Abstract

A display apparatus including a driving circuit substrate, a first bank layer, a plurality of light-emitting elements, an opposite substrate, a second bank layer and an encapsulation layer. The first bank layer is disposed on the driving circuit substrate and has a plurality of openings. The plurality of light-emitting elements are disposed in the plurality of openings of the first bank layer. The opposite substrate is disposed opposite to the driving circuit substrate. The second bank layer is disposed on the opposite substrate. The second bank layer includes a plurality of bank blocks. The plurality of bank blocks are separated from each other and have a plurality of gaps. At least one of the plurality of light-emitting elements overlaps at least one of the plurality of gaps. The encapsulation layer is disposed on the plurality of bank blocks and in the plurality of gaps between the plurality of bank blocks.
