Abstract:
A process for forming an organic device, comprising the following steps:forming a photoalignment organic layer on a substrate or a dielectric layer; irradiating the photoalignment organic layer by polarized light through a mask, such that the photoalignment organic layer becomes an orientation layer having molecular alignment; forming an organic semiconducting layer on the orientation layer, such that the organic semiconducting layer aligns according to the alignment of the orientation layer to exhibit molecular alignment; and forming an electrode, wherein the organic device is an organic light emitting diode (OLED) and the process includes the following steps: irradiating the photoalignment organic layer by polarized light, such that the photoalignment organic layer becomes an orientation layer having molecular alignment; and forming an organic semiconducting layer on the orientation layer to serve as a luminescent layer, such that the organic semiconducting layer aligns according to the alignment of the orientation layer to exhibit molecular alignment; and successively forming an electron transfer layer and a cathode on the organic semiconducting layer.
