Support plates, display apparatuses and electronic devices

A display apparatus, comprising a display panel and a support plate, wherein the support plate comprises:

• a plurality of flat region, comprising a first flat region and a second flat region spaced apart along a first direction;
• a bendable region, connected between the first flat region and the second flat region;
• a pattern region, covering at least the bendable region, wherein a plurality of hole groups arranged along the first direction are disposed in the pattern region, each of the hole groups comprises a plurality of holes spaced at intervals along a second direction, at least two of the plurality of holes in a part of the pattern region covering the bendable region are formed into oblique holes, a central axis of each of the oblique holes intersects with a thickness direction of the bendable region at a non-zero included angle, wherein the second direction is perpendicular to the first direction, the central axis of each of the oblique holes is located in a first datum plane which is parallel to a plane formed by intersecting the thickness direction of the bendable region with the first direction;
• the bendable region bends along the thickness direction which is perpendicular to the first direction and the second direction, and the support plate is supported at a back side of the display panel.
