Abstract

A display apparatus substrate includes a non-rectangular display region. The display region includes a main display region and edge display region(s) at the periphery of the main display region. The display region is provided with a plurality of pixels therein, and each pixel includes at least three sub-pixels. The display apparatus substrate includes a black matrix pattern and first metal patterns disposed in the edge display region(s). A portion of the black matrix pattern in the edge display area(s) has first openings, and a first opening is disposed in one corresponding sub-pixel in the edge display area(s). A first metal pattern corresponds to one first opening and is disposed in the corresponding sub-pixel, and an orthogonal projection of the first metal pattern on a reference plane overlapping a partial region of an orthogonal projection of the corresponding first opening on the reference plane.
