Accordingly, a display device is required to equip with electronic devices such as a camera and a detection sensor (which may also be referred as a light receiving device or sensor).

[0003] Since an electronic device may receive light from the front of a display device, so the electronic device is required to be installed in a location capable of receiving the light. Therefore, in general display devices, a camera (i.e., a camera lens) and a detection sensor are exposed to the front. As a result, a bezel of the display device may become larger or there may be significant limitations in the design of the display device. SUMMARY

[00055] Hereinafter, various embodiments of the disclosure are described in detail with reference to the accompanying drawings .

[00056] FIGS. 1A, IB and IC illustrate a display device 100 according to embodiments of the present disclosure.

[00057] Referring to FIGS. 1A, IB and IC, a display device 100 according to embodiments of the present disclosure may include a display panel 110 which displays an image and one or more electronic devices 11 and 12.

[00058] The display panel 110 may include a display area DA where an image is displayed and a nondisplay area NDA where an image is not displayed. A plurality of subpixels and a plurality of signal lines for driving the plurality of subpixels may be disposed in the display area DA. The non-display area NDA may be an area outside the display area DA. Various signal lines may be disposed in the non-display area NDA, and various driving circuits may be connected to the non-display area NDA. The non-display area NDA may be bent so that it is not visible from the front or may be obscured by a case (not shown) . The non-display area NDA may be also referred as a bezel or a bezel area.

[00059] The display device 100 according to embodiments of the present disclosure may include one or more electronic devices 11 and 12 located below the display panel 110 (i.e., opposite the viewing surface). Here, one or more electronic devices 11 and 12 may be provided separately from the display panel 110.

[00060] One or more electronic devices 11 and 12 may be devices which receive light passing through the display panel 110 and perform a predetermined operation using the received light.

[00061] For example, the one or more electronic devices 11 and 12 may include one or more of a photographing device such as a camera (i.e., image sensor), a detection sensor such as a proximity sensor, and an illuminance sensor. Here, for example, the detection sensor may be an infrared sensor.

[00062] Light required for the operation of one or more electronic devices 11 and 12 may enter the front side (i.e., viewing side) of the display panel 110, pass through the display panel 110, and may be transmitted to one or more electronic devices 11 and 12 located below the display panel 110 (i.e., opposite the viewing surface). For example, light required for the operation of one or more electronic devices 11 and 12 and passing through the display panel 110 may include one or more of visible light, infrared light, and ultraviolet light.

[00063] Referring to FIGS. 1A, IB, and IC, in the display panel 110 according to embodiments of the present disclosure, the display area DA may include a general area NA and one or more optical areas OA1 and OA2. One or more optical areas OA1 and OA2 may be areas which overlap with one or more electronic devices 11 and 12.

[00064] According to the example of FIG. 1A, the display area DA may include a general area NA and a first optical area OA1. Here, at least a portion of the first optical area OA1 may overlap with the first electronic device 11.

[00065] According to the example of FIG. IB, the display area DA may include a general area NA, a first optical area 0A1, and a second optical area 0A2. In the example of FIG. IB, the general area NA may exist between the first optical area OA1 and the second optical area OA2. Here, at least a portion of the first optical area 0A1 may overlap with the first electronic device 11, and at least a portion of the second optical area OA2 may overlap with the second electronic device 12.

[00066] According to the example of FIG. IC, the display area DA may include a general area NA, a first optical area 0A1, and a second optical area 0A2. In the example of FIG. IC, the general area NA may not exist between the first optical area OA1 and the second optical area OA2. That is, the first optical area OA1 and the second optical area OA2 may be in contact with each other. Here, at least a portion of the first optical area 0A1 may overlap with the first electronic device 11, and at least a portion of the second optical area OA2 may overlap with the second electronic device 12.

[00067] One or more optical areas 0A1 and 0A2 are required to include both an image display structure and a light transmission structure. That is, since one or more optical areas OA1 and OA2 are part of the display area DA, light emitting areas of subpixels for image display are required to be disposed in the one or more optical areas 0A1 and OA2 . Additionally, a light transmission structure is required to be formed in one or more optical areas OA1 and OA2 to transmit light to one or more electronic devices 11 and 12.

[00068] One or more electronic devices 11 and 12 may be located behind (i.e., below or opposite to the viewing surface) the display panel 110 and receive light passing through the display panel 110.

[00069] One or more electronic devices 11 and 12 may be not exposed to the front (i.e., viewing side) of the display panel 110. Accordingly, when the user looks at the front of the display device 110, the electronic devices 11 and 12 may be not visible to the user.

[00070] For example, a first electronic device 11 may be a camera which receives light (e.g., visible light) in the visible light wavelength band, and a second electronic device 12 may be a detection sensor such as a proximity sensor or illuminance sensor. For example, the detection sensor may be an infrared sensor for detecting light (e.g., infrared rays) in the infrared wavelength band. Alternatively, the first electronic device 11 may be a detection sensor, and the second electronic device 12 may be a camera.

[00071] Hereinafter, for convenience of explanation, there is exemplified a case in which the first electronic device 11 is a camera and the second electronic device 12 is an infrared-based detection sensor. Here, the camera may be a camera lens or an image sensor.

[00072] In the case that the first electronic device 11 is a camera, the camera may be located behind (i.e., below) the display panel 110, but may be a front camera for photographing the front direction of the display panel 110. Accordingly, the user may view a viewing surface of the display panel 110 and take pictures (self-photographs) using a camera which is not visible to the viewing surface.

[00073] The general area NA and one or more optical areas 0A1 and OA2 included in the display area DA may be areas where an image can be displayed. However, the general area NA may be an area in which a light transmission structure does not need to be formed, and one or more optical areas OA1 and OA2 may be areas in which a light transmission structure is required to be formed.

[00074] Therefore, one or more optical areas OA1 and OA2 are required to have transmittance above a specific level, and the general area NA may not have light transmittance or may have low transmittance below a specific level.

[00075] For example, one or more optical areas OA1 and OA2 and the general area NA may have different resolutions, subpixel arrangement structures, number of subpixels per unit area, electrode structures, line structures, electrode arrangement structures, or line arrangement structures etc.

[00076] For example, the number of subpixels per unit area in one or more optical areas OA1 and 0A2 may be smaller than the number of subpixels per unit area in the general area NA. That is, the resolution of one or more optical areas OA1 and OA2 may be lower than the resolution of the general area NA. Here, the number of subpixels per unit area may mean the same as resolution, pixel density, or pixel integration. For example, a unit of the number of subpixels per unit area may be PPI (Pixels Per Inch) , which means the number of pixels in 1 inch.

[00077] For example, the number of subpixels per unit area in the first optical area OA1 may be less than the number of subpixels per unit area in the general area NA. The number of subpixels per unit area in the second optical area OA2 may be greater than or equal to the number of subpixels per unit area in the first optical area OA1, and may be less than the number of subpixels per unit area in the general area NA.

[00078] Meanwhile, as a method to increase the transmittance of at least one of the first optical area OA1 and the second optical area OA2, there may be applied a differential pixel density design method, as described above. According to the differential pixel density design method, the display panel 110 may be designed so as for the number of subpixels per unit area of at least one of the first optical area OA1 and the second optical area OA2 to be less than the number of subpixels per unit area of the general area NA.

[00079] However, in some cases, a differential pixel size design method may be applied as another method to increase the transmittance of at least one of the first optical area 0A1 and the second optical area OA2. According to the differential pixel size design method, the display panel 110 may be designed so as for the number of subpixels per unit area of at least one of the first optical area OA1 and the second optical area OA2 to be the same as or similar to the number of subpixels per unit area of the general area NA, but for a size of each subpixel SP (i.e., the size of the light emitting area) disposed in at least one of the first optical area OA1 and the second optical area OA2 to be smaller than the size of each subpixel SP (i.e., the size of the light emitting area)placed in the general area NA.

[00080] Hereinafter, for convenience of explanation, it will be described by assuming that the differential pixel density design method is applied among two methods (differential pixel density design method, differential pixel size design method) for increasing the transmittance of at least one of the first optical area OA1 and the second optical area OA2. Accordingly, hereinafter, a small number of subpixels per unit area may be an expression corresponding to a small subpixel size, and a large number of subpixels per unit area may be an expression corresponding to a large subpixel size.

[00081] The first optical area OA1 may have various shapes such as circular, oval, square, hexagon, or octagon. The second optical area OA2 may have various shapes, such as circular, oval, square, hexagon, or octagon. The first optical area OA1 and the second optical area OA2 may have the same shape or different shapes.

[00082] Referring to FIG. IC, in the case that the first optical area 0A1 and the second optical area 0A2 are in contact, the entire optical area including the first optical area OA1 and the second optical area OA2 may also have various shapes, such as circular, oval, square, hexagon, or octagon. Hereinafter, for convenience of explanation, it will be exemplified a case in which each of the first optical area 0A1 and the second optical area 0A2 has a circular shape.

[00083] In the display device 100 according to the embodiments of the present disclosure, if the first electronic device 11, which is not exposed to the outside and is hidden at the bottom of the display panel 100, is a camera, a display device 100 according to embodiments of the present disclosure may be referred as a display device to which UDC (Under Display Camera) technology is applied.

[00084] Accordingly, in the display device 100 according to embodiments of the present disclosure, there may not be required to be formed a notch or camera hole for camera exposure in the display panel 110, so that there is no reduction in area of the display area DA. Accordingly, since a notch or camera hole for camera exposure does not need to be formed in the display panel 110, the size of the bezel area may be reduced, design restrictions may be eliminated, and the degree of freedom in design may be increased.

[00085] In the display device 100 according to embodiments of the present disclosure, although the one or more electronic devices 11 and 12 are hidden behind the display panel 110, the one or more electronic devices 11 and 12 are required to be able to receive light normally and normally perform a designated function thereof.

[00086] In addition, in the display device 100 according to embodiments of the present disclosure, although the one or more electronic devices 11 and 12 are hidden behind the display panel 110 and are located overlapping with the display area DA, there is required that the normal image display function is possible in one or more optical areas OA1 and OA2 overlapping with one or more electronic devices 11 and 12 in the display area DA.

[00087] Since the above-mentioned first optical area OA1 is designed as a transmissive area, a image display characteristics in the first optical area OA1 may be different from those in the general area NA.

[00088] In addition, when designing the first optical area OA1 to improve image display characteristics, there is a possibility that the transmittance of the first optical area OA1 may decrease.

[00089] Therefore, embodiments of the present disclosure may provide a structure of the first optical area OA1 capable of improving the transmittance in the first optical area OA1 while preventing image quality deviation between the first optical area OA1 and the general area NA.

[00090] In addition, embodiments of the present disclosure may provide, for the second optical area OA2 in addition to the first optical area 0A1, a structure of the second optical area OA2 capable of improving the image quality and the transmittance in the second optical area OA2 .

[00091] In addition, in the display device 100 according to embodiments of the present disclosure, the first optical area OA1 and the second optical area OA2 are similar in that they are light-transmission areas, but the usage examples thereof may be different from each other.

[00092] Therefore, in the display device 100 according to embodiments of the present disclosure, the structure of the first optical area OA1 and the structure of the second optical area OA2 are basically similar or the same, but a resolution, a subpixel arrangement structure, the number of subpixels per unit area, a electrode structure, a line structure, a electrode arrangement structure or a line arrangement structure thereof may be different from each other.

[00093] FIG. 2 illustrates a system configuration diagram of a display device 100 according to embodiments of the present disclosure.

[00094] Referring to FIG. 2, the display device 100 may include a display panel 110 and a display driving circuit as components for displaying an image. The display driving circuit may be a circuit for driving the display panel 110, and may include a data driving circuit 220, a gate driving circuit 230 and a display controller 240.

[00095] The display panel 110 may include a display area DA for displaying an image and a non-display area NDA where an image is not displayed. The non-display area NDA may be an area outside the display area DA, and may also be referred to as a bezel area. All or part of the non-display area NDA may be an area visible from the front of the display device 100, or may be an area which is bent and not visible from the front of the display device 100.

[00096] The display panel 110 may include a substrate SUB and a plurality of subpixels SP disposed on the substrate SUB. Additionally, the display panel 110 may further include various types of signal lines to drive the plurality of subpixels SP.

[00097] The display device 100 according to embodiments of the present disclosure may be a liquid crystal display device or the like, or may be a self-luminous display device in which the display panel 110 emits light on its own. When the display device 100 according to embodiments of the present disclosure is a self-luminous display device, each of the plurality of subpixels SP may include a light emitting device. For example, the display device 100 according to embodiments of the present disclosure may be an organic light emitting display device in which a light emitting device is implemented as an organic light emitting diode (OLED). For another example, the display device 100 according to embodiments of the present disclosure may be an inorganic light emitting display device in which the light emitting device is implemented as an inorganic-based light emitting diode. For another example, the display device 100 according to embodiments of the present disclosure may be a quantum dot display device in which a light emitting device is implemented with quantum dots, which are self-luminous semiconductor crystals.

[00098] The structure of each of the plurality of subpixels SP may vary depending on the type of the display device 100. For example, if the display device 100 is a self-luminous display device in which subpixels SP emit light by themselves, each subpixel SP may include a light emitting device emitting light by itself, one or more transistors, and one or more capacitors.

[00099] For example, various types of signal lines may include a plurality of data lines DL transmitting data signals (also called data voltages or image signals) and a plurality of gate lines GL transmitting gate signals (also called scan signals). [000100] The plurality of data lines DL and the plurality of gate lines GL may cross each other. Each of the plurality of data lines DL may be arranged to extend in a first direction. Each of the plurality of gate lines GL may be arranged to extend in a second direction. Here, the first direction may be a column direction and the second direction may be a row direction. Alternatively, the first direction may be a row direction and the second direction may be a column direction. Hereinafter, for convenience of explanation, it will be exemplified a case in which each of the plurality of data lines DL is arranged in a column direction, and each of the plurality of gate lines GL is arranged in a row direction. [000101] The data driving circuit 220 is a circuit for driving a plurality of data lines DL and connecting the the plurality of data lines DL, and may output data signals to the plurality of data lines DL. The gate driving circuit 230 is a circuit for driving a plurality of gate lines GL, and may output gate signals to the plurality of gate lines GL. [000102] The display controller 240 may be a device for controlling the data driving circuit 220 and the gate driving circuit 230, and may control the driving timing for the plurality of data lines DL and the driving timing of the plurality of gate lines GL. [000103] The display controller 240 may supply a data driving control signal DCS to the data driving circuit 220 to control the data driving circuit 220, and may supply a gate driving control signal GCS to the gate driving circuit 230 to control the gate driving circuit 230. [000104] The display controller 240 may receive input image data from a host system 250 and supply image data to the data driving circuit 22 0 based on the input image data. [000105] The data driving circuit 220 may receive image data in digital form from the display controller 240 and convert the received image data into analog data signals to output to a plurality of data ines DL. [000106] The gate driving circuit 230 may receive a first gate voltage corresponding to the turn-on level voltage and a second gate voltage corresponding to the turn-off level voltage along with various gate driving control signals GCS, and may generate gate signals and supply the generated gate signals to the plurality of gate lines GL. [000107] For example, the data driving circuit 220 may be connected to the display panel 110 using a tape automated bonding (TAB) method, or may be connected to the bonding pad of the display panel 110 using a chip-on-glass (COG) or chip-on panel (COP) method, or may be implemented using a chip-on-film (COF) method and connected to the display panel 110. [000108] The gate driving circuit 230 may be connected to the display panel 110 using a tape automated bonding (TAB) method, or may be connected to the bonding pad of the display panel 110 using a chip-on-glass (COG) or chip-on-panel (COP) method, or may be implemented using a chip-on-film (COF) method and connected to the display panel 110. Alternatively, the gate driving circuit 230 may be a gate in panel (GIP) type and may be formed in the non-display area NDA of the display panel 110. The gate driving circuit 230 may be disposed on or connected to the substrate. That is, if the gate driving circuit 230 is a GIP type, the gate driving circuit 230 may be disposed in the non-display area NDA of the substrate. The gate driving circuit 230 may be connected to the substrate if the gate driving circuit 230 is a chip-on-glass (COG) type, a chip-on-film (COF) type, etc. [000109] Meanwhile, at least one of the data driving circuit 220 and the gate driving circuit 230 may be disposed in the display area DA of the display panel 110. For example, at least one of the data driving circuit 220 and the gate driving circuit 230 may be arranged not to overlap the subpixels SP, or may be arranged to partially or entirely overlap with the subpixels SP. [000110] The data driving circuit 220 may be connected to one side (e.g., the upper or lower side) of the display panel 110. Depending on the driving method, panel design method, etc., the data driving circuit 220 may be connected to both sides (e.g., upper and lower sides) of the display panel 110, or may be connected to two or more of the four sides of the display panel 110. [000111] The gate driving circuit 230 may be connected to one side (e.g., left or right side) of the display panel 110. Depending on the driving method, panel design method, etc., the gate driving circuit 230 may be connected to both sides (e.g., left and right side) of the display panel 110, or may be connected to two or more of the four sides of the display panel 110. [000112] The display controller 240 may be implemented as a separate component from the data driving circuit 220, or may be integrated with the data driving circuit 220 and implemented as an integrated circuit. [000113] The display controller 240 may be a timing controller used in typical display technology, or may be a control device capable of further performing other control functions including a timing controller, or may be a control device different from the timing controller, or may be a control device other than a timing controller, or may be a circuit within the control device. The display controller 240 may be implemented with various circuits or electronic components, such as an integrated circuit (IC), a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), or Processor. [000114] The display controller 240 may be mounted on a printed circuit board, a flexible printed circuit, etc., and may be electrically connected to the data driving circuit 220 and the gate driving circuit 230 through a printed circuit board, a flexible printed circuit. [000115] The display controller 240 may transmit and receive signals with the data driving circuit 220 according to one or more predetermined interfaces. For example, the interface may include a low voltage differential signaling (LVDS) interface, an embedded clock point-point interface (EPI), or a serial peripheral interface (SPI). [000116] In order to provide not only an image display function but also a touch sensing function, the display device 100 according to embodiments of the present disclosure may include a touch sensor and a touch sensing circuit for detecting an occurrenace of a touch by a touch object such as a finger or pen or detection a touch position by sensing the touch sensor.

[000118] The touch sensor may include a plurality of touch electrodes. The touch sensor may further include a plurality of touch lines to electrically connect a plurality of touch electrodes and the touch driving circuit 260. [000119] The touch sensor may exist outside the display panel 110 in the form of a touch panel or may exist inside the display panel 110. If the touch sensor exists outside the display panel 110 in the form of a touch panel, the touch sensor may be referred to as an external type. If the touch sensor is an external type, the touch panel and the display panel 110 may be manufactured separately and combined during the assembly process. The external touch panel may include a touch panel substrate and a plurality of touch electrodes on the touch panel substrate. [000120] If the touch sensor exists inside the display panel 110, the touch sensor may be formed on the substrate SUB along with signal lines and electrodes related to display driving during the manufacturing process of the display panel 110. [000121] The touch driving circuit 260 may supply a touch driving signal to at least one of the plurality of touch electrodes and generate touch sensing data by sensing at least one of the plurality of touch electrodes. [000122] The touch sensing circuit may perform touch sensing using a self-capacitance sensing method or a mutual-capacitance sensing method. [000123] If the touch sensing circuit performs touch sensing using a self-capacitance sensing method, the touch sensing circuit may perform touch sensing based on the capacitance between each touch electrode and a touch object (e.g., finger, pen, etc.). According to the selfcapacitance sensing method, each of the plurality of touch electrodes may serve as a driving touch electrode and a sensing touch electrode. The touch driving circuit 260 may drive all or part of the plurality of touch electrodes and sense all or part of the plurality of touch electrodes. [000124] If the touch sensing circuit performs touch sensing using the mutual-capacitance sensing method, the touch sensing circuit may perform touch sensing based on the capacitance between touch electrodes. According to the mutual-capacitance sensing method, the plurality of touch electrodes may be divided into driving touch electrodes and sensing touch electrodes. The touch driving circuit 260 may drive driving touch electrodes and sense sensing touch electrodes. [000125] The touch driving circuit 260 and the touch controller 270 included in the touch sensing circuit may be implemented as separate devices or as one device. Additionally, the touch driving circuit 260 and the data driving circuit 220 may be implemented as separate devices or as one device. [000126] The display device 100 may further include a power supply circuit which supplies various types of power to the display driving circuit and / or the touch sensing circuit. [000127] The display device 100 according to embodiments of the present disclosure may be a mobile terminal such as a smart phone or tablet, or a monitor or television of various sizes, but is not limited thereto, and may be a display of various types and sizes capable of displaying information or images. [000128] As described above, in the display panel 110, the display area DA may include a general area NA and one or more optical areas OA1 and OA2. The general area NA and one or more optical areas OA1 and OA2 may be areas in which images can be displayed. However, the general area NA may be an area in which a light transmission structure does not need to be formed, and the one or more optical areas OA1 and OA2 may be areas in which a light transmission structure needs to be formed. [000129] As described above, the display area DA in the display panel 110 may include one or more optical areas OA1 and OA2 along with the general area NA. However, for convenience of explanation, it is assumed that the display area DA includes both the first optical area OA1 and the second optical area OA2 (FIGS. IB and IC). [000130] FIG. 3 illustrates a display panel 110 according to embodiments of the present disclosure. [000131] Referring to FIG. 3, a plurality of subpixels SP may be disposed in the display area DA of the display panel 110. A plurality of subpixels SP may be disposed in the general area NA, the first optical area OA1, and the second optical area OA2 included in the display area DA. [000132] Referring to FIG. 3, each of the plurality of subpixels SP may include a light emitting device ED and a subpixel circuit SPC configured to drive the light emitting device ED. [000133] Referring to FIG. 3, the subpixel circuit SPC may include a driving transistor DT for driving the light emitting device ED, a scan transistor ST for transferring the data voltage VDATA to the driving transistor DT, and a storage capacitor Cst for maintaining a constant voltage during one frame. [000134] The driving transistor DT may include a first node Nl, a second node N2, and a third node N3. [000135] The first node Nl may be electrically connected to the light emitting device ED. The second node N2 may be connected to the scan transistor ST. The third node N3 may be connected to a driving voltage line VDDL. [000136] The first node Nl may be electrically connected to the pixel electrode PE of the light emitting device ED. The data voltage VDATA may be applied to the second node N2. A driving voltage VDD may be applied to the third node N3. [000137] The first node Nl may be a source node or a drain node, the second node N2 may be a gate node, and the third node N3 may be a drain node or a source node. Hereinafter, for convenience of explanation, in the driving transistor DT, it will be exemplified a case in which the first node Nl is a source node, the second node N2 is a gate node, and the third node N3 is a drain node. [000138] The light emitting device ED may include a pixel electrode PE, an intermediate layer EL, and a common electrode CE. [000139] The pixel electrode PE may be an electrode disposed in each subpixel SP. For example, the pixel electrode PE may be electrically connected directly or indirectly (via another transistor) to the first node N1 of the driving transistor DT of each subpixel SP. [000140] The common electrode CE may be an electrode commonly disposed in the plurality of subpixels SP. For example, the common electrode CE may be electrically connected to a base voltage line VSSL. A base voltage VSS, which is a type of common driving voltage, may be applied to the common electrode CE through the base voltage line VSSL. [000141] For example, the pixel electrode PE may be an anode electrode, and the common electrode CE may be a cathode electrode. Alternatively, the pixel electrode PE may be a cathode electrode, and the common electrode CE may be an anode electrode. Hereinafter, for convenience of explanation, it is assumed that the pixel electrode PE is an anode electrode and the common electrode CE is a cathode electrode. [000142] The intermediate layer EL may include an emission layer EML and a common intermediate layer EL_COM. [000143] For example, the emission layer EML may be disposed in each of the plurality of subpixels SP, or in another example, may be commonly disposed in the plurality of subpixels SP. The common intermediate layer EL COM may be commonly disposed across the plurality of subpixels SP. [000144] The emission layer EML may be disposed in each emission area EA, and the common intermediate layer EL_COM may be commonly disposed across the plurality of emission areas EA and the non-emission area. [000145] The common intermediate layer EL_COM may include a first common intermediate layer COM1 and a second common intermediate layer COM2. The first common intermediate layer COM1 may be disposed between the pixel electrode PE and the emission layer EML, and may include at least one layer (e.g., an organic layer). The second common intermediate layer COM2 may be disposed between the emission layer EML and the common electrode CE, and may include at least one layer (e.g., an organic layer). [000146] For example, the first common intermediate layer COM1 may include a hole injection layer HIL and a hole transfer layer HTL. The second common intermediate layer COM2 may include an electron transport layer ETL, an electron injection layer EIL, and the like. [000147] The hole injection layer may inject holes from the pixel electrode PE to the hole transport layer, the hole transport layer may transport holes to the emission layer EML, and the electron injection layer may inject electrons from the common electrode CE to the electron transport layer, and the electron transport layer may transport electrons to the emission layer EML. [000148] Each light emitting device ED may include an overlapping portion of a pixel electrode PE, an emission layer EML in the intermediate layer EL, and a common electrode CE. A predetermined emission area EA may be formed by each light emitting device ED. For example, the emission area EA may be defined as an area where the pixel electrode PE, the emission layer EML in the intermediate layer EL, and the common electrode CE overlap. [000149] For example, the light emitting device ED may be an organic light emitting diode (OLED) based on organic materials, an inorganic light emitting diode based on inorganic materials, or a quantum dot light emitting device, in the case that the light emitting device ED is an organic light emitting diode, the intermediate layer EL in the light emitting device ED may include an organic layer containing an organic material. [000150] The scan transistor ST may be controlled on-off by a scan signal SC as a type of gate signal applied through the scan signal line SCL as a type of gate line GL, and may be electrically connected between the second node N2 of the driving transistor DT and the data line DL. [000151] The storage capacitor Cst may be electrically connected between the first node N1 and the second node N2 of the driving transistor DT. [000152] The subpixel circuit SPC may have a 2T (Transistor)-IC (Capacitor) structure including two transistors DT and ST and one capacitor Cst, as shown in FIG. 3, and may further include one or more transistors or one or more capacitors in some case. [000153] The storage capacitor Cst may be an external capacitor intentionally designed outside the driving transistor DT rather than a parasitic capacitor (e.g., Cgs, Cgd) as an internal capacitor which may exist between the first node N1 and the second node N2 of the driving transistor DT. Each of the driving transistor DT and scan transistor ST may be an n-type transistor or a p-type transistor. [000154] The circuit elements within each subpixel SP (in particular, light emitting devices EDs implemented with organic light emitting diodes (OLEDs) containing organic materials) may be vulnerable to external moisture or oxygen. Therefore, there may be disposed an encapsulation layer ENCAP on the display panel 110 to prevent oxygen from penetrating into the circuit elements (particularly, the light emitting device ED) . The encapsulation layer ENCAP may be disposed to cover the light emitting devices ED. [000155] Referring to FIG. 3, the display device 100 according to embodiments of the present disclosure may include, in order to sense the user’s touch, a touch sensor layer TSL including a plurality of sensor electrodes, a touch driving circuit 260 configured to sense a plurality of sensor electrodes, and a touch controller 270 configured to determine the presence or absence of a touch or touch coordinates using the sensing result (i.e., touch sensing data) of the touch driving circuit 260. [000156] The touch sensor layer TSL may be embedded into the display panel 110. For example, the touch sensor layer TSL may be disposed on the encapsulation layer ENCAP within the display panel 110. [000157] The display panel 110 may further include a plurality of touch pads TP electrically connected to the touch driving circuit 260, and a plurality of touch routing lines TL for electrically connecting a plurality of sensor electrodes included in the touch sensor layer TSL to a plurality of touch pads TP connected to the touch driving circuit 260. [000158] FIG. 4 illustrates a general area NA, a first optical area 0A1, and a second optical area OA2 in a display panel 110 according to embodiments of the present disclosure. [000159] Referring to FIG. 4, the display panel 110 according to embodiments of the present disclosure may include a display area DA where an image is displayed and a non-display area NDA where an image is not displayed. The display area DA may include a first optical area OA1, a second optical area OA2, and a general area NA. [000160] Since the first optical area 0A1, the second optical area OA2, and the general area NA are included in the display area DA, they may have a display structure. For example, each of the first optical area OA1, the second optical area OA2 and the general area NA may include a plurality of emission areas EA. [000161] In addition, the first optical area OA1 and the second optical area OA2 may be areas through which light can be transmitted, and the general area NA may be an area through which light cannot be transmitted or where light transmission is minimal. The general area NA may refer to an area through which light cannot be transmitted, excluding the first optical area OA1 and the second optical area OA2. Here, the light transmission may mean that light passes between the front and back surfaces of the display panel 110. [000162] The first optical area OA1 may be an area which overlaps with the first electronic device 11. The second optical area OA2 may be an area which overlaps the second electronic device 12. [000163] Each of the first optical area 0A1 and the second optical area OA2 may have a light transmission structure. However, the first optical area OA1 and the second optical area OA2 may have different structural characteristics. For example, the transmittance of the first optical area OA1 may be higher than the transmittance of the second optical area OA2. The resolution or the number of subpixels per unit area of the first optical area OA1 may be lower or smaller than the resolution or the number of subpixels per unit area of the second optical area OA2. [000164] The first electronic device 11 may perform a predetermined operation using light in a first wavelength band among the light passing through the first optical area 0A1. The second electronic device 12 may perform a predetermined operation using light in a second wavelength band different from the first wavelength band among the light transmitting through the second optical area OA2. [000165] The first wavelength band may include one or more of a visible light wavelength band, an infrared wavelength band, and an ultraviolet wavelength band. The second wavelength band includes one or more of a visible light wavelength band, an infrared wavelength band, and an ultraviolet wavelength band, but may be different from the first wavelength band. [000166] For example, the first electronic device 11 may be a camera and the second electronic device 12 may be a detection sensor. The first electronic device 11 may perform a camera operation using light in the visible light wavelength band corresponding to the first wavelength band among the light passing through the first optical area OA1. The second electronic device 12 may perform a sensing operation using light in an infrared wavelength band corresponding to the second wavelength band among the light transmitting through the second optical area OA2 . [000167] Referring to FIG. 4, each of the first optical area OA1 and the second optical area 0A2 may be circular or octagonal. However, the present disclosure is not limited thereto, each of the first optical area OA1 and the second optical area OA2 may have various shapes, such as an elliptical or oval shape, a polygonal shape, or an irregular shape. [000168] The first optical area OA1 and the second optical area OA2 may have the same shape. Alternatively, the first optical area OA1 and the second optical area OA2 may have different shapes. [000169] Referring to FIG. 4, the display area DA may include a plurality of emission areas EA. Since the general area NA, the first optical area OA1 and the second optical area OA2 are areas included in the display area DA, each of the general area NA, first optical area OA1 and second optical area OA2 may include a plurality of emission areas EA. [000170] The plurality of emission areas EA may include emission areas emitting light of three or more colors. For example, the plurality of emission areas EA may include a first color emission area emitting first color light, a second color emission area that emitting second color light, and a third color emission area emitting third color light. [000171] For example, if the first color light is red light, the second color light is green light, and the third color light is blue light, the first color emission area may be referred to as a red emission area EA_R, the second color emission area may be referred to as a green emission area EA_G, and the third color emission area may be referred to as a blue emission area EA_B. [000172] The red emission area EA_R, green emission area EA^G and blue emission area EA^B may have the same size (i.e., emission area size). Alternatively, at least one of the red emission area EA R, green emission area EA_G and blue emission area EA_B may have a size (i.e., emission area size) different from the others. [000173] As described above, the first color, second color, and third color may be different colors, and may be various colors. For example, the first color, second color and third color may be red, green and blue, respectively. Hereinafter, for convenience of explanation, it will be exemplified a case in which the first color is red, the second color is green, and the third color is blue, However, is not limited thereto. [000174] In the case that the first color is red, the second color is green, and the third color is blue, the size of the blue emission area EA^B (i.e., emission area size) may be the largest among the size of the red emission area EA_R (i.e., emission area size), the size of the green emission area EA_G (i.e., emission area size), and the size of the blue emission area EA^B (i.e., emission area size). [000175] The light emitting device ED disposed in the red emission area EA_R may include an emission layer EML emitting red light. The light emitting device ED disposed in the green emission area EA_G may include an emission layer EML emitting green light. The light emitting device ED disposed in the blue emission area EA_B may include an emission layer EML emitting blue light. [000176] Among the emission layer EML emitting red light, the emission layer EML emitting green light, and the emission layer EML emitting blue light, the organic material contained in the emission layer EML emitting blue light may be the most susceptible to material deterioration. Accordingly, by designing the size of the blue emission area EA^B to be the largest, the current density supplied to the light emitting device ED disposed in the blue emission area EA B can be minimal. Therefore, the degree of deterioration of the light emitting device ED disposed in the blue emission area EA_B may become similar to the degree of deterioration of the light emitting device ED disposed in the red emission area EA^R and the light emitting device ED disposed in the green emission area EA_G. [000177] Therefore, there may be eliminated or reduced a deterioration variation between the light emitting device ED disposed in the red emission area EA_R, the light emitting device ED disposed in the green emission area EA_G, and the light emitting device ED disposed in the blue emission area EA_B, thereby improving image quality. [000178] Referring to FIG. 4, each of the plurality of first transmission areas TAI included in the first optical area OA1 may have various shapes such as circular, oval, polygonal, or irregular shapes. Each of the plurality of second transmission areas TA2 included in the second optical area OA2 may have various shapes, such as circular, oval, polygonal, or irregular shapes. [000179] The plurality of first transmission areas TAI may have the same shape. Alternatively, some of the plurality of first transmission areas TAI may have a shape different from the others. The plurality of second transmission areas TA2 may have the same shape. Alternatively, some of the plurality of second transmission areas TA2 may have a different shape from the others. [000180] The first transmission area TAI and the second transmission area TA2 may have the same shape. Alternatively, the first transmission area TAI and the second transmission area TA2 may have different shapes. [000181] Referring to FIG. 4, the general area NA may all correspond to a non-transmission area. That is, the general area NA may include a non-transmission area NTA including a plurality of emission areas EA. That is, the entire general area NA may be a non-transmission area NTA, and the general area NA may not include the transmission area TA. [000182] The first optical area OA1 may further include a non-transmission area NTA including a plurality of emission areas EA and a plurality of first transmission areas TAI. The non-transmission area NTA included in the first optical area OA1 may be an area through which no light is transmitted, or may be an area where light is transmitted with a lower transmittance than the first transmission area TAI. [000183] The second optical area OA2 may further include a non-transmission area NTA including a plurality of emission areas EA, and a plurality of second transmission areas TA2. The non-transmission area NTA included in the second optical area OA2 may be an area through which no light is transmitted, or may be an area through which light is transmitted with a lower transmittance than the second transmission area TA2. [000184] Meanwhile, the common electrode CE may include a plurality of common electrode holes CH corresponding to a plurality of openings. A plurality of common electrode holes CH may be formed in the first optical area OA1 and the second optical area OA2. That is, positions where the plurality of common electrode holes CH are formed may be the first optical area OA1 and the second optical area CA2. [000185] Referring to FIG. 4, the positions where the plurality of common electrode holes CH are formed in the common electrode CE may correspond to the plurality of first transmission areas TAI included in the first optical area OA1, respectively. In addition, positions where the plurality of common electrode holes CH are formed in the common electrode CE may respectively correspond to the plurality of second transmission areas TA2 included in the second optical area OA2. Accordingly, the transmittance of each of the first optical area OA1 and the second optical area OA2 may be improved. [000186] FIG. 5 illustrates signal lines SL arranged on a display panel 110 according to embodiments of the present disclosure. [000187] Referring to FIG. 5, the display panel 110 according to embodiments of the present disclosure may include a plurality of subpixels SP and a plurality of signal lines SL for driving the plurality of subpixels SP) . [000188] Referring to FIG. 5, each of the plurality of subpixels SP may include a light emitting device ED and a subpixel circuit SPC for driving the light emitting device ED. The emission area EA may be formed by the light emitting device ED. [000189] Referring to FIG. 5, the plurality of signal lines SL may supply various driving signals necessary for driving the plurality of subpixels SP to the plurality of subpixels SP. [000190] For example, various driving signals may include a data signal VDATA for driving the data line DL and a scan signal SC for driving the gate line GL. The various driving signals may further include a driving voltage VDD for driving the driving voltage line VDDL and a base voltage VSS for driving the base voltage line VSSL connected to the common electrode CE. [000191] Accordingly, the plurality of signal lines may include a plurality of data lines DL for supplying data signals VDATA and a plurality of gate lines GL for supplying gate signals such as scan signals SC. The plurality of signal lines may further include a driving voltage line VDDL for supplying the driving voltage VDD and a base voltage line VSSL for supplying the base voltage VSS. [000192] Referring to FIG. 5, the display area DA may include a general area NA, a first optical area OA1, and a second optical area OA2. [000193] Referring to FIG. 5, each of the general area NA, the first optical area 0A1 and the second optical area OA2 may include a plurality of emission areas EA. A plurality of light emitting devices ED and a plurality of subpixel circuits SPG may be disposed in each of the general area NA, the first optical area OA1 and the second optical area 0A2. [000194] Referring to FIG. 5, the plurality of signal lines SL may include a plurality of general signal lines SL_NA and a plurality of specific signal lines SL^OA. [000195] The plurality of general signal lines SL NA may be signal lines disposed only in the general area NA without passing through the first optical area OA1 and the second optical area OA2. [000196] The plurality of specific signal lines SL^OA may be signal lines passing through at least one of the first optical area OA1 and the second optical area OA2 . [000197] For example, a plurality of general signal lines SL^NAmay include a plurality of data lines DL^NA and a plurality of gate lines GL_NA which do not pass through the first optical area OA1 and the second optical area OA2 . [000198] For example, a plurality of specific signal lines SL^OA may include a plurality of data lines DL_0A and a plurality of gate lines DL_OA passing through at least one of the first optical area OA1 and the second optical area OA2. [000199] As described above, since the plurality of specific signal lines SL^OA pass through at least one of the first optical area OA1 and the second optical area OA2, the transmission characteristics of the first optical area OA1 and the second optical area OA2 may be influenced by a plurality of specific signal lines SL^OA. [000200] Meanwhile, positions where the plurality of common electrode holes CH are formed in the common electrode CE may respectively correspond to the plurality of first transmission areas TAI included in the first optical area 0A1. In addition, positions where the plurality of common electrode holes CH are formed in the common electrode CE may respectively correspond to the plurality of second transmission areas TA2 included in the second optical area OA2. Accordingly, the transmittance of each of the first optical area 0A1 and the second optical area OA2 may be improved. [000201] In order to further increase the transmittance of the first optical area OA1, when the plurality of specific signal lines SL_OA pass through the first optical area 0A1, the plurality of specific signal lines SL^OA may be arranged to bypass the plurality of common electrode holes CH corresponding to the plurality of first transmission areas TAI. Similarly, in order to further increase the transmittance of the second optical area OA2, when the plurality of specific signal lines SL^OA pass through the second optical area 0A2, the plurality of specific signal lines SL_OA may be arranged to bypass the plurality of common electrode holes CH corresponding to the plurality of second transmission 3I7G8.S TA2 « [000202] In this case, a plurality of specific signal lines SL OA passing through at least one of the first optical area OA1 and the second optical area OA2 may have a line length greater than the plurality of general signal lines SL^NA which do not pass through the first optical area 0A1 and the second optical area 0A2. [000203] Accordingly, the plurality of specific signal lines SL_OA and the plurality of general signal lines SL_NA may have different electrical characteristics (e.g., different line resistance, different signal transmission delays, etc.). As a result, the driving characteristics between the subpixels SP connected to the plurality of specific signal lines SL_OA and the subpixels SP connected to the plurality of general signal lines SL_NA may become different, which may cause deterioration in image quality. [000204] Meanwhile, when manufacturing the display panel 110, there may be performed a process for patterning the common electrode CE having a plurality of common electrode holes CH. In this case, if a change in the patterning process of the common electrode CE occurs, the transmittance of the plurality of common electrode holes CH of the common electrode CE may change, and there may occur the transmittance difference between the plurality of common electrode holes CH. [000205] Accordingly, the display panel 110 according to embodiments of the present disclosure may have a line characteristic deviation reduction structure. [000206] According to the line characteristic deviation reduction structure according to embodiments of the present disclosure, there may be reduced a deviation in electrical characteristics (e.g., deviation in line resistance, deviation in signal transmission delay, etc.) between the plurality of specific signal lines SL_OA passing through at least one of the first optical area OA1 and the second optical area OA2 and the plurality of general signal lines SL_NA which do not pass through the first optical area OA1 and the second optical area OA2. [000207] In addition, the display panel 110 according to embodiments of the present disclosure may have a structure to reduce the range of transmittance variation.

[000310] The amount of infrared rays passing through the optical area OA of the display panel 110 may correspond to an intensity or a value of a point spread function (PSF). Here, the intensity of the point spread function may correspond to the signal intensity of infrared rays during reception processing by the electronic device 800. The intensity of the point spread function may be an indicator of the detection performance of the infrared sensor. [000311] If the metal ratio in the optical area OA increases, that is, if the transmittance of the optical area OA decreases, the intensity of the point spread function, which is an indicator of the detection performance of the infrared sensor, may also decrease. [000312] If the metal ratio in the optical area OA decreases, that is, if the transmittance of the optical area OA increases, the intensity of the point spread function, which is an indicator of the detection performance of the infrared sensor, may also increase. [000313] As another example, in the case that the electronic device 800 is an image sensor or a camera, the performance and quality of the camera operation performed using visible light may vary depending on the amount of visible light passing through the optical area OA of the display panel 110. [000314] The amount of visible light passing through the optical area OA of the display panel 110 may correspond to intensity or a value of a modulation transfer function (MTF). Here, the value of the modulation transfer function may correspond to the signal intensity of visible light during reception processing by the electronic device 800. Here, the value of the modulation transfer function may be an indicator of the camera performance and may indicate the level of sharpness. [000315] If the metal ratio in the optical area OA increases, that is, if the transmittance of the optical area OA decreases, the value of the modulation transfer function, which is a performance indicator of the camera, may also decrease. [000316] If the metal ratio in the optical area OA decreases, that is, if the transmittance of the optical area OA increases, the value of the modulation transfer function, which is a performance indicator of the camera, may increase. [000317] Hereinafter, it will be described a transmittance improvement structure of the optical area OA of the display panel 110 according to embodiments of the present disclosure. The transmittance improvement structure of the optical area OA may include a structure capable of lowering the metal ratio in the optical area OA. [000318] Hereinafter, for convenience of explanation, the optical area OA will be referred to as a first area OA, and the general area NA will be referred to as a second area NA. [000319] FIG. 11 is a plan view of the display panel 110 according to embodiments of the present disclosure. [000320] Referring to FIG. 11, the display panel 110 according to embodiments of the present disclosure may include a substrate SUB including a display area DA capable of displaying an image and a non-display area NDA outside the display area DA, a plurality of subpixels SP included in the display area DA and each including a plurality of light emitting device ED, and a plurality of data lines DL for supplying data signals for image display to a plurality of subpixels SP. [000321] Referring to FIG. 11, the display area DA may include a first area OA capable of transmitting light and a second area NA located outside the first area OA. The second area NA may include an upper area NAI adjacent to an upper edge of the first area OA, and a lower area NA2 adjacent to a lower edge of the first area OA. [000322] In FIG. 11, as an example, the first area OA is indicated by a dotted circle, and an area outside the dotted circle may be the second area NA. The upper area NAI of the second area NA may be an area located at the top of the first area OA among the outer areas of the first area OA. The lower area NA2 of the second area NA may be an area located at the bottom of the first area OA among the outer areas of the first area OA. [000323] Referring to FIG. 11, the plurality of subpixels SP disposed in the display area DA may include first to twelfth subpixels SP1 to SP12. [000324] Referring to FIG. 11, the plurality of subpixels SP disposed in the upper area NAI of the second area NA may include the first subpixel SP1, the second subpixel SP2, and the seventh subpixel SP7, and a tenth subpixel SP10.

[000326] Referring to FIG. 11, the plurality of subpixels SP disposed in the first area OA may include a third subpixel SP3, a fourth subpixel SP4, an eighth subpixel SP8, and an eleventh subpixel SP11. [000327] Referring to FIG. 11, for example, the plurality of subpixels SP disposed in the display area DA may include a red subpixel which emits red light, a green subpixel which emits green light, and a blue subpixel which emits blue light. [000328] Referring to FIG. 11, a plurality of subpixels SP disposed in the display area DA may each include a plurality of pixel electrodes PE. For example, the plurality of pixel electrodes PE may include a red pixel electrode PE(R) included in the red subpixel, a green pixel electrode PE(G) included in the green subpixel, and a blue pixel electrode PE (B) included in the blue subpixel. [000329] Referring to FIG. 11, the plurality of data lines DL disposed in the display area DA may include a red data line DL(R) for supplying data signals to the red subpixel, green data lines DL(G), DL(G)_U and DL(G)_D for supplying data signals to the green subpixels, and a blue data line DL(B) for supplying data signals to the blue subpixel. [000330] Referring to FIG. 11, a plurality of data lines DL disposed in the display area DA may be arranged in the second area NA, which is the general area NA. [000331] Referring to FIG. 11, some (e.g., DL(R), DL(G), DL(B)) of the plurality of data lines DL disposed in the second area NA may pass through a first area OA, which is the optical area OA. [000332] However, other parts (e.g., DL(G)_U and DL(G)_D) of the plurality of data lines DL disposed in the second area NA may be disposed while bypassing the first area OA, which is the optical area OA, without passing through the first area OA. [000333] For example, an upper data line DL(G)_U may be disposed in the upper area NAI of the second area NA, and a lower data line DL(G)_D may be disposed in the lower area NA2 of the second area NA. The upper data line DL(G)_U and the lower data line DL(G)_D may be electrically connected through a bypass line BW which bypasses the first area OA. The upper data line DL(G)_U, the lower data line DL(G)_D, and the bypass line BW may be electrically connected to correspond to a single data line, and this single data line may bypass the first area OA without passing through the first area OA. [000334] For example, referring to FIG. 11, the plurality of data lines DL may include a first data line DL1 passing through all of the upper area NAI, the first area OA, and the lower area NA2. [000335] In the example of FIG. 11, the first data line DL1 may be a green data line DL(G) for supplying a data signal to green subpixels disposed in each of the upper area NAI, the first area OA, and the lower area NA2. However, this is only an example and is not limited thereto.

In this case, the upper data line DL(G)_U, the lower data line DL(G) D and bypass line BW may be electrically connected to serve as a single data line. [000337] In the example of FIG. 11, the upper data line DL(G)_U may be a green data line DL(G)JJ for supplying a data signal to the green subpixel placed in the upper area NAI. In addition, the lower data line DL(G)_D may be a green data line DL(G)_D for supplying a data signal to the green subpixel disposed in the lower area NA2.

[000339] Referring to FIG. 11, the bypass line BW may include a horizontal bypass line H^BW extending in a horizontal direction and a vertical bypass line V_BW extending in a vertical direction, and connecting to the data driving circuit 220. Referring to FIG. 11, the horizontal bypass line H_BW and the upper data line DL(G)_U along with the lower data line DL(G)_D may form a mesh type. [000340] Referring to FIG. 11, crossings between the bypass line BW and the upper data line DL(G) U along with the lower data line DL(G)_D may have connecting points. For example, a first connecting point is formed at a crossing between the upper data line DL(G)JJ and the first bypass line BW1 (which is a horizontal bypass line H_BW), a second connecting point is formed at a crossing between the lower data line DL(G)_D and the second bypass line BW2(which is a horizontal bypass line H^BW), a third connecting point is formed at a crossing between the first bypass line BW1(which is a horizontal bypass line H BW) and the third bypass line BW3(which is a vertical bypass line V_BW), and a fourth connecting point is formed at a crossing between the second bypass line BW2 (which is a horizontal bypass line H_BW)and the third bypass line BW3(which is a vertical bypass line V_BW). [000341] Referring to FIG. 11, the horizontal bypass line H_BW may include a first bypass line BW1 and a second bypass line BW2, and the vertical bypass line V^BW may include a third bypass line BW3. [000342] The horizontal bypass line H_BW and the vertical bypass line V_BW may intersect each other and may overlap with each other in the vertical direction. [000343] Accordingly, the horizontal bypass line H^BW and the vertical bypass line V^BW may be disposed in different metal layers. For example, the horizontal bypass line H BW may be disposed in a first metal layer, and the vertical bypass line V_BW may be disposed in a second metal layer different from the first metal layer. For example, the first metal layer may be a first source-drain metal layer and the second metal layer may be a second source-drain metal layer. [000344] Referring to FIG. 11, the plurality of pixel electrodes PE included in each of the plurality of light emitting device ED may include a first pixel electrode PEI disposed in the upper area NAI and included in the first subpixel SP1, a second pixel electrode PE2 disposed in the upper area NAI and included in the second subpixel SP2, a third pixel electrode PE3 disposed in the first area OA and included in the third subpixel SP3, a fourth pixel electrode PE4 disposed in the first area OA and included in the fourth subpixel SP4, a fifth pixel electrode PE5 disposed in the lower area NA2 and included in the fifth subpixel SP5, and a sixth pixel electrode PE6 disposed in the lower area NA2 and included in the sixth subpixel SP6.

[000346] The first data line DL1 may supply data signals to the first subpixel SP1 in the upper area NAI, the third subpixel SP3 in the first area OA, and the fifth subpixel SP5 in the lower area NA2. [000347] Referring to FIG. 11, the upper data line DL(G)_U may be connected to the second subpixel SP2 disposed in the upper area NAI, and the lower data line DL(G)_D may be connected to the sixth subpixel SP6 disposed in the lower area NA2.

[000352] Referring to FIG. 11, a part (e.g., the third subpixel SP3) of the plurality of subpixels SP3 and SP4 disposed in the first area OA may include the light emitting device ED and the subpixel circuit SPG.

[000355] Referring to FIG. 11, another part (e.g., fourth subpixel SP4) of the plurality of subpixels SP3 and SP4 disposed in the first area OA may include a light emitting device ED, but may not include a subpixel circuit SPG. [000356] Referring to the example of FIG. 11, each of the first subpixel SP1, the second subpixel SP2, the third subpixel SP3, the fifth subpixel SP5, and the sixth subpixel SP6 may include a light emitting device ED and a subpixel circuit PC(G) for driving the light emitting device ED. Here, the subpixel circuit SPC(G) may include two or more transistors DT and ST. [000357] Referring to the example of FIG. 11, the fourth subpixel SP4 may include the light emitting device ED, but may not include the subpixel circuit SPC(G) . The light emitting device ED of the fourth subpixel SP4 may be driven by the subpixel circuit SPC(G) of the third subpixel SP3. [000358] Accordingly, the driving current output from the subpixel circuit SPC(G) of the third subpixel SP3 may be supplied to the third pixel electrode PE3, and may be also supplied to the fourth pixel electrode PE4 through the connection line CW. [000359] Referring to FIG. 11, a plurality of pixel electrodes PE may further include a seventh pixel electrode PE7 disposed in the upper area NAI and included in the seventh subpixel SP7, an eighth pixel electrode PE8 disposed in the first area OA and included in the eighth subpixel SP8, and a ninth pixel electrode PE9 disposed in the lower area NA2 and included in the ninth subpixel SP9.

[000369] For example, the emission color of each of the first subpixel SP1, the second subpixel SP2, the third subpixel SP3, the fourth subpixel SP4, the fifth subpixel SP5 and the sixth subpixel SP6 may be green, and the emission color of each of the tenth subpixel SP10, the eleventh subpixel SP11 and the twelfth subpixel SP12 may be red, however is not limited thereto. [000370] Referring to FIG. 11, the display panel 110 according to embodiments of the present disclosure may further include a common electrode CE disposed on the plurality of pixel electrodes PE. [000371] Referring to FIG. 11, within the first area OA, the common electrode CE may have a plurality of common electrode holes CH. For example, within the first area OA, the common electrode CE may have a common electrode hole CH between the first data line DL1 and the third data line DL3. [000372] The display panel 110 according to embodiments of the present disclosure may include a substrate SUB including a display area DA capable of displaying an image and a non-display area NDA outside the display area DA, a plurality of subpixels SP included in the display area DA and each including a plurality of light emitting devices ED, and a plurality of data lines DL for supplying data signals for image display to a plurality of subpixels SP.

[000374] The second area NA may include an upper area NAI adjacent to an upper edge of the first area OA, and a lower area NA2 adjacent to a lower edge of the first area OA. [000375] The plurality of light emitting devices ED may each include a plurality of pixel electrodes PE. [000376] The plurality of pixel electrodes PE may be disposed in the first area OA, and may include two pixel electrodes PE3 and PE4 which are electrically connected to each other. [000377] The display panel 110 according to embodiments of the present disclosure may be disposed in the first area OA, and may further include a connection line CW which electrically connects the two pixel electrodes PE3 and PE4. [000378] The plurality of data lines DL may include a first data line DL1 connected to one of two subpixels (e.g., a subpixel including PE3) including two pixel electrodes PE3 and PE4. Among the two subpixels containing two pixel electrodes PE3 and PE4, the remaining one (e.g., the subpixel containing PE4) may not connected to the data line. [000379] FIGS. 12 and 13 are plan views of a portion of the first area OA1, which is the optical area OA, of the display panel 110 according to embodiments of the present disclosure. [000380] Referring to FIGS. 12 and 13, the first area OA1, which is the optical area OA of the display panel 110, may include a transmission area TA and a nontransmission area NTA. [000381] Referring to FIGS. 12 and 13, the nontransmission area NTA may include a circuit area CA where a plurality of subpixel circuits, each included in a plurality of subpixels, are disposed. For example, the plurality of subpixel circuits may include a red subpixel circuit included in a red subpixel, a green subpixel circuit included in a green subpixel, and a blue subpixel circuit included in a blue subpixel. [000382] Referring to FIGS. 12 and 13, the nontransmission area NTA may include a plurality of emission areas each corresponding to a plurality of subpixels. Accordingly, a plurality of pixel electrodes PE(R), PE (G) and PE (B) may be disposed in the non-transmission area NTA. [000383] Referring to FIGS. 12 and 13, a plurality of contact holes CNT (R), CNT(G) and CNT(B) may be placed in the non- transmission area NTA for connecting a plurality of pixel electrodes PE(R), PE(G) and PE (B) to a plurality of subpixel circuits, respectively. [000384] For example, a plurality of pixel electrodes PE(R), PE(G) and PE(B) may include a red pixel electrode PE (R) included in the red subpixel, and a green pixel electrodes PE(G) included in the green subpixel, and a blue pixel electrode PE(B) included in the blue subpixel. For reference, the arrangement of the red pixel electrode PE(R), green pixel electrode PE(G) and blue pixel electrode PE(B) in FIGS. 12 and 13 is different from the arrangement of the red pixel electrode PE(R), the green pixel electrode PE(G) and blue pixel electrode PE (B) of FIG. 11. [000385] For example, a plurality of contact holes CNT(R), CNT(G) and CNT(B) may include a contact hole CNT(R) between the red pixel electrode PE(R) and the red subpixel circuit, a contact hole CNT(G) between the green pixel electrode PE(G) and the green subpixel circuit, and a contact hole CNT(B) between the blue pixel electrode PE(B) and the blue subpixel circuit. [000386] Referring to FIGS. 12 and 13, two green pixel electrodes PE(G) may be connected by a connection line CW. The two green pixel electrodes PE(G) connected by the connection line CW may correspond to the third pixel electrode PE3 and the fourth pixel electrode PE4 of FIG. 11 . [000387] Referring to FIGS. 12 and 13, the blue pixel electrode PE(B) may correspond to the eighth pixel electrode PE8 of FIG. 11. [000388] Referring to FIG. 11, in the second area NA which is the general area NA, four data lines (e.g., red data line, green data line, blue data line, green data line) may be arranged repeatedly. [000389] In the upper area NAI of the second area NA which is the general area NA, the red data line DL (R) , the green data line DL(G)_U as the upper data line, and the blue data line DL(B), and the green data line DL (G) may be arranged in order. [000390] Referring to FIG. 11, in the lower area NA2 of the second area NA which is the general area NA, a red data line DL (R) , a green data line DL(G)_D as the lower data line, a blue data line DL (B) , and a green data line DL(G) may be arranged in order. [000391] Referring to FIGS. 12 and 13, in the first area OA which is the optical area OA, three data lines (e.g., red data line DL(R), blue data line DL(B), green data line DL(G)) may be arranged repeatedly. [000392] Referring to FIGS. 12 and 13, in the first area OA, there is omitted a green data line in an area 1200 between the red data line DL(R) and the blue data line DL(B). Accordingly, metal may be reduced within the first area OA which is the optical area OA. As a result, the metal ratio in the first area OA as the optical area OA may be lowered and the transmittance may be increased. [000393] In FIGS. 12 and 13, the green data line DL(G) may correspond to the first data line DL1 in FIG. 11, and the blue data line DL(B) may correspond to the second data line DL2 in FIG 11, and the red data line DL(R) may correspond to the third data line DL3 in FIG. 11. [000394] Referring to FIGS. 12 and 13, the red data line DL (R) , which is the third data line DL3, may overlap the red pixel electrode PE(R). [000395] The area 1200 where the green data line is omitted may be an area immediately adjacent to the red data line DL(R), which is the third data line DL3, and may overlap with the red pixel electrode PE(R). [000396] In the upper area NAI of the second area NA which is the general area NA, the red pixel electrode PE (R) may overlap with two data lines DL (R) and DL(G)_U. In addition, in the lower area NA2 of the second area NA which is the general area NA, the red pixel electrode PE(R) may overlap with two data lines DL(R) and DL(G)_D. [000397] However, as described above, in the first area OA which is the optical area OA, the red pixel electrode PE(R) only overlaps with one data line DL(R). Accordingly, the light emission characteristics of the red subpixel in the first area OA may be different from the light emission characteristics of the red subpixel in the second area NA. [000398] In order to reduce this deviation in light emission characteristics, as shown in FIGS. 12 and 13, the red data line DL(R), which is the third data line DL3, may include a protrusion 1210. The protrusion 1210 may overlap the red pixel electrode PE(R) in the first area OA. [000399] That is, referring to FIGS. 12 and 13, the red data line DL(R), which is the third data line DL3, may overlap with the red subpixel PE(R) which is the eleventh subpixel PE11 of FIG. 11. The red data line DL(R) as the third data line DL3 may include a protrusion 1210 that protrudes into the area 1200 where the green data line is omitted. [000400] The protrusion 1210 may overlap with the red subpixel PE(R) which is the eleventh subpixel PE11 of FIG. 11 in the data line longitudinal direction (i.e., column direction, data line extension direction). [000401] Referring to FIGS. 12 and 13, the third pixel electrode PE3, the connection line CW and the fourth pixel electrode PE4 may be integrally formed. That is, the connection line CW may be composed of a pixel electrode material. [000402] Referring to FIG. 12, in the first area OA, the first data line DL1 and the second data line DL2 may be disposed in the same metal layer (e.g., second metal layer) and spaced apart from each other on the same plane. Similarly, in the second area NA, the first data line DL1 and the second data line DL2 may be disposed in the same metal layer (e.g., second metal layer) and spaced apart from each other on the same plane. [000403] Referring to FIG. 13, in at least a portion of the first area OA, the first data line DL1 and the second data line DL2 may be disposed in the different metal layers (e.g., a first metal layer and a second metal layer) . Alternatively, in the second area NA, the first data line DL1 and the second data line DL2 may be disposed in the same metal layer (e.g., second metal layer). [000404] That is, in the second area NA, the first data line DL1 and the second data line DL2 may be disposed in the same metal layer and spaced apart from each other on the same plane. In the transmission area TA among the transmission area TA and the non-transmission area NTA included in the first area OA, the first data line DL1 and the second data line DL2 may be disposed in different metal layers (e.g., first metal layer, second metal layer), and may overlap in the vertical direction. In the non-transmission area NTA among the transmission area TA and the non-transmission area NTA included in the first area OA, the first data line DL1 and the second data line DL2 may be disposed within the same metal layer (e.g., second metal layer) and spaced apart from each other on the same plane. [000405] Referring to FIG. 13, for example, the first metal layer may be a metal layer between the second interlayer insulating layer 823 and the first planarization layer 831, and may be a first source-drain metal layer. The second metal layer may be a metal layer between the first planarization layer 831 and the second planarization layer 832, and may be a second source-drain metal layer. For example, the blue data line DL(B), which is the second data line DL2, may be disposed in the first metal layer, and the green data line DL(G), which is the first data line DL1, may be disposed in the second metal layer. [000406] FIGS. 14 to 18 are cross-sectional views of the display panel 110 having a transmittance improvement structure according to embodiments of the present disclosure. However, in the cross-sectional views of FIGS. 14 to 18, the stacked structure is the same as that in FIGS. 8 and 9. Therefore, it will be omitted description of the stacked structure. Additionally, in the following description, FIGS. 11 to 13 are also referred to. [000407] FIG. 14 is a cross-sectional view taken along the line X1-X2 of FIGS. 12 and 13, FIG. 15 is a cross-sectional view taken along the line X3-X4 of FIGS. 12 and 13, FIG. 16 is a cross-sectional view taken along the line X5-X6 of FIG. 13, FIG. 17 is a cross-sectional view taken along the line X7-X8 of FIG. 13, and FIG. 18 is a cross-sectional view taken along the line X9-X10 of FIG. 13. [000408] Referring to FIG. 14, in the area indicated by the line X1-X2 of FIGS. 12 and 13, there may be a blue emission area EA_B of the blue subpixel and a red emission area EA_R of the red subpixel. That is, the blue pixel electrode PE(B) and the red pixel electrode PE (R) may be disposed in the area indicated by the line X1-X2 in FIGS. 12 and 13. [000409] Referring to FIG. 14, in the area indicated by the line X1-X2 of FIGS. 12 and 13, there may be disposed a transistor TFT included in the green subpixel circuit SPG (G), a transistor TFT included in the blue subpixel circuit SPC(B), and a transistor TFT included in the red subpixel circuit SPG(R). [000410] These transistors TFT may include a first active layer ACT1 and a first gate electrode GE1 on the first active layer ACT1. The first active layer ACT1 is an active layer of the lower transistor, and may include a silicon-based semiconductor material. For example, the silicon-based semiconductor material may include low-temperature polycrystalline silicon (FTPS). [000411] A shield metal SM which overlaps the first active layer ACT1 may be disposed under the transistors TFT. The shield metal SM may be disposed between the multi-buffer layer 811a and the active buffer layer 811b. [000412] A first upper metal TM1 overlapping with the first gate electrode GE1 may be disposed on the transistors TFT.
