Abstract:
The present invention provides an array substrate, an OLED display panel, and a mask. The array substrate includes a predetermined film-forming region and a non-film forming region. The non-film forming region is provided with a shadow region close to the predetermined film-forming region. An actual film forming region of a film layer to be formed on the array substrate includes the predetermined film-forming region and the shadow region. The array substrate is provided with a groove or a protrusion in the corresponding shadow region, so that the film layer is disconnected at the corresponding groove or the protrusion to form a discontinuous film.
