A process for forming an organic semiconducting layer having molecular alignment. First, a photoalignment organic layer is formed on a substrate or A dielectric layer. Next, the photoalignment organic layer is irradiated by polarized light through a mask, such that the photoalignment organic layer becomes an orientation layer having molecular alignment. Finally, an organic semiconducting layer is formed on the orientation layer, such that the organic semiconducting layer aligns according to the alignment of the orientation layer to exhibit molecular alignment. The present invention can form an organic semiconducting layer with different molecular alignments in different regions over the same substrate by means of polarized light exposure through a mask.

A pixel structure of a full-color organic light-emitting diode (OLED) display device comprises a black matrix, a color changing medium, two thin film transistors, a storage capacitor, and an OLED device arranged on a substrate. The pixel structure of the display device uses blue organic light-emitting diodes or polymer light-emitting diodes as electroluminescent media. The low-temperature poly Si (LTPS) thin film transistors provide a current to the OLED device and serve as an active driving device. The color changing medium changes blue light into red or green light to form full-color OLED. The processing steps include the black matrix process, the island process, the gate process, the interlayer process, the color changing medium process, and the OLED deposition process. Because a color changing medium is integrated on the LTPS thin film transistors, this invention can make display devices of high resolution, high luminous efficiency and wide viewing angle.

The invention provides a TFT electrode structure and its manufacturing method that can prevent metal diffusion occurring in the fabrication of a TFT, and thereby reduce the risk of contamination of the chemical vapor deposition process due to metallic ion diffusion. The transparent pixel electrode is formed after the gate electrode metal so that the pixel transparent electrode can be used as a barrier layer to prevent metal diffusion under high temperature from the gate electrode metal to adjacent insulating layers or the active layer. Further, the method used to form the transparent pixel electrode is a low-temperature physical vapor deposition process, which affected less by the processing environment, and the transparent pixel electrode is a conductive layer that is not affected by metal diffusion.

The pixel structure of the display device comprises two thin film transistors, a storage capacitor, a color filter, and an OLED device structure constructed on a top surface of a substrate, a black matrix region outside the color filter region and under the thin film transistors.

This simplifies the process, reduces the leakage of light and increases the contrast of the display device. A white OEL device is used to emit light. A light then passes a color filter to get red, green or blue color of light. Therefore, a full-color OLED is formed. A poly-silicon thin film transistor is used to provide current to the OLED device structure and served as an active drive device. The advantages of the display device include simple fabrication process, high-resolution, high lighting efficiency and wide viewing angle.
