A liquid crystal display bottom substrate with bumps is disclosed, which comprises: one thin film transistor located on a surface of a substrate, a passivation layer covered over the surface of the thin film transistor and that of the substrate, and a reflective metal layer formed over the passivation layer. A plurality of bumps are formed on the surface of the passivation layer, wherein the bumps have asymmetric shapes in the cross sections, and the projection of the center of said bumps on the substrate is not overlapped with the projection of the peak of the same bumps.
