We investigate the evolution of the universal rest-frame ultraviolet luminosity density from z = 1.5 to the present .
We analyze an extensive sample of multicolor data ( U ^ { \prime } _ { AB } , B _ { AB } , V _ { AB } = 24.5 ) plus spectroscopic redshifts from the Hawaii Survey Fields and the Hubble Deep Field .
Our multicolor data allow us to select our sample in the rest-frame ultraviolet ( 2500 Å ) over the entire redshift range to z = 1.5 .
We conclude that the evolution in the luminosity density is a function of the form ( 1 + z ) ^ { 1.7 \pm 1.0 } for a flat lambda ( \Omega _ { { m } 0 } = 0.3 , \Omega _ { \lambda 0 } = 0.7 ) cosmology and ( 1 + z ) ^ { 2.4 \pm 1.0 } for an Einstein-de Sitter cosmology .
