Abstract
Disclosed are an array substrate, a preparation method, a display panel, and a display device. A pixel limiting layer includes a first limiting sublayer and a second limiting sublayer which contact each other, and a first height of the first limiting sublayer in a direction perpendicular to a plane where a base substrate is located is greater than a second height of the second limiting sublayer in the direction perpendicular to the plane where the base substrate is located. Thus, when light emitting layers are formed in pixel openings by an ink jet printing process, light emitting layers having different colors can be spaced apart by the first limiting sublayer.
