Abstract
An organic light-emitting display substrate, a manufacturing method therefor, and an organic light-emitting display device. The organic light-emitting display substrate comprises a base substrate and multiple sub-pixels that are located on the base substrate and that are arranged in an array manner. Each sub-pixel comprises an organic light-emitting layer. At least one blocking element is disposed between two adjacent sub-pixels that emit light of different colors.
Claims17
An organic light-emitting display substrate, comprising a base substrate and a plurality of sub-pixels arranged in an array on the base substrate,
- wherein, each of the sub-pixels includes an organic light-emitting layer, and at least one blocking element is provided between two adjacent sub-pixels emitting light of different colors;
- wherein, a plurality of blocking elements are provided between two adjacent sub-pixels, each the blocking element has a strip shape, and a long side of each blocking element is parallel to a side edge of the sub-pixel which is close to the blocking element;
- the plurality of blocking elements between two adjacent sub-pixels are arranged in a staggered manner, and there is a gap between two adjacent blocking elements.
A fabrication method of an organic light-emitting display substrate, comprising:
- forming at least one blocking element between two adjacent sub-pixels emitting light of different colors on a base substrate;
- and
- forming an organic light-emitting layer in each of the sub-pixels;
- wherein, the organic light-emitting layer is formed after forming the blocking element;
- wherein, forming an organic light-emitting layer in each of the sub-pixels comprises:
- covering the base substrate on which the blocking element is formed with a mask,
- bringing the mask into contact with a top end of the blocking element, and
- forming the organic light-emitting layer in each of the sub-pixels by an evaporating process.
