Abstract
A pixel demarcation layer includes a first pixel demarcation sub-layer and a second pixel demarcation sub-layer stacked on the first pixel demarcation sub-layer. The pixel demarcation layer is divided into a display area and an edge area located outside the display area. The first pixel demarcation sub-layer includes a plurality of first openings positioned within the display area each corresponding to a light-emitting region of a respective sub-pixel unit. The second pixel demarcation sub-layer includes a plurality of second openings each coated with an organic light-emitting material. Each of the second openings includes a first area positioned in the display area and corresponding to a set of the first openings. Each of the second openings also includes a second area positioned in the edge area and configured to provide an initiating terminal from which the first area corresponding to the second area is coated with the organic light-emitting material.
