In this way, the lifetime of the organic light emitting element of the sub-pixel can be improved.In one embodiment, the second reset control sub-signal can be the sameas the scan signal. That is, the gate electrode of the second reset transistorT7 can be electrically connected to the scan signal line Ga1 to receive the scan signal as the second reset control sub-signal.In one embodiment, the gate electrode of the first reset transistor T6 and the source electrode of the second reset transistor T7 are connected to the first reset power supply terminal Vinit1 and the second reset powersupply terminal Vinit2, respectively, and the first reset power supply terminal Vinit1 and the second reset power supply terminal Vinit2 can be aDC reference voltage terminal to output a constant DC reference voltage.The first reset power supply terminal Vinit1 and the second reset powersupply terminal Vinit2 can be the same signal, for example, the gate electrode of the first reset transistor T6 and the source electrode of the second reset transistor T7 are connected to the same reset power supplyterminal. The first reset power supply terminal Vinit1 and the second resetpower supply terminal Vinit2 can be high voltage terminals or low voltageterminals, as long as they can provide the first reset signal and the secondreset signal to the gate electrode of the driving transistor T1 and the firstelectrode of the light emitting element 220 for reset, which is not limited inthis application.It should be noted that the driving circuit 222, the data writing circuit226, the storage circuit 227, the threshold compensation circuit 228 and thereset circuit 229 in the pixel circuit shown in FIG 1 are only for illustration,and the specific structures of the writing circuit 226, the storage circuit 227,the threshold compensation circuit 228, and the reset circuit 229 can be provided according to actual application requirements, which are notspecifically limited in the embodiments of the present application.According to the characteristics of transistors, transistors can bedivided into N-type transistors and P-type transistors.

In the embodiments of the present application, in orderto distinguish the transistors, except for the gate electrodes serving as thecontrol electrodes, one of the source and drain electrodes is simply referred to as the first electrode and the other as the second electrode. Therefore, in the embodiments of the present application, the first and second electrodes of all or some of the transistors are interchangeable as required.It should be noted that, in the embodiment of the present application,the pixel circuit of the sub-pixel can be a 7T1C (that is, seven transistors and one capacitor) structure shown in FIG. 1, and can also include other numbers of transistors, such as a 7T2C structure, a 6T1C structure, a 6T2Cstructure, or a 9T2C structure, which is not limited in this embodiment ofthe present application.FIGS. 2-7 are schematic diagrams of various layers of a pixel circuitaccording to an embodiment of the present application. The followingdescribes the positional relationship of each circuit in the pixel circuit on the backplane with reference to FIGS. 2-7. The example shown in FIG. 2-7takes the pixel circuit 221 of one pixel group as an example, and takes thepositions of the transistors included in the first color sub-pixel 110 forillustration. The positions of the transistors in the pixel circuits of the second color sub-pixel 120 and the third color sub-pixel 130 are substantially thesame as the positions of the transistors included in the first color sub-pixel.As shown in FIG. 2, the pixel circuit 221 of the first color sub-pixel 110includes a driving transistor T1, a data writing transistor T2, a thresholdcompensation transistor T3, a first light emitting control transistor T4, and a second light emitting control transistor T5, a first reset transistor T6, a second reset transistor T7 and a capacitor C, as shown in FIG. 1.FIG. 2-7 also shows a scan signal line Ga1, a reset control signal line Rst1, a reset power supply signal line Init1, a light emitting control signalline EM1, a data line Vd, power supply signal lines (including a first power supply signal line VDD1, a second power supply signal line VDD3 and athird power supply signal line VDD2 of the first power supply terminal VDD)and a shielding line 344. The first power supply signal line VDD1 and thesecond power supply signal line VDD3 are electrically connected to each other, and the first power supply signal line VDD1 and the third powersupply signal line VDD2 are electrically connected to each other. The second power supply line VDD3 includes a first power supply sub-line VDD31 extending along a first direction Y and a second power supply sub-line VDD32 extending along a second direction X.

The active semiconductor layer 310 can be formed by patterning a semiconductor material. The active semiconductor layer 310 can be used to fabricate channels for the drivingtransistor T1, the data writing transistor T2, the threshold compensationtransistor T3, the first light emitting control transistor T4, the second lightemitting control transistor T5, the first reset transistor T6 and the second reset transistor T7 as described above. The active semiconductor layer 310includes channels and source and drain regions of the transistors of the sub-pixels (i.e., the source region s and the drain region d shown in the secondcolor sub-pixel, for example), and a channel and source and drain regions ofeach transistor in the same pixel circuit are integrally formed. The active semiconductor layer 310 shown in FIG. 2 includes a channel 301 of a firstcolor sub-pixel, a channel 302 of a second color sub-pixel, and a channel303 of a third color sub-pixel.It should be noted that the active semiconductor layer can include anintegrally formed low temperature polysilicon layer, and the source regionand the drain region can become conductive by doping or the like to achieve electrical connection of the components. That is, the active semiconductor layer of each transistor of each sub-pixel is an overall pattern formed by p-silicon, and the transistors in the same pixel circuit include source and drainregions (i.e., source region s and drain region d) and channels, the channels of different transistors are separated by source and drain regions.In one embodiment, the active semiconductor layers in the pixel circuits of sub-pixels of different colors arranged along the first direction have noconnection relationship and are disconnected from each other. The active semiconductor layers in the pixel circuits of the sub-pixels of the same colorarranged along the second direction can be integrally arranged ordisconnected from each other. In one embodiment, the active semiconductor layer 310 can be made ofamorphous silicon, polysilicon, oxide semiconductor materials, or the like.It should be noted that, the above-mentioned source region and drain regioncan be regions doped with n-type impurities or p-type impurities.For example, a gate metal layer of the pixel circuit can include a first conductive layer and a second conductive layer. A gate insulating layer 103(as shown in FIG. 8 and FIG. 9) is formed on the above-mentioned active semiconductor layer 310 to protect the above-mentioned active semiconductor layer 310, and the active semiconductor layer 310 is disposedon the base substrate 100. FIG. 3 shows the first conductive layer 320 included in the display substrate. The first conductive layer 320 is disposedon the gate insulating layer so as to be insulated from the active semiconductor layer 310. The first conductive layer 320 can include asecond polar plate CC2 of the capacitor C, a scan signal line Ga1, a resetcontrol signal line Rst1, a light emitting control signal line EM1, a driving transistor T1, a data writing transistor T2, a threshold compensation transistor T3, and gate electrodes of a first light emitting control transistorT4, a second light emitting control transistor T5, a first reset transistor T6 and a second reset transistor T7. The scan signal line Ga1 includes a main body portion Ga11 of the scan signal line and a protruding portion Pprotruding from one side of the main body portion Ga11 of the scan signal line.For example, as shown in FIG. 3, the gate electrode of the data writingtransistor T2 can be the portion where the scan signal line Ga1 and the active semiconductor layer 310 overlap. The gate electrode of the first lightemitting control transistor T4 can be a first part where light emitting controlsignal line EM1 overlaps with the active semiconductor layer 310, the gate electrode of the second light emitting control transistor T5 can be a second part where the light emitting control signal line EM1 overlaps with theactive semiconductor layer 310. The gate electrode of the first resettransistor T6 is a first part where the reset control signal line Rst1 overlapswith the active semiconductor layer 310, and the gate electrode of the second reset transistor T7 is a second part where the reset control signal line Rst1 overlaps with the active semiconductor layer 310. The thresholdcompensation transistor T3 can be the thin film transistor with double gateelectrode structure, the first gate electrode of the threshold compensationtransistor T3 can be the portion where the scan signal line Ga1 overlaps with the active semiconductor layer 310, and the second gate electrode of the threshold compensation transistor T3 can be the part where the protrudingportion P of the scan signal line Ga1 overlaps with the active semiconductorlayer 310. As shown in FIGS. 1 and 3, the gate electrode of the drivingtransistor T1 can be the second polar plate CC2 of the capacitor C. It should be noted that the dotted-line rectangle boxes in FIG. 2 showthe parts where the first conductive layer 320 overlaps with the active semiconductor layer 310.For example, as shown in FIG. 3, the scan signal line Ga1, the resetcontrol signal line Rst1, and the light emitting control signal line EM1 are arranged in the second direction X. The scan signal line Ga1 is disposedbetween the reset control signal line Rst1 and the light emitting controlsignal line EM1. The signal line extending in the first direction means thatthe row of the signal line as a whole extends in the first direction, and an area of the part of the signal line extending in the first direction is much larger than an area of the part extending in the second direction. The signalline extending in the second direction means that the row of the signal line as a whole extends along the second direction, and an area of the part of thesignal line extending in the second direction is much larger than an area ofthe part extending in the first direction.For example, in the second direction X, the second polar plate CC2 ofthe capacitor C (i.e. the gate electrode of the driving transistor T1) is disposed between the scan signal line Ga1 and the light emitting controlsignal line EM1. The protruding portion P of the scan signal line Ga1 isdisposed on the side of the scan signal line Ga1 away from the light emittingcontrol signal line EM1.For example, as shown in FIG. 2, in the second direction X, the gate electrode of the data writing transistor T2, the gate electrode of the thresholdcompensation transistor T3, the gate electrode of the first reset transistor T6,and the gate electrode of the second reset transistor T7 are both disposed on a first side of the gate electrode of the driving transistor T1. The gate electrode of the first light emitting control transistor T4 and the gate electrode of the second light emitting control transistor T5 are both disposed on a second side of the gate electrode of the driving transistor T1. Forexample, in the examples shown in FIGS. 2-7, the first side and the secondside of the gate electrode of the driving transistor T1 of the pixel circuit ofthe first color sub-pixel are two sides of the gate electrode of the driving transistor T1 in the second direction X which are opposite with respect to each other. For example, as shown in FIGS. 2-7, in the XY plane, the firstside of the gate electrode of the driving transistor T1 of the pixel circuit ofthe first color sub-pixel can be the upper side of the gate electrode of thedriving transistor T1, and the second side of the gate electrode of the driving transistor T1 of the pixel circuit of the first color sub-pixel can be the lowerside of the gate electrode of the driving transistor T1. For the lower side, forexample, the side of the display substrate used to bind the driving chip is the lower side of the display substrate, and the lower side of the gate electrodeof the driving transistor T1 is the side of the gate electrode of the drivingtransistor T1 that is closer to the driving chip. The upper side is the oppositeside to the lower side, for example, the side of the gate electrode of the driving transistor T1 that is farther from the driving chip.For example, in some embodiments, as shown in FIGS. 2-7, in the firstdirection Y, the gate electrode of the data writing transistor T2 and the gateelectrode of the first light emitting control transistor T4 are both disposed ata third side of the gate electrode of the driving transistor T1, the first gate electrode of the threshold compensation transistor T3, the gate electrode ofthe second light emitting control transistor T5 and the gate electrode of thesecond reset transistor T7 are both disposed on a fourth side of the gate electrode of the driving transistor T1. For example, in the examples shownin FIGS. 2-7, the third side and the fourth side of the gate electrode of the driving transistor T1 of the pixel circuit of the first color sub-pixel are twosides of the gate electrode of the driving transistor T1 in the first directionY which are opposite with respect to each other. For example, as shown in FIGS. 2-7, the third side of the gate electrode of the driving transistor T1 of the pixel circuit of the first color sub-pixel can be the left side of the gate electrode of the driving transistor T1 of the pixel circuit of the first colorsub-pixel, and the fourth side of the gate electrode of the driving transistorT1 of the pixel circuit of the first color sub-pixel can be the right side of the gate electrode of the driving transistor T1 of the pixel circuit of the firstcolor sub-pixel. For the left side and the right side, for example, in the same pixel circuit, the data line is on the left side of the first power supply signalline VDD1, and the first power supply signal line VDD1 is on the right side of the data line.For example, a first insulating layer 104 (as shown in FIG. 8 and FIG. 9) is formed on the above-mentioned first conductive layer 320 to protect the above-mentioned first conductive layer 320. FIG. 4 shows the secondconductive layer 330 of the pixel circuit. The second conductive layer 330includes the first polar plate CC1 of the capacitor C, the reset power supply signal line Init1, the third power supply signal line VDD2 and the light shielding portion S. The third power supply signal line VDD2 is integrally formed with the first polar plate CC1 of the capacitor C. The first polar plateCC1 of the capacitor C and the second polar plate CC2 of the capacitor C at least partially overlap to form the capacitor C.For example, a second insulating layer 105 (as shown in FIG. 8 and FIG.9) is formed on the above-mentioned second conductive layer 330 to protectthe above-mentioned second conductive layer 330. FIG. 5 shows a source-drain metal layer 340 of the pixel circuit. The source-drain metal layer 340 includes a data line Vd, a first power supply signal line VDD1 and ashielding line 344. The data line Vd, the first power supply signal line VDD1and the shielding line 344 all extend along the second direction X. Theshielding line 344 and the data line Vd are disposed in the same layer and made of the same material, so that the shielding line and the data line can be formed in the same patterning process at the same time, eliminatingadditional patterning process for making the shielding line, therebysimplifying the production process of the display substrate, and loweringthe production cost. For example, the source-drain metal layer 340 furtherincludes a connection structure 341, a connection part 342 and a first electrode connection sub-structure 343 of the electrode connection structure.One end of the connection structure 341 is connected to the gate electrodeof the driving transistor T1, and the other end of the connection structure341 is connected to the source and drain regions of the thresholdcompensation transistor T3. FIG. 5 also shows exemplary locations of a plurality of via holesthrough which the source-drain metal layer 340 passes to connect to aplurality of film layers disposed between the source-drain metal layer 340and the base substrate. For example, the source-drain metal layer 340 isconnected to the active semiconductor layer 310 shown in FIG. 2 through via holes 381, 382, 384, 387 and 352, and the source-drain metal layer 340passes through the via holes 3832, 386, 385, 331 and 332 and connected tothe second conductive layer 330 shown in FIG. 4. The specific film layer where each via hole is disposed and the specific connection relationship willbe described in detail with reference to FIG. 7 later. For example, a third insulating layer 106 and a fourth insulating layer107 (as shown in FIGS. 8 and 9) are formed on the above-mentioned source- drain metal layer 340 to protect the above-mentioned source-drain metallayer 340. The organic light emitting element of each sub-pixel can bedisposed on a side of the third insulating layer and the fourth insulating layeraway from the base substrate.FIG. 6 shows the third conductive layer 350 of the pixel circuit. The third conductive layer 350 includes a second electrode connection sub-structure 353 of the electrode connection structure and second power supplysignal lines VDD3 distributed along the second direction X and the firstdirection Y respectively and intersect with one another. FIG. 6 also showsexemplary locations of a plurality of via holes 351 and 354 through which the third conductive layer 350 is connected to the source-drain metal layer340.FIG. 7 is a schematic diagram of the stacking positional relationship ofthe active semiconductor layer 310, the first conductive layer 320, thesecond conductive layer 330, the source-drain metal layer 340 and the thirdconductive layer 350 described above. As shown in FIGS. 2-7, the data lineVd is connected to the source region of the data writing transistor T2 in the active semiconductor layer 310 through at least one via hole (e.g., the viahole 381) in the gate insulating layer, the first insulating layer, and thesecond insulating layer. The first power supply signal line VDD1 communicates with the source region of the corresponding first lightemitting control transistor T4 in the active semiconductor layer 310 throughat least one via hole (e.g., the via hole 382) in the gate insulating layer, the first insulating layer, and the second insulating layer. As shown in FIGS. 2-7, one end of the connection structure 341 is connected to the drain region of the corresponding threshold compensationtransistor T3 in the active semiconductor layer 310 through at least one viahole (e.g., the via hole 384) in the gate insulating layer, the first insulatinglayer and the second insulating layer, and the other end of the connection structure 341 is connected to the gate electrode of the driving transistor T1 (i.e., the second polar plate CC2 of the capacitor C) in the first conductivelayer 320 through at least one via (e.g., the via hole 385) in the first insulating layer and the second insulating layer. One end of the connectionpart 342 is connected to the reset power supply signal line Init1 through a via hole (for example, the via hole 386) in the second insulating layer, andthe other end of the connection part 342 is connected to the drain region ofthe second reset transistor T7 in the active semiconductor layer 310 through at least one via (e.g., the via hole 387) in the gate insulating layer, the firstinsulating layer and the second insulating layer. The first electrodeconnection sub-structure 343 is connected to the drain region of the secondlight emitting control transistor T5 in the active semiconductor layer 310through at least one via hole (e.g., the via hole 352) in the gate insulating layer, the first insulating layer, and the second insulating layer. It should be noted that the source region and the drain region of the transistor mentionedin the embodiments of the present disclosure can be the same in structure,so the source region and the drain region of the transistor can beindistinguishable in structure. Therefore, the two are interchangeable as required.For example, as shown in FIGS. 2-7, the first power supply signal line VDD1 passes through at least one via hole (e.g., via hole 3832) in the secondinsulating layer between the second conductive layer 330 and the source-drain metal layer 340 and connected to the first polar plate CC1 of the capacitor C in the second conductive layer 330.For example, as shown in FIGS. 2-7, the shielding line 344 extendsalong the second direction X, and an orthographic projection of the shieldingline 344 on the base substrate is disposed between an orthographic projection of the driving transistor on the base substrate and an orthographic projection of the data line on the base substrate. For example, the shieldingline in the pixel circuit of the first color sub-pixel can reduce the influenceof the signal transmitted through the data line in the pixel circuit of the second color sub-pixel on the performance of the threshold compensationtransistor T3 of the first color sub-pixel, further, reduce the influence of the coupling between the gate electrode of the driving transistor of the first colorsub-pixel and the data line of the second color sub-pixel, and alleviate theproblem of crosstalk.For example, as shown in FIGS. 2-7, the shielding line 344 is connected to the reset power signal line Init1 through at least one via hole (e.g., the via hole 332) in the second insulating layer, except that the shielding line has afixed potential, and also makes the voltage of the initialization signal transmitted on the reset power supply signal line more stable, which is morebeneficial to the working performance of the pixel driving circuit. For example, as shown in FIGS. 2-7, the shielding line 344 iselectrically connected to the reset power signal line so that the shielding line has a fixed potential. The shielding line 344 can be electrically connected to the two reset power signal lines Init1 extending in the Y directionrespectively, and the two reset power signal lines Init1 are respectivelydisposed on two sides of the shielding line 344 along the X direction. Forexample, the two reset power supply signal lines correspond to the pixelcircuits of the nth row and the (n+1)th row respectively. For example, the shielding line 344 in the same column can be a whole shielding line, and the whole shielding line includes a plurality of sub-sections disposed between two adjacent reset power supply signal lines, andeach sub-section is respectively disposed within each pixel circuit area inthe column. For example, in addition to coupling the shielding line 344 with thereset power signal line, the shielding line 344 can also be coupled with thefirst power signal line, so that the shielding line 344 has the same fixedpotential as the first power signal line. For example, an orthographic projection of the shielding line 344 onthe base substrate is disposed between an orthographic projection of the threshold compensation transistor T3 on the base substrate and anorthographic projection of the data line Vd on the base substrate, so that theshielding line 344 can reduce the influence of the change in signaltransmitted on the data line on the performance of the thresholdcompensation transistor T3, further reduce the influence of the couplingbetween the gate electrode of the driving transistor and the data signal line Vd(n+1), and solve the problem of vertical crosstalk, so that when thedisplay substrate can achieve a better display effect when being used fordisplay. For example, the orthographic projection of the shielding line 344 onthe base substrate can be disposed between the orthographic projection of the connection structure 341 on the base substrate and the orthographicprojection of the data line on the base substrate. The orthographic projectionof the shielding line 344 on the base substrate T1 is disposed between the orthographic projection of the driving transistor T1 on the base substrate andthe orthographic projection of the data line on the base substrate. The above-mentioned configuration can well reduce a first crosstalkgenerated between the data line and the threshold compensation transistor, and a second crosstalk generated between the data line and the connection structure, thereby reducing indirect crosstalk to the driving transistor due to the first crosstalk and the second crosstalk. In addition, the above-mentioned configuration can also reduce direct crosstalk between the data line and thedriving transistor, thereby better ensuring the working performance of the display substrate. For example, the shielding line 344 is not limited to the above-mentioned configuration, and the shielding line 344 can also be only coupled with the reset power supply signal line corresponding to the pixel circuit in the nth row, or only with the reset power supply signal line correspondingto the pixel circuit in the (n+1)th row. Moreover, the length of the shielding line 344 extending in the second direction X can also be set according to actual needs. For example, the pixel circuit of a sub-pixel of a color also includes alight shielding portion S. The light shielding portion S and the shielding line344 are disposed in different layers, and an orthographic projection of the light shielding portion S on the base substrate has overlap with an orthographic projection of the shielding line 344 on the base substrate. Theshielding line 344 is connected to the light shielding portion S in the secondconductive layer 330 through the via hole 331 in the second insulating layer, so that the light shielding portion S has a fixed potential, thereby betterreducing coupling effect between the threshold compensation transistor T3 and other conductive patterns nearby, making the working performance ofthe display substrate more stable.For example, the light shielding portion S has overlap with the active semiconductor layer 310 between and the two gate electrodes of thethreshold compensation transistor T3, to prevent the active semiconductorlayer 310 from being illuminated to change characteristics, such as thevoltage of this part of the active semiconductor layer is prevented from changing to prevent crosstalk. This example schematically shows that the light shielding portion beingconnected to the shielding line, but it is not limited to this, and the two can also be in disconnection.For example, as shown in FIGS. 2-7, the second power supply signalline VDD3 is connected to the first power supply signal line VDD1 through at least one via hole 351 in the third insulating layer and the fourth insulatinglayer, and the second electrode connection sub-structure 353 is connected to the first electrode connection sub-structure 343 through the via hole 354 in the third insulating layer and the fourth insulating layer. For example, the third insulating layer can be a passivation layer, the fourth insulating layer can be a planarization layer, and the third insulatinglayer is disposed between the fourth insulating layer and the base substrate.The fourth insulating layer can be an organic layer, and the thickness of theorganic layer is thicker than that of the inorganic layers such as thepassivation layer. For example, the via hole 351 and the via hole 354 are both nested via holes. That is, the via hole 351 includes a first via hole in the third insulatinglayer and a second via hole in the fourth insulating layer, with the positionof the first via hole in the third insulating layer being opposite to the positionof the second via hole in the fourth insulating layer, and an orthographicprojection of the second via holes in the fourth insulating layer on the base substrate being located within an orthographic projection of the first via hole in the third insulating layer on the base substrate.For example, the second power supply signal lines VDD3 are distributed in a grid form. An orthographic projection of the second powersupply sub-line VDD32 of the second power supply signal line VDD3extending along the X direction on the base substrate is substantially coincides with an orthographic projection of the first power supply line VDD1 on the base substrate, or the orthographic projection of the first powersupply line VDD1 on the base substrate is located within the orthographicprojection of second power supply sub-line VDD32 on the base substrate.In addition, the power supply signal line VDD3 being electrically connected to the first power supply signal line VDD1 can reduce the voltage drop ofthe first power supply signal line VDD1, thereby improving the uniformityof the display device.For example, the second power supply signal line VDD3 can be made of the same material as the source-drain metal layer. For example, as shown in FIG. 5, the first electrode connection sub-structures 343 of the first color sub-pixel, the second color sub-pixel and thethird color sub-pixel are all block structures. The subsequently formed first electrode of a sub-pixels of a color will be connected to the correspondingsecond electrode connection sub-structure 353 through a via hole so as to be connected to the drain region of the second light emitting control transistorT5.This embodiment includes, but is not limited to, the position of the second electrode connection sub-structure in a sub-pixel of a color isdetermined according to the arrangement of the organic light emitting elements and the position of the light emitting region.For example, FIG. 8 is a schematic diagram of a partial cross-sectionalstructure of the display substrate where the layer shown in FIG. 7 is disposed,and FIG. 7 only illustrates part of the film layers in FIG. 8. As shown in FIGS. 7 and 8, in the active semiconductor layer in the pixel circuit of thesecond color sub-pixel 120, a gate insulating layer 103 is disposed on a side of the second electrode (e.g., the drain electrode T5d) of the second light emitting control transistor T5 away from the side of the base substrate 100,a light emitting control signal line EM1 is provided on a side of the gateinsulating layer 103 away from the base substrate 100, a first insulating layer104 is disposed on a side of the light emitting control signal line EM1 awayfrom the base substrate 100, a third power supply signal line VDD2 is disposed on a side of the first insulating layer 104 away from the base substrate 100, a second insulating layer 105 is disposed on a side of the thirdpower supply signal line VDD2 away from the base substrate 100, and a first electrode connection sub-structure 343 is disposed on a side of thesecond insulating layer 105 away from the base substrate 100. The first electrode connection sub-structure 343 of the second color sub-pixel 120 isconnected to the second electrode T5d of the second light emitting control transistor T5 in the active semiconductor layer 310 through the via hole 352in the gate insulating layer 103, the first insulating layer 104 and the secondinsulating layer 105. The first electrode connection sub-structure 343 has overlap with both the third power supply signal line VDD2 and the lightemitting control signal line EM1. On a side of the first electrode connectionsub-structure 343 away from the base substrate 100 is provided with a thirdinsulating layer 106 and a fourth insulating layer 107 in this order, and on a side of the fourth insulating layer 107 away from the base substrate 100 is provided with a second electrode connection sub-structure 353 and a second power supply signal line VDD3. The second power supply signal line VDD3 has overlap with the third power supply signal line VDD2. The second electrode connection sub-structure 353 is connected to the first electrodeconnection sub-structure 343 through a nested via hole 354 in the third insulating layer 106 and the fourth insulating layer 107, thereby realizing connection with the second light emitting control transistor.For example, as shown in FIG. 8, the data line Vd is connected to thesource electrode T2s of the data writing transistor T2 through the via hole381 in the gate insulating layer 103, the first insulating layer 104 and the second insulating layer 105. One end of the connection structure 341 is connected to the drain electrode T3d of the threshold compensation transistor T3 through the via hole 384 in the gate insulating layer 103, the first insulating layer 104 and the second insulating layer 105, and the otherend of the connection structure 341 is connected to the gate electrode of thedriving transistor T1 (i.e., the second polar plate CC2 of the capacitor C)through the via hole 385 in the first insulating layer 104, the second insulating layer 105. The channel T1c of the driving transistor T1 is disposed on the side of the gate electrode facing the base substrate 100, and has nooverlap with the via hole 385, the source electrode T1d of the drivingtransistor T1 has overlap with both the its gate electrode and the firstelectrode polar plate CC1 of the capacitor C. For example, FIG. 9 is a schematic diagram of a partial cross-sectionalstructure of the display substrate where the layer shown in FIG. 7 is disposed,and FIG. 7 only illustrates a part of the film layers in FIG. 9. As shown in FIGS. 7-9, the difference between the first color sub-pixel 110 and the second color sub-pixel 120 is that in the second color sub-pixel 120, an orthographic projection of the second electrode connection sub-structure353 on the base substrate 100 has no overlap with an orthographic projectionof the second electrode T5d of the second light emitting control transistorT5 thereof on the base substrate 100, while in the first color sub-pixel 130,an orthographic projection of the second electrode connection sub-structure 353 on the base substrate 100 has overlap with an orthographic projectionof the second electrode T5d of the second light emitting control transistor T5 thereof on the base substrate 100. In the first color sub-pixel 110, the first electrode connection sub-structure 343 has no overlap with either thethird power supply signal line VDD2 or the light emitting control signal line EM1. In the first color sub-pixel 110, the channel T1c of the drivingtransistor T1 is disposed on a side of the gate electrode of the drivingtransistor T1 facing the base substrate 100 and has overlap with the via hole385. From this, it can be seen that the width of the channel of the drivingtransistor of the first color sub-pixel is larger than the width of the channel of the second color sub-pixel.For example, as shown in FIGS. 2-7, in the second direction X, the scan signal line Ga1, the reset control signal line Rst1 and the reset power supply signal line Init1 are all disposed on a first side of the gate electrode of the driving transistor T1 of the pixel circuit of the first color sub-pixel, the light emitting control signal line EM 1 is disposed on a second side of the drivingtransistor T1 of the pixel circuit of the first color sub-pixel. For example, the scan signal line Ga1, the reset control signal line Rst1,the light emitting control signal line EM1, and the reset power supply signal line Init1 all extend in the first direction Y, and the data line Vd extends inthe second direction X.It should be noted that the positional arrangement relationship of the driving circuit, the first light emitting control circuit, the second lightemitting control circuit, the data writing circuit, the storage circuit, thethreshold compensation circuit and the reset circuit in each pixel circuit isnot limited to the examples shown in FIGS. 2-7, the positions of the drivingcircuit, the first light emitting control circuit, the second light emitting control circuit, the data writing circuit, the storage circuit, the thresholdcompensation circuit and the reset circuit can be specifically set accordingto actual application requirements.For example, as shown in FIGS. 2-9, the first electrode 11 of the firstcolor sub-pixel is connected to the second electrode connection sub- structure 353 through the via hole (not shown) of the fifth insulating layer, thereby realizing connection with the drain region of the second light emitting control transistor T5. Similarly, the first electrode 13 of the organiclight emitting element of the third color sub-pixel is connected to the secondelectrode connection sub-structure 353 through the via hole (not shown) of the fifth insulating layer, so as to realize the connection with the drain regionof the second light emitting control transistor T5. The first electrode 12 ofthe second color sub-pixel is connected to the second electrode connection sub-structure 353 through the via hole of the fifth insulating layer, and thenconnected to the second electrode connection sub-structure 343, so as torealize the connection with the drain region of the second light emittingcontrol transistor T5. The embodiment of the present application provides a novel pixelarrangement, which will be introduced below. As shown in FIG. 7, an orthographic projection of the pixel opening 21 of the first color sub-pixelon the base substrate has no overlap with an orthographic projection of the channel 301 of the driving transistor of the first color sub-pixel on the base substrate. An orthographic projection of the pixel opening 22 of the second color sub-pixel on the base substrate has no overlap with an orthographicprojection of the channel 302 of the driving transistor of the second colorsub-pixel on the base substrate. An orthographic projection of the pixelopening 23 of the third color sub-pixel on the base substrate has no overlap with an orthographic projection of the channel 303 of the driving transistorof the third color sub-pixel on the base substrate. The above-mentioned arrangement of pixels is different from the arrangement of pixels in displaypanels existing in the art.In one embodiment, the plurality of sub-pixels are divided into aplurality of pixel groups, each of the pixel groups including a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. At least one ofthe pixel groups includes two rows of sub-pixels arranged along the first direction, wherein one row of sub-pixels arranged along the first direction includes first color sub-pixels and third color sub-pixels which are alternately arranged, and the other row of sub-pixels arranged along the firstdirection includes second color sub-pixels. Here, a row of sub-pixels arranged along the first direction refers to that the organic light emittingelements of the sub-pixels are arranged along the first direction.In one embodiment, the first electrode of the sub-pixel or the pixel opening can be used as a reference to divide the plurality of sub-pixels intoa plurality of pixel groups. In other embodiments, the pixel circuit of thesub-pixel can also be used as a reference to divide the plurality of sub-pixels into a plurality of pixel groups. FIG. 7A is a schematic diagram of part ofthe film layers of the plurality of pixel groups 101 in the display substrate where the layer shown in FIG. 7 is disposed, and illustrates the arrangementof the pixel openings of the plurality of pixel groups 101. Referring to FIG. 7A, the pixel openings of the same pixel group 101 are divided into tworows, wherein one row of first electrodes arranged along the first direction include pixel openings 21 of the first color sub-pixels and pixel openings 23of the third color sub-pixels which are alternately arranged, and the otherrow of first electrodes arranged along the first direction include pixel openings 22 of the second color sub-pixels. In the embodiment shown in FIG. 7A, the pixel circuits of the same pixel group 101 are disposed in the same row. In other embodiments, the pixel circuits of the same pixel group101 can also be disposed in different rows.In one embodiment, referring to FIG. 7, any one of the orthographic projection of the pixel opening 21 of the first color sub-pixel on the base substrate, the orthographic projection of the pixel opening 22 of the secondcolor sub-pixel on the base substrate or the orthographic projection of the pixel opening 23 of the third color sub-pixel on the base substrate has nooverlap with any one of the orthographic projection of the channel 301 of the driving transistor of the first color sub-pixel on the base substrate, the orthographic projection of the channel 302 of the driving transistor of thesecond color sub-pixel on the base substrate, or the orthographic projectionof the channel 303 of the driving transistor of the third color sub-pixel onthe base substrate. When displayed at high temperature, the lifespan of the display panel existing in the art is short, and a color shift phenomenon tends to occurduring display. The inventor found that the reason for this problem is thatwhen the display panel is displaying, the current of the driving transistor ofthe blue sub-pixel is relatively large. For example, the current of the drivingtransistor of the blue sub-pixel is 2.15 times that of the current of the drivingtransistor of the green sub-pixel. The channel of the driving transistor of theblue sub-pixel overlaps with the organic light emitting element of the greensub-pixel, resulting in a large temperature rise of the organic light emittingelement of the green sub-pixel, which in turn causes the green sub-pixel todecay too quickly and shortens the lifespan. In addition, the brightnessattenuation speeds of the sub-pixels of different colors are quite different, so that the color shift phenomenon occurs in the display screen. The above-mentioned arrangement of the sub-pixels can prevent the driving transistorof the second color sub-pixel from increasing the temperature of the organiclight emitting element of the first color sub-pixel or the third color sub-pixeltoo much and resulting in an excessively fast luminance decay of the organic light emitting element. It helps to improve the lifespan of sub-pixels, canreduce the difference in the brightness decay speeds of sub-pixels ofdifferent colors and alleviate the color shift problem of the display substrate.Since the pixel openings of sub-pixels of each color and the channels of thedriving transistor do not overlap, so that the temperature of the organic light emitting elements of the sub-pixels of the colors can be lowered, and theservice life and color shift problems of the display panel can be improved.In one embodiment, in at least one pixel group, a distance between the channel of the driving transistor of the sub-pixel and the scan signal line in the second direction X ranges from 1 μm to 50 μm. Specifically, a distance between the channel 301 of the driving transistor of the first color sub-pixeland the scan signal line Ga1 in the second direction ranges from 1 μm to 50μm. A distance between the channel 302 of the driving transistor of thesecond color sub-pixel and the scan signal line Ga1 in the second direction ranges from 1 μm to 50 μm. A distance between the channel 303 of thedriving transistor of the third color sub-pixel and the scan signal line Ga1 inthe second direction ranges from 1 μm to 50 μm.Further, in at least one pixel group, the distance between the channel ofthe driving transistor of the sub-pixel and the scan signal line in the second direction ranges from 10 μm to 50 μm. For example, the distance between the channel of the driving transistor of the sub-pixel and the scan signal line in the second direction is 10 μm, 15 μm, 20 μm, 25 μm, 30 μm, 35 μm, 40μm, 45 μm, 50 μm, and so on.In one embodiment, as shown in FIG. 7, in at least one of the pixelgroups, the orthographic projection of the pixel opening corresponding to each of the sub-pixels on the base substrate has no overlap with theorthographic projection of the gate electrode of the driving transistor of any of the sub-pixels on the base substrate; or, the orthographic projection of the pixel opening corresponding to each of the sub-pixels on the base substrate has an overlapping region with the orthographic projection of the gateelectrode of the driving transistor of any of the sub-pixels on the base substrate, and a ratio of the area of the overlapping region to the area of the gate electrode is not more than 10%. When the temperature of the drivingtransistor increases, the heat generated by the driving transistor is mainly transmitted to the organic light emitting element of the sub-pixel throughthe gate electrode. With the orthographic projection of the pixel openingcorresponding to each of the sub-pixels on the base substrate having no overlap with the orthographic projection of the gate electrode of the drivingtransistor of any of the sub-pixels on the base substrate; or, the orthographic projection of the pixel opening corresponding to each of the sub-pixels onthe base substrate having a relatively small area of an overlapping region with the orthographic projection of the gate electrode of the driving transistor of any of the sub-pixels on the base substrate, it can effectively reduce the amount of heat generated by the driving transistor that is transmitted to the organic light emitting element, and the temperature of theorganic light emitting element can be prevented from rising too much, whichwould otherwise cause the organic light emitting element to decay too quickly and shorten its service life. It can improve the service life of subpixelsand alleviate the color shift problem of display substrate.Further, in the embodiment shown in FIG. 7, the distance between thegate electrode of the driving transistor of the sub-pixel and the scan signal line Ga1 in the second direction ranges from 2 μm to 10 μm. The distance between the gate electrode of the driving transistor of the sub-pixel and thescan signal line Ga1 in the second direction is, for example, 2 μm, 4 μm, 6μm, 8 μm, 10 μm, and so on.In one embodiment, referring to FIG. 10, in at least one pixel group, theorthographic projection of the scan signal line Ga1 in the second direction X has overlap with the orthographic projection of the gate electrode of thedriving transistor of the sub-pixel in the second direction X, where the second direction X is perpendicular to the first direction Y. The orthographic projections of the scan signal line and the gate electrode of the drivingtransistor on the second direction X refer to the orthographic projections ofthe scan signal line and the gate electrode of the driving transistor on a straight line extending along the second direction X. As shown in FIG. 10, the orthographic projection of the scan signal line Ga1 in the seconddirection X has overlap with the orthographic projection of the gateelectrode 321 of the driving transistor of the first color sub-pixel in thesecond direction X. The orthographic projection of the scan signal line Ga1is in the second direction X has overlap with the orthographic projection of the gate electrode 322 of the driving transistor of the second color sub-pixelin the second direction X. The orthographic projection of the scan signalline Ga1 in the second direction X has overlap with the orthographic projection of the gate electrodes 323 of the driving transistor of the thirdcolor sub-pixel in the second direction X. Such configuration can make the arrangement of the components in the display substrate relatively closer toone another, which can increase the density of the sub-pixels in the displaysubstrate.In one embodiment, as shown in FIG. 10, the scan signal line Ga1includes a main body portion Ga11 of the scan signal line and a protruding portion P protruding from one side of the main body portion Ga11 of the scan signal line. The main body portion Ga11 of the scan signal line extendsalong the first direction Y as a whole, and the protruding portion P extendsalong the second direction X.

In the same scan signal line, in the first direction,the protruding portion P and the connection part 325 are disposed on both sides of the first scan sub-line 324. In the illustrated embodiment, theprotruding portion P is disposed on the side of the first scan sub-line 324close to the first reset control signal line Rst1, and the connection part 325is disposed on the side of the first scan sub-line 324 away from the first reset control signal line Rst1. In other embodiments, the connection part 325 canbe disposed on the side of the first scan sub-line 324 close to the first resetcontrol signal line Rst1, and the protruding portion P can be disposed on theside of the first scan sub-line 324 away from the first reset control signal line Rst1. The first scan sub-line 324 is connected to the pixel circuit of the firstcolor sub-pixel, the second scan sub-line 326 is connected to the pixel circuitof the second color sub-pixel, and extension direction of part of theconnection part 325 intersects with the extension direction of the first scan sub-line 324. In the threshold compensation transistor, the first gate electrode is the part of the connection part 325 that overlaps with theorthographic projection of the active semiconductor layer on the base substrate.Further, the orthographic projection of the connection part 325 in thesecond direction X has overlap with the orthographic projection of the gate electrode of the driving transistor of the sub-pixel in the second direction X. As shown in FIG. 10, the orthographic projection of the connection part 325in the second direction X has overlap with all of the orthographic projectionof the gate electrode 321 of the first color sub-pixel in the second directionX, the orthographic projection of the gate electrode 322 of the second colorsub-pixel in the second direction X and the orthographic projection of thegate electrode 323 of the third color sub-pixel in the second direction X. In one embodiment, as shown in FIG. 10 and FIG. 10A, the connectionpart 325 includes a first connection sub-part 3251, a second connection sub-part 3252 and a third connection sub-part 3253 that are connected insequence.

In the threshold compensation transistor, the first gate electrode is a part of the second connection sub-part 3252 thatoverlaps with the orthographic projection of the active semiconductor layeron the base substrate.In one embodiment, as shown in FIG. 2 and FIG. 2A, the active semiconductor layer 310 includes a first section 311, a second section 312, a third section 313 and a fourth section 314 that are connected in sequence. The second section 312, the fourth section 314 and the main body portionGa11 of the scan signal line extend along the first direction Y, the firstsection 311 and the third section 313 extend in the second direction X. The second gate electrode of the threshold compensation transistor T3 is the part of the protruding portion P that overlaps with the orthographic projection ofthe fourth section 314 on the base substrate. The gate electrode of the resettransistor includes a part where the reset control signal line Rst1 overlaps with the orthographic projection of the first section 311 on the base substrate. Specifically, the first reset transistor T6 includes two gate electrodes, one of which includes the part of the reset control signal line Rst1 that overlaps theorthographic projection of the first section 311 on the base substrate. Sucharrangement is convenient for the threshold compensation transistor T3 andthe first reset transistor T6 to form a double gate electrode structure.Further, as shown in FIG. 10, in at least one pixel group, theorthographic projection of the gate electrode of the driving transistor of atleast one sub-pixel on the base substrate has overlap with the orthographic projection of its corresponding pixel opening on the base substrate.Specifically, the orthographic projection of the gate electrode 321 of thedriving transistor of the first color sub-pixel on the base substrate has overlap with the orthographic projection of its corresponding pixel opening21 on the base substrate; the orthographic projection of the gate electrode 323 of the driving transistor of the third color sub-pixel on the base substratehas overlap with the orthographic projection of its corresponding pixel opening 23 on the base substrate.Further, the part where the orthographic projection of the gate electrodeof at least the sub-pixel on the base substrate overlaps with the corresponding pixel opening on the base substrate has a size in the seconddirection X ranging from 0 to 30 μm. In the embodiment shown in FIG. 10,the orthographic projections of the gate electrode of the first color sub-pixel,the gate electrode of the second color sub-pixel and the gate electrode of the third color sub-pixel on the base substrate each has an overlapping part with the corresponding pixel opening on the base substrate of a size larger than 0in the second direction X.In one embodiment, as shown in FIG. 11, the connection structure 341includes a first portion 3411 and a second portion 3412 connected to the firstportion 3411. The orthographic projection of the first portion 3411 on the base substrate and the orthographic projection of the protruding portion Pon the base substrate are located on the same side of the orthographicprojection of the main body portion Ga11 of the scan signal line on the basesubstrate. The length of the first portion 3411 in the second direction X is larger than the length of the protruding portion P in the second direction X.Here, in the second direction X, the orthographic projection of the main body portion Ga11 of the scan signal line on the base substrate includes twoopposite sides (for example, the upper side and the lower side), and theorthographic projection of the first portion 3411 on the base substrate and the orthographic projection of the protruding portion P on the base substratebeing located on the same side of the orthographic projection of the mainbody portion Ga11 of the scan signal line on the base substrate refers to that both the orthographic projection of the first portion 3411 on the base substrate and the orthographic projection of the protruding portion P on the base substrate being located on the upper side, or the lower side of the orthographic projection of the main body portion Ga11 of the scan signalline on the base substrate.

Such arrangement can facilitate connecting the end of the first portion 3411 to the gate electrode of the driving transistor T1.Further, the size of the connection structure 341 in the second direction X ranges from 35 μm to 70 μm. Scuh arrangement ensures that both ends of the connection structure 341 are electrically connected to the gate electrodeof the driving transistor T1 in the first conductive layer 320 and the source and drain regions of the threshold compensation transistor T3 in the active semiconductor layer 310 respectively. In some embodiments, the size of the connection structure 341 in the second direction X is 35 μm, 40 μm, 45 μm,50 μm, 55 μm, 60 μm, 65 μm, 70 μm, and so on.In one embodiment, as shown in FIG. 7 and FIG. 10, the orthographic projection of the first electrode 12 of at least one of the second color sub-pixels on the base substrate has overlap with the orthographic projection ofthe reset control signal line Rst1 on the base substrate and the orthographicprojection of the scan signal line Ga1 on the base substrate overlap. In someembodiments, the orthographic projection of the first electrode 12 of eachsecond color sub-pixel of the display panel on the base substrate has overlapwith the orthographic projection of one reset control signal line Rst1 on thebase substrate and the orthographic projection of one scan signal line Ga1on the base substrate. Such arrangement helps to increase the pixel densityof the display substrate.In one embodiment, the size of the first color sub-pixel in the firstdirection Y ranges from 35 μm to 110 μm, and the size of the first color sub- pixel in the second direction X ranges from 20 μm to 60 μm. The size of thesecond color sub-pixel in the first direction Y ranges from 35 μm to 120 μm,and the size of the second color sub-pixel in the second direction X rangesfrom 20 μm to 80 μm. The size of the third color sub-pixel in the firstdirection in Y ranges from 35 μm to 70 μm, and the size of the third color sub-pixel in the second direction X ranges from 20 μm to 60 μm. The sizeof the sub-pixel in the first direction refers to its maximum size in the firstdirection Y, and the maximum size of the sub-pixel in the first direction Y refers to the maximum size of an overlapping part of the orthographic projection of the pixel opening of the sub-pixel on the base substrate and the orthographic projection of the first electrode on the base substrate in the firstdirection Y. The size of the sub-pixel in the first direction X refers to itsmaximum size in the second direction X. The maximum size of the sub-pixelin the second direction X refers to the maximum size of an overlapping part of the orthographic projection of the pixel opening of the sub-pixel on the base substrate and the orthographic projection of the first electrode on thebase substrate in the first direction Y. In some examples, the size of the first color sub-pixel in the firstdirection Y is, for example, 35 μm, 45 μm, 55 μm, 65 μm, 75 μm, 85 μm, 95 μm, 105 μm, 110 μm, and so on.

Further, the area of the second color sub-pixel is larger than the area ofthe first color sub-pixel, and the area of the first color sub-pixel is larger than the area of the third color sub-pixel. Such arrangement can reduce thedifference in the lifetimes of the sub-pixels of each color. The embodiment of the present application also provides another new pixel arrangement. Referring to FIGS. 12 to 16, the orthographic projectionof the pixel opening of at least one sub-pixel on the base substrate has overlap with the orthographic projection of the channel of its drivingtransistor on the base substrate, and the orthographic projection of the pixelopening 22 of at least one of the second color sub-pixels in the first direction has overlap with the orthographic projection of the pixel opening 21 of thefirst color sub-pixel in the first direction Y and the orthographic projection of the pixel opening 23 of the third color sub-pixel in the first direction Y, and the orthographic projection of the pixel opening 22 of at least one of the second color sub-pixels in the second direction X has no overlap with eitherthe orthographic projection of the pixel opening 21 of the first color sub-pixel in the second direction X or the orthographic projection of the pixel opening 23 of the third color sub-pixel in the second direction X, where the first direction Y intersects with the second direction X. The pixelarrangement provided by the embodiments of the present application is different from the pixel arrangement in the display panel existing in the art. The orthographic projection of the pixel opening on the first direction Y refers to the orthographic projection of the pixel opening on a straight lineextending along the first direction Y. In one embodiment, as shown in FIG. 16, the orthographic projectionof the pixel opening 21 of the first color sub-pixel on the base substrate hasoverlap with the orthographic projection of the channel 301 of the driving transistor thereof on the base substrate, the orthographic projection of the pixel opening 23 of the third color sub-pixel on the base substrate hasoverlap with the orthographic projection of the channel 303 of the drivingtransistor thereof on the base substrate, and the orthographic projection ofthe pixel opening 22 of the second color sub-pixel on the base substrate hasoverlap with the orthographic projection of the channel 302 of the drivingtransistor thereof on the base substrate. Further, as shown in FIG. 16, the orthographic projection of the channel301 of the driving transistor of the first color sub-pixel on the base substrate falls within the orthographic projection of the pixel opening 21 on the base substrate, the orthographic projection of the channel 302 of the drivingtransistor of the second color sub-pixel on the base substrate falls within the orthographic projection of the pixel opening 22 on the base substrate, andthe orthographic projection of the channel 303 of the driving transistor ofthe third color sub-pixel on the base substrate falls within the orthographicprojection of the pixel opening 23 on the base substrate.In other embodiments, in the first color sub-pixel, the second color sub- pixel and the third color sub-pixel, only orthographic projections of the pixelopenings of the sub-pixels of one color or the sub-pixels of two colors onthe base substrate have overlap with the orthographic projection of thechannel of the driving transistor thereof on the base substrate.In one embodiment, as shown in FIG. 16, the orthographic projection of the pixel opening 21 of the first color sub-pixel on the base substrate hasno overlap with either the orthographic projection of the channel 302 of thedriving transistor of the second color sub-pixel on the base substrate or the orthographic projection of the channel 303 of the driving transistor of thethird color sub-pixel on the base substrate. The orthographic projection ofthe pixel opening 22 of the second color sub-pixel on the base substrate hasno overlap with either the orthographic projection of the channel 301 of thedriving transistor of the first color sub-pixel on the base substrate or the orthographic projection of the channel 303 of the driving transistor of thethird color sub-pixel on the base substrate. The orthograph30 ic projection ofthe pixel opening 23 of the third color sub-pixel on the base substrate hasno overlap with either the orthographic projection of the channel 301 of thedriving transistor of the first color sub-pixel on the base substrate or the orthographic projection of the channel 302 of the driving transistor of thesecond color sub-pixel on the base substrate. In such arrangement, theorthographic projection of the channel of the driving transistor of each sub-pixel on the base substrate only has overlap with the orthographic projection of its pixel opening on the base substrate, and has no overlap with theorthographic projection of the pixel opening of other sub-pixels on the base substrate. This is more helpful to reduce the difference in the luminancedecay speed of the organic light emitting elements of each sub-pixel, thereby alleviating the color shift problem of the display substrate. In another embodiment of the present application, the orthographicprojection of the channel of the driving transistor of the first color sub-pixel on the base substrate and the orthographic projection of the channel of the driving transistor of the second color sub-pixel on the base substrate are located within the orthographic projection of the pixel opening corresponding to the second color sub-pixel on the base substrate. The orthographic projection of the channel of the driving transistor of the third color on the base substrate is located within the orthographic projection ofthe pixel opening corresponding to the third color sub-pixel on the base substrate. Such arrangement can prevent the driving transistor of the second color sub-pixel with a larger driving current from increasing the temperatureof the organic light emitting element of the first color sub-pixel too much,which otherwise would cause an excessively fast luminance decay rate anda shortened life of the first color sub-pixel. The problem can be avoided that the luminance decay speed of the first color sub-pixel is significantlydifferent from the luminance decay speed of the second color sub-pixel andthe third color sub-pixel, and the color shift phenomenon of the displaysubstrate can be alleviated.In yet another embodiment of the present application, the orthographic projection of the channel of the driving transistor of the second color sub- pixel on the base substrate has no overlap with the orthographic projectionof the pixel opening corresponding to the first color sub-pixel on the basesubstrate, the orthographic projection of the pixel opening corresponding to the second color sub-pixel on the base substrate, and the orthographic projection of the pixel opening corresponding to the third color sub-pixel onthe base substrate. In such arrangement, the driving transistors of the second color sub-pixels with larger driving currents have less influence on the organic light emitting elements of the respective color sub-pixels, which is more helpful to improve the service life of the display substrate and alleviatethe color shift problem of the display substrate.Further, the orthographic projection of the channel of the drivingtransistor of the first color sub-pixel on the base substrate and the orthographic projection of the channel of the driving transistor of the third color on the base substrate are both located within the orthographicprojection of the pixel opening corresponding to the second color sub-pixel on the base substrate. Alternatively, the orthographic projection of the channel of the driving transistor of the first color sub-pixel on the base substrate is located within the orthographic projection of the pixel openingcorresponding to the second color sub-pixel on the base substrate, and the orthographic projection of the channel of the driving transistor of the third color on the base substrate is located within the orthographic projection ofthe pixel opening corresponding to the third color sub-pixel on the base substrate.In one embodiment, the plurality of sub-pixels are divided into aplurality of pixel groups, each of the pixel groups including a first color sub-pixel, a second color sub-pixel and a third color sub-pixel.

Further, in the seconddirection X, the distance from the channel 303 of the driving transistor ofthe third color sub-pixel to the scan signal line Ga1 is approximately equalto the distance from the channel 301 of the driving transistor of the first color sub-pixel to the scan signal line Ga1. Such arrangement is morehelpful to avoid overlap between the orthographic projections of the channel302 of the driving transistor of the second color sub-pixel and of the pixel opening of the first color sub-pixel on the base substrate.Further, in at least one pixel group, in the second direction X, the distance from the channel 302 of the driving transistor of the second colorsub-pixel to the scan signal line Ga1 is longer than the distance from thechannel 301 of the driving transistor of the first color sub-pixel to the scansignal line Ga1.

By setting the area of thesecond polar plate CC12 of the second color sub-pixel larger than the areaof the second polar plate CC11 of the first color sub-pixel and the secondpolar plate CC13 of the third color sub-pixel, the second polar plate CC12of the second color sub-pixel can cover the channel of driving transistor.
