We present the recent results from NICMOS/HST parallel survey to find emission-line galaxies using the grism spectra. The survey covers 130 arcmin2 at 140 different locations, free of cosmic variance and selection biases. Roughly one emission-line galaxy per one field is found. Most of the emission lines are thought to be Hα redshifted to 0.7 ≤ z ≤ 1.9, while there are other possibilities of different lines at different redshifts. From these galaxies, we construct Hα luminosity function over a wide range that will provide a good measure for global star formation rate density at z 1.5. Additionally, evolution of Hα luminosity function along the redshift and the relationship between Hα-derived star formation rate and other parameters are discussed.
