Pixel having an organic light emitting diode and method of fabricating the pixel

摘要

A pixel having an organic light emitting diode (OLED) and method for fabricating the pixel is provided. A planariza-tion dielectric layer is provided between a thin-film transistor (TFT) based backplane and OLED layers. A through via between the TFT backplane and the OLED layers forms a sidewall angle of less than 90 degrees to the TFT backplane. The via area and edges of an OLED bottom electrode pattern may be covered with a dielectric cap.
