OLED array substrate, manufacturing method thereof, OLED display panel

A manufacturing method of an OLED array substrate, comprising:

• forming a first electrode layer, a pixel definition layer, an organic material functional layer and a second electrode layer successively,
• wherein
• the organic material functional layer comprises light-emitting regions that emit light of different colors,
• the pixel definition layer comprises pixel regions corresponding to the light-emitting regions and spacing regions arranged between adjacent pixel regions,
• wherein forming the organic material functional layer comprises forming a first functional layer, a light-emitting layer and a second functional layer successively, and each spacing region comprises a first spacing portion and a second spacing portion arranged successively in a light exit direction, the first spacing portion being configured to separate portions of at least the first functional layer corresponding to respective light-emitting regions from each other.

An OLED display panel comprising an OLED array substrate, the OLED array substrate comprising a first electrode layer, a pixel definition layer, an organic material functional layer, and a second electrode layer arranged successively in a light exit direction,

• wherein
• the organic material functional layer comprises light-emitting regions being configured to emit light of different colors,
• the pixel definition layer comprises pixel regions corresponding to the light-emitting regions and spacing regions arranged between adjacent pixel regions,
• wherein the organic material functional layer comprises a first functional layer, a light-emitting layer, and a second functional layer arranged successively in the light exit direction, and each spacing region comprises a first spacing portion and a second spacing portion arranged successively in the light exit light, the first spacing portion being configured to separate portions of at least the first functional layer corresponding to respective light-emitting regions from each other.
