first embodiment

[0057]FIG. 1 is a schematic cross-sectional view of an organic light emitting diode display device constructed with a

[0058]Referring to FIG. 1, the organic light emitting diode display device 100 constructed with the first embodiment includes a substrate 11, a display unit 110 formed on the substrate 11, a sealing substrate 14 fixed to the substrate 11 by bonding layers 12 and 13 surrounding the display unit 110. The substrate 11 includes a display area A10 within which the display unit 110 is positioned and a nondisplay area positioned outside of the display area A10. The nondisplay area may be partitioned into a wire and sealing area A20 and a pad area A30.

[0059]The display unit 110 includes a plurality of pixels, and an organic light emitting diode and a driving circuit unit are formed in each pixel. The organic light emitting diode includes a pixel electrode and an organic emission layer, and a common electrode 15. The driving circuit unit is constituted by at least two thin fil...

second embodiment

[0118]FIG. 11 is a schematic cross-sectional view of an organic light emitting diode display device constructed with a second embodiment and FIG. 12 is a partially enlarged diagram of the organic light emitting diode display device shown in FIG. 11.

[0119]Referring to FIGS. 11 and 12, the organic light emitting diode display device 200 of the second exemplary embodiment has a similar configuration as the organic light emitting diode display device of the first embodiment except for a configuration in which the second pad section is omitted and the second internal layer 31 formed on the sealing substrate 14 is in contact with the common electrode 150. The same members as the first embodiment refer to the same reference numerals.

[0120]In the display unit 110, the common electrode 150 has an uneven structure, that is, a plurality of protrusions 151 and the protrusions 151 are in close contact with the second internal layer 31 formed on the sealing substrate 14. Therefore, the common ele...

third embodiment

[0123]Referring to FIG. 13, in the organic light emitting diode display device 300 of the third embodiment, the first common power supply line is divided into a first odd number-th common power supply line and a first even number-th common power supply line, and the second common power supply line is divided into a second odd number-th common power supply line and a second even number-th common power supply line. The first odd number-th common power supply line and the second odd number-th common power supply line are applied with a third signal and the first even number-th common power supply line and the second even number-th common power supply line are applied with a fourth signal. Such a structure is in use for driving interlace scanning.

[0124]The first pad section for the common power supply line formed on the substrate 11 includes a third pad section 76 for the first odd number-th common power supply line and the second odd number-th common power supply line and a fourth pad ...
