A light-emitting substrate and a display apparatus, comprising: a base substrate; a first electrically conductive layer, located on the base substrate, the fit electrically conductive layer comprising multiple common voltage lines and multiple first connection lines spaced apart from each other, and the multiple common voltage lines extending along a first direction and being arranged along a second direction; a first insulating layer, located at a side of the first electrically conductive layer distant from the base substrate; and a second electrically conductive layer, located at a side of the first insulating layer distant from the base substrate. The second electrically conductive layer comprises multiple first bridge parts spaced apart from each other.
