However, the present disclosure is not limited to the exemplary embodiments disclosed herein, but will be implemented in various forms. The exemplary embodiments are provided only by way of example so that those skilled in the art can fully understand the disclosure of the present disclosure and the scope of the present disclosure.

[0036] The shapes, sizes, ratios, angles, quantities, etc. illustrated in the drawings used to describe the exemplary embodiments of the present disclosure are merely examples, and the present disclosure is not limited thereto. The same reference numerals generally represent the same elements throughout the specification. In addition, in the following description of the present disclosure, detailed explanations of known related technologies may be omitted to avoid unnecessarily obscuring the subject matter of the present disclosure.

[0041] Like reference numbers generally refer to like elements throughout the specification.

[0042] The sizes and thicknesses of various components illustrated in the drawings are illustrated for convenience of description, and the present disclosure is not limited to the sizes and thicknesses of the components illustrated.

[0043] The features of the various embodiments of the present disclosure may be partially or entirely coupled or combined with each other, and may be technically associated and operated in various ways, and the embodiments may be implemented independently of each other or in association with each other.

[0044] Hereinafter, a display device according to exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0045] Figure 1 is a schematic diagram of a display device according to an exemplary embodiment of the present disclosure. Figure 1 In the present invention, for the convenience of description, among the components of the display device 100, only the display panel PN, the gate driver GD, the data driver DD, and the timing controller TC are illustrated.

[0046] Reference Figure 1 , the display device 100 includes a display panel PN having a plurality of sub-pixels SP, a gate driver GD and a data driver DD supplying various signals to the display panel PN, and a timing controller TC controlling the gate driver GD and the data driver DD.

[0047] The gate driver GD supplies a plurality of scan signals to the plurality of scan lines SL according to a plurality of gate control signals supplied from the timing controller TC. Figure 1 2 and 3. It is shown that one gate driver GD is disposed to be spaced apart from one side of the display panel PN, but the number of the gate drivers GD and the arrangement thereof are not limited thereto.

[0048] The data driver DD converts the image data input from the timing controller TC into data voltages using reference gamma voltages according to a plurality of data control signals supplied from the timing controller TC. The data driver DD may supply the converted data voltages to a plurality of data lines DL.

[0049] The timing controller TC aligns the image data input from the outside to supply the image data to the data driver DD. The timing controller TC can generate a gate control signal and a data control signal using a synchronization signal (e.g., a dot clock signal, a data enable signal, and a horizontal / vertical synchronization signal) input from the outside. The timing controller TC provides the generated gate control signal and data control signal to the gate driver GD and the data driver DD, respectively, to control the gate driver GD and the data driver DD.

[0050] The display panel PN is a configuration that displays an image to a user and includes a plurality of sub-pixels SP. The plurality of sub-pixels SP may include a first sub-pixel SP1, a second sub-pixel SP2, and a shared sub-pixel SP'. The shared sub-pixel SP' may be disposed between the first sub-pixel SP1 and the second sub-pixel SP2. At this time, the first sub-pixel SP1, the second sub-pixel SP2, and the shared sub-pixel SP' may emit light having the same color. That is, all of the first sub-pixels SP1, the second sub-pixel SP2, and the shared sub-pixel SP' may be sub-pixels for emitting red light, or sub-pixels for emitting green light, or sub-pixels for emitting blue light.

[0051] In the display panel PN, a plurality of scan lines SL and a plurality of data lines DL intersect each other and each of a first sub-pixel SP1, a second sub-pixel SP2 and a shared sub-pixel SP' among a plurality of sub-pixels SP is connected to the scan line SL and the data line DL. The shared sub-pixel SP' may not be connected to the scan line SL and the data line DL. In addition, although not shown in the drawings, each of the plurality of sub-pixels SP may be connected to a high potential power line, a low potential power line, a reference line, etc.

[0052] In the display panel PN, a display area AA and a non-display area NA surrounding the display area AA may be defined.

[0053] The display area AA is an area in which an image is displayed in the display device 100. In the display area AA, a plurality of sub-pixels SP constituting a plurality of pixels PX and a circuit for driving the plurality of sub-pixels SP may be provided. The plurality of sub-pixels SP are the smallest units constituting the display area AA, and n sub-pixels SP may form one pixel. In each of the plurality of sub-pixels SP, a light-emitting diode and a transistor for driving the light-emitting diode are provided, but in the shared sub-pixel SP', a transistor for driving the light-emitting diode LED provided in the shared sub-pixel SP' may not be provided. The plurality of light-emitting diodes may be defined in different ways depending on the type of the display panel PN. For example, when the display panel PN is an inorganic light-emitting display panel, the light-emitting diode may be a light-emitting diode (LED) or a micro light-emitting diode (LED).

[0054] In the display area AA, a plurality of wirings for transmitting various signals to the plurality of sub-pixels SP are provided. For example, the plurality of wirings may include a plurality of data lines DL for supplying a data voltage to each of the plurality of sub-pixels SP, a plurality of scan lines SL for supplying a scan signal to each of the plurality of sub-pixels SP, and the like. The plurality of scan lines SL extend in one direction in the display area AA to be connected to the plurality of sub-pixels SP, and the plurality of data lines DL extend in a direction different from the one direction in the display area AA to be connected to the plurality of sub-pixels SP. In addition, in the display area AA, a low potential power line, a high potential power line, and the like may be further provided, but are not limited thereto.

[0055] The non-display area NA is an area where no image is displayed, so that the non-display area NA may be defined as an area extending from the display area AA. In the non-display area NA, connection lines for transmitting signals to the sub-pixels SP of the display area AA, pad electrodes, driver ICs such as gate driver ICs or data driver ICs, etc. may be provided.

[0056] Meanwhile, the non-display area NA may be located on the rear surface of the display panel PN, that is, on a surface on which the sub-pixels SP are not disposed, or may be omitted and limited to what is shown in the drawings.

[0057] Meanwhile, the drivers (e.g., the gate driver GD, the data driver DD, and the timing controller TC) may be connected to the display panel PN in various ways. For example, the gate driver GD may be installed in the non-display area NA in a gate-in-panel (GIP) manner, or may be installed between a plurality of sub-pixels SP in the display area AA in a gate-in-display area (GIA) manner. For example, the data driver DD and the timing controller TC are formed in a separate flexible film and printed circuit board PCB. The data driver DD and the timing controller TC may be electrically connected to the display panel PN by bonding the flexible film and the printed circuit board PCB to pad electrodes formed in the non-display area NA of the display panel PN.

[0058] If the gate driver GD is installed in a GIP manner and the data driver DD and the timing controller TC transmit signals to the display panel PN through the pad electrode of the non-display area NA, the area of ​​the non-display area NA for setting the gate driver GD and the pad electrode needs to be larger than a predetermined level. Therefore, the frame may increase.

[0059] On the contrary, when the gate driver GD is installed in the display area AA in a GIA manner and a side line connecting a signal line on the front surface of the display panel PN to a pad electrode on the back surface of the display panel PN is formed to bond a flexible film and a printed circuit board to the back surface of the display panel PN, the non-display area NA can be minimized on the front surface of the display panel PN. That is, when the gate driver GD, the data driver DD, and the timing controller TC are connected to the display panel PN as described above, a zero frame having substantially no frame can be realized.

[0060] Figure 2A is a plan view of a pixel region of a display device according to an exemplary embodiment of the present disclosure, Figure 2B is a cross-sectional view of a pixel region of a display device according to an exemplary embodiment of the present disclosure. Figure 2A and Figure 2B In FIG. 1 , it is shown that all the light emitting diodes disposed in the first sub-pixel SP1, the second sub-pixel SP2, and the shared sub-pixel SP′ are normal, and the light emitting diodes are transferred normally. Figure 2A In the figure, for the convenience of description, among the components of the display device 100, only the light emitting diode LED, the common power line VL, the connection pattern CP and the dummy pattern DP are illustrated.

[0061] Reference Figure 2A, the plurality of sub-pixels SP may include a first sub-pixel SP1, a second sub-pixel SP2, and a shared sub-pixel SP'. The first sub-pixel SP1 and the second sub-pixel SP2 are sub-pixels that are generally used, and the shared sub-pixel SP' is a sub-pixel that is used when any one of the first sub-pixel SP1 and the second sub-pixel SP2 is defective. For example, when the light emitting diode LED provided in any one of the first sub-pixel SP1 and the second sub-pixel SP2 itself is defective, or the light emitting diode LED is not transferred, or the light emitting diode LED is transferred incorrectly and deviates from the normal position, the shared sub-pixel SP' may be used to replace the corresponding sub-pixel. Below, as described above, an example will be described in which the shared light emitting diode LED' of the first sub-pixel SP1, the second sub-pixel SP2, and the shared sub-pixel SP' is normal and is transferred normally.

[0062] Reference Figure 2A and Figure 2B The substrate 110 is a substrate that supports components disposed above the display device 100 and may be an insulating substrate. For example, the substrate 110 may be formed of glass or resin. In addition, the substrate 110 may include a polymer or plastic. In some exemplary embodiments, the substrate 110 may be formed of a plastic material having flexibility. A plurality of pixels are formed on the substrate 110 to display an image.

Figure 2B In the embodiment, for the convenience of description, only the driving transistor DT and the storage capacitor Cst in the configuration of the pixel circuit are illustrated. However, the pixel circuit may further include a switching transistor, a sensing transistor, a light emission control transistor, etc., but is not limited thereto.

[0065] First, a light shielding layer BSM is provided on the substrate 110. The light shielding layer BSM blocks light incident on the active layer ACT of a plurality of transistors to minimize leakage current. For example, the light shielding layer BSM is provided below the active layer ACT of the driving transistor DT to block light incident on the active layer ACT. If light is irradiated onto the active layer ACT, leakage current is generated, which deteriorates the reliability of the transistor. Therefore, a light shielding layer BSM that blocks light is provided on the substrate 110 to improve the reliability of the driving transistor DT. The light shielding layer BSM may be formed of an opaque conductive material such as copper (Cu), aluminum (Al), molybdenum (Mo), nickel (Ni), titanium (Ti), chromium (Cr), or an alloy of the foregoing metals, but is not limited thereto.

The buffer layer 111 can be made of silicon oxide (SiO x ) or silicon nitride (SiN x ) is composed of a single layer or a double layer, but is not limited thereto. However, the buffer layer 111 may be omitted according to the type of the substrate 110 or the type of the transistor, but is not limited thereto.

[0067] A driving transistor DT including an active layer ACT, a gate electrode GE, a source electrode SE, and a drain electrode DE is disposed on the buffer layer 111 .

[0068] Although Figure 2B Not shown in the figure, another buffer layer may be disposed between the substrate 110 and the light shielding layer BSM.

[0069] First, the active layer ACT of the driving transistor DT is arranged on the buffer layer 111.

The active layers of the transistors included in the pixel circuit (for example, the driving transistor DT, the switching transistor, the sensing transistor and the light-emitting control transistor) may be formed of the same material, or of different materials.

[0070] The gate insulating layer 112 is disposed on the active layer ACT. The gate insulating layer 112 is an insulating layer that electrically insulates the active layer ACT from the gate GE, and may be made of silicon oxide (SiO x ) or silicon nitride (SiN x ) of single layer or double layer, but not limited to this.

[0071] The gate GE is disposed on the gate insulating layer 112. The gate GE may be made of a conductive material, such as copper (Cu), aluminum (Al), molybdenum (Mo), nickel (Ni), titanium (Ti), chromium (Cr), or an alloy thereof, but is not limited thereto.

Contact holes are formed in the first interlayer insulating layer 113 and the second interlayer insulating layer 114, and each of the source electrode SE and the drain electrode DE is connected to the active layer ACT through the contact holes. The first interlayer insulating layer 113 and the second interlayer insulating layer 114 are insulating layers that protect the elements thereunder and may be made of silicon oxide (SiO x ) or silicon nitride (SiN x ) of single layer or double layer, but not limited to this.

[0074] The storage capacitor Cst may be disposed on the gate insulating film 112. The storage capacitor Cst may be configured with a metal layer TM and a gate GE as a capacitor electrode, but is not limited thereto and may be implemented in various ways.

[0075] The metal layer TM may be disposed on the first interlayer insulating layer 113. The metal layer TM may be disposed to overlap with the gate GE (the first interlayer insulating layer 113 is located between the metal layer TM and the gate GE).

[0076] The source electrode SE and the drain electrode DE electrically connected to the active layer ACT are disposed on the second interlayer insulating layer 114. The drain electrode DE is electrically connected to the storage capacitor Cst and the second electrode 135 of the light emitting diode LED and the source electrode SE is connected to another structure of the pixel circuit. The source electrode SE and the drain electrode DE may be made of a conductive material such as copper (Cu), aluminum (Al), molybdenum (Mo), nickel (Ni), titanium (Ti), chromium (Cr), or an alloy of the foregoing metals, but are not limited thereto.

[0077] The first planarization layer 115 is disposed on the source electrode SE and the drain electrode DE. The first planarization layer 115 may planarize the upper portion of the pixel circuit including the driving transistor DT. The first planarization layer 115 may be composed of a single layer or a double layer, and may be composed of, for example, benzocyclobutene or an acrylic organic material, but is not limited thereto.

[0078] A plurality of reflection plates RF may be disposed on the first planarization layer 115. Specifically, the plurality of reflection plates RF are disposed under the plurality of light emitting diodes LED to be electrically connected to the light emitting diodes, respectively.

[0079] The reflector RF is a configuration that reflects light emitted from a plurality of light emitting diodes LED above the substrate 110, and may be formed with a shape corresponding to each of a plurality of sub-pixels SP. The reflector RF may reflect light emitted from the light emitting diodes LED and may also be used as an electrode that electrically connects the light emitting diodes LED and the pixel circuit. That is, the reflector RF may electrically connect the first electrode 134 and the common power line VL. Therefore, in consideration of light reflection efficiency and resistance, the reflector RF may include various conductive layers. For example, the reflector RF may use an opaque conductive layer such as silver (Ag), aluminum (Al), molybdenum (Mo), titanium (Ti), or an alloy of the foregoing metals and a transparent conductive layer such as indium tin oxide ITO, but the combination of the reflector RF is not limited thereto.

[0080] The intermediate electrode CE may be disposed on the first planarization layer 115. The intermediate electrode CE may be connected to the plurality of connection patterns CP and the drain electrode DE of the driving transistor DT through the contact hole. That is, the intermediate electrode CE may electrically connect the driving transistor DT and the first light emitting diode LED1 disposed in the first sub-pixel SP1 or electrically connect the driving transistor DT and the second light emitting diode LED2 disposed in the second sub-pixel SP2. At this time, the intermediate electrode CE may be formed of the same material as the plurality of reflection plates RF, but is not limited thereto.

[0082] The first light emitting diode LED1 may be disposed in the first sub-pixel SP1, the second light emitting diode LED2 may be disposed in the second sub-pixel SP2, and the common light emitting diode LED' may be disposed in the common sub-pixel SP'. At this time, the first light emitting diode LED1, the second light emitting diode LED2, and the common light emitting diode LED' may emit light having the same color. That is, all of the first light emitting diode LED1, the second light emitting diode LED2, and the common light emitting diode LED' may be a red light emitting diode, a green light emitting diode, or a blue light emitting diode. At this time, each of the first light emitting diode LED1 and the second light emitting diode LED2 is connected to the transistor of each of the first sub-pixel SP1 and the second sub-pixel SP2 to be driven individually. On the contrary, the common light emitting diode LED' of the common sub-pixel SP' may be used as an auxiliary light emitting diode of the first light emitting diode LED1 and the second light emitting diode LED2. Therefore, the common light emitting diode LED' may be driven by the transistor of the first sub-pixel SP1 or the second sub-pixel SP2 through the connection pattern CP. However, in the display device 100 according to the exemplary embodiment of the present disclosure, both the first light emitting diode LED1 and the second light emitting diode LED2 are normal and are normally transferred, so that the common light emitting diode LED' may not be used.

In this case, the first semiconductor layer 131 is a semiconductor layer doped with p-type impurities and the first electrode 134 may be an anode. The first electrode 134 may be composed of a conductive material, for example, a transparent conductive material such as indium tin oxide (ITO) or indium zinc oxide (IZO), or an opaque conductive material such as titanium (Ti), gold (Au), silver (Ag), copper (Cu), or an alloy of the foregoing metals, but is not limited thereto.

[0089] The passivation film 136 is disposed on the sidewalls of the first semiconductor layer 131, the light emitting layer 132, the second semiconductor layer 133, the first electrode 134, and the second electrode 135. The passivation film 136 surrounds the first semiconductor layer 131, the light emitting layer 132, the second semiconductor layer 133, the first electrode 134, and the second electrode 135. The passivation film 136 is a film for protecting the first semiconductor layer 131, the light emitting layer 132, the second semiconductor layer 133, the first electrode 134, and the second electrode 135. For example, the passivation film 136 may be made of a transparent epoxy resin, silicon oxide (SiO x ) or silicon nitride (SiN x ), but not limited to this.

[0090] Next, the second planarization layer 121 and the third planarization layer 122 are disposed to surround the light emitting diode LED.

[0091] The second planarization layer 121 overlaps a portion of the side surfaces of the plurality of light emitting diodes LED to fix and protect the plurality of light emitting diodes LED. For example, the second planarization layer 121 may be made of benzocyclobutene or acrylic organic material, but is not limited thereto.

[0092] The third planarization layer 122 may be formed to cover an upper portion of the second planarization layer 121 and a portion of a side surface of the light emitting diode LED. For example, the third planarization layer 122 may be made of benzocyclobutene or an acrylic organic material, but is not limited thereto.

[0093] The connection pattern CP and the common power line VL are disposed on the third planarization layer 122. The common power line VL may be electrically connected to the reflective plate RF disposed under the light emitting diode LED through contact holes formed in the second planarization layer 121 and the third planarization layer 122. That is, the common power line VL is disposed at one side of the first sub-pixel SP1, the second sub-pixel SP2, and the shared sub-pixel SP' to apply a common power supply to the first sub-pixel SP1, the second sub-pixel SP2, and the shared sub-pixel SP'. For example, the common power line VL may be a high potential power line that transmits a high potential power supply voltage, but is not limited thereto.

[0094] The connection pattern CP may electrically connect the second electrode 135 of the light emitting diode LED and the driving transistor DT through the contact holes formed in the second planarization layer 121 and the third planarization layer 122. That is, in the display device 100 according to the exemplary embodiment of the present disclosure, the first light emitting diode LED1 and the second light emitting diode LED2 operate normally. Therefore, in order to drive the first light emitting diode and the second light emitting diode separately, the first connection pattern CP1 and the second connection pattern CP2 of the connection pattern CP may be arranged to be spaced apart from each other. That is, the first connection pattern CP1 arranged at the other side of the first sub-pixel SP1 may connect the driving transistor DT arranged in the first sub-pixel SP1 and the first light emitting diode LED1. The second connection pattern CP2 arranged at the other side of the second sub-pixel SP2 may connect the driving transistor DT and the second light emitting diode LED2 arranged in the second sub-pixel SP2.

[0095] The dummy pattern DP connected to the shared light emitting diode LED' may be arranged on the same layer as the connection pattern CP. Therefore, the dummy pattern DP may be formed of the same material as the plurality of connection patterns CP. When the first sub-pixel SP1 and the second sub-pixel SP2 are normal, the shared light emitting diode LED' arranged in the shared sub-pixel SP' does not need to be driven. Therefore, the shared light emitting diode LED' does not need to be connected to the driving transistor DT arranged in the first sub-pixel SP1 or the second sub-pixel SP2, and the dummy pattern DP may be arranged to be spaced apart from the first connection pattern CP1 and the second connection pattern CP2. Therefore, the dummy pattern DP may be arranged to float.

[0096] Generally, among the multiple sub-pixels arranged on the substrate, defective sub-pixels that do not emit light normally may be generated. For example, when the light-emitting diode itself is defective or the light-emitting diode is not transferred normally, the corresponding sub-pixel may become a defective sub-pixel. Therefore, in order to prepare for the occurrence of defective sub-pixels, additional sub-pixels that emit the same light as each of the multiple sub-pixels are set. For example, when the multiple sub-pixels are composed of red sub-pixels, green sub-pixels, and blue sub-pixels, two red sub-pixels that emit light based on the same data signal, two green sub-pixels that emit light based on the same data signal, and two blue sub-pixels that emit light based on the same data signal are arranged on the substrate. Therefore, even if one red sub-pixel is a defective sub-pixel, the other red sub-pixel emits light to suppress the defects of the entire display device. However, when the display device is configured as described above, in order to ensure the placement space of the additional sub-pixels, a separate additional area is required, making it difficult to realize a high-resolution display device. In addition, since the number of light-emitting diodes to be transferred to the display device is doubled, the manufacturing cost of the display device is also significantly increased.

[0097] Therefore, during the initial manufacturing process of the display device, the light-emitting diodes are not transferred twice in advance, but only an area for performing a repair process later is left to manufacture the display device. That is, when a sub-pixel is a defective sub-pixel, a light-emitting diode that emits light of the same color as the color emitted by the sub-pixel is transferred to the area where the repair process is performed using a repair process. In this case, the light-emitting diodes are not initially transferred twice, so that the manufacturing cost of the display device will be lower than the above case. However, there may be limitations on the type of light-emitting diodes used for the repair process. In addition, flip-chip type light-emitting diodes are generally used to perform the repair process. When the light-emitting diodes initially transferred are vertical or lateral, the different types of light-emitting diodes may cause different light-emitting characteristics. In addition, there is a disadvantage that flip-chip type light-emitting diodes are difficult to reduce the size of the light-emitting diodes in terms of electrode connection or transfer.

[0098] Therefore, in the display device 100 according to the exemplary embodiment of the present disclosure, the first sub-pixel SP1 and the second sub-pixel SP2 that emit light of the same color and are adjacent to each other can share the common sub-pixel SP' disposed between the first sub-pixel SP1 and the second sub-pixel SP2 as an auxiliary sub-pixel. Therefore, in the display device 100 according to the exemplary embodiment of the present disclosure, 1.5 times the minimum number of light-emitting diodes LED required to display an image needs to be transferred. Therefore, the manufacturing yield of the display device 100 can be improved and the manufacturing cost of the display device 100 can be reduced.

[0099] In addition, in the display device 100 according to the exemplary embodiment of the present disclosure, the first sub-pixel SP1 and the second sub-pixel SP2 are not limited to having separate auxiliary sub-pixels but share a common sub-pixel SP', so that the design area can be ensured. For example, when all the individual sub-pixels have auxiliary sub-pixels, a total of six sub-pixels can be defined as one pixel. However, in the display device 100 according to the exemplary embodiment of the present disclosure, the first sub-pixel SP1 and the second sub-pixel SP2 share a common sub-pixel SP' so that a total of 4.5 sub-pixels SP can be defined as one pixel. Therefore, the area occupied by one pixel is reduced, so that the number of sub-pixels SP included in the display device 100 can be increased, so that a high-resolution display device can be realized.

[0100] Hereinafter, a display device according to various exemplary embodiments of the present disclosure will be described in which a defective light emitting diode is disposed in a first sub-pixel or a second sub-pixel or a light emitting diode is incorrectly transferred.

[0101] Figure 3A is a plan view of a pixel region of a display device according to another exemplary embodiment of the present disclosure. Figure 3B is along Figure 3A A cross-sectional view taken along line IIIb-IIIb'. Figure 3A and Figure 3B , it is illustrated that the light emitting diodes disposed in the first sub-pixel SP1, the second sub-pixel SP2, and the shared sub-pixel SP' are normally transferred, but only the first light emitting diode LED1 is defective. Figure 3A In the figure, for the convenience of description, among the various components of the display device 300, only the light emitting diode LED, the common power line VL and the connection pattern CP are illustrated. Figure 3A and Figure 3B In the display device 300, Figures 1 to 2B The display device 100 of FIG. 1 is different only in whether the first light emitting diode LED1 is defective, the presence of the dummy pattern DP, and the connection pattern DP, and other components are substantially the same. Therefore, repeated description will be omitted.

[0102] Reference Figure 3A and Figure 3B , the connection pattern CP is disposed on the third planarization layer 122. The connection pattern CP may electrically connect the second electrode 135 of the light emitting diode LED and the driving transistor DT through the contact hole formed in the second planarization layer 121 and the third planarization layer 122. In the display device 300 according to another exemplary embodiment of the present disclosure, the first light emitting diode LED1 is defective, so that the first sub-pixel SP1 does not emit light. Therefore, the shared light emitting diode LED' disposed in the shared sub-pixel SP' may be driven to replace the first light emitting diode LED1 disposed in the first sub-pixel SP1. Specifically, the first connection pattern CP1 may electrically connect the driving transistor DT and the shared light emitting diode LED' disposed in the first sub-pixel SP1. Therefore, the shared light emitting diode LED' may be electrically connected to the driving transistor DT through the first connection pattern CP1 and the intermediate electrode CE. In addition, the second connection pattern CP2 may electrically connect the driving transistor DT and the second light emitting diode LED2 disposed in the second sub-pixel SP2. Therefore, the first connection pattern CP1 and the second connection pattern CP2 may be disposed to be spaced apart from each other.

[0103] In a display device 300 according to another exemplary embodiment of the present disclosure, a first sub-pixel SP1 and a second sub-pixel SP2 that emit light of the same color and are adjacent to each other may share a common sub-pixel SP' disposed between the first sub-pixel SP1 and the second sub-pixel SP2 as an auxiliary sub-pixel. Therefore, the manufacturing yield of the display device 300 may be improved and the manufacturing cost of the display device 300 may be reduced.

[0104] In addition, in the display device 300 according to another exemplary embodiment of the present disclosure, the first sub-pixel SP1 and the second sub-pixel SP2 are not limited to have separate auxiliary sub-pixels but share a common sub-pixel SP', so that the design area can be ensured. Therefore, the area occupied by one pixel is reduced, so that the number of sub-pixels SP included in the display device 300 can be increased, so that a high-resolution display device can be realized.

[0105] In a display device 300 according to another exemplary embodiment of the present disclosure, when the first light emitting diode LED1 provided in the first sub-pixel SP1 is defective, the shared light emitting diode LED' provided in the shared sub-pixel SP' is driven to emit light instead of the defective sub-pixel. Specifically, the first connection pattern CP1 can electrically connect the driving transistor DT provided in the first sub-pixel SP1 with the shared light emitting diode LED' to drive the shared light emitting diode LED' provided in the shared sub-pixel SP'. That is, the shared sub-pixel SP' can be driven as an auxiliary sub-pixel of the first sub-pixel SP1 through the first connection pattern CP1 without a separate pixel circuit in the shared sub-pixel SP' provided with the shared light emitting diode LED'. Therefore, in a display device 300 according to another exemplary embodiment of the present disclosure, the shared sub-pixel SP' as an auxiliary sub-pixel can be driven without separate position programming to make the shared sub-pixel SP' emit light. In addition, in a display device 300 according to another exemplary embodiment of the present disclosure, each sub-pixel SP only turns on one light emitting diode LED to make the shared sub-pixel SP' serve as an auxiliary sub-pixel to repair the defective pixel without brightness compensation between the sub-pixels SP.

Figure 4A and Figure 4B , it is illustrated that the light emitting diodes LED disposed in the first sub-pixel SP1, the second sub-pixel SP2, and the shared sub-pixel SP' are normally transferred, but only the second light emitting diode LED2 is defective. Figure 4A In the figure, for the convenience of description, among the various components of the display device 400, only the light emitting diode LED, the common power line VL and the connection pattern CP are illustrated.

Therefore, repeated description will be omitted.

The connection pattern CP may electrically connect the second electrode 135 of the light emitting diode LED with the driving transistor DT through the contact hole formed in the second planarization layer 121 and the third planarization layer 122. In the display device 400 according to another exemplary embodiment of the present disclosure, the second light emitting diode LED2 is defective, so that the second sub-pixel SP2 does not emit light. Therefore, the shared light emitting diode LED' disposed in the shared sub-pixel SP' may be driven to replace the second light emitting diode LED2 disposed in the second sub-pixel SP2. Specifically, the second connection pattern CP2 may electrically connect the driving transistor DT disposed in the second sub-pixel SP2 with the shared light emitting diode LED'. Therefore, the shared light emitting diode LED' may be electrically connected to the driving transistor DT through the second connection pattern CP2 and the intermediate electrode CE. In addition, the first connection pattern CP1 may electrically connect the driving transistor DT disposed in the first sub-pixel SP 1 with the first light emitting diode LED 1. Therefore, the first connection pattern CP1 and the second connection pattern CP2 may be disposed to be spaced apart from each other.

[0108] In a display device 400 according to another exemplary embodiment of the present disclosure, a first sub-pixel SP1 and a second sub-pixel SP2 that emit light of the same color and are adjacent to each other may share a common sub-pixel SP' disposed between the first sub-pixel SP1 and the second sub-pixel SP2 as an auxiliary sub-pixel. Therefore, the manufacturing yield of the display device 400 may be improved and the manufacturing cost of the display device 400 may be reduced.

[0109] In addition, in the display device 400 according to another exemplary embodiment of the present disclosure, the first sub-pixel SP1 and the second sub-pixel SP2 are not limited to having separate auxiliary sub-pixels but share a common sub-pixel SP', so that the design area can be ensured.

Specifically, the second connection pattern CP2 can electrically connect the driving transistor DT disposed in the second sub-pixel SP2 with the shared light emitting diode LED' to drive the shared light emitting diode LED' disposed in the shared sub-pixel SP'. That is, the shared sub-pixel SP' can be driven as an auxiliary sub-pixel of the second sub-pixel SP2 through the second connection pattern CP2 without requiring a separate pixel circuit in the shared sub-pixel SP' where the shared light emitting diode LED' is disposed. Therefore, in a display device 400 according to another exemplary embodiment of the present disclosure, the shared sub-pixel SP' as an auxiliary sub-pixel can be driven without separate position programming to make the shared sub-pixel SP' emit light. In addition, in a display device 400 according to another exemplary embodiment of the present disclosure, each sub-pixel SP only turns on one light emitting diode LED to make the shared sub-pixel SP' serve as an auxiliary sub-pixel to repair the defective pixel without performing brightness compensation between the sub-pixels SP.

[0111] Figure 5A is a plan view of a pixel region of a display device according to still another exemplary embodiment of the present disclosure. Figure 5B is along Figure 5A A cross-sectional view taken along the line Vb-Vb'. Figure 5A and Figure 5B In FIG. 1 , it is illustrated that all the light emitting diodes disposed in the second sub-pixel SP2 and the shared sub-pixel SP′ are normal and the light emitting diodes are also transferred normally, but the first light emitting diode LED1 is mistakenly transferred to the first sub-pixel SP1 and deviates from the normal position.

Therefore, repeated description will be omitted.

[0112] Reference Figure 5A and Figure 5B, the first light emitting diode LED1 is mistakenly transferred, so that the first light emitting diode LED1 is not connected to the first connection pattern CP1. Therefore, the first light emitting diode LED1 may not be connected to the driving transistor DT provided in the first sub-pixel SP1 and may not emit light. Therefore, in the display device 500 according to another exemplary embodiment of the present disclosure, the shared sub-pixel SP' may emit light instead of the first sub-pixel. At the same time, Figure 5A and Figure 5B However, even if the first light emitting diode LED1 is connected to the first connection pattern CP1, when sufficient connection for driving the first light emitting diode LED1 is not provided, the shared subpixel SP' may emit light instead of the first subpixel.

Figure 7B is along Fig. 7A A cross-sectional view taken along line VIIb-VIIb'. Fig. 7A and Figure 7B In FIG. 1 , it is illustrated that all the light emitting diodes disposed in the second sub-pixel SP2 and the shared sub-pixel SP′ are normal and the light emitting diodes are also transferred normally, but the first light emitting diode LED1 is not transferred to the first sub-pixel SP1.

Therefore, repeated description will be omitted.

[0124] Reference Fig. 7A and Figure 7B , the first light emitting diode LED1 is not transferred, so that the light emitting diode is not disposed on the reflection plate RF of the first sub-pixel SP1. Therefore, the second planarization layer 121 and the third planarization layer 122 are disposed on the reflection plate of the first sub-pixel 11. Therefore, the first sub-pixel SP1 may not emit light. Therefore, in the display device 700 according to another exemplary embodiment of the present disclosure, the shared sub-pixel SP' may emit light instead of the first sub-pixel SP1.

[0125] Reference Fig. 7A and Figure 7B , the connection pattern CP is disposed on the third planarization layer 122. The connection pattern CP may electrically connect the second electrode 135 of the light emitting diode LED with the driving transistor DT through the contact holes formed in the second planarization layer 121 and the third planarization layer 122. In the display device 700 according to another exemplary embodiment of the present disclosure, the first light emitting diode LED1 is not transferred, so that the first sub-pixel SP1 does not emit light. Therefore, the shared light emitting diode LED' disposed in the shared sub-pixel SP' may be driven to replace the first light emitting diode LED1. Specifically, the first connection pattern CP1 may electrically connect the driving transistor DT disposed in the first sub-pixel SP1 with the shared light emitting diode LED'.

[0127] In addition, in the display device 700 according to another exemplary embodiment of the present disclosure, the first sub-pixel SP1 and the second sub-pixel SP2 are not limited to having separate auxiliary sub-pixels but share a common sub-pixel SP', so that the design area can be ensured. Therefore, the area occupied by one pixel is reduced, so that the number of sub-pixels SP included in the display device 700 can be increased, so that a high-resolution display device can be realized.

[0128] In a display device 700 according to another exemplary embodiment of the present disclosure, when the first light emitting diode LED1 is not transferred to the first sub-pixel SP1, the shared light emitting diode LED' disposed in the shared sub-pixel SP' is driven as a substitute to repair the defective sub-pixel. Specifically, the first connection pattern CP1 can electrically connect the driving transistor DT disposed in the first sub-pixel SP1 with the shared light emitting diode LED' to drive the shared light emitting diode LED' disposed in the shared sub-pixel SP'. That is, the shared sub-pixel SP' can be driven as an auxiliary sub-pixel of the first sub-pixel SP1 through the first connection pattern CP1 without a separate pixel circuit in the shared sub-pixel SP' where the shared light emitting diode LED' is disposed. Therefore, in a display device 700 according to another exemplary embodiment of the present disclosure, the shared sub-pixel SP' as an auxiliary sub-pixel can be driven without separate position programming to make the shared sub-pixel SP' emit light. In addition, in a display device 700 according to another exemplary embodiment of the present disclosure, each sub-pixel SP only turns on one light emitting diode LED to make the shared sub-pixel SP' serve as an auxiliary sub-pixel to repair the defective pixel without brightness compensation between the sub-pixels SP.

[0129] Fig. 8A is a plan view of a pixel region of a display device according to still another exemplary embodiment of the present disclosure. Figure 8B is along Fig. 8A A cross-sectional view taken along line VIIIb-VIIIb'. Fig. 8A and Figure 8B In FIG. 1 , it is illustrated that all the light emitting diodes disposed in the first sub-pixel SP1 and the shared sub-pixel SP′ are normal and the light emitting diodes are also transferred normally, but the second light emitting diode LED2 is not transferred to the second sub-pixel SP2. Fig. 8A In the figure, for the convenience of description, among the various components of the display device 800, only the light emitting diode LED, the common power line VL and the connection pattern CP are illustrated. Fig. 8A and Figure 8B In the display device 800, Figures 1 to 2BThe display device 100 of FIG. 1 is different only in whether the second light emitting diode LED2 is not transferred, the presence of the dummy pattern DP, and the connection pattern DP, and other components are substantially the same. Therefore, repeated description will be omitted.

[0130] refer to Fig. 8A and 8B , the second light emitting diode LED2 is not transferred, so that the light emitting diode LED is not disposed on the reflection plate RF of the second sub-pixel SP2. Therefore, the second planarization layer 121 and the third planarization layer 122 are disposed on the reflection plate RF of the second sub-pixel SP2. Therefore, the second sub-pixel SP2 may not emit light. Therefore, in the display device 800 according to another exemplary embodiment of the present disclosure, the shared sub-pixel SP' may emit light instead of the second sub-pixel SP2.

[0131] Reference Fig. 8A and Figure 8B , the connection pattern CP is disposed on the third planarization layer 122. The connection pattern CP may electrically connect the second electrode 135 of the light emitting diode LED with the driving transistor DT through the contact hole formed in the second planarization layer 121 and the third planarization layer 122. In the display device 800 according to another exemplary embodiment of the present disclosure, the second light emitting diode LED2 is not transferred, so that the second sub-pixel SP2 does not emit light. Therefore, the shared light emitting diode LED' disposed in the shared sub-pixel SP' may be driven instead of the second light emitting diode LED2. Specifically, the second connection pattern CP2 may electrically connect the driving transistor DT disposed in the second sub-pixel SP2 with the shared light emitting diode LED'. Therefore, the shared light emitting diode LED' may be electrically connected to the driving transistor DT through the second connection pattern CP2 and the intermediate electrode CE. In addition, the first connection pattern CP1 may electrically connect the driving transistor DT disposed in the first sub-pixel SP1 with the first light emitting diode LED1. Therefore, the first connection pattern CP1 and the second connection pattern CP2 may be disposed to be spaced apart from each other.

[0132] In a display device 800 according to another exemplary embodiment of the present disclosure, a first sub-pixel SP1 and a second sub-pixel SP2 that emit light of the same color and are adjacent to each other may share a common sub-pixel SP' disposed between the first sub-pixel SP1 and the second sub-pixel SP2 as an auxiliary sub-pixel. Therefore, the manufacturing yield of the display device 800 may be improved and the manufacturing cost of the display device 800 may be reduced.

[0133] In addition, in the display device 800 according to another exemplary embodiment of the present disclosure, the first sub-pixel SP1 and the second sub-pixel SP2 are not limited to having separate auxiliary sub-pixels but share a common sub-pixel SP', so that the design area can be ensured. Therefore, the area occupied by one pixel is reduced, so that the number of sub-pixels SP included in the display device 800 can be increased, so that a high-resolution display device can be realized.

[0134] In a display device 800 according to another exemplary embodiment of the present disclosure, when the second light emitting diode LED2 disposed in the second sub-pixel SP2 is not transferred, the shared light emitting diode LED' disposed in the shared sub-pixel SP' is driven as a substitute to repair the defective sub-pixel. Specifically, the second connection pattern CP2 can electrically connect the driving transistor DT disposed in the second sub-pixel SP2 with the shared light emitting diode LED' to drive the shared light emitting diode LED' disposed in the shared sub-pixel SP'. That is, the shared sub-pixel SP' can be driven as an auxiliary sub-pixel of the second sub-pixel SP2 through the second connection pattern CP2 without a separate pixel circuit in the shared sub-pixel SP' where the shared light emitting diode LED' is disposed. Therefore, in a display device 800 according to another exemplary embodiment of the present disclosure, the shared sub-pixel SP' as an auxiliary sub-pixel can be driven without separate position programming to make the shared sub-pixel SP' emit light. In addition, in a display device 800 according to another exemplary embodiment of the present disclosure, each sub-pixel SP only turns on one light emitting diode LED to make the shared sub-pixel SP' serve as an auxiliary sub-pixel to repair the defective pixel without the need for brightness compensation between the sub-pixels SP.

[0135] In the following, reference will be made to 9A to 9C A method of manufacturing the display device 800 according to an exemplary embodiment of the present disclosure is described in detail.

[0136] 9A to 9C 1 is a schematic process diagram for explaining a method for manufacturing a display device according to an exemplary embodiment of the present invention. Fig. 8A and Figure 8B ,exist 9A to 9C In FIG. 1 , it is shown that all the light emitting diodes disposed in the first sub-pixel SP1 and the shared sub-pixel SP′ are normal and the light emitting diodes are also normally transferred, but the second light emitting diode LED2 is not transferred to the second sub-pixel SP2. Fig. 9A In the figure, among the various components of the display device 800, only the light emitting diode LED is shown, and Fig. 9B and Fig. 9C In FIG. 1 , only the light emitting diode LED, the common power line VL, the connection pattern CP and the temporary pattern TP are illustrated. 9A to 9CIn the example, only the temporary pattern TP is added to Fig. 8A and Figure 8B , and the other components are substantially the same. Therefore, repeated description will be omitted.

[0137] First, refer to Fig. 9A and Fig. 9B , after transferring the plurality of light emitting diodes LED to the plurality of sub-pixels SP, the common power line VL may be disposed on one side and the temporary pattern TP may be disposed on the other side.

[0138] The temporary pattern TP is disposed on the other side of the first sub-pixel SP1, the second sub-pixel SP2, and the shared sub-pixel SP' to simultaneously turn on the first sub-pixel SP1, the second sub-pixel SP2, and the shared sub-pixel SP', thereby detecting a defective sub-pixel SP. For example, when a lighting test is performed by supplying power to the common power line VL and the temporary pattern TP, if the light emitting diode LED is normal and is normally transferred, the light emitting diode LED may emit light. As described above, the second light emitting diode LED2 is not transferred to the second sub-pixel SP2 so that the second sub-pixel may not emit light.

[0139] Although Fig. 9A and Fig. 9B , the second light emitting diode LED2 is not transferred to the second sub-pixel SP2, but is not limited thereto. Therefore, when any one of the first light emitting diode LED1 and the second light emitting diode LED2 is defective, or any one is transferred incorrectly, or any one is not transferred, the present disclosure can be applied in the same manner.

[0140] Reference Fig. 9C , the second sub-pixel SP2 is defective, so that the shared sub-pixel SP' can be driven as an auxiliary sub-pixel of the second sub-pixel SP2. Therefore, the temporary pattern TP can be patterned into a first connection pattern CP1 and a second connection pattern CP2, so that the normal first sub-pixel SP1 and the shared sub-pixel SP' are driven separately. Specifically, the temporary pattern TP can be patterned into a first connection pattern CP1 and a second connection pattern CP2. Therefore, the first sub-pixel SP1 can be driven by a driving transistor DT set in the first sub-pixel SP1 through the first connection pattern CP1, and the shared sub-pixel SP' can be driven by a driving transistor DT set in the second sub-pixel SP2 through the second connection pattern CP2. At this time, the temporary pattern TP, which is usually set in a plurality of sub-pixels SP, is patterned into a first connection pattern CP1 and a second connection pattern CP2, so that the length of the plurality of connection patterns CP can be longer than the width of one sub-pixel SP.
