[0044] Description of Reference Numerals DETAILED DESCRIPTION

[0045] In this specification, when a certain component (or region, layer, part, etc.) is mentioned as being "on" another component, "connected" or "combined" with another component, it means that it can be directly arranged on the other component or directly connected / combined with the other component, or a third component may be arranged between them.

[0046] The same reference numerals denote the same components. In addition, in the drawings, the thickness, ratio, and size of the components are exaggerated for the purpose of effectively explaining the technical content.

[0047] "And / or" includes all combinations of more than one that can be defined for the relevant constituent elements.

[0048] Terms such as first and second can be used to describe a variety of components, but the components should not be limited by the terms. The terms are only used to distinguish one component from another. For example, without departing from the scope of the present invention, the first component can be named as the second component, and similarly, the second component can be named as the first component. Singular expressions include plural expressions as long as they do not clearly indicate different meanings in the context.

[0049] Furthermore, terms such as “below,” “lower side,” “above,” and “upper side” are used to describe the relationship between components shown in the drawings. These terms are relative concepts and are described based on the directions shown in the drawings.

[0050] Unless otherwise defined, all terms (including technical and scientific terms) used in this specification have the same meaning as commonly understood by those skilled in the art to which this invention belongs. Furthermore, terms such as those defined in commonly used dictionaries should be interpreted as having meanings consistent with those in the context of the relevant art and may be explicitly defined herein unless they are interpreted as ideal or excessively formal.

[0051] Terms such as "including" or "having" should be understood as intending to specify the existence of the features, numbers, steps, operations, constituent elements, parts or their combinations recorded in the specification, rather than excluding in advance the existence or additional possibility of one or more other features or numbers, steps, operations, constituent elements, parts or their combinations.

[0052] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0053] Figures 1a to 1c is a perspective view of an electronic device according to an embodiment of the present invention. Figure 1a shows the unfolded state (or unfolded state) of the electronic device EDE, Figure 1b The electronic device EDE is shown in the folded state. Figure 1c An electronic device EDE of the strip type is shown.

[0054] Reference Figure 1a and Figure 1b The electronic device EDE according to an embodiment of the present invention may include a display surface DS defined by a first direction DR1 and a second direction DR2 crossing the first direction DR1. The electronic device EDE may provide an image IM to a user through the display surface DS.

[0055] The display surface DS may include a display area DA and a non-display area NDA surrounding the display area DA. The display area DA may display an image IM, while the non-display area NDA may not display an image IM. The non-display area NDA may surround the display area DA. However, this is not limiting, and the shapes of the display area DA and the non-display area NDA may vary.

[0056] Hereinafter, a direction substantially perpendicular to a plane defined by the first direction DR1 and the second direction DR2 is defined as a third direction DR3. In this specification, "on a plane" may be defined as a state viewed from the third direction DR3.

[0057] A sensor area ED-SA may be defined within the display area DA of the electronic device EDE. Figure 1a Although one sensor area ED-SA is shown as an example, the number of sensor areas ED-SA is not limited thereto. The sensor area ED-SA may be part of the display area DA. Therefore, the electronic device EDE may display an image through the sensor area ED-SA.

[0058] An electronic module may be arranged in the area overlapping the sensor area ED-SA. The electronic module may receive external input transmitted through the sensor area ED-SA or provide output through the sensor area ED-SA. For example, the electronic module may be a camera module, a distance sensor such as a proximity sensor, a sensor that recognizes a user's body part (e.g., a fingerprint, iris, or face), or a small light that outputs light, but is not particularly limited to these. The following description uses the example of a camera module as the electronic module overlapping the sensor area ED-SA.

[0059] The electronic device EDE may include a folding area FA and a plurality of non-folding areas NFA1 and NFA2. The non-folding areas NFA1 and NFA2 may include a first non-folding area NFA1 and a second non-folding area NFA2. The folding area FA may be arranged between the first non-folding area NFA1 and the second non-folding area NFA2. The folding area FA may be referred to as a foldable area, and the first non-folding area NFA1 and the second non-folding area NFA2 may be referred to as a first non-foldable area and a second non-foldable area.

[0060] like Figure 1bAs shown, the folding area FA can be folded about a folding axis FX parallel to the first direction DR1. When the electronic device EDE is folded, the folding area FA has a predetermined curvature and radius of curvature. The first non-folding area NFA1 and the second non-folding area NFA2 may face each other, and the electronic device EDE may be inner-folding so that the display surface DS is not exposed to the outside.

[0061] In one embodiment of the present invention, the electronic device EDE can be folded outward (outer-folding) to expose the display surface DS to the outside. In one embodiment of the present invention, the electronic device EDE can be configured to repeatedly perform an unfolding operation, an inner folding operation, or an outer folding operation, but is not limited thereto. In one embodiment of the present invention, the electronic device EDE can be configured to select one of the unfolding operation, the inner folding operation, and the outer folding operation. In one embodiment of the present invention, the electronic device EDE can be defined with multiple folding axes, and an unfolding operation and an inner folding operation or an outer folding operation can be performed along each of the multiple folding axes.

[0062] In addition, if Figure 1c As shown, the electronic device EDE-1 may be a bar-type device that does not include the folding area FA. In this embodiment, the electronic device EDE-1 may provide a planar display area DA having long sides extending along the second direction DR2 and short sides extending along the first direction DR1, and the sensor area ED-SA may be provided on the same display surface as the display area DA.

[0063] In addition, this is merely an exemplary description. The description of the electronic devices EDE and EDE-1 according to an embodiment of the present invention can be applied to various electronic devices such as rollable electronic devices, slidable electronic devices, and stretchable electronic devices, and is not limited to one embodiment.

[0064] Figure 2a is an exploded perspective view of an electronic device according to an embodiment of the present invention. Figure 2b is a block diagram of an electronic device according to an embodiment of the present invention.

[0065] Reference Figure 2a and Figure 2b The electronic device EDE may include a display device DD, a first electronic module EM1, a second electronic module EM2, a power supply module PM, and housings EDC1 and EDC2. The electronic device EDE may also include a device structure for controlling the folding operation of the display device DD.

[0066] The display device DD includes a window module WM and a display module DM. The window module WM provides a front surface of the electronic device EDE. The display module DM may include at least a display panel DP. The display module DM generates an image and senses external input.

[0067] Figure 2a , the display module DM is shown to be the same as the display panel DP, but in practice, the display module DM may be a stacked structure including a plurality of stacked display panels DP. The stacked structure of the display module DM will be described in detail later.

[0068] The display panel DP includes display areas DA ( Figure 1a ) and non-display area NDA ( Figure 1a ) of the display area DP-DA and the non-display area DP-NDA. In this specification, "area / part corresponds to area / part" means overlapping and is not limited to the same area.

[0069] The display area DP-DA may include a first area A1 and a second area A2. The second area A2 may be spaced apart from or adjacent to the first area A1.

[0070] The first area A1 can be aligned with the sensor area ED-SA ( Figure 1a In this embodiment, although the first area A1 is shown as a circle, it can have various shapes such as a polygon, an ellipse, a figure with at least one curved edge, or an irregular shape, and is not limited to one embodiment.

[0071] The first area A1 can be referred to as the component area, and the second area A2 can be referred to as the main display area or the general display area. The first area A1 can have a higher transmittance than the second area A2. Alternatively, the resolution of the first area A1 can be lower than the resolution of the second area A2, but this is not limited to this. For example, the first area A1 can have a higher transmittance than the second area A2, but the resolution of the first area A1 can also be substantially the same as the resolution of the second area A2. The first area A1 can overlap with the camera module CMM described later.

[0072] The display panel DP may include a display layer 100 and a sensor layer 200 .

[0073] The display layer 100 may be a structure that substantially generates an image. The display layer 100 may be a light-emitting display layer, for example, an organic light-emitting display layer, an inorganic light-emitting display layer, an organic-inorganic light-emitting display layer, a quantum dot display layer, a micro-LED display layer, or a nano-LED display layer.

[0074] The sensor layer 200 can sense external input applied from the outside. The external input can be a user input. The user input can include various forms of external input, such as a part of the user's body, light, heat, a pen, or pressure.

[0075] The display module DM may include a driving chip DIC disposed on the non-display area DP-NDA, and may further include a flexible circuit film FCB coupled to the non-display area DP-NDA.

[0076] The driving chip DIC may include driving elements for driving the pixels of the display panel DP, for example, a data driving circuit. Figure 2a The structure in which the driver chip DIC is mounted on the display panel DP is shown, but the present invention is not limited thereto. For example, the driver chip DIC may also be mounted on a flexible circuit film FCB.

[0077] The power supply module PM supplies power required for the overall operation of the electronic device EDE and may include a conventional battery module.

[0078] The first electronic module EM1 and the second electronic module EM2 include various functional modules for operating the electronic device EDE. Each of the first electronic module EM1 and the second electronic module EM2 can be directly mounted on a motherboard electrically connected to the display panel DP, or mounted on a separate substrate and electrically connected to the motherboard via a connector.

[0079] The first electronic module EM1 may include a control module CM, a wireless communication module TM, an image input module IIM, a sound input module AIM, a memory MM, and an external interface IF.

[0080] The control module CM controls the overall operation of the electronic device EDE. The control module CM may be a microprocessor. For example, the control module CM activates or deactivates the display panel DP. The control module CM may also control other modules, such as the image input module IIM or the audio input module AIM, based on touch signals received from the display panel DP.

[0081] The wireless communication module TM can communicate with external electronic devices via a first network (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or IrDA) or a second network (e.g., a long-range communication network such as a cellular network, the Internet, or a computer network (e.g., a LAN or WAN)). The communication modules included in the wireless communication module TM can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module TM can transmit and receive voice signals using a standard communication line. The wireless communication module TM may include a transmitting unit TM1 that modulates and transmits a signal to be transmitted, and a receiving unit TM2 that demodulates a received signal.

[0082] The image input module IIM processes the image signal and converts it into image data that can be displayed on the display panel DP. The audio input module AIM receives external audio signals through a microphone in recording mode, voice recognition mode, etc. and converts them into electrical audio data.

[0083] The external interface IF may include a connector that enables the electronic device EDE to physically connect to an external electronic device. For example, the external interface IF serves as an interface between the control module CM and an external device such as an external charger, a wired / wireless data port, or a card slot (e.g., a memory card, SIM / UIM card).

[0084] The second electronic module EM2 may include an audio output module AOM, a light emitting module LTM, a light receiving module LRM, a camera module CMM, etc. The audio output module AOM converts audio data received from the wireless communication module TM or audio data stored in the memory MM and outputs the converted audio data to the outside.

[0085] The light-emitting module LTM generates and outputs light. The light-emitting module LTM can output infrared light. The light-emitting module LTM may include an LED element. The light-receiving module LRM can sense infrared light. When infrared light above a predetermined level is sensed, the light-receiving module LRM may be activated. The light-receiving module LRM may include a CMOS sensor. After the infrared light generated by the light-emitting module LTM is output, it may be reflected by an external object (e.g., a user's finger or face), and the reflected infrared light may enter the light-receiving module LRM.

[0086] The camera module CMM can capture both still and moving images. Multiple camera modules CMM may be provided. Some of the camera modules CMM may overlap with the first area A1. External input (e.g., light) may be provided to the camera module CMM through the first area A1. For example, the camera module CMM may capture external images by receiving natural light through the first area A1.

[0087] The housings EDC1 and EDC2 house the display module DM, the first and second electronic modules EM1 and EM2, and the power supply module PM. The housings EDC1 and EDC2 protect the display module DM, the first and second electronic modules EM1 and EM2, and the power supply module PM. Figure 2a The two housings EDC1 and EDC2 are shown as being separated from each other, but the present invention is not limited thereto. Although not shown, the electronic device EDE may further include a hinge structure for connecting the two housings EDC1 and EDC2. The housings EDC1 and EDC2 may be combined with the window module WM.

[0088] Figure 3 is a cross-sectional view of a display device according to an embodiment of the present invention. Figure 3 Can be along Figure 2a The sectional view taken along line II' shown in FIG. Figure 3 The present invention will be described.

[0089] The display device DD may include a window module WM and a display module DM. The window module WM may include a window UT, a protection film PF disposed on the window UT, and a bezel pattern BP.

[0090] The window UT may be chemically strengthened glass. When the window UT is applied to the display device DD, wrinkles can be minimized even when repeatedly folded and unfolded. However, this is merely an example. The window UT may be thin-film glass, coated glass, or a flexible film including resin, and is not limited to a single embodiment.

[0091] The protective film PF may include polyimide, polycarbonate, polyamide, triacetylcellulose, polymethylmethacrylate, or polyethylene terephthalate. Although not separately shown, at least one of a hard coat layer, an anti-fingerprint layer, and an anti-reflection layer may be disposed on the protective film PF.

[0092] Border pattern BP and non-display area NDA (refer to Figure 1a The frame pattern BP may be arranged on one surface of the window UT or one surface of the protection film PF. Figure 3 The frame pattern BP is shown as being arranged on the lower surface of the protective film PF. This is not limiting; the frame pattern BP may also be arranged on the upper surface of the protective film PF, the upper surface of the window UT, or the lower surface of the window UT. The frame pattern BP may be a colored light-blocking film, for example, formed by coating. The frame pattern BP may include a base material and a dye or pigment mixed in the base material. The frame pattern BP may have a closed linear shape in a plane.

[0093] A first adhesive layer AL1 may be disposed between the protective film PF and the window UT. The first adhesive layer AL1 may be a pressure-sensitive adhesive film (PSA) or an optically clear adhesive (OCA). The adhesive layer described below may be the same as the first adhesive layer AL1 and may include a conventional adhesive.

[0094] The first adhesive layer AL1 may have a thickness sufficient to cover the bezel pattern BP. The first adhesive layer AL1 may have a thickness sufficient to prevent bubbles from being generated in the periphery of the bezel pattern BP.

[0095] The first adhesive layer AL1 can be separated from the window UT. Since the strength of the protective film PF is lower than that of the window UT, it is relatively easy to be scratched. After the first adhesive layer AL1 and the damaged protective film PF are separated from the window UT, a new protective film PF can be attached to the window UT. Accordingly, the replacement of the protective film PF or the window UT becomes easy. However, this is only an example, and the protective film PF can also be directly formed on the window UT by coating or the like without the first adhesive layer AL1, and can also be omitted, and is not limited to one embodiment.

[0096] The display module DM may include a shock absorbing layer DML, a display panel DP, and a lower part LM.

[0097] The shock absorbing layer DML may be disposed on the display panel DP. The shock absorbing layer DML may be a functional layer for protecting the display panel DP from external impacts. The shock absorbing layer DML may be bonded to the window UT via a second adhesive layer AL2 and to the display panel DP via a third adhesive layer AL3.

[0098] The lower component LM may be arranged below the display panel DP. The lower component LM may include a panel protection layer PPF, a support layer PLT, a cover layer SCV, a digitizer DGZ, a shielding layer MMP, a heat dissipation layer CU, a protective layer PET, and a waterproof tape WFT. In one embodiment of the present invention, the lower component LM may not include some of the above components, or may include other components. In addition, Figure 3 The stacking order shown is merely an example, and the stacking order of each component may be changed.

[0099] The panel protection layer PPF may be disposed below the display panel DP. The panel protection layer PPF may be attached to the back surface of the display panel DP via a fourth adhesive layer AL4. The panel protection layer PPF may protect the lower portion of the display panel DP. The panel protection layer PPF may comprise a flexible plastic material. The panel protection layer PPF may prevent scratches on the back surface of the display panel DP during the manufacturing process of the display panel DP. The panel protection layer PPF may be a colored polyimide film. For example, the panel protection layer PPF may be an opaque yellow film, but is not limited thereto.

[0100] The supporting layer PLT is arranged below the panel protection layer PPF. The supporting layer PLT supports the components arranged on the upper side of the supporting layer PLT and maintains the unfolded state and the folded state of the display device DD. In one embodiment of the present invention, the supporting layer PLT may include at least a first supporting portion corresponding to the first non-folding area NFA1, a second supporting portion corresponding to the second non-folding area NFA2, and a folding portion corresponding to the folding area FA. The first supporting portion and the second supporting portion may be spaced apart from each other in the second direction DR2. The folding portion may be arranged between the first supporting portion and the second supporting portion, and a plurality of opening portions OP may be defined in the folding portion. The opening portion OP may increase the flexibility of a portion of the supporting layer PLT. The opening portion OP may increase the flexibility of a portion of the supporting layer PLT that overlaps with the folding area FA.

[0101] The supporting layer PLT may include carbon fiber reinforced plastic (CFRP), but is not particularly limited thereto. Alternatively, the first supporting portion and the second supporting portion may include non-metallic substances, plastic, glass fiber reinforced plastic, or glass. The plastic may include polyimide, polyethylene, or polyethylene terephthalate, without particular limitation. The first supporting portion and the second supporting portion may include the same substance as each other. The folding portion may include the same substance as the first supporting portion and the second supporting portion, or may include a different substance. For example, the folding portion may include a substance having an elastic modulus of 60 GPa or more, and may include a metal substance such as stainless steel. For example, the folding portion may include SUS304, but is not limited thereto, and the folding portion may include a variety of metal substances.

[0102] The supporting layer PLT can be attached to the panel protection layer PPF via a fifth adhesive layer AL5. Multiple fifth adhesive layers AL5 can be provided, and they can be spaced apart, with the folding area FA positioned therebetween. The fifth adhesive layer AL5 can be non-overlapping with the multiple openings OP. Furthermore, the fifth adhesive layer AL5 can be spaced apart from the multiple openings OP in plan view. By omitting the fifth adhesive layer AL5 in the area corresponding to the folding area FA, the flexibility of the supporting layer PLT can be improved.

[0103] In the area overlapping with the folding area FA, the panel protection layer PPF may be separated from the support layer PLT. That is, in the portion overlapping with the folding area FA, an empty space may be defined between the support layer PLT and the panel protection layer PPF. Since the empty space is defined between the panel protection layer PPF and the support layer PLT, the shapes of the plurality of openings OP defined in the support layer PLT may not be formed in the electronic device EDE ( Figure 1a )'s exterior is seen.

[0104] The thickness of the fifth adhesive layer AL5 may be smaller than that of the fourth adhesive layer AL4. The smaller the thickness of the fifth adhesive layer AL5, the smaller the step difference caused by the fifth adhesive layer AL5. Figure 1a While a smaller step difference can reduce the shape deformation of the stacked structure caused by folding and unfolding, multiple openings OP may become visible, or the fifth adhesive layer AL5 may become separated due to repeated folding. While a thicker fifth adhesive layer AL5 may reduce the visibility of multiple openings OP and improve the reliability of the adhesion to the fifth adhesive layer AL5 despite repeated folding, the step difference may increase. Therefore, the thickness of the fifth adhesive layer AL5 can be selected within an appropriate range, taking into account folding reliability, adhesion reliability, and visibility of multiple openings OP.

[0105] The cover layer SCV may be disposed below the supporting layer PLT. The cover layer SCV may be bonded to the supporting layer PLT via an adhesive member. The cover layer SCV may cover the plurality of openings OP defined in the supporting layer PLT. Thus, the cover layer SCV may prevent foreign matter from entering the plurality of openings OP. The cover layer SCV may have a lower elastic modulus than that of the supporting layer PLT. For example, the cover layer SCV may include, but is not limited to, thermoplastic polyurethane, rubber, or silicone.

[0106] The digitizer DGZ can be arranged below the supporting layer PLT. Multiple digitizers DGZ can be provided. For example, the multiple digitizers DGZ can be spaced apart in the second direction DR2. A portion of each of the multiple digitizers DGZ can overlap with the non-folding areas NFA1 and NFA2, while the remaining portion can overlap with the folding area FA. In plan view, a portion of each of the multiple digitizers DGZ can overlap with a portion of the multiple openings OP.

[0107] Each of the multiple digitizers DGZ may include multiple loop coils that generate a magnetic field at a predetermined resonant frequency with an input device (hereinafter, a pen). The multiple digitizers DGZ may also be referred to as an EMR sensing panel. In one embodiment of the present invention, the multiple digitizers DGZ may be omitted.

[0108] The magnetic field generated by the multiple digitizers (DGZs) is applied to an LC resonance circuit formed by the pen's inductor (coil) and capacitor. The coil, in response to the received magnetic field, generates a current, which it then transfers to the capacitor. The capacitor, in turn, is charged by the current input from the coil and then discharged back to the coil. Ultimately, the coil emits a magnetic field at the resonant frequency. The magnetic field emitted by the pen is then absorbed by the loop coils of the multiple digitizers (DGZs), allowing the position of the pen within the multiple digitizers (DGZs) to be determined.

[0109] Shielding layers MMP may be disposed below each of the digitizers DGZ. Each shielding layer MMP may include magnetic metal powder. The shielding layer MMP may be referred to as a magnetic metal powder layer, a magnetic layer, a magnetic circuit layer, or a magnetic path layer. The shielding layer MMP may shield against magnetic fields.

[0110] The heat dissipation layers CU may be disposed below the shielding layers MMP, respectively. The heat dissipation layers CU may be sheets having high thermal conductivity. For example, each of the heat dissipation layers CU may include graphite, copper, or a copper alloy, but is not limited thereto.

[0111] The protective layer PET can be arranged under the heat dissipation layer CU. The protective layer PET can be an insulating layer. For example, the protective layer PET can be a layer provided to prevent the inflow of static electricity. Therefore, the protective layer PET can prevent the flexible circuit film FCB (refer to Figure 2a ) and the components arranged on the protective layer PET.

[0112] The waterproof tape WFT can be attached to the shielding layer MMP and the protective layer PET. The waterproof tape WFT can also be attached to a complete bracket (not shown). The thickness of the waterproof tape WFT attached to the shielding layer MMP can be different from the thickness of the waterproof tape WFT attached to the protective layer PET.

[0113] A through hole COP may be defined in at least a portion of the components constituting the lower member LM. The through hole COP may be aligned with the sensor area ED-SA (see Figure 1a ) overlap or correspond. Camera module CMM (refer to Figure 2a ) can be inserted into the through hole COP.

[0114] exist Figure 3 The through hole COP is shown as an example, extending from the back surface of one of the protective layers PET to the sixth adhesive layer AL6, but the present invention is not limited thereto. For example, the through hole COP may also extend from the back surface of the one protective layer PET to the top surface of the panel protective layer PPF, or from the back surface of the one protective layer PET to the top surface of the fourth adhesive layer AL4.

[0115] Figure 4 FIG. 4 is a plan view of a display panel according to an embodiment of the present invention. Figure 5 FIG. 1 is an equivalent circuit diagram of a pixel according to an embodiment of the present invention. Figure 4 and Figure 5 , a display panel DP according to an embodiment of the present invention is described.

[0116] Reference Figure 4 The display panel DP may be defined as having a display area DP-DA and a non-display area DP-NDA surrounding the display area DP-DA. The display area DP-DA and the non-display area DP-NDA may be distinguished based on whether pixels PX are arranged therein. Pixels PX are arranged in the display area DP-DA. A scan driver SDV, a data driver, and a light-emitting driver EDV may be arranged in the non-display area DP-NDA. The data driver may be a portion of the circuitry included in the driver chip DIC.

[0117] The display area DP-DA may include a first area A1 and a second area A2. The first area A1 and the second area A2 may be configured based on the arrangement interval of the pixels PX, the size of the pixels PX, the shape of the pixels PX, or whether there is a transmissive area TP (see FIG. Figure 6a ) and are distinguished.

[0118] The display panel DP may include a first panel area AA1, a bending area BA, and a second panel area AA2 defined along a second direction DR2. The second panel area AA2 and the bending area BA may be part of the non-display area DP-NDA. The bending area BA is disposed between the first panel area AA1 and the second panel area AA2.

[0119] The first panel area AA1 is Figure 1a The first panel area AA1 may include a first non-folding area NFA10, a second non-folding area NFA20 and a folding area FA0. The first non-folding area NFA10, the second non-folding area NFA20 and the folding area FA0 are respectively Figure 1a and Figure 1b The first non-folding area NFA1, the second non-folding area NFA2 and the folding area FA correspond to each other.

[0120] The width of the bending area BA and the width (or length) of the second panel area AA2 parallel to the first direction DR1 may be smaller than the width (or length) of the first panel area AA1 parallel to the first direction DR1. The area with a shorter length in the bending axis direction can be bent more easily.

[0121] The display panel DP includes pixels PX, initialization scan lines GIL1-GILm, compensation scan lines GCL1-GCLm, write scan lines GWL1-GWLm, black scan lines GBL1-GBLm, emission control lines ECL1-ECLm, data lines DL1-DLn, first and second control lines CSL1 and CSL2, a driving voltage line PL, and a plurality of pads PD. Here, m and n are natural numbers greater than or equal to 2.

[0122] The pixels PX may be connected to initialization scan lines GIL1 -GILm, compensation scan lines GCL1 -GCLm, write scan lines GWL1 -GWLm, black scan lines GBL1 -GBLm, emission control lines ECL1 -ECLm, and data lines DL1 -DLn.

[0123] The initialization scan lines GIL1-GILm, compensation scan lines GCL1-GCLm, write scan lines GWL1-GWLm, and black scan lines GBL1-GBLm may extend along a first direction DR1 and be electrically connected to the scan driver SDV. The data lines DL1-DLn may extend along a second direction DR2 and may be electrically connected to the driver chip DIC via a bent area BA. The emission control lines ECL1-ECLm may extend parallel to the first direction DR1 and be electrically connected to the emission driver EDV.

[0124] The driving voltage line PL may include a portion extending in a first direction DR1 and a portion extending in a second direction DR2. The portion extending in the first direction DR1 and the portion extending in the second direction DR2 may be arranged on different layers. The portion of the driving voltage line PL extending in the second direction DR2 may extend to the second panel area AA2 via the bending area BA. The driving voltage line PL may provide a driving voltage to the pixel PX.

[0125] The first control line CSL1 is connected to the scan driver SDV and extends toward the lower end of the second panel area AA2 via the bending area BA. The second control line CSL2 is connected to the light emitting driver EDV and extends toward the lower end of the second panel area AA2 via the bending area BA.

[0126] When viewed from a planar perspective, the pad PD may be arranged adjacent to the lower end of the second panel area AA2. The driving chip DIC, the driving voltage line PL, the first control line CSL1, and the second control line CSL2 may be electrically connected to the pad PD. The flexible circuit film FCB may be electrically connected to the pad PD via an anisotropic conductive adhesive layer.

[0127] Figure 5 A plurality of pixels PX (see Figure 4 ). Since each of the plurality of pixels PX has the same circuit structure, only the circuit structure of the pixel PXij will be described, and detailed descriptions of the remaining pixels PX will be omitted.

[0128] Reference Figure 4 and Figure 5Pixel PXij is connected to the i-th data line DLi among the data lines DL1-DLn, the j-th initialization scan line GILj among the initialization scan lines GIL1-GILm, the j-th compensation scan line GCLj among the compensation scan lines GCL1-GCLm, the j-th write scan line GWLj among the write scan lines GWL1-GWLm, the j-th black scan line GBLj among the black scan lines GBL1-GBLm, the j-th emission control line ECLj among the emission control lines ECL1-ECLm, the first and second drive voltage lines VL1 and VL2, and the first and second initialization voltage lines VL3 and VL4. i is an integer greater than 1 and less than n, and j is an integer greater than 1 and less than m.

[0129] Pixel PXij includes a light-emitting element ED and a pixel circuit PDC. The light-emitting element ED may be a light-emitting diode. As an example of the present invention, the light-emitting element ED may be an organic light-emitting diode including an organic light-emitting layer, but is not particularly limited to this. The pixel circuit PDC may control the amount of current flowing into the light-emitting element ED in response to a data signal Di. The light-emitting element ED may emit light at a predetermined brightness in response to the amount of current supplied by the pixel circuit PDC. In this specification, the current of a pixel PXij may refer to the amount of current supplied to the light-emitting element ED.

[0130] The pixel circuit PDC may include a first transistor T1 to a seventh transistor T7 and a first capacitor Cst, a second capacitor Cbst and a third capacitor Nbst. According to the present invention, the structure of the pixel circuit PDC is not limited to Figure 5 The embodiment shown. Figure 5 The pixel circuit PDC shown is merely an example, and the configuration of the pixel circuit PDC may be modified and implemented.

[0131] At least one of the first to seventh transistors T1 to T7 may be a transistor having a low-temperature polycrystalline silicon (LTPS) semiconductor layer. At least one of the first to seventh transistors T1 to T7 may be a transistor having an oxide semiconductor layer. For example, the third and fourth transistors T3 and T4 may be oxide semiconductor transistors, and the first, second, fifth, sixth, and seventh transistors T1, T2, T5, T6, and T7 may be LTPS transistors.

[0132] Specifically, the first transistor T1 (or "driving transistor"), which directly affects the brightness of the light-emitting element ED, can be constructed to include a semiconductor layer made of highly reliable polycrystalline silicon, thereby enabling a high-resolution display device. Furthermore, because oxide semiconductors have high carrier mobility and low leakage current, the voltage drop is minimal even when driven for a long time. In other words, even when driven at a low frequency, the color change of the image due to the voltage drop is minimal, enabling low-frequency driving. Thus, oxide semiconductors have the advantage of low leakage current. Therefore, using an oxide semiconductor for at least one of the third transistor T3 and the fourth transistor T4 connected to the gate electrode of the first transistor T1 prevents leakage current that could flow to the gate electrode while reducing power consumption.

[0133] Some of the first to seventh transistors T1 to T7 may be P-type transistors, and the remaining portion may be N-type transistors. For example, the first transistor T1, the second transistor T2, the fifth transistor T5, the sixth transistor T6, and the seventh transistor T7 may be P-type transistors, and the third transistor T3 and the fourth transistor T4 may be N-type transistors.

[0134] The configuration of the pixel circuit PDC according to the present invention is not limited to Figure 5 The embodiment shown. Figure 5 The pixel circuit PDC shown is merely an example, and the configuration of the pixel circuit PDC may be modified. For example, the first transistor T1 to the seventh transistor T7 may all be P-type transistors or N-type transistors. Alternatively, the first transistor T1, the second transistor T2, the fifth transistor T5, and the sixth transistor T6 may be P-type transistors, and the third transistor T3, the fourth transistor T4, and the seventh transistor T7 may also be N-type transistors.

[0135] The jth initialization scan line GILj, the jth compensation scan line GCLj, the jth write scan line GWLj, the jth black scan line GBLj, and the jth emission control line ECLj can transmit the jth initialization scan signal GIj, the jth compensation scan signal GCj, the jth write scan signal GWj, the jth black scan signal GBj, and the jth emission control signal EMj to the pixel PXij, respectively. The i-th data line DLi transmits the i-th data signal to the pixel PXij. The i-th data signal Di can have the same value as that input to the display device DD (refer to Figure 3 ) corresponds to the voltage level of the image data.

[0136] The first driving voltage line VL1 and the second driving voltage line VL2 can transmit the first driving voltage ELVDD and the second driving voltage ELVSS to the pixel PXij, respectively. Furthermore, the first initialization voltage line VL3 and the second initialization voltage line VL4 can transmit the first initialization voltage VINT and the second initialization voltage VAINT to the pixel PXij, respectively.

[0137] The first transistor T1 is connected between a first driving voltage line VL1 receiving a first driving voltage ELVDD and the light-emitting element ED. The first transistor T1 includes a first electrode connected to the first driving voltage line VL1 via a fifth transistor T5, a second electrode connected to a pixel electrode (or "anode") of the light-emitting element ED via a sixth transistor T6, and a third electrode (e.g., a gate electrode) connected to one end of the first capacitor Cst (e.g., a first node N1). The first transistor T1 can receive an i-th data signal Di transmitted by the i-th data line DLi based on the switching operation of the second transistor T2 and supply a driving current to the light-emitting element ED.

[0138] The second transistor T2 is connected between the data line DLi and the first electrode of the first transistor T1. The second transistor T2 includes a first electrode connected to the data line DLi, a second electrode connected to the first electrode of the first transistor T1, and a third electrode (e.g., a gate electrode) connected to the j-th write scan line GWLj. The second transistor T2 can be turned on in response to the j-th write scan signal GWj received via the j-th write scan line GWLj and transmit the i-th data signal Di transmitted from the i-th data line DLi to the first electrode of the first transistor T1. One end of the second capacitor Cbst can be connected to the third electrode of the second transistor T2, and the other end of the second capacitor Cbst can be connected to the first node N1.

[0139] The third transistor T3 is connected between the second electrode of the first transistor T1 and the first node N1. The third transistor T3 includes a first electrode connected to the third electrode of the first transistor T1, a second electrode connected to the second electrode of the first transistor T1, and a third electrode (e.g., a gate electrode) connected to the j-th compensation scan line GCLj. The third transistor T3 can be turned on in response to the j-th compensation scan signal GCj received via the j-th compensation scan line GCLj, and connect the third electrode of the first transistor T1 and the second electrode of the first transistor T1 to each other, thereby diode-connecting the first transistor T1. One end of the third capacitor Nbst can be connected to the third electrode of the third transistor T3, and the other end of the third capacitor Nbst can be connected to the first node N1.

[0140] The fourth transistor T4 is connected between a first initialization voltage line VL3, to which a first initialization voltage VINT is applied, and a first node N1. The fourth transistor T4 includes a first electrode connected to the first initialization voltage line VL3, which transmits the first initialization voltage VINT; a second electrode connected to the first node N1; and a third electrode (e.g., a gate electrode) connected to the j-th initialization scan line GILj. The fourth transistor T4 is turned on in response to a j-th initialization scan signal GIj received via the j-th initialization scan line GILj. The turned-on fourth transistor T4 transmits the first initialization voltage VINT to the first node N1, thereby initializing the potential of the third electrode of the first transistor T1 (i.e., the potential of the first node N1).

[0141] The fifth transistor T5 includes a first electrode connected to the first driving voltage line VL1, a second electrode connected to the first electrode of the first transistor T1, and a third electrode (e.g., a gate electrode) connected to the j-th emission control line ECLj. The sixth transistor T6 includes a first electrode connected to the second electrode of the first transistor T1, a second electrode connected to the pixel electrode of the light-emitting element ED (e.g., the second node N2), and a third electrode (e.g., a gate electrode) connected to the j-th emission control line ECLj.

[0142] The fifth transistor T5 and the sixth transistor T6 are simultaneously turned on according to the j-th emission control signal EMj received via the j-th emission control line ECLj. The first driving voltage ELVDD applied through the turned-on fifth transistor T5 is compensated by the diode-connected first transistor T1 and then transmitted to the light-emitting element ED through the sixth transistor T6.

[0143] The seventh transistor T7 includes a first electrode connected to a second initialization voltage line VL4 transmitting a second initialization voltage VAINT, a second electrode connected to a second electrode (e.g., a second node N2) of the sixth transistor T6, and a third electrode (e.g., a gate electrode) connected to the j-th black scan line GBLj. The second initialization voltage VAINT may have a voltage level lower than or equal to the first initialization voltage VINT.

[0144] One end of the first capacitor Cst is connected to the third electrode of the first transistor T1, and the other end of the first capacitor Cst is connected to the first driving voltage line VL1. The cathode of the light-emitting element ED may be connected to the second driving voltage line VL2 that transmits the second driving voltage ELVSS. The second driving voltage ELVSS may have a voltage level lower than the first driving voltage ELVDD.

[0145] Figure 6a and Figure 6b FIG. 1 is a plan view showing a portion of a display panel according to an embodiment of the present invention. Figure 6a Shown Figure 4 The first area A1 shown, Figure 6b Shown Figure 4 The second area A2 is shown.

[0146] As described above, the display panel DP includes a plurality of pixels PX. The pixels PX may include first pixels PX11, PX12, and PX13 arranged in the first area A1 and second pixels PX21, PX22, and PX23 arranged in the second area A2.

[0147] Reference Figure 6a , the first area A1 may include a transmission area TP. The transmission area TP may be an area having a relatively higher transmittance than the surrounding area. In this embodiment, the transmission area TP may be provided in plurality. The plurality of transmission areas TP may be arranged spaced apart from each other in the first area A1. In this embodiment, each of the transmission areas TP may be defined (provided or formed) by an opening LBL-OP formed in the light blocking layer LBL. The light blocking layer LBL may be a pixel definition film PDL as described below (refer to Figure 7a ), the first lower light blocking layer BML1 (refer to Figure 7a ), split layer 310 (refer to Figure 7a ) at least one of ).

[0148] The shape of each of the transmissive regions TP may not be a circle. For example, the shape of each of the transmissive regions TP may be a shape formed by a closed line, a polygon, an irregular shape including curves and straight lines, or an irregular shape including curves with different curvatures. The shape of each of the transmissive regions TP may have various shapes as long as it is not a circle, and is not limited to one embodiment.

[0149] Furthermore, the shapes of the transmissive regions TP may include at least N different shapes. That is, each transmissive region TP may have one of N shapes, and all N shapes may be arranged within the first area A1. Some of the N shapes may be multiple, while some may be a single (one). That is, within the first area A1, one transmissive region TP may have the same shape as another, or one may have a unique shape. Alternatively, within the first area A1, each transmissive region TP may have a different shape, or may have the same shape as at least one other. When the number of transmissive regions TP arranged in the first area A1 is M, N may be greater than or equal to 4 and less than or equal to M. A detailed description of the transmissive regions TP will be provided later.

[0150] A first pixel unit PXU1 may be disposed in the first area A1. A plurality of first pixel units PXU1 may be provided and disposed between the transmissive regions TP. The first pixel unit PXU1 may include first pixels PX11, PX12, and PX13. The first pixels PX11, PX12, and PX13 may include a 1-1st color pixel PX11, a 1-2nd color pixel PX12, and a 1-3rd color pixel PX13.

[0151] Reference Figure 6b A second pixel unit PXU2 may be arranged in the second area A2. The second pixel unit PXU2 may include a first sub-pixel unit PXU2a and a second sub-pixel unit PXU2b. The first sub-pixel unit PXU2a may include a 2-3rd color pixel PX23 and a 2-2nd color pixel PX22. The second sub-pixel unit PXU2b may include a 2-1st color pixel PX21 and a 2-2nd color pixel PX22.

[0152] The second pixels PX21, PX22, and PX23 may include a 2-1st color pixel PX21, a 2-2nd color pixel PX22, and a 2-3rd color pixel PX23. The 1-1st color pixel PX11 and the 2-1st color pixel PX21 may be red light-emitting pixels, the 1-2nd color pixel PX12 and the 2-2nd color pixel PX22 may be green light-emitting pixels, and the 1-3rd color pixel PX13 and the 2-3rd color pixel PX23 may be blue light-emitting pixels.

[0153] Figure 6a The first pixels PX11, PX12, PX13 and Figure 6b The shape of each of the second pixels PX21, PX22, and PX23 shown in the plane may correspond to the shape of the light emitting region defined in the light emitting element. The light emitting region may be defined by the pixel definition film PDL (refer to Figure 7a ) of the opening PDLop (refer to Figure 7a In this embodiment, the arrangement rule of the first pixels PX11, PX12, and PX13 arranged in the first area A1 or the shape of the light-emitting area defined in each of the first pixels PX11, PX12, and PX13 may be different from the arrangement rule of the second pixels PX21, PX22, and PX23 arranged in the second area A2 or the shape of the light-emitting area defined in each of the second pixels PX21, PX22, and PX23.

[0154] For example, the number of first pixels PX11, PX12, and PX13 arranged within a reference area in first area A1 can be smaller than the number of second pixels PX21, PX22, and PX23 arranged within the reference area in second area A2. Alternatively, the area of ​​first pixels PX11, PX12, and PX13 arranged within the reference area in first area A1 can be smaller than the area of ​​second pixels PX21, PX22, and PX23 arranged within the reference area in second area A2. Therefore, the resolution of first area A1 can be lower than that of second area A2. Therefore, when achieving the same brightness within the reference area, the size of each first pixel PX11, PX12, and PX13, which needs to emit relatively bright light, can be set larger than the size of each second pixel PX21, PX22, and PX23, thereby compensating for the lifespan of the first pixels PX11, PX12, and PX13.

[0155] However, this is merely an exemplary illustration, and in a display panel according to an embodiment of the present invention, the first pixels PX11, PX12, PX13 and the second pixels PX21, PX22, PX23 may also have the same shape or arrangement rule as each other, and are not limited to one embodiment.

[0156] Figure 7a FIG. 1 is a cross-sectional view showing a first region of a display panel according to an embodiment of the present invention. Figure 7b FIG. 1 is a cross-sectional view showing a second region of a display panel according to an embodiment of the present invention.

[0157] Reference Figure 7a and Figure 7b The display panel DP may include a display layer 100 , a sensor layer 200 , and an anti-reflection layer 300 . The display layer 100 may include a substrate layer 110 , a barrier layer 120 , a circuit layer 130 , a device layer 140 , and an encapsulation layer 150 .

[0158] The substrate layer 110 may include first to fourth sub-substrate layers 111 to 114 .

[0159] Each of the first sub-substrate layer 111 and the fourth sub-substrate layer 114 can include at least one of a polyimide resin, an acrylate resin, a methacrylate resin, a polyisoprene resin, a vinyl resin, an epoxy resin, a urethane resin, a cellulose resin, a siloxane resin, a polyamide resin, and a perylene resin. In this specification, a "~~"-based resin indicates a resin including a "~~"-based functional group. For example, each of the first sub-substrate layer 111 and the fourth sub-substrate layer 114 can include polyimide.

[0160] Each of the second sub-base layer 112 and the third sub-base layer 113 may include an inorganic substance. For example, each of the second sub-base layer 112 and the third sub-base layer 113 may include at least one of silicon oxide, silicon nitride, silicon oxynitride, and amorphous silicon. For example, the second sub-base layer 112 may include silicon oxynitride, and the third sub-base layer 113 may include silicon oxide.

[0161] The thickness of the first sub-substrate layer 111 may be greater than that of the fourth sub-substrate layer 114, but is not particularly limited thereto. The thickness of the second sub-substrate layer 112 may be less than that of the third sub-substrate layer 113, but is not particularly limited thereto.

[0162] The barrier layer 120 may be disposed over the base material layer 110. The barrier layer 120 may include a plurality of sub-barrier layers 121, 122, 123, 124, 125, a first lower light-blocking layer BML1, and a second lower light-blocking layer BML2.

[0163] The first lower light-blocking layer BML1 and the second lower light-blocking layer BML2 can be referred to as the first lower layer and the second lower layer, the first lower metal layer and the second lower metal layer, the first lower electrode layer and the second lower electrode layer, the first lower shielding layer and the second lower shielding layer, the first light-blocking layer and the second light-blocking layer, the first metal layer and the second metal layer, the first electrode layer and the second electrode layer, the first shielding layer and the second shielding layer or the first overlapping layer and the second overlapping layer.

[0164] The plurality of sub-barrier layers 121, 122, 123, 124, and 125 may include a first sub-barrier layer 121, a second sub-barrier layer 122, a third sub-barrier layer 123, a fourth sub-barrier layer 124, and a fifth sub-barrier layer 125 stacked sequentially in a direction away from the substrate layer 110. Each of the first to fifth sub-barrier layers 121 to 125 may include an inorganic material. For example, each of the first to fifth sub-barrier layers 121 to 125 may include at least one of silicon oxide, silicon nitride, silicon oxynitride, and amorphous silicon. For example, the first sub-barrier layer 121 may include silicon oxynitride, the second sub-barrier layer 122 may include silicon oxide, the third sub-barrier layer 123 may include amorphous silicon, the fourth sub-barrier layer 124 may include silicon oxide, and the fifth sub-barrier layer 125 may include silicon oxide.

[0165] Among the first to fifth sub-barrier layers 121 to 125, the fifth sub-barrier layer 125 is closest to the circuit layer 130. The fifth sub-barrier layer 125 may be referred to as an upper sub-barrier layer. The thickness STK1 of the fifth sub-barrier layer 125 may be greater than the thickness of each of the first to fourth sub-barrier layers 121 to 124. For example, the thickness STK1 of the fifth sub-barrier layer 125 may be greater than the sum STK2 of the thicknesses of the first to fourth sub-barrier layers 121 to 124.

[0166] The first lower light-blocking layer BML1 may be arranged in the first area A1, and the second lower light-blocking layer BML2 may be arranged in the second area A2. The first lower light-blocking layer BML1 and the second lower light-blocking layer BML2 may be electrically insulated from each other, and different signals may be applied to the first lower light-blocking layer BML1 and the second lower light-blocking layer BML2. For example, a positive voltage having a predetermined voltage level may be applied to the first lower light-blocking layer BML1, and the voltage provided to the pixel circuit PDC (refer to FIG. 1 ) may be applied to the first lower light-blocking layer BML1. Figure 5 ) of the first driving voltage ELVDD (refer to Figure 5 ) is provided to the second lower light-blocking layer BML2.

[0167] The first lower light-blocking layer BML1 and the second lower light-blocking layer BML2 may be disposed on the same layer and may include the same material. For example, the first lower light-blocking layer BML1 and the second lower light-blocking layer BML2 may be disposed between the fourth sub-blocking layer 124 and the fifth sub-blocking layer 125. The first lower light-blocking layer BML1 and the second lower light-blocking layer BML2 may be covered by the fifth sub-blocking layer 125. Since the fifth sub-blocking layer 125 has the thickest thickness among the first to fifth sub-blocking layers 121 to 125, the degree of change in transistor characteristics caused by the voltage supplied to the first and second lower light-blocking layers BML1 and BML2 may be reduced.

[0168] The first lower light-blocking layer BML1 may have a first opening BMop defining the transmissive region TP. When forming the electrode opening CEop in the common electrode CE, the first lower light-blocking layer BML1 may be a pattern that functions as a mask. For example, light irradiated from the back surface of the base layer 110 toward the common electrode CE may pass through the first opening BMop in the first lower light-blocking layer BML1 and reach a portion of each of the common electrode CE and the cover layer CPL. In other words, light passing through the first opening BMop in the first lower light-blocking layer BML1 may remove portions of the common electrode CE and the cover layer CPL. The light may be a laser beam.

[0169] In the first area A1, the area overlapping with the first opening BMop of the first lower light blocking layer BML1 may be defined as a transmission area TP, and the remaining area may be defined as an element area EP. Figure 6a ) may be arranged in the element region EP, and the plurality of first pixels PX11, PX12, and PX13 may be spaced apart from the transmission region TP.

[0170] A buffer layer (BFL) may be disposed above the barrier layer 120. The buffer layer (BFL) may be provided in both the first region (A1) and the second region (A2). The buffer layer (BFL) may prevent metal atoms or impurities from diffusing from the base layer (110) into the first semiconductor pattern. Furthermore, the buffer layer (BFL) may uniformly form the first semiconductor pattern by adjusting the heat supply rate during the crystallization process for forming the first semiconductor pattern.

[0171] The buffer layer BFL may include multiple inorganic layers. For example, the buffer layer BFL may include a first sub-buffer layer comprising silicon nitride and a second sub-buffer layer comprising silicon oxide disposed above the first sub-buffer layer. The buffer layer BFL may not overlap with the transmissive region TP. In other words, an opening corresponding to the transmissive region TP may be defined in the buffer layer BFL. Since the buffer layer BFL is not disposed in the transmissive region TP, the transmittance of the transmissive region TP can be further improved.

[0172] The circuit layer 130 may be disposed over the buffer layer BFL, and the element layer 140 may be disposed over the circuit layer 130 .

[0173] Reference Figure 7a , exemplarily showing the silicon thin film transistor S-TFT and the oxide thin film transistor O-TFT of the first pixel circuit PDC1a. The silicon thin film transistor S-TFT can be Figure 5The oxide thin film transistor O-TFT may be one of the first transistor T1, the second transistor T2, the fifth transistor T5, the sixth transistor T6, and the seventh transistor T7 described in the embodiment of the present invention, and the oxide thin film transistor O-TFT may be one of the third transistor T3 and the fourth transistor T4. For example, the silicon thin film transistor S-TFT may be the first driving transistor T1-1 included in the first pixel circuit PDC1a.

[0174] The first through seventh transistors T1 through T7 included in the first pixel circuit PDC1a may be referred to as first-type transistors. In the first area A1, the first lower light-blocking layer BML1 may overlap the entire first-type transistors. That is, the first lower light-blocking layer BML1 may completely overlap the area where the first pixel circuit PDC1a is disposed. Therefore, the voltage supplied to the first lower light-blocking layer BML1 may be supplied independently of the operation of the first pixel circuit PDC1a.

[0175] Reference Figure 7b , exemplarily showing the silicon thin film transistor S-TFTa and the oxide thin film transistor O-TFTa of the second pixel circuit PDC2. The silicon thin film transistor S-TFTa may be Figure 5 The first transistor T1 described in the figure, the oxide thin film transistor O-TFTa may be one of the third transistor T3 and the fourth transistor T4. For example, the silicon thin film transistor S-TFTa may be the second driving transistor T1-2 included in the second pixel circuit PDC2.

[0176] The first to seventh transistors T1 to T7 included in the second pixel circuit PDC2 can be referred to as second-type transistors. In the second area A2, the second lower light-blocking layer BML2 can overlap with a portion of the second-type transistors and may not overlap with the remaining portion of the second-type transistors. For example, the second lower light-blocking layer BML2 can overlap with a portion of the area where the second pixel circuit PDC2 is arranged, and in particular, can overlap with the second drive transistor T1-2. Therefore, the voltage provided to the second lower light-blocking layer BML2 can be provided synchronously with the operation of the second pixel circuit PDC2.

[0177] Figure 7a and Figure 7bOnly a portion of the first semiconductor pattern arranged above the buffer layer BFL is shown, and the first semiconductor pattern may also be arranged in other areas. The first semiconductor pattern may be arranged in a specific pattern across multiple pixels. The first semiconductor pattern may have different electrical properties depending on whether it is doped. The first semiconductor pattern may include a first region with high conductivity and a second region with low conductivity. The first region may be doped with an N-type dopant or a P-type dopant. A P-type transistor may include a doped region doped with a P-type dopant, and an N-type transistor may include a doped region doped with an N-type dopant. The second region may be a non-doped region, or may be doped at a lower concentration than the first region.

[0178] The conductivity of the first region can be greater than that of the second region, and the first region can essentially function as an electrode or signal line. The second region can essentially correspond to the active region (or channel region) of a transistor. In other words, a portion of the semiconductor pattern can be the active region of the transistor, another portion can be the source region or drain region of the transistor, and yet another portion can be a connecting electrode or connecting signal line.

[0179] The source region SE1, active region AC1, and drain region DE1 of the silicon thin film transistors S-TFT and S-TFTa may be formed using the first semiconductor pattern. The source region SE1 and the drain region DE1 may extend from the active region AC1 in opposite directions in cross section.

[0180] Figure 7b FIG. 4 shows a portion of a connection signal line CSL formed using a first semiconductor pattern. The connection signal line CSL may be connected to a sixth transistor T6 (refer to FIG. Figure 5 ) and the seventh transistor T7 (refer to Figure 5 ) electrical connection.

[0181] The circuit layer 130 may include a plurality of inorganic layers and a plurality of organic layers. In one embodiment, the first to fifth insulating layers 10 to 50 sequentially stacked on the buffer layer BFL may be inorganic layers, and the sixth to eighth insulating layers 60 to 80 may be organic layers.

[0182] The first insulating layer 10 may be disposed above the buffer layer BFL. The first insulating layer 10 may cover the first semiconductor pattern. The first insulating layer 10 may be an inorganic layer and / or an organic layer and may have a single-layer or multi-layer structure. The first insulating layer 10 may include at least one of aluminum oxide, titanium oxide, silicon oxide, silicon nitride, silicon oxynitride, zirconium oxide, and hafnium oxide. In this embodiment, the first insulating layer 10 may be a single-layer silicon oxide layer. Not only the first insulating layer 10, but also the insulating layer of the circuit layer 130 described later may have a single-layer or multi-layer structure.

[0183] The gate electrode GT1 of the silicon thin-film transistors S-TFT and S-TFTa is arranged above the first insulating layer 10. The gate electrode GT1 may be part of a metal pattern. The gate electrode GT1 overlaps the active area AC1. The gate electrode GT1 may function as a mask during the doping process of the first semiconductor pattern. The gate electrode GT1 may include, but is not limited to, titanium, silver, a silver-containing alloy, molybdenum, a molybdenum-containing alloy, aluminum, an aluminum-containing alloy, aluminum nitride, tungsten, tungsten nitride, copper, indium tin oxide, or indium zinc oxide.

[0184] The second insulating layer 20 may be arranged above the first insulating layer 10 and may cover the gate electrode GT1. The second insulating layer 20 may be an inorganic layer and may have a single layer or a multilayer structure. The second insulating layer 20 may include at least one of silicon oxide, silicon nitride, and silicon oxynitride. In this embodiment, the second insulating layer 20 may have a single layer structure including a silicon nitride layer.

[0185] The third insulating layer 30 may be disposed above the second insulating layer 20. The third insulating layer 30 may be an inorganic layer and may have a single layer or a multilayer structure. For example, the third insulating layer 30 may have a multilayer structure including a silicon oxide layer and a silicon nitride layer. A first capacitor Cst (see FIG. 1 ) may be disposed between the second insulating layer 20 and the third insulating layer 30. Figure 5 Also, the other electrode of the first capacitor Cst may be disposed between the first insulating layer 10 and the second insulating layer 20.

[0186] The second semiconductor pattern may be arranged above the third insulating layer 30. The second semiconductor pattern may include an oxide semiconductor. The oxide semiconductor may include a plurality of regions distinguished according to whether the metal oxide is reduced. The region where the metal oxide is reduced (hereinafter referred to as the "reduction region") has higher conductivity than the region where the metal oxide is not reduced (hereinafter referred to as the "non-reduction region"). The reduction region substantially functions as a source region / drain region of a transistor or a signal line. The non-reduction region is substantially equivalent to an active region (or semiconductor region, channel region) of a transistor. In other words, a portion of the second semiconductor pattern may be an active region of a transistor, another portion of the second semiconductor pattern may be a source region / drain region of a transistor, and another portion of the second semiconductor pattern may be a signal transmission region.

[0187] The source region SE2, active region AC2, and drain region DE2 of the oxide thin film transistors O-TFT and O-TFTa may be formed using the second semiconductor pattern. The source region SE2 and the drain region DE2 may extend from the active region AC2 in opposite directions in a cross section.

[0188] The oxide thin film transistor O-TFT arranged in the first area A1 may overlap the first lower light blocking layer BML1. Therefore, light incident from the lower portion of the display panel DP may be blocked by the first lower light blocking layer BML1 and not be provided to the active area AC2 of the oxide thin film transistor O-TFT.

[0189] The oxide thin film transistor O-TFTa disposed in the second area A2 may not overlap with the second lower light blocking layer BML2. Therefore, a layer for blocking light from the lower portion of the oxide thin film transistor O-TFTa may be added. For example, a third lower light blocking layer BML3 may be disposed below the oxide thin film transistor O-TFTa disposed in the second area A2. The third lower light blocking layer BML3 may be disposed between the second insulating layer 20 and the third insulating layer 30. The third lower light blocking layer BML3 may include a first capacitor Cst (refer to FIG. 1 ). Figure 5 ) is made of the same material as an electrode Csta and can be formed by the same process.

[0190] The fourth insulating layer 40 may be disposed over the third insulating layer 30. The fourth insulating layer 40 may cover the second semiconductor pattern. The fourth insulating layer 40 may be an inorganic layer and may have a single-layer or multi-layer structure. The fourth insulating layer 40 may include at least one of aluminum oxide, titanium oxide, silicon oxide, silicon nitride, silicon oxynitride, zirconium oxide, and hafnium oxide. In this embodiment, the fourth insulating layer 40 may have a single-layer structure including silicon oxide.

[0191] The gate electrodes GT2 of the oxide thin film transistors O-TFT and O-TFTa are arranged above the fourth insulating layer 40. The gate electrode GT2 may be part of the metal pattern. The gate electrode GT2 overlaps with the active area AC2. The gate electrode GT2 may function as a mask during the process of reducing the second semiconductor pattern.

[0192] The fifth insulating layer 50 may be disposed above the fourth insulating layer 40 and may cover the gate electrode GT2. The fifth insulating layer 50 may be an inorganic layer and / or an organic layer and may have a single layer or a multilayer structure. For example, the fifth insulating layer 50 may have a multilayer structure including a silicon oxide layer and a silicon nitride layer.

[0193] The first connection electrode CNE10 may be disposed over the fifth insulating layer 50. The first connection electrode CNE10 may be connected to the connection signal line CSL through a first contact hole CH1 penetrating the first to fifth insulating layers 10 and 50.

[0194] A second opening ILop may be defined in at least a portion of the buffer layer BFL and the plurality of insulating layers 10, 20, 30, 40, 50, 60, 70, and 80 included in the circuit layer 130. For example, a second opening ILop may be defined in the buffer layer BFL and the first to fifth insulating layers 10 to 50. The second opening ILop may be defined in a region overlapping with the transmission region TP. That is, since a portion of each of the buffer layer BFL and the first to fifth insulating layers 10 to 50 overlapping with the transmission region TP is removed, the transmittance of the transmission region TP may be improved.

[0195] The minimum width of the second opening ILop may be smaller than the minimum width of the first opening BMop. Sidewalls of the buffer layer BFL and the first to fifth insulating layers 10 to 50 defining the second opening ILop may protrude further toward the transmission region TP than sidewalls of the first lower light blocking layer BML1.

[0196] A sixth insulating layer 60 may be disposed over the fifth insulating layer 50. The sixth insulating layer 60 may include an organic material and a polyimide resin. For example, the sixth insulating layer 60 may include photosensitive polyimide. A second connection electrode CNE20 may be disposed over the sixth insulating layer 60. The second connection electrode CNE20 may be connected to the first connection electrode CNE10 via a second contact hole CH2 that penetrates the sixth insulating layer 60.

[0197] The sixth insulating layer 60 may be disposed in both the element region EP and the transmission region TP. The sixth insulating layer 60 may be referred to as a common organic layer. The sixth insulating layer 60 may fill the portion where the second opening ILop is defined. That is, the sixth insulating layer 60 may overlap with the transmission region TP. Since the sixth insulating layer 60 is disposed in the transmission region TP, the step difference of the upper surface of the sixth insulating layer 60 may be reduced. When the step difference of the layer overlapping with the transmission region TP is reduced, the diffraction of the light incident on the transmission region TP may be mitigated (or reduced). Therefore, since the deformation of the image caused by diffraction is reduced, the image quality of the camera module CMM ( Figure 2a ) The quality of the image obtained.

[0198] The sixth insulating layer 60 may be formed (or disposed) by removing a portion of the preliminary common organic layer 60-P disposed in the transmission region TP in a thickness direction. Figure 7a In FIG. 5 , the preliminary common organic layer 60 -P is shown by dotted lines, and the removed portion 60 -del is shown by hatched lines. In order to form the sixth insulating layer 60 from the preliminary common organic layer 60 -P, a half-tone mask may be used.

[0199] The first thickness TK1 of the sixth insulating layer 60 in the transmission region TP can be smaller than the second thickness TK2 of the sixth insulating layer 60 in the element region EP. For example, the first thickness TK1 can be the minimum thickness or average thickness of the sixth insulating layer 60 in the transmission region TP, and the second thickness TK2 can be the minimum thickness or average thickness of the sixth insulating layer 60 in the element region EP. The first thickness TK1 can be greater than 40% and less than 100% of the second thickness TK2. The greater the difference between the first thickness TK1 and the second thickness TK2, the greater the step difference of the upper surface of the sixth insulating layer 60. In this case, during the patterning process of the conductive layer closest to the transmission region TP, more conductive layer may be patterned (or removed) than designed. This increases the probability of thinning the line (or wiring), and thus, the probability of defects. As shown in the embodiment of the present invention, setting the first thickness TK1 to greater than 40% of the second thickness TK2 can reduce the probability of defects. Therefore, the transmittance of the transmission region TP may be improved by setting the first thickness TK1 to be 40% or more of the second thickness TK2 , and adverse effects thereby may be minimized.

[0200] For example, if the second thickness TK2 is approximately 15,000 angstroms, the first thickness TK1 may be greater than 6,000 angstroms and less than 10,000 angstroms. If the first thickness TK1 exceeds 10,000 angstroms, the transmittance improvement effect may be reduced. Therefore, the first thickness TK1 may be determined within a range of greater than 40% of the second thickness TK2 and less than 10,000 angstroms.

[0201] The seventh insulating layer 70 may be disposed on the sixth insulating layer 60 and may cover the second connection electrode CNE20 . The eighth insulating layer 80 may be disposed on the seventh insulating layer 70 .

[0202] Each of the sixth insulating layer 60, the seventh insulating layer 70, and the eighth insulating layer 80 may be an organic layer. In this specification, the sixth insulating layer 60 may be referred to as a first organic insulating layer, the seventh insulating layer 70 may be referred to as a second organic insulating layer, and the eighth insulating layer 80 may be referred to as a third organic insulating layer. For example, each of the sixth insulating layer 60, the seventh insulating layer 70, and the eighth insulating layer 80 may include at least one of a general-purpose polymer such as benzocyclobutene (BCB), polyimide, hexamethyldisiloxane (HMDSO), polymethylmethacrylate (PMMA), or polystyrene (PS), a polymer derivative having a phenolic group, an acrylic polymer, an imide polymer, an aryl ether polymer, an amide polymer, a fluorine-based polymer, a paraxylene polymer, a vinyl alcohol polymer, and mixtures thereof.

[0203] Reference Figure 7a and Figure 7b , the element layer 140 can be arranged above the circuit layer 130. The first light-emitting element ED1 may include a pixel electrode AE ​​(or, anode or first electrode), a first functional layer HFL, a light-emitting layer EL, a second functional layer EFL and a common electrode CE (or, cathode or second electrode). The second region light-emitting element ED2a2 may include a pixel electrode AE-1, a first functional layer HFL, a light-emitting layer EL, a second functional layer EFL and a common electrode CE (or, cathode). The first functional layer HFL, the second functional layer EFL and the common electrode CE may be provided together in the pixel PX ( Figure 4 ).

[0204] The pixel electrode AE ​​and the connecting pixel electrode AE-1 may be arranged above the eighth insulating layer 80. The connecting pixel electrode AE-1 may be connected to the second connecting electrode CNE20 via a third contact hole CH3 that penetrates the seventh insulating layer 70 and the eighth insulating layer 80. The pixel electrode AE ​​and the connecting pixel electrode AE-1 may be a translucent electrode, a semi-transparent electrode, or a reflective electrode. As one embodiment, the pixel electrode AE ​​and the connecting pixel electrode AE-1 may include a reflective layer formed using silver, magnesium, aluminum, platinum, palladium, gold, nickel, neodymium, iridium, chromium, or compounds thereof, and a transparent or semi-transparent electrode layer formed on the reflective layer. The transparent or semi-transparent electrode layer may include at least one selected from the group consisting of indium tin oxide, indium zinc oxide, indium gallium zinc oxide, zinc oxide, indium oxide, and aluminum-doped zinc oxide. For example, the pixel electrode AE ​​and the connecting pixel electrode AE-1 may include a multilayer structure in which indium tin oxide, silver, and indium tin oxide are stacked in sequence.

[0205] The pixel definition layer (PDL) may be disposed above the eighth insulating layer 80. The pixel definition layer (PDL) may have a light-absorbing property, for example, the pixel definition layer (PDL) may have a black color. The pixel definition layer (PDL) may include a black coloring agent. The black coloring agent may include a black dye or a black pigment. The black coloring agent may include carbon black, a metal such as chromium, or an oxide thereof.

[0206] The pixel definition film PDL may define an opening PDLop that exposes a portion of the pixel electrode AE ​​or the connecting pixel electrode AE-1. Specifically, the pixel definition film PDL may cover the edge of the pixel electrode AE ​​or the connecting pixel electrode AE-1. Furthermore, the pixel definition film PDL may cover the side surface of the eighth insulating layer 80 adjacent to the transmissive region TP. The pixel definition film PDL may be spaced apart from the side surface of the seventh insulating layer 70 adjacent to the transmissive region TP. Therefore, the pixel definition film PDL may stably contact the seventh insulating layer 70 and the eighth insulating layer 80.

[0207] The light-emitting area can be defined by the opening PDLop defined in the pixel definition layer PDL. The opening PDLop can be called a pixel definition opening. The light generated by the first light-emitting element ED1 and the second area light-emitting element ED2a2 can be displayed in the area defined by the opening PDLop.

[0208] The spacer HSPC may be arranged above the pixel definition film PDL. The protruding spacer SPC may be arranged above the spacer HSPC. The spacer HSPC and the protruding spacer SPC may have an integral shape and may be formed using the same material. For example, the spacer HSPC and the protruding spacer SPC may be formed by the same process using a halftone mask. However, this is merely an example and is not limited thereto. For example, the spacer HSPC and the protruding spacer SPC may also include different materials from each other, or may be formed by separate processes.

[0209] The first functional layer HFL may be disposed over the pixel electrode AE, the connecting pixel electrode AE-1, the pixel definition layer PDL, the spacer HSPC, and the protruding spacer SPC. The first functional layer HFL may include a hole transport layer (HTL), a hole injection layer (HIL), or both. The first functional layer HFL may be disposed throughout the first area A1 and the second area A2.

The light-emitting layer EL may include an organic, inorganic, or organic-inorganic material that emits light of a predetermined color. The light-emitting layer EL may be arranged in the first region A1 and the second region A2. The light-emitting layer EL arranged in the first region A1 may be arranged in the element region EP, excluding the transmissive region TP.

[0211] The second functional layer (EFL) may be disposed above the first functional layer (HFL) and may cover the light-emitting layer (EL). The second functional layer (EFL) may include an electron transport layer (ETL), an electron injection layer (EIL), or both.

[0212] The common electrode CE may be disposed above the second functional layer EFL. The common electrode CE may be disposed in the first area A1 and the second area A2. The common electrode CE may define an electrode opening CEop that overlaps with the first opening BMop. The minimum width of the electrode opening CEop may be greater than the minimum width of the first opening BMop of the first lower light-blocking layer BML1.

[0213] The element layer 140 may further include a cover layer CPL disposed above the common electrode CE. The cover layer CPL may improve luminous efficiency through the principle of constructive interference. For example, the cover layer CPL may include a material having a refractive index of 1.6 or greater for light having a wavelength of 589 nm. The cover layer CPL may be an organic cover layer comprising an organic material, an inorganic cover layer comprising an inorganic material, or a composite cover layer comprising both organic and inorganic materials. For example, the cover layer may include a carbocyclic compound, a heterocyclic compound, an amine-containing compound, a porphine derivative, a phthalocyanine derivative, a naphthalocyanine derivative, an alkali metal complex, an alkaline earth metal compound, or any combination thereof. The carbocyclic compound, heterocyclic compound, and amine-containing compound may be selectively substituted with substituents comprising O, N, S, Se, Si, F, Cl, Br, I, or any combination thereof.

[0214] A portion of the cover layer CPL overlapping the electrode opening CEop of the common electrode CE may be removed. By removing a portion of the cover layer CPL including the portion overlapping the transmission area TP and a portion of the common electrode CE, the transmittance of the transmission area TP may be further improved.

[0215] The encapsulation layer 150 may be disposed over the element layer 140. The encapsulation layer 150 may include an inorganic layer 151, an organic layer 152, and an inorganic layer 153 stacked in sequence, but the layers constituting the encapsulation layer 150 are not limited thereto.

[0216] Inorganic layers 151 and 153 protect element layer 140 from moisture and oxygen, while organic layer 152 protects element layer 140 from foreign matter such as dust particles.

The sensor layer 200 may include a sensor substrate layer 210, a first sensor conductive layer 220, a sensor insulating layer 230, a second sensor conductive layer 240, and a sensor cover layer 250.

[0218] The sensor substrate layer 210 may be disposed directly above the display layer 100. The sensor substrate layer 210 may be an inorganic layer including at least one of silicon nitride, silicon oxynitride, and silicon oxide. Alternatively, the sensor substrate layer 210 may be an organic layer including epoxy resin, acrylic resin, or imide resin. The sensor substrate layer 210 may have a single-layer structure or a multi-layer structure stacked along the third direction DR3.

[0219] Each of the first sensor conductive layer 220 and the second sensor conductive layer 240 may have a single-layer structure, or may have a multi-layer structure stacked along the third direction DR3 .

The metal layer may include molybdenum, silver, titanium, copper, aluminum, or alloys thereof. The transparent conductive layer may include a transparent conductive oxide such as indium tin oxide, indium zinc oxide, zinc oxide, or indium zinc tin oxide. In addition, the transparent conductive layer may include a conductive polymer such as PEDOT, metal nanowires, graphene, etc.

[0221] The conductive layer of the multilayer structure may include a metal layer. For example, the metal layer may have a three-layer structure of titanium / aluminum / titanium. The conductive layer of the multilayer structure may include at least one metal layer and at least one transparent conductive layer.

[0222] The sensor insulating layer 230 may be disposed between the first sensor conductive layer 220 and the second sensor conductive layer 240. The sensor insulating layer 230 may include an inorganic film, which may include at least one of aluminum oxide, titanium oxide, silicon oxide, silicon nitride, silicon oxynitride, zirconium oxide, and hafnium oxide.

The second sensor conductive layer 240 may include a conductive pattern. The sensor cover layer 250 may cover the conductive pattern and reduce or eliminate the possibility of damage to the conductive pattern in subsequent processes.

[0225] The sensor cover layer 250 may include an inorganic substance. For example, the sensor cover layer 250 may include silicon nitride, but is not particularly limited thereto.

[0226] The anti-reflection layer 300 may be disposed over the sensor layer 200. The anti-reflection layer 300 may include a partition layer 310, a plurality of color filters 320, and a planarization layer 330. The partition layer 310 and the color filter 320 may not be disposed in the transmission region TP of the first area A1.

[0227] The partition layer 310 can be arranged overlapping the conductive pattern of the second sensor conductive layer 240. The sensor cover layer 250 can be arranged between the partition layer 310 and the second sensor conductive layer 240. The partition layer 310 can prevent external light from being reflected by the second sensor conductive layer 240. The material constituting the partition layer 310 is not particularly limited as long as it absorbs light. As a black layer, in one embodiment, the partition layer 310 can include a black coloring agent. The black coloring agent can include a black dye or a black pigment. The black coloring agent can include carbon black, a metal such as chromium, or an oxide thereof.

[0228] The partition layer 310 may be defined with a plurality of partition openings 310op1 and 310op2 and a transmissive opening 310opt. The plurality of partition openings 310op1 and 310op2 may overlap with the plurality of light-emitting layers EL, respectively. The color filter 320 may be arranged corresponding to the plurality of partition openings 310op1 and 310op2. The color filter 320 may transmit light provided from the light-emitting layer EL overlapping with the color filter 320.

[0229] The transmissive opening 310opt of the partition layer 310 may overlap with the first opening BMop of the first lower light-blocking layer BML1. The minimum width of the transmissive opening 310opt of the partition layer 310 may be substantially the same as the minimum width of the first opening BMop of the first lower light-blocking layer BML1. That is, in the region adjacent to the transmissive region TP, the end of the partition layer 310 may be substantially aligned with the end of the first lower light-blocking layer BML1. In this specification, the phrase "substantially aligned" or "substantially identical" in width, etc., of the various components not only includes situations where the various components are completely aligned or have physically identical dimensions, such as width, but also includes situations where the components are identical in design but identical within a range of process errors.

[0230] In a region adjacent to the transmission region TP, an end of the partition layer 310 may protrude further toward the transmission region TP than an end of the pixel definition film PDL and an end of the common electrode CE.

[0231] The planarization layer 330 may cover the segmentation layer 310 and the color filter 320. The planarization layer 330 may include an organic material and may provide a flat surface on the upper surface of the planarization layer 330. In one embodiment, the planarization layer 330 may also be omitted.

[0232] In one embodiment of the present invention, the anti-reflection layer 300 may include a reflection adjustment layer instead of the color filter 320. For example, Figure 7a and Figure 7b In the display panel shown, the color filter 320 may be omitted, and a reflection adjustment layer may be added in the position where the color filter 320 is omitted. The reflection adjustment layer can selectively absorb light of a portion of the wavelength band of light reflected from within the display panel and / or electronic device, or light incident from outside the display panel and / or electronic device.

[0233] For example, the reflection adjustment layer absorbs light in a first wavelength range of 490 nm to 505 nm and light in a second wavelength range of 585 nm to 600 nm, thereby enabling the transmittance in the first and second wavelength ranges to be set to 40% or less. The reflection adjustment layer can absorb light with wavelengths outside the wavelength ranges of red, green, and blue light emitted from the light-emitting layer EL. In this way, by absorbing light with wavelengths outside the red, green, or blue wavelength ranges emitted from the light-emitting layer EL, the reflection adjustment layer can prevent or minimize a reduction in the brightness of the display panel and / or electronic device. Furthermore, a reduction in the luminous efficiency of the display panel and / or electronic device can be prevented or minimized, and visibility can be improved.

[0234] The reflection adjustment layer can be configured as an organic layer including dyes, pigments, or combinations thereof. The reflection adjustment layer can include tetraazaporphyrin (TAP) compounds, porphyrin compounds, metal porphyrin compounds, oxazine compounds, squarylium compounds, triarylmethane compounds, polymethine compounds, anthraquinone compounds, phthalocyanine compounds, azo compounds, perylene compounds, xanthene compounds, dimethylammonium compounds, dipyrromethene compounds, cyanine compounds, and combinations thereof.

[0235] In one embodiment, the reflection-adjusting layer may have a transmittance of approximately 64% to 72%. The transmittance of the reflection-adjusting layer may be adjusted based on the content of the pigment and / or dye included in the reflection-adjusting layer. The reflection-adjusting layer may overlap with the light-emitting region in a plan view, but may not overlap with the transmissive region TP in a plan view.

[0236] Figure 8a is a plan view showing a portion of a first lower light-blocking layer according to an embodiment of the present invention, Figure 8b is a plan view showing a portion of a second lower light-blocking layer according to an embodiment of the present invention.

[0237] exist Figure 8a The first pixel unit PXU1 overlapping the first lower light blocking layer BML1 is shown by a dotted line. Figure 8bThe first sub-pixel unit PXU2a overlapping the second lower light-blocking layer BML2 is shown in dotted lines. Figure 6b ) and the second lower light-blocking layer BML2 has substantially the same structure as that of the first sub-pixel unit PXU2a and the second lower light-blocking layer BML2, and thus a detailed description thereof will be omitted.

[0238] The first pixel unit PXU1 may include three first pixel circuits PDC1a, PDC1b, and PDC1c, and the first sub-pixel unit PXU2a may include two second pixel circuits PDC2a and PDC2b. Figure 8a and Figure 8b The dashed line areas shown may correspond to areas where the three first pixel circuits PDC1a, PDC1b, and PDC1c and the two second pixel circuits PDC2a and PDC2b are arranged, respectively.

[0239] Reference Figure 8a and Figure 8b , the first lower light-blocking layer BML1 and the second lower light-blocking layer BML2 can be arranged on the same layer and can be formed simultaneously by the same process. As a result, when compared with the process of forming the first lower light-blocking layer and the second lower light-blocking layer formed on different layers, in the process of forming the first lower light-blocking layer BML1 and the second lower light-blocking layer BML2 according to this embodiment, one mask process can be omitted. Therefore, the display panel DP (refer to Figure 7a ) manufacturing process, thereby reducing the manufacturing cost of the display panel DP.

[0240] The first lower light-blocking layer BML1 and the second lower light-blocking layer BML2 may be arranged on Figure 7a and Figure 7b Between the fourth sub-barrier layer 124 and the fifth sub-barrier layer 125 is shown.

[0241] The first lower light-blocking layer BML1 and the second lower light-blocking layer BML2 may be electrically insulated from each other. The first lower light-blocking layer BML1 may be supplied with a positive voltage having a predetermined voltage level, and the second lower light-blocking layer BML2 may be supplied with a power supply voltage provided to the second pixel circuits PDC2a and PDC2b. For example, the second lower light-blocking layer BML2 may be supplied with a first driving voltage ELVDD (refer to FIG. Figure 5 ).

[0242] The first lower light-blocking layer BML1 may overlap the entire region where the first pixel unit PXU1 is arranged. Therefore, the first lower light-blocking layer BML1 may overlap the first pixels PX11, PX12, PX13 (refer to FIG. 1 ) included in the first pixel unit PXU1. Figure 6a). In the first area A1, the first lower light-blocking layer BML1 may overlap the entire first-type transistor included in each of the first pixels PX11, PX12, and PX13. Therefore, the voltage supplied to the first lower light-blocking layer BML1 may be supplied regardless of the operation of the first pixels PX11, PX12, and PX13.

[0243] The second lower light blocking layer BML2 may overlap a portion of the region where the first sub-pixel unit PXU2a is arranged. For example, the first sub-pixel unit PXU2a may include a 2-2nd color pixel PX22 (refer to Figure 6b ) and the 2nd-3rd color pixel PX23 (refer to Figure 6b In the second region A2, the second lower light-blocking layer BML2 may overlap a portion of the second type transistor included in each of the 2-2nd color pixel PX22 and the 2-3rd color pixel PX23. For example, the second lower light-blocking layer BML2 may overlap with the first transistor T1 (refer to Figure 5 Therefore, the voltage supplied to the second lower light-blocking layer BML2 may be supplied in synchronization with the operation of the 2-2nd color pixel PX22 and the 2-3rd color pixel PX23.

[0244] Each of the first lower light-blocking layer BML1 and the second lower light-blocking layer BML2 may have a single-layer structure or a multi-layer structure including a plurality of layers. For example, each of the first lower light-blocking layer BML1 and the second lower light-blocking layer BML2 may have a multi-layer structure in which titanium and molybdenum are sequentially stacked. Figure 7a ) cracks, the first sub-barrier layer 121 to the fourth sub-barrier layer 124 (refer to Figure 7a ) between the particles, thereby providing a path. In this case, hydrogen can flow through the path, and the lower layer comprising titanium can act as a hydrogen adsorbent. Therefore, the probability of transistor defects caused by hydrogen can be reduced. In one embodiment of the present invention, molybdenum can also be replaced by copper. Alternatively, each of the first lower light-blocking layer BML1 and the second lower light-blocking layer BML2 can include molybdenum or copper, but this is not particularly limited to these.

[0245] Figures 9a to 9c 3 is a diagram showing a light-blocking layer in a first region and a light source image captured through the first region. Figure 9a shows a light blocking layer LBL1-E and a light source image IM1-E according to an embodiment of the present invention, Figure 9b shows a light-blocking layer LBL1-C and a light source image IM1-C1 according to Comparative Example 1-1, Figure 9c The light blocking layers LBL1 - C2 and the light source images IM1 - C2 according to the 1st-2nd comparative example are shown.

[0246] The light blocking layer according to an embodiment of the present invention may include a plurality of transmission portions TP1 , and the shape of the transmission portion TP1 may include N shapes different from each other.

[0247] Each of the transmissive portions TP1 may have a shape selected from N different shapes. The N different shapes may include a reference shape and N-1 tilted shapes. Each of the tilted shapes may correspond to a shape obtained by rotating the reference shape by a predetermined tilt angle. That is, when one shape in the transmissive portion TP1 is referred to as a reference shape, within the first area A1, the shape of the transmissive portion TP1 may have the reference shape or a shape rotated by a predetermined tilt angle from the reference shape.

[0248] The reference shape may not be a circle. For example, each of the transmissive portions TP1 may have a shape having L vertices. The shape having L vertices may be an L-gonal shape or an irregular shape that is a mixture of at least one curved line and at least one straight line. L is a natural number greater than or equal to 3.

[0249] The tilt angles may be different from one another and may be an integer multiple of a reference tilt angle. The reference tilt angle may be the minimum value among the tilt angles. The reference tilt angle may be a divisor (or factor) of 360. That is, the reference tilt angle may be a value whose integer multiple is 360 degrees.

[0250] In the first area A1 including M transmissive portions TP1 having N different shapes, the reference tilt angle may be at least 360 / N or less than 360 / N. M may be equal to or greater than N. That is, in the first area A1, there may be one or more reference shapes. The number of each tilt shape may be the same as or less than the number of reference shapes.

[0251] In addition, within the first area A1, N types of shapes may be arranged in a direction in which the inclination angle increases along one direction. One direction is not limited to one embodiment. For example, it may be the first direction, the second direction, or the third direction. Alternatively, it may be an oblique direction or a curved direction. Alternatively, it may be a spiral direction or a zigzag direction. In addition, the N types of shapes may be randomly arranged within the first area A1. For example, the same shapes among the N types of shapes may be arranged adjacent to each other, shapes with relatively small inclination angles may be arranged adjacent to each other, and shapes with relatively large inclination angles may be arranged adjacent to each other. Alternatively, shapes with inclination angles that differ greatly from each other may be arranged adjacent to each other. In a display panel according to one embodiment of the present invention, as long as the different shapes arranged within the first area A1 are included in a number that is similar to each other (for example, the difference in number is 1 or less), the arrangement form may be changed in many ways and is not limited to one embodiment.

[0252] For example, the light-blocking layer LBL1-E according to one embodiment of the present invention includes a plurality of transmissive portions TP1. The transmissive portions TP1 are arranged spaced apart from each other. The transmissive portions TP1 may have a shape of a regular octagon tilted at a predetermined angle. Because the transmissive portions TP1 have shapes rotated at different angles, the positions of specific vertices of the transmissive portions TP1 may be tilted at different angles relative to an imaginary reference line RL. For example, the angles θ11, θ21, θ31, θ41, and θ51 at the second vertex closest to the reference line RL may be different from each other. The difference between the angles θ11, θ21, θ31, θ41, and θ51 may be defined as the aforementioned tilt angle. While the transmissive portions TP1 in the first row on the leftmost side are referred to as the reference shape, the transmissive portions TP1 arranged sequentially along the first direction DR1 may have a shape tilted at 5 degrees. That is, the angle differences among the angles θ11, θ21, θ31, θ41, and θ51 may be the same 5 degrees along the first direction DR1, and may correspond to a case where the transmissive portion TP1 is arranged with the following shapes: a shape obtained by rotating the reference shape counterclockwise by 5 degrees, a shape obtained by rotating the reference shape counterclockwise by 10 degrees, a shape obtained by rotating the reference shape counterclockwise by 15 degrees, and a shape obtained by rotating the reference shape counterclockwise by 20 degrees when moving away from the reference shape along the first direction DR1.

[0253] This is merely an example. In a display panel according to an embodiment of the present invention, the arrangement of the transmissive portions TP1 defined in the light-blocking layer LBL1-E may be modified in various ways. For example, the transmissive portions TP1 may be arranged in a shape inclined 5 degrees along the second direction DR2. Alternatively, the transmissive portions TP1 may be arranged in a shape inclined 5 degrees along an oblique direction. The arrangement of the transmissive portions TP1 is not limited to a specific embodiment such as a spiral, circular, elliptical, or random shape, and may be modified in various ways.

[0254] Reference Figure 9b , in the light blocking layer LBL1-C1 of the comparative embodiment, the shape of each of the transmission parts TPC11 may be all the same. That is, the transmission part TP1 according to the present invention (refer to Figure 9a ) can be obtained by rotating / tilting each of the transmission portions TPC11 of the comparative embodiment at different tilt angles. In the light-blocking layer LBL1-C1 of the comparative embodiment, the included angles θ11c, θ21c, θ31c, θ41c, and θ51c of the transmission portions TPC11 arranged in the first row relative to the reference line RL may be the same, and the tilt angle that is the angular difference between the included angles θ11c, θ21c, θ31c, θ41c, and θ51c may be 0 degrees.

[0255] Compared to the light source image IM1-E captured through the light-blocking layer LBL1-E according to the present invention, the light source image IM1-C1 captured through the light-blocking layer LBL1-C1 of the comparative example exhibits significant light splitting (or flare). Therefore, the display panel according to the present invention, by forming multiple transmissive portions TP1 with different shapes and tilted at different angles in the light-blocking layer LBL1-E, can mitigate light splitting compared to a light-blocking layer LBL1-C1 comprising transmissive portions TPC11 of identical shapes. According to the present invention, by rotating the uniformly arranged transmissive portions TPC11 of identical shapes, the phenomenon of light diffraction in specific directions can be mitigated. This reduces light leakage or light splitting in specific directions, and also reduces distortion in captured images. Consequently, the quality of images captured through the first area A1 can be improved.

[0256] Reference Figure 9cIn the light-blocking layer LBL1-C2 of the comparative example, each of the transmissive portions TPC12 can be circular. The light source image IM1-C2 captured through the light-blocking layer LBL1-C2 of the comparative example exhibits a similar morphology to the light source image IM1-E captured through the light-blocking layer LBL1-E according to the present invention. When the transmissive portions TPC12 are circular, light diffraction in specific directions is minimized and dispersed evenly, thereby achieving an overall improvement in light splitting. According to the present invention, even if the transmissive portion TP1 is formed in a non-circular shape, such as a polygonal or irregular shape with vertices, the light-blocking layer LBL1-E can be formed using a combination of transmissive portions TP1 having various shapes inclined at a predetermined angle, thereby providing a transmissive region with improved light splitting. This ensures improved transmittance while also providing a transmissive region (first region A1) with increased design flexibility for the transmissive portion TP1.

The shape of each transmission portion TP2 may be a shape obtained by rotating a reference shape by a predetermined tilt angle, and the tilt angles may be different from each other.

[0259] Specifically, taking the transmissive portions TP2 arranged along the first direction DR1 as an example, the angles θ12, θ22, θ32, θ42, and θ52 at the first vertices closest to the reference line RL may be different from each other. In other words, the transmissive portions TP2 arranged along the first direction DR1 may have shapes rotated at different inclination angles.

[0260] Reference Figure 10b , in the light blocking layer LBL2-C of the comparative embodiment, the shape of each of the transmission parts TPC2 may be all the same triangular shape. That is, the transmission part TP2 according to the present invention (refer to Figure 10a) can be obtained by rotating / tilting each of the transmission portions TPC2 of the comparative embodiment at different tilt angles. In the light-blocking layer LBL2-C of the comparative embodiment, the angles θ12c, θ22c, θ32c, θ42c, and θ52c of the transmission portions TPC2 arranged in the first row relative to the reference line RL may be the same, and the tilt angle, which is the angle difference between the angles θ12c, θ22c, θ32c, θ42c, and θ52c, may be 0 degrees.

[0261] Compared to the light source image IM2-E captured through the light-blocking layer LBL2-E according to the present invention, the light source image IM2-C captured through the light-blocking layer LBL2-C of the comparative example exhibits relatively significant light splitting. The display panel according to the present invention forms multiple transmissive portions TP2 with different shapes and tilted at different angles in the light-blocking layer LBL2-E. This mitigates light splitting compared to a light-blocking layer LBL2-C comprising transmissive portions TPC2 having identical shapes. According to the present invention, by rotating the uniformly arranged transmissive portions TPC2 having identical shapes, the phenomenon of light diffracting in specific directions can be mitigated. This reduces light leakage or light splitting in specific directions, and improves display characteristics in the first area A1.

The shape of each transmission portion TP3 may be a shape obtained by rotating a reference shape by a predetermined tilt angle, and the tilt angles may be different from each other.

[0264] Specifically, taking the transmissive portion TP3 arranged along the first direction DR1 as an example, the angles θ13, θ23, θ33, θ43, and θ53 at the first vertex close to the reference line RL may be different from each other. In other words, the transmissive portion TP3 arranged along the first direction DR1 may have a shape rotated at different inclination angles.

[0265] Reference Figure 11b, in the light blocking layer LBL3-C of the comparative embodiment, the shape of each of the transmission parts TPC3 may be all the same heptagonal shape.

According to the present invention, by rotating the uniformly arranged transmissive portions TPC7 having the same shape, the phenomenon of light diffracting in specific directions can be mitigated. This can reduce light leakage or light splitting in specific directions, and improve the display characteristics in the first area A1.

[0287] Figure 16a and Figure 16b 3 is a diagram showing a light-blocking layer in a first region and a light source image captured through the first region. Figure 16a shows a light blocking layer LBL8-E and a light source image IM8-E according to an embodiment of the present invention, Figure 16b 1 and 2. A light blocking layer LBL8-C and a light source image IM8-C according to an eighth comparative embodiment are shown. Hereinafter, repeated descriptions will be omitted.

[0288] Reference Figure 16a In the light-blocking layer LBL8-E according to an embodiment of the present invention, the shape of the transmission portion TP8 may include N different hexagonal shapes. The shape of each transmission portion TP8 may be a shape obtained by rotating a reference shape by a predetermined tilt angle, and the tilt angles may be different from each other.

[0289] Specifically, taking the transmissive portion TP8 arranged along the first direction DR1 as an example, the angles θ18, θ28, θ38, θ48, and θ58 at the first vertex close to the reference line RL may be different from each other. In other words, the transmissive portion TP8 arranged along the first direction DR1 may have a shape rotated at different inclination angles.

[0290] Reference Figure 16b , in the light blocking layer LBL8-C of the comparative embodiment, the shape of each of the transmission parts TPC8 may be all the same hexagonal shape. That is, the transmission part TP8 according to the present invention (refer to Figure 16a ) can be obtained by rotating / tilting each of the transmission portions TPC8 of the comparative embodiment at different tilt angles. In the light-blocking layer LBL8-C of the comparative embodiment, the angles θ18c, θ28c, θ38c, θ48c, and θ58c of the transmission portions TPC8 arranged in the first row relative to the reference line RL may be the same, and the tilt angle, which is the angle difference between the angles θ18c, θ28c, θ38c, θ48c, and θ58c, may be 0 degrees.

[0291] Compared to the light source image IM8-E captured through the light-blocking layer LBL8-E according to the present invention, it can be seen that the light source image IM8-C captured through the light-blocking layer LBL8-C of the comparative example exhibits relatively large light splitting. The display panel according to the present invention forms multiple transmissive portions TP8 with different shapes and tilted at different angles in the light-blocking layer LBL8-E. This can alleviate light splitting compared to the light-blocking layer LBL8-C including transmissive portions TPC8 having the same shape. According to the present invention, by rotating the uniformly arranged transmissive portions TPC8 having the same shape, the phenomenon of light diffraction in specific directions can be alleviated. Consequently, light leakage or light splitting in specific directions can be reduced, and the display characteristics in the first area A1 can be improved.

[0292] While the present invention has been described above with reference to preferred embodiments, any person skilled in the art or having ordinary knowledge in the art will appreciate that various modifications and variations may be made to the present invention without departing from the spirit and technical scope of the present invention as set forth in the claims. Therefore, the technical scope of the present invention should not be limited to the details set forth in the specification but should be determined by the claims.
