Abstract

The present invention relates to color organic light emitting diode (OLED) display devices having reduced color cross-talk between sub-pixels. Specifically, the present invention relates to color OLED display devices having a reflective barrier structure between adjacent color changing materials and/or color filters. The reflective barrier structure reduces color cross-talk effects by reflecting stray light into the color filter and/or color materials and toward the viewer. The present invention further relates to a method of fabricating an OLED display device having reduced color cross-talk between sub-pixels.
