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.

Organic light emitting display device

A highly fluorinated photoresist employing a photodimerization chemistry and a method for manufacturing an organic light emitting diode display using the same. The photoresist includes a copolymer that is made from two different monomers. When the copolymer is used as a photoresist, the photoresist has the characteristic that it becomes insoluble when exposed to an ultraviolet light having a wavelength of 365 nm.
