Array substrate and display device

An array substrate, comprising:

• a base substrate, comprising a display region and a peripheral region at the periphery of the display region;
• a pixel driving layer on the base substrate;
• an organic light emitting element on the pixel driving layer;
• a package layer on the organic light emitting element, the package layer comprising a first inorganic package layer and an organic package layer which are sequentially arranged;
• a plurality of first transmission lines in the peripheral region and at a side of the package layer away from the base substrate, each of the plurality of first transmission lines extending along a first direction, and the plurality of first transmission lines being arranged along a second direction, the second direction being substantially perpendicular to the first direction;
• wherein, in the peripheral region, the first inorganic package layer comprises a first inorganic package portion, an inorganic package connection portion and a second inorganic package portion which are continuously arranged in a direction from the display region to the peripheral region, and the inorganic package connection portion is configured to connect the first inorganic package portion and the second inorganic package portion;
• in the peripheral region, the organic package layer comprises a first organic package portion and a second organic package portion which are arranged continuously in the direction from the display region to the peripheral region, an edge of the second organic package portion away from the display region is an edge of the organic package layer, and an orthographic projection of the first organic package portion on the base substrate is overlapped with orthographic projections of the first inorganic package portion and the inorganic package connection portion on the base substrate, and an orthographic projection of the second organic package portion on the base substrate is overlapped with an orthographic projection of the second inorganic package portion on the base substrate;
• in a direction perpendicular to the base substrate, a distance d1 between the first inorganic package portion and the base substrate is larger than a distance d2 between the second inorganic package portion and the base substrate, and an orthographic projection of at least one of the plurality of first transmission lines on the base substrate falls within the orthographic projection of the second inorganic package portion on the base substrate.
