Age of 1Gyr and 1Gyr earlier from z~3
Fainter LBGs increase at the later epoch
Disagreement among UVLFs at z~4, 5

Ando et al. 2004
Dusty environment in luminous LBGs?
Fainter LBGs at z~3 are late comers?
Luminous z~5 LBGs in dusty environment?
chemically evolved to some degree?
=> lack of blue luminous ones?
Luminous z~5 LBGs show larger clustering amp.
luminous LBGs reside in massive DHs?
=> SF started eariler?Downsizing of LBGs?
LBGs will be obtained from
