2 can extend along the long side of the display panel DP and the other short side of the display panel DP where the data driver DDV is not located. The second power line PL2 can be located in the peripheral area of ​​the scan driver SDV and the light-emitting driver EDV.

[0077] The second power supply line PL2 can extend toward the display area DA and can be connected to the pixel PX. A second voltage with a lower level than the first voltage can be applied to the pixel PX through the second power supply line PL2.

[0078] The first control line CSL1 can be connected to the scan driver SDV and can extend towards the bottom of the display panel DP. The second control line CSL2 can be connected to the light-emitting driver EDV and can also extend towards the bottom of the display panel DP. The data driver DDV can be positioned between the first control line CSL1 and the second control line CSL2.

[0079] The pad PD can be set on the display panel DP. The pad PD can be adjacent to the bottom of the display panel DP. The data driver DDV, the first power line PL1, the second power line PL2, the first control line CSL1, and the second control line CSL2 can be connected to the pad PD. The data line DL can be connected to the data driver DDV, and the data driver DDV can be connected to the pad PD corresponding to the data line DL.

[0080] A printed circuit board (PCB) can be connected to pads (PD). A timing controller (T-CON) can be manufactured as an integrated circuit chip and mounted on the PCB. The timing controller T-CON can be connected to pads (PD) via the PCB, which are connected to a data driver (DDV) and first control lines (CSL1) and second control lines (CSL2). A voltage generator for generating the first and second voltages can be located on the PCB and connected to pads (PD), which are connected to first power line (PL1) and second power line (PL2).

[0081] The timing controller T-CON can output scan control signals, data control signals, light emission control signals, and image signals.

The data driver (DDV) generates multiple data voltages corresponding to the image signals in response to a data control signal. These data voltages are applied to pixel PX via data line DL. The light emission driver (EDV) generates multiple light emission signals in response to a light emission control signal, and these light emission signals are applied to pixel PX via light emission line EL.

[0083] A pixel (PX) can be supplied with a data voltage in response to a scan signal. A pixel (PX) can display an image by emitting light of a brightness corresponding to the data voltage in response to a light emission signal. The duration of light emission by a pixel (PX) can be controlled by the light emission signal.

[0084] Figure 6 It is shown Figure 5 The view shows the configuration of the first display area, the boundary area, and the second display area adjacent to the boundary area.

[0085] Reference Figure 6 A pixel PX may include multiple first pixels PX1, multiple second pixels PX2, and multiple dummy pixels DPX. The first pixels PX1 may be set in the first display area DA1, the second pixels PX2 may be set in the second display area DA2, and the dummy pixels DPX may be set in the boundary area BA.

[0086] exist Figure 6 In the embodiment, the boundary region BA adjacent to the second display region DA2 is schematically shown to have an octagonal shape. However, the shape of the boundary region BA is not limited to this.

[0087] The first pixel PX1 can be arranged in a matrix within the first display area DA1. For example, the first pixel PX1 can be arranged in the first direction DR1 and the second direction DR2. However, the arrangement of the first pixel PX1 is not limited to this.

[0088] The second pixel PX2 can be arranged in a matrix within the second display area DA2. For example, the second pixel PX2 can be arranged in the first direction DR1 and the second direction DR2. However, the arrangement of the second pixel PX2 is not limited to this.

[0089] The dummy pixel DPX can surround the first display area DA1 along the boundary region BA. Since the functional element FE is located below the first display area DA1, the dummy pixel DPX can surround the functional element FE when viewed in a plane. Therefore, when viewed in a plane, the dummy pixel DPX can be positioned between the functional element FE and the second display area DA2.

[0090] exist Figure 6 In one embodiment, dummy pixels DPX are shown arranged in a row to surround the first display area DA1 along the boundary region BA. However, the arrangement of dummy pixels DPX is not limited to this. For example, according to an embodiment, dummy pixels DPX can be arranged in multiple rows. Here, a row refers to a row in which dummy pixels DPX are arranged in a particular direction (e.g., forming...). Figure 6 The arrangement of the circles in the middle (in the direction of their curvature) one by one.

[0091] The first display area DA1 can display an image via the first pixel PX1, the second display area DA2 can display an image via the second pixel PX2, and the boundary area BA can display an image via the dummy pixel DPX. In the display area DA, a predetermined image can be displayed using light generated from the first pixel PX1, the second pixel PX2, and the dummy pixel DPX.

[0092] Referring to the comparative example, if the dummy pixel DX is not set in the boundary region BA, the user can visually identify the boundary region BA. For example, in this case, the boundary region BA may appear as a ring to the user viewing the display panel DP, thereby reducing the display quality of the display panel DP. However, in the embodiments of the present invention, since light is generated in the boundary region BA by the dummy pixel DPX, the user cannot visually identify the boundary region BA, or the user is less likely to visually identify the boundary region BA, thereby improving the display quality of the display panel DP.

[0093] The first pixel PX1 can have a shape that is substantially the same as the dummy pixel DPX. The second pixel PX2 can have a shape that is different from both the first pixel PX1 and the dummy pixel DPX. The shapes of the first pixel PX1, the dummy pixel DPX, and the second pixel PX2 will be described in more detail below.

[0094] The display panel DP may include multiple transmissive regions TA. The transmissive regions TA may be located between adjacent first pixels PX1 within the first pixel PX1. Furthermore, the transmissive regions TA may be located between a dummy pixel DPX and a first pixel PX1 adjacent to the dummy pixel DPX.

[0095] exist Figure 6 In some embodiments, the transmission region TA has a cross shape. However, the shape of the transmission region TA is not limited to this. The transmission region TA can be disposed around each first pixel PX1. For example, each first pixel PX1 can be surrounded by multiple transmission regions TA. The transmission region TA can be disposed relative to each first pixel PX1 in a first diagonal direction DDR1 and a second diagonal direction DDR2.

[0096] The first diagonal direction DDR1 can be defined as the direction that intersects the first direction DR1 and the second direction DR2 on the plane defined by the first direction DR1 and the second direction DR2. The second diagonal direction DDR2 can be defined as the direction that intersects the first diagonal direction DDR1 on the plane defined by the first direction DR1 and the second direction DR2. The first direction DR1 and the second direction DR2 can intersect each other perpendicularly, and the first diagonal direction DDR1 and the second diagonal direction DDR2 can intersect each other perpendicularly.

[0097] exist Figure 6 In one embodiment, the first pixel PX1 may have a quadrilateral shape having sides extending substantially parallel to a first direction DR1 and sides extending substantially parallel to a second direction DR2. By being disposed adjacent to the vertices of each first pixel PX1, the transmission region TA may be disposed relative to each first pixel PX1 on a first diagonal direction DDR1 and a second diagonal direction DDR2. However, this placement is exemplary, and the placement of the transmission region TA is not limited thereto.

[0098] The dummy pixel DPX can have a quadrilateral shape, the quadrilateral shape having sides extending substantially parallel to a first direction DR1 and sides extending substantially parallel to a second direction DR2. The transmission region TA can be adjacent to some vertices of each dummy pixel DPX.

[0099] The number of transmission regions TA adjacent to each dummy pixel DPX (e.g., most closely adjacent) can be less than the number of transmission regions TA adjacent to each first pixel PX1 (e.g., most closely adjacent). For example, in an embodiment, the number of transmissive regions TA adjacent to (e.g., most closely adjacent to) the first pixel PX1_1 can be 4, the number of transmissive regions TA adjacent to (e.g., most closely adjacent to) some dummy pixels DPX' can be 2, and the number of transmissive regions TA adjacent to (e.g., most closely adjacent to) some other dummy pixels DPX" can be 1. For example, in an embodiment, 4 transmissive regions TA can be directly adjacent to the first pixel PX1_1 disposed in the first display area DA1 (e.g., 4 transmissive regions can surround each first pixel PX1_1), 2 transmissive regions TA can be set to be directly adjacent to the dummy pixel DPX' disposed in the boundary area BA surrounding the first display area DA1, and 1 transmissive region TA can be set to be adjacent to the dummy pixel DPX" disposed in the boundary area BA surrounding the first display area DA1.

[0100] Here, when two specific elements "A" are described as "directly adjacent" to each other, this can mean that no other element "A" is placed between the two adjacent specific elements "A". Similarly, when specific elements "A" and specific elements "B" are described as "directly adjacent" to each other, this can mean that no other element "A" is placed between the adjacent specific elements "A" and "B" and no other element "B" is placed between them. Unless the context clearly indicates otherwise, other uses of the term "directly adjacent" should be interpreted in a similar manner.

[0101] The transmissive region TA can have a higher transmittance than the first pixel PX1 and the second pixel PX2. Light transmitted through the transmissive region TA can be provided to the functional element FE located below the first display area DA1.

[0102] An image can be displayed by the first pixel PX1 in the first display area DA1, and light can be provided to the functional element FE through the transmission area TA. Therefore, the first display area DA1 can display an image, and the functional element FE, which is provided with light, can perform a specific function (e.g., when the functional element FE is a camera, the specific function of the functional element FE can be to capture an image).

[0103] The interval between a dummy pixel DPX and its adjacent second pixel PX2 can be defined as a first interval DT1. That is, the interval between a dummy pixel DPX and its closest adjacent second pixel PX2 can be defined as the first interval DT1. The interval between adjacent first pixels PX1 can be defined as a second interval DT2. That is, the interval between the closest adjacent first pixels PX can be defined as the second interval DT2. In this disclosure, "interval between adjacent components" can refer to the interval between two adjacent components. Here, the terms "interval" and "distance" can be used interchangeably.

[0104] The second interval DT2 can be defined as the interval between adjacent first pixels PX1 in the first direction DR1 and the interval between adjacent first pixels PX1 in the second direction DR2. The first interval DT1 can be smaller than the second interval DT2. Referring to the following... Figure 7 , Figure 8 and Figure 9 The first interval DT1 is described in more detail.

[0105] Along the boundary region BA surrounding the first display area DA1, the spacing between the dummy pixel DPX and the second pixel PX2 can be consistently maintained. For example, a first spacing DT1 between the dummy pixel DPX and the second pixel PX2 can be consistently maintained along the boundary region BA. For example, according to an embodiment, the first spacing DT1 may refer to the distance in the first direction DR1 and the second direction DR2 between the dummy pixel DPX located in the boundary region BA and the nearest second pixel PX2 located in the second display area DA2, and the first spacing DT1 can be consistent along the boundary region BA for all dummy pixels DPX. That is, according to an embodiment, the distance in the first direction DR1 and the second direction DR2 between the dummy pixel DPX and their respective nearest neighboring second pixel PX2 located in the second display area DA2 can be consistent (e.g., it can be DT1). According to an embodiment, the first spacing DT1 in the first direction DR1 and the second direction DR2 between each of the dummy pixels DPX and the nearest second pixel PX2 can be consistent. In other words, according to an embodiment, none of the first spacings DT1 are inconsistent.

[0106] Referring to the comparison example, when the spacing between the dummy pixel DPX and the second pixel PX2 is not consistent, a difference in brightness can be visually identified. For example, in the portion where the spacing between the dummy pixel DPX and the second pixel PX2 is relatively large, the brightness will be visually perceived as lower than the surrounding portion, and therefore, the brightness will be visually perceived as banded color spots, thereby reducing the display quality of the display panel DP.

[0107] However, in the embodiments of the present invention, since the spacing between the dummy pixel DPX and the second pixel PX2 is kept consistent, the brightness in the boundary region BA can be kept constant. As a result, visual defects such as banded color spots that may occur in the boundary region BA can be prevented or reduced.

[0110] Reference Figure 6 and Figure 7 The dummy pixel DPX may include a plurality of first dummy pixels DPX1 disposed in the boundary region BA and substantially parallel to the second direction DR2. The first dummy pixels DPX1 may be arranged on the second direction DR2.

[0111] The first interval DT1 between the first dummy pixel DPX1 and the second pixel PX2, which is adjacent to the first dummy pixel DPX1 (e.g., most closely adjacent) in the first direction DR1, may be smaller than the second interval DT2. The first interval DT1 may be defined as the interval between the first dummy pixel DPX1 and the second pixel PX2 measured in the first direction DR1.

[0112] Figure 7 This shows a portion of the lower side of the boundary region BA that defines the boundary region BA. Referring to a portion of the upper side of the boundary region BA that defines the boundary region BA, similar to... Figure 7 In the corresponding part shown, the first interval DT1 can be defined as the interval between the dummy pixel DPX and the second pixel PX2 measured in the first direction DR1.

[0113] Reference Figure 6 and Figure 8 The dummy pixel DPX may include a plurality of second dummy pixels DPX2 disposed in the boundary region BA and substantially parallel to the first direction DR1. The second dummy pixels DPX2 may be arranged on the first direction DR1.

[0114] The first interval DT1 between the second dummy pixel DPX2 and the second pixel PX2 that is adjacent to (e.g., most closely adjacent to) the second dummy pixel DPX2 in the second direction DR2 can be smaller than the second interval DT2. The first interval DT1 can be defined as the interval between the second dummy pixel DPX2 and the second pixel PX2 measured in the second direction DR2.

[0115] Figure 8 This shows a portion of the right side of the boundary region BA. Referring to a portion of the left side of the boundary region BA, it is similar to... Figure 8 In the corresponding part shown, the first interval DT1 can be defined as the interval between the dummy pixel DPX and the second pixel PX2 measured in the second direction DR2.

[0116] Reference Figure 6 and Figure 9 The dummy pixel DPX may include a plurality of third dummy pixels DPX3 disposed in the boundary region BA and substantially parallel to the first diagonal direction DDR1. The third dummy pixels DPX3 may be arranged on the first diagonal direction DDR1.

[0117] The first interval DT1 between the third dummy pixel DPX3 and the second pixel PX2, which is adjacent to (e.g., most closely adjacent to) the third dummy pixel DPX3 in the first direction DR1, can be smaller than the second interval DT2. Furthermore, the first interval DT1 between the third dummy pixel DPX3 and the second pixel PX2, which is adjacent to (e.g., most closely adjacent to) the third dummy pixel DPX3 in the second direction DR2, can be smaller than the second interval DT2. That is, the first interval DT1 can be defined as the interval between the third dummy pixel DPX3 and the second pixel PX2 measured in the first direction DR1 and the interval between the third dummy pixel DPX3 and the second pixel PX2 measured in the second direction DR2.

[0118] Figure 9 The diagram shows a portion of the boundary region BA that defines the lower right side of DDR1, substantially parallel to the first diagonal direction. Referring to other portions of the boundary region BA substantially parallel to the first diagonal direction (DDR1) and substantially parallel to the second diagonal direction (DDR2), similar... Figure 9As shown in the corresponding part, the first interval DT1 can be defined as the interval between the dummy pixel DPX and the second pixel PX2 measured in each of the first direction DR1 and the second direction DR2.

[0119] Reference Figures 6 to 9 According to an embodiment of the present invention, the first interval DT1 between the dummy pixel DPX and the second pixel PX2 measured along the boundary region BA in the first direction DR1 and the second direction DR2 can remain consistent.

[0120] Figure 10 It is shown Figure 6 The plan view shows the configuration of the first pixel.

[0121] Reference Figure 10 This illustrates two first pixels PX1 that are adjacent to each other (e.g., closest to each other) in the second direction DR2. The structure of any one of the first pixels PX1 will be described below, and it will be understood that the structure of each of the plurality of first pixels PX1 can be compared with that of the referenced... Figure 10 The structures described are the same.

[0122] Reference Figure 10 The first pixel PX1 may include multiple light-emitting areas PA1_1, PA2_1, and PA3_1 that can display multiple colors. The light-emitting areas PA1_1, PA2_1, and PA3_1 may include multiple first light-emitting areas PA1_1, multiple second light-emitting areas PA2_1, and multiple third light-emitting areas PA3_1.

[0123] Although Figure 10 The first pixel PX1 is shown as including two first light-emitting regions PA1_1, four second light-emitting regions PA2_1 and two third light-emitting regions PA3_1, but the number of each of the first light-emitting regions PA1_1, second light-emitting regions PA2_1 and third light-emitting regions PA3_1 set in the first pixel PX1 is not limited to this.

[0124] In this embodiment, the first luminescent region PA1_1 can display red, the second luminescent region PA2_1 can display green, and the third luminescent region PA3_1 can display blue. However, the color displayed by each of the first luminescent region PA1_1, the second luminescent region PA2_1, and the third luminescent region PA3_1 is not limited to this.

[0125] In an embodiment, such as Figure 10As shown, each of the first light-emitting region PA1_1, the second light-emitting region PA2_1, and the third light-emitting region PA3_1 may have a rectangular shape. However, the shapes of the first light-emitting region PA1_1, the second light-emitting region PA2_1, and the third light-emitting region PA3_1 are not limited to this.

[0126] The first light-emitting region PA1_1, the second light-emitting region PA2_1, and the third light-emitting region PA3_1 can be divided by a pixel-defining layer PDL. Furthermore, in this embodiment, the pixel-defining layer PDL is not disposed in the transmissive region TA. Figure 11 The pixel-defined layer (PDL) is shown in the figure.

[0127] The first luminous region PA1_1 and the third luminous region PA3_1 can extend in the first direction DR1. Here, when an element is described as "extending in one direction," this can mean that the element extends longitudinally in that direction. A pair of first luminous regions PA1_1 and third luminous regions PA3_1 can be arranged in a downward direction in the order of third luminous region PA3_1 and first luminous region PA1_1. Another pair of first luminous regions PA1_1 and third luminous regions PA3_1 can be arranged in the same downward direction in the order of first luminous region PA1_1 and third luminous region PA3_1. Therefore, the arrangement order of the first luminous regions PA1_1 and third luminous regions PA3_1 in adjacent (e.g., most closely adjacent) pairs of first luminous regions PA1_1 and third luminous regions PA3_1 can be alternated. A pair of first luminous regions PA1_1 and third luminous regions PA3_1 and another pair of first luminous regions PA1_1 and third luminous regions PA3_1 can be spaced apart from each other in the second direction DR2.

[0128] The second luminescent region PA2_1 can extend in the second direction DR2 and can be arranged in the first direction DR1. The second luminescent region PA2_1 can be located between a pair of first luminescent regions PA1_1 and third luminescent regions PA3_1 and another pair of first luminescent regions PA1_1 and third luminescent regions PA3_1.

[0129] Figure 11 It is along Figure 10 The cross-sectional view taken from line II-II'.

[0130] The cross-sectional structure of any first pixel PX1 will be described below.

[0131] Reference Figure 11The first pixel PX1 may include a transistor TR and a light-emitting element OLED. The light-emitting element OLED may include a first electrode AE, a second electrode CE, a hole control layer HCL, an electron control layer ECL, and a light-emitting layer EML. The transistor TR and the light-emitting element OLED may be disposed on a substrate SUB.

[0132] The first display area DA1 may include a light-emitting area PA and a non-light-emitting area NPA adjacent to the light-emitting area PA. The non-light-emitting area NPA may surround the light-emitting area PA. The light-emitting element OLED may be disposed within the light-emitting area PA. The light-emitting area PA may be... Figure 10 Any one of the first light-emitting region PA1_1, the second light-emitting region PA2_1, and the third light-emitting region PA3_1 shown in the figure.

[0133] A buffer layer BFL is formed on the substrate SUB, and a semiconductor pattern can be formed on the buffer layer BFL. The semiconductor pattern may include, for example, polycrystalline silicon. However, the semiconductor pattern is not limited thereto. For example, according to an embodiment, the semiconductor pattern may include, for example, amorphous silicon or metal oxide.

[0134] The electrical properties of a semiconductor pattern can vary depending on whether the semiconductor pattern is doped. A semiconductor pattern can include doped and undoped regions. Doped regions can be doped with N-type or P-type dopants. Doped regions have higher conductivity than undoped regions and can essentially serve as the source and drain electrodes of a transistor (TR). Undoped regions can essentially correspond to the active region (or channel) of a transistor.

[0135] The source (S), active region (A), and drain (D) of transistor TR can be formed from a semiconductor pattern. A first insulating layer (INS1) can be disposed on the semiconductor pattern. The gate (G) of transistor TR can be disposed on the first insulating layer (INS1). A second insulating layer (INS2) can be disposed on the gate (G). A third insulating layer (INS3) can be disposed on the second insulating layer (INS2).

[0136] The connecting electrode CNE can be disposed between the transistor TR and the light-emitting element OLED, and can connect the transistor TR and the light-emitting element OLED. The connecting electrode CNE can include a first connecting electrode CNE1 and a second connecting electrode CNE2.

[0137] The first connecting electrode CNE1 can be disposed on the third insulating layer INS3, and can be connected to the drain electrode D through the first contact hole CH1 defined in the first insulating layer INS1 to the third insulating layer INS3. The fourth insulating layer INS4 can be disposed on the first connecting electrode CNE1. The fifth insulating layer INS5 can be disposed on the fourth insulating layer INS4.

[0138] The second connecting electrode CNE2 can be disposed on the fifth insulating layer INS5. The second connecting electrode CNE2 can be connected to the first connecting electrode CNE1 through the second contact hole CH2 defined in the fourth insulating layer INS4 and the fifth insulating layer INS5. The sixth insulating layer INS6 can be disposed on the second connecting electrode CNE2. Each layer from the buffer layer BFL to the sixth insulating layer INS6 can be defined as the circuit element layer DP-CL.

[0139] A first electrode AE ​​can be disposed on a sixth insulating layer INS6. The first electrode AE ​​can be an anode electrode. The first electrode AE ​​can be connected to a second connecting electrode CNE2 through a third contact hole CH3 defined in the sixth insulating layer INS6. A pixel defining layer PDL can be disposed on the first electrode AE ​​and the sixth insulating layer INS6. An opening PX_OP exposing a predetermined portion of the first electrode AE ​​can be defined in the pixel defining layer PDL.

[0140] The hole control layer (HCL) can be disposed on the first electrode (AE) and the pixel definition layer (PDL). The HCL can also be disposed together in the light-emitting region (PA) and the non-light-emitting region (NPA). The HCL may include a hole transport layer and a hole injection layer.

[0141] The luminescent layer (EML) can be disposed on the hole control layer (HCL). The EML can be disposed in the region corresponding to the opening (PX_OP). The EML can include organic and / or inorganic materials. The EML can generate any of the following: red, green, and blue light.

[0142] The electronic control layer (ECL) can be disposed on the light-emitting layer (EML) and the hole control layer (HCL). The ECL can also be disposed together in the light-emitting region (PA) and the non-light-emitting region (NPA). The ECL may include an electron transport layer and an electron injection layer.

[0143] The second electrode CE can be disposed on the electronic control layer ECL. The second electrode CE can be a cathode electrode. The second electrodes CE can be disposed together in the first pixel PX1. The layer on which the light-emitting element OLED is disposed can be defined as the display element layer DP-OLED. The thin film encapsulation layer TFE can be disposed on the light-emitting element OLED.

[0144] A first voltage can be applied to the first electrode AE ​​via transistor TR, and a second voltage can be applied to the second electrode CE. Holes and electrons injected into the light-emitting layer EML are combined to form excitons, and when the excitons transition to the ground state, the light-emitting element OLED can emit light.

[0145] The light-emitting element (OLED) may not be disposed in the transmission region TA. This disclosure is not limited thereto; in some embodiments, the OLED may be disposed in the transmission region TA. The pixel defining layer (PDL) may be disposed on the transmission region TA and the sixth insulating layer INS6. Since the OLED is not disposed in the transmission region TA, the transmittance of the transmission region TA can be increased.

[0146] Figure 12 It is a plan view showing the configuration of a first dummy pixel and a second pixel adjacent to the first dummy pixel.

[0147] Figure 12 The dummy pixel DPX shown can be Figure 9 The third dummy pixel DPX3 is shown.

[0148] Reference Figure 12 The virtual pixel DPX can include multiple light-emitting regions DPA1_1, DPA2_1, and DPA3_1. The light-emitting regions DPA1_1, DPA2_1, and DPA3_1 can include multiple first light-emitting regions DPA1_1, multiple second light-emitting regions DPA2_1, and multiple third light-emitting regions DPA3_1.

[0149] The dummy pixel DPX can have the same as Figure 10 The configuration of the first pixel PX1 shown is substantially the same. For example, the first light-emitting area DPA1_1 can be the same as the first light-emitting area PA1_1 of the first pixel PX1, the second light-emitting area DPA2_1 can be the same as the second light-emitting area PA2_1 of the first pixel PX1, and the third light-emitting area DPA3_1 can be the same as the third light-emitting area PA3_1 of the first pixel PX1.

[0150] The second pixel PX2 may include multiple light-emitting regions PA1_2, PA2_2, and PA3_2 arranged on the first diagonal direction DDR1 and the second diagonal direction DDR2, which display multiple colors. The light-emitting regions PA1_2, PA2_2, and PA3_2 may include multiple first light-emitting regions PA1_2 configured to display red, multiple second light-emitting regions PA2_2 configured to display green, and multiple third light-emitting regions PA3_2 configured to display blue. However, the light-emitting regions PA1_2, PA2_2, and PA3_2 are not limited thereto.

[0151] The first luminescent region PA1_2, the second luminescent region PA2_2, and the third luminescent region PA3_2 can have the same characteristics as the first luminescent region DPA1_1, the second luminescent region DPA2_1, and the third luminescent region DPA3_1 of the virtual pixel DPX. Figure 10The first light-emitting region PA1_1, the second light-emitting region PA2_1, and the third light-emitting region PA3_1 of the first pixel PX1 shown have different shapes. For example, the first light-emitting region PA1_2, the second light-emitting region PA2_2, and the third light-emitting region PA3_2 can have a rhombus shape.

[0152] However, the shapes of the first light-emitting region PA1_2, the second light-emitting region PA2_2, and the third light-emitting region PA3_2 are not limited to this, as long as the first light-emitting region PA1_2, the second light-emitting region PA2_2, and the third light-emitting region PA3_2 have different shapes from the first light-emitting region DPA1_1, the second light-emitting region DPA2_1, and the third light-emitting region DPA3_1 of the dummy pixel DPX and the first light-emitting region PA1_1, the second light-emitting region PA2_1, and the third light-emitting region PA3_1 of the first pixel PX1.

[0153] The size of each first luminescent region PA1_2 can be larger than the size of each second luminescent region PA2_2. The size of each first luminescent region PA1_2 can be smaller than the size of each third luminescent region PA3_2. When viewed on a plane, the sizes of the first luminescent region PA1_2, the second luminescent region PA2_2, and the third luminescent region PA3_2 can be defined as the areas of the first luminescent region PA1_2, the second luminescent region PA2_2, and the third luminescent region PA3_2.

[0154] Reference Figure 10 and Figure 12 The area of ​​each of the first pixel PX1 and the dummy pixel DPX can be approximately the same as the area of ​​the four second pixels PX2. The sum of the areas of the first luminous region PA1_1, the second luminous region PA2_1, and the third luminous region PA3_1 of the first pixel PX1, and the sum of the areas of the first luminous region DPA1_1, the second luminous region DPA2_1, and the third luminous region DPA3_1 of the dummy pixel DPX, can be greater than the sum of the areas of the first luminous region PA1_2, the second luminous region PA2_2, and the third luminous region PA3_2 of the four second pixels PX2.

[0155] exist Figure 6 In this embodiment, since the transmissive region TA is located in the first display region DA1, the area of ​​the first pixel PX1 that generates light can be reduced. However, according to the embodiment, instead of reducing the area of ​​the first pixel PX1, the areas of the first light-emitting region PA1_1, the second light-emitting region PA2_1, and the third light-emitting region PA3_1 can be increased to improve the brightness of the light generated in the first pixel PX1.

[0156] For example, such as Figure 10As shown, relative to the areas of the first light-emitting areas PA1_2, the second light-emitting areas PA2_2, and the third light-emitting areas PA3_2 of the four second pixels PX2, the areas of the first light-emitting areas PA1_1, the second light-emitting areas PA2_1, and the third light-emitting areas PA3_1 of the first pixel PX1, which has a quadrilateral shape, can be increased.

[0157] The second pixel PX2 may include a plurality of first sub-pixels SPX1 and a plurality of second sub-pixels SPX2. The first sub-pixels SPX1 and the second sub-pixels SPX2 may be arranged alternately in a first direction DR1. Furthermore, the first sub-pixels SPX1 and the second sub-pixels SPX2 may be arranged alternately in a second direction DR2.

[0158] Each first sub-pixel SPX1 may include a first light-emitting region PA1_2 and a second light-emitting region PA2_2. In each first sub-pixel SPX1, the first light-emitting region PA1_2 and the second light-emitting region PA2_2 may be arranged in the order of the first light-emitting region PA1_2 and the second light-emitting region PA2_2 on the first diagonal direction DDR1.

[0159] Each second sub-pixel SPX2 may include a second light-emitting region PA2_2 and a third light-emitting region PA3_2. In each second sub-pixel SPX2, the second light-emitting region PA2_2 and the third light-emitting region PA3_2 may be arranged in the order of the third light-emitting region PA3_2 and the second light-emitting region PA2_2 on the first diagonal direction DDR1.

[0160] The first interval DT1 can be approximately the same as the interval between adjacent light-emitting regions of the first light-emitting region PA1_2, the second light-emitting region PA2_2, and the third light-emitting region PA3_2 that display the same color in the first diagonal direction DDR1. For example, the first interval DT1 can be approximately the same as the first sub-interval DT1_1 between the first light-emitting regions PA1_2 of the first sub-pixel SPX1 that are adjacent to each other (e.g., closest to each other) in the first diagonal direction DDR1. For example, the first interval DT1 can be approximately the same as the interval between adjacent first light-emitting regions PA1_2 that display red.

[0162] Reference Figure 13 The dummy pixel DPX may include a transistor TR and a light-emitting element OLED. The boundary region BA may include a light-emitting region PA and a non-light-emitting region NPA surrounding the light-emitting region PA.

[0163] The second pixel PX2 may include a transistor TR and a light-emitting element OLED. The second display area DA2 may include a light-emitting area PA' and a non-light-emitting area NPA surrounding the light-emitting area PA'. The light-emitting element OLED may be disposed in the light-emitting area PA'. The light-emitting area PA' may be...

[0164] because Figure 13 The cross-sectional configuration of the dummy pixel DPX shown is... Figure 11 The cross-sectional configuration of the first pixel PX1 shown is substantially the same as that of the first pixel PX1; therefore, for ease of explanation, further descriptions of the previously described elements and aspects can be omitted. Furthermore, when viewed in a plane, the cross-sectional configuration of the second pixel PX2 is substantially the same as that of the first pixel PX1, except for the shape of the luminescent region PA'; therefore, for ease of explanation, further descriptions of the previously described elements and aspects can be omitted.

[0165] The pixel limiting layer (PDL) can be disposed between the light-emitting region PA of the dummy pixel DPX and the light-emitting region PA' of the second pixel PX2. That is, the boundary between the dummy pixel DPX and the second pixel PX2 can be defined by the pixel limiting layer (PDL). The hole control layer (HCL), the electron control layer (ECL), and the second electrode (CE) can be disposed on the pixel limiting layer (PDL).

[0167] Apart from Figure 14 , Figure 15 and Figure 16 The first intervals DT11, DT12 and DT13 shown in the figure are different from those in the figure. Figure 12 Outside the first interval DT1 shown, Figure 14 , Figure 15 and Figure 16 It corresponds to Figure 12 The floor plan. Therefore, for ease of explanation, the previous references are omitted. Figure 12 To the extent that the components and technical aspects described are further described, it can be assumed that these components and technical aspects are at least similar to those previously referenced. Figure 12 The corresponding components and technical aspects are described.

[0168] Reference Figure 14 The first interval DT11 can be approximately the same as the interval between adjacent light-emitting areas of the same color in the first light-emitting area PA1_2, the second light-emitting area PA2_2, and the third light-emitting area PA3_2. For example, the first interval DT11 can be approximately the same as the second sub-interval DT1_2 between the second light-emitting areas PA2_2 of the first sub-pixel SPX1 that are adjacent to each other in the first diagonal direction DDR1. That is, the first interval DT11 can be approximately the same as the interval between adjacent second light-emitting areas PA2_2 that display green.

[0169] The second sub-interval DT1_2 can be defined as the interval between the second light-emitting regions PA2_2 of the second sub-pixels SPX2 that are adjacent to each other in the first diagonal direction DDR1.

[0170] Reference Figure 15 The first interval DT12 can be approximately the same as the interval between adjacent light-emitting areas of the same color in the first light-emitting area PA1_2, the second light-emitting area PA2_2, and the third light-emitting area PA3_2. For example, the first interval DT12 can be approximately the same as the third sub-interval DT1_3 between the third light-emitting areas PA3_2 of the second sub-pixels SPX2 that are adjacent to each other in the first diagonal direction DDR1. That is, the first interval DT12 can be approximately the same as the interval between adjacent third light-emitting areas PA3_2 that display blue.

[0171] Reference Figure 16 The first interval DT13 can be greater than the interval between adjacent light-emitting areas of the same color in the first light-emitting area PA1_2, the second light-emitting area PA2_2, and the third light-emitting area PA3_2, and can be less than the second interval DT2. For example, the first interval DT13 can be greater than the first sub-interval DT1_1 between adjacent first light-emitting areas PA1_2 in the first diagonal direction DDR1, and can be less than the second interval DT2.

[0172] However, embodiments of the present invention are not limited thereto. In embodiments, the first interval DT13 may be greater than the second sub-interval DT1_2 between adjacent second light-emitting regions PA2_2 on the first diagonal direction DDR1 (see...). Figure 14 And it can be smaller than the second interval DT2. Furthermore, in an embodiment, the first interval DT13 can be larger than the third sub-interval DT1_3 between adjacent third light-emitting regions PA3_2 on the first diagonal direction DDR1 (see...). Figure 15 And it can be less than the second interval DT2.

[0173] Figure 17 This is a view illustrating the configuration of dummy pixels according to an embodiment of the concept of the present invention.

[0174] Figure 17 It corresponds to Figure 12 Floor plan.

[0175] Reference Figure 17 The dummy pixel DPX_1 can have a configuration substantially the same as the second pixel PX2. For example, the dummy pixel DPX_1 may include a plurality of first sub-pixels SPX1 and second sub-pixels SPX2 arranged alternately in the first direction DR1 and the second direction DR2.

[0176] Each of the first sub-pixels SPX1 of the dummy pixel DPX_1 is arranged on the first diagonal direction DDR1, and may include a first light-emitting area PA1_2 and a second light-emitting area PA2_2 having a rhombus shape. Each of the second sub-pixels SPX2 of the dummy pixel DPX_1 is arranged on the second diagonal direction DDR2, and may include a second light-emitting area PA2_2 and a third light-emitting area PA3_2 having a rhombus shape.

[0177] In an embodiment, similar to the dummy pixel DPX_1, the first pixel PX1 set in the first display area DA1 may also include multiple first sub-pixels SPX1 and second sub-pixels SPX2.

[0178] According to an embodiment of the present invention, since the spacing between the dummy pixels disposed in the boundary region and the second pixels surrounding the boundary region remains consistent along the boundary region, display defects such as banded color spots that may occur in the boundary region between the first display region and the second display region can be prevented or reduced.
