Definitions

  • FIG. 1 is a plan view schematically showing a display according to a first embodiment of the present invention
  • FIG. 8 is a sectional view showing the organic EL elements of the organic EL display according to a comparative example
  • FIG. 27 is a flow chart showing an example of the manufacturing process for the display according to the sixteenth embodiment of the present invention.
  • the video signal line driver XDR outputs a video signal as a current signal (write current) I sig to each of the video signal lines DL, so as to set the gate-to-source voltage V gs of the drive transistor DR at a value corresponding to the magnitude of the video signal I sig .
  • the scan signal line driver YDR outputs a scan signal for opening the switching transistors SWb and SWc as a voltage signal to the scan signal line SL 2 to which the selected pixels PX 1 to PX 3 are connected.
  • the scan signal line driver YDR outputs a scan signal for closing the switching transistors SWa as a voltage signal to the scan signal line SL 1 to which the selected pixels PX 1 to PX 3 are connected. This terminates the selection period.
  • the regions of the emitting layer EML 1 corresponding to the emitting portions EA 1 and EA 2 are different in electrical characteristics from the region of the emitting layer EML 1 corresponding to the emitting portion EA 3 .
  • the regions of the emitting layer EML 1 corresponding to the emitting portions EA 1 and EA 2 are lower in hole mobility and/or hole injection efficiencies than the region of the emitting layer EML 1 corresponding to the emitting portion EA 3 .
  • the first and second exposures increase the hole mobilities and/or hole injection efficiencies of the emitting layers EML 1 and EML 2 at the irradiated regions.
  • the first and second exposures decrease the electron mobilities and/or electron injection efficiencies of the emitting layers EML 1 and EML 2 at the irradiated regions. In this case, the same effect as described above can be achieved.
  • the hole injection layer HIL is interposed between the pixel electrodes PE and the emitting layer EML 1 .
  • the hole-transporting layer HTL is interposed between the hole injection layer HIL and the emitting layer EML 1 .
  • the electron injection layer HIL is interposed between the counter electrode CE and the emitting layer EML 3 .
  • the electron-transporting layer ETL is interposed between the electron injection layer HIL and the emitting layer EML 3 .
  • each of the hole injection layer HIL, the hole-transporting layer HTL, the electron injection layer HIL and the electron-transporting layer HTL is a continuous layer extending over the display region.
  • the material of the counter electrode CE for example, aluminum is used.
  • the thickness of the counter electrode CE is, for example, 150 nm.
  • FIG. 25 is a flow chart showing an example of the manufacturing process for the display according to the fourteenth embodiment of the present invention.
