    Abstract: A mask plate and a method for manufacturing the same are provided. The mask plate comprises a first sub-mask plate and a second sub-mask plate stacked with each other, the first sub-mask plate is provided with at least one first opening therein, a size and a shape of the first opening correspond to those of a target display panel; the second sub-mask plate is provided with a second opening region, which covers at least one of the at least one first opening and includes a plurality of second openings. Since it is only required to ensure that the sizes and shapes of the first openings are the same as those of the target display panels respectively, and it is unnecessary to further manufacture openings for forming pixel patterns, comparing with the existing mask plate, the manufacturing process of the present disclosure is more simple and the manufacturing cost is lower.
