An organic light emitting display device according to an embodiment includes a lower substrate; a bank layer disposed on the lower substrate; a connection assistance unit disposed on the bank layer; a cathode disposed on the lower substrate so as to cover the bank layer; an auxiliary electrode disposed on the bank layer and electrically connected with the cathode; and an upper substrate provided to face the lower substrate.

Organic light emitting display device and method for manufacturing the same

An organic light-emitting diode (OLED) display panel includes: an OLED layer; a color filter layer; and a color coordinate tuning layer disposed between the OLED layer and the color filter layer, wherein the OLED layer includes a first light-emitting portion comprising a first light-emitting layer configured to emit a first light and a second light-emitting portion comprising a second light-emitting layer configured to emit a second light. The OLED layer is configured to emit a third light produced by mixing the first light and the second light. The color coordinate tuning layer is configured to output a fourth light different from the third light. The number of all of peaks and shoulders that an EL spectrum of the fourth light has is higher than the number of all of peaks and shoulders that an EL spectrum of the third light has throughout an entire range of a visible wavelength band.

Organic light emitting diode display panel

An organic light emitting display element includes a substrate, a lower electrode positioned on the substrate, at least one organic light emitting layer positioned on the lower electrode, a metal doped layer positioned on the organic light emitting layer, and an upper electrode positioned on the metal doped layer that includes a conductive material, and is configured to transmit light. Such organic light emitting display element is capable of minimizing degeneration and damage to the organic light emitting layer caused by sputtering.
