[0048] Figure 1 is a system configuration diagram of a display device 100 according to an embodiment of the present invention.

[0049] Reference Figure 1 According to an embodiment of the present invention, the display device 100 may include a display panel 110 and a display driving circuit as components for displaying an image. The display driving circuit is a circuit for driving the display panel 110, and may include a data driving circuit 120, a gate driving circuit 130, and a display controller 140.

[0050] The display panel 110 may include a substrate 111 and a plurality of sub-pixels SP disposed on the substrate 111 .

[0051] The substrate 111 of the display panel 110 may include a display area DA capable of displaying an image and a non-display area NDA located outside the display area DA.

[0052] A plurality of sub-pixels SP for displaying an image may be disposed in the display area DA, and the non-display area NDA may include a pad area PA (see FIG. Figure 3 ), the pad area PA is arranged along the first direction from the display area DA.

[0053] In the display panel 110 according to the embodiment of the present invention, the non-display area NDA may be very small. In the present invention, the non-display area NDA may also be referred to as a "frame".

[0054] For example, the non-display area NDA may include: a first non-display area located outside the display area DA in a first direction; a second non-display area located outside the display area DA in a second direction crossing the first direction; a third non-display area located outside the display area DA in a direction opposite to the first direction; and a fourth non-display area located outside the display area DA in a direction opposite to the second direction. One or two of the first to fourth non-display areas may include a pad area to which the data driving circuit 120 is connected or bonded. Among the first to fourth non-display areas, two or three non-display areas that do not include the pad area may have a very small size.

[0055] In another example, the boundary area between the display area DA and the non-display area NDA may be curved so that the non-display area NDA may be located below the display area. In this case, when the user views the display device 100 from the front, no or almost no non-display area NDA may be visible to the user.

[0056] Various signal lines for driving the plurality of sub-pixels SP may be disposed on the substrate 111 of the display panel 110 .

[0057] The display device 100 according to the embodiment of the present invention may be a liquid crystal display device, etc., or may be a self-luminous display device in which the display panel 110 emits light itself. When the display device 100 according to the embodiment of the present invention is a self-luminous display device, each of the plurality of sub-pixels SP may include a light emitting device.

[0058] For example, the display device 100 according to an embodiment of the present invention may be an organic light-emitting display device, in which the light-emitting device is implemented as an organic light-emitting diode (OLED). In another example, the display device 100 according to an embodiment of the present invention may be an inorganic light-emitting display device, in which the light-emitting device is implemented as an inorganic-based light-emitting diode. In another example, the display device 100 according to an embodiment of the present invention may be a quantum dot display device, in which the light-emitting device is implemented using quantum dots that are self-luminous semiconductor crystals.

[0059] The structure of each of the plurality of subpixels SP may vary according to the type of the display device 100. For example, if the display device 100 is a self-luminous display device having self-luminous subpixels SP, each subpixel SP may include a self-luminous light emitting device, one or more transistors, and one or more capacitors.

[0060] For example, the various signal lines may include: a plurality of data lines DL for providing data signals (also referred to as data voltages or image signals); and a plurality of gate lines GL for transmitting gate signals (also referred to as scan signals).

[0061] For example, a plurality of data lines DL and a plurality of gate lines GL may cross each other. Each of the plurality of data lines DL may be arranged to extend in a first direction. Each of the plurality of gate lines GL may be arranged to extend in a second direction. Here, the first direction may be a column direction, and the second direction may be a row direction. Alternatively, the first direction may be a row direction, and the second direction may be a column direction. Hereinafter, for ease of explanation, a case in which each of the plurality of data lines DL is arranged in a column direction and each of the plurality of gate lines GL is arranged in a row direction will be exemplified.

[0062] The data driving circuit 120 is a circuit for driving the plurality of data lines DL, and may output data signals to the plurality of data lines DL.

[0063] The data driving circuit 120 may receive the image data DATA in a digital form from the display controller 140 , convert the received image data DATA into analog data signals, and output them to the plurality of data lines DL.

[0064] For example, the data driving circuit 120 can be connected to the display panel 110 by using a tape automated bonding (TAB) method, or can be connected to a bonding pad of the display panel 110 using a chip on glass (COG) method or a chip on panel (COP) method, or can be implemented and connected to the display panel 110 using a chip on film (COF) method.

[0065] The data driving circuit 120 may be connected to one side (e.g., the upper side or the lower side) of the display panel 110. The data driving circuit 120 may be connected to both sides (e.g., the upper side and the lower side) of the display panel 110, or may be connected to two or more sides of four sides of the display panel 110 according to a driving method, a panel design method, etc.

[0066] The data driving circuit 120 may be connected to the outside of the display area DA of the display panel 110 , but alternatively, the data driving circuit 120 may be provided in the display area DA of the display panel 110 .

[0067] The gate driving circuit 130 is a circuit for driving the plurality of gate lines GL, and may output gate signals to the plurality of gate lines GL.

[0068] The gate driving circuit 130 may receive a first gate voltage corresponding to a turn-on level voltage and a second gate voltage corresponding to a turn-off level voltage together with various gate driving control signals GCS, and may generate gate signals and provide the generated gate signals to the plurality of gate lines GL.

[0069] In the display device 100 according to the embodiment of the present invention, the gate driving circuit 130 may be built into the display panel 110 as a gate-in-panel (GIP) type. If the gate driving circuit 130 is a gate-in-panel type, the gate driving circuit 130 may be formed on a substrate of the display panel 110 during a manufacturing process of the display panel 110.

[0070] In the display device 100 according to the embodiment of the present invention, the gate driving circuit 130 may be disposed in the display area DA of the display panel 110. For example, the gate driving circuit 130 may be disposed in a first local area within the display area DA (e.g., a left area or a right area within the display area DA). In another example, the gate driving circuit 130 may be disposed in a first local area within the display area DA (e.g., a left area or a right area within the display area DA) and in a second local area within the display area DA (e.g., a right area or a left area within the display area DA).

[0071] In the present invention, the gate driving circuit 130 built into the display panel 110 as a gate-in-panel type may be referred to as a gate-in-panel circuit.

[0072] As described above, the gate driving circuit 130 of the gate-in-panel type may not be connected to or disposed in the non-display area NDA of the display panel 110 , but may be disposed in the display area DA, thereby significantly reducing the bezel of the display panel 110 .

[0073] The display controller 140 may be a device for controlling the data driving circuit 120 and the gate driving circuit 130 , and may control a driving timing of a plurality of data lines DL and a driving timing of a plurality of gate lines GL.

[0074] The display controller 140 may provide a data driving control signal DCS to the data driving circuit 120 to control the data driving circuit 120 , and may provide a gate driving control signal GCS to the gate driving circuit 130 to control the gate driving circuit 130 .

[0075] The display controller 140 may receive image data input from the host system 150 and provide image data DATA to the data driving circuit 120 based on the input image data.

[0076] The display controller 140 may be implemented as a separate component from the data driving circuit 120 , or may be integrated with the data driving circuit 120 and implemented as an integrated circuit.

[0077] The display controller 140 may be a timing controller used in typical display technologies, or may be a control device that can further perform other control functions in addition to performing the functions of the timing controller, or may be a control device different from the timing controller, or may be a control device other than the timing controller, or may be a circuit within the control device. The display controller 140 may be implemented using various circuits or electronic components such as an integrated circuit (IC), a field programmable gate array (FPGA), an application-specific integrated circuit (ASIC), or a processor.

[0078] The display controller 140 may be mounted on a printed circuit board, a flexible printed circuit, or the like, and may be electrically connected to the data driving circuit 120 and the gate driving circuit 130 through the printed circuit board, the flexible printed circuit, or the like.

[0079] The display controller 140 may transmit / receive signals to / from the data driving circuit 120 according to one or more predetermined interfaces. For example, the interface may include a low voltage differential signaling (LVDS) interface, an embedded clock point-to-point interface (EPI), or a serial peripheral interface (SPI).

[0080] In order to provide not only an image display function but also a touch sensing function, the display device 100 according to an embodiment of the present invention may include a touch sensor and a touch sensing circuit, wherein the touch sensing circuit is used to detect whether a touch is generated by a touch object such as a finger or a pen, or to detect a touch position by sensing the touch sensor.

[0081] The touch sensing circuit may include a touch driving circuit for driving and sensing the touch sensor to generate and output touch sensing data, and a touch controller for detecting the presence or absence of a touch or detecting a touch position by using the touch sensing data.

[0082] The touch sensor may include a plurality of touch electrodes. The touch sensor may further include a plurality of touch wires electrically connecting the plurality of touch electrodes to the touch driving circuit.

[0083] The touch sensor may be present in the form of a touch panel on the outside of the display panel 110, or may be present on the inside of the display panel 110. If the touch sensor is present in the form of a touch panel on the outside of the display panel 110, the touch sensor may be referred to as an outside type. If the touch sensor is an outside type, the touch panel and the display panel 110 may be manufactured separately and combined during the assembly process. The outside touch panel may include a touch panel substrate and a plurality of touch electrodes on the touch panel substrate.

[0084] If the touch sensor exists inside the display panel 110 , the touch sensor may be formed on the substrate 111 together with signal lines and electrodes related to display driving during a manufacturing process of the display panel 110 .

[0085] The touch driving circuit may provide a touch driving signal to at least one of the plurality of touch electrodes, and generate touch sensing data by sensing at least one of the plurality of touch electrodes.

[0086] The touch sensing circuit may perform touch sensing by using a self-capacitance sensing method or a mutual capacitance sensing method.

[0087] If the touch sensing circuit performs touch sensing by using a self-capacitance sensing method, the touch sensing circuit may perform touch sensing based on the capacitance between each touch electrode and a touch object (e.g., a finger, a pen, etc.). According to the self-capacitance sensing method, each of the plurality of touch electrodes may be used as a driving touch electrode and a sensing touch electrode. The touch driving circuit may drive all or part of the plurality of touch electrodes, and sense all or part of the plurality of touch electrodes.

[0088] If the touch sensing circuit performs touch sensing by using a mutual capacitance sensing method, the touch sensing circuit may perform touch sensing based on the capacitance between touch electrodes. According to the mutual capacitance sensing method, a plurality of touch electrodes may be divided into driving touch electrodes and sensing touch electrodes. The touch driving circuit may drive the driving touch electrodes and sense the sensing touch electrodes.

[0089] The touch driving circuit and the touch controller included in the touch sensing circuit may be implemented as separate devices or one device. In addition, the touch driving circuit and the data driving circuit may be implemented as separate devices or one device.

[0090] Meanwhile, a plurality of touch lines (or a plurality of touch wirings) for electrically connecting a plurality of touch electrodes constituting the touch sensor and the touch driving circuit may be arranged across the display area DA without bypassing an area where no pads are present (e.g. Figure 3 The non-display area NDA in the pad area PA) Figure 3 The second, third and fourth non-display areas NDA2, NDA3 and NDA4 in FIG. 1 extend to the pad area (eg Figure 3 The pad area PA in the circuit.

[0091] Therefore, the area where there is no pad (eg Figure 3 The non-display area NDA (eg, the pad area PA) Figure 3 The sizes of the second, third and fourth non-display areas NDA2, NDA3 and NDA4) in the display are reduced, thereby significantly reducing the frame size.

[0092] The display device 100 may further include a power circuit for providing various power sources to the display driving circuit and / or the touch sensing circuit.

[0093] The display device 100 according to an embodiment of the present invention may be a mobile terminal such as a smart phone or a tablet, or a display or a television of various sizes, but is not limited thereto, and may be a display of various types and sizes capable of displaying information or images.

[0094] The display device 100 according to the embodiment of the present invention may further include electronic devices such as a camera (eg, an image sensor) and a detection sensor. For example, the detection sensor may be a sensor for detecting an object or a human body by receiving light such as infrared, ultrasonic or ultraviolet rays.

[0095] Figure 2 A display panel 110 according to an embodiment of the present invention is illustrated.

[0096] Reference Figure 2 The display panel 110 may include: a substrate 111 on which a plurality of sub-pixels SP are disposed; and an encapsulation layer 200 on the substrate 111. Here, the encapsulation layer 200 may also be referred to as an encapsulation substrate or an encapsulation part.

[0097] Reference Figure 2 When the display device 100 according to the embodiment of the present invention is a self-luminous display device, each of the plurality of sub-pixels SP may include a light emitting device ED and a sub-pixel circuit SPC for driving the light emitting device ED.

[0098] Reference Figure 2, the sub-pixel circuit SPC may include a plurality of pixel driving transistors and at least one capacitor for driving the light emitting device ED. In the present invention, the sub-pixel circuit SPC may drive the light emitting device ED by providing a driving current to the light emitting device ED at a predetermined timing. The light emitting device ED may be driven by the driving current and emit light.

[0099] The plurality of pixel driving transistors may include: a driving transistor DT for driving the light emitting device ED; and a scanning transistor ST which is turned on or off according to a scanning signal SC.

[0100] The driving transistor DT may provide a driving current to the light emitting device ED.

[0101] The scan transistor ST may be configured to control an electrical state of a corresponding node in the sub-pixel circuit SPC, or to control a state or operation of the drive transistor DT.

[0102] The at least one capacitor may include a storage capacitor Cst to maintain a constant voltage during one frame.

[0103] To drive the subpixel SP, a data signal VDATA as an image signal and a scan signal SC as a gate signal may be applied to the subpixel SP. In addition, a common pixel driving voltage including a first driving voltage VDD and a second driving voltage VSS may be applied to the subpixel SP to drive the subpixel SP.

[0104] The light emitting device ED may include a pixel electrode PE, an intermediate layer EL, and a common electrode CE. The intermediate layer EL may be located between the pixel electrode PE and the common electrode CE.

[0105] For example, the pixel electrode PE may be an anode AND, and the common electrode CE may be a cathode CAT. Alternatively, the pixel electrode PE may be a cathode CAT, and the common electrode CE may be an anode AND. Hereinafter, for ease of explanation, the case where the pixel electrode PE is an anode AND and the common electrode CE is a cathode CAT will be exemplified.

[0106] In the case where the light emitting device ED is an organic light emitting device, the intermediate layer EL may include: a light emitting layer EML; a first common intermediate layer COM1 located between the anode AND and the light emitting layer EML; and a second common intermediate layer COM2 located between the light emitting layer EML and the cathode. The light emitting layer EML may be disposed in each sub-pixel SP. In contrast, the first common intermediate layer COM1 and the second common intermediate layer COM2 may be commonly disposed across a plurality of sub-pixels SP. The light emitting layer EML may be disposed in each light emitting region, and the first common intermediate layer COM1 and the second common intermediate layer COM2 may be commonly disposed across a plurality of light emitting regions and non-light emitting regions. The first common intermediate layer COM1 and the second common intermediate layer COM2 may be collectively referred to as a common intermediate layer EL_COM.

[0107] For example, the first common intermediate layer COM1 may include a hole injection layer HIL and a hole transport layer HTL, and the second common intermediate layer COM2 may include an electron transport layer ETL and an electron injection layer EIL. The hole injection layer may inject holes from the anode AND into the hole transport layer, and the hole transport layer may transport the holes to the light emitting layer EML. The electron injection layer may inject electrons from the cathode CAT into the electron transport layer, and the electron transport layer may transport the electrons to the light emitting layer EML.

[0108] For example, the cathode CAT may be electrically connected to the second driving voltage line VSSL. The second driving voltage VSS, which is a common pixel driving voltage, may be applied to the cathode CAT via the second driving voltage line VSSL. The anode AND may be electrically connected to the first node N1 of the driving transistor DT of each sub-pixel SP. In the present invention, the second driving voltage VSS may also be referred to as the base voltage VSS, and the second driving voltage line VSSL may also be referred to as the base voltage line VSSL.

[0109] For example, the pixel electrode PE may be an electrode provided in each sub-pixel SP, and the common electrode CE may be an electrode commonly provided in a plurality of sub-pixels SP.

[0110] Each light emitting device ED may be formed by an overlapping portion of the pixel electrode PE, the intermediate layer EL, and the common electrode CE. A predetermined light emitting region may be formed through each light emitting device ED. For example, the light emitting region of each light emitting device ED may include an overlapping region of the pixel electrode PE, the intermediate layer EL, and the common electrode CE.

[0111] For example, the light emitting device ED may be an organic light emitting diode (OLED), an inorganic light emitting diode, or a quantum dot light emitting device. For example, in the case where the light emitting device ED is an organic light emitting diode OLED, the intermediate layer EL in the light emitting device ED may include an organic intermediate layer EL containing an organic material.

[0112] The driving transistor DT may be a driving transistor for supplying a driving current to the light emitting device ED. The driving transistor DT may be connected between the first driving voltage line VDDL and the light emitting device ED.

[0113] The driving transistor DT may include a first node N1 electrically connected to the light emitting device ED, a second node N2 to which a data signal VDATA is applied, and a third node N3 to which a driving voltage VDD from the first driving voltage line VDDL is applied.

[0114] In the driving transistor DT, the second node N2 may be a gate node, the first node N1 may be a source node or a drain node, and the third node N3 may be a drain node or a source node. Hereinafter, for ease of explanation, a case where the second node N2 in the driving transistor DT is a gate node, the first node N1 is a source node, and the third node N3 is a drain node will be described.

[0115] Figure 2 The scanning transistor ST included in the shown sub-pixel circuit SPC may be a switching transistor that transmits a data signal VDATA, which is an image signal, to the second node N2 that is the gate node of the driving transistor DT.

[0116] The scanning transistor ST can be turned on / off by a scanning signal SC, which is a kind of gate signal, applied via a scanning line SCL that is a kind of gate line, and can control the electrical connection between the second node N2 of the driving transistor DT and the data line DL. The drain or source of the scanning transistor ST can be electrically connected to the data line DL, and the source or drain of the scanning transistor ST can be electrically connected to the second node N2 of the driving transistor DT. The gate of the scanning transistor ST can be electrically connected to the scanning line SCL.

[0117] The storage capacitor Cst can be electrically connected between the first node N1 and the second node N2 of the driving transistor DT. The storage capacitor Cst can include: a first capacitor electrode electrically connected to the first node N1 of the driving transistor DT or corresponding to the first node N1 of the driving transistor DT; and a second capacitor electrode electrically connected to the second node N2 of the driving transistor DT or corresponding to the second node N2 of the driving transistor DT.

[0118] The storage capacitor Cst can be an external capacitor specifically designed outside the driving transistor DT, rather than a parasitic capacitor (such as Cgs, Cgd) that can exist as an internal capacitor between the first node N1 and the second node N2 of the driving transistor DT.

[0119] Each of the driving transistor DT and the scanning transistor ST can be an n-type transistor or a p-type transistor.

[0120] The display panel 110 can have a top-emission structure or a bottom-emission structure.

[0121] If the display panel 110 has a top-emission structure, at least a part of the sub-pixel circuit SPC can overlap at least a part of the light-emitting device ED in the vertical direction. Optionally, if the display panel 110 has a bottom-emission structure, the sub-pixel circuit SPC can not overlap the light-emitting device ED in the vertical direction.

[0122] As Figure 2As shown, the sub-pixel circuit SPC may have a 2T1C structure including two transistors DT and ST and one capacitor Cst. In some cases, the sub-pixel circuit SPC may further include one or more transistors or one or more capacitors.

[0167] Refer to Figure 4 According to an embodiment of the present invention, the display panel 110 may include a first inorganic layer PAS1, a first organic layer PCL1, and a second inorganic layer PAS2.

[0168] Refer to Figure 4 The first inorganic layer PAS1 may be located on the common electrode CE and may be disposed to extend from the display area DA to the non-display area NDA.

[0178] The first to third light-emitting layers EML1, EML2, and EML3 may be located on the first common intermediate layer COM1 and may overlap the first to third pixel electrodes PE1, PE2, and PE3. The first to third light-emitting layers EML1, EML2, and EML3 may correspond to the first to third light-emitting regions EA1, EA2, and EA3.

[0179] The second common intermediate layer COM2 may be commonly disposed on the first to third light-emitting layers EML1, EML2, and EML3 and may also be disposed on the bank BK.

[0180] As described above, the common intermediate layer EL_COM including the first common intermediate layer COM1 and the second common intermediate layer COM2 may be disposed on the bank BK.

[0181] The common intermediate layer EL_COM may be disposed on the entire display area DA. Each of the first common intermediate layer COM1 and the second common intermediate layer COM2 may include an organic material.

[0182] The common electrode CE may be located on the second common intermediate layer COM2.

[0183] Refer to Figure 4, the common intermediate layer EL_COM and the common electrode CE can extend to the upper part of the stopper STP. Therefore, the common intermediate layer EL_COM and the common electrode CE can overlap at least a part of the stopper STP.

[0184] For example, the common intermediate layer EL_COM and the common electrode CE can extend to the top and the outside of the stopper STP. When the common intermediate layer EL_COM and the common electrode CE further extend, the common intermediate layer EL_COM and the common electrode CE can pass through the top and the outside of the stopper STP and extend to the outside SIDE_INS of the insulating laminate INS.

[0185] Referring to Figure 4 , the display panel 110 can further include a cover layer CPL, which is located between the common electrode CE and the first inorganic layer PAS1 and extends from the display area DA to the non-display area NDA. The cover layer CPL can extend along the upper part and the outside of the stopper STP to the outside SIDE_INS of the insulating laminate INS.

[0186] Referring to Figure 4 , the common intermediate layer EL_COM, the common electrode CE and the cover layer CPL can be disposed on the outside SIDE_INS of the insulating laminate INS.

[0187] As described above, the stopper STP can be disposed outside the first light-emitting device ED1, which is the outermost light-emitting device ED among the plurality of light-emitting devices ED1, ED2, and ED3 corresponding to the plurality of sub-pixels SP, and can have a greater thickness than the first pixel electrode PE1 of the first light-emitting device ED1.

[0188] Referring to Figure 4 , the lower surface of the stopper STP can have a greater area than the upper surface of the stopper STP.

The bank material and / or the spacer material can be the same material or can be different materials. The bank material and / or the spacer material can include an organic material.

[0189] Each of the first inorganic layer PAS1 and the second inorganic layer PAS2 can be formed of silicon nitride, aluminum nitride, zinc nitride, titanium nitride, hafnium nitride, tantalum nitride, silicon oxide, aluminum oxide, or titanium oxide.

[0190] For example, the first organic layer PCL1 may be formed of an acrylic resin, an epoxy resin, a phenolic resin, or a polyimide resin. The first organic layer PCL1 may be formed in a liquid form by coating via an inkjet process and then via a curing process.

[0191] According to Figure 4 the shown blocker structure, a very narrow bezel structure of the display panel 110 is possible.

[0192] In the display panel 110 having Figure 4 the shown blocker STP, the intermediate layer EL, the common electrode CE, and the cover layer CPL may pass through the upper side and the outer side of the blocker STP and may be arranged to extend to the outside of the first organic layer PCL1 of the encapsulation layer 200. Accordingly, the intermediate layer EL, the common electrode CE, and the cover layer CPL may be more likely to be exposed to a vulnerable environment. Here, the vulnerable environment may represent an environment exposed to moisture or oxygen.

[0193] Therefore, when the display panel 110 includes Figure 4 the shown blocker STP, it may be difficult to ensure reliability. When the display panel 110 includes Figure 4 the shown blocker STP, it may not be easy to perform a process of disconnecting the intermediate layer EL, the common electrode CE, and the cover layer CPL at the outermost point or the innermost point of the first organic layer PCL1 of the encapsulation layer 200.

[0194] Therefore, the display device 100 according to an embodiment of the present invention may further include a blocker structure that is conducive to ensuring high reliability while enabling a very narrow bezel. Hereinafter, a blocker structure that is conducive to ensuring high reliability while enabling a very narrow bezel will be described with reference to the accompanying drawings.

[0195] Figure 5 is a cross-sectional view of a display panel 110 according to an embodiment of the present invention.

[0196] Referring to Figure 5 , the display device 100 according to an embodiment of the present invention may include: a substrate 111 having a display area DA capable of displaying an image and a non-display area NDA different from the display area DA; a plurality of light-emitting devices ED1 and ED2 disposed on the substrate 111; and a first organic layer PCL1 disposed on the plurality of light-emitting devices ED1 and ED2.

[0197] Referring to Figure 5 , the display device 100 according to an embodiment of the present invention may include a blocker STP disposed outside the outermost light-emitting device ED1 among the plurality of light-emitting devices ED1 and ED2 and located outside the first organic layer PCL1.

[0198] Referring toFigure 5 In the display device 100 according to an embodiment of the present invention, the blocker STP may be disposed higher than the pixel electrodes PE1 and PE2 of each of the plurality of light-emitting devices ED1 and ED2. That is, the blocker STP may be further away from the substrate 111 than the pixel electrodes PE1 and PE2 of each of the plurality of light-emitting devices ED1 and ED2.

[0199] Refer to Figure 5 In the display device 100 according to an embodiment of the present invention, the inner side S1 of the blocker STP may have an inverted conical shape.

[0200] Refer to Figure 5 In the display device 100 according to an embodiment of the present invention, the outer side S4 of the blocker STP may have a regular conical shape.

[0201] Refer to Figure 5 The display device 100 according to an embodiment of the present invention may further include an intermediate layer EL, which constitutes the plurality of light-emitting devices ED1 and ED2 and is present on the inner side S1 of the blocker STP, but not on the outer side S4 of the blocker STP.

[0202] Refer to Figure 5 The display device 100 according to an embodiment of the present invention may further include a separation material layer ELs, which is disposed on the upper portion of the blocker STP, is separated from the intermediate layer EL present on the inner side S1 of the blocker STP, and contains the same material as the intermediate layer EL.

[0203] Hereinafter, the display device 100 according to an embodiment of the present invention will be described in more detail.

[0204] Refer to Figure 5 The display device 100 according to an embodiment of the present invention may include: a substrate 111 including a display area DA and a non-display area NDA; a plurality of light-emitting devices ED1 and ED2 disposed on the substrate 111; a bank BK for defining light-emitting areas EA1 and EA2 of each of the plurality of light-emitting devices ED1 and ED2; and a packaging layer 200 located on the plurality of light-emitting devices ED1 and ED2 and the bank BK.

[0205] The packaging layer 200 may include: a first inorganic layer PAS1 located on the plurality of light-emitting devices ED1 and ED2 and the bank BK; a first organic layer PCL1 located on the first inorganic layer PAS1; and a second inorganic layer PAS2 located on the first organic layer PCL1.

[0206] Refer to Figure 5, the display device 100 according to an embodiment of the present invention may further include a first insulating layer 530 disposed on the substrate 111 and a second insulating layer 540 located on the first insulating layer 530.

[0207] At least one of the first insulating layer 530 and the second insulating layer 540 may include a planarization layer.

[0208] Referring to Figure 5 , a plurality of light emitting devices ED1 and ED2 may be disposed on the second insulating layer 540.

[0209] Referring to Figure 5 , the display device 100 according to an embodiment of the present invention may include a stopper STP, which is disposed outside the display area DA and located on the outermost upper portion of the bank BK.

[0210] Regarding the horizontal position of the stopper STP, the stopper STP may be disposed outside the display area DA, and at least a part of the stopper STP may be further disposed outside the first organic layer PCL1.

[0211] Regarding the vertical position of the stopper STP, the stopper STP may be located at the outermost upper portion of the bank BK.

[0212] Regarding the shape of the stopper STP, the inner side S1 of the stopper STP may have an inverted conical shape. In addition, the outer side S4 of the stopper STP may have a regular taper shape.

[0213] The inner side S1 of the stopper STP has an inverted conical shape, so that the intermediate layer EL, the common electrode CE, and the cover layer CPL may not extend outside the first organic layer PCL1 and may be disconnected near or at the outermost point of the first organic layer PCL1. As a result, high reliability of the display panel 110 can be ensured.

[0214] Since the outer side S4 of the stopper STP has a regular taper shape, the second inorganic layer PAS2 may not be disconnected at the outer side S4 of the stopper STP, and may cover the outside of the bank BK and extend to or near the upper surface of the substrate 110 while completely covering the stopper STP. Therefore, the encapsulation performance of the encapsulation layer can be improved.

[0215] Regarding the material of the stopper STP, for example, the stopper STP may include an inorganic material. As another example, the stopper STP may include an organic material. As still another example, the stopper STP may include inorganic and organic materials.

[0216] In the case where the stopper STP includes an inorganic material, it may be easy to form the inner side S1 of the stopper STP into an inverted conical shape.

[0217] In the case where the stopper STP includes both an inorganic material and an organic material, it is easy to form the inner side S1 of the stopper STP into an inverted cone shape and the outer side S4 of the stopper STP into a regular cone shape.

[0218] Refer to Figure 5 , in the display device 100 according to an embodiment of the present invention, the stopper STP may include: a first stopper part STP1 including a first side S1 and a second side S2; and a second stopper part STP2 including a third side S3 and a fourth side S4.

[0219] Refer to Figure 5 , the first stopper part STP1 may be disposed closer to the display area DA than the second stopper part STP2.

[0220] The first side S1 of the first stopper part STP1 may be disposed closer to the display area DA than the second side S2 of the first stopper part STP1.

[0221] The third side S3 of the second stopper part STP2 may be disposed closer to the display area DA than the fourth side S4 of the second stopper part STP2.

[0222] The second side S2 of the first stopper part STP1 and the third side S3 of the second stopper part STP2 may be in contact with each other.

[0223] The first stopper part STP1 and the second stopper part STP2 included in the stopper STP may be formed integrally. Alternatively, the first stopper part STP1 and the second stopper part STP2 may be separately formed patterns.

[0224] The first stopper part STP1 and the second stopper part STP2 may be simultaneously formed patterns, or may be separately formed patterns via different processes.

[0225] Refer to Figure 5 , in the display device 100 according to an embodiment of the present invention, the first side S1 of the first stopper part STP1 may be the inner side of the stopper STP and may have an inverted cone shape.

[0226] Refer to Figure 5 , in the display device 100 according to an embodiment of the present invention, the fourth side S4 of the second stopper part STP2 may have a regular cone shape.

[0227] Since the first side S1 of the first stopper part STP1 has an inverted cone shape, the intermediate layer EL, the common electrode CE, and the cover layer CPL may not extend to the outer edge of the first organic layer PCL1 and may be disconnected or broken near or at the outermost point of the first organic layer PCL1. As a result, high reliability of the display panel 110 can be ensured.

[0228] Since the fourth side S4 of the second stopper part STP2 has a positive taper, the second inorganic layer PAS2 may not be disconnected at the fourth side S4 of the second stopper part STP2, may cover the outer side of the bank part BK, and may extend to or near the upper surface of the substrate 111 while completely covering the stopper STP. Accordingly, the encapsulation performance of the encapsulation layer can be improved.

[0229] Refer to Figure 5 , in the display device 100 according to an embodiment of the present invention, the first stopper part STP1 may include an inorganic material. When the first stopper part STP1 includes an inorganic material, it may be easy to form the first side S1 of the first stopper part STP1 into an inverted taper.

[0230] Refer to Figure 5 , in the display device 100 according to an embodiment of the present invention, the second stopper part STP2 may include an inorganic material. If the second stopper part STP2 includes an inorganic material, it may be easy to form the first stopper part STP1 and the second stopper part STP2 simultaneously and integrally.

[0231] Refer to Figure 5 , in the display device 100 according to an embodiment of the present invention, the second stopper part STP2 may include an organic material.

[0232] If the second stopper part STP2 includes an organic material, it may be easy to form the fourth side S4 of the second stopper part STP2 into a positive taper. As a result, the second inorganic layer PAS2 may extend without being disconnected at the fourth side S4 of the second stopper part STP2. Accordingly, the encapsulation performance of the encapsulation layer can be improved.

[0233] Refer to Figure 5 , each of the plurality of light emitting devices ED1 and ED2 may include a pixel electrode PE1 and PE2, an intermediate layer EL, and a common electrode CE.

[0234] Refer to Figure 5 , each of the plurality of light emitting devices ED1 and ED2 may include a light emitting layer EML and a common intermediate layer EL_COM (see Figure 2 ).

[0235] Refer to Figure 5 , the common intermediate layer EL_COM included in each intermediate layer EL of the plurality of light emitting devices ED1 and ED2 may be connected to each other, and the common intermediate layer EL_COM may be located inside the first side S1 of the first stopper part STP1.

[0236] Refer to Figure 5, the display device 100 according to an embodiment of the present invention may further include a separation material layer ELs, which is disposed on the blocker STP and contains the same material as the common intermediate layer EL_COM, but is separated from the common intermediate layer EL_COM.

[0237] For example, the separation material layer ELs may be disposed on the first blocker part STP1, but not on the second blocker part STP2.
