Abstract: A display panel having a pixel defining layer defining subpixel apertures of subpixels is provided. The pixel defining layer is a unitary structure including column portions and row portions. A respective row portion is between two adjacent subpixel apertures that are in a same column and respectively from two adjacent rows. A respective column portion is in a space between two adjacent columns of subpixel apertures, spacing apart multiple pairs of adjacent row portions respectively in multiple rows. A respective row portion includes a depression part configured to allow fluid communication of an ink solution between the two adjacent subpixel apertures in the same column and respectively from the two adjacent rows. A minimum height of the depression part relative to a base substrate is less than a minimum height of a column portion adjacent to the respective row portion relative to the base substrate.
