As described above, data signal line is electrically connected with image element circuit structure 20 and transmits data electricity to image element circuit structure 20
Signal is pressed, scan signal line is electrically connected with image element circuit structure 20 and transmits scanning voltage signal, number to image element circuit structure 20
It is pulse signal according to voltage signal and scanning voltage signal.A data signal wire is usually electric with a row image element circuit structure 20
Connection, a scan signal line are usually electrically connected with one-row pixels circuit structure 20, then data signal line and corresponding each picture
When plain circuit structure 20 is electrically connected, it can generate overlapping or be disposed adjacent, scanning letter with the signal area in image element circuit structure 20
When number line is electrically connected with corresponding each image element circuit structure 20, can and the signal area in image element circuit structure 20 generate it is overlapping
Or it is disposed adjacent.Signal area described herein is overlapping with data signal line (or scan signal line) in image element circuit structure 20
Or the region for thering is signal to circulate being disposed adjacent.
In the present embodiment, the optional data signal line that pulse signal is provided to several image element circuit structures 20 is the first signal wire
Line1, optional with driving transistor Tc is electrically connected in image element circuit structure 20 signal area is the first signal area Q1.Or
Person, optional to provide the scan signal line of pulse signal as the first signal wire Line1 to several image element circuit structures 20, optional and pixel
The signal area that driving transistor Tc is electrically connected in circuit structure 20 is the first signal area Q1.As shown in Fig. 2, optional first letter
Number region Q1 is electrically connected with the grid of driving transistor Tc.
The signal of first signal wire Line1 outputs is pulse signal, and the first signal wire Line1 and the first signal area Q1 are produced
When life is overlapping or is disposed adjacent, signal coupling is easily generated between the first signal wire Line1 and the first signal area Q1, causes to go here and there
It disturbs.Influence of the crosstalk to organic light emitting display panel is negative.
By taking the first signal area Q1 shown in Fig. 2 as an example.When the signal of the first signal wire Line1 outputs is high level, the
Coupling between one signal wire Line1 and the first signal area Q1 causes the current potential of the first signal area Q1 to increase i.e. driving crystal
The grid potential raising of pipe Tc (P-type transistor), then driving transistor Tc in the conduction state may be ended, and shone
Stage can cause light emitting structure 10 not shine, and influence the display effect of organic light emitting display panel.When the first signal wire Line1 is defeated
When the signal gone out is low level, the coupling between the first signal wire Line1 and the first signal area Q1 leads to the first signal area
The grid potential that the current potential of Q1 reduces i.e. driving transistor Tc (P-type transistor) reduces, then the driving crystal in cut-off state
Pipe Tc may be switched on, and light emitting structure 10 can be caused to shine in the non-luminescent stage i.e. bright steathily, be influenced organic light emitting display panel
Display effect.
It follows that when the first signal that signal area Q1 is with driving transistor Tc is electrically connected in image element circuit structure 20

Although easily generating signal coupling between number line Line1, fixed current potential, the first signal wire are had based on shielding construction 30
The saltus step of the current potential of the signal of Line1 outputs does not interfere with the current potential of shielding construction 30.30 and first signal area of shielding construction
Although easily generating signal coupling between Q1, fixed current potential is had based on shielding construction 30, then the shielding construction 30 will not shadow
Ring the current potential of the first signal area Q1.It follows that after setting shielding construction 30, the pulse of the first signal wire Line1 outputs
