Patent ID: 11402710

Abstract:
A display substrate may include at least one connection structure (1) in a non-display area (89) of the display substrate. The at least one connection structure (1) may include a first conductive layer (11), at least one insulating layer (19) on the first conductive layer (11), and a second conductive layer (12) on a side of the at least one insulating layer (19) opposite from the first conductive layer (11). The second conductive layer 12) may be connected to the first conductive layer (11) through a plurality of via holes (3) in the at least one insulating layer (19), and at least two of the plurality of via holes (3) may have different contact areas with the first conductive layer (11). The display substrate can be at least partially solves the problem that the through hole is easy to be burnt when over-current problem.
