Abstract

Provided is a pixel defining layer for pixels formed by ink jet printing, an array substrate and a display apparatus. The pixel defining layer comprises a first pixel defining sub-layer, which defines a plurality of uniformly distributed pixels; and a second pixel defining sub-layer on the first pixel defining sub-layer, wherein the second pixel defining sub-layer and the first pixel defining sub-layer together define a plurality of ink-holding spaces for the plurality of uniformly distributed pixels respectively, and wherein a width of the first pixel defining sub-layer is not less than a width of the second pixel defining sub-layer thereon, wherein the pixel defining layer is divided into an active area zone and an dummy zone outside the active area zone, and wherein an ink-holding space of a pixel in the dummy zone is larger than an ink-holding space of a pixel in the active area zone.
