Estimating the term…
An organic electro luminescence display panel includes a hole transport layer and a luminescent layer disposed on the hole transport layer. The luminescent layer includes at least first and second luminescent layers. The first and second luminescent layers are repeatedly arranged on the hole transport layer so as to be adjacent each other. The first luminescent layer includes a first dopant for emitting a first light having a first wavelength, and the second luminescent layer includes a second dopant for emitting a second light having a second wavelength, which is shorter than the first wavelength. No first dopant is disposed between the hole transport layer and the second luminescent layer.
An organic electro luminescence display panel comprising:
An organic electro luminescence display panel comprising:
A method for manufacturing an organic electro luminescence display panel, which includes a hole transport layer and a luminescent layer disposed on the hole transport layer, wherein the luminescent layer includes at least first and second luminescent layers, which are repeatedly arranged on the hole transport layer so as to be adjacent each other, and wherein one of the first and second layers includes a hole transporting material as a host material, the method comprising the step of:
