We present a universal linear correlation between the stellar mass and surface brightness (SB) of galaxies at 0.3 < z < 3, using a deep K-band-selected catalog in the GOODS-North region. The correlation has a nearly constant slope, independent of redshift and color of galaxies in the rest-z frame. Considering unresolved compact galaxies, the tight correlation gives a lower boundary of SB for a given stellar mass; lower SB galaxies are prohibited over the boundary. The universal slope suggests that the stellar mass in galaxies was built up over their cosmic histories in a similar manner irrelevant to galaxy mass, as opposed to the scenario that massive galaxies mainly accumulated their stellar mass by major merging. In contrast, SB shows a strong dependence on redshift for a given stellar mass. It evolves as approx(1 + z){sup -2.0a}pprox{sup -0.8}, in addition to dimming as (1 + z){sup 4} by the cosmological expansion effect. The brightening depends on galaxy color and stellar mass. The blue population (rest-frame U - V < 0), which is dominated by young and star-forming galaxies, evolves as approx(1 + z){sup -0.8+}-{sup 0.3} in the rest-V band. On the other hand, the red population (U - V>0) and the massive galaxies (M{sub *}>10{sup 10} M{sub sun}) show stronger brightening, (1 + z){sup -1.5+}-{sup 0.1}. By comparison with galaxy evolution models, the phenomena are well understood by the pure luminosity evolution of galaxies out to z approx 3.
