摘要:
Embodiments of the present disclosure provide an organic electroluminescence display device. The display device may include a set of multi-directional spacers that are interposed between the pixels of the display. In one embodiment, the spacers are positioned in both lengthwise and crosswise directions. In another embodiment, the spacers include a first portion that is extends lengthwise between pixels and one or more portions that extend laterally from the first portion between pixels. In yet another embodiment, the spacers include portions that extend in multiple directions between pixels. The spacers may substantially surround each of the pixels and may serve as a boundary, for example, that prevents organic material for one pixel from being incorrectly deposited in another pixel. The spacers can be configured as a support structure, such as, for a metal mask during fabrication of the display device. In addition, the multi-directional aspect of the spacers may be useful in protecting the pixels from damage, such as, when a metal mask is moved during mounting or during fabrication of the display device.
