[0035] In the following description of examples or embodiments of the invention, reference will be made to the accompanying drawings, in which specific examples or embodiments that may be implemented are illustrated by way of illustration, and wherein the same reference numerals and symbols may be used to denote the same or similar parts, even if they are shown in different drawings. Furthermore, in the following description of examples or embodiments of the invention, a detailed description of known functions and parts included herein will be omitted where it is determined that such detailed description may obscure the subject matter of some embodiments of the invention. Terms such as “comprising,” “having,” “including,” “constituting,” “made of,” “composed of,” and “formed by” as used herein are generally intended to allow for the addition of additional parts, unless these terms are used in conjunction with the term “only.” As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise.

[0036] Terms such as “first,” “second,” “A,” “B,” “(A),” or “(B)” may be used herein to describe elements of the invention. Each of these terms is not used to define the elements, order, sequence, or quantity, but only to distinguish the corresponding element from other elements.

[0037] When it is mentioned that the first element is "connected to or coupled to," "in contact with," or "overlaps" with the second element, it should be understood that the first element can not only be "directly connected to or coupled to," "directly contact" with, or "directly overlap" with the second element, but also can "insert" a third element between the first and second elements, or the first and second elements can be "connected to or coupled to," "in contact with," or "overlap" with each other via a fourth element.

Additionally, the term "may" fully encompasses all the meanings of the term "can."

[0040] In the following, various embodiments of this disclosure will be described in detail with reference to the accompanying drawings.

[0041] Figure 1 This is a schematic system configuration diagram of an organic light-emitting display device according to an embodiment of the present disclosure.

[0042] An organic light-emitting display device 100 according to embodiments of this disclosure may include an organic light-emitting display device 100, an illumination device, a light-emitting device, etc. Hereinafter, for ease of description, the organic light-emitting display device 100 will be primarily described. However, it is equally applicable to the organic light-emitting display device 100 and various other organic light-emitting display devices 100 such as illumination devices and light-emitting devices, provided that these devices include transistors.

[0043] An organic light-emitting display device 100 according to an embodiment of the present disclosure may include a display panel PNL for displaying images or outputting light and a driving circuit for driving the display panel PNL.

[0044] Furthermore, the organic light-emitting display device 100 according to embodiments of this disclosure may be a bottom-emitting type organic light-emitting display device in which light is emitted toward a substrate on which light-emitting elements are disposed, but this disclosure is not limited thereto. In some cases, the organic light-emitting display device 100 of this disclosure may be a top-emitting type in which light is emitted toward a surface opposite to the substrate on which light-emitting elements are disposed, or may be a dual-emitting type in which light emitted from the light-emitting elements is emitted toward both the substrate and the surface opposite to the substrate.

[0045] In a display panel PNL, multiple data lines DL and multiple gate lines GL can be set. Multiple sub-pixels SP defined by the multiple data lines DL and multiple gate lines GL can be arranged in a matrix type in the display panel PNL.

[0046] In a display panel PNL, multiple data lines DL and multiple gate lines GL can be arranged to intersect each other. For example, multiple gate lines GL can be arranged in rows or columns, and multiple data lines DL can be arranged in columns or rows. In the following description, for ease of description, it is assumed that multiple gate lines GL are arranged in rows and multiple data lines DL are arranged in columns.

[0047] In addition to multiple data lines (DL) and multiple gate lines (GL), other types of signal lines can be set in the display panel PNL according to the sub-pixel structure, etc. Drive power lines, reference power lines, or common power lines can also be set in the display panel PNL.

[0048] The type of signal line provided in the display panel PNL can vary depending on the sub-pixel structure, etc. In this specification, a signal line can be a concept that includes electrodes to which signals are applied.

[0049] The display panel PNL may include an active area AA in which an image (video) is displayed, and a non-active area NA surrounding the active area NA and in which no image is displayed. Here, the non-active area NA is also referred to as the border area.

[0050] Multiple subpixels SP used to display the image are set in the active region AA.

[0051] The pad area for the data driver DDR and its electrical connection can be located in the non-active area NA. Multiple data link lines used to connect the pad area and multiple data lines DL can also be located in the non-active area NA. Here, the multiple data link lines can be portions of the multiple data lines DL extended into the non-active area NA, or they can be separate patterns electrically connected to the multiple data lines DL.

[0052] Furthermore, the gate drive-related lines, which transmit the voltage (signal) required for gate driving to the gate driver GDR via the pads electrically connected to the gate driver GDR, can be located in the non-active region NA. For example, the gate drive-related lines may include clock lines for transmitting clock signals, gate power lines for transmitting gate voltages VGH and VGL, and gate drive control signal lines for transmitting various control signals required to generate scan signals. Unlike the gate line GL located in the active region AA, the gate drive-related lines are located in the non-active region NA.

[0053] The driving circuit may include a data driver DDR that drives multiple data lines DL, a gate driver GDR that drives multiple gate lines GL, and a controller CTR that controls the data driver DDR and the gate driver GDR.

[0054] The data driver DDR can drive multiple data lines DL by outputting data voltage to multiple data lines DL.

[0055] The gate driver GDR can drive multiple gate lines GL by outputting scan signals to multiple gate lines GL.

[0056] The controller CTR can control the drive operation of the data driver DDR and the gate driver GDR by providing various control signals DCS and GCS required for their operation. Additionally, the controller CTR can supply image data DATA to the data driver DDR.

[0057] The controller CTR begins scanning according to the timing implemented in each frame. The controller CTR converts image data input from external devices into a data signal format suitable for use by the data driver DDR, outputs the converted image data, and controls the data drive at appropriate times according to the scan.

[0058] To control the data driver DDR and the gate driver GDR, the controller CTR can generate various control signals by receiving timing signals such as the vertical synchronization signal Vsync, the horizontal synchronization signal Hsync, the input data enable (DE) signal, and the clock signal CLK from external devices (e.g., the host system). The controller CTR then outputs these generated control signals to the data driver DDR and the gate driver GDR.

[0059] For example, in order to control the gate driver GDR, the controller CTR outputs various gate control signals (GCS) including the gate start pulse (GSP), gate shift clock (GSC), and gate output enable (GOE) signal.

[0060] In addition, in order to control the data driver DDR, the controller CTR outputs various data control signals (DCS) including the source start pulse (SSP), the source sampling clock (SSC), and the source output enable (SOE) signal.

[0061] The controller CTR can be a timing controller used in typical display technologies. Alternatively, the controller CTR can be a control device that includes a timing controller to further perform other control functions.

[0062] The controller CTR can be implemented as a separate component from the data driver DDR. Alternatively, the controller CTR can be integrated with the data driver DDR to be implemented as an integrated circuit.

[0063] The data driver DDR receives image data DATA from the controller CTR and supplies data voltage to multiple data lines DL to drive them. Here, the data driver DDR is also referred to as the source driver.

[0064] The data driver DDR can send various signals to and receive various signals from the controller CTR through various interfaces.

[0065] A gate driver (GDR) sequentially drives multiple gate lines GL by sequentially providing scan signals to them. Here, the gate driver (GDR) is also called a scan driver.

[0066] Under the control of the controller CTR, the gate driver GDR sequentially provides scan signals with on or off voltages to multiple gate lines GL.

[0067] When a specific gate line is turned on by the gate driver GDR, the data driver DDR converts the image data DATA received from the controller CTR into an analog data voltage and provides the analog data voltage to multiple data lines DL.

[0068] The data driver DDR can be located on one side (e.g., the top or bottom) of the display panel PNL. However, this disclosure is not limited thereto. For example, depending on the driving method or display panel design method, the data driver DDR can be located on each of the two sides (e.g., the top and bottom) of the display panel PNL.

[0069] The gate driver GDR can be located on one side (e.g., the left or right side) of the display panel PNL. However, this disclosure is not limited thereto. For example, depending on the driving method or display panel design method, the gate driver GDR can be located on each side (e.g., the left and right sides) of the display panel PNL.

[0070] Data drivers (DDR) can be implemented as including one or more source driver integrated circuits (SDICs).

[0071] Each SDIC may include shift registers, latch circuitry, digital-to-analog converters (DACs), output buffers, etc. In some cases, the data driver DDR may also include one or more analog-to-digital converters (ADCs).

[0072] Each SDIC can be connected to the bonding pads of the display panel PNL using either Tape-on-Board (TAB) or Chip-on-Glass (COG) type. Alternatively, each SDIC can be directly mounted on the display panel PNL. In some cases, the SDIC can be integrated and mounted on the display panel PNL. Furthermore, each SDIC can be implemented as a Chip-on-Film (COF) type. In this case, each SDIC can be mounted on the circuit film. Each SDIC mounted on the circuit film can be electrically connected to the data line DL of the display panel PNL via the circuit film.

[0073] The gate driver GDR may include multiple gate drive circuits GDC. Here, each of the multiple gate drive circuits GDC may correspond to one of multiple gate lines GL.

[0074] Each gate drive circuit (GDC) may include shift registers, level shifters, etc.

[0075] Each gate drive circuit (GDC) can be connected to the bonding pads of the display panel PNL in either a TAB or COG configuration. Alternatively, each GDC can be implemented as a COF configuration. In this case, each GDC can be mounted on a circuit film. Each GDC mounted on the circuit film can be electrically connected to the gate line GL of the display panel PNL via the circuit film. Furthermore, each GDC can be implemented as an in-board gate (GIP) type and embedded within the display panel PNL. Therefore, each GDC can be directly formed on the display panel PNL.

A circuit region may include at least two transistors and at least one storage capacitor. In the first light-emitting region EA1, the first sub-light-emitting region EA11 and the second sub-light-emitting region EA12 of the first light-emitting region EA1 can be driven by a circuit region.

[0085] The first sub-light-emitting region EA21 and the second sub-light-emitting region EA22 of the second light-emitting region EA2 can share a circuit region. In the second light-emitting region EA2, the first sub-light-emitting region EA21 and the second sub-light-emitting region EA22 can be driven by a single circuit region.

[0087] In the third light-emitting region EA3, the first sub-light-emitting region EA31 and the second sub-light-emitting region EA32 of the third light-emitting region EA3 can be driven by a circuit region.

[0088] The fourth luminescent region EA4 may include a first sub-luminescent region EA41 and a second sub-luminescent region EA42. The G-filter 213 may be disposed in each of the first sub-luminescent region EA41 and the second sub-luminescent region EA42 of the fourth luminescent region EA4, but the embodiments of this disclosure are not limited thereto.

[0089] In the fourth light-emitting region EA4, the first sub-light-emitting region EA41 and the second sub-light-emitting region EA42 of the fourth light-emitting region EA4 can be driven by a circuit region.

[0090] Multiple luminescent regions EA1, EA2, EA3 and EA4 can be set in multiple rows and columns within the active region AA.

[0091] Specifically, at least one first light-emitting region EA1, at least one second light-emitting region EA2, at least one third light-emitting region EA3, and at least one fourth light-emitting region EA4 can be set in each row.

[0092] In a row, the first sub-light-emitting region EA11 and the second sub-light-emitting region EA12 of the first light-emitting region EA1 can be set separately from each other. In addition, the circuit area of ​​the first light-emitting region EA1 can be set between the first sub-light-emitting region EA11 and the second sub-light-emitting region EA12 of the first light-emitting region EA1.

[0093] Furthermore, within a single row, the first sub-light-emitting region EA21 and the second sub-light-emitting region EA22 of the second light-emitting region EA2, which are adjacent to the first light-emitting region EA1, can be configured to be separate from each other. The circuit region of the second light-emitting region EA2 can be located between the first sub-light-emitting region EA21 and the second sub-light-emitting region EA22 of the second light-emitting region EA2.

[0094] In a row, the first sub-light-emitting region EA31 and the second sub-light-emitting region EA32 of the third light-emitting region EA3, which are adjacent to the second light-emitting region EA2, can be set separately from each other. The circuit area of ​​the third light-emitting region EA3 can be set between the first sub-light-emitting region EA31 and the second sub-light-emitting region EA32 of the third light-emitting region EA3.

[0095] Furthermore, within a single row, the first sub-light-emitting region EA41 and the second sub-light-emitting region EA42 of the fourth light-emitting region EA4, which are adjacent to the third light-emitting region EA3, can be configured to be separate from each other. The circuit region of the fourth light-emitting region EA4 can be located between the first sub-light-emitting region EA41 and the second sub-light-emitting region EA42 of the fourth light-emitting region EA4.

[0096] The first sub-light-emitting regions EA11, EA21, EA31 and EA41 of the light-emitting regions EA1, EA2, EA3 and EA4 in the same row of the active region AA can be arranged side by side with each other. The circuit regions of the light-emitting regions EA1, EA2, EA3 and EA4 can also be arranged side by side with each other. Furthermore, the second sub-light-emitting regions EA12, EA22, EA32 and EA42 of the light-emitting regions EA1, EA2, EA3 and EA4 can also be arranged side by side with each other.

[0097] Sub-lighting areas of each of the light-emitting areas EA1, EA2, EA3 and EA4 set in the same row can be connected by connecting pattern 230.

[0098] Specifically, each of the sub-light-emitting regions EA11, EA12, EA21, EA22, EA31, EA32, EA41, and EA42 included in the light-emitting regions EA1, EA2, EA3, and EA4 may include an anode 220 (hereinafter referred to as the first electrode) of an organic light-emitting element. The connection pattern 230 may be connected to at least two anodes 220.

[0099] For example, one end of the first electrode 220 disposed in the first sub-light-emitting region EA11 of the first light-emitting region EA1 can be connected to one end of the connecting pattern 230, and one end of the first electrode 220 disposed in the second sub-light-emitting region EA12 of the first light-emitting region EA1 can be connected to the other end of the connecting pattern 230.

[0100] The connection pattern 230 connected to the first electrode 220 disposed in the first sub-light-emitting region EA11 and the second sub-light-emitting region EA12 of the first light-emitting region EA1 can be electrically connected to the circuit region of the first light-emitting region EA1 located between the first sub-light-emitting region EA11 and the second sub-light-emitting region EA12.

[0101] For example, the first connection pattern 231 can be connected to the first sub-light-emitting region EA11, and the second connection pattern 232 can be connected to the second sub-light-emitting region EA12. In this case, the connection pattern 230 can be electrically connected to a transistor (e.g., a driving transistor) located in the circuit region through a contact hole CNT formed in an insulating layer disposed below the connection pattern 230.

[0102] Furthermore, each of the ends of the first electrode 220 disposed in the first sub-light-emitting regions EA21, EA31 and EA41 of the second to fourth light-emitting regions EA2, EA3 and EA4 can also be connected to one end of a connection pattern 230, and each of the ends of the first electrode 220 disposed in the second sub-light-emitting regions EA22, EA32 and EA42 of the second to fourth light-emitting regions EA2, EA3 and EA4 can also be connected to the other end of a connection pattern 230.

[0103] At least one repair pattern 240 may be disposed between a first sub-light-emitting region in at least one of the multiple light-emitting regions included in multiple rows of the active region AA and a second sub-light-emitting region disposed in another light-emitting region in a row adjacent to the one light-emitting region.

[0104] For example, at least one repair pattern 240 may be disposed between a second sub-light-emitting region EA12 disposed in the first light-emitting region EA1 in the (N-1)th row and a first sub-light-emitting region EA11 disposed in the first light-emitting region EA1 in the Nth row.

[0105] Furthermore, at least one repair pattern 240 may be disposed between the second sub-light-emitting region EA22 disposed in the second light-emitting region EA2 in the (N-1)th row and the first sub-light-emitting region EA21 disposed in the second light-emitting region EA2 in the Nth row.

[0106] Furthermore, at least one repair pattern 240 may be disposed between the second sub-light-emitting region EA32 of the third light-emitting region EA3 disposed in the (N-1)th row and the first sub-light-emitting region EA31 of the third light-emitting region EA3 disposed in the Nth row, and at least one repair pattern 240 may be disposed between the second sub-light-emitting region EA42 of the fourth light-emitting region EA4 disposed in the (N-1)th row and the first sub-light-emitting region EA41 of the fourth light-emitting region EA4 disposed in the Nth row.

[0107] When foreign objects are generated on the connecting pattern 230 and bright or dark spots appear in a light-emitting area, the connecting pattern 230 can be electrically disconnected from the circuit area by laser cutting. The first electrode 220 of the sub-light-emitting area, which cannot receive voltage from the circuit area due to the electrical disconnection of the connecting pattern 230 from the circuit area, is then connected to the repair pattern 240 by laser welding and electrically connected to the circuit area in another adjacent row, thereby improving image quality.

[0108] Furthermore, in the active area AA of the display panel according to the embodiments of this disclosure, multiple light-emitting areas that emit light of the same color can be arranged in the same column.

[0109] For example, such as Figure 2 As shown, the third emitting region EA3 that emits B light can be set in column M.

[0110] The second emitting region EA2, which emits W light, can be located in the (M-1)th column adjacent to the Mth column, and the fourth emitting region EA4, which emits G light, can be located in the (M+1)th column. Furthermore, the first emitting region EA1, which emits R light, can be located in the (M-2)th column adjacent to the (M-1)th column.

[0111] A color filter may be shared by a first sub-emitting region included in at least one of a plurality of emitting regions disposed in a plurality of rows in an active region AA, and a second sub-emitting region disposed in another emitting region in a row adjacent to the first emitting region.

[0112] For example, the second sub-emitting region EA12 of the first emitting region EA1 in the (N-1)th row and the first sub-emitting region EA11 of the first emitting region EA1 in the Nth row can overlap with the same R color filter 211.

[0113] The second sub-emitting region EA32 of the third emitting region EA3 in row (N-1) and the first sub-emitting region EA31 of the third emitting region EA3 in row N can overlap with the same B color filter 212.

[0114] Furthermore, the second sub-emitting region EA42 of the fourth emitting region EA4 in the (N-1)th row and the first sub-emitting region EA41 of the fourth emitting region EA4 in the Nth row can overlap with the same G color filter 213.

[0115] Alternatively, the color filter may not be located in the second sub-light-emitting region EA22 of the second light-emitting region EA2 located in the (N-1)th row and the first sub-light-emitting region EA21 of the second light-emitting region EA2 located in the Nth row. However, embodiments of this disclosure are not limited to this, and a color filter may be provided.

[0116] As described above, light-emitting areas that emit the same color of light can be arranged in the same column, and at least one repair pattern 240 can be arranged between adjacent light-emitting areas that emit the same color of light.

[0117] The following will refer to Figure 3 and Figure 4 Describe this structure in detail.

[0118] Figure 3 It is along Figure 2 The cross-sectional view of line AB, and Figure 4 It is along Figure 2 A cross-sectional view of the CD line.

[0119] Specifically, Figure 3 This is a cross-sectional view showing the first sub-light-emitting region EA31 of the third light-emitting region EA3 and the first sub-light-emitting region EA41 of the fourth light-emitting region EA4 adjacent to the first sub-light-emitting region EA31 of the third light-emitting region EA3 in the row direction.

[0120] Figure 4 This is a cross-sectional view showing multiple third light-emitting regions EA3 and circuit regions included in the non-light-emitting region NEA in the column direction.

[0121] In the following description, content that is repeated in the above embodiments (configuration, effects, etc.) may be omitted. Furthermore, in the following description, the same reference numerals may be used for components that are repeated in the above embodiments.

[0122] First, refer to Figure 3 The display panel according to the embodiments of the present disclosure may include an insulating layer 301 disposed on a substrate 300.

[0123] Although insulation layer 301 is Figure 3 The insulating layer 301 is shown as a single-layer structure, but the embodiments of the present disclosure are not limited thereto, and the insulating layer 301 may have a multilayer structure with two or more layers.

[0124] The insulating layer 301 may include an inorganic insulating material. For example, the insulating layer 301 may include at least one selected from silicon nitride (SiNx), silicon oxide (SiOx), and silicon oxynitride (SiON).

[0125] The second color filter 212 and the third color filter 213 can be disposed on the insulating layer 301.

[0126] The protective layer 302 can be disposed on the second color filter 212 and the third color filter 213.

[0127] The first electrode 220 of the organic light-emitting element OLED can be disposed on the protective layer 302.

[0128] The first electrode 220 may include a transparent conductive material. For example, the first electrode 220 may include at least one selected from indium tin oxide (ITO), indium zinc oxide (IZO), and indium gallium zinc oxide (IGZO), but this disclosure is not limited thereto.

[0129] The embankment 250 can be disposed on the protective layer 302 and the first electrode 220.

[0130] The embankment 250 may overlap with a portion of the upper surface of the protective layer 302 and a portion of the upper surface of the first electrode 220.

[0131] In the active region AA, the area where the first electrode 220 does not overlap with the embankment 250 is included in the light-emitting region, while the area where the embankment 250 is located is the non-light-emitting region NEA.

[0132] The organic light-emitting layer 360 can be disposed on the first electrode 220 and the embankment 250.

[0133] The second electrode 370 can be disposed on the organic light-emitting layer 360.

[0134] The second electrode 370 may include a reflective conductive material. However, embodiments of this disclosure are not limited thereto.

[0135] An organic light-emitting element (OLED), comprising a first electrode 220, an organic light-emitting layer 360, and a second electrode 370, can emit W light. When the W light emitted from the OLED passes through color filters 212 and 213 disposed in sub-light-emitting regions EA31 and EA41, light of a specific color can be emitted to the outside of the substrate 300.

[0136] For example, refer to Figure 3B light can be emitted from the first sub-emitting region EA31 of the third emitting region EA3, which is provided with a second color filter 212 having the color of B, to the outside of the substrate 300, and G light can be emitted from the first sub-emitting region EA41 of the fourth emitting region EA4, which is provided with a third color filter 213 having the color of G, to the outside of the substrate 300.

[0137] At the same time, although Figure 3 Only the structure of the second color filter 212 and the third color filter 213, which are respectively configured to correspond to the first sub-light-emitting region EA31 of the third light-emitting region EA3 and the first sub-light-emitting region EA41 of the fourth light-emitting region EA4, is shown. However, the cross-sectional structures of the second sub-light-emitting region EA32 of the third light-emitting region EA3 and the second sub-light-emitting region EA42 of the fourth light-emitting region EA4 can also be the same. Figure 3 The same.

[0138] Furthermore, the first sub-light-emitting region EA11 and the second sub-light-emitting region EA12 of the first light-emitting region EA1 can also have the following characteristics: Figure 3 The structure shown consists of a substrate 300, an insulating layer 301, a color filter 211, a protective layer 302, a first electrode 220, a dam 250, an organic light-emitting layer 360, and a second electrode 370 stacked sequentially.

[0139] The first sub-light-emitting region EA21 and the second light-emitting region EA22 of the second light-emitting region EA2 can have from Figure 3 The structure shown omits the color filter structure. For example, the first sub-light-emitting region EA21 and the second sub-light-emitting region EA22 of the second light-emitting region EA2 can have a structure in which the substrate 300, the insulating layer 301, the protective layer 302, the first electrode 220, the dam 250, the organic light-emitting layer 360 and the second electrode 370 are stacked in sequence.

[0140] Reference Figure 4 The display panel according to embodiments of the present disclosure includes multiple light-emitting areas.

[0141] like Figure 4 As shown, transistor 405 can be disposed on substrate 300.

[0142] At least one buffer layer may be disposed between the substrate 300 and the transistor 405.

[0143] Although not shown in the accompanying drawings, transistor 405 may include an active layer, a gate electrode, a source electrode, and a drain electrode. Furthermore, transistor 405 may include a driving transistor for driving an organic light-emitting element (OLED).

[0144] An insulating layer 301 may be disposed on a substrate 300 on which a transistor 405 is disposed.

[0145] The second color filter 212 may be disposed on the insulating layer 301. However, the color filter may not be disposed on the insulating layer 301 in the plurality of second light-emitting regions EA2.

[0146] The repair pattern 240 can be set on the second color filter 212.

[0147] The protective layer 302 can be disposed on the substrate 300 on which the second color filter 212 and the repair pattern 240 are disposed.

[0148] Multiple first electrodes 220 of an organic light-emitting element (OLED) can be disposed on a protective layer 302, and multiple connection patterns 230 can be disposed thereon.

[0149] The embankment 250 can be disposed on a protective layer 302 on which the first electrode 220 and the connecting pattern 230 are disposed.

[0150] The area with the dam 250 in the active region is the non-light-emitting area NEA of the display panel, and the area with the first electrode 220 but without the dam 250 is the light-emitting area EA.

[0151] The organic light-emitting layer 360 and the second electrode 370 can be sequentially disposed on the embankment 250 and the first electrode 220.

[0152] The connection pattern 230 can be disposed between at least two first electrodes 220 and can be electrically connected to at least two first electrodes 220.

[0153] The connection pattern 230 can be electrically connected to the transistor 405 disposed in the non-light-emitting area NEA through the contact holes CNT formed in the protective layer 302 and the insulating layer 301.

[0154] Specifically, one end of the connecting pattern 230 can be electrically connected to the first electrode 220 disposed in a sub-light-emitting region (the first sub-light-emitting region EA31 of the third light-emitting region), and the other end of the connecting pattern 230 can be electrically connected to the first electrode 220 disposed in another adjacent sub-light-emitting region (the second sub-light-emitting region EA32 of the third light-emitting region).

[0155] In other words, such as Figure 4 As shown, one end of a connecting pattern 230 can contact the first electrode 220 in the first sub-light-emitting region EA31 of the third light-emitting region EA3, and the other end can contact the first electrode 220 in the second sub-light-emitting region EA32 of the third light-emitting region EA3.

[0156] Due to the connection pattern 230, at least two sub-light-emitting regions EA31 and EA32 can be driven through a single circuit region.

[0157] A connection pattern 230 may have a structure for electrically connecting to a first electrode 220 disposed in each of at least two sub-emitting regions EA31 and EA32 that emit light of the same color.

[0158] The connection pattern 230 may include a material different from that of the first electrode 220.

[0159] For example, the connection pattern 230 may include a reflective conductive material. The connection pattern 230 may include one or an alloy of a metal selected from aluminum (Al), gold (Au), silver (Ag), copper (Cu), tungsten (W), molybdenum (Mo), chromium (Cr), tantalum (Ta), and titanium (Ti), but this disclosure is not limited thereto.

[0160] The connecting pattern 230 can be configured to overlap with at least one color filter.

[0161] The protective layer 302 may include holes 401 and 402 spaced apart from the contact holes CNT and formed in the non-light-emitting area NEA.

[0162] The protective layer 302 may include holes 401 and 402 overlapping with the color filter 212 in the region corresponding to the peripheral portion of the color filter 212.

[0163] The connection pattern 230 disposed on the protective layer 302 can be formed along the holes 401 and 402 formed in the protective layer 302. That is, the connection pattern 230 can also be disposed within the holes 401 and 402 of the protective layer 320.

[0164] The first electrode 220 disposed around the holes 401 and 402 in the protective layer 302 can be connected to the connection pattern 230. For example, a portion of the rear surface of the first electrode 220 can contact the connection pattern 230.

[0165] Meanwhile, some of the light emitted from the organic light-emitting element OLED may not be extracted from the substrate 300, but may travel to another adjacent sub-light-emitting area and be trapped inside the display panel, which will lead to a reduction in the light efficiency of the display panel.

[0166] In the display device according to the embodiments of this disclosure, since the connection pattern 230 including the reflective conductive material is provided along the holes 401 and 402 of the protective layer 302 formed on one side of the sub-light-emitting regions EA31 and EA32, the light emitted from the organic light-emitting element OLED will not travel to another adjacent sub-light-emitting region, and the direction of the light can be changed to a direction toward the substrate 300. That is, since the connection pattern 230 including the reflective conductive material is provided along the holes 401 and 402 of the protective layer 302 formed on one side of the sub-light-emitting regions EA31 and EA32, the connection pattern 230 can be a reflective pattern for changing the direction of light on at least one inclined surface of the holes 401 and 402.

[0167] For example, a portion of the light emitted from the first sub-emitting region EA31 of a third emitting region EA3 can pass through the first electrode 220, the protective layer 302, the second color filter 212, and the insulating layer 301 to be extracted from the substrate 300.

[0168] Another portion of the light emitted from the first sub-light-emitting region EA31 of the third light-emitting region EA3 can be reflected by the connection pattern 230 located in the first hole 401 of the protective layer 302 between the first sub-light-emitting region EA31 of the third light-emitting region EA3 and the circuit region for driving the first sub-light-emitting region EA31, so as to be extracted from the substrate 300.

[0169] Furthermore, another portion of the light emitted from the first sub-light-emitting region EA31 of the third light-emitting region EA3 can pass through the region corresponding to the second sub-light-emitting region EA32 of another adjacent third light-emitting region EA3 and can be reflected by the connection pattern 230 in the second hole 402 of the protective layer 302 located between the second sub-light-emitting region EA32 of another adjacent third light-emitting region EA3 and the circuit region for driving the second sub-light-emitting region EA32, so as to be extracted from the substrate 300.

[0170] As described above, since the first sub-light-emitting region EA31 of the third light-emitting region EA3 and the second sub-light-emitting region EA32 of another adjacent light-emitting region EA3 share a second color filter 212 and emit light of the same color, even when the light emitted from the first sub-light-emitting region EA31 of the third light-emitting region EA3 is emitted from the second sub-light-emitting region EA32 of another adjacent light-emitting region EA3 due to the connection pattern 230 provided in the second hole 402 of the protective layer 302, the effect of emitting light without color mixing can be obtained.

[0171] In other words, because the light emitted from the organic light-emitting element OLED travels from one sub-emitting region to another adjacent sub-emitting region, the problem of reduced light efficiency of the display panel can be prevented.

[0172] Furthermore, at least one repair pattern 240 may be disposed between at least two sub-light-emitting regions included in one light-emitting region. In this case, the repair pattern 240 may be disposed on the color filter.

[0173] Specifically, refer to Figure 4 The repair pattern 240 can be set between the second color filter 212 and the protective layer 302.

[0174] The repair pattern 240 is set in the non-luminous area NEA between the first sub-luminous area EA31 of a third luminous area EA3 and the second sub-luminous area EA32 of another adjacent third luminous area EA3.

[0175] Here, the material for repairing pattern 240 may include the material corresponding to that of connecting pattern 230. For example, repairing pattern 240 may include one of the metals selected from aluminum (Al), gold (Au), silver (Ag), copper (Cu), tungsten (W), molybdenum (Mo), chromium (Cr), tantalum (Ta), and titanium (Ti), or an alloy thereof, but this disclosure is not limited thereto.

[0176] The following will refer to Figures 5 to 9 Describe the process of manufacturing such a display panel.

[0177] Figures 5 to 9 A schematic diagram is shown, illustrating the formation Figure 2 The manufacturing process of the display panel shown.

[0178] First refer to Figure 5 Transistors 405 can be disposed on substrate 300.

[0179] An insulating layer 301 can be disposed on a substrate 300 on which transistor 405 is disposed.

[0180] A first color filter 211, a second color filter 212, and a third color filter 213 can be formed on the insulating layer 301.

[0181] Multiple repair patterns 240 can be provided on portions of the upper surfaces of the first to third color filters 211, 212, and 213. For example, such as Figure 5 As shown, a repair pattern 240 can be set on a color filter 211, 212 or 213.

[0182] At the same time, the color filter may not need to be placed in the second light-emitting area. In this case, such as Figure 5 As shown, the repair pattern 240 can be disposed on the insulating layer 301.

[0183] After that, as Figure 6As shown, a protective layer 302 can be provided on the substrate 300 on which the repair pattern 240 is provided.

[0184] Multiple contact holes (CNTs) can be formed in the protective layer 302.

[0185] The contact hole CNT formed in the protective layer 302 may expose a portion of the surface of the source electrode or drain electrode of a transistor (e.g., a driving transistor) included in the circuit region for driving each of the light-emitting regions EA1, EA2, EA3 and EA4.

[0186] Additionally, the protective layer 302 may include a plurality of holes 401 and 402 spaced apart from the contact hole CNT.

[0187] Multiple holes 401 and 402 can be formed as peripheral regions of sub-light-emitting regions EA11, EA12, EA21, EA22, EA31, EA32, EA41 and EA42 corresponding to light-emitting regions EA1, EA2, EA3 and EA4.

[0188] In the sub-light-emitting regions EA11, EA12, EA31, EA32, EA41 and EA42 of the first light-emitting region EA1, the third light-emitting region EA3 and the fourth light-emitting region EA4, multiple holes 401 and 402 can be formed as portions exposing the upper surfaces of color filters 211, 212 and 213.

[0189] In addition, in the sub-light-emitting regions EA21 and EA22 of the second light-emitting region EA2, multiple holes 401 and 402 can be formed to expose portions of the upper surface of the insulating layer 301 disposed below the protective layer 302.

[0190] After that, as Figure 7 As shown, a connection pattern 230 can be provided on the protective layer 302.

[0191] The connection pattern 230 can be formed inside each of the contact holes CNT, the first hole 401, and the second hole 402 in the protective layer 302.

[0192] The connecting pattern 230 can extend from the first sub-light-emitting regions EA11, EA21, EA31 and EA41 of the light-emitting regions EA1, EA2, EA3 and EA4 to the second sub-light-emitting regions EA12, EA22, EA32 and EA42 of the light-emitting regions EA1, EA2, EA3 and EA4 through the circuit regions of the light-emitting regions EA1, EA2, EA3 and EA4.

[0193] The connection pattern 230 can be set only in the non-emitting area NEA of the active area AA.

[0194] Next, as Figure 8 As shown, multiple first electrodes 220 of the organic light-emitting element can be disposed on the protective layer 302.

[0195] The first electrode 220 may overlap with the sub-light-emitting regions EA11, EA12, EA21, EA22, EA31, EA32, EA41 and EA42 of the light-emitting regions EA1, EA2, EA3 and EA4, and may also overlap with a portion of the non-light-emitting region NEA.

[0196] In the non-light-emitting region NEA, each of the first electrodes 220 can be connected to the connection pattern 230.

[0197] Therefore, as Figure 8 As shown, the first electrode 220 of the organic light-emitting element, which is configured to correspond to the sub-light-emitting region, can be electrically connected to the circuit region via the connection pattern 230.

[0198] After that, as Figure 9 As shown, the embankment 250 can be formed to correspond to the non-luminous region NEA.

[0199] The embankment 250 can be formed to overlap with the connecting pattern 230 and the repair pattern 240.

[0200] When foreign objects are generated on a display panel with this structure, the sub-light-emitting area is repaired by repair pattern 240, thereby preventing the visibility of the display panel from decreasing even when foreign objects are present.

[0201] The following will refer to Figures 10 to 12 Describe it.

[0202] Figure 10 It is shown that in Figure 2 A plan view showing the presence of foreign objects on the connection pattern in the structure, and Figure 11 A view illustrating a repair method in the case of foreign objects present on a connection pattern is shown. Figure 12 The illustration shows the explanation in having Figure 10 and Figure 11 The view shows the luminous state of the display panel after its structure has been repaired and the panel is driven.

[0203] Reference Figure 10 and Figure 11 During the manufacturing process of a display panel according to an embodiment of the present disclosure, a problem may occur in which foreign matter 1000 forms on the connection pattern 230.

[0204] When a foreign object 1000 is present on the connection pattern 230, the current is concentrated in the foreign object 1000, and therefore, bright spot defects may occur in the sub-light-emitting regions electrically connected to the connection pattern 230.

[0205] For example, when there is a foreign object 1000 on the connection pattern 230 in the area between the contact hole CNT in the Nth row and the first sub-light-emitting area EA31 of the third light-emitting area EA3, a bright spot defect may appear in the first sub-light-emitting area EA31 of the third light-emitting area EA3 in the Nth row.

[0206] In this case, such as Figure 11 As shown, a laser is irradiated in the direction from the rear surface of the substrate 300 toward the connection pattern 230 to cut off (disconnect) the connection pattern 230 provided in the Nth row (step 1).

[0207] In this case, the cutting position of the connecting pattern 230 can be the position between the foreign object 1000 in the Nth row and the first sub-light-emitting region EA31 of the third light-emitting region EA3.

[0208] As described above, by cutting the connection pattern 230, the organic light-emitting element OLED disposed in the first sub-light-emitting region EA31 of the third light-emitting region EA3 disposed in the Nth row can be electrically disconnected from the circuit region disposed in the Nth row.

[0209] Therefore, since it is impossible to supply voltage to the organic light-emitting element OLED disposed in the first sub-light-emitting region EA31 of the third light-emitting region EA3 disposed in the Nth row, the first sub-light-emitting region EA31 may not emit light even when the third light-emitting region EA3 in the Nth row is in the on state.

[0210] For example, refer to Figure 12 After the connecting pattern 230 is cut off, even when all the sub-light-emitting areas set in the Nth row are emitting light, the first sub-light-emitting area (the sub-light-emitting area located in the Nth row and the Mth column) of the third light-emitting area EA3 set in the Nth row may not emit light.

[0211] Therefore, as Figure 11 As shown, a laser is irradiated toward the repair pattern 240 toward the rear surface of the substrate 300 to weld the repair pattern 240 located at the boundary between the (N-1)th row and the Nth row, thereby connecting the repair pattern 240 to the first electrode 220 of the second sub-light-emitting region EA32 of the third light-emitting region EA3 in the (N-1)th row and the first electrode 220 of the first sub-light-emitting region EA31 of the third light-emitting region EA3 in the Nth row (step 2).

[0212] That is, the first sub-light-emitting region EA31 of the third light-emitting region EA3 in the Nth row can be electrically connected to the circuit region for driving the third light-emitting region EA3 through the first electrode 220 of the second sub-light-emitting region EA32 of the third light-emitting region EA3 in the (N-1)th row.

[0213] Therefore, as Figure 12 As shown, in the first sub-light-emitting region EA31 of the third light-emitting region EA3 located in the Nth row, the first sub-light-emitting region EA3 of the third light-emitting region EA3, which is connected to the circuit region of the third light-emitting region EA3 located in the (N-1)th row by a soldering process, can emit light when a voltage is applied to the (N-1)th row instead of the Nth row.

[0214] As described above, even when there is a foreign object 1000 on the connection pattern 230, defects in the specific sub-light-emitting area can be prevented and the specific sub-light-emitting area can be repaired.

[0215] In addition, such as Figures 2 to 12 As shown, in a display device according to an embodiment of the present disclosure, a light-emitting area may include at least two sub-light-emitting areas.

[0216] Even when a foreign object is present in the circuit area set in one row, at least two sub-light-emitting areas darken, and are then electrically connected to the circuit area set in another adjacent row, thereby repairing the darkened sub-light-emitting areas.

[0217] As described above, since a light-emitting area is divided into at least two sub-light-emitting areas, darkening and repair can be performed on at least one sub-light-emitting area.

[0218] Therefore, the first sub-light-emitting region EA31 of the third light-emitting region EA3 in the Nth row and Mth column can be darkened, and the first electrode 220 of the second sub-light-emitting region EA32 of the third light-emitting region EA3 in the (N-1)th row and Mth column can be electrically connected to the first electrode 220 of the first sub-light-emitting region EA31 of the third light-emitting region EA3 in the Nth row and Mth column through the repair pattern 240, so that when the third light-emitting region EA3 in the (N-1)th row and Mth column emits light, the first sub-light-emitting region EA31 of the third light-emitting region EA3 in the Nth row and Mth column can emit light.

[0219] Even if it is desired to emit light from the third light-emitting region EA3 located in the (N-1)th row and the Mth column, and it is not desired to drive the third light-emitting region EA3 located in the Nth row and the Mth column, when the third light-emitting region EA3 located in the (N-1)th row and the Mth column is driven, the repaired sub-light-emitting region located in the Nth row and the Mth column can also be driven simultaneously.

[0220] However, in the display panel according to the embodiments of the present disclosure, since a light-emitting area is divided into at least two sub-light-emitting areas, the area of ​​the repaired light-emitting area can be reduced.

[0221] For example, when a light-emitting area is not divided into multiple sub-light-emitting areas, or when multiple sub-light-emitting areas are not electrically connected by a connecting pattern, and when a foreign object is present in the circuit area located in the Nth row and Mth column, the entire third light-emitting area EA3 can be driven by the circuit area located in the (N-1)th row and Mth column. As described above, even when it is not desired to drive the Nth row and Mth column, the visibility of the display panel can be reduced because the entire third light-emitting area EA3 located in the Nth row and Mth column emits light.

[0222] On the other hand, in a display panel according to an exemplary embodiment of the present disclosure, when repair is performed due to foreign matter present in the circuit area provided in the Nth row and Mth column, since a portion of the third light-emitting area EA3 (i.e., a sub-light-emitting area) is driven by the circuit area provided in the (N-1)th row and Mth column, the light-emitting area with a relatively small area emits light even when it is not desired to drive the Nth row and Mth column, thereby improving the visibility of the display panel.

[0223] Figure 13 The illustration shows that when in having Figure 2 The diagram shows the structure of subpixels when there are foreign objects on the connection pattern of the display panel.

[0224] Reference Figure 13 Each sub-pixel SP in the organic light-emitting display panel PNL may further include: a scanning transistor SCAN, which transmits a data voltage Vdata to a first node N1 corresponding to the gate node of the driving transistor DRT; and a storage capacitor Cst, which holds the data voltage Vdata or the voltage corresponding to it for one frame.

[0225] A sub-pixel SP includes at least two organic light-emitting elements (OLEDs), each comprising a first electrode (anode or cathode), an organic layer including at least one light-emitting layer, and a second electrode (cathode or anode).

[0226] For example, a ground voltage EVSS can be applied to the second electrode of an organic light-emitting element (OLED).

[0227] The driving transistor DRT supplies driving current to the organic light-emitting element (OLED) to drive the OLED.

[0228] The driving transistor DRT has a first node N1, a second node N2, and a third node N3.

[0229] The term "node" in the context of nodes N1, N2, and N3 from the first node to the third node can refer to points, electrodes, or lines that have the same electrical state.

[0230] Each of the first node N1, the second node N2, and the third node N3 may include one or more electrodes.

[0231] The first node N1 of the driving transistor DRT can be a node corresponding to the gate node and can be electrically connected to the source node or drain node of the scanning transistor SCAN.

[0232] The second node N2 of the driving transistor DRT can be electrically connected to the first electrode 220 of the organic light-emitting element OLED, and can be a source node or a drain node.

[0233] The third node N3 of the driving transistor DRT can be a node to which the driving voltage EVDD is applied, can be electrically connected to the driving voltage line DVL that supplies the driving voltage EVDD, and can be a drain node or a source node.

[0234] The driving transistor DRT and the scanning transistor SCAN can be implemented as n-type or p-type.

[0235] The scanning transistor SCAN can be electrically connected between the data line DL and the first node N1 of the driving transistor DRT, and can be controlled by the scanning signal Scan applied to its gate node through the gate line.

[0236] The scanning transistor SCAN can be turned on by the scanning signal Scan to transmit the data voltage Vdata supplied from the data line DL to the first node N1 of the driving transistor DRT.

[0237] The storage capacitor Cst can be electrically connected between the first node N1 and the second node N2 of the driving transistor DRT.

[0238] The storage capacitor Cst is not a parasitic capacitor (e.g., Cgs or Cgd) existing as an internal capacitor between the first node N1 and the second node N2 of the driving transistor DRT, but is an external capacitor intentionally designed outside the driving transistor DRT.

[0239] The sensing transistor SENSE can be electrically connected between the second node N2 of the driving transistor DRT and the reference voltage line RVL, and can be controlled and turned on / off by the sensing signal Sense applied to its gate node.

[0240] The drain or source node of the sensing transistor SENSE can be electrically connected to the reference voltage line RVL, and the source or drain node of the sensing transistor SENSE can be electrically connected to the second node N2 of the driving transistor DRT.

[0241] For example, the sensing transistor SENSE can be turned on during the display driving period, and can also be turned on during the sensing driving period for the characteristic values ​​of the sensing driving transistor DRT or the characteristic values ​​of the organic light-emitting element OLED.

[0242] The sensing transistor SENSE can be turned on by the sensing signal Sense according to the corresponding drive timing (e.g., display drive timing or initialization timing during the sensing drive period), and can transmit the reference voltage Vref supplied to the reference voltage line RVL to the second node N2 of the driving transistor DRT.

[0243] Additionally, the sensing transistor SENSE can be turned on by the sensing signal Sense according to the corresponding driving timing (e.g., the sampling timing during the sensing driving period), and can transmit the voltage of the second node N2 of the driving transistor DRT to the reference voltage line RVL.

[0244] In other words, the sensing transistor SENSE can control the voltage state of the second node N2 of the driving transistor DRT, or can transmit the voltage of the second node N2 of the driving transistor DRT to the reference voltage line RVL.

[0245] Here, the reference voltage line RVL can be electrically connected to the ADC, which senses the voltage of the reference voltage line RVL and converts the sensed voltage into a digital value to output sensed data including the digital value.

[0246] The ADC can be included in the SDIC that implements the data driver DDR.

[0247] The sensing data output from the ADC can be used to sense the characteristic values ​​of the driving transistor DRT (e.g., threshold voltage or mobility) or the characteristic values ​​of the organic light-emitting element OLED (e.g., threshold voltage).

[0248] Each of the driving transistor DRT, the scanning transistor SCAN, and the sensing transistor SENSE can be an n-type transistor or a p-type transistor.

[0249] Meanwhile, the scan signal Scan and the sense signal Sense can be separate gate signals. In this case, the scan signal Scan and the sense signal Sense can be applied to the gate node of the scan transistor SCAN and the gate node of the sense transistor SENSE respectively through different gate lines.

[0250] In some cases, the scan signal Scan and the sense signal Sense can be the same gate signal. In this case, the scan signal Scan and the sense signal Sense can be applied together to the gate node of the scan transistor SCAN and the gate node of the sense transistor SENSE through the same gate line.

[0251] Figure 13 The structure of each subpixel shown is merely an example of the description, and in some cases, each subpixel may also include one or more transistors or one or more storage capacitors.

[0252] Alternatively, multiple subpixels can have the same structure, or some of the multiple subpixels can have different structures.

[0253] Additionally, as referenced Figures 10 to 12 As stated, when a foreign object is present on the connection pattern set in the Nth row, one of the at least two organic light-emitting elements (OLEDs) set in the Nth row can be cut off to prevent bright spot defects.

[0254] Reference Figures 2 to 13 The main description focuses on the structure of a light-emitting region EA comprising two sub-light-emitting regions, but the structure of embodiments of this disclosure is not limited thereto.

[0255] like Figures 14 to 23 As shown, a light-emitting region may include at least four sub-light-emitting regions.

[0256] Figure 14 This is a schematic plan view showing the structure of a portion of the active region in a display panel according to other embodiments of the present disclosure.

[0257] In the following description, content overlapping with the above embodiments (structure, effects, etc.) may be omitted. Furthermore, in the following description, the same reference numerals may be used for components that overlap with those of the above embodiments.

[0258] Reference Figure 14 In other embodiments of the present disclosure, the active area AA of the display panel may include a plurality of light-emitting areas EA1, EA2, EA3 and EA4 and a non-light-emitting area NEA surrounding the light-emitting areas EA1, EA2, EA3 and EA4.

[0259] The multiple light-emitting regions EA1, EA2, EA3 and EA4 may include the first light-emitting region EA1, the second light-emitting region EA2, the third light-emitting region EA3 and the fourth light-emitting region EA4.

[0260] The first light-emitting region EA1 may include the first sub-light-emitting region to the fourth sub-light-emitting region EA11, EA12, EA13 and EA14; the second light-emitting region EA2 may include the first sub-light-emitting region to the fourth sub-light-emitting region EA21, EA22, EA23 and EA24; the third light-emitting region EA3 may include the first sub-light-emitting region to the fourth sub-light-emitting region EA31, EA32, EA33 and EA34; and the fourth light-emitting region EA4 may include the first sub-light-emitting region to the fourth sub-light-emitting region EA41, EA42, EA43 and EA44.

[0261] Each of the light-emitting areas EA1, EA2, EA3 and EA4 includes multiple sub-light-emitting areas that can be set separately from each other.

[0262] For example, such as Figure 14 As shown, the first to fourth sub-light-emitting regions EA11, EA12, EA13, and EA14 included in the first light-emitting region EA1 can be arranged separately from each other. Similarly, the first to fourth sub-light-emitting regions EA21, EA22, EA23, and EA24 included in the second light-emitting region EA2 can be arranged separately from each other, and the first to fourth sub-light-emitting regions EA31, EA32, EA33, and EA34 included in the third light-emitting region EA3 can be arranged separately from each other. Furthermore, the first to fourth sub-light-emitting regions EA41, EA42, EA43, and EA44 included in the fourth light-emitting region EA4 can also be arranged separately from each other.

[0263] Each of the first to fourth light-emitting regions EA1, EA2, EA3 and EA4, which include multiple sub-light-emitting regions, can be driven by a circuit region.

[0264] Multiple light-emitting regions EA1, EA2, EA3 and EA4 can be set in multiple rows and columns of the active region AA.

[0265] In one row of the active region AA, the first light-emitting region EA1 may include a first sub-light-emitting region EA11 and a third sub-light-emitting region EA13 disposed in the first sub-row and spaced apart from each other. The first light-emitting region EA1 may also include a second sub-light-emitting region EA12 and a fourth sub-light-emitting region EA14 disposed in a second sub-row adjacent to the first sub-row and spaced apart from each other. The circuit region for driving the first light-emitting region EA1 may be disposed between the first sub-light-emitting regions EA11 and EA13 and the second and fourth light-emitting regions EA12 and EA14.

[0266] In addition, such as Figure 14As shown, the second to fourth light-emitting regions EA2, EA3 and EA4 can also have a structure corresponding to the structure of the first light-emitting region EA1.

[0267] Each of the circuit regions used to drive the light-emitting regions EA1, EA2, EA3 and EA4 may include at least one connection pattern 230.

[0268] Connection pattern 230 can be used to electrically connect the sub-light-emitting areas of each of the light-emitting areas EA1, EA2, EA3 and EA4 to the circuit area.

[0269] The connection pattern 230 can be electrically connected to a transistor located in the circuit area through a contact hole CNT, which is formed in an insulating layer disposed below the connection pattern 230.

[0270] Additionally, the connection pattern 230 may include: a first connection pattern 1431 connected to the first sub-light-emitting regions EA11, EA21, EA31 and EA41; a second connection pattern 1432 connected to the second sub-light-emitting regions EA12, EA22, EA32 and EA42; a third connection pattern 1433 connected to the third sub-light-emitting regions EA13, EA23, EA33 and EA43; and a fourth connection pattern 1434 connected to the fourth sub-light-emitting regions EA14, EA24, EA34 and EA44.

[0271] As described above, the first to fourth connection patterns 1431, 1432, 1433 and 1434 can be electrically connected to the sub-light-emitting areas, so that the first to fourth light-emitting areas EA1, EA2, EA3 and EA4, which include multiple sub-light-emitting areas, can be driven by a single circuit area.

[0272] The connecting pattern 230 may include a region 1451 (hereinafter referred to as the first region), which is integrally formed with the first connecting pattern 1431 and the third connecting pattern 1433, and is disposed on one side of the first sub-light-emitting region and the third sub-light-emitting region in the first sub-row of each of the light-emitting regions EA1, EA2, EA3, and EA4. Additionally, the connecting pattern 230 may include a region 1452 (hereinafter referred to as the second region), which is integrally formed with the second connecting pattern 1432 and the fourth connecting pattern 1434, and is disposed on one side of the second sub-light-emitting region and the fourth sub-light-emitting region in the second sub-row of each of the light-emitting regions EA1, EA2, EA3, and EA4.

[0273] Furthermore, the connecting pattern 230 may include at least one reflective pattern 1450, which is disposed between adjacent sub-light-emitting regions in the same sub-row of each of the light-emitting regions. Specifically, in the same sub-row, the reflective pattern 1450 may be disposed between sub-light-emitting regions emitting the same color of light. The reflective pattern 1450 may be integrally formed with the first region 1451 or may be integrally formed with the second region 1452.

[0274] For example, such as Figure 14 As shown, at least one reflective pattern 1450 may be disposed between the first sub-light-emitting region EA11 and the third sub-light-emitting region EA13 disposed in the first sub-row of the first light-emitting region EA1.

[0275] In addition, at least one reflective pattern 1450 may be disposed between the second sub-light-emitting region EA12 and the fourth sub-light-emitting region EA14 disposed in the second sub-row of the first light-emitting region EA1.

[0276] The reflective pattern 1450 can also be applied to the second to fourth light-emitting regions EA2, EA3 and EA4 in a structure corresponding to the structure of the first light-emitting region EA1.

[0277] In other words, the connection pattern 230 may include the first connection pattern to the fourth connection pattern 1431, 1432, 1433 and 1434, the first region 1451, the second region 1452 and the reflection pattern 1450.

[0278] The following will refer to Figure 15 and Figure 16 Describe this structure in detail.

[0279] Figure 15 It is along Figure 14 The cross-sectional view of line GH, and Figure 16 It is along Figure 14 A cross-sectional view of line IJ.

[0280] Specifically, Figure 15 It is a cross-sectional view in the row direction, which shows the first sub-light-emitting region EA31 and the third sub-light-emitting region EA33 of the third light-emitting region EA3, and the first sub-light-emitting region EA41 and the third sub-light-emitting region EA43 of the fourth light-emitting region EA4 adjacent to the third light-emitting region EA3.

[0281] Figure 16 This is a cross-sectional view in the column direction, showing the first sub-light-emitting region EA31 and the second sub-light-emitting region EA32 of the third light-emitting region EA3, as well as the circuit region included in the non-light-emitting region NEA.

[0282] In the following description, content overlapping with the above embodiments (structure, effects, etc.) may be omitted. Furthermore, in the following description, the same reference numerals may be used for components that overlap with those of the above embodiments.

[0283] First, refer to Figure 15 An insulating layer 301 can be disposed on a substrate 300, a second color filter 212 and a third color filter 213 can be disposed on the insulating layer 301, and a protective layer 302 can be disposed on the second color filter 212 and the third color filter 213.

[0284] Multiple first electrodes 220, configured to correspond to sub-light-emitting regions EA31, EA33, EA41, and EA43, can be disposed on the protective layer 302.

[0285] Additionally, the protective layer 302 may include one or more third holes 1501 formed therein.

[0286] The third aperture 1501 can be formed between sub-emitting regions that emit light of the same color.

[0287] A reflection pattern 1450 can be set in the third hole 1501.

[0288] The reflective pattern 1450 may include a reflective conductive material. For example, the reflective pattern 1450 may include a metal selected from aluminum (Al), gold (Au), silver (Ag), copper (Cu), tungsten (W), molybdenum (Mo), chromium (Cr), tantalum (Ta), and titanium (Ti), or an alloy thereof, but this disclosure is not limited thereto.

[0289] A portion of the reflective pattern 1450 disposed between the first sub-light-emitting region EA31 and the third sub-light-emitting region EA33 of the third light-emitting region EA3 can contact a portion of the first electrode 220 disposed in the first sub-light-emitting region EA31 of the third light-emitting region EA3, and another portion of the reflective pattern 1450 can contact a portion of the first electrode 220 disposed in the third sub-light-emitting region EA33 of the third light-emitting region EA3.

[0290] In addition, a portion of the reflective pattern 1450 disposed between the first sub-light-emitting region EA41 and the third sub-light-emitting region EA43 of the fourth light-emitting region EA4 can contact a portion of the first electrode 220 disposed in the first sub-light-emitting region EA41 of the fourth light-emitting region EA4, and another portion of the reflective pattern 1450 can contact a portion of the first electrode 220 disposed in the third sub-light-emitting region EA43 of the fourth light-emitting region EA4.

[0291] As described above, since the reflective pattern 1450 is disposed between sub-emitting regions that emit light of the same color, a portion of the light emitted from the sub-emitting regions reaches the reflective pattern 1450 and is reflected toward the substrate 300, thereby increasing the amount of light extracted from the substrate 300.

[0292] In addition, the embankment 250 can be disposed on the protective layer 302 on which the first electrode 220 and the reflective pattern 1450 are provided.

[0293] The organic light-emitting layer 360 and the second electrode 370 can be sequentially disposed on the substrate 300 on which the embankment 250 is provided.

[0294] Meanwhile, the reflective pattern 1450 can overlap with the embankment 250.

[0295] A portion of the reflective pattern 1450 that contacts the first electrode 220 may be located in the non-light-emitting region NEA. Therefore, the reflective pattern 1450 has the effect of improving light extraction efficiency without reducing the area of ​​the light-emitting region.

[0296] like Figure 16 As shown, transistor 405 can be disposed on substrate 300.

[0297] The insulating layer 301 and the second color filter 212 can be sequentially disposed on the substrate 300 on which the transistor 405 is disposed, and the protective layer 302 can be disposed on the insulating layer 301 on which the color filter 212 is disposed.

[0298] Multiple first electrodes 220 of an organic light-emitting element (OLED) can be disposed on a protective layer 302, and multiple connection patterns 230 can be disposed thereon.

[0299] The embankment 250 can be disposed on the protective layer 302 on which the first electrode 220 and the connecting pattern 230 are provided.

[0300] The organic light-emitting layer 360 and the second electrode 370 can be sequentially disposed on the embankment 250 and the first electrode 220.

[0301] One end of the connecting pattern 230 can be electrically connected to the first electrode 220 disposed in a sub-light-emitting region (the first sub-light-emitting region EA31 of the third light-emitting region), and the other end of the connecting pattern 230 can be electrically connected to the first electrode 220 disposed in another adjacent sub-light-emitting region (the second sub-light-emitting region EA32 of the third light-emitting region).

[0302] In other words, such as Figure 16 As shown, one end of a connection pattern 230 (corresponding to) Figure 14The first connecting pattern 230 can contact the first electrode 220 in the first sub-light-emitting region EA31 of the third light-emitting region EA3, and the other end of the connecting pattern 230 (corresponding to) Figure 14 The third connecting pattern can contact the first electrode 220 in the second sub-light-emitting region EA32 of the third light-emitting region EA3.

[0303] The protective layer 302 may include holes 401 and 402 spaced apart from the contact holes CNT and formed in the non-light-emitting area NEA.

[0304] The connection pattern provided in the contact hole CNT can be extended to be provided in the holes 401 and 402 of the protective layer 302.

[0305] The first electrode 220 disposed around the holes 401 and 402 of the protective layer 302 can be connected to the connection pattern 230. For example, a portion of the rear surface of the first electrode 220 can contact the connection pattern 230.

[0306] The connection pattern 230 not only enables the multiple sub-light-emitting regions EA31 and EA32 to be driven through a single circuit region, but also allows light captured inside the display panel to be extracted from the substrate 300 through the connection pattern 230 disposed in the holes 401 and 402 of the protective layer 302. That is, since the connection pattern 230 is disposed along the holes 401 and 402 of the protective layer 302 formed on one side of the sub-light-emitting regions EA31 and EA32, the connection pattern 230 can be a reflective pattern that alters the direction of light on at least one inclined surface of the holes 401 and 402.

[0307] Figure 17 and Figure 18 It shows where defects appear in... Figure 14 The view that normalizes the display panel is an example of the structure of the display panel.

[0308] First, refer to Figure 17 When a foreign object 1700 is present on at least one connection pattern (e.g., a first connection pattern 1431 connected to a first sub-light-emitting region EA11 of a first light-emitting region EA1), the connection pattern on which the foreign object 1700 is present can be cut off by a laser.

[0309] like Figure 17 As shown, the first electrode 220 disposed in the first sub-light-emitting region EA11 of the first light-emitting region EA1 can be in a state where it is electrically connected to the first electrode 220 disposed in the third sub-light-emitting region EA13 of the first light-emitting region EA1 disposed in the same sub-row via the reflection pattern 1450.

[0310] Therefore, even when the first connection pattern 1431 is cut off, when the first light-emitting area EA1 is in the on state, the voltage supplied from the circuit area can be applied to the first sub-light-emitting area EA11 of the first light-emitting area EA1 through the third connection pattern 1433, the first electrode of the third sub-light-emitting area EA13 and the reflection pattern 1450.

[0311] Therefore, it can prevent visibility from decreasing due to the lack of light emission in the sub-luminescent region.

[0312] In addition, such as Figure 18 As shown, when a defect appears in the first sub-light-emitting region EA11 of the first light-emitting region EA1 due to foreign objects, etc., the connecting pattern 230 and the reflection pattern 1450 located between the first sub-light-emitting region EA11 and the third sub-light-emitting region EA13 of the first light-emitting region EA1 are cut off by laser, thereby preventing the defect from appearing in the first sub-light-emitting region EA11 of the first light-emitting region EA1.

[0313] As described above, even when a sub-light-emitting area is disconnected from the circuit area, since a light-emitting area is divided into at least four sub-light-emitting areas, the non-light-emitting area is reduced to 1 / 4 of the area where a light-emitting area is completely disconnected and therefore does not emit light, thereby improving the visibility of the display panel.

[0314] Additionally, through having Figures 14 to 16 Adding a repair pattern to the display panel of the structure allows the sub-light-emitting area to be repaired even when foreign objects are generated.

[0315] The following will refer to Figures 19 to 22 This will be described.

[0316] Figure 19 It shows where the repair pattern is added to Figure 14 A view of the structure of the structure. Figure 20 It is along Figure 19 A cross-sectional view of line KL. Figure 21 The illustration shows that when there is Figure 19 and Figure 20 The view shows the luminous state of the display panel before and after it was repaired and when it was driven.

[0317] Figure 19 The structure can be compared with the reference Figure 14 The first to fourth light-emitting regions EA1, EA2, EA3 and EA4, as well as the non-light-emitting region NEA, have the same structure.

[0318] However, as Figure 19As shown, the display panel according to an embodiment of the present disclosure may further include a repair pattern 1940 disposed between the light-emitting areas disposed in the (N-1)th row and the Nth row.

[0319] Specifically, the repair pattern 1940 can be set between the first light-emitting area EA1 set in the (N-1)th row and the first light-emitting area EA1 set in the Nth row.

[0320] A repair pattern 1940 may overlap with a reflective pattern 1450 arranged in the (N-1)th row, and may also overlap with a reflective pattern 1450 arranged in the Nth row.

[0321] For example, such as Figure 19 As shown, a portion of a repair pattern 1940 may overlap with a reflection pattern 1450 disposed between the second sub-light-emitting region EA12 and the fourth sub-light-emitting region EA14 of the first light-emitting region EA1 disposed in the (N-1)th row, and may also overlap with a reflection pattern 1450 disposed between the first sub-light-emitting region EA11 and the third sub-light-emitting region EA13 of the first light-emitting region EA1 disposed in the Nth row. In this case, a repair pattern 1940 may also overlap with a first color filter 211.

[0322] Additionally, a portion of another repair pattern 1940 may overlap with the reflection pattern 1450 between the second sub-light-emitting region EA22 and the fourth sub-light-emitting region EA24 of the second light-emitting region EA2 set in the (N-1) row, and may also overlap with the reflection pattern 1450 between the first sub-light-emitting region EA21 and the third sub-light-emitting region EA23 of the second light-emitting region EA2 set in the N row.

[0323] In addition, such as Figure 19 and Figure 20 As shown, a portion of another repair pattern 1940 may overlap with a reflective pattern 1450 disposed between the second sub-emitting region EA32 and the fourth sub-emitting region EA34 of the third emitting region EA3 located in the (N-1)th row, and may also overlap with a reflective pattern 1450 disposed between the first sub-emitting region EA31 and the third sub-emitting region EA33 of the third emitting region EA3 disposed in the Nth row. In this case, a repair pattern 1940 may also overlap with a second color filter 212.

[0324] like Figure 19As shown, a portion of another repair pattern 1940 may overlap with the reflection pattern 1450 disposed between the second sub-emitting region EA42 and the fourth sub-emitting region EA44 of the fourth emitting region EA4 disposed in the (N-1)th row, and may also overlap with the reflection pattern 1450 disposed between the first sub-emitting region EA41 and the third sub-emitting region EA43 of the fourth emitting region EA4 disposed in the Nth row. In this case, a repair pattern 1940 may also overlap with a third color filter 213.

[0325] like Figure 20 As shown, the repair pattern 1940 can be disposed on the protective layer 302. The reflective pattern 1450 can be disposed below the protective layer 302.

[0326] At the same time, Figure 19 In the structure of the display panel shown, when there is a foreign object on a connection pattern 230, the sub-light-emitting area connected to the connection pattern 230 can usually be operated by cutting the connection pattern 230 and repairing it with the repair pattern 1940.

[0327] For example, when located in Figure 21 When there are foreign objects on the first connection pattern 1431 and the third connection pattern 1433 in the connection pattern 230 of the Nth row and Mth column that connect to the first sub-light-emitting area EA31 and the third sub-light-emitting area EA33 of the third light-emitting area EA3, in order to prevent bright spot defects from appearing in the first sub-light-emitting area EA31 and the third sub-light-emitting area EA33 of the third light-emitting area EA3, the first connection pattern 1431 and the third connection pattern 1433 can be disconnected from the circuit area using a laser (step 1).

[0328] In this case, such as Figure 21 As shown, even when a signal is applied to the Nth row, the first sub-light-emitting region EA31 and the third sub-light-emitting region EA33 of the third light-emitting region EA3 located in the Nth row and the Mth column will not emit light.

[0329] Subsequently, in order to repair the first sub-light-emitting region EA31 and the third sub-light-emitting region EA33 of the third light-emitting region EA3, as follows: Figure 19 and Figure 20 As shown, a laser can be irradiated onto the following repair pattern 1940, which overlaps with the second sub-light-emitting region EA32 and the fourth sub-light-emitting region EA34 of the third light-emitting region EA3 located in the (N-1)th row and the Mth column, and the first sub-light-emitting region EA31 and the third sub-light-emitting region EA33 of the third light-emitting region EA3 located in the Nth row and the Mth column.

[0330] After laser irradiation Figure 20The repair pattern 1940 shown can be connected to the reflective pattern 1450 located below the repair pattern 1940.

[0331] Since the first electrode 220, which is configured to correspond to the second sub-light-emitting region EA32 and the fourth sub-light-emitting region EA34 of the third light-emitting region EA3 located in the (N-1)th row and the Mth column, is in contact with the repair pattern 1940, the first sub-light-emitting region EA31 and the third sub-light-emitting region EA33 of the third light-emitting region EA3 located in the Nth row and the Mth column can be electrically connected to the circuit area for driving the third light-emitting region EA3 located in the (N-1)th row and the Mth column, wherein the repair pattern 1940 overlaps with the second sub-light-emitting region EA32 and the fourth sub-light-emitting region EA34 of the third light-emitting region EA3 located in the (N-1)th row and the Mth column, as well as the first sub-light-emitting region EA31 and the third sub-light-emitting region EA33 of the third light-emitting region EA3 located in the Nth row and the Mth column.

[0332] Therefore, as Figure 21 As shown, after the repair is performed (after step 2), when the third light-emitting region EA3 in the (N-1)th row and Mth column is driven, the first sub-light-emitting region EA31 and the third sub-light-emitting region EA3 in the Nth row and Mth column can also be driven.

[0333] That is, even when foreign objects are generated on the connection pattern 230, all sub-light-emitting areas can emit light, and there are no sub-light-emitting areas that do not emit light.

[0334] Already referred to Figures 19 to 21 The main description is of a structure in which a repair pattern 1940 is set for every four sub-luminescent regions, but the implementation of this disclosure is not limited thereto.

[0335] Figure 22 It is shown that in Figure 14 The view shows a structure in which two repair patterns are set in every four sub-luminescent regions. Figure 23 It is along Figure 22 A cross-sectional view of line MN. Figure 24 The illustration shows that when there is Figure 22 and Figure 23 The view shows the luminous state of the display panel before and after it was repaired and when it was driven.

[0336] Figure 22 The structure can be compared with the reference Figure 14 The non-luminescent region NEA and each of the first to fourth luminescent regions EA1, EA2, EA3 and EA4 have the same structure.

[0337] However, as Figure 22 As shown, the display panel according to the embodiments of the present disclosure may further include a first repair pattern 2241 and a second repair pattern 2242, which are disposed between the light-emitting areas disposed in the (N-1)th row and the Nth row.

[0338] Specifically, the first repair pattern 2241 and the second repair pattern 2242 can be set between the first light-emitting area EA1 set in the (N-1)th row and the first light-emitting area EA1 set in the Nth row.

[0339] A portion of the first repair pattern 2241 that overlaps with the first color filter 211 may overlap with a portion of the first electrode 220 corresponding to the second sub-light-emitting region EA12 of the first light-emitting region EA1 located in the (N-1)th row and the Mth column. Another portion of the first repair pattern 2241 that overlaps with the first color filter 211 may overlap with a portion of the first electrode 220 corresponding to the first sub-light-emitting region EA11 of the first light-emitting region EA1 located in the Nth row and the Mth column.

[0340] Furthermore, a portion of the second repair pattern 2242 that overlaps with the first color filter 211 may overlap with a portion of the first electrode 220 corresponding to the fourth sub-light-emitting region EA14 of the first light-emitting region EA1 located in the (N-1)th row and the Mth column. Another portion of the second repair pattern 2242 that overlaps with the first color filter 211 may overlap with a portion of the first electrode 220 corresponding to the third sub-light-emitting region EA13 of the first light-emitting region EA1 located in the Nth row and the Mth column.

[0341] A portion of a first repair pattern 2241 in the non-luminous region NEA surrounding the second luminous region EA2 may overlap with a portion of a first electrode 220 corresponding to the second sub-luminous region EA22 of the second luminous region EA2 located in the (N-1)th row and the Mth column. Another portion of the first repair pattern 2241 overlapping with the first color filter 211 may overlap with a portion of the first electrode 220 corresponding to the first sub-luminous region EA21 of the second luminous region EA2 located in the Nth row and the Mth column.

[0342] Additionally, a portion of a second repair pattern 2242 located in the non-light-emitting region NEA surrounding the second light-emitting region EA2 may overlap with a portion of a first electrode 220 corresponding to the fourth sub-light-emitting region EA24 of the second light-emitting region EA2 located in the (N-1)th row and Mth column. Another portion of the second repair pattern 2242 may overlap with a portion of a first electrode 220 corresponding to the third sub-light-emitting region EA23 of the second light-emitting region EA2 located in the Nth row and Mth column.

[0343] A portion of the first repair pattern 2241 that overlaps with the second color filter 212 may overlap with a portion of the first electrode 220 corresponding to the second sub-light-emitting region EA32 of the third light-emitting region EA3 located in the (N-1)th row and the Mth column. Another portion of the first repair pattern 2241 that overlaps with the second color filter 212 may overlap with a portion of the first electrode 220 corresponding to the first sub-light-emitting region EA31 of the third light-emitting region EA3 located in the Nth row and the Mth column.

[0344] Furthermore, a portion of the second repair pattern 2242 that overlaps with the second color filter 212 may overlap with a portion of the first electrode 220 corresponding to the fourth sub-light-emitting region EA34 of the third light-emitting region EA3 located in the (N-1)th row and the Mth column. Another portion of the second repair pattern 2242 that overlaps with the second color filter 212 may overlap with a portion of the first electrode 220 corresponding to the third sub-light-emitting region EA33 of the third light-emitting region EA3 located in the Nth row and the Mth column.

[0345] A portion of the first repair pattern 2241 that overlaps with the third color filter 213 may overlap with a portion of the first electrode 220 corresponding to the second sub-light-emitting region EA42 of the fourth light-emitting region EA4 located in the (N-1)th row and the Mth column. Another portion of the first repair pattern 2241 that overlaps with the third color filter 213 may overlap with a portion of the first electrode 220 corresponding to the first sub-light-emitting region EA41 of the fourth light-emitting region EA4 located in the Nth row and the Mth column.

[0346] Furthermore, a portion of the second repair pattern 2242 that overlaps with the third color filter 213 may overlap with a portion of the first electrode 220 corresponding to the fourth sub-light-emitting region EA44 of the fourth light-emitting region EA4 located in the (N-1)th row and the Mth column. Another portion of the second repair pattern 2242 that overlaps with the third color filter 213 may overlap with a portion of the first electrode 220 corresponding to the third sub-light-emitting region EA43 of the fourth light-emitting region EA4 located in the Nth row and the Mth column.

[0347] like Figure 23 As shown, the first repair pattern 2241 and the second repair pattern 2242 can be disposed below the protective layer 302. The first electrode 220, configured to correspond to each sub-light-emitting region, can be disposed on the protective layer 302.

[0348] At the same time, Figure 22In the structure of the display panel shown, when there is a foreign object on a connection pattern 230, the sub-light-emitting area connected to the connection pattern 230 can usually be operated by cutting the connection pattern 230 and repairing it using the first repair pattern 2241 or the second repair pattern 2242.

[0349] For example, when a foreign object is present on the first connection pattern 1431 of the connection pattern 230 located in the Nth row and Mth column, which is connected to the first sub-light-emitting region EA31 of the third light-emitting region EA3, a bright spot defect may appear in the first sub-light-emitting region EA31 of the third light-emitting region EA3. To prevent the bright spot defect, a laser can be used to disconnect the first connection pattern 1431 from the circuit area (step 1).

[0350] In this case, such as Figure 24 As shown, even when a signal is applied to the Nth row, the first sub-light-emitting region EA31 of the third light-emitting region EA3 in the Nth row and Mth column will not emit light.

[0351] Subsequently, in order to repair the first sub-emitting region EA31 of the third emitting region EA3, such as Figure 22 and Figure 23 As shown, a laser can be irradiated onto a first repair pattern 2241, which overlaps with each of the first electrode 220 configured to correspond to the second sub-light-emitting region EA32 of the third light-emitting region EA3 located in the (N-1)th row and the Mth column, and the first electrode 220 configured to correspond to the first sub-light-emitting region EA31 of the third light-emitting region EA3 located in the Nth row and the Mth column.

[0352] After laser irradiation Figure 23 The first repair pattern 2241 shown can be connected to the first electrode 220 disposed on the first repair pattern 2241.

[0353] Since the first electrode 220, which is configured to correspond to the second sub-light-emitting region EA32 of the third light-emitting region EA3 located in the (N-1)th row and the Mth column, and the first electrode 220, which is configured to correspond to the first sub-light-emitting region EA31 of the third light-emitting region EA3 located in the Nth row and the Mth column, are in contact with the repair pattern 2241, the first sub-light-emitting region EA31 of the third light-emitting region EA3 located in the Nth row and the Mth column can be electrically connected to the circuit area for driving the third light-emitting region EA3 located in the (N-1)th row and the Mth column.

[0354] Therefore, as Figure 24As shown, after the repair is performed (after step 2), when the third light-emitting region EA3 in the (N-1)th row and the Mth column is driven, the first sub-light-emitting region EA31 in the third light-emitting region EA3 in the Nth row and the Mth column can also be driven.

[0355] That is, even when foreign objects are generated on the connecting pattern 230, since a light-emitting area is divided into at least four sub-light-emitting areas and the area of ​​each sub-light-emitting area is smaller than the area of ​​a light-emitting area, the possibility of reduced visibility can be reduced even when the sub-light-emitting areas set in the corresponding row are repaired to emit light when another adjacent row is in the on state.

[0356] Meanwhile, although the above embodiments have mainly described the structure in which the display panel according to the present disclosure includes a first light-emitting region to a fourth light-emitting region EA1, EA2, EA3 and EA4 that emits light of different colors, the present disclosure is not limited thereto, and can also be applied to a structure in which the display panel includes at least two light-emitting regions that emit light of different colors.

[0357] The above-described embodiments of this disclosure will be briefly described below.
