The present disclosure provides a pixel circuit, a pixel circuit driving method and a display device. The pixel circuit includes a plurality of row pixel units. Each row pixel unit includes a plurality of subpixel units. Each of the subpixel units includes a subpixel driving circuit and a light-emitting component. Each row pixel unit further includes a row sharing unit. Each of the subpixel units is coupled with a first signal line and a second signal line; the row sharing unit is coupled with each subpixel unit included in the row pixel unit through the first signal line and the second signal line, to have a threshold compensation function.
