Abstract: The present disclosure provides a thin-film transistor and a method for manufacturing the same, an array substrate, and a display device. The thin film transistor of the present disclosure include a plurality of insulating layers, among which at least one insulating layer on the low temperature polysilicon layer comprises organic material, so vias could be formed in the organic material by an exposing and developing process, thereby effectively avoiding the over-etching problem of the low temperature polycrystalline silicon layer caused by dry etching process. By adopting the method for manufacturing the film transistors of the present disclosure, the contact area and uniformity of the drain electrode and the low temperature polysilicon material layer can be increased; the conductivity can be improved; and the production cycle of products can be greatly reduced and thereby improving the equipment capacity.

Abstract: A screen plate, a packaging method, a display panel and a display device are provided. The screen plate includes a frame, a mesh fixed onto the frame and a masking film arranged on the mesh. A printing area is formed in a portion of the mesh that is not masked by the masking film. At least one masking line is arranged in the printing area. The at least one masking line is arranged along an edge of the masking film respectively. A width of the masking line is greater than a width of each mesh line of the mesh.
